Description

Dehumidifier and its control method {DEHUMIDIFIER AND CONTROL METHOD OF THE SAME}

The present invention relates to a dehumidifier and a control method thereof, and more particularly, to a dehumidifier and a control method thereof capable of selectively discharging hot and cold air.

In general, an air conditioner uses a method of extracting heat from ambient air by evaporating a refrigerant in an evaporator. As the refrigerant evaporates, the temperature of the evaporator is lowered and the temperature of the air passing through the evaporator is also lowered. Moisture contained in the surrounding air forms dew on the surface of the evaporator as the temperature drops.

As described above, the air passing through the evaporator is removed at the same time as the temperature decreases, which is the principle of the dehumidifier.

By the way, the conventional dehumidifier is the temperature of the air is removed while passing through the condenser 200 while the water is removed while passing through the evaporator (100).

This rise in temperature is a complaint of the dehumidifiers used in summer.

That is, the air that has passed through the condenser 200 has a problem in using a dehumidifier in summer because it acts as a hot air fan by raising the temperature of the surrounding air.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to enable the user to properly select the hot air and cold air discharge according to the season.

Dehumidifier according to the present invention to achieve the above object, the first evaporator is installed on the air intake side; A condenser installed in front of the first evaporator; A second evaporator installed at the front of the condenser and installed at a side through which air is discharged; A compressor for sucking the low temperature low pressure refrigerant from the first evaporator, compressing the low temperature low pressure refrigerant to high temperature and high pressure, and then discharging the refrigerant to the condenser; And a control valve installed in the flow path between the first and second evaporators and the condenser to control the flow direction of the refrigerant, and selectively controlling the hot and cold air through selective driving control of the second evaporator. Characterized in that configured to discharge.

In the control method of the dehumidifier according to the present invention, a cooling cycle in which the refrigerant alternately passes through the first and the second evaporator, the compressor, and the condenser, but the temperature of the indoor air discharged by adjusting the flow direction of the refrigerant is selectively selected. It characterized in that it comprises a step of controlling to.

During the control to discharge the warm air, the refrigerant is evaporated in the first evaporator to phase change to a low temperature low pressure; Compressing the refrigerant to a high temperature and high pressure in a compressor; And, after the refrigerant is transferred to the condenser to condense, comprising the step of evaporating again in the first evaporator, the air passing through the first evaporator is the temperature is lowered at the same time the water is removed, the first evaporator Air passing through the water is removed is characterized in that the temperature rises while passing through the condenser is discharged hot air relatively higher than the ambient air.

During the control to discharge the cold wind, the refrigerant is evaporated in the first evaporator to change phase to a low temperature low pressure; Compressing the refrigerant to a high temperature and high pressure in a compressor; And, after the refrigerant is transferred to a condenser and condensed, the refrigerant is evaporated in the second evaporator and evaporated again in the first evaporator, wherein the air passing through the first evaporator decreases in temperature at the same time. The water is removed, the air from which the water is removed by passing through the first evaporator increases in temperature while passing through the condenser, while the temperature is lowered while passing through the second evaporator, and the water is removed, so that the temperature is relatively higher than the ambient air. Low cold air is characterized in that the discharge.

According to the dehumidifier and the control method according to the present invention having the above-described configuration, by allowing the hot air and cold air to be selectively discharged, there is an effect that can increase the merchandise and improve the user's convenience.

2 is a schematic configuration diagram showing a dehumidifier according to the present invention.
3 is a schematic operation diagram showing a dehumidifier in which warm air is selectively discharged according to the present invention.
4 is a schematic operation diagram showing a dehumidifier in which cold air is selectively discharged according to the present invention.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 4.

As shown in FIG. 2, the dehumidifier according to the present invention includes a first evaporator 10a installed at a side where air is sucked in, a condenser 11 provided in front of the first evaporator 10a, and the condenser ( 11 is installed in front of the second evaporator (10b), the air is discharged to the side and the first and second evaporators (10a, 10b) and the condenser (11) to allow the air flow through A tank 13 to be generated and a water tank installed under the first and second evaporators 10a and 10b to store condensed water generated on the surfaces of the first and second evaporators 10a and 10b. 14, a compressor 12 which sucks a low temperature low pressure refrigerant from the first evaporator 10a, compresses the refrigerant to a high temperature and high pressure, and then discharges the refrigerant to the condenser 11, and the first and second evaporators 10a, 10b) and a control valve 15 installed in the flow path between the condenser 11 to control the flow direction of the refrigerant.

Dehumidifier according to the present invention is configured to further install the second evaporator (10b) to the air discharge side to the dehumidifier according to the prior art of FIG.

The dehumidifier configured as described above may selectively control the warm air and the cold air by a control switch not shown.

First, when controlling the control switch to discharge the warm air, as shown in Figure 3, the refrigerant is evaporated in the first evaporator (10a) phase changes to low temperature low pressure, is sucked into the compressor 12 to the high temperature After being compressed to high pressure, it is transferred to the condenser 11 to condense, and then performs a cooling cycle of evaporating again in the first evaporator 10a.

At the same time, the air in the room is sequentially passed through the first evaporator 10a, the condenser 11, and the second evaporator 10b by the rotation of the fan 13, where the second evaporator is used. 10b is in a stationary state and actually passes through the first evaporator 10a and the condenser 11.

Accordingly, the indoor air is first passed through the first evaporator (10a) of the dehumidifier, the temperature is lowered, and at the same time, the moisture contained in the dew drops in the first evaporator (10a), the condensate water is It is stored in the tank (14).

In addition, the air from which moisture is removed by passing through the first evaporator 10a may increase in temperature while passing through the condenser 11.

Therefore, in the dehumidifier according to the present invention, a warm air having a relatively higher temperature than the surrounding air is discharged through the discharge port (not shown).

On the other hand, when controlling the control switch to discharge the cold air, as shown in Figure 4, the refrigerant is evaporated in the first evaporator (10a) phase changes to low temperature low pressure, is sucked into the compressor 12 to the high temperature After being compressed to a high pressure, the condenser 11 is transported to condense and then evaporated in the second evaporator 10b, and performs a cooling cycle to evaporate again in the first evaporator 10a.

At the same time, the air in the room is sequentially passed through the first evaporator 10a, the condenser 11, and the second evaporator 10b by the rotation of the fan 13, where the second evaporator is used. Since 10b is in a driving state, two dehumidification operations are performed.

Accordingly, the indoor air is first passed through the first evaporator (10a) of the dehumidifier, the temperature is lowered, and at the same time, the moisture contained in the dew drops in the first evaporator (10a), the condensate water is It is stored in the tank (14).

Then, the air from which moisture is removed by passing through the first evaporator 10a is increased in temperature while passing through the condenser 11, and the temperature is lowered while passing through the second evaporator 10b.

At the same time, the moisture contained in the dew drops in the second evaporator 10b as the temperature decreases, and the condensed water is stored in the water tank 14.

Therefore, in the dehumidifier according to the present invention, cold air having a lower temperature than the surrounding air is discharged through the discharge port.
