FIGS. 5 to 7 are time charts showing the relationship between the humidity display update and the blower when the humidifier is turned on.

FIG. 5 is a time chart showing the relationship between the humidity display update and the blower when the power is turned on (for example, when the power plug is inserted into the power outlet) and the bulk switch is turned on. When the bulk switch 31 is turned on when the power is turned on, the blower 7 starts operating,
At the same time, the humidity sensor 26 detects and reads the humidity. The read humidity value is an unstable value because the power-on voltage fluctuates and the variable resistance of the humidity sensor 26 itself is not stable. Next, after a lapse of T1 time (after about 5 seconds), the humidity is read. This read humidity value is
The humidity of the air in the humidifier 2 is detected, and there may be a difference in humidity between the humidity in the humidifier 2 and the room humidity. In this case, the humidity is different from the room humidity.

Next, after a lapse of T2 time (about 1 minute),
Read the humidity. The value of the read humidity has been operating the blower 7 for T2 time (about 1 minute) or more, and the air near the humidity sensor 26 is almost the same as the indoor air by introducing the indoor air. At this time, if the humidity in the chamber is detected, it is possible to detect and read the humidity substantially matching the indoor humidity. After detecting this humidity, the blower 7 is stopped.

Thereafter, the humidity is detected and read once every Ts time (about 5 minutes), and the change in the room humidity is monitored.
In accordance with the periodic detection and reading of the humidity, the blower 7 is operated before T2 time (about 1 minute) at the time of the detection to take in the indoor air into the chamber to detect a humidity closer to the indoor humidity. is there.

FIG. 6 is a time chart showing the relationship between the humidity display update and the blower when only the bulk switch is turned on without humidifying operation after the power is turned on.

The blower 7 starts operating at the same time when the bulk switch 31 is turned on (ON), and at the same time, the humidity sensor 2
6 detects and reads the humidity. Next, after a lapse of time T1 (after about 5 seconds), the humidity is detected and read. Further, the blower 7 is operated for T2 time (about 1 minute) when the inside humidity matches the room humidity, and the humidity is detected and read. In this way,
Humidity closer to room humidity can be detected and read. After detecting the humidity, the blower 7 is stopped. Hereafter, T
The humidity is detected and read once every s hours (about 5 minutes), and the room humidity is displayed.

FIG. 7 is a time chart showing the relationship between the humidity display update and the blower when the bulk switch is turned on during the humidification operation. Turn on the bulky switch 31 (O
N) Then, the blower 7 starts operating at the same time, and at the same time, the humidity sensor 26 detects and reads the humidity. Next, after a lapse of time T1 (after about 5 seconds), the humidity is detected and read. Further, the blower 7 is operated and the humidity is read until T2 time (about 1 minute) when the inside humidity matches the room humidity. After detecting the humidity, the blower 7 is stopped, and thereafter, every Ts time (about 5
Minutes), and reads and displays the change in indoor humidity.

As described above, when the upright switch 31 is turned on when the power is turned on, or when the upright switch 31 is turned on while the humidification operation is stopped in a state where the humidification is not displayed, the humidity data is first read temporarily. , T1 hours and T2 hours later, the humidity data is updated. During that time, the blower 7 is operated.

By doing so, the room air is taken into the chamber, the air inside the chamber is replaced with the room air, and the humidity is detected and read. Therefore, it is possible to read the humidity closer to the room humidity. After that, the humidity data is updated in the Ts time cycle, and the blower 7 is turned on for T2 hours before each time.
Since the operation is performed for two hours, it is possible to read the humidity closer to the indoor humidity.

FIG. 8 is a time chart showing the relationship between the humidity display update and the blower when the humidifying operation is started with the bulk switch on. In the figure, before the start of the humidification operation, the bulk switch 3
1 is turned on, the humidity is detected and read, and the humidity is read after T1 and T2 hours. Thereafter, the indoor humidity is detected and read every time Ts elapses.

During this time, the blower 7 is operated for T1 and T2 from the time when the humidity is first detected to stop the operation. Thereafter, the humidity is periodically detected, and the blower 7 is operated for T2 hours before T2 of the detection.

Next, when the humidification operation is started, the heater 2
The energization to 2 is started. FIG. 9 is a time chart showing the relationship between the set humidity and the indoor humidity when the humidifying operation is performed.
When the humidification operation is started and the difference is large from the difference between the room humidity and the set humidity, the heater 22 is set to the strong operation, the room is humidified, and the room humidity increases. When the humidification of the room progresses and the difference becomes small, the heater 22 is set to the weak operation to humidify the room. When the indoor humidity reaches the set humidity, the power supply to the heater 22 is stopped, the indoor humidification is stopped, and the humidification is on standby. When the time elapses and the indoor humidity decreases, the power supply to the heater 22 is started again.

In FIG. 8, the blower 7 is operated in conjunction with energization of the heater 22, and is operated until the heater 22 is de-energized. Further, immediately after the heater 22 is stopped, the heater 22 is operated for T4, and the air in the chamber is convected so that the air in the chamber does not rise due to the residual heat after the heater 22 is stopped.

Regarding the update of the humidity, the humidity is detected and read in the cycle of the time Ts regardless of the energization timing of the heater 22.
Then, when the blower 7 is stopped, the blower 7 is controlled to operate before the time T2 when the humidity is detected.

FIG. 10 is a time chart showing the relationship between the humidity display update and the blower when the humidification operation is stopped with the bulk switch on. When the humidification operation is stopped, the energization of the heater 22 is stopped, and the blower 7 stops after the operation for T4 time. Since the reading of the humidity is performed even after the humidification operation is stopped, the detection of the humidity is performed in the cycle of the time Ts. By operating the blower 7 for a time T2 before the time T2 when the humidity is detected, it is possible to detect and read the humidity closer to the room humidity.

In the description of FIGS. 5 to 10, the blower 7 is always operated when detecting and reading the humidity, but the blower 7 is not always operated. The humidifier 2 is often used in the cold winter season, and the operation of the blower 7 also lowers the temperature of the water in the heating tank 21 and reduces the rate of generation of steam generated by heating with the heater 22. When the indoor humidity is lower than a very low predetermined value, the humidity is updated without operating the blower 7. Thereby, it is possible to prevent the water temperature of the heating tank 21 from dropping due to the blower 7 and prevent deterioration of the rising efficiency during the humidification operation.

FIG. 11 is a flowchart showing the operation of the blower of the humidifier in the present embodiment. Note that FIG. 11 does not describe the time of detecting the humidity, but detects and reads the humidity when the initial counter Cf and the cycle counter Cs count.

In step S1, it is determined whether or not the power of the humidifier 2 has been turned on for the time T1 (step S2) or more or the time T2 (step S3) or more. 7 is operated (step S4) and then stopped (step S5). If the humidification operation is started during that time (step S24), the humidification operation is performed. Next, the process proceeds to step S6 to determine whether or not the humidifying operation is being performed. If the humidifying operation is being stopped, the process proceeds to step S7 to determine whether or not the humidifying operation is being performed. If the humidifying operation has been performed (in step S28, the heat radiation counter C
e is set), T4 time (step S21)
The blower 7 is operated (step S20), and after the elapse of the time T4, the blower 7 is stopped (step S22), and the radiation counter Ce is cleared (step SS23). If it is determined in step S7 that the humidification operation has not been performed or that the time T4 has elapsed, the process proceeds to step S8, and it is determined whether or not the mode is the bulk mode (the bulk switch 31 is ON). When the humidification operation is stopped and the mode is the bulk mode,
As shown in (5), when the bulk switch 31 is turned on, the counting of the initial counter Cf is started, and the blower 7 is operated during this time (steps S9 to S11, S19).

Next, the flow shifts to step S13, where it is determined whether or not the detected humidity is equal to or more than a specified value (α%). After the humidity is equal to or higher than the specified value and the initial counter Cf ends, the cycle counter Cs starts counting.
When it is time to operate s (Ts minus T2 hours before the start of counting of the period counter Cs) (step S14), the blower 7 is operated (step S1).
5). Then, when the blower 7 operates for the time T2 and the time Ts elapses (step S16), the cycle counter Cs is cleared, and the process proceeds to step S18, where the blower 7 is stopped. Thereafter, when it is determined in step S29 that the power is not turned off, the operation returns to the state before step S6, and the operation of the blower 7 is repeated.

When it is determined in step S29 that the power has been turned off, the humidifier 2 is stopped (EN).
D).

In step S8, when the humidification operation is stopped and the upside down switch 31 is OFF, the process shifts to step S12, the microcomputer 38 resets the initial counter Cf, shifts to step S18, and keeps the blower 7 stopped. I do. Thereafter, the operation returns to the state before step S6, and the operation of the blower 7 is repeated.

On the other hand, if it is determined in step S6 that the humidifying operation is being performed, it is determined in step S25 whether or not the heater 22 is turned on.
7 and the blower 7 is operated. Then, the process proceeds to step S28 to reset (reset) the radiation counter Ce, and after the heater 22 is stopped, the blower 7 is operated for a predetermined time (T4
Time) to continue the operation. By operating the blower 7 for a certain period of time (T4 time), it is possible to disperse the residual heat of the heater 22 after the heater 22 is stopped and to stabilize the temperature inside the chamber.

Thereafter, the operation returns to the state before step S6, and the operation of the blower 7 is repeated. Only at the start of the humidification operation, as shown in FIG. 7, the timer 43 of the microcomputer 38 counts the initial counter Cf, and the blower 7 operates.

In step S25, the heater 2
If 2 is not the ON condition, the process proceeds to step S26,
It is determined whether or not the blower 7 is in the OFF condition. Blower 7
If is the OFF condition, the process proceeds to step S18 and the blower 7
Is turned off, and if the condition is not OFF, step S2
7. The process proceeds to step S28.

Although the present invention has been described based on one embodiment, the present invention is not limited to this.

In this embodiment, the steam humidifier has been described as an example, but the type of the humidifier is not limited to the steam humidifier. Any humidifier may be used as long as the water in the heating tank is heated by the heating means to generate steam, and the steam is used to humidify the interior of the room or the like.

[0050]

According to the present invention, when the room humidity is low and the room humidity does not reach the predetermined humidity, the humidity value is updated while the blower is stopped. Generated noise and vibration are suppressed, and a decrease in the temperature of the water in the heating tank is suppressed, so that deterioration of the humidification efficiency of the humidifier is prevented.

When the humidity display switch is turned on or when the humidification operation is started, the humidity is temporarily detected and read.
Next, by operating and operating the blower for a certain period of time and then detecting and reading the humidity, the indoor air is taken into the humidifier and stabilized, and the humidity closer to the humidity of the indoor air can be detected. Further, thereafter, the humidity is detected at a fixed cycle time, and before a certain time before the humidity detection, the blower is operated to detect and read the humidity.
