Description

Air conditioner with wet filter cleaning function

The present invention relates to an air conditioner having a wet filter cleaning function, and more particularly, a washing water spray connected to a rear surface or a rear surface and a front surface of an air filter installed in an air conditioner such as an air conditioner or a constant temperature humidifier and an air purifier. Selective or simultaneous installation of water and contaminant suction nozzles connected to the nozzle and vacuum pump enables automatic cleaning by spraying washing water at high pressure intermittently with various contaminants including dust attached to the air filter during operation of the air conditioner In addition, various contaminants remaining on the filter can be cleaned by spraying the washing water at high pressure in the rear part of the air filter as necessary, and by vacuum suction in the front part of the filter. In order to vacuum the moisture, including the substance This enables the user to clean the air without having to remove the air filter installed in various air conditioners, and greatly improves the quality and reliability of the product, thereby greatly increasing the satisfaction of the product. By adopting a method of removing contaminants remaining in the filter as well as moisture, the bacteria can be prevented from occurring in the filter in advance, thereby preventing the indoor air pollution and the damage caused by the bacteria.

In general, air conditioners such as thermo-hygrostats and air purifiers including air conditioners circulate indoor air of a building and inhale them together with air sucked from the outside to remove various foreign substances and pollutants including dust contained in the air. To make your life more comfortable.

The air conditioner is essentially provided with an air filter for filtering various foreign substances including dust contained in the air sucked from the outside to supply clean air to the room.

In the case of such an air filter, in order to maintain the performance of the air conditioner while preventing damage to the filter, the air conditioner must be cleaned or cleaned when it is used for a certain time.

However, in recent years, the air conditioner's air is used to protect the human body from air pollution factors caused by frequent yellow dust phenomenon, automobile exhaust gas, and scattering dust at construction sites, and to maintain air quality in living spaces and production facilities. Filter replacement and management costs are rapidly increasing.

As described above, air purifiers for purifying indoor air can be broadly classified into a dry air purifier and a wet air purifier.

In the case of dry air purifiers, air filters developed in various structures are installed in the purifiers on the air flow paths to collect dust contained in the air with the air filters. However, these dry air purifiers increase the amount of pollutants collected. While reducing the efficiency of filtering pollutants, due to the pollutants accumulated in the air filter there is a problem that the air pressure of the blower increases and the air volume of the air decreases.

In addition, if the air volume decreases, the temperature or humidity of the room changes, so the room temperature and humidity must be maintained by cooling or heating, which increases energy use. To prevent this, the manager frequently occupies the air filter. And there was a problem that the air filter had to be replaced.

In order to solve the above problems, the proposed wet air purifier can purify the air by removing and collecting the pollutants in the air with liquid, and the method of treating the wet clean air purifier is generally The cleaning solution is sprayed into the air to be purified to separate and adsorb contaminants of fine particles contained in the air.

In other words, when the indoor air and the outside air suctioned to circulate the indoor air are sucked into the air purifier and passed through the air filter installed in the air purifier, the cleaning device is sprayed with a spray device to filter the contaminants in the air while the air filters the air filter. It purifies the air by allowing it to pass through.

However, in order to solve the above problems, a wet air purifier has been developed to spray the water on the upper or lower side of the air filter to clean the air filter and at the same time purify the air, but the conventional wet air purifier has been developed. Most of the existing pollutants are used to filter out contaminants in the air together with the air filter by spraying water before or after the circulating air and the outside air pass through the air filter. The filter is often filtered out and the filter has to be replaced or cleaned frequently, and the management has to be continued.

In addition, the conventional wet air purifier as described above cleans contaminants in the air by using only one filter and one spraying device, so that the cleaning effect is weak and it is difficult to efficiently remove the contaminants. There is a vault, there is a problem that there is a possibility that bacteria are spread in the air that is eventually discharged into the room because various bacteria are inhabited.

The present invention has been made to solve such a conventional problem, and the water and contaminants connected to the washing water spray nozzle and the vacuum pump connected to the washing water pump on both the rear or rear and front of the removable air filter installed in the air conditioner Optionally or at the same time, the suction nozzle is installed to automatically clean the contaminants including dust attached to the air filter during operation of the air conditioner by spraying the washing water at high pressure, or at the rear of the air filter. By spraying the washing water to clean various pollutants, and in the front part of the filter, it is possible to remove the air filter of the air conditioner by vacuum suction method including the various contaminants remaining in the filter by vacuum suction method. Product can be cleaned cleanly and smoothly without using Not only can it greatly improve the quality and reliability, but it can also greatly increase the customer's satisfaction with the product. Especially, the filter can be removed by removing the contaminants and moisture remaining in the air filter by vacuum suction after high pressure injection of washing water.

When moving, the control unit 12 detects the restricted position according to the lifting and lowering, and transfers the bar-type washing water spray nozzle 5 or the water and pollutant suction nozzle 14 to the top or bottom of the control unit 12. Recognizing the lifting or lowering and responding to the control program stored in the It is possible to change the operation direction of the first sub-motor 7 or the second sub-motor 18 or to stop the driving thereof.

At this time, the washing water injection nozzle raising, lowering limit position detection sensor (9) (10) and suction nozzle raising, lowering limit position detection sensor (20, 21) can be presented a variety of elements, in the drawings of the present invention Up and down along the first guide rod 4 and the second guide rod 13 by installing a micro switch on the upper and lower sides of the first guide rod 4 and the second guide rod 13, respectively. When the cylindrical sliders 52 and 142 of the bar type washing water spray nozzle 5 and the water and pollutant suction nozzle 14 operate the operating lever of the micro switch, the control unit 12 respectively forms the bar type washing water spray nozzle 5. ) And the water and contaminant suction nozzles 14 are recognized as being raised or lowered by the restricted position.

However, the washing water spray nozzle raising and lowering position detection sensors 9 and 10 and the suction nozzle raising and lowering position detection sensors 20 and 21 are not limited to the above-described micro switch. Proximity switches that are turned on or off in response to the proximity of the 52 and 142 may be provided, and light reflecting plates may be provided to the cylindrical sliders 52 and 142 to provide the first and second guide rods 4 and 13. One side of the cylindrical sliders 52 and 142 of the bar-type washing water spray nozzle 5 and the water and pollutant suction nozzle 14 are installed by installing an optical sensor having light emitting and light receiving elements on one side of each of the upper and lower ends. The light emitted from the light emitting element of the optical sensor is moved to the light reflector attached to the cylindrical sliders 52 and 142 by raising or lowering to the uppermost limit position or the lowest limit position of the first and second guide rods 4 and 13. Reflected by the light-receiving elements of the optical sensor When it is detected, the control unit 12 may recognize that the bar-type washing water injection nozzle 5 and the water and pollutant suction nozzle 14 are raised or lowered by a limited position.

On the other hand, the cylindrical slider 52 of the bar-type washing water injection nozzle 5 which is lowered along the first guide rod 4 in response to the clockwise driving of the first sub-motor 7 as described above is the first guide rod ( When the lower limit position detection sensor 10 detects the lower limit position detection sensor 10 installed in the lower portion of the lower part and transmits it to the control unit 12, the control unit 12 serves as a sub stop. Since the driving direction of the motor 7 is driven counterclockwise, for example, in a counterclockwise direction, the bar-type washing water spray nozzle 5 is elevated along the first guide rod 4 again to the air filter 3. By spraying the washing water at a high pressure, various contaminants attached to the air filter are forcibly detached and continue to wash.

As described above, the cylindrical slider 52 of the bar-type washing water spray nozzle 5 which is elevated along the first guide rod 4 in response to the counterclockwise driving of the first sub-motor 7 is the first guide rod 4. When the detected signal is transmitted to the control unit 12 due to reaching the lift limit position detection sensor 9 installed above the control unit 12, the control unit 12 responds to the number of round trips stored in itself, for example. If it is stored in one round trip, the driving of the first sub-motor 7 is cut off, and if it is stored in two round trips, the driving direction is reversed again and the control to lower the bar type washing water spray nozzle 5 is continued. Done.

In addition, the switch signal input unit 11 performs a function of allowing a user to input an on / off signal according to whether the device is driven as described above, and includes a bar type washing water spray nozzle 5 as necessary. In order to provide a switch that allows the user to arbitrarily set the number of times of reciprocating and descending the water and the contaminant suction nozzle 14 to be described later.

In addition, the control unit 12 is to perform a specific control function for the present invention, including the overall control of the air conditioner according to the present invention, when the embodiment of the present invention is applied to the switch signal input unit 11 Is continuously monitored, and when a device " on " signal is input by an administrator or the like, the first sub-motor 7 is driven in response to a control program stored therein. When the rising or falling limit position detection signal is inputted from the washing water spray nozzle raising / lowering limit position detection sensor (9) 10 during the operation of the bar type washing water spray nozzle (5), the rising or falling direction is reversed or stopped. The function of controlling the first sub-motor 7 is performed.

At this time, the control unit 12 once or twice the clock and counterclockwise inversion of the first sub-motor 7 when the device "on" signal is input by the switch signal input unit 11 by a user's operation. The bar-type washing water spray nozzle 5 which is programmed to perform any one of the times and moves up and down along the first guide rod 4 or the second guide rod 13, or suction of water and pollutants described below. The nozzle 14 is controlled to move up and down by reciprocating once or twice while inhaling contaminants or injecting air.

On the other hand, while only the bar-type washing water spray nozzle (5) connected to the washing water pump (6) as described above, while spraying the washing water strongly toward the front portion from the back of the air filter (3) while moving up and down along the first guide rod (4) When cleaning to remove the various contaminants attached to the air filter (3), to the various contaminants attached to each gap of the filter (3) or attached to the front side of the air filter (3) There is a limit to the separation, which may not only effectively clean the air filter (3) itself, but also the water remaining in the air filter (3) after washing, there is a fear that bacteria, etc. breed in the air filter itself. Etc.

Therefore, in another embodiment of the present invention, as shown in Fig. 3 and 4, the second guide rod (in the state of being connected to the pair of second guide rod 13 and the vacuum pump 15 in the configuration of the embodiment described above ( 13) The power generated by the water and the pollutant suction nozzle 14 and the first sub-motor 7 which moves up and down and sucks the pollutants and water remaining in the air filter 3 and the first sub-motor 7 is polluted. The second power transmission means 16 is further provided to the substance suction nozzle 14, and the washing water is sprayed at a high pressure while the bar-type washing water spray nozzle 5 is moved up and down at the rear portion of the air filter 3. When washing the various contaminants attached to the air filter (3), the air filter (3) through the vacuum suction while moving up and down like the bar type washing water spray nozzle (5) in front of the air filter (3) Water, including various contaminants remaining in It was to make the suction force to be sent to the collecting wash water and pollutant house canteen (17).

At this time, the second guide rod 13 is installed vertically on both front sides of the air filter 3 to perform the guide function according to the rise and fall of the water and the pollutant suction nozzle (14).

In addition, the water and the pollutant suction nozzle 14 has a configuration in which the cylindrical slider 142 provided at both ends is provided to be moved up and down on the second guide rod 13, while the inlet 141 is the air It is installed close to the front part of the filter (3) to move up and down in response to the rotational direction of the first sub-motor (7) in response to the suction force of the vacuum pump 15 to the air filter (3) The water containing various residual contaminants adhered by forced suction was removed.

In addition, the vacuum pump 15 has a configuration connected between the water and the pollutant suction nozzle 14 and the wash water and the pollutant reservoir 17 through the flexible hose as described above, and the filter cleaning on switch by the user When the water and the pollutant suction nozzle 14 is moved up and down along the second guide rod 13 in response to the driving direction of the first sub-motor 7 under the control of the controller 12 due to the operation. Vacuum suction through water and contaminant suction nozzle 14 and flexible hose, including residual contaminants buried in the air filter 3 through suction operation, is collected in the wash water and pollutant reservoir 17 It will perform the function that makes it work.

On the other hand, the second power transmission means 16 is to transfer the power generated by the above-described first sub-motor (7) to the water and the pollutant suction nozzle 14, in the present invention and FIG. As shown in FIG. 4, second and third idler pulleys 161 and 162 are respectively disposed at upper and lower ends of one side of the second guide rod among the second guide rods 13, and the first sub-motor 7 of FIG. A second drive pulley 163 and a driven pulley 164 are respectively installed at the lower end of the shaft and the second guide rod 13, respectively, and the second drive pulley 163 of the sub-motor and the driven pulley of the second guide rod ( 164 and the second and third idler pulleys 162 arranged on the upper and lower ends of the guide rods 13, respectively, a chain or timing belts 165, 166 are installed, respectively, the water and contaminants The cylindrical slider 142 on one side of the suction nozzle 14 is connected between the second and third idle pulleys 162 through a connector 167. With the bar-type washing water spray nozzle 5 using the power generated from the first sub-motor 7 by adopting a configuration connected to the side closer to the air filter 3 among the installed chain or timing belt 165. Water and pollutant suction nozzles 14 were also allowed to operate up and down.

Therefore, as described above, the manager of the air conditioner recognizes the necessity of cleaning the air filter 3 and operates the filter cleaning on switch installed in the switch signal input unit 11, thereby causing the control unit 12 to perform the control. When the first sub-motor 7 is driven clockwise, for example, in the drawing of FIG. 3, the first drive pulley 82 of the first power transmission means 8 fixed to the axis of the sub-motor is connected to a chain or timing belt 83. Rotating the first idler pulley 81 in the clockwise direction through the bar washing water spray nozzle (5) is lowered along the first guide rod (4), and at the same time the second drive of the second power transmission means (16) The pulley 163 also rotates the driven pulley 164 and the third idler pulley 162 built in the bottom of the second guide rod 13 through the chain or the timing belt 165 in the clockwise direction so that the third pulley 162 rotates clockwise. Idle pulley 162 and chain and timing belt 166 A second idle bearings 161. The chukseol the upper end of the second guide rod 13 is connected, through also is rotated in the clockwise direction, thereby rotating the chain and a timing belt 166 in a clockwise direction.

In this case, the other end of the connector 167 having one end fixed to the cylindrical slider 142 on one side of the water and pollutant suction nozzle 14 is connected to a side far from the air filter 3 of the chain and the timing belt 166. Thus, the water and the contaminant suction nozzle 14 is also lowered along the second guide rod 13 in the same manner as the bar-type washing water spray nozzle 5 described above, in response to the suction operation of the vacuum pump 15. In the front part of), it drains water containing residual pollutants and forcibly detaches it.

However, in the second embodiment of the present invention, when the control unit 12 receives the device " on " signal once by the user, the first sub-motor 7 in the clockwise and counterclockwise directions as described above. The bar-type washing water spray nozzle 5 and water and contaminant suction which are programmed to perform the reversal one or two times to move up and down along the first or second guide rods 4 and 13. The nozzle 14 is moved up or down by reciprocating one or two times, but the washing water pump 6 is operated when the bar type washing water spray nozzle 5 descends along the first guide rod 4, The operation is controlled to be cut off, and the vacuum pump 15 is set to be controlled to be operated when the water and the pollutant suction nozzle 14 descends along the second guide rod 13 and to be operated when moving up and down.

Accordingly, the bar-type washing water spray nozzle 5 and the water and pollutant suction nozzle 14 correspond to the driving directions of the first sub-motor 7 along the first and second guide rods 4 and 13, respectively. Similarly, the first sub-motor 7 is driven clockwise, but the bar-type washing water spray nozzle 5 and the water and pollutant suction nozzle 14 are lowered due to the clockwise movement of the first sub-motor 7. ) Is not driven, only the washing water pump 6 is driven, so that the washing water is sprayed at a high pressure only in the bar type washing water injection nozzle 5 so that the air filter 3 is primarily washed by the washing water, and vice versa. Since the 7 is driven counterclockwise, the bar water washing nozzle 5 and the water and contaminant suction nozzle 14 are lifted, so that the washing water pump 6 is not driven but only the vacuum pump 15 is driven. The moisture and contaminant absorption Nozzle 14 only is previously washed by the washing water to be removed such as water, which faded to the remaining residual contamination of the air filter 3 and the filter itself is forcibly sucked into the secondary side of the vacuum pump 15.

Meanwhile, in another embodiment of the present invention, as shown in FIG. 5 and FIG. 6, the pair of second guide rods 13, the water and the pollutant suction nozzle 14, and the vacuum pump 15 may be used. ), The second sub-motor 18, the third power transmission means 19, and the suction nozzle raising and lowering position detection sensors 20 and 21 are further installed to prevent water and contamination with the bar-type washing water spray nozzle 5. Each of the material suction nozzles 14 uses separate sub-motors, i.e., the first and second sub-motors 7 and 18, respectively, to have different timings, and the first and second guide rods 4 and 13, respectively. As it moves up and down, it is possible to remove the washing and residual contaminants and water for the air filter (3).

In this case, the pair of second guide rods 13, the water and the pollutant suction nozzle 14, and the vacuum pump 15 have the same configuration and operation as the above-described second embodiment, and thus, further description thereof will be omitted. In addition, the suction nozzle lift, lower limit position detection sensor 20, 21 is also replaced with the description of the washing water injection nozzle lift, lower limit position detection sensor (9) (10).

In the above, the second sub-motor 18 functions to generate the power required for the water and the pollutant suction nozzle 14 to move up and down along the second guide rod 13, and the third power transmission means. 19 performs a function of transferring the power generated from the second sub-motor 18 to the water and the pollutant suction nozzle 14.

At this time, the third power transmission means 19 is installed separately from the first sub-motor (7) for generating the power required to move up and down the bar-type washing water injection nozzle 5, as shown in Figs. The fourth idler pulley 191 axially hung on the upper end of one of the second guide rods of the second guide rods 13 so as to transfer the power of the second sub-motor 18 only to the rising and lowering of the water and the contaminant suction nozzle 14. ) And a chain or timing belt 193 is installed between the third drive pulley 192 fixed to the shaft of the second sub-motor 18, and one side cylindrical slider (1) of the water and pollutant suction nozzle 14 142 has a configuration connected to the side closer to the air filter of the chain or timing belt 183 through the connector (194).

In addition, unlike the first and second embodiments described above, the controller 12 rotates the first sub-motor 7 clockwise and counterclockwise by a predetermined number of times when the device " on " signal is input by the user once. The bar-type washing water spray nozzle is moved up and down along the first guide rod 4 by operating the washing water pump 6 while moving the bar-type washing water spray nozzle 5 up and down along the first guide rod 4. (5) sprays the washing water from the rear part of the air filter 3 toward the front part, washes various contaminants adhering to the air filter 3, and then stops the driving of the first sub-motor 7 The vacuum pump 15 is operated by rotating the second sub-motor 18 clockwise and counterclockwise a predetermined number of times while moving the water and pollutant suction nozzle 14 along the first guide rod 4. Up and down along the second guide rod (13) After being removed by vacuum suction to force the contaminants and water remaining on the air filter 3 through the water and contaminant suction nozzle 14 is halted.

Thus, in the air conditioner of the present invention, when the user wants to clean the air filter 3, the air filter itself is not separated from the inside of the main body of the air conditioner. The washing water is sprayed at high pressure from the bar type washing water spray nozzle installed at the rear of the air filter to move up and down, so that various contaminants attached to the air filter are automatically cleaned, or at the rear of the air filter, the washing water is By spraying, various kinds of pollutants are first washed and then air is removed from the air filter front by removing water, including various pollutants remaining in the filter through the vacuum suction method using water and pollutant suction nozzle and vacuum pump. Clean and smooth cleaning without removing the air filter of the conditioner Not only can it greatly improve the quality and reliability of the product, but also greatly increase the customer's satisfaction with the product. Especially, it can remove the contaminants remaining in the air filter as well as moisture through vacuum suction after high pressure injection of washing water. By making it possible to prevent bacterial habitation in the filter in advance, it is possible to prevent indoor air pollution and its damage caused by bacteria in advance, and contribute to the health of consumers.
