The single air supply and exhaust indoor duct 140 is a duct connected to the ventilation device 110 on one side and disposed in the indoor space of the building, and the supply and exhaust are alternately performed. In other words, as shown in FIGS. 2 and 3, air supply and exhaust may alternately proceed through the single air supply and exhaust indoor duct 140. Therefore, it is possible to simplify the structure.

One side of the single air supply and exhaust indoor duct 140 is provided with a supply and exhaust bell 160. The number of bells 160 for supply and exhaust may be appropriately selected according to the size of the indoor space. Air may be discharged into the room when air is supplied as shown in FIG. 2 through the supply and exhaust bell 160, or indoor air may be sucked during exhaust as shown in FIG. 3.

Various types of bells 160 for supply and exhaust may be applied, and in this embodiment, the bell 160 for supply and exhaust of the same type as shown in FIG. 8 is applied. Of course, the structure of FIG. 8 is only an example, and the scope of the present invention is not limited thereto.

It may include a cap shaft 165 to be fixed to and a supporter 166 for supporting the cap shaft 165 to the air filter module 163.

Since the end of the second bell body 162 is curved and the adjustment cap 164 is disposed therebetween, a vortex of air does not occur during supply or exhaust, and a smooth air flow can be provided. The air filter module 163 may be a replaceable HEPA filter.

One side of the single air supply and exhaust outdoor duct 150 is connected to the device housing 111 of the ventilation device 110 and the other side is disposed outside the building, and supply and exhaust alternately with the single air supply and exhaust indoor duct 140 It forms a place where it proceeds.

Of course, in some cases, there may be two or more single air supply/exhaust outdoor ducts 150, but applying it as a single pipe as in the present embodiment may be advantageous in simplifying the structure. A cap grill 157 is provided at the end of the single air supply/exhaust outdoor duct 150. When the opening of the cap grille 157 faces downward, it is possible to block the inflow of rainwater.

The single supply/exhaust indoor duct 140 and the single supply/exhaust outdoor duct 150 are provided with first and second non-powered dampers 142 and 152 respectively.

The first and second non-powered dampers 142 and 152 for both air supply and exhaust may have the same structure as only different positions, and may be applied in the same structure as in FIG. 9. Of course, the structure of FIG. 9 is only an example, and the scope of the present invention is not limited thereto.

Referring to FIG. 9, both of the first and second non-powered dampers 142 and 152 are respectively inserted into the single air supply and exhaust indoor duct 140 and the single air supply and exhaust outdoor duct 150, but the air flow passage 144b is A damper ring 144 to be formed, an opening/closing film 145 for opening and closing the air flow path 144b in the damper ring 144 according to air flow without power, and a rotation shaft 146 forming a rotation axis of the opening/closing film 145 Includes. A plurality of reinforcing ribs 144a are provided on the outer wall of the damper ring 144. Therefore, the damper ring 144 can be reinforced.

Since the opening/closing membrane 145 operates with no power, there is an advantage that a separate power is not required, and there is an advantage in cooling and heating since the air flow path 144b is blocked normally. Of course, it can also prevent the invasion of insects.

In addition, an electric damper 170 may be provided around the non-powered damper 152 for both air supply and exhaust in the single air supply/exhaust outdoor duct 150. Although the electric damper 170 is not necessarily applied, when the electric damper 170 is applied, supply and exhaust are forcibly blocked, and advantageous effects may be provided.

Various types of electric damper 170 may be applied, and in this embodiment, the electric damper 170 of the shape shown in FIG. 10 is applied. Of course, the structure of FIG. 10 is only an example, and the scope of the present invention is not limited thereto.

Referring to FIG. 10, the electric damper 170 includes a plurality of power blades 172 rotatably disposed in the air flow space 150a in a single air supply/exhaust outdoor duct 150, and a power blade 172 therein. It includes a rotation shaft 173 forming the rotation axis of the rotation axis, and a blade rotation driving unit 174 for rotating the power blade 172 through the rotation shaft 173.

The heat storage element 155 is provided in the single air supply/exhaust outdoor duct 150, and serves to store heat discharged from the room during exhaust and to perform an endothermic action with external air during supply.

The heat storage device 155 is known to have superior heat storage performance for heat recovery above all else. In other words, it heats up the heat emitted from the room during exhaust. During the supply of air, the outside air passes through the heat storage device 155 and an endothermic action proceeds.

When conducting a heat exchange performance test of the heat storage element 155, it has been confirmed that the cooling and heating efficiency of 70% or more can be provided. In particular, since the heat storage device 155 is made of alumina ceramic, it can be used semi-permanently. Therefore, maintenance such as replacement is not required, which is advantageous for cost reduction.

Meanwhile, in the multifunctional ventilation system 100 according to the present embodiment, a pollution level detection unit 181, a timer 182, and a system controller 190 are further mounted to control the system.

The pollution level detection unit 181 is provided in the indoor space and detects the pollution degree of the indoor space. The pollution level at this time detects the amount of carbon dioxide or fine dust. Of course, it is also possible to detect the remaining amount of pollutants other than carbon dioxide or fine dust.

The timer 182 sets the operating time of the air supply fan 112 and the exhaust fan 116. Of course, the timer 182 may exist as a separate device or may exist as a part of the system controller 190.

The system controller 190 performs the operation of the air supply fan 112, the exhaust fan 116, the 3-way guide damper unit 130, and the electric fan damper 138 based on the detection information of the pollution level detection unit 181. It is controlled by an organic mechanism.

Specifically, in this embodiment, the system controller 190 includes the air supply fan 112, the exhaust fan 116, and a three-way guide so that the exhaust mode first proceeds for a first time predetermined by the timer 182. After controlling the operation of the damper unit 130 and the electric fan damper 138, the air supply fan 112, the exhaust fan 116, and the three-way guide damper unit 130 so that the air supply mode proceeds after the first time elapses. ) And the operation of the electric fan damper 138 is controlled.

As such, the system controller 190 controls the operation of the air supply fan 112, the exhaust fan 116, the 3-way guide damper unit 130, and the electric fan damper 138 so that the air supply mode and the exhaust mode alternately proceed. To control, there is an advantage of preventing condensation by applying the heat storage device 155 together with the control.

The system controller 190 performing this role may include a central processing unit 191 (CPU), a memory 192 (MEMORY), and a support circuit 193 (SUPPORT CIRCUIT).

The central processing unit 191 is based on the detection information of the pollution level detection unit 181 in this embodiment, the air supply fan 112, the exhaust fan 116, the three-way guide damper unit 130, and the electric fan damper ( 138) may be one of various computer processors that can be applied industrially in order to control the operation by an organic mechanism.

The memory 192 (MEMORY) is connected to the central processing unit 191. The memory 192 can be installed locally or remotely as a computer-readable recording medium, and can be easily used such as random access memory (RAM), ROM, floppy disk, hard disk, or any digital storage type. It may be at least one or more memories.

The support circuit 193 (SUPPORT CIRCUIT) is combined with the central processing unit 191 to support typical operation of the processor. The support circuit 193 may include a cache, a power supply, a clock circuit, an input/output circuit, a subsystem, and the like.

In this embodiment, the system controller 190 includes the air supply fan 112, the exhaust fan 116, and the 3-way guide damper unit 130 so that the exhaust mode first proceeds for a first time predetermined by the timer 182. And after controlling the operation of the electric fan damper 138, the air supply fan 112, the exhaust fan 116, the three-way guide damper unit 130 and the electric fan damper so that the air supply mode proceeds after the first time elapses. The operation of 138 is controlled, and such a series of control processes may be stored in the memory 192. Typically software routines may be stored in memory 192. Software routines can also be stored or executed by other central processing units (not shown).

Although the process according to the present invention has been described as being executed by a software routine, it is also possible that at least some of the processes of the present invention are performed by hardware. As such, the processes of the present invention may be implemented by software executed on a computer system, by hardware such as an integrated circuit, or by a combination of software and hardware.

Hereinafter, the operation of the multifunctional ventilation system 100 according to the present embodiment will be described.

When the multi-function ventilation system 100 according to the present embodiment is operated, the system controller 190 performs the exhaust mode (see FIG. 3) for 2 minutes. The supply fan 112, the exhaust fan 116, and the three-way It controls the operation of the guide damper unit 130 and the electric fan damper 138. Accordingly, an exhaust mode (refer to FIG. 3) leading to the single supply/exhaust indoor duct 140, the exhaust duct part 117 of the device housing 111, and the single supply/exhaust outdoor duct 150 may proceed.

As described above, if the exhaust mode (see FIG. 3) is performed for 2 minutes before supplying air, for example, there is an advantageous effect in cleaning the pipe. That is, if foreign matter accumulates in the single supply/exhaust indoor duct 140 or the single supply/exhaust outdoor duct 150, there is no way to clean it unless the system is disassembled. There is a problem in that fine dust and contaminants that are harmful to the human body are accumulated in the single air supply and exhaust indoor duct 140 or the single air supply and exhaust outdoor duct 150, thereby generating mold and bacteria. The heat exchange element 155 and the filter member 114 are a part through which the incoming external air passes, and are an optimal place where viruses and bacteria can be generated. When the ventilation device 110 is driven, there is a concern about infection of bacteria, which is a concern for the elderly and children. , Or may be fatal in pregnant women.

If the exhaust mode is performed first, as in this embodiment, the pipe can be cleaned. In the exhaust mode, the heat storage action by the heat storage element 155 proceeds. The exhaust mode for pipe cleaning may be referred to as a cleaning mode. In the cleaning mode, fine dust or pollutants from the single air supply and exhaust indoor duct 140 or the single air supply and exhaust outdoor duct 150 may be discharged to the outside.

When the cleaning mode for a predetermined time is completed, the air supply mode (refer to FIG. 2) proceeds. That is, an air supply mode (refer to FIG. 2) leading to the single air supply and exhaust outdoor duct 150, the air supply duct 113 of the device housing 111, and the single air supply and exhaust indoor duct 140 may proceed.

In this system, air supply and exhaust are not performed simultaneously, but alternately proceeds in this system, such as the exhaust mode again when the air supply mode is completed for a predetermined time, thereby enhancing the ventilation effect. Viruses or bacteria that may be included in the air entering from the outside can be sterilized with an ultraviolet lamp to prevent infection caused by viruses entering the room. In addition, the filter member 114 and the ultraviolet lamp installed inside the ventilation device 110 sterilize areas where viruses and bacteria are easily generated so that fresh and clean air is introduced into the room.

According to this embodiment, which acts based on the structure as described above, ventilation can be performed more effectively than before while reducing cooling and heating energy loss, as well as sterilizing viruses that may be contained in outdoor air and introducing them into the room. So you can prevent infections caused by viruses.

In particular, if the supply and exhaust operation is performed while using the heat storage element 155 as in the present embodiment while alternately operating supply and exhaust, it is possible to effectively perform ventilation while preventing condensation from occurring, thereby preventing the occurrence of mold. Not only can it be eliminated, but it is also possible to fundamentally block the risk of fire caused by the use of a preheater.

12 is an enlarged view of a main part of FIG. 3 according to another embodiment of the present invention. 12 is a view in which a component cleaning liquid supply 230 is added unlike FIG. 5, and the remaining components are the same as in FIG. 5. Therefore, for convenience of explanation, descriptions of general operations of the remaining components except for the component cleaning liquid supply 230 will be omitted.

12, unlike FIG. 5, the ventilation device 110 may further include a cleaning liquid supply 230. The cleaning liquid supply 230 is implemented in the exhaust fan 116. Depending on the embodiment, the cleaning liquid supply 230 may be implemented outside or at the inlet of the exhaust fan 116. The cleaning liquid supply 230 is used only in the cleaning mode. In the case of fine dust, the fine dust may not be completely removed only by the exhausted air. Therefore, in order to completely remove the fine dust, a chemical containing moisture may be sprayed from the cleaning liquid supply 230. The drug may be a chemical substance or a natural substance as an ingredient harmless to the human body. Moisture can be combined with fine dust and carried outward. The difference between the cleaning mode and the exhaust mode is that the cleaning liquid supply 230 does not operate in the exhaust mode, but the cleaning liquid supply 230 operates in the cleaning mode.

As described above, the present invention is not limited to the described embodiments, and it is apparent to those of ordinary skill in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, it should be said that such modifications or variations belong to the claims of the present invention.
