The present invention is intended to reduce the temperature difference between the indoor and outdoor air during the intake and exhaust process without taking a sound pressure inside the ventilation ventilator to increase the saving effect of cooling and heating energy.

In order to realize the above technical idea, in the present application, a partition wall is installed inside a box-shaped case to form an exhaust path and an intake path respectively divided by the partition wall, and an exhaust fan and an intake fan are installed on the same axis of the motor. By installing a total heat exchanger at a location to reduce the temperature difference of the air during the exhaust and intake process, it is possible to provide a fan that can reduce the energy consumption.

The simplest way to purify contaminated air in an enclosed interior is to open a window and let in the outside air. This method is the most economical, but due to the cold at sub-zero temperatures, such as winter, the reality is that in the summer of 30 ℃ or more hot air is introduced into the room can not open the window for a long time. Especially in winter, when the ventilation is carried out, the indoor polluted air is discharged to the outside and very cold air flows in, and the indoor temperature warmed by heating drops sharply, and in summer, it can be described as contrary to the winter. have. If the temperature difference between the indoor and outdoor is considerably large, energy loss to heating in winter and cooling in summer is very large. In addition, although the air inlet and the outlet are installed in the large building, when the fan is operated in the enclosed indoor space of the apartment or the small door, the exhaust efficiency of the fan is increased as the negative pressure is applied because there is no air intake as much as the exhaust of the fan. In addition to falling power consumption and load of the exhaust fan is a lot of power consumption and reduce the life of the fan.

In order to solve this problem, Japanese Patent Laid-Open Publication No. 2004-096532 proposes a heat exchange fan similar to the present invention, and Japanese Patent Laid-Open Publication No. 2005-090929 proposes a ventilation system using geothermal air.

In Japanese Patent Laid-Open No. 2004-096532 proposed in the above patent, each of the first and second hot air fans is mounted on a box-shaped case, and each of two independent driving motors is mounted, and two heat exchangers are mounted. As two drive motors are installed on the case body independently, it is very inconvenient to replace and repair parts due to motor failure, and the displacement and suction amount can be different, so there is a possibility of negative pressure in the enclosed space. In addition, since the size of the fan is small as two motors and fans are installed in a case of a constant size, the intake and exhaust amount is small, and the purpose of ventilation cannot be achieved. According to the need to change the proposed patent has the disadvantage that the position should be changed according to the seasonal change.

In Japanese Patent Laid-Open Publication No. 2005-090929 proposed in the above patent, energy can be saved by using geothermal air, but the facility cost required for using geothermal heat is considerably consumed, and only the indoor air is discharged. Since the outside air itself is very likely to flow due to the indoor and outdoor temperature difference, the effect on energy saving is not so great, and the effect of the ventilation is insignificant, and the negative pressure may be applied.

Accordingly, the present invention is different from the method in which two hot air fans, a driving motor, and a heat exchanger are respectively installed in a box-shaped case of a predetermined size in the ventilator for purifying the air in the enclosed space. The exhaust path and the intake path which are distinguished by are formed, respectively, the exhaust fan and the intake fan are installed on the same axis of the motor, and the heat exchanger is installed at the exhaust and intake path positions to reduce the temperature difference of the air during the exhaust and intake process, The technical idea of maximizing the saving effect of cooling and heating energy is disclosed by reducing the temperature difference between indoor and outdoor air during the intake / exhaust process without taking negative pressure inside the room during ventilation. In addition, although the conventional thermoelectric exchanger changes its position according to winter and summer by the features of the thermoelectric exchanger, the ventilator of the present invention does not need to change the position of the heat exchanger or change the direction of the air, so that the user is more convenient. It is an object of the present invention to provide a fan that can greatly save energy during cooling and heating.

The exhaust fan is forcedly circulated by using a fan attached to the motor to purify the contaminated air inside the building, and can be broadly classified into kitchen, home, business, and industrial. Although somewhat different depending on the type and function, most fans are forced to circulate air inside the room by using one fan on the same shaft of the motor. Since there is no amount of air as much as the amount of air discharged during the forced discharge by the indoor air fan, the sound pressure is applied to the indoor space. As the electric resistance of the motor is increased by the negative pressure, the power consumption rate increases, the life of the motor is shortened, the efficiency of ventilation is reduced, and the fire of the motor by the resistance causes It can cause a loss. In particular, when the temperature difference between the indoors is large, such as summer and winter, as the outside air is introduced at the same time as the ventilation, the indoor temperature gets cold rapidly in the winter season, and it heats up rapidly in the summer season. This becomes large.

Looking at the technology related to the fan, Korean Patent Publication No. 2005-005202 proposes a method of reducing noise by offsetting the noise and vibration of the fan to the anti-phase wave in order to reduce the noise and vibration of the fan during operation of the fan, Korean Patent Publication No. 2003-0087676 proposes to operate the indoor air by sensing the temperature, pollution degree and humidity of each room sensor for the comfortable life of the residents. In addition, the size of the fan is increased or the rotation speed is increased so that the indoor air It is using a method to discharge.

As such, there is little or no way to save energy by preventing the negative pressure problem and the temperature difference between the air flowing in and the discharge by the only discharge method which must be basically solved when the air is purified by the fan.

Therefore, in the present invention, a partition wall is provided inside the box-shaped case to form an exhaust path and an intake path respectively separated by the partition wall, an exhaust fan and an intake fan are installed on the same axis of the motor, and the heat exchanger is positioned at the exhaust and intake path positions. By reducing the temperature difference of the air during the exhaust and intake process by installing, it is possible to significantly reduce the energy consumption, and to provide a problem solving by the negative pressure.

Means for implementing the above technical idea may be variously disclosed, the embodiments described below are only one embodiment for implementing the technical idea of the present application.

Applicant is an individual inventor, as a means for realizing the technical idea in the laboratory, by installing a partition wall inside the box-shaped case to form an exhaust path and an intake path separated by the partition wall, the exhaust fan and The intake fan is installed separately, and the heat exchanger is installed at the exhaust and intake paths to solve the negative pressure problem by the simple discharge method, and to reduce the temperature difference between the internal and external air during the exhaust and intake process. The invention was able to be completed by confirming that it can greatly protect.

The ventilator used in the present application does not impose any restriction such as for home use, office use, industrial use, etc., and it is irrelevant where the purpose of air purification and energy saving are accompanied.

Hereinafter, the means of an embodiment for implementing the present invention will be described in detail.

Exhaust and intake at the same time to prevent air pressure by the exhaust fan to prevent sound pressure in the indoor space, reduce noise and increase the effect of ventilation, increase the life of the fan motor, and minimize the temperature difference during the exhaust and intake process to reduce energy loss In order to minimize, a partition wall is installed inside the box-shaped case to form an exhaust path and an intake path respectively separated by the partition wall, and an exhaust fan and an intake fan are installed on the same axis of the motor, and a heat exchanger is installed at the exhaust and intake path positions. It is composed.

The case according to the present invention has a box shape, which is divided left and right by a partition wall 10 as shown in FIG. 1, and the indoor air intake path 3 and the outdoor air discharge path (3) on the left side of the drawing from the wall structure 1 ( 8) The indoor air exhaust path 4 and the outdoor air intake path 9 are formed on the right side, and the exhaust path inhales the contaminated indoor air through the indoor air intake port. The outdoor air is discharged to the outside, and the fresh outside air is sucked through the outdoor air inlet and discharged to the room through the outdoor air outlet, thereby effectively purifying the air contaminated in the room.

In order to simultaneously perform intake and exhaust on the same motor, two fan blades in the cells of the partition wall 10 must be differently positioned, and the indoor air intake or intake path 3 and the exhaust path 4 are It is advantageous to be located at the top of the wall structure 1 because the indoor air vent or, in general, the room temperature is high.

The air switch 2 may be implemented in a structure that is electrically opened and closed in connection with the operation of the motor, and may be implemented in a structure that is opened and closed by wind pressure, but in order to ensure accuracy, the air switch is opened at the same time as the operation of the motor. It is advantageous to carry out with.

The heat exchanger is advantageously made of the same type as the radiator of a car with high thermal conductivity and high specific surface area and metal materials such as silver copper, iron and stainless steel in order to improve the heat transfer efficiency between inflow and outflow air. In consideration of workability, it is advantageous to use a copper material. The heat exchanger can prevent heat loss through the continuous process of heating and condensation.Therefore, there are various problems to correct the position of the heat exchanger since the position of the heat exchanger must be changed according to the season with large temperature difference such as summer and winter. Can be derived. In order to reduce the inconvenience caused by the seasonal calibration of the heat exchanger, reverse rotation of the motor direction of the fan may have the same effect as calibrating the position of the heat exchanger. The path 3 becomes the indoor air exhaust path 4, and the outdoor air exhaust path 8 is changed to the outdoor air intake path 9, thereby reducing the temperature difference between the air during the exhaust and the intake process. It can be used conveniently with the same effect without the need to calibrate the thermoelectric exchanger.

Hereinafter, the present invention will be described in detail with reference to the following examples.

Example 1.

Then, the ventilator according to the present invention is installed at the top of the container box, and ventilated for exactly 15 minutes. In addition, the effect of the ventilation was examined by measuring the amount of formaldehyde not ventilated. Formaldehyde analysis was performed using KS K0611 acetylacetone method, the results are shown in Table 1.

Example 2.

After completely sealing the container box and igniting the five cigarettes inside the room to contaminate the cigarette smoke, the ventilation by the ventilator of the present invention for 10 minutes to examine the effect of the ventilation, the results are shown in Table 2. Ventilation was performed by five non-smokers by sensory method, and the average age of the sensory patients was 27.6 years.

Example 3

In order to test the effect of energy saving, the container box was completely enclosed and the oil heater was continuously operated in the room to keep the indoor temperature at an average of 26 ° C., and then measured the room temperature after operating the fan of the present invention for exactly 20 minutes. The results for this are shown in Table 3. At this time, the outdoor temperature was minus 5.6 ℃.

As a result of testing the ventilation efficiency with the formaldehyde target material, the ventilation efficiency was more than twice that of the conventionally used fan, and in case of the ventilation efficiency by the cigarette smoke, the odor of the power cigarette was not felt when the fan of the present invention was used. In the case of using a conventional ventilator, three were excellent, and two had normal results. In the aspect of the energy saving effect, the present invention with the heat exchange element is found that the energy saving effect is very large compared to the conventional fan because the temperature difference of the air flowing into the room is small.
