The elastic modulus of the second elastic member is Κ2, and the length of the second elastic member is greater than The length of an elastic member, and the elastic modulus Κ2 of the second elastic member is smaller than the elastic modulus K1 of the first elastic member.
当根据本发明实施例的用于洗衣机的光电称重传感器用于称重时， 第二弹性件 331 首 先发生压缩形变， 以感知负重。 当负重变大， 第一弹性件 330和第二弹性件 331—起发生 压缩形变， 以感知负重。  When the photoelectric load cell for a washing machine according to an embodiment of the present invention is used for weighing, the second elastic member 331 first undergoes compression deformation to sense the load. When the load is increased, the first elastic member 330 and the second elastic member 331 are compressed and deformed to sense the load.
根据本发明实施例的用于洗衣机的光电称重传感器， 所述第一弹性件设在所述下壳体 和所述上壳体之间， 所述第二弹性件设在所述下壳体和所述上壳体之间以常推动所述上壳 体远离所述下壳体， 对于负载较轻时， 利用第二弹性件即长弹簧的变形量来感知负重， 而 对于负重较重， 则可以利用第二弹性件的变形量和第一弹性件的变形量来感知负重， 提高 了称重精度。  According to an embodiment of the present invention, an optical load cell for a washing machine, the first elastic member is disposed between the lower casing and the upper casing, and the second elastic member is disposed at the lower casing And the upper casing is constantly pushed away from the lower casing, and when the load is light, the load is sensed by the deformation amount of the second elastic member, that is, the long spring, and the load is heavy, Then, the amount of deformation of the second elastic member and the amount of deformation of the first elastic member can be utilized to sense the load, and the weighing accuracy is improved.
换言之， 根据本发明实施例的用于洗衣机的光电称重传感器， 重量有变化时， 第二弹 性件首先受力发生形变， 进而会使上壳体和下壳体之间的间距发生变化； 当重量继续加重 时， 第一弹性件也随之受力发生形变。 通过光发射端、 光接收端和光反射平台来检测上壳 体和下壳体之间的间距， 然后根据预设的间距变化与重量之间的变化对应表， 可以实现精 准称重。 也即是说， 当根据本发明实施例的用于洗衣机的光电称重传感器安装在洗衣机上时， 洗涤桶内衣服和水重量较小时， 第二弹性件 331首先发生压缩变形。 第二弹性件 331的压 缩变形导致光反射平台 360与光发射端 340及光接收端 350的间距 d产生变化。 光接收端 350将接收的光信号转化为电信号， 该信号与间距 d成对应关系 （优选为线性对应关系）。 该信号可以准确反映洗衣机洗涤桶重量以及位移的变化。 转化后的电信号传输给洗衣机控 制器， 控制器通过预定的程序（例如， 预设间距 d的变化与重量之间的变化对应表）， 可以 实现洗衣机的桶体较轻重量的精准称重。 而当洗涤桶内衣服和水重量较大时， 第一弹性件 330也随之发生压缩形变， 光反射平台 360与光发射端 340及光接收端 350的间距 d进一 步发生变化。 如上所述， 可以实现洗衣机的桶体较轻重量的精准称重。 In other words, according to the photoelectric load cell for a washing machine according to the embodiment of the present invention, when the weight is changed, the second elastic member is first deformed by force, thereby changing the spacing between the upper casing and the lower casing; When the weight continues to increase, the first elastic member is also deformed by the force. The distance between the upper casing and the lower casing is detected by the light emitting end, the light receiving end, and the light reflecting platform, and then the table corresponding to the change between the preset spacing change and the weight can be realized. Quasi-weighing. That is, when the photoelectric load cell for a washing machine according to the embodiment of the present invention is mounted on the washing machine, the second elastic member 331 is first subjected to compression deformation when the weight of the clothes and water in the washing tub is small. The compression deformation of the second elastic member 331 causes a change in the distance d between the light reflecting platform 360 and the light emitting end 340 and the light receiving end 350. The light receiving end 350 converts the received optical signal into an electrical signal, which is in a correspondence with the spacing d (preferably a linear correspondence). This signal accurately reflects the change in the weight and displacement of the washing tub. The converted electrical signal is transmitted to the washing machine controller, and the controller can accurately weigh the barrel of the washing machine by a predetermined program (for example, a table corresponding to the change between the preset spacing d and the weight). When the weight of the clothes and the water in the washing tub is large, the first elastic member 330 is also compressed and deformed, and the distance d between the light reflecting platform 360 and the light emitting end 340 and the light receiving end 350 is further changed. As described above, accurate weighing of the drum body of the washing machine can be achieved.
有利地，根据本发明的一个示例，下壳体 320的上表面上设有向上延伸的下安装台 322。 上壳体 310的下表面上设有向下延伸且与下安装台 322上下相对的上安装台 311。 第一弹 性件 330间隔设在上安装台 311的下表面与下安装台 322的上表面之间。 第二弹性件 331 的内周面分别与上安装台 311的外周面和下安装台 322的内周面接触。  Advantageously, according to an example of the present invention, the upper surface of the lower casing 320 is provided with an upwardly extending lower mounting platform 322. The upper surface of the upper casing 310 is provided with an upper mounting table 311 extending downward and opposed to the lower mounting table 322. The first elastic member 330 is spaced between the lower surface of the upper mounting table 311 and the upper surface of the lower mounting table 322. The inner peripheral surface of the second elastic member 331 is in contact with the outer peripheral surface of the upper mounting base 311 and the inner peripheral surface of the lower mounting base 322, respectively.
进一步地，下安装台 322的上表面上还设有向上延伸的凸缘 323。第一弹性件 330的外 周面与凸缘 232的内周面接触。 由此， 可以对第一弹性件 330进行定位， 且还可以分隔第 一弹性件 330和第二弹性件 331。  Further, the upper surface of the lower mounting table 322 is further provided with an upwardly extending flange 323. The outer peripheral surface of the first elastic member 330 is in contact with the inner peripheral surface of the flange 232. Thereby, the first elastic member 330 can be positioned, and the first elastic member 330 and the second elastic member 331 can also be separated.
有利地， 根据本发明的一个示例， 第一弹性件 330为第一弹簧， 第二弹性件 331为第 二弹簧。 进一步地， 所述第一弹簧的弹性系数 K1大于所述第二弹簧的弹性系数 K2。  Advantageously, according to one example of the invention, the first resilient member 330 is a first spring and the second resilient member 331 is a second spring. Further, the spring coefficient K1 of the first spring is greater than the spring constant K2 of the second spring.

The linear spring, that is, two springs of different lengths are connected in series on the boom. The second elastic member 331 has a small value of the long spring Κ2, and the first elastic member 330, that is, the short spring K1 has a large value, and the long spring is deformed at a small load, and the signal output of the sensor is related to the deformation displacement of the long spring. When the load of the cloth and water in the bucket is large enough, the short springs are also compressed, and the long spring short springs are collectively stressed. The signal output of the sensor is related to the common displacement of the two springs. Therefore, in the load-bearing range, the load can be accurately sensed from light to heavy, and the load weighing accuracy is improved.
