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

The first embodiment of the present invention proposes an apparatus for managing indoor air by a heat recovery system. Heat recovery can be applied to any type of waste heat absorbing method. But is not necessarily limited to, indoor air management for small houses.

According to the present invention, the housing (20) forms a flow path of air to the intake pipe (21) and the air supply pipe (22). The housing 20 is a housing for housing a dust collecting means 30 and a purifying means 40 which will be described later. The housing 20 sucks outside air by the intake pipe 21 and supplies clean air, . The air supply pipe 22 of the housing 20 communicates with the OA pipe 11 of the heat recovery unit 10 to be described later.

Meanwhile, the housing 20 may be detachably coupled to the heat recovery device 10 via a hook 28. [ The heat recovery apparatus 10 has a structure in which an OA pipe 11, an SA pipe 12, an RA pipe 13, and an EA pipe 14 are arranged around a sensible heat exchanger 16. The OA pipe 11 flows into the outdoor air and the SA pipe 12 supplies the outside air to the room and the RA pipe 13 flows into the indoor return air, The EA pipe 14 exhausts the recovered air to the outside (atmosphere). 1 illustrates a structure in which the housing 20 is attached to and detached from the bottom of the heat recovery apparatus 10 with a hook 28. As shown in Fig. The hook 28 is detachable using a simple tool such as a screwdriver. Accordingly, the housing 20 can be easily attached to and detached from the stand-type or wall-type heat recovery apparatus 10, thereby improving the convenience of maintenance.

According to the present invention, the dust collecting means 30 accommodates the water tank 31, the sprayer 33, and the diaphragms 35 and 36 in the housing 20 to dirt the dust in the flowing air. The water tank 31 is disposed on the bottom surface of the housing 20 and has a drain pipe 24 on the downstream side. The sprayer 33 is disposed on the upper surface of the housing 20 and connected to the water supply pipe 23 on the upstream side. The diaphragms 35 and 36 are arranged so as to form a zigzag flow path between the water tank 31 and the atomizer 33 in the up and down directions. 2, the water supplied to the water supply pipe 23 is sprayed to the sprayer 33, the dust is collected through the diaphragms 35 and 36, collected in the water storage tank 31, do.

At this time, as shown in FIG. 1, the purified water 41 may be provided on the water tank 31 to reduce the degree of pollution before draining. The water purifier 41 is also expected to maintain a constant flow rate of water flowing through the water tub 31 to reduce noise.

As a modification of the present invention, the dust collecting means 30 is provided with a movable diaphragm 36 on a spiral shaft 38 so as to be positionally movable, and which causes volume fluctuation of the adsorbent 45 on the flow path . 3 illustrates a state in which two movable diaphragms 36 are arranged to face each other with respect to one fixed diaphragm 35. As shown in Fig. The fixed diaphragm 35 is supported to allow water to flow into the water tank 31 and the movable diaphragm 36 is coupled to the left and right helix of the helix axis 38 respectively. A porous adsorbent 45 having flexibility is provided between the opposed movable diaphragms 36. Accordingly, if the opposed movable diaphragm 36 is narrowed, the pores of the adsorbent 45 are reduced and the flow resistance of the air is increased. However, it is advantageous to adsorb the fine dust or to drop off the fine dust.

On the other hand, the rotation of the movable diaphragm 36 is caused by an electric force through the driver 56 at one side or a hydraulic force through the knob 37 at the other side.

According to the present invention, the purifying means (40) is mounted on the downstream side of the dust collecting means (30) in the housing (20) to remove harmful substances from the flowing air. 1 and 2, the dust collecting means 30 is disposed on the approximately upstream side on the left side, and the purifying means 40 is disposed on the approximately right side on the downstream side. The dust collecting means 30 has a primary function of primarily removing dust and the like and the purifying means 40 has a function of removing harmful substances together with dust.

The purification means 40 is characterized in that at least one of the demister 42, the activated carbon 43 and the filter 47 is accommodated on the module box 26 which can be taken out to the exterior . The demister (42) is mainly filled with a fibrous object and can remove liquid components in the air. The activated carbon 43 absorbs harmful gas and moisture at the same time and lowers the pollution degree. The filter 47 provided on the upstream side in the housing 20 uses a prefilter and the filter 47 provided on the outside of the air supply tube 22 uses another known method. Referring to FIG. 2, the demister 42 and the activated carbon 43 are accommodated in the respective module boxes 26, and contents can be replaced without separating the housing 20 as needed. The module box 26 is a drawer structure having a net on the bottom and a packing on one side, and may be provided with a monitoring window for visually confirming the outside from the outside.

The control unit 50 further includes a controller 51 for a microcomputer circuit, a dust detector 52 for detecting the amount of variation of fine dust, And a pressure sensor 53 for detecting the flow resistance of the air. The controller 51 comprises a microprocessor, a memory, and a microcomputer circuit having an I / O interface. The dust detector 52 uses a MEMS structure capable of detecting fine dusts and is installed dispersed on the upstream side and the downstream side of the air flow path. The pressure sensor 53 is installed at one or a plurality of air flow paths to detect pressure fluctuations of the flowing air.

4, a dust sensor 52 and a pressure sensor 53 are connected to the input interface of the controller 51, and a fan motor 55, a driver 56, and an indicator 58 are connected to the output interface . The fan motor 55 is provided in the SA tube 12 and the EA tube 14 of the heat recovery apparatus 10 and the actuator 56 is provided at the end of the spiral shaft 38 and the indicator 58 is connected to the controller 51 or the like.

As an example of operation, while the outside air passes through the flow path of the housing 20, the water tank 31, the atomizer 33, the diaphragms 35 and 36, the demister 42, the activated carbon 43, 47, flows into the heat recovery apparatus 10, and is supplied to the room while being heated by the waste heat while passing through the sensible heat exchanger 16. If the controller 51 judges the sudden environment of fine dust, the actuator 56 is operated to compress the adsorbent 45 as shown by reference numeral 45 'in FIG. 3 to increase the adsorption rate. When accumulation of foreign matter such as dust progresses as the use period elapses, an audiovisual alarm is generated through the indicator 58. Accordingly, the user removes the module box 26 and easily exchanges the demister 42, the activated carbon 43, etc., so that the operation reliability for indoor air management can be improved and a pleasant environment can be maintained.

The second embodiment of the present invention proposes an apparatus for managing indoor air by a heat recovery system.

The housing 20 according to the present invention is a structure for forming a flow path of air through the intake pipe 21 and the induction pipe 61. The basic structure and function of the heat recovery apparatus 10 remain the same as in Fig. 1 described above. 5, the OA pipe 11 and the EA pipe 14 are disposed so as to face forward. The intake tube 21 communicates with the OA tube 11 and the induction tube 61 communicates with the EA tube 14 while the housing 20 is coupled to the heat recovery apparatus 10. [ The intake tube 21 and the induction tube 61 of FIG. 5 are preferred exemplary paths, and may be modified to paths of a desired direction as in the model of FIG.

On the other hand, the housing 20 can be detachably coupled to the heat recovery device 10 via the hook 28.

According to the present invention, the dust collecting means (30) receives the water tank (31) and the sprinkler (63) in the housing (20) and sinks the dust in the flowing air. The water tank 31 is disposed on the bottom surface of the housing 20 and rotatably receives the water sprayer 63 on the upper side. The water sprayer 63 has a plurality of water receiving wings on the outer surface of the wheel, and a plurality of water sprayers 63 are installed at regular intervals. The sprayer 33 may be disposed on the upper surface of the housing 20 as shown in FIG. 1 and may be connected to the water supply pipe 23 on the upstream side. Referring to FIG. 7, the water supplied to the water tank 31 is collected by the water tank 31 and then discharged to a drain pipe (not shown) by precipitating the dust of air passing through the water sprayer 63.

According to the present invention, the purifying means (40) is mounted on the downstream side of the dust collecting means (30) in the housing (20) to remove harmful substances from the flowing air. The purifying means 40 maintains the same as the first embodiment of FIGS. 1 and 2 described above. That is, at least one of the demister 42, the activated carbon 43, and the filter 47 can be accommodated on the module box 26 that can be taken out to the outside.

The dust collecting means 30 further includes a self-spraying means 60, which self-propels the power of the wind-driven fan 62 installed on the induction pipe 61 To the water sprayer 63, and the water level of the water tank 31 is kept constant by using the water supply tank 65. [0062] The wind power fan 62 is opposed to the EA pipe 14 of the heat recovery device 10 and thus is rotated by exhaust. The wind power fan 62 and the water spray pump 63 are supported by the same rotary shaft and interlocked with each other. The water supply tank 65 basically replenishes the external water at the low water level and stops the water replenishment pumping on the high water level. The water supply tank 65 maintains the end portion of the water discharge pipe at a constant height in the water tank 31 to induce water supply by gravity and water level maintenance.

On the other hand, electric power can be generated by the power of the wind-driven fan 62, although it is not shown in the figure, and it can be used for water replenishment of the water supply tank 65.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
