A humidifier according to one embodiment of the present invention is a humidifier that discharges water vapor or mist into a room and humidifies the water. A blower means for sending, a humidifying means for evaporating or spraying the supplied water, humidifying the sucked air, a water amount detecting means for detecting the amount of water stored in the water supply tank, and stopping the operation after a set time has elapsed. A timer setting means for setting a timer time to be turned off, a humidity detecting means for detecting indoor humidity, a remaining time calculating means for calculating a remaining time until the timer expires, and a water amount detecting means The humidification amount calculation for calculating the humidification amount for continuing the humidification for the remaining time from the amount of water in the tank, the indoor humidity detected by the humidity detection means, and the remaining time calculated by the remaining time calculation means. And the humidifying means for controlling the humidifying amount to be the amount of humidification calculated by the humidifying amount calculating means, and continues the humidification for the time set by the off timer, It is possible to provide a humidifier that maintains a desired humidity even when the humidity changes due to environmental changes (such as temperature).

The humidifying amount calculating means has strong, medium and weak humidifying amounts. When the humidity detected by the humidity detecting means is 0 to 39%, the humidifying amount is strong, and when the humidity is 40 to 60%, the humidifying amount is medium. In the case of 61 to 100%, a weak humidification amount may be calculated.

Further, the humidifying means is composed of a humidifying filter that sucks up the supplied water and passes the sucked air, and an air volume control means for controlling the air volume by the air blowing means, and the air volume control means controls the air blowing volume. The humidification amount may be controlled by the above. With this configuration, the indoor humidity during the off timer operation can be maintained at 40 to 60%.

In addition, the maximum humidification amount is obtained by dividing the water amount detected by the water amount detection unit by the remaining time calculated by the calculation time calculation unit, and the humidification unit calculates the humidification amount calculated by the humidification amount calculation unit as the maximum humidification amount. When the amount is exceeded, the maximum humidification amount may be operated . With this configuration , humidification can be continued for the time set by the off timer.

  The present embodiment will be described below with reference to the drawings.

(Embodiment 1)
The configuration of the first embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 1, the humidifier according to the present embodiment sucks up the water stored in the humidifier body 1 with the humidifying filter 5 and drives the air blowing means 7 to pass the room air through the humidifying filter 5. It is humidified and supplied to the room again.

  The humidifier body 1 includes a suction port 2 that opens into the room and sucks air, a dust collection filter 9, and a ventilation path 3. Further, the humidifier body 1 has a water supply tank 4, a humidifying filter 5, an air blowing means 7, and a humidifying path 6 through which humidified air is passed.

  The water supply tank 4 stores water to be humidified, supplies water to a humidifying filter 5 described later, and is accommodated in the humidifier body 1 so as to be able to be taken in and out. The water amount detection means 10 is constituted by a pressure sensor, a strain sensor, or the like for detecting the total weight of the water supply tank 4 including the stored water. The humidifying filter 5 performs humidification by sucking up water from the water supply tank 4, passing indoor air, and adding moisture to the air.

  Further, the humidification path 6 is a path through which indoor air humidified by the humidification filter 5 passes. The air blowing means 7 is for sucking indoor air, humidifying it, and then blowing it out into the room for circulation. Here, in the present embodiment, the humidification amount is adjusted by adjusting the amount of air passed through the humidification filter 5. And the humidified air is discharged | emitted from the blower outlet 8 indoors.

  Moreover, the humidity detection means 11 is provided in the vicinity of the suction inlet 2, and detects indoor humidity. The turn-off timer setting means 12 sets a turn-off timer time by a user's switch operation, and sends the set turn-off timer time to the control calculation unit 13. As will be described later, the control calculation unit 13 includes a remaining time calculation unit 14, a humidification amount calculation unit 15, and an air volume control unit 16, and controls the air volume so that the calculated humidification amount is obtained.

  FIG. 2 is a block diagram showing a configuration of the control calculation unit 13 in the embodiment of the present invention.

  The remaining time calculating means 14 calculates the remaining time until the turning timer operation set by the turning timer setting means 12 stops. The humidification amount calculation means 15 is based on the amount of water in the water supply tank 4 detected by the water amount detection means 10, the indoor humidity detected by the humidity detection means 11, and the remaining time of the off timer operation calculated by the remaining time calculation means 14. The humidification amount for maintaining the desired humidity is calculated while continuing the humidification operation. Here, the desired humidity is a target humidity set by an operation unit provided in the humidifier body 1 or a preset target humidity. The air volume control means 16 controls the output of the air blowing means 7 so that the calculated humidification amount is obtained.

  FIG. 3 is a diagram illustrating a flowchart of the off timer operation in the embodiment of the present invention.

  When the user sets the cutoff timer by the cutoff timer setting means 12, the cutoff timer operation is started, and the flow shown in FIG. 3 is started. In the off timer operation according to the present embodiment, as described above, the humidification amount control is performed so that the target humidity is reached. Hereinafter, a description will be given with reference to FIG.

  First, in step S1, the cutoff timer setting unit 12 sets the cutoff timer setting time. In step S <b> 2, the water amount of the water supply tank 4 is detected by the water amount detection means 10. The water amount detection means 10 is provided at the bottom of the storage portion of the water supply tank 4. For example, when a pressure sensor is used as the water amount detection means 10, the water amount detection detects the pressure when the water supply tank 4 is stored, and calculates the weight from this pressure. By subtracting the weight (fixed value) of the water supply tank 4 from the obtained weight, the amount of water put in the water supply tank 4 is calculated. In step S <b> 3, the humidity detection means 11 performs indoor humidity detection. In step S4, the remaining time calculation means 14 calculates the remaining time of the off timer. In step S5, the humidification amount calculation means 15 calculates the amount of water detected by the water amount detection means 10, the indoor humidity detected by the humidity detection means 11, and the remaining time of the turn-off timer calculated by the remaining time calculation means 14. While maintaining the timer operation, calculate the humidification amount to achieve the optimum humidity. In step S6, the air volume control means 16 controls the air volume by adjusting the output of the motor built in the air blowing means 7 so that the humidification quantity calculated by the humidification quantity calculation means 15 is obtained. In step S7, it is determined whether the set-off timer has elapsed. When the set time has elapsed, the operation is stopped. adjust.

  In the cut-off timer operation in the present embodiment, the indoor humidity of 40% to 60% that makes the occupant feel comfortable is set as the target humidity. The goal is to maintain this humidity range until the end timer operation ends.

  Therefore, the humidification amount calculation means 15 calculates the humidification amount for maintaining the indoor humidity 40% to 60%. Here, in the present embodiment, strong, medium and weak humidification amounts are output as the humidification amount.

  Specifically, the humidification amount calculation means 15 is a strong humidification amount when the humidity detected by the humidity detection means 11 is 0 to 39%, a humidification amount when it is 40 to 60%, and a case when the humidity is 61 to 100%. Calculates a weak humidification amount. However, when the amount of water detected by the water amount detection means 10 divided by the remaining time calculated by the remaining time calculation means 14 is the maximum humidification amount, and the humidification amount calculated by the humidification amount calculation means 15 exceeds the maximum humidification amount. The maximum humidification amount is used as a calculation result. Then, the air volume control means 16 controls the air blowing amount of the air blowing means 7 so as to be the humidifying amount calculated by the humidifying amount calculating means 15. And the process from the humidification amount calculation by the humidification amount calculation means 15 to the air volume control by the air volume control means 16 is repeatedly performed until the off timer operation expires. Therefore, comfortable humidity can be continued during the operation time set by the turn-off timer setting means 12. Furthermore, since the humidification amount calculation means 15 always confirms the indoor humidity, the remaining water amount, and the remaining time of the timer operation during operation, it is possible to prevent excessive humidification. In addition, the amount of humidification can be changed in response to changes in humidity due to environmental changes (temperature, etc.), and the room humidity during the timer operation can be controlled to be as high as possible.

  As described above, according to the humidifier according to the present embodiment, for example, at the time of going to bed or when heating is turned off, the room temperature is lowered, but the humidification amount remains as it is, so that it is not excessively humidified. In addition, it is possible to realize a cut-off timer operation that maintains a humidity of 40% to 60% that the occupant feels comfortable against a humidity change due to a change in the indoor environment (such as temperature).

  In this embodiment, the filter type humidifier has been described. However, the present invention can also be applied to an ultrasonic type or a steam humidification.

  Further, the humidification amount output from the humidification amount calculation means 15 may be a continuous value in accordance with the capability of the humidifier, and the air volume of the blower means 7 may be controlled.

  The humidifier according to the present invention can be used for humidity control or the like of a general household off timer operation.
