Benefits of technology

[0016] It is another object of the present invention to provide a ventilator structure capable of minimizing the dimension of a ventilator by improving a structure of a total heat exchanger that performs heat exchanger by outdoor air and indoor air.
[0017] It is further another object of the present invention to provide a ventilator capable of decreasing a resistance in a flow path in such a manner that an airflow path is simplified, and a multiple layer flow section in a flow path is removed. In addition, a dead zone is not formed in the interior of a total heat exchanger in such that the air is uniformly flown in the entire flow paths in a horizontal direction of a total heat exchanger.
[0018] It is still further another object of the present invention to provide a ventilator capable of significantly enhancing a heat exchange efficiency of a total heat exchanger and capable of enhancing an efficiency in use of a space in such a manner that a ventilator is conveniently installed in a narrow installation space.
[0019] It is still further another object of the present invention to provide a ventilator in which a multiple layer flow section does not occur in a flow path, and a dead zone is not formed in a flow path, for thereby increasing a heat exchange efficiency of a total heat exchanger.

Problems solved by technology

However, in the instance where the indoor air is forcibly discharged using one blower, the additional cost is spent for warming or heating the indoor air to a desired temperature since the indoor warm air or hot air are directly discharged to the outside without passing through a certain filter.
However, since the total heat exchanger 20 is arranged in a diamond shape, the conventional ventilator has the following problems.
Therefore, it is impossible to make the cross section of the total heat exchange larger.

first embodiment

[0034]FIG. 3 is a schematic perspective view of a ventilator according to a first embodiment of the present invention.

[0035] As shown in FIG. 3, the ventilator 100 according to the present invention includes a casing 110 that forms an outer construction of the ventilator and protects inner elements, the suction air suction part 120 that is provided in one surface of the casing 110 and sucks outdoor air, and an air suction discharge part 121 that is provided in the other surface of the casing 110 so that air sucked through the suction air suction part 120 is discharged to the indoor. In addition, there are further provided an exhaust suction part 130 that is provided in one surface of the casing 110 and sucks indoor air, and an exhaust discharge part 131 that is provided in the other surface of the casing 110 so that the indoor air sucked through the exhaust suction part 130 is discharged to the outdoor. In addition, a total heat exchanger 200 is provided in a center portion of the ...

second embodiment

[0053]FIG. 7 is a plane view of a ventilator according to a second embodiment of the present invention. Since the second embodiment of the present invention is the same as the first embodiment of the present invention except for the construction of the duct, the detailed description will be omitted.

[0054] As shown in FIG. 7, the suction air discharge duct 123 and the exhaust suction duct 132 are crossed at a vertically distanced portion and are connected with the total heat exchanger 200. The suction air discharge duct 123 and the exhaust suction duct 132 are crossed in the interior of the ventilator 100 based on the characteristic of the fan. In the case that the suction fan 140 is a centrifugal fan like sirocco fan or turbo fan in which air is sucked in an axial direction and discharged in a radius direction, it is needed to minimize the resistance in air flow discharged from the suction fan 140. In other words, since the direction of the airflow in the centrifugal fan is curved ...

third embodiment

[0057]FIG. 8 is a plane view of a ventilator according to a third embodiment of the present invention. The third embodiment of the present invention is the same as the second embodiment of the present invention except for the construction of a switching unit provided in the flow path. Therefore, the detailed description will be omitted except for the above different construction.

[0058] In the third embodiment of the present invention, the ventilator 100 further includes a ventilation duct 170 connected with the exhaust suction part 130 and the exhaust discharge part 131. In addition, a flow path switching unit 160 is further provided at an entrance of the exhaust suction part 130. In particular, the flow path switching unit is preferably provided near the exhaust suction part 130. If it is installed near the exhaust fan 150, the installation may be complicated. In addition, a certain problem may occur in the operation of the flow path switching unit 160 due to a turbulent flow near...

Abstract

The present invention relates to a ventilator. Channels are horizontally extended in the interior of a total heat exchanger. The channels are vertically stacked for thereby enhancing the efficiency of heat exchange.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a ventilator, and in particular to an improved ventilator that allows to form a smaller heat exchanger by enhancing a heat exchange efficiency of supplied air and exhausted air in a heat exchanger in which the heat exchange is performed by making the supplied air and exhausted air to crossed each other. [0003] 2. Description of the Background Art [0004] Generally, in a certain limited space in which air is not well circulated, and various kinds of lives breath together, the amount of oxygen gradually decreases while the carbon dioxide gradually increases. When a person stays in a limited narrow space or a space with many persons therein, it is needed to regularly change the indoor air with external fresh air. In this case, a ventilator is generally used. [0005] The conventional ventilator adapts a method of forcibly discharging indoor air to the outside using one blower. However, in ...
