[0008] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the present disclosure, only one type of sensor IC constituting the vibration sensor could be mounted in a washing machine equipped with a vibration sensor. However, when only one type of sensor IC can be mounted, there was a problem that if the supply of the sensor IC decreased, it could affect the production of washing machines.
[0009] Furthermore, since the circuit configuration and sensing characteristics of the vibration sensor vary depending on the type of sensor IC, when installing one of multiple types, it is necessary to store a program corresponding to each sensor IC in the storage unit. In this case, the amount of data to be stored in the storage unit increases, which increases the storage capacity required by the storage unit, resulting in a problem that it is not easy to install one of multiple types of sensor ICs.
[0010] The inventors have come up with the subject matter of the present disclosure in order to solve these problems.
[0011] Therefore, the present disclosure provides a washing machine in which one of a plurality of types of acceleration sensors can be selected and implemented.
[0012] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.
[0013] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.
[0014] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to Fig. 1 to Fig. 7. In the first embodiment, a washing machine 100 will be described as an example of a clothes processing device.
[0015] [1-1. Configuration] [1-1-1. Basic configuration of washing machine] As shown in FIG. 1, a washing machine 100 in this embodiment is configured as a drum type washing machine.
[0016] Washing machine 100 includes a housing 101, a motor 102, a water tub unit 110 provided within housing 101, an acceleration detection unit 120, and a control device 130. Water tub unit 110 includes at least a receiving tub 111 and a washing / spinning tub 112.
[0017] Receiver tube 111 is formed in a cylindrical shape with a bottom, and is configured to be able to store water inside. A water supply path (not shown) for supplying tap water and a drainage path (not shown) for draining water inside receiver tube 111 are connected to receiver tube 111. A water supply valve (not shown) is provided at the top of housing 101, and when the water supply valve is opened, water is supplied into receiver tube 111 via the water supply path. In addition, a drainage valve (not shown) is provided at the bottom of housing 101, and when the drainage valve is opened, water inside receiver tube 111 is drained via the drainage path.
[0018] Washing / spin-drying tub 112 is rotatably disposed inside receiving tub 111. The inner wall surface of washing / spin-drying tub 112 is provided with several protruding plates 112a for agitating the clothes and water holes 112b for communicating water between the inside and outside. Water holes 112b connect receiving tub 111 and washing / spin-drying tub 112, allowing water to flow in and out between receiving tub 111 and washing / spin-drying tub 112.
[0019] A rotating shaft 113 connected to washing / spin-drying tub 112 is provided on the outer bottom of the rear surface of washing / spin-drying tub 112. When rotating shaft 113 rotates, washing / spin-drying tub 112 rotates.
[0020] A bearing case 114 having a bearing (not shown) is provided on the outer bottom of the rear surface of the receiving tube 111. The bearings support a rotating shaft 113. The rotating shaft 113 is connected to the motor 102 via a pulley 115 and a belt 116. When the motor 102 is driven to rotate, the rotation is transmitted to the rotating shaft 113 via the belt and the pulley, and the washing / spinning tub 112 rotates. During operation, the motor 102 drives the washing / spinning tub 112 to rotate in the forward and reverse directions.
[0021] Within housing 101, water tub unit 110 is elastically supported by a plurality of suspensions 103. The lower ends of suspensions 103 are connected to the upper parts of receiving tube 111, and the upper ends of suspensions 103 are connected to the upper part of housing 101.
[0022] A plurality of dampers 105 are provided on frame 104, which is the lower part of housing 101. Damper 105 connects water tank unit 110 to frame 104, and suppresses vibration of water tank unit 110.
[0023] Acceleration sensing unit 120 is provided at the upper front part of water tub unit 110. In this embodiment, acceleration sensing unit 120 is located at the upper front part of the outer surface of receiving tube 111. Acceleration sensing unit 120 will be described in detail later.
[0024] Control device 130 is provided at the bottom of housing 101. As shown in Fig. 2, control device 130 includes control unit 131 and storage unit 132. Control unit 131 controls motor 102, a water supply valve, a drain valve, and the like to control the operation of washing machine 100. Control unit 131 also acquires the output of acceleration sensor 121, which will be described later. Storage unit 132 stores various data necessary for operation.
[0025] [1-1-2. Configuration of acceleration detection unit] As shown in FIG. 3, the acceleration detection unit 120 includes an acceleration sensor 121, an acceleration sensor substrate 122, and a case 123.
[0026] Acceleration sensor 121 detects acceleration at the upper front surface of water bath unit 110. Acceleration sensor 121 is mounted on acceleration sensor board 122. Acceleration sensor board 122 is fixed to case 123 with screws or the like. Acceleration sensor board 122 is electrically connected to control device 130 via a connector and lead wires. This allows information related to the acceleration detected by the acceleration sensor to be output to a control unit of control device 130.
[0027] In this embodiment, washing machine 100 can select and implement one of a plurality of types of acceleration sensors 121 and a plurality of types of acceleration sensor boards as acceleration sensor 121. As shown in FIG. 4, washing machine 100 in this embodiment can select and implement at least one of first acceleration sensor 121A and second acceleration sensor 121B, which is a different type from first acceleration sensor 121A, as acceleration sensor 121. Also, washing machine 100 in this embodiment can select and implement one of first acceleration sensor board 122A corresponding to first acceleration sensor 121A and second acceleration sensor board 122B corresponding to second acceleration sensor 121B as acceleration sensor board 122.
[0028] The multiple types of acceleration sensor boards 122 all have interchangeable mounting structures to the case 123, and can be easily replaced.
[0029] [1-2. Operation] [1-2-1. Washing machine operation] Hereinafter, the operation of the washing machine 100 will be described with reference to FIG.
[0030] When the washing machine is turned on by a user (step S1), the control unit 131 executes the sensor determination control (step S2). The sensor determination control will be described later.
[0031] When the sensor determination control ends, the control unit 131 executes the washing process (step S3). In the washing process, after a water supplying operation is executed to supply water into the receiving tub 111, an agitating operation is executed for a predetermined time in which the washing and spin-drying tub 112 rotates forward, stops, reverses, and stops repeatedly. In the agitating operation, the clothes contained in the washing and spin-drying tub 112 are lifted in the direction of rotation by a plurality of protruding plates 112a for agitating the clothes, and are dropped from the lifted height. This causes a beating wash action to be applied to the clothes contained in the washing and spin-drying tub 112. At the end of the washing process, the water in the receiving tub 111 is drained.
[0032] When the washing step is completed, the control unit 131 executes the rinsing step (step S4). In the rinsing step, as in the washing step, a water supplying operation is executed to supply water into the receiving tub 111, and then an agitating operation is executed for a predetermined period of time in which the washing and spin-drying tub 112 rotates forward, stops, reverses, and stops repeatedly. This dilutes the detergent components contained in the clothes and rinses them out. At the end of the rinsing step, the water in the receiving tub 111 is drained.
[0033] When the rinsing step is completed, the control unit 131 executes the spin-drying step (step S5). In the spin-drying step, the washing / spin-drying tub 112 is rotated at high speed for a predetermined period of time, and the laundry is spin-dried by centrifugal force.
[0034] When the spin-drying process is completed, the control unit 131 ends the washing operation and turns off the power of the washing machine 100 (step S6).
[0035] In addition, if the washing machine 100 has a drying function, the drying process may be performed after the spin-drying process is completed. In that case, the washing and drying operation ends after the drying process is completed.
[0036] [1-2-2. Relationship between acceleration sensor and reference amplitude value] During the washing, rinsing and spin-drying processes, when motor 102 rotates and washing / spin-drying tub 112 begins to rotate, as the rotation speed of washing / spin-drying tub 112 increases, an uneven load is generated in washing / spin-drying tub 112 due to clothes sticking to the tub due to centrifugal force and differences in the water absorbency of the clothes, causing the water tub unit 110 to vibrate.
[0037] Acceleration detection unit 120 attached to water tub unit 110 outputs the acceleration detected by acceleration sensor 121 to control unit 131 at regular time intervals. Control unit 131 calculates a displacement based on the rotation speed of washing and spin-drying tub 112 and the acceleration obtained from acceleration sensor 121, and calculates the difference between the maximum displacement and the minimum displacement during one rotation of washing and spin-drying tub 112 as an amplitude.
[0038] Fig. 6 is a graph showing the relationship between the number of rotations of washing / spin-drying tub 112 in the spin-drying process and the amplitude calculated by control unit 131 when first acceleration sensor 121A and second acceleration sensor 121B are implemented as acceleration sensor 121. Fig. 6(a) shows the amplitude in the front-rear direction of washing machine 100, Fig. 6(b) shows the amplitude in the left-right direction of washing machine 100, and Fig. 6(c) shows the amplitude in the up-down direction of washing machine 100.
[0039] 6, the amplitude value becomes particularly large immediately after washing / spin-drying tub 112 starts rotating and reaches the high-speed range of the spin-drying process (for example, when the rotation speed of washing / spin-drying tub 112 is between 100 rpm and 900 rpm). At this time, vibrations and noise are generated due to contact between receiving tube 111 and housing 101 and resonance of components provided in washing machine 100. Therefore, in order to suppress the generation of vibrations and noise, the storage unit 132 stores reference amplitude values that are upper limits of the amplitude in a certain rotation speed range, as shown in Tables 1 and 2 described below.
[0040] Control unit 131 executes a control change step of changing the rotation drive of motor 102 in order to suppress the generation of vibrations and noise when the magnitude of the calculated amplitude exceeds a reference amplitude value during rotation of washing and spin-drying tub 112. Specifically, in the control change step, control unit 131 may control motor 102 so that the rotation speed of washing and spin-drying tub 112 does not increase, or may control motor 102 to stop the rotation of washing and spin-drying tub 112 once and then rotate it again in order to eliminate uneven distribution of laundry in washing and spin-drying tub 112, or may control motor 102 so that the rotation speed of washing and spin-drying tub 112 fluctuates up and down.
[0041] 6, there is a difference in the detected acceleration value between when the first acceleration sensor 121A is implemented and when the second acceleration sensor 121B is implemented as the acceleration sensor 121, and there is also a difference in the amplitude calculated based on the acceleration. Therefore, in this embodiment, as shown in Tables 1 and 2, the storage unit 132 stores reference amplitude values corresponding to each of the first acceleration sensor 121A and the second acceleration sensor 121B so that the control unit 131 can perform more accurate vibration suppression control.
[0042] [Table 1]
[0043] [Table 2]
[0044] Table 1 shows the reference amplitude values corresponding to the first acceleration sensor 121A.Table 2 shows the reference amplitude values corresponding to the second acceleration sensor 121B.
[0045] As shown in Tables 1 and 2, the first reference amplitude value, which is the reference amplitude value corresponding to first acceleration sensor 121A, is different from the second reference amplitude value, which is the reference amplitude value corresponding to second acceleration sensor 121B. As a result, the reference amplitude value corresponding to the rotation speed of washing / spinning tub 112 differs between the case where first acceleration sensor 121A is implemented as acceleration sensor 121 and the case where second acceleration sensor 121B is implemented, so that appropriate vibration suppression control can be performed for the type of acceleration sensor 121 implemented.
[0046] [1-2-3. Sensor Judgment Control] Next, the operation in the sensor determination control in step S2 in FIG. 5 will be described with reference to FIG.
[0047] When the sensor determination control starts (step S21), the control unit 131 supplies power from the control device 130 to the acceleration sensor board 122, and supplies power to the acceleration sensor 121 (step S22). When power is supplied to the acceleration sensor 121 in step S22, the control unit 131 executes a sensor type acquisition step of acquiring the type of sensor implemented as the acceleration sensor 121 (step S23).
[0048] Based on the information on the type of sensor acquired in step S23, control unit 131 executes a sensor type determination step of determining whether the sensor implemented as acceleration sensor 121 is first acceleration sensor 121A or second acceleration sensor 121B (step S24). Note that control unit 131 may execute the setting of each register of acceleration sensor 121, such as the communication mode and measurement mode, in step S24.
[0049] If it is determined in the sensor type determination step of step S24 that the first acceleration sensor 121A is implemented as the acceleration sensor 121 ("sensor A" in step S24), the control unit 131 decides to use the table corresponding to the first acceleration sensor 121A shown in Table 1 as the reference amplitude value (step S25A). In this case, in the spin-drying process of step S5, the control unit 131 compares the magnitude of the calculated amplitude with the reference amplitude value (first reference amplitude value) of the table corresponding to the first acceleration sensor 121A stored in the storage unit 132. If the magnitude of the calculated amplitude is greater than the first reference amplitude value, the control unit 131 executes a control change step.
[0050] On the other hand, if it is determined in the sensor type determination step of step S24 that the second acceleration sensor 121B is implemented as the acceleration sensor 121 ("sensor B" in step S24), the control unit 131 decides to use the table corresponding to the second acceleration sensor 121B shown in Table 2 as the reference amplitude value (step S25B). In this case, in the spin-drying process of step S5, the control unit 131 compares the magnitude of the calculated amplitude with the reference amplitude value of the table corresponding to the second acceleration sensor 121B stored in the storage unit 132. If the magnitude of the calculated amplitude is greater than the second reference amplitude value, the control unit 131 executes a control change step.
[0051] The control unit 131 may execute the control change step in any or all of the washing process, the rinsing process, and the spin-drying process.
[0052] After completing the above operations, the control unit 131 ends the sensor determination control (step S26).
[0053] The control unit 131 may execute the sensor type determination step of step S24 in any or all of the washing process, the rinsing process, and the spin-drying process, instead of the sensor determination control of step S2.
[0054] [1-3. Effects, etc.] As described above, in this embodiment, washing machine 100 includes housing 101, washing / spinning tub 112 (rotating tub) rotatably provided within housing 101, motor 102 for driving and rotating washing / spinning tub 112, acceleration sensor 121 for detecting the acceleration of vibration, control unit 131 for performing operation, and control device 130 having memory unit 132, and acceleration sensor 121 can be implemented by selecting any one of a plurality of types.
[0055] This allows the mounting of one of the multiple types of acceleration sensors 121 (first acceleration sensor 121A, second acceleration sensor 121B) selectively. Therefore, when a supply shortage of acceleration sensors 121 occurs, a different type of acceleration sensor can be mounted.
[0056] As in the present embodiment, acceleration detection unit 120 is capable of selecting and implementing one of a number of types of acceleration sensor 121, including a first acceleration sensor 121A and a second acceleration sensor 121B that is a different type from first acceleration sensor 121A, and control unit 131 is capable of executing a sensor type acquisition step of acquiring the type of acceleration sensor 121, and a control change step of changing the control of motor 102 when an amplitude value based on the acceleration detected by acceleration sensor 121 is greater than a reference amplitude value based on the rotation speed of the washing / spinning tub, and the reference amplitude value may differ between a case in which first acceleration sensor 121A is implemented as acceleration sensor 121 and a case in which second acceleration sensor 121B is implemented as acceleration sensor 121.
[0057] As a result, in the washing machine 100, the reference amplitude value can be set according to the type of the acceleration sensor 121 mounted thereon, so that appropriate vibration suppression control can be executed, and vibrations occurring during operation can be suppressed. and noise can be further suppressed.
[0058] Furthermore, as in the present embodiment, the storage unit 132 may store, as the reference amplitude value, a first reference amplitude value corresponding to the first acceleration sensor 121A and a second reference amplitude value corresponding to the second acceleration sensor 121B.
[0059] As a result, in washing machine 100, whether first acceleration sensor 121A or second acceleration sensor 121B is implemented as acceleration sensor 121, appropriate vibration suppression control can be executed.
[0060] Also, like in this embodiment, the control unit 131 may execute the sensor type acquisition step after power-on.
[0061] As a result, even if the first acceleration sensor 121A is replaced with the second acceleration sensor 121B before power is turned on due to a malfunction of the acceleration sensor 121, appropriate vibration suppression control can be executed corresponding to the replaced acceleration sensor 121.
[0062] Furthermore, as in the present embodiment, washing machine 100 may further include receiving tub 111 provided within housing 101 and accommodating washing / spin-drying tub 112, and acceleration sensor 121 may be provided in acceleration detection unit 120 attached to receiving tub 111.
[0063] This allows accurate detection of vibrations of receiving tub 111 caused by the rotation of washing / spin-drying tub 112, and therefore allows appropriate vibration suppression control to be performed.
[0064] (Embodiment 2) Hereinafter, the second embodiment will be described with reference to Fig. 8. In the second embodiment, the table related to the reference amplitude value stored in the storage unit is different from that in the first embodiment. Therefore, in the description of the second embodiment, the description of the same points as in the first embodiment will be omitted.
[0065] [2-1. Operation] [2-1-1. Relationship between acceleration sensor and reference amplitude value] In the second embodiment, the memory unit 132 stores reference amplitude values (first reference amplitude values) corresponding to the first acceleration sensor 121A shown in Table 1, and correction values for the first reference amplitude values corresponding to the second acceleration sensor 121B shown in Table 3.
[0066] [Table 3]
[0067] As shown in Table 3, the storage unit 132 stores a correction value for the first reference amplitude value for a portion where the reference amplitude value corresponding to the second acceleration sensor 121B differs from the reference amplitude value (first reference amplitude value) corresponding to the first acceleration sensor 121A. In other words, the storage unit 132 stores a correction value for the first reference amplitude value for the second acceleration sensor 121B only for a rotation speed section that needs to be changed from the reference amplitude value for the first acceleration sensor 121A. In this case, the reference amplitude value corresponding to the second acceleration sensor 121B is calculated by multiplying the first reference amplitude value by the correction value.
[0068] On the other hand, as shown in Table 3, storage unit 132 does not store a correction value for the first reference amplitude value for a portion where the reference amplitude value corresponding to second acceleration sensor 121B is equal to the reference amplitude value (first reference amplitude value) corresponding to first acceleration sensor 121A. As a result, the table of reference amplitude values stored in storage unit 132 only needs to include the reference amplitude values for first acceleration sensor 121A, so that the ROM capacity used by the table of reference amplitude values in storage unit 132 can be reduced.
[0069] [2-1-2. Sensor Judgment Control] The operation of the sensor determination control in the second embodiment will be described with reference to Fig. 8. Note that steps S21 to S23 are the same as those in the first embodiment, and therefore the description thereof will be omitted.
[0070] Control unit 131 executes a sensor type determination step of determining whether the sensor implemented as acceleration sensor 121 is first acceleration sensor 121A or second acceleration sensor 121B based on the sensor type information acquired in step S23 (step S124).
[0071] In the case where it is determined in the sensor type determination step of step S124 that the first acceleration sensor 121A is implemented as the acceleration sensor 121 ("Sensor A" in step S124) "), control unit 131 determines to use the table corresponding to first acceleration sensor 121A shown in Table 1 as the reference amplitude value (step S125A). In this case, control unit 131 compares the magnitude of the calculated amplitude in the spin-drying process of step S5 with the reference amplitude value in the table corresponding to first acceleration sensor 121A stored in storage unit 132.
[0072] On the other hand, if it is determined in the sensor type determination step of step S124 that the second acceleration sensor 121B is implemented as the acceleration sensor 121 ("sensor B" in step S124), the control unit 131 decides to use, as the reference amplitude value, the table of first reference amplitude values corresponding to the first acceleration sensor 121A shown in Table 1 and the table of correction values for the first reference amplitude values shown in Table 3 (step S125B). In this case, in the spin-drying process of step S5, the control unit 131 compares the magnitude of the calculated amplitude with the reference amplitude value calculated based on the table of first reference amplitude values and the correction values stored in the storage unit 132.
[0073] After completing the above operations, the control unit 131 ends the sensor determination control (step S26).
[0074] [2-2. Effects] As described above, in this embodiment, memory unit 132 stores, as a reference amplitude value, a first reference amplitude value corresponding to first acceleration sensor 121A, and memory unit 132 further stores a correction value for the first reference amplitude value corresponding to second acceleration sensor 121B. When second acceleration sensor 121B is implemented as acceleration sensor 121, control unit 131 executes a control change step using a value based on the first reference amplitude value and the correction value as the reference amplitude value.
[0075] (Other embodiments) As described above, the first and second embodiments have been described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to these, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the first and second embodiments to create new embodiments.
[0076] Therefore, other embodiments will be exemplified below.
[0077] In the first and second embodiments, the washing machine 100 has been described as an example of a clothing processing device. The clothing processing device is not limited to the washing machine 100 as long as it has a rotating tub. The clothing processing device may be a drum type washer / dryer, a clothes dryer, a top-loading washing machine, or a twin-tub washing machine.
[0078] In the first and second embodiments, as an example of the sensor type obtaining step, a sensor obtaining step of determining the type of the acceleration sensor 121 has been described. The sensor obtaining step may determine the type of the acceleration sensor, or may determine the type of the acceleration sensor board on which the acceleration sensor is mounted.
[0079] In the first and second embodiments, acceleration sensor 121 provided in receiving tube 111 has been described as an example of an acceleration sensor. The location where the acceleration sensor is provided is not limited to receiving tube 111, as it is only necessary for the acceleration sensor to detect the acceleration of vibration. The acceleration sensor may be mounted on a control board on which electrical components are mounted in the control device. This makes it possible to perform vibration detection without providing a board for mounting the acceleration sensor in addition to the control board. Furthermore, the control device provided with the acceleration sensor may be further provided in the lower part of the housing. This makes it possible to detect the acceleration of vibration without providing a board for mounting the acceleration sensor in addition to the control board. Since the amplitude at the time of the acceleration sensor can be obtained, the vibration that the housing gives to the floor surface can be suppressed. In addition, even when the acceleration sensor is provided on the control board, a control similar to the sensor determination control when the acceleration sensor is provided on the receiving tube may be executed. Note that the acceleration sensor may be provided on both the receiving tube and the control board, and in this case, the acceleration sensor provided on the receiving tube and the acceleration sensor provided on the control board may each have a different table of reference amplitude values. In addition, a plurality of acceleration sensors may be provided, and the control change step may be executed based on the detection results of the plurality of acceleration sensors.
