従来の技術
超音波を用いて距離を測定する技術は古くから知られて
おり、洗濯機に超音波を利用し、布量を検出し、給水量
等を自動的に設定する方法は種々提案されている。[Detailed Description of the Invention] Industrial Application Field The present invention sets the optimum water level according to the amount of cloth (fabric type, cloth weight, cloth quality), and automatically sets the washing process based on the water level. 0 Conventional technology The technology of measuring distance using ultrasonic waves has been known for a long time. Various methods have been proposed to set this.
例えば、−例として、洗濯物投入前に超音波により洗濯
槽の底までの距離を測定し、次に洗濯物を投入して洗濯
物の布の上面までの距離を測定し、両者を比較して布量
を判定し給水量等を設定しているものが知られている。For example: - Before adding the laundry, measure the distance to the bottom of the washing tub using ultrasonic waves, then add the laundry and measure the distance to the top of the laundry fabric, and compare the two. There is a known method that determines the amount of cloth and sets the water supply amount, etc.

It is known that the amount of cloth is measured using ultrasonic waves while rotating the dewatering basket.0 Furthermore, in addition to the above-mentioned conventional example, there is a method that uses ultrasonic waves to measure both the amount of cloth and the water level. It has been proposed to include a water spray device that wets the top surface of the laundry to improve the reflection of ultrasonic waves. Furthermore, a water supply amount detection device using ultrasonic waves has also been proposed. This consists of a means for detecting the amount of cloth, a means for detecting that the amount of cloth has been suppressed by the water supply effect, and a means for detecting that the surface of the cloth is pushed up by continuing water supply.

洗濯槽の中心よりずらして設け、バスケットを回転させ
ながら布量を検知する方法では、実際問題として検知時
にバスケットを回転させることは大変困難である。Problems to be Solved by the Invention However, the basic idea of the conventional example is to measure the amount of cloth using ultrasonic waves and determine the water level based on the result. The measurement results vary considerably depending on the quality of the cloth, making it impossible to accurately detect the amount of cloth. In addition, as a method to improve accuracy, the ultrasonic transmitter/receiver is installed offset from the center of the washing tub and the amount of cloth is detected while rotating the basket, but as a practical matter, it is very difficult to rotate the basket at the time of detection.
さらに散水装置により布の上面を押さえたり、給水過程
における布の動きを検知して布量を検知する方法では、
前者は布を均一にするには不充分であり、後者は処理が
複雑であり精度も悪い。Furthermore, methods that detect the amount of cloth by pressing the top surface of the cloth with a water sprinkler or detecting the movement of the cloth during the water supply process,
The former method is insufficient to make the cloth uniform, and the latter method is complicated and has poor accuracy.
すなわち従来の技術では布量に最適な水位を決めたり、
給水後の洗濯行程を設定することがむずかしい。In other words, with conventional technology, it is difficult to determine the optimal water level for the amount of cloth,
It is difficult to set the washing process after water supply.
本発明は上記欠点に鑑みてなされたもので、基本的に布
量そのものを検出するのではなく、水面下に布があるか
どうかを判別し布量に適切な水位を精度良く設定するも
のである。The present invention was made in view of the above drawbacks, and basically does not detect the amount of cloth itself, but rather determines whether there is cloth under the water surface and accurately sets the water level appropriate for the amount of cloth. be.

構成される。Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
Measures the distance to the object to be measured (cloth or water) using ultrasonic waves, calculates and compares the measured data with the set water level, detects the amount of cloth protruding from the water surface, and determines whether the set water level is appropriate. It is something. That is, an ultrasonic transmitter/receiver installed above the washing tub offset from the center of the tub, a water supply means and a water level sensor for supplying water to a predetermined water level, and a cloth and water are stirred when setting the water level, and then a one-way The stirring blade and motor are rotated little by little, and the ultrasonic transmitter/receiver is used to measure the distance to the object while rotating, and these distance data and the set water level are compared and calculated. statistical processing means that calculates the ratio of the amount of cloth that is present, and if the ratio is larger than a predetermined value, the water level is further raised and the above operation is performed again, and this series of operations is repeated until the ratio becomes below the predetermined value. When the water level reaches the optimum water level, the washing process comprises an appropriate water level setting means for setting the set water level as an appropriate water level, and a process parameter setting means for automatically setting part or all of the subsequent washing process based on this suitable water level.

Since the distance is measured by scanning and then the amount of cloth on the water surface is calculated, it is possible to accurately judge whether the set water level at that time is appropriate.
実施例
実施例を説明するまえに、本発明の前提となる基本的な
考え方、すなわち、洗濯物の布量が大部分水面下にある
状態が、その布量に最も適切な水位であるという考え方
について説明する。Embodiments Before explaining the embodiments, let us first explain the basic idea underlying the present invention, that is, the state where most of the amount of laundry is under the water surface is the most appropriate water level for that amount of laundry. I will explain about it.
実験室で数名の女性に洗濯機を使用してもらい、布の重

選択できるようにした。その結果から、個人差は殆んど
なく、布重量と布種類によって水位が決められることが
分った。逆に言えば、ある洗濯物に適切な水位を決める
場合、布の重量のみならず、布の種類（体積。In a laboratory, several women were asked to use a washing machine, and by changing the weight and type of cloth, based on their experience, they determined which water level was the most appropriate for washing their laundry. I was asked to judge. The water level is "small" (241), "low" (32g
), r Medium J (361) and "High" (40e) can now be selected manually. The results showed that there were almost no individual differences, and that the water level was determined by the weight and type of cloth. Conversely, when determining the appropriate water level for a certain type of laundry, consider not only the weight of the fabric, but also the type (volume) of the fabric.
布質）も大きく関与していることが分った。その結果を
第３図に示す。It was found that fabric quality (fabric quality) also plays a major role. The results are shown in FIG.

適としている。On the other hand, in order to consider how the user determines the water level based on the experimental results, we set the conditions of the experimental results (setting the weight, type, and water level), and set the cloth and water. I watched the stirring. As a result, it was found that all water levels were set so that the cloth was almost under the water surface. That is, the user visually judges the amount of cloth, increases the water level one step at a time, stirs the cloth and water appropriately, and sets the water level at the point when most of the cloth is under the water surface to be the optimum level.

とが分った。Although FIG. 3 shows the experimental results for three types of cloth, actual experiments were conducted for each of 12 types of cloth. The optimal water level for each cloth weight is different, but
It was found that all the criteria for determining the water level were based on the above-mentioned concept.
以下、上述した水位設定の基本的な考え方を実現する本

7 is a motor for driving the stirring blade 6 provided at the inner bottom of the stirring blade. 8 is a microcomputer and an interface circuit, and its statistical processing means 9, suitable water level setting means 10, and stroke parameter setting means 11 are realized by microcomputer programs. The above-mentioned stirring blade 6 and motor 7 stir the cloth and water when setting the water level,
After that, it is rotated little by little in one direction. The statistical processing means 9 compares and calculates the distance data obtained by measuring the distance to the object to be measured using the ultrasonic transmitter/receiver 2 and the set water level.
It calculates the ratio of the amount of cloth protruding from the water surface to the water surface. The appropriate water level setting means 10 is a statistical processing means 9.
If the ratio calculated by is larger than the predetermined value, the water level is raised further and the above operation is performed again.This series of operations is repeated, and when the ratio becomes less than the predetermined value, the set water level is increased. is the appropriate water level.

理４）。The operation will be explained based on FIGS. 1 and 2. First, when the laundry (cloth) 12 is loaded and the switch is turned on, water is supplied by the water supply means 4, and the water level sensor 5 indicates "low" (241).
) is set to the water level (process 1). Next, the motor 7 is operated, and the cloth 12 and water 13 are stirred by the stirring blades 6 to blend the cloth and water (processing 2). Next, the motor 7 is stopped, and the ultrasonic transceiver 2 emits ultrasonic waves (25 KHz), which are reflected by the cloth 12 or water 13 and transmitted to the ultrasonic transceiver 2.
The time it takes for the object to return to the object is measured, and the distance to the object is measured using the ultrasonic transmitting/receiving circuit and the distance measuring circuit 3. The results are sent to the statistical processing means 9 of the microcomputer and interface circuit 8. Next, the motor 7 is rotated little by little in one direction, and each time the distance between the objects to be measured (cloth 12 and water 13) i is measured using ultrasonic waves, and the distance is sent to the statistical processing means 9 (processing 3). This measurement is performed 10 times (processing 4).

いる。In addition, the rotation angle of the stirring blade 6 is 10 times, just 1 cloth.
2 and water 13 make one rotation. That is, the upper surface inside the washing tub 1 is scanned over the entire surface and the distance is measured using ultrasonic waves. Note that for one measurement, ultrasonic waves are transmitted and received multiple times (10 times) to improve the accuracy of one measurement.
統計処理手段９に送られた各回の距離データは、それぞ

ている。The distance data sent to the statistical processing means 9 each time is "low" water level data (each water level has already been transmitted to the ultrasonic transceiver 2).
It is known as the distance from and stored in memory. ), and calculate the data smaller than the "low" water level, that is, the ratio of the amount of cloth protruding above the water surface (processing 5
). Note that the water level data used as a comparison standard is set with a wide range in consideration of sensor accuracy and variations in ultrasonic transmitter and receiver.

The above-described operation is then repeated until the ratio of the amount of cloth protruding above the water surface becomes smaller than a predetermined value. When the ratio becomes smaller, it is determined that the water level is optimal (process 7), and based on the result, the process parameter setting means 11 sets the time parameters for the subsequent process, for example, the washing process. Since the amount of cloth can be detected indirectly in the form of water level, it is only necessary to set appropriate parameters (water flow, number of rinses, spin-drying time, etc.).
なお、実施例では、「高」水位までしかないので、「中
」水位において、水面上の布量比率が所定の値より大き
いと判断すると「高」水位における上記動作は行わず、
自動的に「高」と判断する（処理８）ことは言うまでも
ない。In addition, in the embodiment, since the water level is only up to the "high" water level, if it is determined that the cloth amount ratio on the water surface is larger than a predetermined value at the "medium" water level, the above operation at the "high" water level is not performed.
Needless to say, it is automatically determined as "high" (processing 8).

ることができる。Effects of the Invention The present invention is based on a new idea of setting the optimum water level by determining whether the cloth is below the water surface, rather than detecting the amount of cloth itself. It is possible to accurately set the water level suitable for the amount of cloth without being affected, and the configuration is simple and has great practical value. Also, knowing the optimal water level is indirectly detecting the amount of cloth.
Parameters for processes after washing can be set to values appropriate for the amount of cloth.
