Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of washing equipment, and particularly provides a monitoring method for a running state of washing equipment and the washing equipment. BACKGROUND

[0002] With the improvement of people's living standards, washing machines have become one of the main household appliances in people's daily life. If the washing machine feet are not flat during the running process, it will affect the washing effect of clothes, increase the noise during the running of the equipment, and even cause the washing machine to displace, affecting the user experience. Moreover, with the popularity of embedded washing machines, the adjustment of the machine feet is also increasing, which increases the risk of displacement.

[0003] To solve the above problems, a method for monitoring washing machine displacement data is provided in the prior art. The three-axis acceleration data of the washing machine outer drum is collected by a MEMS sensor, and then different filter coefficients and gain filters are selected according to the rotational speed of the washing machine to obtain high-precision washing machine displacement data. The washing machine displacement data is transmitted to the serial port in real time. When the serial port receives the real-time rotational speed of the washing machine, it will send the current displacement of the washing machine to the controller of the washing machine in real time to control the rotational speed of the washing machine motor, thereby avoiding further displacement of the washing machine. However, this monitoring method cannot fundamentally solve the problem of washing machine displacement, and cannot avoid the noise generated by washing machine vibration.

[0004] Therefore, there is a need for a new monitoring method for a running state of washing equipment to solve the existing problems. SUMMARY

[0010] In the specific embodiment of the method for monitoring the running state of the washing device, the step of determining whether the washing device is horizontal based on the vibration data of the first foot, the second foot, the third foot and the fourth foot further comprises: obtaining a difference in vibration amplitude of the first foot, the second foot, the third foot and the fourth foot in the vertical direction based on the vibration data of the first foot, the second foot, the third foot and the fourth foot; determining whether the difference in vibration amplitude of the first foot, the second foot, the third foot and the fourth foot in the vertical direction is greater than or equal to a first preset amplitude value; and if the difference in vibration amplitude of any two of the first foot, the second foot, the third foot and the fourth foot in the vertical direction is greater than or equal to the first preset amplitude value, the washing device is not horizontal.

[0011] In the specific embodiment of the method for monitoring the running state of the washing appliance, the step of "selectively adjusting the height of the first foot, the second foot, the third foot and the fourth foot based on the judgment result" further comprises: if the washing appliance is not horizontal, then adjusting the height of the first foot, the second foot, the third foot and the fourth foot based on the difference of the vibration amplitude of the first foot, the second foot, the third foot and the fourth foot in the vertical direction.

[0012] In the specific embodiment of the method for monitoring the running state of the washing appliance, the method further comprises: obtaining the amplitude of the first foot and the second foot in the horizontal direction; judging whether the amplitude of the first foot and / or the second foot in the horizontal direction is greater than or equal to a second preset amplitude; if the amplitude of the first foot and / or the second foot in the horizontal direction is greater than or equal to the second preset amplitude, then the washing appliance is in an eccentric running state.

[0013] In the specific embodiment of the method for monitoring the running state of the washing appliance, the step of "if the amplitude of the first foot and / or the second foot in the horizontal direction is greater than or equal to the second preset amplitude, then the washing appliance is in an eccentric running state" further comprises: controlling the washing appliance to stop running, and dispersing the washing articles inside the washing appliance to make them uniformly distributed.

[0016] The technical effect of the present application is that during the operation of the washing equipment, the washing equipment can monitor the vibration data such as the amplitude and vibration frequency at the first foot and the second foot, determine whether the first foot and the second foot are in a horizontal position based on the vibration data at the first foot and the second foot, and adjust the height of the first foot and the second foot if the first foot and the second foot are not in a horizontal position. Specifically, when the first foot and the second foot are found to have inconsistent vibration amplitudes according to the first vibration sensor and the second vibration sensor, it indicates that the first foot and the second foot are not horizontal at this time. The difference between the vibration amplitudes of the first foot and the second foot can be calculated to obtain the distance of the first foot and the second foot in the vertical direction, so that the adjusting device can be controlled to adjust the first foot and the second foot to move to the corresponding height, so that the first foot and the second foot can be in a horizontal position, thereby avoiding the problem that the existing washing equipment cannot timely discover and solve the problem when the foot is not flat, resulting in shaking noise and even displacement of the washing equipment during operation.

[0025] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will appreciate that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application occasions. For example, although the description is described by taking a drum washing machine as an example, the monitoring method of the running state of the washing equipment of the present application can obviously also be applied to various washing equipment as long as the washing equipment has a foot and may shake during operation.

[0026] First, the existing drum washing machine is described. In order to save installation space, the existing drum washing machine usually adopts an embedded installation method, but if the washing machine is not installed in place, the foot is not flat, and the washing machine will shake during operation, and even if the shaking amplitude is too large, the washing machine will also displace, which has a certain safety risk. And due to the embedded installation method, it is not convenient to adjust the foot of the washing machine, so how to monitor the running state of the washing machine during operation and discover and solve the problem in time when the washing machine shakes become the key to the technical breakthrough in the field. The prior art proposes a method for monitoring washing machine displacement data, collecting three-axis acceleration data of the outer barrel of the washing machine through a MEMS sensor, then selecting different filter coefficients and gain filters according to the rotational speed of the washing machine, obtaining high-precision washing machine displacement data, and transmitting the washing machine displacement data to the serial port in real time. When the serial port receives the real-time rotational speed of the washing machine, it will send the current displacement of the washing machine to the controller of the washing machine in real time to control the rotational speed of the washing machine motor, thereby avoiding further displacement of the washing machine. However, this can only temporarily suspend the shaking of the washing machine, and cannot fundamentally solve the problem of shaking of the washing machine during operation, therefore, the present application proposes the following embodiments.

[0027] Embodiment one,

[0028] To solve the above problems, the washing machine of the present application comprises a first foot and a second foot with adjustable height, and a first vibration sensor and a second vibration sensor are arranged on the first foot and the second foot respectively, as shown in Figures 1-3 The monitoring method comprises:

[0029] S1, controlling the first vibration sensor to obtain vibration data of the first foot;

[0030] S2, controlling the second vibration sensor to obtain vibration data of the second foot;

[0031] S3, judging whether the first foot and the second foot are horizontal based on the vibration data of the first foot and the second foot;

[0032] S4, selectively adjusting the height of the first foot and the second foot based on the judgment result.

[0033] In the above steps, step S3 further comprises:

[0034] S31, obtaining a difference of vibration amplitudes of the first foot and the second foot in the vertical direction based on the vibration data of the first foot and the second foot;

[0035] S32, judging whether the difference of vibration amplitudes of the first foot and the second foot in the vertical direction is greater than or equal to a first preset amplitude value;

[0036] S33, if the difference of vibration amplitudes of the first foot and the second foot in the vertical direction is greater than or equal to the first preset amplitude value, the first foot and the second foot are not horizontal.

[0037] Step S4 further comprises:

[0038] S41, if the first foot and the second foot are not horizontal, adjusting the height of the first foot or the second foot based on the difference of vibration amplitudes of the first foot and the second foot in the vertical direction to make the first foot and the second foot horizontal.

[0039] In the operation of the washing machine of the present application, the vibration data such as the amplitude and the frequency of the first foot and the second foot are obtained by the first vibration sensor and the second vibration sensor, and then the difference of vibration amplitudes of the first foot and the second foot in the vertical direction is calculated based on the vibration data of the first foot and the second foot. If the difference of vibration amplitudes is greater than or equal to the first preset amplitude value, it indicates that the first foot and the second foot are not horizontal. The distance of the first foot and the second foot in the vertical direction can be obtained by calculating the difference of vibration amplitudes of the first foot and the second foot, and then the height of the foot can be adjusted by the foot height adjusting device based on the distance of the first foot and the second foot in the vertical direction to make the first foot and the second foot horizontal, thereby avoiding the problem that the existing washing equipment cannot timely find and solve the problem when the foot is not flat, resulting in shaking noise and even displacement during operation. Preferably, the height of the foot with high vertical height is adjusted to the height of the foot with low vertical height.

[0040] Example two,

[0041] The scheme of adjusting the height of the feet according to the difference of the amplitudes between the two feet of the washing machine is simply described in the first embodiment. Considering the actual situation, the washing machine usually includes four feet, and the four feet can not be in the same horizontal plane. The present embodiment is proposed for this situation. In the present embodiment, the washing equipment further includes a third height-adjustable foot and a fourth height-adjustable foot. Third and fourth vibration sensors are arranged on the third and fourth feet respectively, as shown in Figures 4-6 The monitoring method further includes:

[0042] S5, controlling the third vibration sensor to obtain vibration data of the third foot;

[0043] S6, controlling the fourth vibration sensor to obtain vibration data of the fourth foot;

[0044] S7, judging whether the washing equipment is horizontal based on the vibration data of the first foot, the second foot, the third foot and the fourth foot.

[0045] S8, selectively adjusting the height of the first foot, the second foot, the third foot and the fourth foot based on the judgment result.

[0046] In the above steps, step S7 further includes:

[0047] S71, obtaining the difference of the amplitudes of the first foot, the second foot, the third foot and the fourth foot in the vertical direction based on the vibration data of the first foot, the second foot, the third foot and the fourth foot.

[0048] S72, judging whether the difference of the amplitudes of the first foot, the second foot, the third foot and the fourth foot in the vertical direction is greater than or equal to a first preset amplitude value.

[0049] S73, if the difference of the amplitudes of any two of the first foot, the second foot, the third foot and the fourth foot in the vertical direction is greater than or equal to the first preset amplitude value, the washing equipment is not horizontal.

[0050] Step S8 further includes:

[0051] S81, if the washing equipment is not horizontal, adjusting the height of the first foot, the second foot, the third foot and the fourth foot based on the difference of the amplitudes of the first foot, the second foot, the third foot and the fourth foot in the vertical direction.

[0052] Different from the previous embodiment, in this embodiment, the vibration data of the four feet of the washing machine are acquired simultaneously, and whether the difference between the amplitudes of the four feet of the washing machine in the vertical direction is greater than or equal to a first preset amplitude value is determined to determine whether the four feet (i.e. the washing machine) are in a horizontal position. If the washing machine is not horizontal, the heights of the first foot, the second foot, the third foot and the fourth foot are adjusted based on the difference between the amplitudes of the first foot, the second foot, the third foot and the fourth foot in the vertical direction, so that the washing machine is finally in a horizontal position. It is worth mentioning that when adjusting the height of the foot of the washing machine, the vertical height of the high foot and the vertical height of the low foot are preferably adjusted to the height of the foot with the vertical height in the middle, and during the adjustment of the foot, the low foot is preferably adjusted first to avoid the washing machine from tilting during the adjustment.

[0053] Embodiment three,

[0054] In addition to the vibration in the vertical direction, the washing machine also vibrates in the horizontal direction during operation. The vibration in the horizontal direction may be related to whether the distribution of clothes in the rotating drum is uniform. If the vibration in the horizontal direction is too large, it may cause the washing machine to move in the horizontal direction. Therefore, the present embodiment is proposed. In the present embodiment, as shown in Figure 7 The monitoring method further comprises:

[0055] SA, acquiring the amplitude of the first foot and the second foot in the horizontal direction;

[0056] SB, determining whether the amplitude of the first foot and / or the second foot in the horizontal direction is greater than or equal to a second preset amplitude value;

[0057] SC, if the amplitude of the first foot and / or the second foot in the horizontal direction is greater than or equal to the second preset amplitude value, the washing equipment is in an eccentric running state.

[0058] In the above steps, after step SC, the method further comprises:

[0059] SD, controlling the washing equipment to stop running, and scattering the washing articles in the washing equipment to make them uniformly distributed.

[0060] The way of scattering the washing articles can be to set a scattering device in the washing equipment and control the scattering device to scatter the washing articles, or to send a prompt information of “scattering the washing articles” to the user.

[0061] In the case of using the above-mentioned embodiments, whether the washing machine is in the eccentric running state can be judged according to the amplitude of the first foot and the second foot in the horizontal direction and the size of the second preset amplitude value, if the washing machine is in the eccentric running state, the washing machine is controlled to stop running, and the dispersing device is controlled to disperse the clothes in the washing machine, or a prompt message of "dispersing the washing materials" is sent to the user's mobile terminal through the display screen, reminding the user to disperse the eccentrically distributed clothes, so that the case that the washing machine shakes too much or even displaces in the horizontal direction due to the eccentric distribution of the clothes in the washing machine is avoided.

[0062] In addition, the present application also provides a washing equipment, which comprises a first foot, a second foot, a third foot and a fourth foot with adjustable height, and first, second, third and fourth vibration sensors are arranged on the first, second, third and fourth feet respectively, and the washing equipment further comprises a dispersing device, a display screen for interacting with a user and a controller, the first, second, third and fourth vibration sensors, the dispersing device, the display screen and the controller are in communication connection, and the washing equipment can execute any one of the monitoring methods for the running state of the washing equipment in the above technical solutions.

[0063] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present application and are not intended to limit the protection scope of the present application, and those skilled in the art can adjust the above-mentioned structure without departing from the principles of the present application, so that the present application can be applied to more specific application scenarios.

[0064] Those skilled in the art can understand that the above-mentioned washing machine also comprises some other known structures, such as a processor, a controller, a memory and the like, wherein the memory includes but is not limited to a random access memory, a flash memory, a read-only memory, a programmable read-only memory, a volatile memory, a non-volatile memory, a serial memory, a parallel memory or a register and the like, and the processor includes but is not limited to a CPLD / FPGA, a DSP, an ARM processor, a MIPS processor and the like. In order not to unnecessarily obscure the embodiments of the present disclosure, these known structures are not shown in the drawings.

[0065] Although the steps in the above-mentioned embodiments are described in the above-mentioned order, those skilled in the art can understand that, in order to achieve the effect of the present embodiment, the different steps do not have to be executed in such an order, and they can be executed simultaneously (in parallel) or in a reversed order, for example, steps S1 and S2 can be executed in the order of S2 first and then S1 or simultaneously, and these simple changes are within the protection scope of the present application.

[0066] The technical scheme of the present application has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical schemes after the changes or replacements will all fall within the protection scope of the present application.
