As shown in fig. 1, the vibration detecting apparatus includes a housing 10, a contact detecting element 20, and a triggering element 30, the housing 10 having a housing chamber 11, the housing chamber 11 including a lateral chamber section 111 and a longitudinal chamber section 112 communicating with each other; the number of the contact detecting elements 20 is two, the two contact detecting elements 20 are both disposed on the housing 10, the contact detecting ends 201 of the two contact detecting elements respectively extend into the transverse cavity section 111 and the longitudinal cavity section 112, the trigger element 30 is movably disposed in the accommodating cavity 11, the trigger element 30 is configured to touch the two contact detecting ends 201, and when the contact detecting ends 201 are touched, the contact detecting elements 20 send out an on-off signal including a vibration state of the washing machine in a horizontal direction and/or a vertical direction.
Through carrying out configuration optimization to washing machine's vibration detection device, realized utilizing single vibration detection device just can monitor washing machine at the vibration of horizontal direction and vertical direction simultaneously, guaranteed washing machine to its self vibration detection accuracy nature of judging, and when being favorable to improving washing machine's intelligent control degree, still simplified washing machine's assembly complexity, reduced washing machine's whole processing manufacturing cost, promoted washing machine's economic nature and practicality.
Specifically, the position of the trigger element 30 changes in the accommodating cavity 11 along with the vibration of the washing machine, and when the washing machine vibrates in the horizontal direction, the trigger element 30 moves in the transverse cavity section 111 and touches the contact detection end 201 of the contact detection element 20 located in the transverse cavity section 111, so that the contact detection element 20 sends out an on-off signal containing the vibration information of the washing machine in the horizontal direction; when the washing machine vibrates in the vertical direction, the trigger element 30 moves in the longitudinal cavity section 112 to touch the contact detection end 201 of the contact detection element 20 located in the longitudinal cavity section 112, so that the contact detection element 20 can send out an on-off signal containing vibration information of the washing machine in the vertical direction; therefore, the vibration state of the washing machine can be accurately known, and the working mode of the washing machine can be further adjusted conveniently.
The vibration detection device provided by the application further has the characteristics of simplicity in assembly, saving of assembly space, low cost, high sensitivity and high universality.
As shown in fig. 1, the receiving chamber 11 is L-shaped in order to ensure that the movement of the triggering element 30 in the receiving chamber 11 is always effective. I.e., the leading end of the lateral cavity section 111 is connected to the trailing end of the longitudinal cavity section 112.
In the present embodiment, the contact-detecting elements 20 are contact switches, and the two contact-detecting elements 20 include a lateral contact switch 21 and a longitudinal contact switch 22, wherein the contact-detecting end 201 of the lateral contact switch 21 is located at the end of the lateral cavity section 111, and the contact-detecting end 201 of the longitudinal contact switch 22 is located at the end of the longitudinal cavity section 112 far from the lateral cavity section 111. Thus, the trigger element 30 can move freely in the L-shaped accommodating cavity 11 under the driving of the vibration of the washing machine, two contact detection ends 201 are respectively arranged at two ends of the L-shaped accommodating cavity 11, namely, the contact detection end 201 of the transverse contact switch 21 is arranged in the transverse cavity section 111, the contact detection end 201 of the longitudinal contact switch 22 is arranged in the longitudinal cavity section 112, and the two contact detection ends 201 are both used for being in touch fit with the trigger element 30, so that the undesirable vibration of the washing machine in the vertical direction and the horizontal direction can be detected simultaneously, and the monitoring effect is obvious. Meanwhile, the vibration of the washing machine in the vertical direction and the horizontal direction can be monitored simultaneously by using a single vibration detection device, so that the trouble caused by installation of a plurality of vibration detection devices can be avoided, and the assembly is more convenient and quicker.
As shown in fig. 1, the bottom wall surface of the lateral cavity section 111 extends obliquely upward from the longitudinal cavity section 112 side to the lateral contact switch 21 side. In this way, when the vibration amplitude of the washing machine is not large or the washing machine is in a stopped state, it is ensured that the trigger element 30 is located at the corner point of the left end of the cavity bottom wall surface of the lateral cavity section 111 without contacting any one of the contact detecting terminals 201.
Optionally, the trigger element 30 rolls within the lateral cavity section 111 and within the longitudinal cavity section 112. In this way, the reliability of the movement of the triggering element 30 under the vibrations of the washing machine is facilitated.
Optionally, the trigger element 30 is a sphere, ellipsoid or cylinder.
As shown in fig. 1, the cavity bottom wall surface of the lateral cavity section 111 and the cavity side wall surface of the longitudinal cavity section 112 are both smooth surfaces, and the junction between the two is in smooth transition. Therefore, the triggering element 30 can not only be prevented from being influenced by excessive resistance when rolling in the transverse cavity section 111 and the longitudinal cavity section 112 to be effectively contacted with the contact detection end 201, but also the triggering element 30 can be favorably and stably switched in the movement direction between the transverse cavity section 111 and the longitudinal cavity section 112 along with different types of vibration of the washing machine.
As shown in fig. 1, the vibration detecting apparatus further includes a buffer element 40, the buffer element 40 is disposed in the lateral cavity section 111 and/or the longitudinal cavity section 112, a first end of the buffer element 40 is connected to a wall surface of the accommodating chamber 11 at the position of the contact detecting element 20, a second end of the buffer element 40 is a buffer end 41, and the buffer end 41 protrudes into the accommodating chamber 11 and passes over a contact detecting end 201 of the contact detecting element 20. In the illustrated embodiment of the present application, only one buffering element 40 is disposed in the lateral cavity section 111, and the buffering element 40 is disposed to avoid a situation that the triggering element 30 continuously touches the contact detection end 201 to generate frequent on-off signals due to excessive vibration of the washing machine in the horizontal direction; the buffer member 40 serves to limit the trigger member 30 and protect the touch sensing member 20; in this embodiment, the trigger element 30 contacts the buffer element 40 before contacting the contact detection end 201, and the application should avoid that the trigger element 30 cannot contact the contact detection end 201 due to the over-rigidity of the buffer element 40.
It should be noted that the vibration detection device further includes a control unit, and the control unit is configured to receive an on-off signal sent by the touch detection element 20 when touched by the trigger element 30, and adjust an operation mode of the washing machine according to the on-off signal. Therefore, the condition that the continuous vibration of the washing machine is overlarge can be effectively prevented, and the working stability and the use safety of the washing machine are ensured.
As shown in fig. 1, in order to facilitate maintenance of the components in the housing 10, the housing 10 includes a base plate 12 and a housing cover 13, and the housing cover 13 is detachably mounted on the base plate 12 by fasteners 50. Of course, the two can also be clamped or bonded. The bottom plate 12 may be detachably connected to the body of the washing machine, or may be integrally formed with the body of the washing machine.
The method for detecting and controlling the vibration of the washing machine is described below, wherein the vibration detection device is used for detecting and controlling the vibration of the washing machine; the control unit judges the vibration direction of the washing machine through on-off signals sent by two contact type detection elements 20 of the vibration detection device respectively arranged in the transverse cavity section 111 and the longitudinal cavity section 112, and judges the vibration level of the washing machine according to the frequency of the on-off signals; the control unit adjusts an operation mode of the washing machine according to a vibration level of the washing machine.
It should be noted that when the triggering element 30 moves in the transverse cavity segment 111 or the longitudinal cavity segment 112 and touches the contact detection end 201 of the touch detection element 20, the touch detection element 20 sends an on/off signal.
It should be noted that the operation modes of the washing machine include: the system comprises an alarm working mode, a constant speed bucket scattering working mode, a water inlet bucket scattering working mode, a speed reduction bucket scattering working mode and a shutdown mode. Thus, it is possible to effectively monitor the bad vibration of the washing machine during the dehydration, washing and rinsing processes.
As shown in fig. 2, since the drum-hitting, the displacement phenomenon, and the hitting sound of the washing machine mostly come from the vibration in the horizontal direction, the harm of the vibration in the horizontal direction to the washing machine is relatively greater than the vibration in the vertical direction; therefore, the control method is more rigorous to control the vibration frequency in the horizontal direction, when the vibration frequency in the horizontal direction is 1-3Hz, a warning is sent out and the water bucket is decelerated to disperse, and when the vibration frequency is more than 3Hz, the shutdown treatment is carried out; when the vibration frequency in the vertical direction is 1-3Hz, the rotating speed is stopped, only uniform bucket dispersion is carried out, when the vibration frequency in the vertical direction is 4-10Hz, a warning is given out, the water bucket dispersion is decelerated, and when the vibration frequency in the vertical direction is above 10Hz, shutdown treatment is carried out, so that more proper and safe protection is provided for the washing machine.
