Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

A safety system of a water washing machine aims at potential safety hazards caused by continuous rotation of a motor driving roller in the water washing machine. The utility model discloses a solution mode formula inserts the sensor to in inserting the controller of motor with the sensor, the start-up and the stop of controlling the motor through triggering of sensor.

Specifically, referring to fig. 1 to 3, the safety system includes a cabinet 10 of the washing machine, a drum 20 disposed in the cabinet 10, a motor 30 driving the drum 20 to rotate, a sensor 40, and a controller 50 controlling the motor 30 to be started or stopped.

In order to put in and take out articles to be washed, a cabinet door opening 11 is provided on the cabinet 10, and a drum door opening 21 is provided on the drum 20. In particular use, the drum is rotated and the drum door opening 21 is aligned with the cabinet door opening 11, thereby enabling subsequent loading and unloading of the items to be washed.

A sensor 40 is provided to the cabinet door opening 11 for sensing whether a person enters the cabinet door opening 11 in use.

The purpose of the sensor 40 is to sense whether a person or other foreign matter enters the casing 10, and thus any sensor of the prior art that can sense a person or foreign matter can be used.

As shown in fig. 2, the sensor 40 is electrically connected to the controller 50, and when the sensor 40 is triggered, the generated signal is transmitted to the controller 50, so that the controller 50 makes a logic judgment and sends a control signal for turning off the motor 30. The motor 30 stops rotating, so that the damage and the potential safety hazard caused by the rotation of the roller 20 are avoided.

When the washing machine is used in a specific mode, when people are exposed to safety risks and body injuries, the body parts of the people are inserted into the cabinet door opening 11. Accordingly, in some embodiments, a photosensor is employed as the sensor 40. Because the photoelectric sensor can seal the machine shell door opening 11 through the path of light, when foreign matters pass through the machine shell door opening 11, the sensor 40 can be triggered immediately, and the response is sensitive.

Further, an infrared sensor is preferable as the sensor 40. Since infrared sensors have the advantages of being inexpensive and having good stability.

Further, the sensor 40 is disposed on the outer wall of the drum 20 for convenience of arrangement and to secure the sensitivity of the sensor 40.

Further, in the case of using an infrared sensor, the sensor 40 includes a transmitter 41 and a receiver 42, and the transmitter 41 and the receiver 42 are oppositely disposed on two sides of the cabinet door opening 11, respectively, to form a correlation structure. When the transmitter 41 emits infrared rays, it is received by the receiver 42, forming a passage. When an outside person enters the cabinet door opening 11, the infrared ray of the sensor 40 is blocked, and the sensor 40 is triggered.

In some embodiments, the number of the sensors 40 is one in the case of satisfying the effect of use. In other embodiments, the number of sensors 40 may be two, three, four, etc. to provide sufficient coverage of the cabinet door opening 11. As shown in fig. 3, three infrared correlation sensors are disposed on the cabinet door opening 11, and the emitters 41 and the receivers 42 of the three sensors 40 are disposed in a crossed manner, wherein two infrared emission windows are disposed on one emitter 41 in the middle.

Since safety problems for personnel are liable to occur only in the case where the cabinet door opening 11 is opened. Therefore, the sensor 40 is introduced only in the case where the cabinet door opening 11 is opened.

Accordingly, in some embodiments, a cabinet door panel 12 is disposed on the cabinet door opening 11, and a proximity switch 60 is disposed between the cabinet door opening 11 and the cabinet door panel 12. The proximity switch 60 is electrically connected to the controller 50, so that when the proximity switch 60 determines that the cabinet door 12 is opened in the cabinet door opening 11, the controller 50 receives a signal from the sensor 40.

Specifically, when the chassis door 12 is opened in the chassis door opening 11, the proximity switch 60 is triggered, a signal is generated and sent to the controller 50, and a control signal is sent to the sensor 40 through logic judgment of the controller 50, so that the sensor 40 is in a working state, and infrared rays for triggering can be generated.

In practical implementation, the infrared sensor 41 protrudes from the surface of the housing to ensure that the infrared rays emitted from the sensor are far away from the drum 20 as much as possible, thereby achieving the sensing of the foreign matters more early.

Further, the chassis door 12 is rotatably disposed on the chassis 10, and the proximity switch 60 is close to the connection point of the chassis 10 and the chassis door 12, so that the proximity switch 60 can more easily sense the opening of the chassis door 12.

The above examples only represent preferred embodiments of the present invention, which are described in more detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
