However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in Figs. 3 and 4, the window integral machine ventilator constituting the control system according to the present invention includes a window frame 100. Fig.

The window frame 100 is a window frame that is fixed to an opened portion of the window frame 100. The window frame 100 is configured to be slidable with the window frame 200 inserted therein. So that the outside can be seen.

At this time, a ventilation housing 300 is installed on one side of the upper surface of the window frame 100. The ventilation housing 300 is provided with an indoor exhaust duct 310 which is connected to the indoor side through the window frame 100, The duct 320 is connected.

Accordingly, the air contaminated in the room is introduced into the ventilation housing 300 through the indoor exhaust duct 310 and then passed through the communicating indoor air outlet 312 to the outdoor air outlet 342 formed at one side of the lower surface of the ventilation housing 300 And the outdoor fresh air is sucked into the ventilation housing 300 through the other side of the lower surface of the ventilation housing 300 and then is filtered and exchanged with heat and then communicated with the indoor air supply duct 322 through the indoor air supply unit 322 320 to the room.

5 to 7, the ventilation housing 300 includes a heat exchange module 302 and a module case 304. The heat exchange module 302 is detachable from the module case 304, .

The heat exchange module 302 is formed in a rectangular box shape with one side opened, and the inside is partitioned into independent spaces by partition walls 330. Inside the partitioned spaces, the first plate type heat exchanger EX1 and the second plate type heat exchanger The two-plate heat exchanger EX2 is arranged adjacent to the heat exchanger 2 in succession and is sealed by the module cover (MCV) after the built-in article is mounted.

At this time, the flow paths in which the first and second plate heat exchangers EX1 and EX2 are disposed are designed to communicate with each other so that heat exchange is possible.

Here, the first and second plate heat exchangers EX1 and EX2 are known indirect heat exchangers, in which the flow of air flowing through the plate is not overlapped with each other, that is, It is a heat exchanger to make it happen, and it is various.

Therefore, the shape of the plate-like heat exchanger in the present invention is not particularly limited, but it is preferable that the plate-like heat exchanger is arranged in a diamond shape as shown in the figure.

An exhaust fan (340) and an air supply fan (350) are installed on one side of the second plate heat exchanger (EX2) while being separated from each other.

6, an outdoor outlet 342 is formed on a lower surface of the heat exchange module 302 at a position directly below the exhaust fan 340, and a heat exchange module 302, which is opposite to the outdoor outlet 342, An outdoor air inlet 352 is formed.

A filter groove 360 is formed at the side of the first plate heat exchanger EX1 so as to communicate with the outdoor air inlet 352 to flow the outside air to the first plate heat exchanger EX1, A filter housing 362 is detachably mounted in the groove 360 and a cartridge 364 having a filter F built therein is replaceably inserted into the filter housing 362.

Accordingly, when the air supply fan 340 and the air intake fan 350 are operated, the indoor air is introduced into the heat exchange module 302 through the indoor exhaust port 312 and then flows into the upper side of the first plate heat exchanger EX1 Is then discharged to the lower side of the first plate heat exchanger EX1 and then flows into the lower side of the second plate heat exchanger EX2 and then discharged to the upper side of the second plate heat exchanger EX2, 340 to the outside of the room through the outdoor outlet 342.

Since the exhaust fan 340 is installed close to the second plate type heat exchanger EX2, the fan exhaust duct DDT is short as shown in FIG.

On the other hand, the fresh fresh air sucked into the outdoor air inlet 352 flows into the filter groove 36, is filtered through the filter F, flows into the lower side of the first plate heat exchanger EX1, Is discharged to the upper side of the heat exchanger EX1 and then to the upper side of the second plate type heat exchanger EX2 and then to the lower side of the second plate type heat exchanger EX2, The air is sucked into the air supply fan 350 through the long fan supply duct SDT and then supplied to the room through the indoor air supply mechanism 322.

At this time, the indoor exhaust air whose temperature has risen in the first and second plate heat exchangers EX1 and EX2 and the outdoor air supply air whose temperature is relatively low do not meet with each other but heat exchange is performed to the boundary of the plate, It is possible to supply the room with the temperature of the fresh air supply being raised to some extent, thereby preventing the room temperature from dropping, which is very efficient because the heating cost can be reduced accordingly.

Here, the above-described control is performed by the ventilation controller CTR (see Fig. 3), and the ventilation controller CTR is a kind of microcomputer. The ventilation controller CTR may be installed on the outer surface of the ventilation housing 300 or may be embedded therein.

Meanwhile, the filter F may be a pre-filter, a medium filter, a wave filter, or a filter effective for blocking yellow dust or fine dust.

More preferably, the filter F may be a triple filter consisting of a pre-filter-medium filter-HEPA filter.

Since the ventilation housing 300 is installed at a height higher than that of the human key, the ventilation housing 300 is directly lowered when the fixing member of the heat exchange module 302 is loosened There is a risk of injury.

Therefore, in the present invention, a multi-step engagement structure is provided to enable safe separation.

7, the 'A' shaped hooks 370 are rotatably hinged on both sides of the heat exchange module 302, and the vertically bent portions of the hooks 370 A hook 372 protrudes from the side surface, and an elastic piece 374 is formed on the inner surface of the bent portion.

In this state, the module case 304 is fitted into both grooves (not shown) of the module case 304, and the groove is formed with a hook to which the hook 372 can be hooked.

Therefore, since the hook 370 is extended outwardly by the elastic force of the elastic piece 374, the hook 372 is hooked on the jaw, so that the heat exchange module 302 is engaged with the module case 304 do.

Therefore, when the fixing member is loosened to separate the heat exchange module 302, the heat exchanging module 302 that has been pushed up is lowered, and the hook 372 is hooked on the jaw,

Accordingly, the user can escape the risk of a safety accident such as an accident because the heat exchange module 302 does not fall off. When the user desires to separate the heat exchanging module 302, the user can easily release the hook 372 by pressing the hooking hole 370 with both hands, can do.

The filter housing 362 can be detachably detachable by the same principle so that the filter housing 362 can be easily replaced by the user.

That is, as shown in the example of FIG. 6, the upper end of the filter housing 362 has a one-touch latch structure, that is, a one-touch latch structure in which the latch structure is once clicked, A filter elastic piece 362a is cut on the side surface and a filter hook 362b is protruded on a part of the filter elastic piece 362a and a hook jaw 362b is formed on a surface of the filter groove 360 corresponding to the filter elastic piece 362a T) is formed and is displayed on a fixed distance display by the one-touch type latch, it is lowered by a certain distance and hooked on the hook tongue T. When the user pushes the filter elastic piece 362a, .

In this case, it is needless to say that it is possible to constitute a simple fitting type without the one-touch type latch structure and a latching structure using the hook tongue T. FIG. In this case, however, a means such as a cap for sealing the lower end of the filter groove 360 may be further required.

As described above, the integrated window type machine ventilator according to the present invention uses two plate type heat exchangers to efficiently perform the ventilating action, thereby reducing the cooling and heating costs and making the air curtain through the glass (G) Can be obtained.

Particularly, in the present invention, a control system capable of controlling IoT by incorporating the above-described window integral mechanical ventilation system is constructed.

8, a wireless communication module (not shown) capable of wireless communication via WiFi or a beacon is mounted on the ventilation controller (CTR), and the wireless communication module is installed in the home And is configured to be capable of wireless communication with an Access Point (AP)

Therefore, a control signal through the AP 500 can be automatically controlled by transmitting the control signal from the outside via a wireless terminal, such as a smart phone.

In particular, the present invention further includes a sensor box 400 at an arbitrary position in a room, and the sensor box 400 is configured to transmit a detection signal to the AP 500, Humidity, fine dust, carbon dioxide concentration, TVOC, etc., can be detected at the same time, so that it can be utilized.

The AP 500 is configured to communicate with the management server 600 to transmit and receive a control signal. The management server 600 may be provided in a nationwide unit management company, or may be provided in a management office.

In addition, connection to the management server 600 can be performed through a wired / wireless terminal such as a permitted PC, tablet, or smart phone.

At this time, the management server 600 may communicate with the meteorological office server 700 to receive weather information and inform the user of the weather information.

Then, the user can adjust the indoor air quality by ventilating before entering the house by referring to today's weather and the like.

Of course, the detection information detected by the sensor box 400 is also displayed on the wireless terminal, so that the user can broaden various control choices.
