Description

[0001] Airconditioner with bypass apparatus [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a variable bypass ventilation air circulator, and more particularly, It is possible to easily control the flow of air by forming a damper and an exhaust direction adjusting member inside the bypass means, and particularly to an air circulator capable of quickly discharging smoke and toxic gas generated in a fire and terrorism from the room .

In general, recently built buildings are putting much effort into insulation to save energy and paying much attention to ventilation for health.

Therefore, in order to satisfy both insulation and ventilation, indoor air and outside air are forcibly sucked and discharged through a ventilating fan, and a ventilation device (ventilating device) for buildings, which enables air purification and energy saving by using a filter or heat exchanger The above-mentioned building air circulator is installed on the ceiling for efficient utilization of the space and sucks and discharges indoor air and outdoor air through a duct. The air circulator may be provided with cooling (air conditioning) and heating (hot air) functions.

In the conventional air circulator, since the air is sucked and discharged through the heat exchange element built in the middle part of the case, energy can be saved, but the air flow is interrupted by the heat exchanger. Therefore, when indoor air is severely contaminated and needs to be discharged promptly, it is possible to quickly discharge indoor air without using a heat exchanger by using a separate bypass means.

1, an air circulator having a conventional bypass means includes a case 2 having a hollow formed therein, an exhaust port 3 formed at one end of the case 2, and an outside air inlet port 4 An air intake port 5 and an ambient air supply mechanism 6 formed at the other end thereof and an electric heat exchange member 7 inserted in a direction across the hollow of the case 2; First and second diaphragms 2a and 2b which are extended to the left and right sides of the case 2 to divide the hollow of the case 2 into upper and lower portions, an air supply fan 8 for sending the introduced outdoor air to the room, (10) for bypassing room air introduced into the outside air supply mechanism (6) and directly exhausting the air to the exhaust fan (9), and an exhaust fan ; A cylindrical mesh section 21 provided between the air intake port 4 and the total heat-exchanging member 7 and coated with a metal hydrate catalyst 211, and an ultraviolet lamp 20 installed in the longitudinal direction of the mesh section 21, (20) composed of a transparent polypropylene copolymer protective film (23) formed in a cylindrical shape so as to surround and protect the ultraviolet lamp (22); An outdoor temperature sensor 31 and an indoor temperature sensor 32 installed in the case 2 for measuring the temperature, installed in the indoor and outdoor units of the bypass means 10, the air purifying means 20, And a control unit 30 connected to the carbon dioxide sensor 33 for measuring the amount of carbon dioxide in the indoor space and controlling the air conditioner according to the set condition. The ventilation unit is provided with a bypass means and an air purifying means, as disclosed in Japanese Patent Laid-Open No. 10-0675771 .

However, the conventional air circulator has the bypass means 10, which bypasses the room air introduced into the outside air supply mechanism 6 and is directly discharged to the exhaust fan 9, is formed integrally with the case inside the case 2, A bypass means passage 13 is formed at one side of the case 2 so as to allow upper and lower spaces to pass therethrough and a third diaphragm (not shown) bent at a predetermined angle inside the case 2, The first bypass means 11 and the second bypass means 12 are formed in the third diaphragm 14 so as to communicate with the bypass means passage 13, The structure is complicated due to the characteristics of the case formed by molding, and it is disadvantageous in that it is very difficult to manufacture and assemble.

In addition, it is disadvantageous in that smoke and toxic gas generated in the case of fire and terrorism can not be quickly discharged from the room.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The variable bypass ventilation air circulation unit according to the embodiment of the present invention includes a case 1100 having a heat exchange element built-in space 1100e in which a heat exchange element E is embedded, B having an exhaust air intake space A formed at the other end thereof and an exhaust air intake space portion 1100b having an exhaust air intake space C having an air intake air space A And an air supply fan housing space 1100d having an air supply fan housing 1100a and an outside air supply mechanism D. The air circulator includes an exhaust fan housing space 1100b and an outside air intake space 1100c, The upper air inlet space 1100a and the upper part of the air supply fan built-in space 1100d are opened to form a vent hole 1110. Each of the vent holes 1110 is connected to a cross- (1300), and the connection pipe (1300) is connected to the inside of the connection pipe (1300) by a vent pipe (1200) At least one exhaust direction adjusting member 1330 driven by a motor 1340 is provided to change the direction of the air passing through the connection pipe 1300 or to control the flow and the like.

The exhaust direction regulating member 1330 is installed at a central portion of the connecting pipe 1300 that intersects with each other, so that one side of the connecting pipe is closed and the other side is opened, or both the one side and the other side are closed or opened, The direction of air supply and exhaust can be freely adjusted.

The exhaust direction regulating member 1330 includes a blocking plate for blocking the flow of air and a motor 1340 for rotating the blocking plate. At this time, the shaft of the motor is coupled to the shaft hole 1331 formed at the lower end, the upper end, the side surface, or the like of the blocking plate so that the rotating plate can be rotated by driving the motor to change the direction of the air.

Of course, in order to change the direction of the air at this time, it is natural that it is controlled by the organic operation of the exhaust direction regulating member 1330 and the dampers of the respective vent pipes 1200.

The exhaust direction regulating member 1330 may be installed at one side of the air flow guide member 1310 formed at the center of the connection pipe 1300 to guide the flow of air.

In the present invention, the vent pipe 1200 has a flange 1211 which is coupled to the case 1100 by a fastener or a joining means (not shown) at a lower end thereof. A damper 1250 driven by a motor 1240 is supported by a shaft 1251 on the inner side of the exhaust pipe 1220. The damper 1250 is supported by a shaft 1251, It is built to be rotatable. At this time, the flange 1211 preferably has a structure in which a screw hole 1211a for fastening the fastener is perforated.

A motor housing 1230 having a motor fixing hole 1231 is formed on one side of the exhaust pipe 1220 and a motor fixing hole 1231 is formed on the outside of the through hole. The motor 1240 is exposed to the inside of the motor 1220 and coupled to the shaft 1251 of the damper 1250 so that the motor 1240 is fixed to the motor fixture 1231 by a fastener (not shown).

As described above, the damper 1250 may be formed in each of the vent pipes 1200 so that the air discharged through the damper 1250 is not mixed with the air supplied from the damper 1250, Direction and so on.

That is, when exhausted air passes through the connection pipe 1300, the damper of the vent pipe connected to the outside air suction space part 1100c and the air supply fan built-in space part 1100d is closed to block the inflow into the room, When the air passing through the connecting pipe 1300 is closed, the damper of the vent pipe connected to the inside air suction space part 1100a and the exhaust fan built-in space part 1100b may be closed to prevent the exhaust air from being discharged outdoors.

In the present invention, when smoke or toxic gas is filled in a room due to an emergency such as a fire or a terrorist attack, the air supply pipe connected to the air supply pipe for supplying air outside the room is also discharged. Of course, at this time the exhaust fan is configured to rotate at full speed. Also, in this case, the pipes used as conventional class engines and exhaust pipes are all dedicated to the exhaust pipe for removing smoke or toxic gases. Therefore, unlike the conventional air circulator, the present invention can very quickly remove smoke and toxic gases.

Further, the present invention can more smoothly control the flow of air by the following structure.

That is, an air flow guide member 1310 is formed at the center of the connection pipe 1300, and the air flow guide member 1310 includes a horizontal plate 1310a and upper portions extending from both sides of the horizontal plate 1310a The upper shielding plate 1310b and the lower shielding plate 1310b are formed by cutting off the center of the connecting pipe 1300 with a pair of upper shielding plates 1310b and a pair of lower shielding plates 1310c extending downward from the other side of the horizontal plate. May not be formed.

At this time, the air flow guide member 1310 branches the air exhausted by the upper shielding plate 1310b and the lower shielding plate 1310c and air supplied by the horizontal plate 1310a, So that air to be supplied from the air supply pipe 1300 can not be mixed in the connection pipe 1300.

The air flow guide member 1310 may be integrally formed with the connection pipe 1300 in the connection pipe 1300. However, for convenience of manufacture, the air flow guide member 1310 may not be leaked by the fixing member 1320, It may be fixed.

In addition, a filter 1260 may be installed on one side of the connection pipe 1300 to remove foreign substances in the air passing through the connection pipe 1300.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
