Description

Single ventilating apparatus with heat-exchange function}

The present invention relates to a ventilator for ventilating the room, and more particularly, to indoor air that has a temperature similar to that of the indoor air exhausted through heat exchange between the indoor air exhausted in the process of being ventilated by one blower and the external air supplied. The present invention relates to a single blower having a heat exchange ventilation function which can be supplied to a.

In general, a building such as an apartment or a house does not have a separate ventilation device. Therefore, for indoor ventilation, ventilation must be performed through a window such as a living room. However, the ventilation through the opening of a window such as a living room has the advantage that the outside air is rapidly introduced into the room and the air is quickly ventilated, but since most of the air cooled and heated in the room is easily lost, the temperature of the room changes rapidly. As a result, there is a problem in that energy cannot be efficiently used, such as restarting a cooling / heating device such as a boiler or an air conditioner.

Therefore, in most homes, ventilation methods through the opening of windows such as the living room are avoided as much as possible. As a result, the air in the room becomes cloudy or contaminated, which has a harmful effect on the human body, such as raising the possibility of respiratory diseases such as cold and asthma. A problem has occurred.

In addition, in recent apartments and houses, due to the development of construction technology, the encapsulation of the interior is greatly improved, so that ventilation is not performed without opening windows. The possibility of respiratory diseases such as a cold has been further deepened.

On the other hand, in order to solve some of the problems described above, some households have purchased a separate air purifier, an air conditioner or a hot air blower, and ventilated indoor air through a blowing function included in the cold / hot air device. However, such separate cold and warm air devices are expensive items that amount to millions of won, causing a lot of financial burden.

In addition, in the case of the ventilation function, the hot and cold air is introduced as it is without heat exchange in the case of the ventilation function, and thus a problem of rapidly changing the room temperature is suddenly lowered or raised. There was a problem that provides a sense of rejection to the satisfaction of cold and warm air devices.

In addition, in some buildings such as high-end apartments and villas, ducts are constructed for each furniture, such as central air-conditioning (air-conditioning) buildings, to allow ventilation, cooling, and heating. However, in the case of a building such as a central air-conditioning apartment, it requires a lot of manpower and cost to operate the air conditioning system in addition to the construction cost according to the construction of the air conditioning system. .

On the other hand, in order to solve the above problems, a separate heat ventilation unit has been developed, but these heat ventilation units are mostly operated by two fans, and are large in size and require a large installation area. Likewise, since the price is high, problems remain economically.

Figure 1 shows an example of such a conventional total heat exchange type ventilation device (domestic registered patent 10-0343036), the electrostatic precipitator 20, the heat exchanger 30 and the external air supply fan 40 and the indoor air Exhaust fan 50 is configured to supply the outside air or to exhaust the indoor air.

First, when the external air supply fan 40 is operated to supply external air, the external air passes through the external air intake hole H1 to the electrostatic precipitator 20, the heat exchanger 30, and the external air supply fan ( 40 is sequentially introduced into the room through the indoor air supply hole (H2), such foreign air is removed by the electrostatic precipitator 20, the heat exchange is made by the total heat exchanger (30). You lose.

When the indoor air exhaust fan 50 is operated to exhaust the indoor air to the outside, the indoor air is exhausted through the bypass air passage 60, the heat exchanger 30, and the indoor air through the indoor air suction hole H3. Exhausted to the outside while passing through the hole (H4), the indoor air passing through the heat exchanger 30 is exhausted to the outside while conducting heat to the heat exchanger (30).

However, the conventional electrothermal exchange type ventilator 10 is supplied with and exhausted by the individual operation of the external air supply fan 40 and the indoor air exhaust fan 50, so the number of parts is increased to increase the production cost, noise This occurred badly, and due to the large number of parts and structural characteristics, it is impossible to produce a small size, which is not suitable as a ventilation device of a general apartment or house.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to provide a clean external air through the air supply and exhaust and heat exchange with a single blower through filtering To provide a heat exchange ventilation function single blower.

Another object of the present invention is to provide a heat exchange ventilating function single blower that can more easily maintain the heat exchange medium in which foreign matters such as dust accumulate.

In addition, another object of the present invention is to provide a heat exchange ventilation function single blower that can be reduced and the number of parts and noise, and to produce a more compact and low production cost of the product because the air supply and exhaust is made through a single blower.

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

Figure 2 is a perspective view of a heat exchange ventilation function single blower according to the present invention, in particular the perspective view showing the air flow according to the operation of the internal structure and the ventilation device, Figure 3 is a chamber of the heat exchange ventilation function single blower according to the present invention Front sectional view showing a case.

As shown, the present invention consists of a single blower 400 having a chamber case 200, an internal and external air separator 300, and one impeller 510. First, the chamber case 200 is introduced into the outside air and the indoor air, to form the outside air inlet hole 210 and the indoor air inlet hole 220 on both sides for the inflow of the outside air and the indoor air, respectively, the outside air The inlet hole 210 and the indoor air inlet hole 220 were connected to the external air inlet duct D1 and the indoor air inlet duct D2, respectively.

In addition, the chamber case 200 forms a separator 230 on an inner upper surface and a lower surface to form an outside chamber 240 and an inside chamber 250, through which the outside air and the interior of the chamber case 200 flow into the chamber case 200. Air was prevented from mixing. In addition, a separator plate coupling hole 260 is formed at the center of the front and rear surfaces of the chamber case 200.

The internal and external air separator 300 is installed in the separation plate coupling hole 260 inclined in the same manner as the inclination direction of the separator 230, and distinguishes between the outside air and the indoor air introduced into the chamber case 200. It serves to guide to the single blower 400 side. In particular, the internal and external air separation plate 300 is installed so as to be detachable to the separation plate coupling hole 260 of the chamber case 200 because the lid 310 having the handle 320 is integrally installed.

The single blower 400 is for exhausting and supplying the outside air and the indoor air as shown in FIGS. 5 and 6 and includes a motor 500, a blower duct 410, and a heat exchange blower. First, the motor 500 is installed on the rear side of the single blower 400 as a driving source of the single blower 400.

The blower duct 410 is a casing in which the heat exchange blower is installed. The blower duct 410 forms a separator insertion hole 415 on the front surface thereof so as to match the separator coupling hole 260. A portion of 300) can be inserted. In addition, the exhaust guide duct 420 and the air supply duct 430 are installed at both sides, respectively, and are connected to the external air supply duct D4 and the indoor air exhaust duct D3.

The heat exchange blower is installed inside the blower duct 410 to exchange heat between the outside air guided by the internal / external air separator 300 and the indoor air to supply the outside air to the room, and the indoor air to the outside. It serves to exhaust. As an example of the heat exchange blowing means, the impeller 510 and the heat exchange medium 520 are used in the present invention.

First, the impeller 510 is rotated by the driving force of the motor 500 to blow external air and indoor air of the internal and external air separation plates 300 to the external air supply duct D4 and the indoor air exhaust duct D3. Will be At this time, the impeller 510 is preferably formed in a cylindrical shape so that a portion of the internal and external separator 300 is accommodated.

In addition, the heat exchange medium 520 is installed inside the impeller 510. Since the heat exchange medium 520 is formed to have a diameter slightly smaller than the inner diameter of the impeller 510, as shown in the partially enlarged cross-sectional view of FIG. The spacing is maintained, and the rotation is made through the air flow according to the rotation of the impeller 510. Therefore, the heat exchange medium 520 absorbs heat contained in the exhausted indoor air, transfers heat to the supplied external air, and also filters out foreign substances such as dust contained in the external air. .

As an example of the heat exchange medium 520, a polyester filament or the like is used in the present invention, and a wire (not shown) is installed in the heat exchange medium 520 to maintain its shape. However, the heat exchange medium 520 may use other materials having excellent thermal conductivity and filtering in addition to the polyester filament.

Referring to the operation and effect of the present invention configured as described in detail as follows.

As shown in FIG. 6, the heat exchange ventilator of the present invention is fixedly installed to an outer wall structure C such as a balcony by using a bolt B and a bracket R, and allows a resident to ventilate indoor air such as a living room. In order to operate the motor 500 of the single blower 400 by a switch or a remote controller (not shown), the impeller 510 is rotated by the driving of the motor 500 as shown in FIG. It absorbs the air outside and the indoor air contaminated.

Therefore, the indoor air contaminated with external air is sequentially subjected to the external air inlet duct D1, the indoor air inlet duct D2, the chamber case 200, and the internal and external air separators 300 by the suction force of the impeller 510. In this case, the outside air and the indoor air passing through the internal and external air separation plate 300 is intaken toward the impeller 510 while maintaining a state in which the separation plate 300 is clearly separated as shown in FIG. 4. After the heat exchange and the filtering are performed by the heat exchange medium 520, the outside air and the indoor air are supplied and exhausted through the external air air supply duct D4 and the indoor air exhaust duct D3 through the impeller 510, respectively.

The heat exchange process according to the operation of the impeller 510 will be described in more detail with reference to FIGS. 4 and 5. As the impeller 510 operates, the indoor air of the internal / external separator 300 passes through the heat exchange medium 520. In this process, the heat exchange medium 520 is located between the impeller 510 and the separator 300 by the flow of air intake to the impeller 510 and centrifugal force.

Therefore, the heat exchange medium 520 is rotated due to the air flow due to the rotation of the impeller 510 and absorbs the heat energy contained in the indoor air to be delivered to the outside air which is intaked.

In addition, the indoor air from which heat energy is transferred is passed through the impeller 510 to the outside through the indoor air exhaust duct (D3), and the external air received the thermal energy to the room through the external air supply duct (D4). The external air is supplied at a temperature similar to that of the room air through heat exchange, so that the room temperature is hardly changed.

In more detail through the example of winter and summer, in the case of winter, the warm heat energy of the indoor air to be exhausted is transferred to the outside air taken in through the heat exchange medium 520, so that the exhausted indoor air and the external air to be supplied The temperature will be similar. Therefore, even if the air is supplied to the room through the external air supply duct (D4), the indoor air does not drop rapidly, thereby reducing the operating time of the heating device such as the boiler or the hot air heater, thereby preventing waste of energy.

On the other hand, even in summer, since the cool heat energy of the indoor air exhausted is transferred to the outside air taken in through the heat exchanger, the indoor air exhausted and the external air supplied are similar in temperature. Therefore, even if the outdoor air is supplied to the room through the external air supply duct (D4), the indoor air is not rapidly increased, thereby reducing the operating time of the cooling device such as an air conditioner to prevent waste of energy.

In addition, since the heat exchange medium 520 of the present invention is made of polyester filament or the like, the foreign material such as dust contained in the outside air that is inhaled during operation of the impeller 510 is filtered, thereby cleaning the outside air more indoors. I'm in the air.

Furthermore, since the heat exchange medium 520 of the present invention is installed to be accommodated through the chamber case 200, it is very easy to maintain and manage the foreign matter such as accumulated dust and the like. Referring to the storage process for the maintenance of the heat exchange medium 520 in more detail, first, the internal and external air separation plate 300 inserted into the chamber case 200 through the handle 320, and then the chamber case ( The heat exchange medium 520 can be easily taken out through the separation plate coupling hole 260 and the separation plate insertion hole 415 of the blowing duct 410 formed in the 200. The removed heat exchange medium 520 is easy to maintain because it is easy to remove foreign matters such as dust by removing the accumulated dust and the like or by washing with water.

On the other hand, since the heat exchange medium 520 from which foreign substances such as dust are removed may be inserted into the impeller 510 again through the separator coupling hole 260 of the chamber case 200, it is very useful in terms of economics. Do. In particular, since the heat exchange medium 520 can be easily managed by a housewife or a resident, the maintenance and management cost is greatly reduced, and the heat exchange ventilator is very useful in constructing an apartment or a house.

In particular, the present invention has a structure in which the ventilation is performed by one motor 500 and the impeller 510, as compared to the total heat exchange type ventilation apparatus 10 in which the air supply fan 40 and the exhaust fan 50 are installed as in the related art. The air path becomes simpler. Therefore, since the smooth air flow is realized, the energy saving and ventilation performance is more effectively improved.

In addition, the present invention, since only one impeller 520 is used as the main cause of the noise, the noise is significantly reduced as compared to the conventional heat exchanger type ventilation apparatus 10, and the miniaturization of the product is possible through the reduction of parts. Therefore, the present invention can realize excellent energy saving, low noise, convenient maintenance and miniaturization of the product, so that the present invention can be applied to a ventilation device suitable for a residential environment such as an apartment or a house.

As shown in FIG. 6, the outer grill G1 is installed at each end of the indoor air exhaust duct D3 and the external air inlet duct D1. The shapes of the outer grill G1 are opposite to each other. Exhaust and intake were made to prevent mutual interference between indoor and outdoor air, and to open in one direction to minimize damages such as backwind and rainwater.

In the present invention, the indoor grill (G2) is also installed at the ends of the external air supply duct (D4) and the indoor air inlet duct (D2), the indoor grill (G2) is the interference between the air supply and the intake air and indoor air mutually And to control the direction of the air flow in the room serves to achieve a more smooth ventilation.

On the other hand, the above-described embodiment is merely to explain an example of a preferred embodiment of the present invention, the scope of the present invention is not limited to such, and can be changed as appropriate within the scope of the same idea.

As described above, since the air supply and exhaust are made through one blower, the present invention significantly reduces the number of parts and noise, greatly reduces the production cost, and has a very useful effect of manufacturing a more compact product.

In addition, since the heat exchange is performed by the heat exchanging medium together with the blowing through one blower, the present invention has the effect of continuously providing external air exchanged for a long time in addition to smooth air supply and exhaust.

In addition, the present invention is because the mutual transfer of energy through the heat exchange medium is provided to the outside air of a temperature similar to the indoor air is exhausted. Therefore, since the change in the temperature of the room hardly occurs in addition to the ventilation effect, there is a very useful effect to significantly reduce the energy consumption due to the operation of the cooling / heating device according to the ventilation.

In addition, since the present invention removes foreign substances such as dust contained in the outside air by the heat exchange medium, there is a useful effect of providing a clean outside air to the room, the heat exchange medium to be accommodated through the separating plate coupling hole of the chamber case Since it is installed, the maintenance and management for cleaning the heat exchange medium has a very easy effect.
