(産業上の利用分野)
本考案は洗濯機の注水すすぎ制御装置に関する
ものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a water injection rinsing control device for a washing machine.
(従来の技術)
洗濯機における注水すすぎは、水槽に注水しな
がら水を溢水口よりオーバーフローさせることに
行なうものである為、排水ホースを倒し忘れてい
たり排水ホースが折曲され排水性能が低下してい
たりすると、水槽内の水位が異常に上昇し、最終
的に水槽の上端から水が溢れ出るという異常溢水
現象を生じるものである。(Conventional technology) Water rinsing in a washing machine is performed by pouring water into the water tank and letting the water overflow from the overflow port, so there are cases where the drain hose is forgotten to be turned down or the drain hose is bent, resulting in poor drainage performance. If this happens, the water level in the aquarium will rise abnormally, and water will eventually overflow from the top of the aquarium, resulting in an abnormal overflow phenomenon.
このような異常溢水現象を防止する為、従来に
おいては水槽内の水位がオーバーフロー水位を越
え異常に上昇してきた時に、その水位変化を検知
して注水及びモータを停止し、注水すすぎの実行
を中止するように構成していた。 In order to prevent such abnormal water overflow phenomena, in the past, when the water level in the water tank exceeds the overflow water level and abnormally rises, the change in water level is detected and the water injection and motor are stopped, and water injection rinsing is stopped. It was configured to do so.
(考案が解決しようとする問題点)
ところで、従来のように注水すすぎの実行を中
止してしまうと、使用者がその中止に直ちに気付
かず、すすぎ時間が経過した頃になつて始めて気
付く場合があり、このような場合にはその間の時
間が全く無駄となり、改めてすすぎ作業を行なう
必要があつた。(Problem that the invention seeks to solve) By the way, if water injection rinsing is stopped as in the past, the user may not notice the cancellation immediately and may only notice it after the rinsing time has elapsed. In such a case, the time was wasted and it was necessary to carry out the rinsing process again.
然るに、本考案にあつては、排水ホースの倒し
忘れ等により水位が異常上昇した時に、注水すす
ぎをためすすぎに変えて続行することにより、時
間の無駄を省くものである。 However, with the present invention, when the water level rises abnormally due to forgetting to turn down the drain hose, etc., the water injection rinse is changed to a sample rinse and continued, thereby eliminating wasted time.
(問題点を解決するための手段)
本考案の内容は、注水しながらすすぎ作業を行
う洗濯機で、水槽内の水位がオーバーフロー水位
より高く設定した異常水位に達したことを検出し

ータを停止したりする注水すすぎ制御装置におい
て、前記検出器の異常信号出力により注水動作の
みを停止してモータの運転を継続しすすぎ作業を
続行させる手段を備えるものである。(Means for solving the problem) The content of the present invention is to detect that the water level in the water tank has reached an abnormal water level set higher than the overflow water level in a washing machine that performs rinsing work while pouring water, and to send an abnormal signal. In a water injection rinsing control device that is provided with a detector that outputs an error signal and stops the water injection operation or stops the motor when an abnormal signal is output from the detector, only the water injection operation is stopped when the abnormal signal is output from the detector. It is provided with a means for continuing the operation of the motor and continuing the rinsing operation.
(作用)
注水すすぎにおいて、排水ホースの倒し忘れや
排水ホースの折曲により水槽内の水位がオーバー
フロー水位を越え異常水位まで達すると、検出器
はこれを検出して異常信号を出力する。すると、

ものの、すすぎ作業を続行できることになり、時
間の無駄がなくなる。(Function) During water injection rinsing, if the water level in the water tank exceeds the overflow level and reaches an abnormal water level due to forgetting to turn down the drain hose or bending the drain hose, the detector detects this and outputs an abnormal signal. Then,
By stopping water injection in response to the output of the abnormal signal, further rise in water level is suppressed to prevent abnormal water overflow, and rinsing work is continued with water injection stopped. Therefore, although water pouring rinsing is changed to water rinsing, the rinsing work can be continued, and time is not wasted.

以下第1図及び第2図に示した本考案の実施例
について詳細に説明する。(Example) Hereinafter, the example of the present invention shown in FIGS. 1 and 2 will be described in detail.

信号を出力する検出器として作用する。 FIG. 1 is a schematic diagram of a washing machine according to an embodiment of the present invention. In the figure, 1 is a water tank, 2 is a washing and dewatering tank, 3 is a pulsator, 4 is a motor, 5 is a drain port at the bottom of the tank 1, 6 is an overflow port at the top of the side of the tank 1, 7 is a drain valve, and 8 is a The water supply valve 9 is a drain hose connected to the drain port 5 via a drain valve 7 and to the overflow port 6 via an overflow hose 10, and is folded down during use as is well known in the art. 11 is a float switch installed at the tip of the overflow hose 10, which is turned ON when the water level in the water tank 1 reaches an abnormal water level Y that is set higher than the overflow water level It acts as a detector that outputs a signal.

にすすぎ工程を制御する。 Fig. 2 is a block diagram showing the control system of the washing machine, where A is the electronic control circuit mainly composed of a microcomputer, and B is the float switch 1.
1. A detection unit including a water level switch (not shown) that detects changes in the water level in the water tank 1 by pressure changes, C
is the load of the motor 4, drain valve 7, water supply valve 8, etc., D
indicates a key input section, and E indicates a display section. Thus, the electronic control circuit section A controls the rinsing process as shown in the flowchart shown in the third figure.
次に、第3図のフローチヤートに従つて動作を
説明する。 Next, the operation will be explained according to the flowchart shown in FIG.
すすぎ工程が開始すると、先ず給水弁8を開い

の水位が設定水位に達して水位スイツチがONと
なり、この時注水すすぎが設定されていると給水
弁8を開いたままモータ4を駆動し、注水すすぎ
作業を開始する。 When the rinsing process starts, first, the water supply valve 8 is opened to start pouring water into the water tank 1. Then, when the water level in the water tank 1 reaches the set water level, the water level switch is turned on, and if water injection rinsing is set at this time, the motor 4 is driven with the water supply valve 8 open, and the water injection rinsing work is started.

水能力を発揮している場合には、水槽1内の水が
オーバーフローにより溢水口6から溢水ホース1

槽1内の水位はオーバーフロー水位Xを越えるこ
とはない。 During rinsing, if the drain hose 9 is knocked down and exhibits normal drainage capacity, the water in the water tank 1 will overflow and drain from the overflow port 6 to the overflow hose 1.
0. Since the water is drained to the outside via the drain hose 9, the water level in the water tank 1 never exceeds the overflow water level X.

る。 If the drain hose 9 is forgotten to be turned down, the water in the tank 1 will not be drained, and the water level in the tank 1 will rise above the overflow water level X and reach the abnormal water level Y. Then, the float switch 11 is turned on, and accordingly, the electronic control circuit section A immediately closes the water supply valve 8 to stop water injection, and performs the subsequent rinsing operation by changing it to a trial rinse, and the rinsing time elapses. Continue until. At this time, the water level in the aquarium 1 will not rise above the abnormal water level Y due to the stoppage of water injection, and therefore, an abnormal overflow phenomenon in which water overflows from the upper end of the aquarium 1 is prevented.
