The LED driving unit 82 drives the LEDs 83 mounted on the lighting board 55.
With respect to the LED driving section 82, the control section 81 is always electrically connected to the power supply section 85. On the other hand, the motor 48 is electrically connected when the switch 80 is in the "on" state, and is electrically disconnected when the switch 80 is in the "off" state. That is, even if the power cord 25 is connected to the power supply connection unit 32, the power supply unit 85 is in a state in which power can be supplied, and the control unit 81 itself is connected to the power supply unit 85, and power is not supplied to the motor 48 until the switch 80 is in the "on" state.
(mounting method of air purifier 1)
A method of mounting the air cleaner 1 configured as described above on a ceiling will be described.
Step 1: the body support member 21 is mounted on a ceiling decorative ring 12 provided on the ceiling 11 (refer to fig. 3). The body support member 21 is fixed to the ceiling trim ring 12 by screws 23.
Step 2: it is confirmed that the state of the switch 80 provided on the upper surface portion of the main body portion 22 is "off".
And step 3: the main body 22 is attached to the main body support member 21. At this time, the main body 22 is raised to the position of the ceiling 11, moved toward the main body support member 21 in parallel with the lower surface of the ceiling 11 (refer to fig. 4), and the support member fitting portion 31 of the main body 22 is fitted to the main body support member (refer to fig. 5).
And 4, step 4: the body portion 22 is rotated so that the fitting convex portion 31a2 of the upper plate portion 31a of the support member fitting portion 31 is fitted into the fitting hole 21b of the flange portion 21a of the body support member 21. Thereby, the main body 22 is fixed so as not to rotate.
And 5: the power supply line 25 extending from the ceiling decorative ring 12 and led from below the main body support member 21 to the upper surface portion of the main body 22 is connected to the power supply connection portion 32 of the main body 22 (refer to fig. 5).
Step 6: the power cord cover 24 is attached to the main body portion 22 so as to cover the power cord 25 (see fig. 6).
And 7: finally, the switch 80 provided on the upper surface portion of the main body portion 22 is set to the "on" state (refer to fig. 5).
The main body 22 can be detached from the main body support member 21 in a reverse order to the above-described order of attaching the main body 22 to the main body support member 21.
(advantages of air purifier 1)
In the air cleaner 1 of the present embodiment, the main body 22 is provided with a switch 80 operable by an operator to switch between connection (conduction) and disconnection (non-conduction) of the motor 48 of the blower 42 and the power supply unit 85. Thus, by setting the switch 80 to the "off" state until the installation is completed, it is possible to prevent the fan 47 from starting a normal rotation operation, which is not an operation intended by the operator, once the power cord 25 is connected to the power supply connection portion 32 of the main body portion 22. The timing at which the power supply line 25 is connected to the power supply connection portion 32 corresponds to the timing at which the power supply portion 85 is electrically connected to the ceiling decorative ring 12.
In the present embodiment, the switch 80 is provided on the upper surface portion of the main body 22, but the installation is not limited to the upper surface portion. But is preferably provided at a position that is not visible when viewed from below the ceiling-mounted air cleaner 1.
(alternative example 1)
A modification of the present embodiment will be described with reference to the drawings. As shown in fig. 10, the air cleaner 1A according to the modified example is provided with a cutting piece 86 which cuts off the electrical connection between the motor 48 and the power supply unit 85 in the inserted state and electrically connects the two by pulling out the cutting piece, instead of the switch 80. In step 7, the cut piece 86 is pulled out instead of the switch 80 being turned "on".
In this configuration, once the cutting piece 86 is pulled out, the motor 48 and the power supply unit 85 cannot be disconnected from each other, but there is an advantage in that the configuration can be made at low cost compared to the configuration in which the switch 80 is provided.
(second embodiment)
Other embodiments of the present invention will be described based on the drawings. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.
In the air cleaner 1(1A) according to the first embodiment, the main body 22 is provided with a switch 80 (a cut-off piece 86) for switching between connection (conduction) and disconnection (non-conduction) between the motor 48 of the blower 42 and the power supply unit 85.
In the air cleaner 1B (see fig. 1) of the present embodiment, a human detection sensor is used instead of the switch 80 (the cut piece 86). The human detection sensor detects the presence of a human in a room in which the air purifier 1 is disposed. The air cleaner 1 of the present embodiment has an automatic lighting mode. The automatic lighting mode is a mode in which the lighting unit 45 is turned on when the human detection sensor detects a person in a room in which the air cleaner 1B is installed, and the lighting is automatically turned off after a certain time has elapsed since the turning on.
Fig. 11 is a block diagram showing a main configuration of a control system of the air cleaner 1B. As shown in fig. 11, a human detection sensor 84 is connected to the control unit (blocking unit) 81B of the air cleaner 1B, instead of the switch 80.
Fig. 12 is a flowchart showing a flow of connection processing between the motor 48 of the blower 42 and the power supply unit 85, which is executed when the control unit 81B of the air cleaner 1B first turns on the power supply provided by the power supply unit 85.
The power supply section 85 is in a state of being able to supply power by connecting the power supply line 25 and the power supply connection section of the main body section 22. Thereby, the power supply section 85 starts supplying power to the control section 81B, the human detection sensor 84, and the LED driving section 82.
The human detection sensor 84 detects the operator who is installing the air cleaner 1B. The control unit 81B repeatedly determines whether or not a person is absent (no person) based on the detection of the person detection sensor 84 (S1).
After the installation is completed, the worker leaves the space where the air cleaner 1B is installed, and the human detection sensor 84 cannot detect the presence of a human. The control unit 81B determines that a person is absent (no person) in the installation space based on the fact that the human detection sensor 84 cannot detect the presence of a person. The control unit 81B determines that a person is absent (no person) when the presence of a person is not detected within a predetermined time after the presence of a person is detected by the person detection sensor 84, for example.
When determining that the person is not present (no person), the control unit 81B connects the motor 48 of the blower 42 and the power supply unit 85 (S2).
With this configuration, the human detection sensor 84 can prevent the fan 47 from starting normal rotation operation, which is not intended by the operator, without providing the switch 80.
In the present embodiment, the initial power supply is performed according to the processing shown in fig. 12. Therefore, the control unit 81B connects the motor 48 of the blower 42 and the power supply unit 85 when it is determined for the first time that a person is absent, based on the detection result of the person detection sensor 84. However, the present invention is not limited to the first determination, and the connection may be performed when the second determination is made that a person is not present.
(third embodiment)
Other embodiments of the present invention will be described based on the drawings. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.
In the air cleaners 1 to 1B of the first and second embodiments, the main body 22 is provided with a switch 80 (a cut-off piece 86) for switching between connection (conduction) and disconnection (non-conduction) of the motor 48 of the blower 42 and the power supply portion 85, or with a human sensor 84.
In the air cleaner 1C (refer to fig. 1) of the present embodiment, by providing a time lag to the connection between the motor 48 and the power supply portion 85, it is prevented that the fan suddenly starts a normal rotation operation or the like which is not intended by the operator.
Fig. 13 is a block diagram showing a main configuration of a control system of the air cleaner 1C. As shown in fig. 13, the opening sensor 80 and the human detection sensor 84 are not connected to the control unit (blocking unit) 81C of the air cleaner 1C.
Fig. 14 is a flowchart showing a flow of connection processing between the motor 48 of the blower 42 and the power supply unit 85, which is executed when the control unit 81C of the air cleaner 1C first turns on the power supply provided by the power supply unit 85.
The power supply section 85 is in a state of being able to supply power by connecting the power supply line 25 and the power supply connection section of the main body section 22. Thereby, the power supply unit 85 starts supplying power to the driving unit 82 of the control unit 81C, LED.
When the control unit 81C first turns on the power supply to the power supply unit 85, it starts a timer and repeatedly determines whether or not a predetermined fixed time (first fixed time) has elapsed since the connection with the power supply unit 85. When determining that the predetermined time has elapsed, the control unit 81C connects the motor 48 of the blower 42 and the power supply unit 85 (S2).
With this configuration, the switch 80 or the human detecting sensor 84 is not required, and the operation of the fan 47 which is not intended by the operator and which starts the normal rotation operation is prevented at the lowest cost.
The fixed time may be, for example, 30 seconds or 60 seconds, taking into consideration the time from the connection of the power supply line 25 to the power supply connection unit 32 until the worker finishes attaching the air cleaner 1C and leaves the air cleaner 1C.
In the present embodiment, the motor 48 of the blower 42 and the power supply unit 85 are connected after a predetermined time has elapsed, and the control unit 81C may control the motor 48 to rotate the fan 47 gradually after the fixed time has elapsed so that the speed of the fan 47 reaches the speed of the rotating operation.
(fourth embodiment)
Other embodiments of the present invention will be described based on the drawings. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.
In the present embodiment, the automatic lighting mode of the lighting unit 45 that can be used in the air cleaners 1 to 1C of the first to third embodiments is described. The automatic light-on mode described in the present embodiment can also be applied to a ceiling lamp to which the blower 42 is not attached.
Fig. 15 is a block diagram showing a main configuration of a control system of the air cleaner 1D. Fig. 15 shows only a part related to the control of the illumination unit 45. The control unit 81D is connected to the human detection sensor 84, the power supply unit 85, the timer unit 90, and the LED driving unit 82.
When the human detection sensor 84 detects the presence of a human, the control unit 81D turns on all the LEDs 83 (on in the first state) using the LED driving unit 82. The control unit 81D returns the counter for measuring the light-on holding time of the timer 90 to the initial value and starts the measurement (reset) every time the human detection sensor 84 detects the presence of a human in all lights-on.
The initial value of the light-on maintaining time T is, for example, 60 seconds. The total lighting of the LEDs 83 means that the lighting can be obtained at normal brightness, and is used to distinguish a warning light of turning off (lighting in the second state) described later. That is, fully on does not mean that all of the LEDs 83 are on at full power.
When the on time of all the lights exceeds the predetermined on-hold time T, the control unit 81D performs an off-notice light (on in the second state) having a lower brightness than all the lights. The light-off advance notice lamp is a lamp-on advance notice lamp for notifying that the light is to be turned off. The light-off prediction time t is, for example, between 7 and 8 seconds.
The control unit 81D starts the light-off advance notice light and starts the calculation by the counter for calculating the light-off advance notice time of the timer unit 90. In the light-off advance notice lamp, if the human detection sensor 84 detects no human and a predetermined light-off advance notice time t (second fixed time) elapses, the light-off is performed. On the other hand, when the human detection sensor 84 detects the presence of a human, the lighting is returned to all the lights. That is, the counter for calculating the lighting maintenance time is returned to the initial value, and the lighting maintenance time T is calculated from this time point.
Further, the control unit 81D includes a lighting maintaining time updating unit 81D1 that updates the lighting maintaining time T. The lighting-on maintaining time updating unit 81D1 is configured to calculate the number of times of extension corresponding to the number of times of return to full lighting (number of times of return) for detecting the presence of a human being during the period of performing the pre-lighting-off notification, in units of the number of times from the start of full lighting to the time of turning off the lighting. Then, the lighting maintaining time updating unit 81D1 updates the lighting maintaining time T so that the average value of the number of returns or the maximum value of the number of extensions falls within a predetermined range of values.
Fig. 16 is a flowchart showing a flow of the light-on maintaining time updating process executed by the control unit 81C of the air cleaner 1D. When the human detection sensor 84 detects the presence of a human and turns on all of the LEDs 83 in the off state, the processing shown in fig. 16 is executed. In this flowchart, the processing steps of determining that the on-light maintaining time T has timed out and starting the calculation of the off-light advance notice time T are omitted.
The control unit 81D (the light-on maintaining time updating unit 81D1) repeatedly determines whether or not the human presence sensor 84 detects a human presence (S21). When determining in S21 that the presence of a person is detected, the control unit 81D determines whether or not the period is within a warning period (warning time t) during which a warning is being turned off (S22). When it is determined that the off-light advance notice period is present, the control section 81D proceeds to S23, increments the counter for counting the number of extensions by 1, and returns to S21. On the other hand, if it is determined that the time is not within the light-off notice period (i.e., the light-on maintaining time), the process returns to S21 without passing through S23.
When determining in S21 that the presence of a person has not been detected, the control unit 81D determines whether or not the off-light advance notice time t has elapsed (S24). When it is determined in S24 that the light-off advance notice time t has elapsed, the control section 81D proceeds to S25 and calculates the average number of extensions.
The control unit 81D calculates the average extension count, and proceeds to S26 to determine whether the average extension count is, for example, 0.5 or more. Here, if it is determined to be 0.5 or more, the lighting-on maintaining time is increased by 1(S27), and the process is ended. On the other hand, if it is determined in S26 that the average extension count is not 0.5 or more, the routine proceeds to S28, and it is determined whether or not the average extension count is 0.2 or less. Here, if it is determined to be 0.2 or less, the lighting-on maintaining time T is reduced by 1 second (S29), and the process is terminated.
The processing in S25 to S29 will be described by way of specific examples. For example, the lamp-on maintaining time T is 60 seconds, and the number of averaged lamp-on times (the number of lamp-on times is counted from the start of lamp-on to the time of lamp-off in all lamp-on), that is, the number of averaged lamp-on times is 10.
0.5 as the determination criterion of S26 corresponds to the case where five of the ten times of lighting are extended. If the ten-time lighting is extended five times or more, the routine proceeds to S27, and the lighting maintenance time T is increased by 1 second. If the initial value of the lamp-on maintaining time T is 60 seconds, the updating time is 61 seconds. This can avoid frequent occurrence of the advance notice lamp for turning off the lamp in a state where a person is present.
0.2 as the determination reference of S28 corresponds to the case where two of the ten times of lighting are extended. If the ten-time lighting is prolonged twice or less, the routine proceeds to S29, and the lighting-on maintaining time T is reduced by 1 second. When the initial value of the lamp-on maintaining time T is 60 seconds, the lamp-on maintaining time T is updated to 59 seconds. This can avoid the situation where the lamp-on maintaining time T is unnecessarily long and the lamp is meaninglessly turned on in a state where no one is present.
In this example, when the number of times of extension is three or four out of ten times of lighting, it is determined that the lighting maintaining time T is appropriate. That is, the control unit 81D adjusts the lamp-on maintaining time T so that the number of times of lamp-on is extended to 3 to 4 times among ten times of lamp-on. Therefore, the light-on maintaining time can be automatically updated according to the use condition of the user, so that the light-off forenotice is not frequently generated, and the light-on time is not wasted.
Further, instead of the average extension count, the maximum extension count can be obtained. In addition, the present invention can be adjusted to a range more suitable for the use situation of the user than the two schemes.
For example, whether or not the lighting maintenance time T is appropriate is determined based on the maximum number of extensions, and when the lighting maintenance time T is updated, it is preferable to exclude the maximum number of extensions in an abnormal situation such as a case where one lighting is extended five times or more.
Such a technique for updating the lighting time in accordance with the automatic lighting mode is very effective when used for lighting in toilets, bathrooms, hallways, outdoor lights of doors, stairways, and the like.
The lighting device described in patent document 2 is provided with a mode in which all lighting loads (i.e., LEDs) are turned on every time the human presence sensor detects a human presence, and the lighting is turned off in advance to the human by at least two stages of turning off after a predetermined lighting on duration time is exceeded.
However, the lamp-on holding time is fixed to a general value. Further, in order to change the general lighting maintenance time, it is necessary to manually set a lighting maintenance time changeover switch, which is troublesome.
In the case where the light-on maintaining time is short and the advance notice of light-off frequently appears, even if the light-on maintaining time is changed to avoid this, the settable value is a fixed value prepared in advance, and therefore, the time for light-on is inevitably wasted.
In addition, in the case where the light-on maintaining time is long and the light-off notice does not frequently occur, the light-on maintaining time is not changed unless the user finds the case and artificially changes the light-on maintaining time, and therefore, the light-on time is wasted.
