Description

The device that support the replacement process of the mechanical filter for the air purifier

The present invention relates to a device that supports the replacement procedure of a mechanical filter for an air purifier, and more particularly, the determination of the mechanical filter replacement time by the filter replacement management unit is simply, 'If the use time of the air purifier increases, the mechanical filter It is not an assumption that the accumulated amount of pollution will also increase (i.e., a time-proportional filter pollution estimation method), but a very objective value that can immediately reflect the actual accumulated dust amount of the mechanical filter, that is, ‘the Optimal rational standard that flexibly reflects the increasing fan torque value and PWM duty value', or 'optimum that flexibly reflects the electrostatic force and clean air supply rate of the mechanical filter, which gradually decreases as the amount of accumulated dust in the mechanical filter increases By inducing it to be done according to the 'reasonable standards of It relates to a replacement support device for a mechanical filter for an air purifier that can effectively avoid serious problems, unnecessary waste of resources, unnecessary waste treatment cost, unnecessary environmental pollution, etc.)

Recently, as the demand for air purifiers has rapidly increased, various technologies related to replacement of filters for air purifiers have been widely developed/distributed.

For example, Republic of Korea Patent No. 10-819077 (Name: Filter replacement time indication method of an air purifier), Korean Patent Laid-Open No. 10-2010-89605 (Name: Method of calculating filter replacement time of an air purifier), Republic of Korea Patent Laid-Open No. 10-2010-4069 (Name: System and method for determining when to replace an air purifier filter using motor speed measurement), Republic of Korea Patent Publication No. 10-2013-74486 (Name: Display of air purifier and filter lifespan thereof) Method) and Korean Patent Application Laid-Open No. 10-2013-47707 (Name: Control method for tracking filter life in an air treatment system), examples of various technologies related to the replacement of a conventional filter for an air purifier are described in more detail. has been disclosed.

On the other hand, under this conventional system, the air purifier has a main body 1 having an air inlet and an air outlet, a mechanical filter 2 that purifies the air sucked into the main body 1, and air containing dust through the inlet. A fan driving motor 4 for driving the fan 3 so as to be sucked in, a motor driving unit 5 for applying a driving pulse to the fan driving motor 4 to operate the corresponding fan driving motor 4, the motor The purifier control unit 6 that generally controls each component inside the main body 1 including the drive unit 5, the filter replacement management unit 8 controlled by the purifier control unit 6, etc. are closely A combined configuration will be taken.

At this time, the filter replacement management unit 8 determines the replacement time of the mechanical filter 2 while communicating with the purifier accessory unit 7 such as various sensors and various timers, and displays the result on the display unit 9 By outputting through the air purifier, the user of the air purifier supports to stably replace the mechanical filter 2 that has exhausted its function.

However, under this conventional system, the filter replacement management unit 8 simply assumes that 'when the use time of the air purifier increases, the amount of pollution (eg, dust) accumulated in the mechanical filter 2 also increases'. (that is, according to the 'time proportional filter pollution estimation method'), since the replacement time of the mechanical filter 2 is recklessly determined, the actual accumulated dust amount (or accumulated pollution amount) of the mechanical filter 2 is not so It is not large, and although the use of the mechanical filter 2 is still normally possible, a 'message urging the replacement of the mechanical filter 2' is output through the display unit 9, which causes a serious problem.

Of course, under these problems, the general air purifier user, who cannot accurately recognize the situation, according to the 'message urging the replacement of the mechanical filter (2),' despite the fact that normal use of the mechanical filter 2 is still possible, The filter 2 has to be replaced unnecessarily and excessively.

Naturally, under the reckless over-replacement of the mechanical filter 2 described above, the air purifier user cannot avoid serious damage in which the overall cost of using the air purifier increases significantly more than necessary, and socially, 'unnecessary resource waste problem' ', 'unnecessary waste treatment cost problem', 'unnecessary environmental pollution problem', etc. will be unavoidable.

Hereinafter, an apparatus for supporting replacement of a mechanical filter for an air purifier according to each embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

As shown in Fig. 2, under the system of the present invention, the air purifier has a main body 11 having an air inlet and an air outlet, a mechanical filter 12 for purifying the air sucked into the main body 11, and the inlet through A fan driving motor 14 for driving the fan 13 so that air containing dust can be sucked in, and a motor driving unit for applying a driving pulse to the fan driving motor 14 to operate the corresponding fan driving motor 14 (15), a purifier control unit 16 that generally controls each component inside the main body 11 including the motor driving unit 15, a filter replacement management unit controlled by the purifier control unit 16 ( 18), etc., will take a closely combined configuration.

Even at this time, the filter replacement management unit 18 determines the replacement time of the mechanical filter 12 while communicating with the purifier accessory unit 17 such as various sensors and various timers, and displays the result on the display unit 19 By outputting through , the air purifier user side supports to stably replace the mechanical filter 12 that has exhausted its function.

Of course, even under this system of the present invention, unless special measures are taken, the filter replacement management unit 8 simply states, 'If the use time of the air purifier increases, the amount of pollution accumulated in the mechanical filter 12 (for example, . Although the actual accumulated dust amount (or accumulated contamination amount) of It causes serious problems in outputting through

Under such a sensitive situation, as shown in FIG. 2, in the present invention, under the communication infrastructure such as the purifier control unit 16, the motor driving unit 15, the filter replacement management unit 18, the mechanical filter replacement unique to the present invention A measure of additionally installing the support device 20 is taken. In this case, the mechanical filter replacement support device 20 according to the present invention may have a structure in which the purifier control unit 16 or the filter replacement management unit 18 is subordinately installed in the program block according to circumstances.

At this time, as shown in FIG. 3, the mechanical filter replacement support device 20 for an air purifier according to the present invention uses the interface module 21 as a medium, the purifier control unit 16, the motor driving unit 15, Filter replacement management unit 18, operation information storage module 22 that communicates with display unit 19, etc., PWM duty value receiving module 23, mechanical filter replacement support module 24, process information storage module 25 , the mechanical filter immediate replacement support module 27, the mechanical filter replacement support situation upload module 28, etc. take a closely combined configuration.

In this case, on the operation information storage module 22 side, various operation information, for example, registration information of the purifier control unit 16, registration information of the motor driving unit 15, registration information of the filter replacement management unit 18, Registration information of the display unit 19, registration information of the online network 60, registration information of the air purifier management cloud server 30, source information for forming/maintaining a communication session, and a source for processing each computer module By stably storing/managing information, etc., a series of mechanical filter replacement support services according to the present invention play a role of assisting to proceed normally without any particular problems.

In addition, the process information storage module 25 stores/manages the mechanical filter contamination criterion record table 26, including various information generated by each computer module, to support a series of mechanical filter replacement according to the present invention It plays a supporting role so that the service can proceed normally without any problems.

At this time, on the side of the mechanical filter contamination determination criterion recording table 26 , a PWM duty value applied for controlling the fan 13 and a fan torque value corresponding to the PWM duty value, and the fan The accumulated dust amount corresponding to the torque value is recorded/stored.

For reference, the present applicant, through a number of repeated experiments, 'when the amount of accumulated dust on the mechanical filter 12 side increases, and the degree of contamination of the corresponding mechanical filter 12 increases, correspondingly, the fan 13 has A higher torque is applied, and as such, if the torque applied to the fan 13 increases, the PWM duty value output/applied to the fan driving motor 14 for controlling the fan 13 also increases. came to check.

In <Table 1> below, an example of an experiment conducted by the present applicant on a HEPA filter is presented.

accumulated dust 4th
accumulated dust fan torque 43.324 46.167 47.336 52.365 59.831 PWM 3.55 3.591 3.599 3.605 3.614

Based on this fact, the present applicant writes/stores the fan torque value corresponding to the PWM duty value and the accumulated dust amount corresponding to the fan torque value in the 'mechanical filter contamination criterion record table 26, When a change occurs, if the change occurrence status is notified to the filter replacement management unit 18, the determination of the mechanical filter replacement time by the filter replacement management unit 18 is simply, if the use time of the air purifier increases, It is not an assumption that the amount of pollution accumulated in the mechanical filter will also increase (that is, a time-proportional filter pollution estimation method), but a very objective value that can immediately reflect the actual accumulated dust amount of the mechanical filter 12 , that is, an increase in the accumulated dust amount The technical point of 'will be able to be achieved according to the optimal and reasonable standard that is flexibly reflected in the fan torque value and PWM duty value, which gradually increases according to the

On the other hand, under the above-described infrastructure, the PWM duty value receiving module 23 side communicates with the purifier control unit 16, the motor driving unit 15, etc. through the interface module 21, and the fan 13 It plays the role of receiving the output/applied PWM duty value for the control of

In this way, when the output/applied PWM duty value for control of the fan 13 is received, the mechanical filter replacement support module 24 communicates with the PWM duty value receiving module 23 and reads the PWM duty value. The procedure will proceed (see FIG. 3).

When the PWM duty value is read through the above-described procedure, the mechanical filter replacement support module 24 communicates with the mechanical filter contamination determination standard record table 26 and proceeds with a series of information extraction routines to complete the reading A procedure for extracting the fan torque value and the accumulated dust amount corresponding to the PWM duty value is performed (see FIG. 3 ).

In this way, when the extraction of the fan torque value and the accumulated dust amount corresponding to the PWM duty value is completed, the mechanical filter replacement support module 24 communicates with the filter replacement management unit 18 through the interface module 21, A procedure of transmitting the extracted fan torque value, the accumulated dust amount, and the PWM duty value to the filter replacement management unit 18 is performed.

Of course, when the fan torque value, the accumulated dust amount, and the PWM duty value are transmitted through the above procedure, the filter replacement management unit 18 determines the replacement time of the mechanical filter 12 in the process of determining the replacement time of the mechanical filter 12, the fan torque value and the accumulated dust amount And, it is possible to reflect the PWM duty value very effectively (that is, when determining when to replace the mechanical filter, simply assume that if the use time of the air purifier increases, the amount of pollution accumulated in the mechanical filter also increases - that is, time It is not a proportional filter pollution estimation method, but a very objective value that can immediately reflect the actual accumulated dust amount of the mechanical filter 12, that is, the fan torque value and the PWM duty value that gradually increase as the accumulated dust amount increases. ), and eventually, on the air purifier side, 'the actual accumulated dust amount (or accumulated pollution amount) of the mechanical filter 12 is not so large, so the use of the mechanical filter 12 is not Although it is still normally possible, the message urging the replacement of the mechanical filter 12 is outputted through the display unit 19 , which does not cause a serious problem at all.

As described above, in the present invention, under the communication infrastructure such as the purifier control unit, the motor driving unit, and the filter replacement management unit, <PWM duty value applied to control the fan and the fan corresponding to the PWM duty value A computer module capable of storing and processing the torque value and the accumulated dust amount corresponding to the fan torque value>, which can receive the PWM duty value applied to control the fan while communicating with the purifier control unit or motor driving unit Computing module>, <After reading the received PWM duty value, extract the fan torque value and the accumulated dust amount corresponding to the read PWM duty value, and manage the filter replacement of the extracted fan torque value and the accumulated dust amount and the PWM duty value A computer module that can be transmitted to the unit and induce the fan torque value, accumulated dust amount, and PWM duty value to be reflected in the process of determining when to replace the mechanical filter by the filter replacement management unit>, etc. Therefore, under the implementation environment of the present invention, the determination of the mechanical filter replacement time by the filter replacement management unit is simply, 'As the usage time of the air purifier increases, the amount of contamination accumulated in the mechanical filter also increases (that is, the time Rather than 'proportional filter pollution estimation method)', a very objective value that can immediately reflect the actual accumulated dust amount of the mechanical filter, that is, 'the fan torque value and PWM duty value that gradually increase as the accumulated dust amount increases' is flexible. In the end, the air purifier user as well as all members of society suffer from various problems caused by the reckless and excessive disposal of the mechanical filter (for example, the cost of using the air purifier is significantly higher than necessary). Increasing serious problems, unnecessary resource waste, unnecessary waste treatment costs, unnecessary environmental pollution, etc.) can be effectively avoided without any special problems.

On the other hand, as shown in Figures 2 and 3, in the device 20 of the present invention, in addition to each of the preceding computer modules, a mechanical filter immediate replacement induction module 27, a mechanical filter replacement support situation upload module ( 28) are additionally placed.

At this time. The mechanical filter immediate replacement induction module 27 side communicates with the PWM duty value receiving module 23 and the mechanical filter replacement support module 24, and proceeds with a series of information reading routines to read the PWM duty value will proceed with

In this way, when the PWM duty value is read, the mechanical filter immediate replacement induction module 27 communicates with the mechanical filter contamination judgment standard record table 26 and proceeds with a series of information comparison routines, and the fan torque described therein The value and the accumulated dust amount are compared with the PWM duty value, and through this, it is determined whether the fan torque value and the accumulated dust amount corresponding to the PWM duty value correspond to the maximum fan torque value and the maximum accumulated dust amount.

At this time, if it is determined that the fan torque value and the accumulated dust amount corresponding to the PWM duty value correspond to the maximum fan torque value and the maximum accumulated dust amount, the mechanical filter immediate replacement induction module 27 proceeds with a series of information generation routines, A process of generating a mechanical filter immediate replacement prompt message for inducing immediate replacement of the mechanical filter and outputting the generated mechanical filter immediate replacement prompt message through the display unit 19 proceeds.

Of course, under the function of the mechanical filter immediate replacement induction module 27 side, the air purifier user side very quickly recognizes that the mechanical filter 12 is in a serious situation, and takes corresponding measures (eg, filter replacement measures). can be taken quickly, and in the end, it is possible to effectively enjoy the advantage of greatly increasing the overall air purifier use efficiency.

On the other hand, on the side of the mechanical filter replacement support status upload module 28 that operates in conjunction with each of the computer modules, the filter replacement management unit 18, the mechanical filter replacement support module 24, or the mechanical filter replacement induction module 27 ) while communicating with others, a series of information receiving routines are carried out, and the mechanical filter replacement support status information reflecting the replacement support status of the mechanical filter 12 (eg, replacement support message details, replacement support message number/transmission date and time, filter The procedure for receiving the replacement status, filter replacement date, etc.) will proceed.

In this case, the dust inflow per minute calculation module 73 communicates with the operation information storage module 72 , the purifier control unit 16 , the purifier accessory unit 17 , the process information storage module 75 , and the like. Values required for calculation, that is, building dust particle penetration rate, external dust concentration, outside air inflow ratio, spatial natural dust deposition rate, building internal air outflow ratio, dust concentration, cleanable area of the air purifier, initial air volume at the time of shipment , the amount of air compared to the PWM output of the air purifier, and the height of the cleanliness of the building are obtained.
