[0001] Ventilating device for stall [0002]

The present invention relates to an air conditioner which is installed on a roof of a housing and discharges bad odor or harmful gas generated from the housing to the outside, is capable of discharging odor and noxious gas using an external air flow, More particularly, the present invention relates to an exhaust device for exhaust use which is capable of improving the exhaust efficiency by preventing exhaust gas from flowing back into the housing.

Generally, when raising livestock, various harmful gases and odors that are harmful to livestock are generated in livestock manure inside the house, so an exhaust system is used to discharge the harmful gas or odor to the outside of the house.

The shaft exhausting apparatuses known in the technical field of the present invention include patent application registration No. 10-1143964 (multiple exhausting apparatus for indoor air conditioning), Japanese Patent Laid-Open No. 10-2012-0006216 (installation type air exhausting apparatus for exhausting radially) And Registration No. 10-0436840 (fixed ventilator).

No. 10-0436840 discloses that a plurality of induction plates penetrating through the center are coupled with a guide member so as to be spaced apart from each other by a predetermined distance, A motor having a blowing fan operated by a power source is installed inside the pedestal supporting the induction plate to be installed on the roof of the housing. When the motor can not be used, the exhaust device So that malodorous or harmful gas in the housing is discharged, and malodorous or harmful gas in the housing is forced to be discharged during the operation of the motor.

However, the above-mentioned Japanese Patent Registration No. 10-0436840 has a problem that the air flow in the atmosphere is backwashed into the housing, which requires improvement. This will be described in detail with reference to the accompanying drawings.

Fig. 1A is a cross-sectional view showing a recess of an exhausting apparatus 1 for use in an axial direction in a manner similar to that of the above-mentioned Japanese Patent No. 10-0436840, and Fig. 1B is a plan view of a guide plate 11, 12 and 13.

1A and 1B, reference numeral 15 denotes an air flow inlet passage (not shown) disposed between the guide plates 11, 13 and 13 so as to be spaced apart from each other by spacers 15a, (Not shown), and is a screw bar for connecting the guide plates 11 to 13, and reference numeral 20 denotes a guide bar for supporting the guide plates 11 to 13 so as to be fixed to the roof of the house And reference numeral 30 denotes a motor having a blowing fan installed in the base 20.

As shown in FIG. 1A, the plurality of induction plates 11 to 13 assembled in a multi-stage configuration are all punched to have the same inner diameter (R) at the center, and an air flow passage L having the same inner diameter is formed. There is a problem that the outside air flows back into the housing when the wind is introduced from the outside through the openings 11 to 13. There is a problem that the exhaust efficiency is lowered. Also, when the motor is driven and the noxious gas is forcibly discharged, The airflow generated by the air flow generated by the air flow generated by the air flow collides with the cover 14 coupled to the upper end of the induction plate 13 in a frontal direction and a vortex is severely generated in the air flow passage L, There is a disadvantage that the lifetime is shortened.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and it is an object of the present invention to improve an exhaust system installed on a roof of a housing to improve the exhaust efficiency by preventing the outside air from flowing back into the housing, So that the exhaust efficiency can be further enhanced when the gas is exhausted into the atmosphere.

Another object of the present invention is to provide an exhaust device for an axial use capable of reducing the operation load of the motor and minimizing the occurrence of vortex in the exhaust device when the exhaust is forced by the motor driving and minimizing the occurrence of the vortex.

Implementation means for implementing the object of the present invention include:

A plurality of induction plates which form an exhaust passage therein are spaced apart from each other by a predetermined distance so as to have an air flow passage, a blowing fan inside and a motor coupled to the base end to communicate with the interior of the housing In the exhaust device,

The diameter of the exhaust passage formed by the plurality of induction plates and the distance between the airflow induction plates become smaller and narrower toward the first, second, and third airflow induction plates, thereby realizing the primary object of the present invention.

The air distribution plate for dispersing the flow of the exhaust gas is further provided on the inner surface of the guide plate cover coupled to the uppermost air flow guide plate among the guide plates described above to prevent the vortex of the gas exhausted when the motor is driven, A solution can be implemented.

The axial exhaust device according to the present invention is characterized in that the diameter of the airflow passage is made smaller in order of the first to third airflow induction plates in the order of the airflow passage, Since the diameter is small, it is possible to induce the outside air to be discharged to the outside without entering the outside air by the housing.

Therefore, it is possible to prevent the external airflow from flowing back to the housing as much as possible, and conversely, when the atmospheric pressure is low, the air pressure in the housing can be exhausted to the outside through the airflow passage.

Further, according to the present invention, when the noxious gas in the housing is exhausted to the outside by the rotation of the blowing fan, the exhaust air is dispersed and discharged to the four sides of the induction plate by the air distribution plate, In addition, since the diameter of the airflow passage is gradually extended from the lowermost induction plate to the uppermost induction plate, the efficiency of discharging the harmful gas in the housing can be improved.

Therefore, the operation load of the motor can be reduced, and the exhaust efficiency can be improved.

As shown in FIGS. 2 and 3, the axial exhaust apparatus 100 of the present invention includes a base end portion 120 and an air induction portion 110.

The uppermost air induction plate and the lowermost air induction plate will be referred to as the first air induction plate 111 and the lowermost induction plate as the third air induction plate 113 , And the center induction plate is replaced with the second air induction plate 112 and will be described in terms of function.

The proximal end 120 is fixed on a roof (not shown in the figure) to support the airflow guiding part 110. The proximal end part 120 has a dust collecting box 123 having a square shape at the bottom and becoming gradually narrower toward the upper part, And a flange 122 having a fastening hole 125 for fastening the dust collecting container 123 to the roof, a cylindrical dust collecting pipe 121 coupled to the motor 130 coupled to the support, consist of.

The proximal end portion 120 is fixed to a housing roof (not shown in the drawings) by fastening a bolt (not shown in the figure) to the fastening hole 125 so as to communicate with the room of the housing, 121 are hermetically coupled to the airflow guiding part 110.

The airflow guiding part 110 is hermetically sealed to the outside diameter of the dust collecting pipe 121 to exhaust the harmful gas in the housing using the wind blowing from the outside appropriately. The center part is punched coaxially, The first to third airflow guide plates 111 to 113 each including the first to third guide vanes 111a, 112a and 113c forming the airflow passage L (see FIG. 3) and the airflow guide portion cover 114 Are spaced apart from each other by a predetermined distance.

The first to third guide vanes 111a, 111b and 1113a provided in the first to third wing plates 111 to 113 are arranged in the air flow passage L in the lateral direction of each air flow guide plate, The central portion of the first to third guide vanes 111a, 111b and 1113a is drilled to change the direction of movement to flow toward the airflow guide portion cover 114, and as shown in Fig. 4, Is gradually reduced from the wing 111a toward the third guide vane 113a and extends cylindrically at the same height and curved as the outer surface of the circumferential surface gradually decreases toward the upper side.

Reference numeral 111b denotes a through hole through which the first to third airflow guiding plates 111 to 113 pass through and a second airflow guiding plate 115 communicates between the first to third airflow guiding plates 111 to 113 And a nut (not shown) is spirally coupled to an end portion of the inner spacer which is interposed between the air flow guide plates 111 to 113 so as to be spaced apart from each other by a predetermined distance.

Accordingly, the first to third airflow guide plates 111 to 113 are spaced apart from each other by the spacer 115a to form the first to third airflow inlet channels a, b, and c, respectively.

The airflow guiding portion cover 114 prevents the inflow of rainwater into the airflow passage L and prevents the exhaust gas discharged along the airflow passage L from being radially outwardly dispersed and discharged in the airflow guiding portion 110 The central portion of the airflow guide portion cover 114 is connected to the airflow passage L through a spacer 115a and a screw rod 115 so as to be spaced apart from the first airflow guide plate 111 by a predetermined distance, And an air distribution plate 114a having a curved surface convexly in the axial direction of the air distribution plate 114a.

On the other hand, the outside diameter of each of the first to third airflow guide plates 111 to 113 described above is larger than the outer diameter of the uppermost airflow guide plate, that is, the first airflow guide plate And the third airflow guide plate 113 may be formed so that the outer diameter of the third airflow induction plate 113 is relatively small. The distance between the first to third airflow induction plates 111 to 113 may be set so that the first to third airflow introduction passages a, b , the size (spatial size) of c, is preferably such that "a> b> c".

The size adjustment of the first to third airflow inflow passages (a, b, c) is performed by intervening between the adjacent guide plates 111, 112, 113 forming the first to third airflow inflow passages (a, By adjusting the length of the spacer 115a.

A "," b ", and" c "of the first through third airflow passages (a, b, c) (L), it prevents the flow of the introduced airflow into the housing, thereby allowing the airflow to flow out through the airflow inlet passage in the opposite direction or the other direction in which the airflow is introduced, and the first to third airflow induction This is because the differences in the outer diameters of the plates 111 to 113 are useful for preventing the falling water from flowing into the air flow passage L. [

Hereinafter, the operation of the exhaust device for axial use according to the present invention will be described in detail with reference to the accompanying drawings.

First, it is assumed that the exhaust device 100 for use in the present invention is installed on the roof of the house as described above.

When the motor 130 installed in the dust collecting tube 121 is driven as shown in FIG. 5A, the noxious gas in the housing 10 is forced into the airflow passage L by the rotating blowing fan (not shown) .

At this time, the distance between the third airflow guide plate 113 and the second airflow guide plate 112, that is, the distance between the second airflow guide plate 112 and the first airflow guide plate 111, Since the exhaust gas is narrower than the second air flow passage b, the exhaust gas flows smoothly toward the first air flow guide plate 111. At this time, the negative pressure by the section of the air flow passage L becomes " (b)> the first air flow inlet passage (a) ", the exhaust gas flowing along the air flow passage L flows through the first air flow inlet passage (the first air flow inlet passage a) to the outside.

5B, when the motor 130 of the exhaust system 100 can not be used, that is, the exhaust system 100 performs an exhaust function without the motor 130 being operated, When the outside air flows into the first to third air inlet passages (a, b, c) of the guide portion 110, the airflow introduced into the air flow passage L passes through the third guide vane 113a, Since the inner diameter R of the airflow passage L is made smaller in the order of the wing 112a and the first guide vane 111a, the air is prevented from advancing toward the housing, and as a result, The outside air flowing out through the airflow inflow passage escapes and the noxious gas in the house is discharged by the Bernoulli principle by the negative pressure generated by the outside air passing through the airflow passage L. [

As described above, the axial exhaust device according to the present invention is capable of forcibly discharging noxious gas in the housing by the rotation (blowing fan) of the motor. Particularly, even when the blowing fan is stopped, The harmful gas can be discharged smoothly.

In the present invention, the airflow induction plates of the airflow induction unit are formed in a multi-stage shape, and the exhaust action smoothly advances upward (in the exhaust direction) of the airflow passage, and conversely, And the inner diameter of the guide vane is different from each other. However, the inner diameter of the guide vane may be varied depending on the size of the housing and the installation environment.
