It is preferable that the finished air can be introduced.

Hereinafter will be described the operation of the multifunctional drying apparatus according to an embodiment of the present invention including the above-described configuration.

First, the case where both the 1st space 3 and the 2nd space 5 supplies hot air is demonstrated.

When the user inputs a drying target in each space, the hot air supply unit 7 is operated.

Air discharged from the first space is introduced into the hot air supply unit 7 through the first inflow passage 711. At this time, the first inflow valve 715 provided in the first inflow passage 711 should be open.

In addition, the air discharged from the second space 5 is introduced into the hot air supply unit 7 through the second inflow passage 717, and in this case, the second inflow valve 717 also needs to be open like the first inflow valve. do.

Air introduced into the hot air supply unit 7 through the inflow passage in the first space 3 and the second space 5 is introduced into the heat exchange passage 73 and dehumidified in the evaporator 731.

The dehumidified air is heated by heat exchange in the first condenser 733, and some of the heated air flows into the second space 5 through the second outflow path 753 to dry the drying object in the second space. Done.

At this time, the second valve 7531 provided in the second outflow passage should be open.

Meanwhile, some of the air heated by heat exchange in the first condenser 733 is introduced into the second outflow passage 753 as described above, but the other part is heated once more while passing through the second condenser 734.

Therefore, the air can be heated to a higher temperature than the air supplied to the second space 5 through the second outflow passage.

Since the air that has completed heat exchange in the second condenser 734 must be supplied to the first space 3 through the first outflow passage 751, the first valve 7511 provided in the first outflow passage is in an open state in this case. Should be.

Therefore, through the above-described process, the drying targets provided in each space can be dried at the same time.

Hereinafter, the case where hot air is supplied only to the first space will be described.

In order to supply hot air only to the first space 3, the second inflow valve 717 closes the second inflow passage 713.

After the second inlet valve 717 closes the second inlet passage 713, the first inlet valve 715 of the first inlet passage 711 is opened so that the air in the first space 3 is supplied to the hot air supply unit ( 7) to be introduced into the heat exchange passage (73).

The air introduced into the heat exchange path 73 is dehumidified and double heated while passing through the evaporator 731, the first condenser 733, and the second condenser 734.

Dehumidified and heated air is supplied to the first space 3 through the first outflow passage 751, in which case the first valve 7511 is open.

On the other hand, in order to supply hot air only to the first space 3, it is preferable that the second valve 7531 is maintained in a state in which the second outflow passage 753 is closed, and both the first and second condensers are used. Therefore, the refrigerant valve L41 must be controlled to open the refrigerant pipe L2 and the bypass refrigerant pipe L4 is closed.

Hereinafter, the case where hot air is supplied only to the second space will be described.

In this case, the first inflow valve 715 should close the first inflow passage 711, and the second inflow valve 717 should open the second inflow passage 713.

In addition, the refrigerant valve L41 must be in a state in which the bypass refrigerant pipe L4 is opened and the refrigerant pipe L2 connected to the refrigerant valve L41 and the second condenser 734 is closed. Accordingly, the refrigerant circulates through the evaporator 731, the compressor 732, the first condenser 733, and the expander 735.

In addition, the first outflow passage 751 should be closed by the first valve 7511, but the second outflow passage 753 should be open by the second valve 7531.

Therefore, the air discharged from the second space 5 flows into the heat exchange passage 73 of the hot air supply unit 7 to be dehumidified in the evaporator 731, and the dehumidified air exchanges heat only in the first condenser 733. After being heated, it can be supplied to only the second space 5 through the second outflow channel 753.

Hereinafter, another embodiment of the present invention multifunctional drying apparatus will be described with reference to FIG. 2.

This embodiment is a case where the hot air can be selectively supplied to the first space or the second space.

The multifunctional drying apparatus 100 ′ according to the present embodiment includes a housing 1, a first space 3, a second space 5, and a hot air supply unit 7.

Meanwhile, the hot air supply unit 7 includes an inflow passage 71, a heat exchange passage 73, and an outlet passage 75, but the heat exchange passage 73 is the same as the configuration disclosed in the embodiment of FIG. 1. Is omitted.

The inflow passage 71 includes a first inflow passage 711 and a second inflow passage 713. However, it is distinguished from the embodiment disclosed in FIG. 1 in that the inflow passage 71 is the first inflow passage 711 and the second inflow passage 713 are combined at one point to exchange heat through one inflow passage 71 It is in communication with the flow path (73).

On the other hand, it is preferable to further include an inlet valve 719 that can selectively open each flow path at the point where the first inflow passage 711 and the second inflow passage 713 are combined.

It is preferable to further include a supply valve 755 that can selectively open the respective flow paths at branch points of the first outflow channel 751 and the second outflow channel 753.

Hereinafter, the operation of the multifunctional drying apparatus 100 ′ including the above-described configuration will be described.

Referring to the case of supplying hot air to the first space 3, the controller (not shown) allows the inlet valve 719 to open the first inlet passage 711 and close the second inlet passage 713. .

In addition, the control unit (not shown), the refrigerant valve L41 closes the bypass refrigerant pipe L4 and opens the refrigerant pipe L2 so that the refrigerant evaporates 731, the compressor 732, the first condenser 733, and the first refrigerant. It must be controlled to circulate the two condenser 734 and the expander 735.

Further, the controller (not shown) should control the second valve 755 to open the first outflow channel 751 and close the second outflow channel 753.

Therefore, the air introduced from the first space 3 is dehumidified in the evaporator 731, firstly heated in the first condenser, and further heated in the second condenser, and then circulated to the first space through the first outflow passage. The drying object is dried.

When the hot air is supplied to the second space 5, the controller (not shown) controls the inlet valve 719 to close the first inflow passage 711 and open the second inflow passage 713.

In addition, the controller (not shown), the refrigerant valve L41 opens the bypass refrigerant pipe L4 and closes the refrigerant pipe L2 connecting the refrigerant valve L41 and the second condenser 734 so that the refrigerant evaporates. ), The compressor 732, the first condenser 733 and the expander 735 should be controlled to circulate.

Further, the control unit (not shown) should control the second valve 755 to close the first outflow passage 751 and open the second outflow passage 753.

Therefore, the air introduced from the second space 5 is dehumidified in the evaporator 731 and is first heated in the first condenser 733 and then passed through the second condenser 734, but in the second condenser 734, heat exchange is performed. Since this does not occur, the air heated in the first condenser 733 is supplied to the second space 5 through the second outflow channel 753 as it is.

As a result, since the air supplied to the second space 5 cannot be heat exchanged once more in the second condenser 734, the air supplied to the second space 5 has a lower temperature than the air supplied to the first space 3. The hot air of different temperatures can be selectively supplied to the first space and the second space.

The present invention may be practiced in various forms and is not limited to the above-described embodiment. Therefore, if the modified embodiment includes the components of the claims of the present invention should be regarded as belonging to the scope of the present invention.
