産業上の利用分野
本発明は少なくとも上端を除く周壁を無孔壁と
し、脱水および洗濯を行うべく設けた内槽を備え

濯及びすすぎ時の水位を設定するダイヤフラム機
構を有した圧力スイツチにおけるトリツプ圧力お
よびリセツト圧力の設定に係るものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dehydrating/washing machine having a non-porous peripheral wall except for at least the upper end and an inner tub provided for dehydrating and washing. This invention also relates to the setting of trip pressure and reset pressure in a pressure switch having a diaphragm mechanism for setting the water level during rinsing.
従来例の構成とその問題点
従来、周壁を無孔壁とした内槽を有した脱水兼
用洗濯機の水位検知方式としては、電極方式と、
ダイヤフラム機構を有した圧力スイツチ方式の２
つがある。Conventional configurations and their problems Conventionally, water level detection methods for dehydrating and washing machines having an inner tub with a non-porous surrounding wall include an electrode method,
Pressure switch type 2 with diaphragm mechanism
There is one.
このうち、電極方式は、内槽上部に溢水用小孔
を設け、給水によりこの小孔を介して内槽外に水
を溢れ出させ、この溢水を前記小孔の近傍に設け
た電極板に接触させ、電極板が水を介し電気的に
導通したことを確認する方式である。この方式に
よれば、内槽に設けた溢水用小孔の設定位置が１
段階しか得られず、その結果複数段の水位設定が
不可能であり、特に、洗濯衣類が少ない場合等
は、水を使い過ぎてしまうという欠点を有し、
又、同時に制御回路を必要とし、コスト的にも高
いものになるという欠点があつた。 Among these, the electrode method has a small overflow hole in the upper part of the inner tank, and when water is supplied, water overflows to the outside of the inner tank through this small hole, and this overflow water is sent to an electrode plate installed near the small hole. This is a method to confirm that the electrode plate is electrically conductive through water. According to this method, the setting position of the small overflow hole provided in the inner tank is 1.
As a result, it is impossible to set water levels in multiple stages, and this method has the drawback of using too much water, especially when there are few clothes to be washed.
Moreover, it also requires a control circuit and has the disadvantage of being expensive.
これに対して、ダイヤフラム機構を有した圧力
スイツチ方式は、その機構が簡単であり信頼性に
優れ、内槽内の洗濯水位の設定に対しては周知の
如く、簡単なバネ機構で、複数段又は無段階の切
り換えが可能である。 On the other hand, the pressure switch system with a diaphragm mechanism has a simple mechanism and is highly reliable.As is well known, the pressure switch system with a diaphragm mechanism has a simple spring mechanism and multiple levels for setting the washing water level in the inner tub. Or stepless switching is possible.
しかしながらこの方式においても次の如き問題

ヤフラム機構の圧力スイツチは、モータへの突入
電流の関係上、速断・速入機構にする必要があ

設け、内槽内の水圧が増加して、スイツチが
OFFの状態からONへの切り換わる点（トリツプ
点）と、逆に水圧が減じ、ONの状態からOFFの
状態へ切り換わる点（リセツト点）を存在せしめ
ている。 However, this method also has the following problems. That is, when the motor is used as a load, the pressure switch of the diaphragm mechanism needs to be a quick-turn/quick-on mechanism due to the inrush current to the motor. Therefore, we installed a toggle mechanism that uses the reaction force of the spring, and the water pressure in the inner tank increases, causing the switch to turn off.
There is a point at which the water pressure switches from OFF to ON (trip point) and a point at which water pressure decreases and switches from ON to OFF (reset point).
前述した如く、トリツプ点は、内槽内の水位に

リツプ状態を示した場合でも、洗濯運転中の回転
翼によつて生ずる吸込負圧により、再びリセツト
状態を呈した場合には、モータの運転が停止して
しまうものであつた。 As mentioned above, the trip point can be set by the water pressure obtained from the water level in the inner tank, but even if a trip state is once indicated, it cannot be reset again due to the suction negative pressure generated by the rotary blades during washing operation. If this occurs, the motor would stop operating.
又、すすぎ行程の場合、内槽の回転により発生
する遠心力により、水位が放物線形状を描き、中
心部の水位は、最初の設定値よりも低下してしま
う為に、リセツト状態を生ずることが多く見られ
た。 In addition, during the rinsing process, the centrifugal force generated by the rotation of the inner tank causes the water level to form a parabolic shape, and the water level in the center drops below the initial set value, which can cause a reset condition. Seen a lot.

たすすぎ行程中の問題に関しては、具体的な解決
手段が提案されていないのが現状である。 Conventionally, as a countermeasure to this problem, the lower surface of the rotor blade was made as smooth as possible during the washing process.
There are systems that minimize the generation of negative pressure by the rotor blades, and although they are somewhat effective, they are still not sufficient. Note that, at present, no specific solution has been proposed for the above-mentioned problems during the rinsing process.

作を防ぐものである。Purpose of the Invention In view of the above-mentioned conventional problems, the present invention prevents malfunction of the pressure switch due to suction negative pressure generated by high-speed rotation of the rotor blade, and prevents the water level from decreasing due to the rotation of the inner tank during the rinsing process. This prevents malfunction.

溜めケース１８内、および通水管２１内も同様に
水で満たされる。この時、排水弁２３は閉成状態
にある。 First, when a timer (not shown) is turned on, water is started to be supplied into the inner tub 2 from the water supply valve (not shown) built into the upper part of the housing 1 of the washing machine.
is filled with water, and the inside of the water reservoir case 18 and the inside of the water pipe 21 are also filled with water via the water port 10. At this time, the drain valve 23 is in a closed state.

なる。 In this state, the washing water level setting pressure switch 22
The pressure acting on is the arbitrary water level l 1 (mm) in the inner tank 2.
and the distance L (mm) between the bottom of the inner tank 2 and the water pipe 21
The water pressure obtained by the water height is L+l 1 (mmH 2 O).
今、圧力スイツチ２２のトリツプ点作動圧力を

伝えられ、回転翼５が高速回転する。 Now, set the trip point operating pressure of pressure switch 22.
If it is set to l 1 +L (mmH 2 O), at this point the pressure switch 22 will switch from OFF to ON, the water supply valve will stop supplying water, and the motor 15 will rotate to start washing and dewatering. By the action of the switching clutch, the rotation of the motor 15 is transmitted to the rotor blade 5, and the rotor blade 5 rotates at high speed.

イツチ２２に作用する圧力の変化度合は第２図に
示す通りである。 At this time, due to the centrifugal pumping action of the web blades 6 of the rotor blade 5 described above, the water in the inner tank 2 is sucked through the gap 8 between the inner tank 2 and the rotor blade 5, and at the same time, water is drawn into the water pipe through the water inlet 10. It also sucks the water inside 21,
As a result, the pressure applied to the washing water level setting pressure switch 22 is reduced. The degree of change in the pressure acting on the pressure switch 22 at this time is as shown in FIG.

力が変化している。 As is clear from the experimental results shown in Fig. 2, the change in the working pressure of the pressure switch 22 during washing operation has little to do with the water level (l a - l c ) in the inner tank 2;
Distance L (mm) between the bottom and the lowest point of the water pipe 21
The working pressure changes up to approximately 1/2L (mmH 2 O).

If the design is as follows, the rotary blade 5 will be
It has been found that the suction negative pressure does not cause the washing water level setting pressure switch 22 to malfunction.
一方、洗濯行程が終了した後、タイマーに記憶
された行程に従い、すすぎ行程に移行する。 On the other hand, after the washing process is completed, a rinsing process is started according to the process stored in the timer.
すすぎ行程においては、前述の洗濯行程と同様

の状態では排水弁２３は閉じている。 In the rinsing process, as in the washing process described above, water is supplied from the water supply valve into the inner tank 2, filling the inner tank 2 with water and also flowing into the water reservoir case 18 and the water pipe 21 through the water inlet 10. Filled with water. In this state, the drain valve 23 is closed.
この時、すすぎ水位設定用圧力スイツチ２２′
に作用する圧力は、内槽２内の任意の水位l2（mm）
と、内槽２の底面と通水管２１との距離Ｌ（mm）

となる。 At this time, the rinse water level setting pressure switch 22'
The pressure acting on is the arbitrary water level l 2 (mm) in the inner tank 2.
and the distance L (mm) between the bottom of the inner tank 2 and the water pipe 21
Water pressure L + l 2 (mmH 2 O) obtained by the water height of
becomes.

チ２２′はOFF状態からON状態へ切り換わり、
給水弁は停止し、モータ１５に通電を開始する。 Now, if the trip operating pressure of the rinse water level setting pressure switch 22' is set to l 2 +L (mmH 2 O), at this point the rinse water level setting pressure switch 22' will be switched from the OFF state to the ON state. Instead,
The water supply valve stops, and the motor 15 starts to be energized.

構成してある。 Here, due to the cam configuration of the timer, motor 1
The motor 15 is configured to be energized intermittently and continuously, and the intermittent movement of the motor 15 is controlled by the operation of the washing/spindle switching clutch.
2, and the inner tank 2 is configured to be driven intermittently.
この内槽２の回転運動により内槽２内のすすぎ
水は、遠心力により第３図に示す如き略放物線形
状Ａを呈す。 Due to this rotational movement of the inner tank 2, the rinsing water in the inner tank 2 takes on a substantially parabolic shape A as shown in FIG. 3 due to centrifugal force.
その為、すすぎ水位設定用圧力スイツチ２２′
に作用する水圧は、〔Ｌ＋l2〕（mmH2O）から〔Ｌ
＋l3〕（mmH2O）へと変化し、内槽２の回転速度
が増加していけば、l3＝Ｏすなわち〔Ｌ＋l2〕→
〔Ｌ＋l3〕→〔Ｌ〕（mmH2O）と変化する。 Therefore, the rinse water level setting pressure switch 22'
The water pressure acting on is from [L + l 2 ] (mmH 2 O) to [L
+l 3 ] (mmH 2 O), and as the rotational speed of the inner tank 2 increases, l 3 =O, that is, [L+l 2 ]→
It changes as [L+l 3 ] → [L] (mmH 2 O).
一方、水圧Ｌ（mmH2O）を呈する部分は、内槽

Therefore, even if l 3 =O, a water pressure of L (mmH 2 O) is always applied to the rinse water level setting pressure switch 22'. Therefore, by setting the reset point operating pressure of the rinse water level setting pressure switch 22' below L (mmH 2 O), malfunction of the pressure switch 22' can be prevented.
