According to the increasing affluence of the society and the continuous improvement of people's quality of life, air-conditioners, electric heaters and dehumidifiers have gradually become the necessary home appliances for many families in all corners. Especially for the subtropical and tropical regions in the summer season, most indoor homes will be equipped with air-conditioners, so that it is a long and hot summer.

Nowadays, when using air-conditioning, the air in the room is heated and exchanged to reduce the temperature and then blown back into the room to reduce the indoor temperature. However, in the process of indoor air heat exchange and cooling, if the indoor air is colder, The air in the room is drier, which is easy to cause discomfort to the human body. In addition to causing discomfort in the air, when the air is used in the laboratory, the air that is too dry may cause the data detected by the experimental instrument to be inaccurate. In order to improve the accuracy of the experimental results, a humidifier is usually used. To increase the humidity in the laboratory to ensure useful data when testing the instrument. However, the traditional humidifier still has the following shortcomings, and there is a need for improvement:

Please refer to FIG. 1 and FIG. 2 . FIG. 1 illustrates the humidity controller 10 of the present embodiment, and FIG. 2 illustrates the operational relationship of related components of the humidity controller 10 . The humidity controller 10 includes a microcontroller 11 , a container tank 12 , a setting module 13 , an air motor 14 , a liquid level sensor 15 , a humidity sensor 16 , and a display 17 . The microcontroller 11 mainly receives the signals provided by the setting module 13, the liquid level sensor 15 and the humidity sensor 16, and the microcontroller 11 is also connected to a driver 111. The driver 111 is in accordance with the instruction of the microcontroller 11. Operation. The container tank 12 is filled with a liquid water 121. The liquid water 121 occupies about 6 to 7 minutes of the inside of the tank body, and the container tank 12 has an air outlet 122 near the top surface, and the air outlet 122 is the inside of the container tank 12. The main outlet of the air. In addition, the setting module 13 is disposed on the outer surface of the container body 12. The setting module 13 is, for example, a numerical setting panel having a numeric button of 0-9 on the surface, and the user of the humidity controller 10 can set the mode. The group inputs a first set value and a second set value, and the second set value is greater than the first set value, the first set value is, for example, "60", and the second set value is, for example, "75". Then, the module is set and the first set value "60" and the second set value "75" are transmitted to the microcontroller 11, and the microcontroller 11 sets the first set value "60" and the second set value again. 75" is displayed on the display. In addition, the air motor is connected to the driver, and the air motor is provided with an injection line 141 connected to the bottom surface of the interior of the container body 12. The driver 111 drives the air motor 14 according to the instruction of the microcontroller 11, and the driven air motor 14 will eject the airflow from the injection line 141 (see Figure 3). Here, in the case where the liquid water 121 is sufficient, the injection line 141 located on the bottom surface of the container tank 12 is flooded by the liquid water 121. In addition, the liquid level sensor 15 is a top surface provided on the periphery of the container body 12. The liquid level sensor 15 extends a plurality of liquid level sensing bars 151 into the container body 12, and the lengths of the liquid level sensing bars 151 are different, and the liquid level sensing bars 151 can detect The water level of the liquid water 121. Thereafter, the liquid level sensor 15 converts the detected water level height into a water level height value and transmits it to the microcontroller 11. In addition, the humidity sensor 16 is also disposed on the outer surface of the container body 12. The humidity sensor 16 mainly detects the ambient humidity (relative humidity) outside the humidity controller 10, and converts the ambient humidity into a humidity value. To the microcontroller 11, the microcontroller 11 displays the water level height value transmitted from the liquid level sensor 15 and the humidity value transmitted from the humidity sensor 16 on the display 17. In the above, the driver 111 drives the air motor 14 in accordance with the instruction of the microcontroller 11, and the driven air motor 14 ejects the airflow from the injection line 141.

Please refer to FIG. 3 , which is a schematic diagram of the air motor 14 of the humidity controller 10 when it is driven. When the humidity value received by the microcontroller 11 (the humidity value is, for example, "50") is less than the first set value "60", the microcontroller 11 causes the driver 111 to drive the air motor 14 to cause the air motor 14 to be ejected. Line 141 ejects a stream of gas. Then, the air bubbles generated by the jetted air flow entrain the moisture in the entire container body 12, and then the moisture (water vapor) will be discharged from the air outlet, so that the external environment humidity (relative humidity) ) will improve.

Referring to FIG. 1 , when the humidity value received by the microcontroller 11 (the humidity value is, for example, “78”) is greater than the second set value “75”, the microcontroller 11 causes the driver 111 to stop driving the air motor 14 . The air motor 14 does not eject the airflow from the injection line 141, so the external environmental humidity (relative humidity) does not continuously increase. Compared with the conventional humidifier, the humidity controller 10 of the present embodiment is provided with a humidity sensor 16 for detecting relative humidity on the outside of the body, and the humidity sensor 16 detects the indoor humidity. When the relative humidity exceeds the second set value "75", the humidification function of the humidity controller 10 is stopped, so that the indoor air is excessively wetted, and the surface of the object in the room is dew condensation.

Referring to FIG. 4, a humidity controller 20 of another embodiment is illustrated. The humidity controller 20 further includes an alarm 28 which is also disposed on the outer surface of the container body 12. When the humidity controller 20 When the humidifying operation is performed, the liquid water 121 in the container tank 12 is consumed. If the water level value of the liquid water 121 is lower than a critical value (for example, 15 cm), the alarm 28 sounds an alarm. In this way, the user can be reminded to add liquid water 121 to the container tank 12. In the above, the user can also know the water level of the liquid water 121 via the water level height value of the display 17. The user then decides whether or not to add liquid water 121.

In summary, the advantages of the humidity controller 10 of the present embodiment are as follows:

(1) It has an accurate humidity electronic control structure, which will not cause condensation on the surface when the dew point of the air is higher than the surface temperature of the laboratory instrument due to excessive humidification.

(2) The humidity controller 10 has a simple mechanical structure and low assembly and production costs.

(3) The humidity controller 10 has a setting function, and the first set value and the second set value set by the setting module 13 can achieve the desired humidity in the indoor environment.
