The present invention relates to a ventilator equipped with an air cleaning function, and more particularly, to reduce the space constraints required for the installation of the ventilator, the ventilation provided with an air cleaning function that the user can select the air cleaning function Relates to a device.

In general homes and offices, air-conditioning and heating devices are installed to perform indoor cooling and heating according to the change of seasons. In these cooling and heating devices, air-conditioning that performs cooling and heating by cooling and heating indoor air , Boiler, etc.

Indoors such as homes and offices with air conditioning and heating systems are kept closed to improve cooling and heating efficiency, and the sealed indoor spaces have increased air pollution after a certain period of time. Odor occurs or foreign matter such as dust becomes suspended. Therefore, the indoor air is ventilated every certain time to remove such odors and dust indoors. Ventilation for exhausting contaminated indoor air to the outside quickly while maintaining the indoor temperature, and for supplying fresh outdoor air to the room. The device is used.

Conventional ventilators include a first air supply chamber into which outdoor air is introduced, a second air supply chamber to supply outdoor air to the room via the first air supply chamber, a first exhaust chamber into which indoor air is introduced, and the first exhaust air Heat exchange is performed between the second exhaust chamber for discharging indoor air through the chamber to the outside, the indoor air flowing into the second exhaust chamber from the first exhaust chamber, and the outdoor air flowing into the second exhaust chamber from the first air chamber. An electric heat exchanger, an air blower for forcibly sucking the outdoor air into the room, and an air blower for forcibly discharging the indoor air to the outside are provided.

Recently, a ventilator having an air cleaning function for filtering foreign substances contained in the indoor air while circulating the indoor air has been developed.

(A reference numeral 103a), by directly connecting the first exhaust chamber and the second supply chamber in the air cleaning mode, the indoor air introduced into the first exhaust chamber directly back through the second supply chamber without going through the heat exchanger It is configured to be circulated.

According to this structure, however, a circulation damper and a filter (reference numeral 109) must be provided between the first exhaust chamber and the second exhaust chamber, and the exhaust duct and the supply duct must be connected to the first exhaust chamber and the second supply chamber, respectively. Therefore, there is a problem that the length of the ventilator is longer in the direction in which the exhaust duct and the air supply duct are connected.

In addition, there is provided a filter for filtering indoor air in the air cleaning mode, if there is a problem that must be further provided to filter the indoor air more clean.

In addition, since the circulation damper and filter for implementing the air cleaning mode cannot be detached from the ventilation device, the ventilation device with the air cleaning function and the ventilation device without the air cleaning function can be selected as the customer's option. There is no problem.

On the other hand, the ventilator is provided with a filter for filtering the foreign matter contained in the air, if the ventilator is used for a certain time, it is necessary to clean or replace the filter periodically because the foreign matter is accumulated in the filter.

In general, prefilters are replaced at least once every 2-3 months, and HEPA filters are replaced every 6 months to 1 year. Prefilters that filter out relatively large dust are blocked before HEPA filters that filter out small dust, so the prefilter has a shorter cleaning cycle than hepa filters.

As described above, the inspection time varies depending on the type of filter, and there is an inconvenience in that the filter must be cleaned or replaced at least once every two months. There is an inconvenience in not using the ventilation device during the implementation of the time.

It is configured to filter foreign matter, there is an effect that can be used without replacing the filter for a long time.

However, in such a configuration, since the dust accumulates inside the product when used for a long time, the contamination inside the product becomes serious, and due to the filter connected through the roller, indoor air and outdoor air are mixed to deteriorate the function of the ventilator. There is a problem.

The filter cleaning apparatus of the ventilation system disclosed in the above Patent No. 10-0894362, because the filter for cleaning the filter should be further provided with a guide rail, a rotating shaft, a brush, a screw shaft, the first and second drive motors, The structure is complicated, and the dust accumulated in the product by the operation of the filter cleaning device is inconvenient to clean separately.

The self-cleaning device of the ventilation air supply duct disclosed in Korean Utility Model Registration No. 20-0358104 is provided with an intake device for removing dust accumulated in the air supply pipe, but in this configuration, the dust in the air supply pipe can be removed.

The rotary blades 712-1 and 713-1 remain closed.

Since the anti-wind damper can simplify the structure and reduce the cost of components compared to the electric damper, the first and second circulation dampers (710 and 720) can be reduced in cost compared to the case of the electric damper.

Hereinafter, with reference to Figure 6, the configuration of the ventilation device 1 and the operation in the filter cleaning mode according to another embodiment of the present invention will be described, the same reference numerals are given to the same members as the above embodiments, Overlapping descriptions are omitted.

Ventilation apparatus 1 according to the present embodiment, the first exhaust damper 120 for opening and closing the indoor air inlet 110 provided in the indoor side of the first exhaust chamber 100 and the second exhaust chamber 200 The second exhaust damper 220 for opening and closing the indoor air outlet 210 provided on the outdoor side of the) and the first opening and closing the outdoor air inlet 310 provided on the outdoor side of the first air supply chamber 300 The air supply damper 320, and the second air supply damper 420 for opening and closing the outdoor air outlet 410 provided in the indoor side of the second air supply chamber 400.

In the filter cleaning mode, the second air damper 420 and the second exhaust damper 220 are opened, and the first exhaust damper 120 and the first air supply damper 320 are closed. In addition, the air supply blower 430 is not operated, and only the exhaust blower 230 is operated.

Therefore, in the filter cleaning mode, the indoor air flows into the second air supply chamber 400 by the operation of the exhaust blower 230 and passes through the heat exchanger 500 and the circulation passage 700 and the filter ( After back washing 510 and 740, the first exhaust chamber 100 is discharged to the outside via the first heat exchanger 500 and the second exhaust chamber 200.

Here, the backwashing of the filters 510 and 740 may include one side of the filter 510 facing the first air supply chamber 300 and one side of the filter 740 provided in the circulation passage 700 (left side in FIG. 6). If foreign matter such as dust is attached to the surface, air is flowed in the direction from one side of the filter (510,740) toward one side to blow off the foreign matter attached to one side of the filter (510,740) to separate and remove Means that.

As described above, since the foreign matter attached to the filters 510 and 740 can be removed only by the operation of the exhaust blower 230, the cleaning of the filters 510 and 740 can be easily and automatically performed without disassembling the ventilation device 1. have.

In addition, in the present invention, since it is possible to backwash the filters 510 and 740 while using the existing equipment of the ventilator 1 without additional configuration for backwashing the filters 510 and 740, the backwashing without increasing the manufacturing cost and volume is possible. It is possible to implement a ventilator (1) capable of cleaning.

On the other hand, the filter cleaning mode can be configured to be operated when the rotation speed of the air supply blower 430 is higher than a predetermined rotation speed compared with the initially set rotation speed. That is, when foreign matter accumulates in the filters 510 and 740 and the air gap of the filter medium provided in the filters 510 and 740 is clogged or narrowed, the number of rotations of the air supply blower 430 may be increased in order to satisfy a constant air supply capacity in the air supply blower 430. It will increase automatically. As such, when the rotation speed of the air supply blower 430 is increased by more than a predetermined rotation speed in comparison with the initially set rotation speed, the controller determines that the cleaning of the filters 510 and 740 is necessary, so that the filter cleaning mode is automatically performed. Control.

In another embodiment, when the air supply blower 430 is operated for a predetermined time, the filter cleaning mode may be automatically executed. That is, when the ventilator 1 is operated for a predetermined time other than the filter cleaning mode, for example, the ventilation mode or the air cleaning mode, the filter 510 and 740 accumulate foreign substances. After the air supply blower 430 is operated for a predetermined time, the filter cleaning mode may be automatically executed for a predetermined time so that the filters 510 and 740 may be automatically cleaned at regular intervals.

As such, when the rotation speed of the air supply blower 430 is higher than a predetermined rotation speed or when the air supply blower 430 is operated for a set time, the filter cleaning mode is automatically executed. In addition, since the filters 510 and 740 can be automatically cleaned without a user's manual operation, the convenience of operating the ventilator 1 is improved.

As described above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above-described embodiments, and various modifications are made within the scope of the claims and the detailed description of the invention and the accompanying drawings.
