For those skilled in the art, the specific meanings of the above terms in the present invention can be understood on a case-by-case basis.

A washing machine in accordance with an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 5, a washing machine according to an embodiment of the present invention includes a case 10, a tub 20 provided in the case 10, and a boom assembly 30, which is disposed adjacent to the periphery of the top of the case 10. The socket 101 is recessed downwardly, and optionally, the socket 101 is formed on the casing 10. The boom assembly is located in the cabinet. The photoelectric load cell assembly 40 is coupled to the boom assembly 30 and is hingedly coupled to the socket 101 on the housing 10 by the boom assembly 30.

Thus, according to the washing machine of the present invention, by setting the photoelectric load cell assembly 40, the weight variation in the tub 20 can be accurately weighed, thereby ensuring the washing performance.

As shown in FIG. 1 to FIG. 5, the photoelectric weighing sensor assembly 40 of the washing machine according to the embodiment of the present invention includes: a lower casing 401, an upper casing 402, a light emitting end 403, a light receiving end 404, and a light reflecting platform. 405 and first elastic member 406. Specifically, the upper casing 402 is connected to the lower casing 401 so as to be movable up and down. The light emitting end 403 and the light receiving end 404 are spaced apart from each other on the lower surface of the upper casing 402. The light reflecting platform 405 is disposed on the upper surface of the lower casing 401 and corresponds to the lower side of the light emitting end 403 and the light receiving end 404. That is, a light beam is emitted from the light emitting end 403 and irradiated onto the light reflecting platform 406, and the light reflecting platform 406 emits the light beam and is received by the light receiving end 404. The change in the spacing between the lower casing 401 and the upper casing 402 is detected by the emission-reflection-receiving of the light beam.

The first elastic member 406 is disposed between the lower case 401 and the upper case 402 to constantly push the upper case 402 away from the lower case 401. The first elastic member 406 may be a first spring or a first elastic piece. Preferably, the first spring is a linear spring having a constant spring constant k.

Therefore, when the weight in the barrel 20 changes, the first elastic member 406 of the photoelectric weighing sensor assembly is deformed by force, and the spacing between the upper casing and the lower casing is changed, and the light is emitted. The end, the light receiving end and the light reflecting platform detect the spacing between the upper casing and the lower casing, and then according to the preset spacing change table and the weight change table, accurate weighing can be achieved.

That is, when the weight of the clothes and water in the tub 20 is small, the amount of compression deformation of the first elastic member 406 of the photoelectric weighing sensor assembly is small. The compression deformation of the first elastic member 406 causes a change in the distance d between the light reflecting platform 405 and the light emitting end 403 and the light receiving end 404. The light receiving end 404 converts the received optical signal into an electrical signal having a correspondence (preferably a linear correspondence) with the pitch d. 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 weight of the washing machine by a predetermined program (for example, a table corresponding to the change between the preset spacing d and the weight). Optional The upper surface is a spherical or curved surface. Preferably, the lower surface of the lower casing 402 is configured as a spherical or curved surface to be adapted to cooperate with the shape of the socket to achieve spherical articulation of the photoelectric load cell assembly and the socket, thereby ensuring that the washing machine is even in operation It can also be accurately weighed.

As shown in FIG. 3, in accordance with an embodiment of the present invention, the lower housing 401 is inserted into the upper housing 402. Advantageously, the lower casing 401 has a first flange 4011 on its upper circumference, and a lower edge of the upper casing 402 has a second flange 4021 adapted to the first flange 4011. Thereby, the lower case 401 and the upper case 402 can be restricted.

According to some embodiments of the present invention, as shown in FIG. 4, the boom assembly 30 includes: a boom 301 and a second elastic member 302. A second elastic member 301, such as a second spring, is provided at the lower end of the boom 301. And the photoelectric weighing sensor assembly 40 of the washing machine is disposed at the upper end of the boom 301. Advantageously, the upper housing 402 is fixed to the upper end of the boom 301 and the lower housing 401 is movably coupled to the upper end of the boom 301.

As shown in Figs. 1 to 3 and 5, preferably, the second elastic member 302 is coupled to the tub 20 and the photoelectric load cell assembly 40 is coupled to the housing 10.

In other words, when the weight in the tub 20 changes (for example, adding laundry and water), the weight change is transmitted to the boom 301 through the second elastic member 302, and finally transmitted to the washing machine for photoelectric weighing induction. The device assembly, as described above, can detect the weight change of the barrel 20 by detecting the change of the distance d between the lower casing 401 and the upper casing 402, and can accurately weigh the washing machine based on accurate weighing. The washing machine can adjust the performance indicators more precisely.
