Detailed Description
[ First embodiment ]
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the first embodiment, a case where the vibration detection apparatus of the present invention is applied to a waterproof base for a washing machine will be described as an example. Fig. 1 is a perspective view showing a usage mode of a vibration detection apparatus 10 according to a first embodiment. Fig. 2 is a block diagram showing a schematic configuration of the vibration detection apparatus 10.
As shown in fig. 1, the vibration detection apparatus 10 is an apparatus used by placing a washing machine 20 thereon, and has a function as a normal waterproof base. That is, when water leakage from the washing machine 20 occurs, the water leakage to the ground is prevented by catching the water leakage. In addition, the vibration detecting device 10 has a function of detecting vibration of the washing machine 20 and transmitting a signal including the detection information to the outside. The type of the washing machine 20 is not particularly limited, and may be any washing machine such as a vertical washing machine and a drum washing machine.
The vibration detection apparatus 10 includes a waterproof base (apparatus main body) 101 for mounting the washing machine 20 thereon, and a power supply unit 102. The power supply unit 102 has a plug for use by being plugged into a socket of a commercial power supply provided in a house. The waterproof base 101 is connected to the power supply unit 102 via a cable 103, and can perform wired communication and power supply using the cable 103.
As shown in fig. 2, the vibration detection apparatus 10 includes at least one (preferably a plurality of) vibration sensors 104, a first communication unit 105 that transmits the vibration detection result to the outside, and a control unit 106 that controls the vibration detection apparatus 10. The vibration sensor 104 is disposed on the waterproof base 101. The first communication unit 105 and the control unit 106 are preferably disposed in the power supply unit 102.
The vibration detection apparatus 10 shown in fig. 1 is a configuration example in which the waterproof base 101 is formed separately from the power supply 102, and has the following advantages. For example, as a modification of the vibration detection apparatus 10, the following configuration (configuration in which the power supply section 102 is omitted) is also considered: all functional units such as the vibration sensor 104, the first communication unit 105, and the control unit 106 are disposed on the waterproof base 101, and a power cord is connected to the waterproof base 101 to supply power from a socket. However, in this configuration, when the vibration detection apparatus 10 includes an operation input unit, the operation input unit needs to be provided on the waterproof base 101, and it is difficult for the user to operate the operation input unit. In contrast, if the power supply unit 102 is provided separately from the waterproof base 101, the operation input unit can be disposed in the power supply unit 102, and the operation can be easily performed by the user. In addition, in the case where the waterproof base 101 includes the first communication unit 105 and the control unit 106, a countermeasure against vibration and a countermeasure against water against these components are required, but if the power supply unit 102 includes the first communication unit 105 and the control unit 106, countermeasures against vibration and countermeasures against water against these can be omitted or simplified, and the vibration detection apparatus 10 with low cost and high reliability can be provided.
When vibration occurs in the washing machine 20, the vibration is transmitted to the waterproof base 101 disposed in contact with the washing machine 20, and can be detected by the vibration sensor 104. The detection signal of the vibration sensor 104 is transmitted to the control unit 106 via the cable 103. The control unit 106 can transmit a signal including detection information of the vibration sensor 104 (vibration information of the washing machine 20) to the cloud server 30, the communication terminal (for example, a smart phone) 40 of the user, or the like using the first communication unit 105.
Specifically, the first communication section 105 may communicate with the router 50 through a wireless LAN and be network-connected with the cloud server 30 through the router 50. In the cloud server 30, individual identification information of the vibration detection apparatus 10 is registered in association with information of the communication terminal 40 possessed by the user (user registration in advance). As the individual identification information of the vibration detection apparatus 10, the unique address (MAC address or the like) of the first communication unit 105, the manufacturing number of the vibration detection apparatus 10, or the like can be used. Further, as information of the communication terminal 40 held by the user, a mail address, a user ID of various network services, or the like can be used. Thereby, the first communication unit 105 can communicate with the communication terminal 40 via the router 50 and the cloud server 30.
As the vibration sensor 104, a load cell (weight sensor), an acceleration sensor, or the like can be used, but in the first embodiment, a load cell is used for the vibration sensor 104. The load cell in this case is preferably disposed below and near the foot of the washing machine 20 so as to facilitate the application of the load to the washing machine 20, and is more preferably disposed below the front foot of the washing machine 20 where the vibration energy is easily transmitted. However, the present invention is not limited thereto, and the arrangement position is not particularly limited as long as the load of the washing machine 20 is applied to the vibration sensor 104 using the load cell.
The load cell provided in the waterproof base 101 detects the load of the washing machine 20 mounted on the waterproof base 101. When the washing machine 20 vibrates, the load (output voltage) detected by the load cell also vibrates, and thus the load cell can be used as the vibration sensor 104. Further, the intensity of the vibration of the washing machine 20 can be determined based on the amplitude of the output voltage of the vibration sensor 104.
The control unit 106 determines the intensity of vibration of the washing machine 20 based on the output of the vibration sensor 104, and when the vibration level of the washing machine 20 is equal to or higher than a predetermined threshold value, the control unit regards the vibration as vibration of a dangerous level and notifies the user of the vibration to the communication terminal 40. Further, the washing machine 20 itself may have a communication function, and the vibration detection device 10 that detects vibration of a dangerous level may stop the washing machine 20 (send a stop command) when the same router 50 as the vibration detection device 10 is connected. The function of the vibration detection apparatus 10 to transmit the stop command may be a function selectively set by the user in the vibration detection apparatus 10.
In addition, in the case where the washing machine 20 itself does not have a communication function, it may be configured such that: the vibration detecting device 10, which detects the vibration of the dangerous level, stops the washing machine 20 by other methods. As a configuration in this case, a socket portion 102A (see fig. 1) for inserting a power plug into the power supply portion 102 is provided. The washing machine 20 is used by inserting a power plug into the socket 102A of the power supply 102 without inserting the power plug into the socket of the commercial power supply. That is, the washing machine 20 is not directly supplied with power from a commercial power source, but is supplied with power via the power source portion 102. Further, the power supply unit 102 can switch the power supply from the socket unit 102A to be cut off, and when the vibration detection device 10 detects vibration of a dangerous level, the power supply from the socket unit 102A can be cut off to stop the operation of the washing machine 20.
In the above description, when the vibration of the washing machine 20 is equal to or greater than the predetermined threshold, it is determined that the vibration is a vibration of a dangerous level, but the threshold in this case may be arbitrarily set by the user. That is, the threshold value for judging the vibration of the dangerous level is preset as a default value by the manufacturer, but some users consider that the washing machine 20 is stopped even if the vibration is lower than the reference set by the manufacturer. Therefore, the user can arbitrarily set the threshold value for judging the vibration of the risk level, and convenience for the user is improved. As for the setting of the threshold value by the user, an operation input unit (an operation button or the like) may be provided in the power supply unit 102, and the user may set the threshold value via the operation input unit. The setting may be performed via the communication terminal 40 held by the user.
The vibration detection device 10 may detect vibration levels of a plurality of stages by comparing vibration of the washing machine 20 with a plurality of thresholds, and may notify the communication terminal 40 or notify the cloud server 30 according to each vibration level. For example, when the vibration of the washing machine 20 is less than the first threshold value, it is determined that the washing machine 20 is not vibrating. When the vibration of the washing machine 20 is equal to or greater than the first threshold value and smaller than the second threshold value, the vibration of the small level may be determined, and the cloud server 30 may be notified of the determination result. In addition, vibration detection of a small level may also be applied to human detection in the vicinity of the washing machine 20. That is, the small-level vibration detection is regarded as vibration when a person (user) walks around the washing machine 20 or when the person (user) operates the washing machine 20, and can be used for display, lighting control of the in-box lamp, and speech control of information for the user. When the vibration of the washing machine 20 is equal to or greater than the second threshold value and smaller than the third threshold value, the vibration may be determined to be a vibration of a large level, and the cloud server 30 may be notified of the determination result. In addition, when a large-level vibration is detected, the communication terminal 40 may be notified at the same time to prompt the user to change the operation program and the operation condition (the rotation speed of the washing tub, etc.) in the washing machine 20 (for example, the vibration may be reduced by changing the operation program from the standard program to the felt program, etc.). When the vibration of the washing machine 20 is equal to or greater than the third threshold value, the vibration of the risk level is determined, and the determination result is notified to the communication terminal 40.
In addition to detecting the vibration level, the vibration detection device 10 may also notify the communication terminal 40 and notify the cloud server 30 according to the vibration cycle. For example, even when the vibration of the washing machine 20 is detected to be equal to or greater than a predetermined threshold, if the vibration is not detected to be equal to or greater than the predetermined threshold continuously for a predetermined time, the vibration is determined to be the vibration of the small level or the vibration is determined to be absent. When vibration equal to or greater than a predetermined threshold of the washing machine 20 is continuously detected for a predetermined time, it is determined that the vibration is the above-described large-level vibration. Then, when the vibration of the washing machine 20 is a vibration of the third threshold or more for a predetermined time, it is determined that the vibration is a vibration of a dangerous level. This can suppress vibrations that are determined to be of a large level or dangerous level, for example, when a person or object collides with the washing machine 20.
In the above description, the vibration detection device 10 itself determines the vibration level of the washing machine 20, but the present invention is not limited to this, and the cloud server 30 may determine the vibration level. In this case, when the vibration detection device 10 detects the vibration of the washing machine 20, a signal including information of the vibration level is transmitted to the cloud server 30 regardless of the vibration level. The cloud server 30 that received the above signal determines whether the vibration of the washing machine 20 is at a dangerous level, and if so, notifies the communication terminal 40. In addition, when the cloud server 30 determines the risk level, the user can arbitrarily set a threshold value for determining the risk level. The user may access the cloud server 30 from the communication terminal 40 to set the cloud server 30.
When the cloud server 30 determines the vibration level, a signal including information of the vibration level of the vibration detected by the vibration detection device 10 is transmitted to the cloud server 30. Further, in the cloud server 30, it is assumed that the above-described signals are transmitted from the plurality of unspecified vibration detection apparatuses 10. Therefore, the cloud server 30 can collect data on vibration of the washing machine from the unspecified plurality of vibration detection devices 10, and can analyze and estimate failure, degradation, and the like of the washing machine from the collected data. For example, from the load information of the vibration sensor 104, vibration data of the washing machines having the same level of capacity can be collected and statistics can be obtained, and information such as confirmation of the installation environment, degradation of the washing machines, etc. can be notified to a user who vibrates significantly more than the washing machines having the same level. Further, the information such as deterioration of the washing machine may be notified based on the time information of the vibration data from the same vibration detection device 10. Thus, the user can be notified in advance that there is a possibility of malfunction, degradation, or the like of the washing machine, and an incentive to take countermeasures before the malfunction can be provided.
The vibration detection apparatus 10 may have a sensor other than the vibration sensor 104, and may be configured to notify information other than the vibration. For example, the waterproof base 101 has a water leakage detection sensor in an appropriate portion, and the water leakage detection sensor detects water leakage from the washing machine 20, and the vibration detection device 10 notifies the communication terminal 40 of the user. In addition, when the water leakage detection sensor detects water leakage from the washing machine 20, the vibration detection device 10 may stop the operation of the washing machine 20.
[ Second embodiment ]
In the vibration detection apparatus 10 according to the first embodiment, the waterproof base 101 and the power supply 102 are connected by the cable 103. That is, electric power is supplied from the power supply unit 102 to the waterproof base 101 via the cable 103, and communication between the waterproof base 101 and the power supply unit 102 is performed by wired communication via the cable 103. However, the present invention is not limited to this, and communication between the waterproof base 101 and the power supply section 102 may be performed by wireless communication.
Fig. 3 is a block diagram showing a schematic configuration of the vibration detection apparatus 11 according to the second embodiment. The vibration detection device 11 has a waterproof base (device body) 111 and a power supply portion 112. The waterproof base 111 is different from the waterproof base 101 in that the waterproof base 111 further has a second communication portion 113 in addition to the vibration sensor 104. The power supply unit 112 is different from the power supply unit 102 in that the power supply unit 112 includes a third communication unit 114 in addition to the first communication unit 105 and the control unit 106.
In the vibration detecting apparatus 11, communication between the waterproof base 111 and the power supply section 112 is performed by wireless communication between the second communication section 113 and the third communication section 114. Since the wireless communication is a short-range wireless communication, it is preferably performed by Bluetoot h (registered trademark) communication or infrared communication. Further, since the first communication unit 105 performs wireless LAN communication with the router 50, the power supply unit 112 functions as a gateway.
Since the waterproof base 111 is not connected to the power supply unit 112 by a cable, the waterproof base 111 cannot receive power from the power supply unit 112. Therefore, the waterproof mount 111 preferably receives power supply from the battery. The battery used may be a primary battery such as a dry battery or a secondary battery. In the case of using the secondary battery, the vibration power generation element is used as the vibration sensor 104, and the vibration power generation element is combined with the secondary battery, whereby the vibration power generation element generates power by the vibration of the washing machine 20, and the generated power can be charged into the secondary battery and used as the operation power of the second communication unit 113. In this case, the secondary battery may be used as a capacitor or the like, and when the vibration power generation element receives vibration of a predetermined threshold value or more for a predetermined time, electric power capable of operating the second communication unit 113 may be stored in the secondary battery. Accordingly, when no external power is supplied, only the information of the vibration of the large level or the dangerous level in the first embodiment can be communicated to the power supply unit 112.
[ Third embodiment ]
In the first and second embodiments described above, the case where the vibration detection apparatus of the present invention is applied to a waterproof base is exemplified. However, the present invention is not limited thereto, and the present invention may be applied in addition to the waterproof base.
Fig. 4 is a perspective view showing a usage pattern of the vibration detection apparatus 12 according to the third embodiment. The vibration detection device 12 includes a pad (device body) 121 for mounting the washing machine 20 thereon and a power supply 112. The pad 121 has a different appearance from the waterproof base 111, but has the same functional structure as the waterproof base 111 shown in fig. 3. In the pad 121, a pad 122 including the vibration sensor 104 is laid under the foot portion of the washing machine 20 (contact arrangement), and vibration transmitted from the washing machine 20 to the pad 122 is detected. The communication sub-unit 123 including the second communication unit 113 is connected to the pad 122, and the pad 121 can communicate with the power supply unit 112 via the communication sub-unit 123.
In the vibration detecting apparatus 12 shown in fig. 4, two mats 122 are used, but the number of mats 122 is not particularly limited. For example, the number of mats 122 may be 4, and the mats 122 may be laid on all 4 feet of the washing machine 20. Further, in the case where a plurality of mats 122 are used, it is not necessary to include the vibration sensor 104 in all the mats 122. For example, four mats 122 may be laid on all four feet of the washing machine 20, but the vibration sensor 104 is included only in two feet of the front side of the washing machine 20.
Fig. 5 is a perspective view showing a usage pattern of the other vibration detection apparatus 13 according to the third embodiment. The vibration detection device 13 includes a rubber leg (device body) 131 for mounting the washing machine 20 and a power supply 112. The rubber leg 131 has a different appearance from the waterproof base 111, but has the same functional configuration as the waterproof base 111 shown in fig. 3. That is, the rubber foot 131 includes the vibration sensor 104 and the second communication portion 113. By placing the rubber foot 131 under the foot of the washing machine 20 (contact configuration), vibration transmitted from the washing machine 20 to the rubber foot 131 is detected. Further, the rubber foot 131 can communicate with the power supply unit 112 via the second communication unit 113.
In the vibration detection device 13 shown in fig. 5, two rubber feet 131 are used, but the number of rubber feet 131 is not particularly limited. For example, the number of rubber feet 131 may be 4, and the rubber feet 131 may be placed on all of the 4 feet of the washing machine 20. In addition, the washing machine 20 may use the rubber foot 131 including the vibration sensor 104 and the second communication unit 113 in combination with a general rubber foot including no sensor or communication unit. For example, rubber feet 131 may be used for both feet on the front side of the washing machine 20, and general rubber feet may be used for both feet on the rear side.
Fig. 6 is a perspective view showing a usage pattern of the other vibration detection apparatus 14 according to the third embodiment. The vibration detection device 14 includes a detection portion (device main body) 141 and a power supply portion 112 that are attached (contact-disposed) to a side surface of the casing of the washing machine 20 by a magnet or the like. The appearance of the detection unit 141 is different from that of the waterproof base 111, but the functional configuration is the same as that of the waterproof base 111 shown in fig. 3. That is, the detection section 141 includes the vibration sensor 104 and the second communication section 113. However, since the detection unit 141 is different from the waterproof base 111 and the washing machine 20 is not mounted thereon, it is preferable to use an acceleration sensor as the vibration sensor 104 instead of the load cell. The detection unit 141 is also capable of communicating with the power supply unit 112 via the second communication unit 113.
In the vibration detection device 14 shown in fig. 6, one detection unit 141 is used, but the number of detection units 141 is not particularly limited. In the detection section 141, since the acceleration sensor serving as the vibration sensor 104 can detect the vibration amount in the predetermined direction, two detection sections 141 may be used to detect vibrations in different two directions.
For example, in the case where the washing machine 20 is a vertical washing machine, the vibration of the vertical washing machine is mainly vibration in the left-right direction and the front-rear direction. In this case, the detection units 141 may be attached to the rear surface and the side surfaces of the washing machine 20, respectively, and the front-rear direction vibration may be detected by the rear-surface-side detection unit 141, and the left-right direction vibration may be detected by the side-surface-side detection unit 141. In the case where the washing machine 20 is a drum-type washing machine, the vibration in the drum-type washing machine is mainly vibration in the left-right direction and the up-down direction. In this case, the detection units 141 may be attached to the side surfaces and the upper surface of the washing machine 20, respectively, and the lateral-side detection unit 141 may detect the lateral-direction vibration, and the upper-surface-side detection unit 141 may detect the vertical-direction vibration.
As described above, if vibration information of different two directions is detected by the vibration detecting device 14 and information related to the vibration is collected to the cloud server 30, the utility value thereof is higher if the collected information is used for development of the washing machine.
In addition, in the vibration detection deviceIn the above, the pad 121, the rubber leg 131, and the detection unit 141 are all configured to communicate with the power supply unit 112 by wireless communication. However, the present invention is not limited thereto, and wired communication using a cable may be performed. That is, the functional configuration of the vibration detection apparatuses 12 to 14 may be the same as that of the vibration detection apparatus 10 shown in fig. 2.
[ Fourth embodiment ]
In the first embodiment, when the vibration detection device 10 detects vibration of a dangerous level during operation of the washing machine 20, it is described that the vibration can be reported to the user. However, there are other applications for vibration detection in the present invention. In the fourth embodiment, another application example of the vibration detection apparatus 10 will be described. Of course, such an application example can also be applied to the vibration detection apparatuses 11 to 14 in the second and third embodiments.
For example, the vibration detecting device 10 can detect and notify the communication terminal 40 when a child or a pet enters the washing machine 20. That is, if the washing machine 20 is not operated but vibration of the washing machine 20 is detected by the vibration detecting device 10, it is conceivable that a child or a pet enters the washing machine 20.
When the entry of a child or pet is detected by the vibration detection device 10 by the above-described method, the vibration detection device 10 needs to recognize the operation condition (whether it is in operation or not) of the washing machine 20. In this regard, the washing machine 20 has a communication function, and if communication is possible between the washing machine 20 and the vibration detection device 10, the vibration detection device 10 can receive the operation condition of the washing machine 20 through the communication.
On the other hand, when the washing machine 20 does not have the communication function, the power plug of the washing machine 20 is inserted into the socket 102A of the power supply 102 and the power is supplied to the washing machine 20 via the power supply 102, whereby the operation state of the washing machine 20 can be determined. In this case, the vibration detection device 10 can determine the operation state of the washing machine 20 by monitoring the amount of electric power supplied to the washing machine 20. That is, the electric power supply amount is increased by the motor drive during the operation of the washing machine 20, and is decreased by the motor stop during the non-operation of the washing machine 20. Accordingly, the amount of electric power supplied to the washing machine 20 can be compared with a predetermined threshold, and when the amount of electric power supplied is equal to or greater than the threshold, it is determined that the washing machine 20 is operating, and when the amount of electric power supplied is less than the threshold, it is determined that the washing machine is not operating.
When the vibration detection device 10 detects the entry of a child or a pet (particularly a child), even when a load cell is used for the vibration sensor 104, the detection can be performed based on the increase amount and the increase rate of the load detected by the vibration sensor 104. That is, when a child enters the washing machine 20, the load detected by the vibration sensor 104 increases more than when laundry is put in, and the load varies greatly in a short time (the rate of increase is high). Further, even when the pet enters the washing machine 20, the load detected by the vibration sensor 104 varies greatly in a short time as compared with the case where the laundry is put in. Therefore, the entry of children or pets can also be detected based on the increase in the load detected by the vibration sensor 104.
The vibration detection device 10 can also be used for detecting an earthquake. When detecting an earthquake, the cloud server 30 registers the individual identification information of the vibration detection apparatus 10 in association with the address of the location of the washing machine 20. In the cloud server 30, when vibration detection information is simultaneously transmitted from many unspecified vibration detection apparatuses 10 in a specific region, the cloud server 30 can detect that an earthquake occurs in the above-described specific region.
All aspects of the embodiments disclosed herein are exemplary and not to be construed in a limiting sense. Therefore, the technical scope of the present invention is not to be interpreted by the above embodiments only, but is to be defined based on the description of the claims. Further, all changes which come within the meaning and range of equivalency of the claims are to be embraced therein.
