Description

Technical Field

[0001] This disclosure relates to a remote control. Background Technology

[0002] As an oxygen concentrator that generates air containing oxygen at a concentration higher than that in the air (hereinafter referred to as high-concentration oxygen) and supplies it to the user, the oxygen concentrator disclosed in Patent Document 1 is known. Patent Document 1 discloses a remote control device for setting the flow rate of high-concentration oxygen supplied from the main body of the oxygen concentrator to the user via remote operation. The remote control device includes a confirmation button, a flow rate setting change button, a display screen, and a sliding cover. The cover prevents accidental operation of the change button when closed.

[0003] When the user sets the flow rate of the high-concentration oxygen, they press the confirmation button on the remote control. When the confirmation button is pressed, the remote control communicates with the oxygen concentrator and displays the current set flow rate value received from the oxygen concentrator on the screen. After confirming the display, the user presses the change button with the hood open to change the flow rate of the high-concentration oxygen. This change signal is sent to the oxygen concentrator. The oxygen concentrator adjusts the flow rate of the high-concentration oxygen based on the received signal.

[0006] [Patent Document 1] International Publication No. 2011 / 087111 Summary of the Invention

[0007] In the remote control device disclosed in Patent Document 1, the confirmation button is exposed even when the cover is closed, so users may sometimes accidentally operate the confirmation button. Even if the confirmation button is accidentally operated, the remote control device will start communicating with the main body of the oxygen concentrator, thus consuming excess power through this communication and shortening the battery life of the remote control device.

[0008] The purpose of this disclosure is to reduce the power consumption of remote controls.

[0009] (1) The remote control disclosed herein is a remote control for remotely operating the main body of an oxygen concentrator that supplies high-concentration oxygen to a user, comprising: a main body; a display unit disposed on the main body and displaying the operating status of the oxygen concentrator main body; an operation button disposed on the main body; a cover that is movable relative to the main body between a closed position covering the operation button and an open position exposing the operation button; a first detection unit that detects that the cover is in the closed position; a communication unit that is capable of communicating with the oxygen concentrator main body; and a control unit that outputs a command signal to the communication unit to communicate with the oxygen concentrator main body based on the detection result of the first detection unit.

[0010] According to the remote controller disclosed herein, the control unit can, for example, prevent the communication unit from outputting a command signal to the oxygen concentrator body when the first detection unit detects that the cover is in the closed position of the cover operation button. Therefore, when the cover is in the closed position, the communication unit does not communicate with the oxygen concentrator body, thus suppressing the power consumption of the remote controller.

[0011] (2) Based on the remote control in (1) above, preferably, the operation buttons include: a power button for turning the power supply on and off to the main body of the oxygen concentration device; and a change button for changing the flow rate of the high-concentration oxygen supplied to the user.

[0012] In this situation, when the first detection unit detects that the cover is in the closed position covering the power button and the change button, the control unit does not output a command signal to the communication unit to communicate with the main body of the oxygen concentrator. Therefore, when the cover is in the closed position covering the power button and the change button, the communication unit does not communicate with the main body of the oxygen concentrator, thus suppressing the power consumption of the remote control.

[0013] (3) Preferably, the remote control of (1) or (2) further includes a second detection unit, which detects the gripping state of the main body being gripped by the user, and the control unit outputs the command signal based on the detection results of the first detection unit and the detection results of the second detection unit.

[0014] In this scenario, for example, if the first detection unit does not detect the closed position of the cover, the control unit can output a command signal to the communication unit only when the second detection unit detects the gripping state of the main body. Therefore, even if the cover is in the open position, the communication unit will not communicate with the oxygen concentrator main body until the user grips the main body, thus further reducing the power consumption of the remote control.

[0015] (4) Based on the remote control in (3) above, it is preferable that the second detection unit is an acceleration sensor.

[0016] In this situation, the gripping state of the main body can be easily detected by an accelerometer.

[0017] (5) Based on the remote control of (4), it is preferable that the main body is formed to be longer in one direction, and the acceleration sensor is disposed at the end of the main body in the one direction.

[0018] In this situation, when the user grips the main body, the acceleration of the end of the main body in one direction is greater than the acceleration of the middle part of the main body in one direction. Therefore, it is easier to detect the gripping state of the main body.

[0019] (6) Based on the remote control of any one of (1) to (5), it is preferred that the first detection unit has: a magnet disposed on one of the main body and the cover; and a magnetic sensor disposed on the other of the main body and the cover, and detects the magnetic force of the magnet when the cover is in the closed position.

[0020] In this case, the closed position of the cover can be detected using a simple structure formed by a magnet and a magnetic sensor. Attached Figure Description

[0031] [Oxygen Concentration Unit]

[0032] Figure 1 This is a perspective view showing an oxygen concentration apparatus according to an embodiment of the present disclosure. The oxygen concentration apparatus of the present disclosure is a device that supplies a user with high-concentration oxygen, containing oxygen at a concentration higher than that found in air. The oxygen concentration apparatus is used, for example, in home oxygen therapy, where high-concentration oxygen is provided to users such as patients with respiratory diseases.

[0033] Figure 1 The oxygen concentrator 1 shown includes: an oxygen concentrator body 2, which generates high-concentration oxygen and supplies high-concentration oxygen to the user; and a remote control 3, which is used to remotely operate the oxygen concentrator body 2.

[0034] The main body 2 of the oxygen concentration device includes: an air pump for discharging raw material air (pressurized air); an adsorption cylinder for generating high-concentration oxygen from the raw material air; an oxygen container for storing the generated high-concentration oxygen; a flow control unit for controlling the flow rate of high-concentration oxygen; and a communication unit for communicating with a remote controller 3, etc.

[0035] [Remote Control]

[0036] Figure 2 This shows the front view of remote control 3. Figure 2 The left side shows the non-use state of remote control 3. Figure 2 The right side shows the status of remote control 3 when in use. Figure 3 This is a side view of the remote control 3. In the following description, the terms top, bottom, front, back, left, and right refer to... Figure 2 as well as Figure 3 The arrow shown. Specifically, for example, in Figure 2 as well as Figure 3 In the diagram, among the mutually orthogonal arrows X, Y, and Z, the direction indicated by arrow X (the first direction) is taken as the left-right direction, the direction indicated by arrow Y (the second direction) is taken as the up-down direction, and the direction indicated by arrow Z (the third direction) is taken as the front-back direction. However, this is only one example; for instance, the first direction can be replaced with the up-down direction, and the second direction can be replaced with the left-right direction.

[0037] exist Figure 2 as well as Figure 3 In the remote control 3, there are a main body 4, a display 5, operation buttons 6, a cover 7, and a battery 8.

[0038] The main body 4 is formed, for example, in a cuboid shape. In this embodiment, the main body 4 is elongated in the vertical direction (one direction). The shape of the main body 4 is not limited to that of this embodiment. For example, the main body 4 may also be formed in a cuboid shape that is elongated in the horizontal direction.

[0039] The main body 4 includes: a first housing 41 disposed on the front side; a second housing 42 disposed on the rear side; and a substrate 43 covered by the first housing 41 and the second housing 42. The substrate 43 is formed into a generally rectangular shape that is longer in the vertical direction. The length of the substrate 43 in the vertical direction is shorter than the length of the first housing 41 (second housing 42) in the vertical direction. The substrate 43 is disposed biased towards the upper side of the first housing 41 (second housing 42).

[0040] Within the main body 4, a battery 8 serving as a power source is provided at a position lower than the substrate 43. In this embodiment, two batteries 8 are provided within the main body 4. Each power source 8 is, for example, a dry cell battery. The main body 4 has a cover 44 that is detachably provided on the lower side of the second housing 42. Each battery 8 can be replaced by removing the cover 44 from the second housing 42. The type and number of batteries 8 are not limited to this embodiment. For example, the battery 8 may also be a rechargeable battery.

[0041] Figure 4 This is a perspective view of the front surface of substrate 43 from the lower right side. Figure 5 This is a perspective view of the rear surface of substrate 43 from the lower left side. Figure 4 as well as Figure 5 As shown, terminals 45 electrically connected to the electrodes of the battery 8 are mounted on the lower end of the substrate 43. In this embodiment, the substrate 43 has the same number of terminals 45 as the number of batteries 8 (two in this case). A speaker 46 is mounted on the right side of the front surface of the substrate 43. The speaker 46 is a sound transmitter used to notify the user of various information.

[0042] exist Figure 2 as well as Figure 4 In this embodiment, the display unit 5 is disposed on the upper side of the front surface of the substrate 43 of the main body 4. The display unit 5 is, for example, an organic EL display screen. The display unit 5 has a display surface 5a, which displays information obtained by the communication unit 14 (described later) from the oxygen concentrator main body 2 through communication with the oxygen concentrator main body 2. The display unit 5 in this embodiment displays the operating status of the oxygen concentrator main body 2 on the display surface 5a. An opening 41a is formed on the upper side of the first housing 41 to expose the display surface 5a.

[0043] On the display surface 5a of the display unit 5, the operating state is displayed, for example, whether the oxygen concentration device body 2 is in operation or stopped, or the current flow rate of high-concentration oxygen supplied to the user is displayed. The display unit 5 is not limited to this embodiment; for example, it may be a liquid crystal display screen.

[0044] like Figure 4 As shown, a plurality of switching elements 47 are mounted on the front surface of the substrate 43, below the display section 5. Each switching element 47 switches between contacts by pressing the operation button 6. The plurality of switching elements 47 includes a first switching element 47a, a second switching element 47b, a third switching element 47c, and a fourth switching element 47d.

[0045] The first switching element 47a and the second switching element 47b are mounted on the lower side of the front surface of the substrate 43, spaced apart from each other in the left-right direction. The first switching element 47a is used when the power supply to the oxygen concentrator body 2 is turned on. The second switching element 47b is used when the power supply to the oxygen concentrator body 2 is turned off.

[0046] The third switching element 47c and the fourth switching element 47d are mounted on the front surface of the substrate 43, spaced apart from each other in the vertical direction, above the first switching element 47a and the second switching element 47b. The third switching element 47c is used to increase the flow rate of high-concentration oxygen supplied to the user. The fourth switching element 47d is used to decrease the flow rate of high-concentration oxygen supplied to the user.

[0047] The mounting positions of the buttons 61a, 61b, 62a, and 62b on the substrate 43 are not limited to those in this embodiment.

[0048] exist Figure 2 as well as Figure 4 In this embodiment, operation button 6 is located on the front surface of the first housing 41. Operation button 6 is operated by the user pressing it in. Operation button 6 in this embodiment includes: a power button 61 for switching the power supply to the oxygen concentration device body 2 on and off; and a change button 62 for changing the flow rate of high-concentration oxygen supplied to the user. Furthermore, operation button 6 in this embodiment does not include the confirmation button disclosed in Patent Document 1.

[0049] The power button 61 includes an input button 61a and a stop button 61b. The input button 61a is operated when the power to the oxygen concentrator body 2 is turned on. Therefore, the input button 61a is positioned on the front surface of the first housing 41, in front of and close to the first switching element 47a on the substrate 43. When the power to the oxygen concentrator body 2 is turned on, the first switching element 47a is activated when the user presses the input button 61a.

[0050] The stop button 61b is operated when the power to the oxygen concentration unit 2 is turned off. Therefore, the stop button 61b is positioned on the front surface of the first housing 41, in front of and near the second switching element 47b on the substrate 43. When the power to the oxygen concentration unit 2 is turned off, the second switching element 47b is activated when the user presses the stop button 61b.

[0051] The change button 62 includes a plus button 62a and a minus button 62b. The plus button 62a is operated when increasing the flow rate of the high-concentration oxygen supplied to the user. Therefore, the plus button 62a is positioned on the front surface of the first housing 41, in front of and near the third switching element 47c on the substrate 43. When the user presses the plus button 62a to increase the flow rate of the high-concentration oxygen supplied to the user, the third switching element 47c is activated.

[0052] The minus button 62b is operated when reducing the flow rate of high-concentration oxygen supplied to the user. Therefore, the minus button 62b is positioned on the front surface of the first housing 41, in front of and near the fourth switching element 47d on the substrate 43. When the user presses the minus button 62b to reduce the flow rate of high-concentration oxygen supplied to the user, the fourth switching element 47d is activated.

[0053] exist Figure 2 In the middle, a cover 7 is provided on the first housing 41 of the main body 4. The cover 7 is, for example, a flat plate member formed in a generally rectangular shape. The cover 7 is configured to cover the closed position of the operation button 6 relative to the first housing 41. Figure 2 The position shown on the left) and the open position that exposes the operation button ( Figure 2 The cover 7 in this embodiment is movable between the positions shown on the right side. Specifically, the left and right edges of the cover 7 are supported on the front side of the first housing 41 so that they can slide in the vertical direction.

[0054] When closed, cover 7 completely covers the power button 61 (input button 61a, stop button 61b) and the change button 62 (plus button 62a, minus button 62b). When the user is not operating the operation button 6 (when not using the remote control 3), the cover 7 can be slid upwards to the closed position. This prevents the user from accidentally operating the power button 61 and the change button 62.

[0055] When cover 7 is in the open position, the power button 61 (input button 61a, stop button 61b) and the change button 62 (plus button 62a, minus button 62b) are fully exposed. When the user operates the operation button 6 (when using remote control 3), cover 7 is slid downwards to the open position. This allows the user to operate the power button 61 and the change button 62.

[0056] Cover 7 is not limited to this embodiment. For example, cover 7 may also be configured to swing relative to the first housing 41 about an axis extending in the vertical or horizontal direction. In addition, cover 7 may cover at least one of the power button 61 and change button 62 in the closed position and expose at least one of the power button 61 and change button 62 in the open position.

[0057] Figure 6 This is a perspective view of the front surface of substrate 43 from the lower left side. Figure 5 and Figure 6 In this configuration, the remote controller 3 also includes a first detection unit 11, a second detection unit 12, and a communication module 13. The first detection unit 11 is disposed on the front side of the substrate 43. The second detection unit 12 and the communication module 13 are disposed on the rear side of the substrate 43. Alternatively, the second detection unit 12 and the communication module 13 may also be disposed on the front side of the substrate 43.

[0058] [First Testing Department]

[0059] The first detection unit 11 detects whether the cover 7 is in the closed position. In this embodiment, the first detection unit 11 includes a magnet 11a disposed on the cover 7 and a magnetic sensor 11b mounted on the substrate 43.

[0060] In this embodiment, the magnet 11a is a permanent magnet. The magnet 11a is fixed to the upper left end of the rear surface (back side) of the cover 7 and moves together with the cover 7 in the vertical direction.

[0061] The magnetic sensor 11b is mounted on the front surface of the substrate 43 at a position close to and opposite to the magnet 11a when the cover 7 is in the closed position (see also...). Figure 4 When the cover 7 is in the closed position, the magnetic sensor 11b detects the magnetic force of the magnet 11a. When the magnetic sensor 11b detects the magnetic force of the magnet 11a, it outputs a first detection signal to the control unit 15 (described later).

[0062] The first detection unit 11 is not limited to this embodiment. For example, the first detection unit 11 may also be composed of a magnet provided on the substrate 43 and a magnetic sensor provided on the cover 7.

[0063] [Second Inspection Department]

[0064] The second detection unit 12 detects the gripping state of the main body 4 when it is grasped by the user. In this embodiment, the second detection unit 12 is an acceleration sensor. Hereinafter, the second detection unit 12 is also referred to as the acceleration sensor 12. The acceleration sensor 12 detects the acceleration of the main body 4 generated when the user grasps the main body 4. The acceleration sensor 12 is provided at the end of the substrate 43 in the longitudinal direction (one direction), that is, at the part of the substrate 43 where the acceleration increases. In this embodiment, the acceleration sensor 12 is mounted on the right side of the upper end of the rear surface of the substrate 43. When the acceleration sensor 12 detects the user's gripping state of the main body 4, it outputs a second detection signal to the control unit 15 (described later).

[0065] The mounting position of the second detection unit 12 is not limited to this embodiment. For example, the second detection unit 12 may be mounted on the left side of the upper end of the substrate 43, or it may be mounted on the lower end of the substrate 43. The second detection unit 12 is not limited to an acceleration sensor. For example, the second detection unit 12 may also be a temperature sensor that detects the user's body temperature, a pressure sensor that detects the user's gripping pressure on the main body 4, or an electrostatic sensor that detects the static electricity carried by the user, etc.

[0066] [Communication Module]

[0067] The communication module 13 is mounted on the substrate 43. In this embodiment, the communication module 13 is mounted on the upper left side of the substrate 43. Figure 7 This is a block diagram showing the internal structure of the communication module 13. (Example) Figure 7 As shown, the communication module 13 includes a communication unit 14 and a control unit 15.

[0068] The communication unit 14 is capable of communicating with the oxygen concentration device body 2. The communication unit 14 can communicate wirelessly with the aforementioned communication unit of the oxygen concentration device body 2, for example, via a short-range wireless communication method (Bluetooth, etc.). The communication unit 14 can also communicate with the oxygen concentration device body 2 via a wired communication method.

[0069] [Control Department]

[0070] The control unit 15 performs communication control for the communication unit 14. The control unit 15 may be a microcomputer, for example, equipped with a processor such as a CPU and a memory such as RAM and ROM. The control unit 15 performs its intended functions by executing programs installed in the memory through the processor. The control unit 15 may also be implemented using LSI, ASIC, FPGA, or other hardware.

[0071] In this embodiment, the control unit 15 outputs a command signal to the communication unit 14 to communicate with the oxygen concentration device main body 2 based on the detection results of the first detection unit 11 (magnetic sensor 11b) and the second detection unit (accelerometer sensor 12). Specifically, the control unit 15 outputs the command signal to the communication unit 14 only when the second detection unit 12 detects that the main body 4 is in a gripping state, and the first detection unit 11 does not detect that the cover 7 is in a closed position.

[0072] Figure 8 This is a flowchart illustrating an example of communication control performed by the control unit 15. Figure 8 First, the control unit 15 determines whether a first output signal has been input to the first detection unit 11 from the closed position of the detection cover 7 (step ST1).

[0073] When the first output signal is input (in the case of "Yes" in step ST1), that is, when the cover 7 is in the closed position, the control unit 15 performs the determination in step ST1 again after a predetermined time. On the other hand, when the first output signal is not input (in the case of "No" in step ST1), that is, when the cover 7 is in a position other than the closed position, the control unit 15 moves to the next step ST2.

[0074] In step ST2, the control unit 15 determines whether a second output signal has been input from the second detection unit 12, which detects the user's gripping state of the main body 4. If no second output signal has been input (in the case of "No" in step ST2), that is, if the main body 4 is not gripped by the user, the control unit 15 returns to step ST1.

[0075] On the other hand, when the control unit 15 receives a second output signal (the case where "yes" is in step ST2), that is, when the main body 4 is being held by the user, it moves to the next step ST3.

[0076] In step ST3, the control unit 15 outputs a command signal to the communication unit 14 to communicate with the oxygen concentration unit 2 (step ST3), and the process ends. The communication unit 14 starts wireless communication with the oxygen concentration unit 2 according to the command signal from the control unit 15.

[0077] The control unit 15 performs the determination of step ST2 after the determination of step ST1, but it can also perform the determination of step ST1 after the determination of step ST2.

[0078] [Variations on communication control]

[0079] Figure 9This is a flowchart illustrating a modified example of the communication control performed by the control unit 15. In this modified example, the control unit 15 outputs a command signal to the communication unit 14 to communicate with the oxygen concentration device body 2 based on the detection result of the first detection unit 11. Specifically, the control unit 15 does not output the command signal to the communication unit 14 to communicate with the oxygen concentration device body 2 when the first detection unit 11 detects that the cover 7 is in the closed position, but outputs the command signal when the first detection unit 11 does not detect that the cover 7 is in the closed position. The specific control will be described below.

[0080] exist Figure 9 First, the control unit 15 determines whether a first output signal has been input to the first detection unit 11 from the closed position of the detection cover 7 (step ST11). If the first output signal has been input (in the case of "yes" in step ST11), that is, if the cover 7 is in the closed position, the control unit 15 performs the determination in step ST11 again after a predetermined time.

[0081] On the other hand, if the control unit 15 is not input with the first output signal (in the case of "No" in step ST11), that is, if the cover 7 is in a position other than the closed position, it moves to the next step ST12.

[0082] In step ST12, the control unit 15 outputs a command signal to the communication unit 14 to communicate with the oxygen concentration unit 2, and then ends the processing. The communication unit 14 then begins wireless communication with the oxygen concentration unit 2 based on the command signal from the control unit 15.

[0083] [Effects of the Implementation Method]

[0084] (1) The remote controller 3 of the above embodiment includes: a main body 4; a display 5, which is disposed on the main body 4 and displays the operating status of the oxygen concentration device main body 2; and an operation button 6 disposed on the main body 4. The remote controller 3 includes a cover 7, which is movable relative to the main body 4 between a closed position covering the operation button 6 and an open position exposing the operation button 6. The remote controller 3 includes: a first detection unit 11, which detects that the cover 7 is in the closed position; a communication unit 14, which is capable of communicating with the oxygen concentration device main body 2; and a control unit 15, which outputs a command signal to the communication unit 14 to communicate with the oxygen concentration device main body 2. Furthermore, in the above modified example, the control unit 15 outputs a command signal to the communication unit 14 to communicate with the oxygen concentration device main body 2 based on the detection result of the first detection unit 11. According to this structure, the control unit 15 can refrain from outputting a command signal to the communication unit 14 to communicate with the oxygen concentration device main body 2 when the first detection unit 11 detects that the cover 7 is in the closed position. Therefore, when the cover 7 is in the closed position, the communication unit 14 does not communicate with the oxygen concentration unit body 2, thus suppressing the power consumption of the remote control 3. As a result, the lifespan of the battery 8 can be increased.

[0085] (2) The operation button 6 in the above embodiment includes: a power button 61 for turning the power on and off of the oxygen concentration device body 2; and a change button 62 for changing the flow rate of high-concentration oxygen supplied to the user. According to this structure, the control unit 15 in the above modified example can stop outputting command signals to the communication unit 14 when the first detection unit 11 detects that the cover 7 is in the closed position covering the power button 61 and the change button 62. Therefore, when the cover 7 is in the closed position covering the power button 61 and the change button 62, the communication unit 14 does not communicate with the oxygen concentration device body 2, thus suppressing the power consumption of the remote control 3. As a result, the battery life of the 8 can be improved.

[0086] (3) The remote controller 3 of the above embodiment also includes a second detection unit 12, which detects the gripping state of the main body 4 when gripped by the user. The control unit 15 outputs a command signal based on the detection results of the first detection unit 11 and the second detection unit 12. According to this structure, the control unit 15 outputs a command signal to the communication unit 14 only when the second detection unit 12 detects the gripping state of the main body 4, even when the first detection unit 11 does not detect the closed position of the cover 7. Therefore, even if the cover 7 is in the open position, the communication unit 14 will not communicate with the oxygen concentration device main body 2 before the user grips the main body 4, thus further suppressing the power consumption of the remote controller 3. As a result, the life of the battery 8 can be further improved.

[0087] (4) The second detection unit 12 in the above embodiment is an acceleration sensor. According to this structure, the gripping state of the main body 4 can be easily detected by the acceleration sensor 12.

[0088] (5) In the above embodiment, the main body 4 is formed to be relatively long in the vertical direction (one direction), and the acceleration sensor 12 is provided at the upper end (upper end) of the main body 4 in the vertical direction. According to this structure, when the user grasps the main body 4, the acceleration at the upper end of the main body 4 is greater than the acceleration at the middle part of the main body 4 in the vertical direction. As a result, the grasping state of the main body 4 can be detected more easily by the acceleration sensor 12.

[0089] (6) The first detection unit 11 in the above embodiment includes: a magnet 11a disposed on the cover 7; and a magnetic sensor 11b disposed on the main body 4, which detects the magnetic force of the magnet 11a when the cover 7 is in the closed position.
