Description

Humidification amount control circuit of air conditioner humidifier

The present invention relates to the control of the humidification amount of the air conditioner humidifier using condensate, in particular, in response to the strong, medium, and weak operation according to the set air volume of the air conditioner humidifier for the air conditioner to actively discharge the strong, medium, weak humidification It relates to a humidification control circuit of.

In general, the low-temperature low-pressure liquid refrigerant introduced into the evaporator is heat from the surroundings of the evaporator in an air conditioner that cools the room by performing pressure, evaporation, and mechanical cooling, condensation, expansion, and evaporation. In this process, condensate is generated due to the condensation of moisture contained in the air on the surface of the evaporator. The condensate is continuously increased and inclined by the operation of the air conditioner. If you leave the surface of the evaporation plate and leave it as it is, it overflows to the outside and pollutes the room.

Thus, in order to prevent condensate accumulated in the evaporating plate from overflowing to the outside, a discharge hose is drawn out from the evaporating plate and discharged to the outside, or when installed in a low position such as a basement, a separate drip tray is provided to discharge the discharge hose. Treated condensate.

However, the condensate treatment apparatus as described above has a simple structure, but the condensate treatment is cumbersome, and the condensate discharged to the wall or floor of the building surrounding the equipment has a defect that pollutes the environment.

Thus, the present inventors vaporize the condensed water and discharge it to the outside, that is, the condensed water generated in the evaporator is purified by a filter, the bacteria contained in the purified water are removed by a heating means, and the sterilized purified water is removed from the vibrator. Developed a humidifier using condensed water in the air conditioner to be discharged to the outside by atomization and filed with the same person. However, in the above humidification device, a device in which the amount of humidification is appropriately adjusted according to the operating conditions of the air conditioner is insufficient, and countermeasures have been demanded.

The present invention has been devised to solve the above requirements, the purpose of the humidifier in response to the strong, medium, weak operation according to the set air volume of the air conditioner when the air conditioner is also actively strong, medium, weak humidification It is to provide a humidification amount control circuit of the humidifier for air conditioning by further increasing the efficiency of the humidifier.

Referring to the operation of the present invention configured as described above in detail based on Figure 4 as follows.

First, when the normal air conditioner operation is started by the start switch (S1) after the power is applied, the indoor air forcedly sucked into the evaporator 5 through the suction port by the operation of the indoor fan and the refrigerant cycle is heat-exchanged in the evaporator 5, and the discharge port is discharged. The cooling operation discharged to the room through (2) is performed (S2). In this cooling operation, strong, medium, and weak operation is automatically performed according to the room temperature conditions. The operation of setting the strong, medium, and weak conditions as an optimal condition for the subsequent humidification operation is set in advance (S3-S6). ).

On the other hand, in the cooling operation, the condensation water is generated in the evaporator 5 due to the condensation condensation of moisture contained in the air, and falls into the dish 6 along the inclined surface of the lower part of the evaporator 5.

In this way, when the condensed water is accumulated, foreign matters of the condensed water are primarily filtered through the filter 11 having a porous network installed in communication with the dish 6, and the filtered water is collected into the purified water container 7. The purified water is gradually collected and thus the water level is gradually increased due to the continuous cooling operation, and finally, when the water level rises to the full water level contact change position of the float switch (FS) (S7), the operation of the humidification device of the present invention proceeds (S7). ).

That is, the voltage Vcc connected to the pull-up resistor R1 flows to the ground side when the float switch FS is turned on, and the low level potential is input to the microcomputer 20, and the microcomputer 20 is connected to the output terminal PO1. The purified water collected in the purified water container 7 by opening the solenoid valve SV1 by turning on the relay RY1 with the low signal inverted by the inverter I1 by applying an open signal, that is, a high signal (S8). At the same time, the output terminal PO2 also applies the same high signal and turns on the heater HT with the low signal inverted by the inverter I2. Pull up to remove the bacteria contained in the purified water (S9).

The sterilized water through this operation is supplied to the humidification unit 9 through the inlet pipe, and the humidification unit 9 atomizes the water quickly by ultrasonic vibration of the vibrator operated by the control signal of the microcomputer 20, The gas is discharged to the outside through the discharge unit (10).

At this time, the condition set in step S3-S6 is checked, but when the weak condition S4 is set, the microcomputer 20 applies the high signal to the output terminal PO5 of the humidification control unit 24 to turn on the transistor Q3. The conduction is applied to the humidification circuit unit 25 by the voltage dropped by the resistors R5 and R6, so that the humidification is performed in a weak operation (S10).

If the above condition is set to medium (S6), the microcomputer 20 applies a high signal to the output terminal PO4 of the humidification control unit 24 to conduct the transistor Q2 to drop the voltage by the resistor R5. By being applied to the humidification circuit unit 25, the humidification is made by the middle operation (S10).

If the above conditions are set to steel (S5), the microcomputer 20 applies a high signal to the output terminal PO3 of the humidification control unit 25 to conduct the transistor Q1 so that the full voltage is immediately supplied to the humidification circuit unit 25. By being applied to, so that the humidification is made by strong driving (S10).

As described above, the present invention purifies the condensate generated in the evaporator by a filter, removes the bacteria contained in the purified water by the heating means, and sterilizes the sterilized purified water by the vibrator. As the condensate is discharged to the outside by generating it as a gas that is harmless to the human body and discharged to the outside, there is no need for a separate operation for removing condensate, and it has the advantage of fundamentally solving the contamination around the equipment caused by the condensate. By adding a device that actively humidifies the air conditioner to which the humidifier is added, a more efficient humidifying device can be realized.

The above description is only one embodiment of the present invention, and any change may be made within the scope of the present invention.
