DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
(Embodiment 1-1) The heat insulating damper of the present invention comprises a shield plate 100 formed of a plate 110 and a drive shaft 120 protruding from one side of the plate, an actuating part 200 ), A driving part (300) protruding from the driving shaft and driving the driving shaft simultaneously. In an air circulator or the like, a damper is used for opening and closing the air flow. The heat insulating damper is installed on the air flow pipe. The heat insulating damper of the present invention comprises a plurality of shielding plates, and a plurality of shielding plates are installed in the heat insulating damper operating portion. The plurality of blocking plates are reciprocally rotated in the range of 90 占. That is, the closed state is that each of the blocking plates is in the 0 ° state, and the open state is that each blocking plate is in the 90 ° state.
(Example 1-2) The heat insulating damper of the present invention comprises a first step (111) formed at one end of the shut-off plate, and a second step (112) formed at the other end of the shut-off plate do. Even if a plurality of shielding plates are shielded, a minute space is generated between the shielding plate and the shielding plate. The micro-space may be an inflow passage of outside air in spite of the closing of the blocking plate. Therefore, at each end of each shield plate, a step smaller than the shield plate thickness is formed so as to block external inflow after operation of the shield plate. The step difference is divided into a first step of the one end of the blocking plate and a second step of the other end of the blocking plate. The first and second steps have opposite projecting positions. Therefore, when the blocking plate is closed, mutually overlapping portions of the first step and the second step are generated, and this does not cause micro space.
(Embodiment 1-3) In the embodiment 1-2, the heat insulating damper of the present invention includes a seal 113 attached to one surface of the first step. External air may be introduced into the first and second steps even if the respective blocking plates are closed and the first and second steps of the respective blocking plates intersect with each other. To prevent this, seal between the first and second steps should be sealed. The sealing preferably utilizes a sponge. However, it can be used as a substitute for a sponge, and it can be used as an equivalent range if it has the purpose and effect of shielding a minute space. The material used for the sealing may additionally include magnetic force. That is, when the sponge having the magnetic force at the first step comes close to the second step of the other shield plate, a magnetic force is applied by the magnetic force. The interior of the second step receives magnetic force to receive the metal plate 117.
(Embodiment 1-4) In the embodiment 1-3, the heat insulating damper of the present invention is formed on the second step difference surface and includes the sealing groove 114 described above. The first step and the second step are surface-contacted. In particular, a sealing groove is formed in the second step so that the sealing formed in the first step can be inserted into the second step. This improves the blocking effect by implementing the combination of the groove and the projection.
(Embodiment 1-5) The heat insulating damper of the present invention includes the first heat insulating material 115 attached to one surface and / or the other surface of the shutoff plate in Embodiment 1-1. The insulation damper must block the temperature as well as the air flow. Therefore, the first heat insulating material can be adhered to one surface or both surfaces of the blocking plate to enhance the heat insulating effect.
(Examples 1-6) In the heat insulating dampers of the embodiments 1-5, the heat insulating damper includes a second heat insulating material 116 inside the shutoff plate. The insulation damper must block the temperature as well as the air flow. Therefore, the second insulation material is inserted into the inside of the shielding plate to increase the heat insulation effect. When the second insulating material is accommodated in the shielding plate, the air flow is prevented from being disturbed by the insulating material, and the insulation material can be prevented from being damaged by contact with the foreign matter.

(Embodiment 2-1) In the heat insulating damper of embodiment 1-1 according to the present invention, the driving unit includes power transmission means 310 coupled with a plurality of driving shafts projecting through. The operating portion of the heat insulating damper accommodates a plurality of shielding plates, and the plurality of shielding plates are simultaneously operated at the same angle. To this end, each blocking plate forms a driving shaft, and the driving shafts protrude to the driving unit. Thus, the protruding drive shafts are reciprocated at the same angle to operate the shield plate simultaneously. The power transmission means simultaneously drives the drive shafts at the same angle.
(Embodiment 2-2) In the heat insulating damper of embodiment 2-1 according to the present invention, the power transmitting means includes a driven gear 311 coupled to each drive shaft, a driven gear coupled to the driven gear, And an interlocking gear 312 for interlocking the power. A plurality of drive shafts protruding from the operating portion are engaged with the respective driven gears. Each driven gear has the same size and shape. One driven gear is meshed with the two driven gears so that each driven gear rotates in the same direction. Therefore, the number N of the interlocking gears is one less than the number N of the driven gears. That is, a plurality of driven gears can be rotated in the same direction by a plurality of interlocking gears. The power transmission means actuates a rotational force to the driven gear or the interlocking gear. As a means for substituting for the driven gear and the interlocking gear, a belt and a pulley are alternately used. Each of the drive shafts is coupled to a pulley, and each of the pulleys is coupled to a belt. By rotating the belt, each of the pulleys is rotated to operate the shutoff plate. The belt uses a timing belt to give accurate turning force and operability, and a pretensioner is used to apply a constant tension to the belt. The use of a friction wheel, a wire drive, a linkage, a bevel gear, a worm gear, and the like as in the gear driving method and the belt driving method has the same principle of solving the problem of simultaneously operating the blocking plates, And it is an alternative configuration that can be easily changed and implemented by an ordinary technician.
(Embodiment 2-3) A heat insulating damper according to Embodiment 2-1 of the present invention comprises an electric motor 314 for applying a rotational power to the power transmitting means, a unit controller 315 for controlling driving of the electric motor ). Driving the driven gear and / or the interlocked gear utilizes an electric motor. The drive control of the electric motor is operated by the unit controller. The rotation direction and the rotation amount of the electric motor can be controlled by the control signal of the unit controller.
(Embodiment 2-4) A heat insulating damper according to Embodiment 2-1 is provided with a wire pulley 321 coupled to a driving shaft fixed to the driven gear or the interlocking gear, A spring 322 that provides a torsional elastic force to the wire pulley; and an actuation wire 323 that is wound around the wire pulley circumferential surface to some extent. A driving motor and a wire driving device are required for manual operation of the insulating damper blocking plate. The rotating driven gear or the interlocking gear must be rotated by the rotation of the wire pulley, which is fixedly coupled to the driving shaft. That is, the driven gear and the driven gear can be driven by the rotation of the wire pulley. The outer pulley is wound on the outer circumferential surface of the wire pulley, and the wire is fixed to the outer pulley. In other words, the outer ring pulley can be rotated by the operation of the wire. A spring is used to return the rotated wire pulley. Preferably, a torsion coil spring is used. One side of the torsion coil spring is connected to the wire pulley and the other side is fixed. That is, the rotation return of the wire pulley can be realized by a torsion coil spring. A wire-wound wire guide is formed to prevent the wire from coming off the pulley. The wire thus runs along the wire guide and is not released by the rotation of the wire pulley.

(Embodiment 3-1) In the heat insulating damper of the embodiment 1-1, the heat insulating damper of the present invention includes an operating section cover 210 covering one side of the operating section, and a driving section cover 340 covering one side of the driving section . The operating portion accommodates a plurality of shield plates. In order for a plurality of shield plates to be coupled to the actuating part, an actuating part cover is required. Therefore, the operation cover is used for assembling and connecting the shield plate in the assembly process, or for replacing the shield plate in the repairing process. Power transmission means is located in the drive section. That is, a plurality of gears and shafts are coupled and exist in an exposed state to the outside. To prevent this, a drive cover is formed to prevent external exposure of the mechanical structure.
(Example 3-2) In the heat insulating damper of Example 3-1 according to the present invention, the heat insulating damper according to Example 3-1 includes: an actuating bolt 211 for fastening the actuating portion cover and the actuating portion; And a fastening bolt (341). The operating cover and the operating part are bolted together. The driving section cover and the driving section are bolted to each other. In addition to the bolt connection, an equal range of fastening means may be substituted.
(Embodiment 3-3) In the heat insulating damper of embodiment 3-1 according to the present invention, the heat insulating damper of the present invention comprises a first support groove 212 formed in the operation cover and formed of a plurality of grooves, And a second support groove (213) formed in the operation part and corresponding to the first support groove.
(Embodiment 3-4) In the heat insulating damper of the embodiment 3-3, the heat insulating damper of the present invention comprises a first support 130 formed on the other side of the shield plate and inserted into the first support groove, And a second support 140 formed on one side and coupled to the second support groove. Even if a plurality of shielding plates are shielded by the heat insulating damper, air flow is generated because a minute space is formed at one side and the other side of the shielding plate. In order to prevent this, a disk-shaped first support member and a second support member are integrally formed on both sides of the blocking plate. The operating lid forms a first support groove for receiving the first support and a second support groove is formed inside the operation portion for receiving the second support. That is, the first and second support grooves of the actuating part and the actuating part cover and the first and second support parts of the shielding plate are fitted and fitted, thereby blocking the generation of microstructures on both sides of the shielding plate. The first support member and the first support member are inserted into the oilless bearing because friction may be generated. Or a Teflon material having a low friction coefficient or a Teflon material. The first and second support grooves of the actuating portion cover and the actuating portion are in contact with the circumference. The two first and second support contact positions having the same rotation direction form different operating directions, which causes friction. In order to prevent this, the first and second support rods are formed with the anti-friction grooves 150 in the range of 90 [deg.]. The friction preventing grooves are provided to prevent friction at a reverse contact position generated in the same rotational direction.

(Embodiment 4-1) In the heat insulating damper of embodiment 2-1, a plurality of the heat insulating dampers are formed, and simultaneously driving the power transmitting means from one power source. One insulation damper implements a barrier plate formed in a row. That is, the air flow can be blocked by closing the closing plate. However, in the case of double shielding in which two heat insulating dampers are combined, the effect of heat shielding and noise shielding as well as air flow shielding is high. Therefore, it is desirable to realize a double insulation damper. When two heat insulating dampers are in close contact with each other and each of the driving parts is driven by one power source, the effect of the blocking plate control is high.

(Embodiment 5-1) In the embodiment 4-1, the heat insulating damper of the present invention includes an indoor air discharge flow path 510 and an outdoor air introduction flow path 520 in an intersecting manner, and a heat exchanger 530 And the heat insulating damper according to any one of claims 2 to 4 is included in the indoor discharge flow passage and / or the outdoor air introduction flow passage. When the human living space is enclosed, the internal air causes an increase in the carbon dioxide and oxygen deficiency. Therefore, indoor air is discharged and fresh outdoor air must be introduced into the room. However, if the indoor air in the cooling / heating condition is discharged outdoors and the outdoor air at room temperature enters the room, energy loss is inevitable. In order to prevent such energy loss, the heat exchanger is mounted on the air circulator, and the heat exchanger can increase or decrease the temperature of the outdoor air by the thermal equilibrium of the indoor air and the outdoor air, thereby reducing the cooling and heating cost. Recently, there are many yellow dust and fine dust in the atmospheric environment. The air circulator is equipped with a filter to block entry of such harmful components into the room. Even when the air circulator is not in use, the discharge passage and the introduction passage communicate with each other indoors and outdoors, so that forced entry of the foreign matter may occur. In order to prevent this, a damper is mounted on the discharge passage and the intake passage, and the passage is blocked while the air circulator is not in use. The heat exchanger in which the low temperature and the high temperature air are contacted causes the moisture of the hot side air to cohere and to generate condensation water. The number of condensation inside the circulator can cause corrosion, equipment damage, and bacteria. To prevent the generation of dew condensation, the air flow must be shut off while the air circulator is not in use. Therefore, the heat insulating damper of the present invention is installed on the inlet flow path and the exhaust flow path to shut off the temperature as well as the air entering the heat exchanger.
(Example 5-2) In the heat insulating damper of Example 5-1 of the present invention, the heat insulating damper is formed outside the indoor discharge flow passage and / or the outdoor air introduction flow passage. The majority of air circulators currently installed on the market form four air inlet and outlet ducts. The heat insulating damper of the present invention may be mounted on the inflow and outflow conduits to block the entrance of the outside air and the inside air while the air circulator is not in use. For this purpose, an insulation damper is mounted outside the air circulator.
(Example 5-3) In the insulating damper of Example 5-2 of the present invention, in order to couple with the indoor public discharge flow passage and / or the outdoor piping of the outdoor air injection oil, the air circulator is connected to the inlet and the flange 540) so that the air circulator and the heat insulating damper are detachably attached. In order for the insulation damper to be installed in existing equipment, it is necessary to form a satisfactory coupling condition with the existing equipment. Accordingly, a flange is formed at both ends of the heat insulating damper of the present invention, and the flange is joined to the air circulating duct.
