The first four-way valve 350A has two suction ports formed on one side and two discharge ports formed on the other side so as to communicate with an internal space in which the diaphragm 353 is built, and one side of the diaphragm 353 is connected to two suction ports So that it can be rotated. Accordingly, when the other end of the diaphragm 353 is positioned between the two outlets as in the first four-way diverter 350A shown in Figs. 4A and 4B, two inlets and two outlets are communicated one to one, (The direction in which the two outlets are in the same direction when viewed from the other end of the partition plate), as in the case of the first four-way countermeasures 350A shown in Figs. One suction port is branched and communicated to the two outlets.

The first four-way valve 350A configured as described above connects any one of the two suction ports to the indoor suction holes 311 and connects the other to the outdoor suction holes 312, One-to-one connection is made to the two intake ports of the deflection 350B. Accordingly, the two intake ports of the second four-way diverter 350B adjust the rotational position of the diaphragm 353 of the first four diverging sides 350A to supply the indoor air to any one of the intake ports, Is supplied to the other air intake port, and only the situation in which only the indoor air is supplied in common, and only the outdoor air is supplied in common.

The second four-way counterpart 350B can divide the cylindrical inner space into two spaces of approximately semicircular shape with a partition wall 354 rotatable about a rotation axis, and a hole in four directions radially forming an angle of 90 degrees Two holes facing each other are used as an air inlet and the other two mutually opposed holes are used as an air outlet. The two air inlets are connected to the two air outlets of the first four-way outlets 350A on a one-to-one basis, and the two air outlets are connected to the first space 341 and the second space 342 of the air- . Thus, by changing the rotation angle of the partition wall by 90 degrees, the connection between the intake port and the exhaust port can be changed like a four-way switching knob.

The air control valve 350 configured as described above determines whether the intake air is to be the indoor air or the outdoor air or the first four-way countermeasure 350A, and the indoor-side air and the outdoor- The exhaust direction toward the indoor side and the outdoor side is defined as the second four-way side 350B.

The first four-way counterbalance 350A and the second four-way counterbalance 350B include step motors 351 and 352 controlled by a controller 550 of a power supply unit 500 And the partition walls 353 and 354 are rotated by the stepping motors 351 and 352, respectively. If the user manually manipulates the stem motor in place of the stem motor, for example, the rotation axis of the partition wall is extended and protruded to the outside of the case part 200 to make a handle.

According to the embodiment of the present invention, the air control valve 350 may include the first four-way valve 350A and the second four-way valve 350B to perform the first, second, third, The present invention is not limited to this, and other types of valve combinations are also possible.

The flow of air formed in accordance with the opening and closing states of the respective valves in the air control valve 350 'shown in FIG. 6 can be understood by those skilled in the art, so detailed description thereof will be omitted.

The cooling / heating unit 340 may be built in the casing unit 200 by miniaturizing a conventional cooling / heating unit (for example, a heat pump) that forms a low-temperature zone and a high-temperature zone using the heat of the refrigerant or the condensation heat. 4 and 5, the thermoelectric device 343 is constructed using a thermoelectric device 343 that is simple in structure and compact in size.

The cooling and heating unit 340 forms a first space 341 and a second space 342 by dividing the internal space of the body in which the internal space is formed by the thermoelectric elements 343 and the first space 341 and the second space 342, The space 342 is configured to allow the air supplied from the air control side 340 to pass through and to be exhausted to the exhaust hole 322.

The thermoelectric element 343 absorbs heat on one side by the Peltier effect and generates heat on the other side to generate a temperature difference between both sides. When the polarity of the DC current is changed, the heat absorbing surface and the heat generating surface are changed. Therefore, the thermoelectric element 343 absorbs heat (cooling) in one space and the other space generates heat in the first space 341 contacting the one surface and the second space 342 contacting the other surface depending on the polarity of the DC current . That is, the heat absorbing space and the heat generating space are changed according to the polarity of the direct current supplied from the power supply means 500 described below.

If the temperature of the first space 341 is lower than the temperature of the second space 342, the air having passed through the first space 341 is exhausted to the indoor side to cool the room, and the temperature of the first space 341 When the temperature of the second space 342 is higher than the temperature of the second space 342, the air that has passed through the first space 341 is exhausted to the room side to heat the room.

The air passing continuously through the second space 342 is heat-exchanged and exhausted to the outdoor side, so that the indoor air-cooling and heating by the thermoelectric element 343 can be stably performed. That is, when heat is absorbed in the first space 341 and the second space 342 is heated to cool the room, the heat of the second space 342 must be released. The second space 342 must be heated when the first space 341 is heated and the second space 342 absorbs heat to heat the room. Is heated by the heat of the intake air.

4 and 5, in order to increase the heat exchange efficiency between air in the first space and the second space that absorb heat and generate heat by the thermoelectric element 343, A thermally conductive plate having protruded heat exchange fins 344 and 345 is attached to both surfaces of the thermoelectric element 343, respectively.

The fans 330 for intake and exhaust are installed on the exhaust side of the first space 341 and the exhaust side of the second space 342, respectively, to pump air toward the arrangement holes.

2 and 3, the indoor side exhaust hole 321 is formed on the bottom surface of the case part 200 and exhausts downward. The exhaust hole 321 has an enlarged tube shape having a wider width toward the lower side, So that the heat of the air discharged to the indoor side is transmitted to the flange portion 100. [ To this end, the upper end of the flange 100 is fixed on the bottom surface of the case part 200, or the upper surface of the indoor side exhaust hole 321). Accordingly, when the room temperature is lowered, the temperature of the beep portion 100 is lowered to lower the radiant heat of the beep portion 100 delivered to the room, and the temperature of the beep portion 100 is increased during the indoor heating, 100).

It is preferable that the indoor air suction holes 311 are formed on the front surface of the case part 200. The indoor air suction holes 311 are formed on the bottom surface of the case part 200. [

In addition, the present invention generates indoor electricity by receiving sunlight incident through a window, thereby cooling and heating the room, thereby making the room more comfortable. Particularly, even if the heat of the curtain, which is heated by the heat received through the window in the summer, flows into the room through the radiant heat, the radiant heat flowing into the room can be lowered by lowering the temperature of the curtain. On the other hand, in winter, the temperature of the curtain can be increased to block the curtains.

In addition, according to the present invention, as shown in Table 1 and Figs. 4 and 5, the operation can be selected with four kinds of air flows. In the case of the second operation, the room can be ventilated while cooling and heating.

The third operation and the fourth operation can be suitably used according to the temperature difference between the room and the outside.

For example, if the indoor temperature is higher than the outdoor temperature in the early stage of starting the indoor air conditioning in the summer, the outdoor air is sucked, cooled in the first space and exhausted to the room, Is high in efficiency, the fourth operation is performed. When the room temperature is lower than the outdoor temperature as the cooling is continued, the first operation or the second operation is performed. In the fourth operation, the process of switching to the first operation or the second operation may be performed automatically.

That is, a temperature sensor 540 that senses a room temperature and an outdoor temperature may be provided to allow the user to select the first operation or the second operation by operating the operation unit 530 and to control the cooling / heating unit 300 When the indoor temperature is higher than the outdoor temperature as a result of sensing by the temperature sensor 540 at the time of operation, the fourth operation is automatically performed and the indoor temperature and the outdoor temperature are continuously measured by the temperature sensor 540. When the indoor temperature becomes lower than the outdoor temperature, the operation is switched to the first operation operated by the user or the second operation operated by the user.

If the outdoor temperature is higher than the room temperature as a result of sensing by the temperature sensor when the user operates to perform the first operation or the second operation, the outdoor operation is switched to the fourth operation to branch the outdoor air to the first space and the second space And exhausts them to indoor and outdoor. When the room temperature becomes higher than the outdoor temperature in accordance with the indoor heating, the operation is switched to the first operation operated by the user or the second operation operated by the user. 1, the temperature sensor 540 is installed at the end of the indoor air intake hole 311 and at the end of the pipe 312a connected to the outdoor air intake hole 312, . &Lt; / RTI >

As another example, when it is necessary to cool the room and to discharge the room-side air to the outdoor side in a situation where the room temperature is lower than the outdoor temperature, the air conditioner 350 is operated as the third operation. That is, since indoor air is cooled to the first space and indoor air is discharged while exhausting the indoor air through the second space, the heat of the second space is discharged to the indoor air having a lower temperature than the outdoor, It is possible to discharge the heat more efficiently than to discharge the heat in the second space by using the outdoor side air having a higher temperature.

As described above, in the third operation and the fourth operation, air is allowed to flow because the room is not a completely enclosed space even if only one of the indoor and the outdoor air is sucked and exhausted to the indoor side and the outdoor side after heat exchange. Of course, when the third operation or the fourth operation is performed, it is also possible to provide a separate piping for communicating between the room and the outside.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, . &Lt; / RTI > Accordingly, such modifications are deemed to be within the scope of the present invention, and the scope of the present invention should be determined by the following claims.
