The present invention relates to a buried parliment fan unit apparatus using indoor air.

A technical structure in which air suction means is installed on an indoor floor for blowing indoor air and discharging it to a window side to block outdoor air through a window is disclosed in Japanese Patent Laid-Open Publication No. 2000-337052, And the air passing through the window is discharged to the ceiling duct through the suction fan installed on the ceiling side to circulate the air. In addition, Korean Patent Registration No. 10-0488911 discloses a method of installing on a floor of a room, wherein a filter is installed in front of a blowing fan, a rectifying plate having a plurality of holes is provided on a discharge port side, and a suction fan is installed on the ceiling side These are shown in Table 1. However, since the method is still installed on the floor of the room, the use of the floor of the room is limited.

They are characterized in that a heat exchanging unit is provided to provide heat at the discharge site. In this method, a suction space for sucking indoor air and a heating space for heating are divided into two spaces by partition walls inside the housing, and a function for sucking and discharging indoor air is provided on the side of the upper surface, And the grill to be performed is respectively installed. However, this method is a method in which indoor air is heated and then discharged, so that it can be used in winter, but it is disadvantageous in that it can not be used in the summer when the air conditioner is used indoors and its use is limited. In addition, the rear of the grill in the width direction is a way of discharging the suction frontward, so that vortex due to mutual interference between suction and discharge air is generated in the front and rear of the grill, and the thermal efficiency is lowered.

In addition, a parimeter type fan unit has been developed as a domestic patent registration No. 10-077808 in a floor-embedded type in which a partition wall is placed in a housing to be buried beneath a floor of a room, a blowing fan is installed in one room, And a grill of a parimeter type for discharging the air and sucking and discharging the room air on the upper surface of the housing is known as shown in Table 3 below.

This has a problem in that the width of the housing is widened because the housing is divided into the air suction room and the air outlet room. Further, in the space of the same width, the front part sucks and the rear part exhausts, which causes a mutual vortex of the sucking and discharging air, resulting in a problem of lowering the discharging efficiency.

A convector, which is installed in a space between an indoor floor and a floor slab by a similar technique, is known as a domestic patent registration No. 10-0938389, which is installed on the floor of a room. The casing, which is called a housing, A second space B, a blowing fan in the first space, a heat exchange unit in the second space, and a filter disposed in front of the blowing fan. This is a method in which an inlet for introducing air in a space under the floor of a room is provided in front of the housing and a discharge port for discharging the floor air is blown to a discharge port formed on the floor surface by introducing the floor duct air, same. However, this is a method of sucking air in the indoor floor and the slab space, and thus has a structural problem in that it can not suck clean air.

2 is a sectional view taken along the line AA in Fig. 1,
3 is a plan view of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The front and rear bottoms of the blowing fan 120 of the inflow hole 110 are connected to the widthwise support 114, A first housing 100 which houses the blowing fan and whose upper surface is opened;

The first housing 100 has the same width as the first housing 100 and both sides of the first housing 100 in the longitudinal direction are connected to the suction spaces 131 and 132. The bottom surface of the first housing 100 is connected to the both suction spaces 131 and 132 A second housing (130) having a mixing space portion (134) And

And a grill unit 140 for covering the upper surface of the first housing 100 and the suction spaces 131 and 132 of the second housing 130 at the same time.

The longitudinal ends of the first housing 100 are closed by the side walls 115 and 116 and the upper end between the side walls 115 and 116 forms the central discharge grill 142 of the grill part 140.

The outer upper ends of the side walls 115 and 116 of the first housing 100 and the opposite side walls 135 and 136 of the second housing 130 form side suction grills 143 and 144.

The height of the side walls 135 and 136 of the second housing 130 is two or more times greater than the height of the side walls 115 and 116 of the first housing 100.

The present invention constructed as described above has the same principle as that of the conventional method of supplying indoor air to the window side in a parimeter manner. However, since the position where the room air is sucked is located on both sides in the longitudinal direction of the first housing 100 in which the blowing fan 120 is housed The width of the grill part 140 is reduced by half in comparison with the conventional method in which the suction is forwardly discharged to the front of the grill part so that the space occupied by the floor of the room is reduced and the utility of the indoor floor is increased.

The room air sucked from the side grill 143 and the side grill 144 shown in FIG. 3 flows through the side walls 135 and 136 of the first housing 130, the side walls 115 of the first housing 100, The air is sucked through the suction spaces 131 and 132 between the side supports 111 and 112 of the first housing 100 and the mixing space 134 below the inflow hole 110. [

In this case, since the height h1 of the side walls 135 and 136 is made two times higher than the height h2 of the side walls 115 and 116, the internal space of the mixing space portion 134 is relatively larger than the delivery amount, The flow of air slows down, so that the inflow of dust into the room air is reduced.

In addition, since the air discharged through the air blowing fan 120 is discharged in a small width as in the width direction pedestal 114 as shown in FIG. 1, the delivery speed is increased and supplied to the window, It cuts off heat and blocks cold air in winter, contributing to the increase of thermal efficiency of indoor air.

2, the flow of the inflow air through the side suction grille 143 and the suction space 131 is performed through the blowing fan 120 to the central discharge grill 142, but the blowing fan 120 And the side walls 115 and 116 have a space isolated from the discharge path so that the intake air to the side suction grills 143 and 144 and the suction air to the side suction grills 143 and 144 are separated from each other. Thereby enhancing air circulation efficiency by performing suction and discharge without mutual interference.

A first housing 111 and a second housing 131. The first housing 111 includes a first housing 111 and a second housing 114. The first housing 111 includes a first housing 111 and the second housing 111. The second housing 111 includes a first housing 114, A central discharge grille 143, 144, a side suction grille 143,
