Description of embodiments

[0010] A channel control device according to one embodiment is described in detail below with reference to the drawings. Design.

[0011] Fig. Figure 1 is a diagram describing an overview of a duct control device 1 according to one embodiment. The duct control device 1 is a device that controls a motor which controls the opening and closing of a duct opening and closing device provided in a duct for directing air from an air conditioning system 2 into a room. Fig. The air conditioning unit 2 is also shown in Figure 1. The duct control device 1 is connected to the air conditioning unit 2.

[0012] Fig. Figure 1 also shows a first channel opening and closing unit 3A, a second channel opening and closing unit 3B, and a third channel opening and closing unit 3C. The first channel opening and closing unit 3A is provided in a first channel. The second channel opening and closing unit 3B is provided in a second channel. The third channel opening and closing unit 3C is provided in a third channel. The first channel, the second channel, and the third channel are in Fig. 1 not shown.

[0013] A first channel opening and closing device 4A is installed in the first channel opening and closing unit 3A. Furthermore, a first motor 5A is attached to the first channel opening and closing unit 3A. Fig. Figure 1 also shows the first duct opening and closing device 4A and the first motor 5A. The first duct opening and closing device 4A is opened and closed by operating the first motor 5A. The first motor 5A controls the opening and closing of the first duct opening and closing device 4A and thus controls an airflow that is directed from the air conditioner 2 into the room via the first duct.

[0014] A second channel opening and closing device 4B is installed in the second channel opening and closing unit 3B. Furthermore, a second motor 5B is attached to the second channel opening and closing unit 3B. Fig. Figure 1 also shows the second duct opening and closing device 4B and the second motor 5B. The second duct opening and closing device 4B is opened and closed by operating the second motor 5B. The second motor 5B controls the opening and closing of the second duct opening and closing device 4B and thus controls an airflow that is directed from the air conditioner 2 into the room via the second duct.

[0015] A third channel opening and closing device 4C is installed in the third channel opening and closing unit 3C. Furthermore, a third motor 5C is attached to the third channel opening and closing unit 3C. Fig. Figure 1 also shows the third duct opening and closing device 4C and the third motor 5C. The third duct opening and closing device 4C is opened and closed by operating the third motor 5C. The third motor 5C controls the opening and closing of the third duct opening and closing device 4C and thus controls an airflow that is directed from the air conditioner 2 into the room via the third duct.

[0016] For each of the first duct opening and closing device 4A, the second duct opening and closing device 4B, and the third duct opening and closing device 4C, "opening" in the phrase "opening and closing" refers to causing air to flow through the duct, and "closing" in the phrase "opening and closing" refers to closing the duct so that no air is caused to flow through the duct. In some cases, each of the first duct opening and closing device 4A, the second duct opening and closing device 4B, and the third duct opening and closing device 4C is controlled such that each of the first duct opening and closing device 4A, the second duct opening and closing device 4B, and the third duct opening and closing device 4C is in a state between a fully closed state and a fully open state.This means that the opening degree of each of the first duct opening and closing device 4A, the second duct opening and closing device 4B, and the third duct opening and closing device 4C can be adjusted. For example, the opening degree of each of the first duct opening and closing device 4A, the second duct opening and closing device 4B, and the third duct opening and closing device 4C can be set to 10% or 50%. The amount of air flowing through the duct is adjusted by changing the opening degree.

[0017] The channel control device 1 is also connected to an operating unit 6 which can be operated by a user. Fig. Figure 1 also shows the control unit 6. The channel control device 1 receives an instruction from the control unit 6, corresponding to an operation performed by the user on the control unit 6, and controls the first motor 5A, the second motor 5B, and the third motor 5C according to the received instruction based on mains voltage current supplied by a mains voltage power supply unit 7. That is, the channel control device 1 controls the first motor 5A, the second motor 5B, and the third motor 5C depending on the operation by the user. Consequently, the channel control device 1 controls the opening and closing of each of the first channel opening and closing device 4A, the second channel opening and closing device 4B, and the third channel opening and closing device 4C, and sets the respective opening degrees. Fig. Figure 1 also shows the mains voltage power supply unit 7. The voltage of the mains voltage power supply is set, for example, to any value between 200 V and 240 V.

[0018] As described above, the duct control device 1 controls the first motor 5A, the second motor 5B, and the third motor 5C according to the user's operation, so that the duct control device 1 controls the opening and closing of each of the first duct opening and closing devices 4A, 4B, and 4C, and sets their respective opening degrees. That is, the user can adjust the amount of air flowing through each duct by controlling the opening and closing of each of the first duct opening and closing devices 4A, 4B, and 4C, and setting their respective opening degrees.

[0019] It should be noted that the channel control device 1 does not need to be connected to the control unit 6 via a cable. The channel control device 1 can be connected to the control unit 6 wirelessly. In short, the channel control device 1 only needs to be able to receive a command from the control unit 6.

[0020] Fig. Figure 2 is a diagram showing the setup of a first channel control device 1A according to the embodiment. The first channel control device 1A is an example of channel control device 1. The first channel control device 1A comprises a power supply board 11 and a motor board 12. The power supply board 11 receives mains voltage current provided by the mains voltage power supply unit 7. The motor board 12 controls a motor based on the mains voltage current received by the power supply board 11. The motor is representative of the first motor 5A, the second motor 5B, and the third motor 5C. The motor is in Fig. 1 not shown. The motor board 12 controls the opening and closing of a duct opening and closing device and the adjustment of the opening degree of the duct opening and closing device. The duct opening and closing device is representative of the first duct opening and closing device 4A, the second duct opening and closing device 4B, and the third duct opening and closing device 4C. The duct opening and closing device is in Fig. 1 not shown.

[0021] The first channel control device 1A further comprises a control board 13, which controls the motor board 12 based on the mains voltage current received from the power supply board 11. The power supply board 11, the motor board 12, and the control board 13 are housed in a single unit 14. The unit 14 is, for example, an enclosure. If the unit 14 is an enclosure, the power supply board 11, the motor board 12, and the control board 13 are arranged within the unit 14. The unit 14 can also be a circuit board. If the unit 14 is a circuit board, the power supply board 11, the motor board 12, and the control board 13 are attached to the unit 14.

[0022] The power supply board 11 has the task of reducing the voltage of the mains voltage. Specifically, the power supply board 11 includes a transformer 111, which reduces the voltage of the mains voltage. For example, the transformer 111 reduces the voltage of the mains voltage to one-tenth of the mains voltage. The area of ​​the transformer 111 is smaller than the area of ​​the power supply board 11. The transformer 111 is located on the power supply board 11. The transformer 111 of the first channel control device 1A is a reinforced insulation transformer, which is a transformer with a relatively low degree of insulation. The motor board 12 controls the motor based on the voltage of the mains voltage or a voltage obtained from the power supply board 11 by reducing the voltage of the mains voltage.

[0023] The first channel control device 1A further comprises a first connection section 15, which connects the power supply board 11 and the motor board 12 and supplies the mains voltage current from the power supply board 11 to the motor board 12. The first channel control device 1A further comprises a second connection section 16, which connects the power supply board 11 and the motor board 12 and supplies low-voltage current from the power supply board 11 to the motor board 12. The low-voltage current is current obtained from the power supply board 11 by reducing the voltage of the mains voltage current. The motor board 12 controls the motor based on either the mains voltage current or the low-voltage current. The mains voltage current is supplied from the power supply board 11 via the first connection section 15.The low-voltage current is supplied from the power supply board 11 via the second connection section 16. It should be noted that the first channel control device 1A does not need to have the second connection section 16 if the first channel control device 1A controls the motor based on the mains voltage current. Fig. Figure 2 shows a state in which the second connection section 16 does not connect the power supply board 11 and the motor board 12.

[0024] The power supply board 11 further includes a diode bridge 112, which converts an alternating voltage received from the transformer 111 into a direct voltage. The power supply board 11 smooths the direct voltage received from the diode bridge 112 and provides the smoothed direct voltage to the control board 13. For example, the power supply board 11 provides the control board 13 with a direct voltage of 30 V. Fig. Figure 2 also shows a mains voltage power supply destination 113 of the power supply board 11. The term "mains voltage power supply destination" refers to a section of the power supply board 11 to which the mains voltage power supply is delivered.

[0025] The control board 13 comprises a converter 131, a board control unit 132, and a communication unit 133. The converter 131 converts the voltage value of a DC voltage. The board control unit 132 controls the motor board 12. The communication unit 133 communicates with the operating unit 6. The current received from the converter 131 is supplied to the board control unit 132 and the communication unit 133. Both the board control unit 132 and the communication unit 133 operate based on the current supplied by the converter 131.

[0026] The motor is connected to the motor board 12. As described above, the motor is representative of the first motor 5A, the second motor 5B, and the third motor 5C. The motor controls the opening and closing of the associated channel opening and closing device and sets the degree of opening. The motor board 12 includes several switches 121 that operate based on the current supplied by the power supply board 11. Each of the several switches 121 is, for example, a C-contact relay. The opening and closing of the channel opening and closing device and the setting of the degree of opening are controlled by the opening and closing of the several switches 121.

[0027] The motor board 12 further includes an on / off control unit 122 for controlling the opening and closing of the duct opening and closing device and for adjusting the degree of opening. The on / off control unit 122 controls the actuation of the multiple switches 121. As described above, the opening and closing of the duct opening and closing device and the adjustment of the degree of opening are controlled by opening and closing the multiple switches 121. The on / off control unit 122 is controlled by the circuit board control unit 132 of the control board 13. That is, the actuation of the multiple switches 121 is controlled by the circuit board control unit 132 of the control board 13. The on / off control unit 122 adjusts the degree of opening of the duct opening and closing device according to the time in which a signal for adjusting the degree of opening of the duct opening and closing device is provided.

[0028] The first channel control device 1A further comprises a basic insulation section 17, which isolates the multiple switches 121 from the on / off control unit 122. The first channel control device 1A controls the channel opening and closing device based on a relatively high voltage. In particular, the first channel control device 1A controls the channel opening and closing device based on the mains voltage current. Therefore, the basic insulation section 17 isolates the multiple switches 121 from the on / off control unit 122. The control side and the high-voltage side are isolated from each other by the basic insulation section 17.

[0029] Fig. Figure 3 is a diagram showing the construction of a second channel control device 1B according to the embodiment. The second channel control device 1B is another example of the channel control device 1. The second channel control device 1B is a device that controls the channel opening and closing device based on a relatively low voltage. The second channel control device 1B includes several components of the first channel control device 1A, with the exception of the first connecting section 15 and the basic insulation section 17. The second channel control device 1B includes a reinforcement insulation section 18. The main difference between the second channel control device 1B and the first channel control device 1A is described below. It is noted that the second channel control device 1B may include the first connecting section 15.

[0030] The motor board 12 is supplied with power obtained by transformer 111 by reducing the voltage of the mains voltage. For example, a voltage of 24 V is supplied to the motor board 12 from the power supply board 11 via the second connection section 16. The transformer 111 of the second channel control device 1B is a reinforced insulation transformer, which is a transformer with a relatively high degree of insulation. The transformer 111 with a relatively high degree of insulation is a transformer that can be replaced by a transformer 111 with a relatively low degree of insulation. Therefore, it is relatively easy to convert the second channel control device 1B into the first channel control device 1A. Similarly, the transformer 111 with a relatively low degree of insulation is a transformer that can be replaced by a transformer 111 with a relatively high degree of insulation.Therefore, it is relatively easy to convert the first channel control device 1A into the second channel control device 1B.

[0031] The power supply board 11 smooths the DC voltage received from the diode bridge 112 and provides the smoothed DC voltage to the control board 13. For example, the power supply board 11 provides the control board 13 with a DC voltage of 24 V. The reinforcing insulation section 18 isolates the multiple switches 121 from the mains voltage power supply destination 113 on the power supply board 11.

[0032] As in the Fig. 2 and Fig. Figure 3 shows that the isolation distance between the multiple switches 121 and the mains voltage power supply destination 113 on the power supply board 11, wherein the mains voltage current is supplied to the mains voltage power supply destination 113 when the motor board 12 controls the motor based on a voltage lower than the voltage of the mains voltage current, is shorter than the isolation distance between the multiple switches 121 and the mains voltage power supply destination 113 on the power supply board 11, wherein the mains voltage current is supplied to the mains voltage power supply destination 113 when the motor board 12 controls the motor based on the voltage of the mains voltage current.

[0033] Fig. Figure 4 is a diagram showing the setup of a third channel control device 1C according to the embodiment. The third channel control device 1C is another example of the channel control device 1. The third channel control device 1C is a device that controls the channel opening and closing device based on a relatively high voltage. In particular, the third channel control device 1C comprises the multiple components of the first channel control device 1A, with the exception of the multiple switches 121. Instead of the multiple switches 121, the third channel control device 1C comprises multiple semiconductor switches 123. Each of the multiple semiconductor switches 123 is a switch for driving the motor. The following mainly describes a difference between the third channel control device 1C and the first channel control device 1A.

[0034] The third channel control device 1C is used, for example, when the number of opening and closing operations of the channel opening and closing device is relatively high, or when the opening degree of the channel opening and closing device needs to be set with relatively high accuracy. Therefore, the motor board 12 includes the multiple semiconductor switches 123, which can be opened and closed in a relatively short time.

[0035] Fig. Figure 5 is a diagram showing the setup of a fourth channel control device 1D according to the embodiment. The fourth channel control device 1D is another example of the channel control device 1. The fourth channel control device 1D is a device that controls the channel opening and closing device based on a relatively low voltage. The fourth channel control device 1D comprises several components of the second channel control device 1B, with the exception of the multiple switches 121. As with the third channel control device 1C, the fourth channel control device 1D comprises multiple semiconductor switches 123 instead of the multiple switches 121. The following mainly describes a difference between the fourth channel control device 1D and the second channel control device 1B.

[0036] The fourth channel control device 1D is used, for example, when the number of opening and closing operations of the channel opening and closing device is relatively high, or when the opening degree of the channel opening and closing device needs to be set with relatively high accuracy. Therefore, the motor board 12 includes the multiple semiconductor switches 123, which can be opened and closed in a relatively short time.

[0037] Fig. Figure 6 is a diagram describing a method in which the channel control device 1, according to the embodiment, adjusts the degree of opening of the channel opening and closing device. A method in which the third channel control device 1C of Fig. 4 and the fourth channel control device 1D of Fig. 5. Adjust the opening degree of the channel opening and closing device, with reference to Fig. 6 described. A current waveform 61 is the waveform of the mains voltage current or the current obtained by reducing the mains voltage current to 24 V. A waveform to be output by the circuit board control unit 132 of the control board 13 is a primary input waveform 63, which is to be input into the on / off control unit 122 of the motor board 12. A motor waveform 62 is the waveform of the current to be supplied to the motor.

[0038] The on / off control unit 122 switches an AC waveform to an on state 64 for a period of time during which the channel opening and closing device is opened according to the opening degree of the channel opening and closing device. The frequency of the mains voltage current is, for example, 50 Hz or 60 Hz. Therefore, the number of motor pulses can be controlled if the switching between on and off can occur on the order of, for example, milliseconds. The reference numeral 65 denotes a zero crossing point of the motor waveform 62. It is possible to control the switching on and off of the semiconductor switching device for any number of pulses of the mains voltage current's sine wave by using a type of semiconductor switching device that performs the on / off switching by detecting the zero crossing point 65. As a result, the channel control device 1 can adjust the opening degree with higher accuracy.

[0039] Fig. Figure 7 is a flowchart that illustrates an example of an operational sequence to be carried out by the channel control device 1 according to the embodiment when the channel control device 1 controls the channel opening and closing device. Fig. Figure 7, for example, shows a control method implemented in a case where the current capacity of transformer 111 on power supply board 11 is relatively small. There are instances where multiple motors cannot be driven simultaneously. If, in such cases, the channel opening and closing devices are opened and closed sequentially, the user may experience stress while waiting for all the devices to open and close. Therefore, opening and closing control is an effective means of avoiding such stress.

[0040] For example, if there are eight duct opening and closing devices and it takes one minute to open and close each device, it will take eight minutes to complete the process of opening and closing all of them. The sequence of Fig. 7 effectively prevents the user from experiencing stress during this time. First, the user performs a channel opening and closing operation using the control unit 6. The channel control device 1 determines whether an open / close state specified in an instruction corresponding to the user's input differs from a current open / close state (S1). That is, in step S1, the channel control device 1 determines whether the state corresponding to the instruction differs from the current open / close state. If it is determined that the state corresponding to the instruction does not differ from the current open / close state (NO in S1), the channel control device 1 terminates the operation.

[0041] If it is determined that the condition corresponding to the instruction differs from the current open / close state (YES in S1), the duct control device 1 activates a motor to open a closed duct opener / closer (S2). As a result, the user may feel a breeze. Even if the airflow does not meet the user's expectations in some cases, the duct control device 1 can alleviate user dissatisfaction. If a stop direction in the motor control is set to a state in which the duct opener / closer is closed, the process of opening the closed duct opener / closer can be carried out within a relatively short time. In this way, it is possible to achieve a relatively short motor operating time.

[0042] The duct control device 1 then activates a motor to close an open duct opening and closing device (S3). Accordingly, the changes to the open / close states of the duct opening and closing devices are completed. The duct control device 1 then sets the opening degrees of the duct opening and closing devices to the levels set by the user (S4).

[0043] As described above, if it is not possible to actuate several channel opening and closing devices simultaneously, the motor board 12 performs a control operation to actuate only one closed channel opening and closing device among the multiple channel opening and closing devices, specifically for a motor that corresponds to the closed channel opening and closing device among the multiple motors. Subsequently, the motor board 12 performs a control operation to actuate an open channel opening and closing device, specifically for a motor that corresponds to the open channel opening and closing device among the multiple motors.

[0044] As described above, the motors are connected to the motor board 12, and the motor board 12 controls the motors. The motor controls the opening and closing of the corresponding duct opening and closing device and sets the degree of opening. Therefore, according to the embodiment, the duct control device 1 can perform control for setting the degrees of opening of the duct opening and closing devices.

[0045] The motor board 12 can perform control for multiple motors to cause multiple channel opening and closing devices to operate sequentially, with the multiple channel opening and closing devices opening and closing multiple channels according to the power of the mains voltage current or the power of the current obtained by reducing the voltage of the mains voltage current.

[0046] The transformer 111 encompassed by the power supply board 11 can be a transformer suitable for a current with a power rating lower than a specified power. If it is not possible to actuate the multiple channel opening and closing devices simultaneously, with the multiple channel opening and closing devices opening and closing multiple channels, the motor board 12 performs a control operation to close one open channel opening and closing device from among the multiple channel opening and closing devices before making adjustments such that the opening degrees of all the multiple channel opening and closing devices correspond to the respective specified opening degrees, with the control operation being performed for one motor which, among the multiple motors, corresponds to the open channel opening and closing device.

[0047] Fig. Figure 8 is a diagram showing a processor 91 that implements part or all of the on / off control unit 122, which is encompassed by the motor board 12 of the first channel control device 1A according to the embodiment. That is, some or all of the functionalities of the on / off control unit 122 can be implemented by the processor 91, which executes programs stored in a memory 92.

[0048] The Processor 91 is a central processing unit (CPU), a processing device, a computing device, a microprocessor, or a digital signal processor (DSP). In Fig. Memory 92 is also shown in 8.

[0049] In a case where some or all functionalities of the on / off control unit 122 are implemented by the processor 91, at least some functionalities of the on / off control unit 122 are implemented by the processor 91 and software, firmware, or a combination of software and firmware. The software or firmware is described as a program and stored in memory 92. The processor 91 implements some or all functionalities of the on / off control unit 122 by reading and executing the programs stored in memory 92.

[0050] In a case where some or all of the functionalities of the on / off control unit 122 are implemented by the processor 91, the first channel control device 1A includes the memory 92 for storing programs that cause the processor 91 to execute some or all of the steps to be performed by the on / off control unit 122.
