DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an additional function of a humidifier.

[0002]

2. Description of the Related Art Conventionally, in a small humidifier used for home use, a certain amount of water is temporarily stored in a storage tank from a tank.
The humidity in the room is detected by a plurality of humidity sensors arranged so as to be in direct contact with the room air and compared with the preset set humidity.If the humidity is lower than the set humidity, the water in the storage tank is transferred to the heating tank. Then, the heater of the heating tank is energized to generate steam, and the steam is released into the room by the blower. When the humidity exceeds the set humidity, the water supply from the storage tank is stopped, the heater of the heating tank is turned off, and the evaporation is stopped. In this way, the indoor humidity is kept constant. In this case, the blower is operated at all times so that the temperature in the heating tank does not increase, and the temperature of the steam to be blown is reduced. Since the blower is operated even while the humidification function is stopped, wind noise caused by the fan of the blower is anxious in a quiet bedroom or the like where the baby sleeps, causing a problem of hindering sleep.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and changes wind noise generated by a fan of a blower into environmental sound having a rhythmic feeling and a calming effect for an infant, thereby maintaining a good sleep. It is intended to provide an additional function of the humidifier.

[0004]

In order to achieve the above object, the operation of the blower is intermittently performed at a constant rate for a predetermined time, so that a driving sound having a rhythmic feeling is transmitted, and the infant or child close to the intrauterine sound is transmitted. Now generates a soothing environmental sound. Also, the humidifier is provided with a mode selection switch that selects the intermittent operation of the blower and the humidifying function, and when performing the normal operation and the humidifying function of the blower at the same time, when performing the intermittent operation and the humidifying function of the blower at the same time, only the intermittent operation of the blower Separated into the modes when performing, and select the mode according to the usage state.

[0005]

According to the above construction, by operating the blower intermittently at a fixed number of times (for example, 85 times per minute) in a fixed time, the wind noise caused by the fan of the blower can be reduced to a driving sound having a rhythm close to the womb sound. To increase the sedative effect of infants at bedtime. In addition, when used in offices during the daytime, this function should be stopped because the wind noise from the fan is disturbed by the ambient sound and is not bothersome. I try to prevent that from happening.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of the present invention. A humidifier control unit 2 for controlling the operation of a humidifier 1 includes a set humidity input device 3 for inputting a preset indoor humidity and a detection of the indoor humidity. A plurality of humidity sensors 4 and a mode changeover switch 6 for switching operation modes of the humidifier 1 and the blower 5 are provided. The humidifier control unit 2 controls the operation of the humidifier 1 and the blower 5 by a water supply control unit 7 that generates humidified steam, a heater control unit 8, and a blower control unit 9 that sends out the generated steam to the room. The operating state is displayed on the display unit 10. When the humidifier 1 is started to operate, the humidity in the room is detected by the plurality of humidity sensors 4 and sent to the humidifier control unit 2, and the humidity is compared with the set humidity set by the set humidity input device 3 in advance. When the humidity is lower than the set humidity, the water in the water storage tank is guided to the heating tank, the heater is energized, and the heater control unit 8 evaporates the water at a temperature corresponding to the difference between the set humidity and the indoor humidity. To send it indoors. The water supply control unit 7 detects the water level of the water storage tank, automatically stops the operation of the humidifier, and displays the replenishment of the water in the tank on the display unit 10 to prevent an accident such as empty heating of the heater. I try to prevent it.

FIG. 2 is a circuit block diagram showing details of the blower control unit 9 of the present invention.
A control signal is sent from a control signal generation circuit 14 to the gate terminal of the triac 13 to control the operation of the blower 5. The control signal generating circuit 14 is supplied with DC power from a transformer 15 and a rectifier circuit 16 connected in parallel with the power
Based on the setting, a predetermined DC voltage or pulse signal is generated, sent to the gate terminal of the triac 13, and the triac 13 is switched to control the operation of the blower 5. FIG.
Indicates the setting of the mode changeover switch 6 and the state of the gate signal of the triac 13. In the case of a normal humidifying operation, a predetermined DC voltage is applied to the gate terminal of the triac 13, and the blower 5 is turned on and off in the humidifying operation. The triac 13
A pulse signal is sent to the gate terminal of the first embodiment.
According to the literature, infants up to three months old (15
To the mother's maternal aortic intrauterine sound (approximately
85 times), the response was almost 1 until 2 months after birth.
It has been confirmed that crying stops at 00% and about 50% in the first three months of life. In order to operate the blower 5 intermittently and generate a driving sound having a sedative effect for an infant close to the womb sound, about 85 min / min.
A rectangular wave of ON 600 mS and OFF 100 mS is used as a pulse signal to be sent to the gate terminal so as to be intermittent at the rate of the number of times.

As described above, by operating the blower 5 intermittently at a fixed number of times in a certain time, a driving sound close to the womb sound having a rhythmic feeling is generated, and a sedative effect is provided to the infant. Similarly, by intermittently energizing the heating heater of the heater 1, the evaporating sound during evaporation is generated at a certain number of times in a certain period of time to generate an evaporating sound having the same rhythmic feeling and to provide a calming effect at bedtime. Can bring.

[0009]

As described above, according to the present invention, by operating the blower built in the humidifier intermittently at a certain number of times in a certain period of time, it is possible to generate a driving sound close to the womb sound, and Infants can be given an environmental sound with a sedative effect.
