Description

Technical Field

[0001] The utility model relates to a washing machine, in particular to a washing machine express sensor. Background Art

[0002] A washing machine is a commonly used household appliance used for automated laundry cleaning. Currently, most washing machines on the market are driven by motors. Some high-end smart washing machines detect their operating speed during operation to ensure that the washing machine can operate at the appropriate motor speed, thereby ensuring cleaning quality. Most washing machines on the market that can detect speed generally use mechanical or electrical sensors to directly detect the drum speed. This detection method has the problems of complex structure, cumbersome production and assembly, and is also very inconvenient for subsequent maintenance. Utility Model Content

[0004] To this end, the present invention is implemented by adopting the following scheme:

[0005] A washing machine quick delivery sensor, characterized in that it includes a snap body, a snap-in slot is provided in the snap-in slot, a quick delivery sensor is mounted in the snap-in slot, a Hall circuit is provided in the quick sensor, the Hall circuit can detect the rotation of the magnetic material on the drum drive motor, and feedback information to the controller based on the rotation of the magnetic material, the snap body is provided with a first positioning plug and a snap arm on both sides of the snap-in slot, the end of the snap arm is provided with a snap protrusion, the quick delivery sensor is connected to the electrical connector via an electric wire, the snap body is also surrounded by a semi-open wire groove, the wire passes through the wire groove, the side wall of the snap-in slot has snap-in blocks arranged at the four corners, the snap-in block is provided with a guide slope at one end close to the opening of the snap-in slot, and the snap-in block is provided with a positioning step at one end close to the inside of the snap-in slot.

[0006] Outward expansion parts are extended on both sides of the buckle body, and the ends of the outward expansion parts are provided with second positioning plug blocks extending downward, and a third positioning plug block is provided with a bent arrangement close to the second positioning plug block.

[0007] The top of the buckle arm passes through the clearance groove on the buckle body and is connected to the arched protrusion, and the two ends of the arched protrusion are connected to the buckle body.

[0008] The buckle body is provided with a positioning pin in the mounting groove, and the positioning pin passes through the positioning hole on the express sensor.

[0009] The wire trough includes a transverse groove portion aligned with the clamping groove, and one side of the transverse groove portion is provided with a vertical groove portion.

[0010] A washing machine speed sensor of the above technical solution can effectively detect the speed of the washing machine. At the same time, it adopts the principle of Hall detection, so it only needs to set up a small-structured speed sensor and configure a Hall circuit. It has a simple structure, reasonable design, and is very convenient to assemble as a whole. It also ensures the stability of the overall position of the sensor during use. At the same time, the snap body installed on the sensor is easy to disassemble and assemble, which facilitates the inspection and replacement of the sensor, and provides a good user experience.

[0017] As shown in the figure, the utility model discloses a washing machine quick delivery sensor, including a snap body 1, which is made of plastic material. A snap-in slot 19 is provided in the snap-in slot 19, in which a quick delivery sensor 14 is mounted. A Hall circuit is provided in the quick delivery sensor 14, which can detect the rotation of the magnetic material on the drum drive motor and feedback information to the controller based on the rotation of the magnetic material. The snap-in slot 19 is provided on both sides of the snap-in slot 19 of the snap-in body 1. A snap-in protrusion 11 is provided at the end of the snap-in arm 12. The quick delivery sensor 14 is connected to the power connector 8 via a wire 6. A semi-open wire groove is also enclosed on the snap-in body 1. The wire 6 passes through the wire trough. The side wall of the card slot 19 has card blocks 17 set at the four corners. The card block 17 is provided with a guide slope 16 at one end near the opening of the card slot 19. The card block 17 is provided with a positioning step 18 at one end near the inside of the card slot 19 for achieving the positioning installation of the sensor. By providing the guide slope 16, the express sensor 14 is guided during the card installation. It is only necessary to press the express sensor 14 so that it passes through the guide slope 16 and is snapped into the card installation part of the card blocks 17 set at the four corners to complete the card installation. Furthermore, the buckle body 1 is extended with an outward expansion portion 2 on both sides. The end of the outward expansion portion 2 has a second positioning plug 5 extending downward. A third positioning plug 10 is bent near the second positioning plug 5. The use of positioning plugs extending in different directions can achieve different directional limits of the buckle body 1 after card installation, further improving the stability of the position of the buckle body 1 after card installation. The top of the snap arm 12 passes through the clearance groove on the snap body 1 and connects to the arched protrusion 3. The two ends of the arched protrusion 3 are connected to the snap body 1. By pressing the arched protrusion 3, the snap arm 12 can be driven to swing, thereby loosening the snap structure. The snap body 1 is provided with a positioning pin 15 in the snap groove 19. The positioning pin 15 passes through the positioning hole on the express sensor 14 to ensure the positioning and installation of the sensor 14. The wire trough includes a horizontal groove portion 9 aligned with the snap groove 19. One side of the horizontal groove portion 9 has a vertical groove portion 7, which can define the routing path of the wire 6, making the routing of the wire more standardized and reasonable.

[0018] The structure of the present invention can effectively realize the detection of the speed of the washing machine. At the same time, it adopts the principle of Hall detection, so it only needs to set up a small-structured speed sensor and configure a Hall circuit. It has a simple structure, reasonable design, and is very convenient to assemble as a whole. It also ensures the stability of the overall position of the sensor during use. At the same time, the snap body for installing the sensor is easy to disassemble and assemble, which facilitates the inspection and replacement of the sensor and provides a good user experience.
