[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for an air purifier.

[0002]

2. Description of the Related Art In recent years, air purifiers for purifying indoor air have been developed by removing deodorizing, collecting dust, and removing the smoke, smell, pollen, etc. of tobacco contained in indoor air with high precision. , Has been commonly used.

For example, as shown in FIG. 1, a fan 2 and an air purifying filter 3 are built in a main body casing 1 as shown in FIG. It is well known that indoor air W is configured to pass through the filter 3 to be cleaned, and then blown into the room from the air outlet 5. Reference numeral 6 denotes a cover plate that covers the front surface of the main body casing 1.

[0004]

By the way, recently,
Such an air purifier has a plurality of fan drive control sequences (air purification control systems) that can perform deodorization and dust collection particularly effectively according to the type of air contamination such as tobacco mode and pollen mode, respectively. ) Is being studied so that such a dedicated mode can be arbitrarily selected and set by a mode setting switch.

However, even if such a configuration is adopted, the original air cleaning effect can be effectively realized if the selected and set control mode does not correspond to the actual state of air contamination or the type of contamination. The problem that cannot be done arises.

It has also been considered that a predetermined fragrance is further added to the air after the above-described air purification to form a refreshing indoor air-conditioning environment with high sensibility.

However, in this case, simply providing an air freshener at the air outlet is not sufficient to clean the air, for example, when the room is full of tobacco smoke. Even if a scent is added in the state of, there is a problem that the effect of improving the exhilarating feeling by the original scent addition is low only with a slight deodorizing effect, and the user can hardly feel a good scent. .

It is characterized by realizing such two types of manual and automatic fan control systems.

Next, the control contents of the manual control system of the system will be described in detail with reference to the flowchart of FIG.

[0053] That is, first in step S _1, determines whether the current selection setting mode is "tobacco mode".

As a result, when the result is YES, the process proceeds to step S ₂ , in which the fan 2 is driven at the maximum rotation speed such that the fan air volume is at the strong level which is the maximum capacity, and sufficient convection is formed in the entire room air. In addition, the entire indoor air is purified as efficiently as possible, and the odor of tobacco is deodorized. Operation with the fan air flow strong level, so inevitably noise is high, the entire room air convection was formed, and the first operation timer T ₁ set in step S ₃ that can be cleaned without looking mud minimum required set time T within ₁ continues only until the elapsed is determined in step S _4.

When it is determined in step S ₄ that the set time T ₁ has elapsed, the process proceeds to step S ₅ , where the noise is not high, and sufficient air cleaning ability can be maintained. Step S for operation at medium fan airflow level
It is second to execution operation timer T ₂ of the inner set time T ₂ was set at _6. As a result, the cleaning and deodorizing action by the stable absorption of cigarette smoke is maintained in a relatively quiet state with sufficient cleaning ability with gentle convection throughout the room.

[0056] When the further set time t ₂ has elapsed at step S ₇ in the second operating timer T ₂ is determined, in turn proceeds to step S _8, S _9, set to a weak level the fan air volume third operational timer T ₃ by within set operating time T ₃ and is operated at light winds. In this state, almost all of the smoke generated during smoking is smoothly suction-purified,
There is no danger of filling the room.

[0057] When elapse of the set time T ₃ of the third operational timer T ₃ in step S ₁₀ is determined, once the fan is turned OFF at step S ₁₁ in response to smoking completion such, the OFF state is continued for a fourth operational timer T within ₄ OFF setting time T _4, which is set in step S _12. Then, it is determined whether or not the OFF setting time T ₄ has elapsed in step S _13, when the result is YES, on further confirmed whether OFF operation of the air purifier itself by users (Power OFF) is made If NO in step S _8,
Proceeding to the following operation, the intermittent operation in the state of the low fan air flow level is executed to continue the cleaning of the remaining cigarette smoke and the deodorization of the odor, and to turn on and off in the extremely quiet breeze state.

As a result, a stable air cleaning state can always be maintained with low power consumption.

Next, the contents of tobacco mode of the air cleaner control system according to the automatic system using the output of the sensor DS ₁ of the system with reference to the flowchart of FIG. 9 will be described in detail.

[0060] That is, first in step S _1, the same current is selected setting mode determines whether the "tobacco mode".

As a result, when the result is YES, the process proceeds to step S ₂ , in which the fan 2 is driven at the maximum rotation speed such that the fan air volume is at the maximum level, which is the maximum capacity, to form a sufficient convection in the indoor air. Purify the entire room air as efficiently as possible and deodorize tobacco odors. Operation with the fan air flow strong level, so inevitably noise is high, the convection is formed in the whole room air, the first required operation timer T ₁ set in step S ₃ that can be cleaned without looking mud minimum preset time T within ₁ continues only until the elapsed is determined in step S _4.

[0062] When the time course of T ₁ in step S ₄ is determined, the process proceeds to step S ₅ to the next, without high noise, yet fan air volume that can maintain a sufficient air cleaning ability operated to perform a second operation within the set time T ₂ of the timer T ₂ set in step S ₆ at medium level. As a result, in a state of being relatively quiet and having a sufficient cleaning ability capable of forming convection for the entire room, a stable cigarette smoke cleaning and deodorizing action is maintained.

[0063] Then, further when the second operation elapsed timer T ₂ of the set time t ₂ is determined at step S _7, followed by the detection output V of the sensor DS ₁ proceeds to step S ₈
Enter the o, subsequent step S ₉ detection output Vo is the tobacco mode corresponding to that has been set predetermined set reference value Vs or more, a ie contamination degree of cigarette smoke, odor degree setting level or higher Is determined.

[0064] Then, as a result, when it is determined YES, then the third operational timer T ₃ by the setting operation time T within ₃ to set the fan air volume proceeds to step S ₁₀ to the weak level, the air volume Operate in low breeze conditions. Thus, most of the smoke generated during smoking is suctioned and cleaned more smoothly.

[0065] Then, when the lapse of the set operating time T ₃ of the third operational timer T ₃ in step S ₁₂ is determined, once OFF the fan at step S ₁₃ in response to smoking completion etc.
To be continued fourth operational timer T within ₄ OFF setting time T _4, which is set to the OFF state at step S _14. Then, it is determined whether the OFF setting time T ₄ has elapsed in step S _15, when the result is YES, further air purifier itself OFF operation by the user in step S ₁₆ (Power OF
Cleaning of smoke and the remaining running intermittent operation of a fan Kazeryoujaku level state proceeds to the aforementioned Step S ₈ following operation again when the NO on the F) confirms whether been made Continues deodorization of odors and performs ON / OFF operation in extremely quiet breeze.

As a result, it is possible to always maintain a stable air cleaning state with low power consumption.

[0067] On the other hand, when the cleaning of the tobacco mode detection output Vo of the sensor DS ₁ in step S ₉ is determined to be lower than the set reference value Vs is completed, the process proceeds to step S ₁₇ Turn fan 2 off.

As a result, in this configuration, unlike the case of the manual system, when air cleaning and deodorization are completed,
Completion of the cleaning and deodorizing is automatically determined based on the output of the sensor, and the operation of the air purifier can be automatically stopped.

(Embodiment 3) FIGS. 10 and 11 show Embodiment 3 of the present invention configured on the premise of the structure of the air purifier of FIGS. 1 to 4 and the configuration of the air cleaning system of FIG. 5 shows details of manual and automatic air cleaning control in the pollen mode according to the first embodiment.

That is, in the air purifying control system according to the present embodiment, as shown in FIG.
With respect to the mode determination unit 18, the contamination level setting unit 19,
A pollution level determination unit 20, a fan control unit 21, a timer setting unit 35, a timer unit 29, and the like are provided. In particular, when the pollen mode (3) is selected by the user, the pollen mode is selected as much as possible. It is characterized by realizing a manual and automatic fan operation control system capable of collecting pollen and removing pollen efficiently with low noise.

First, the contents of the manual fan control of the system will be described in detail with reference to the flowchart of FIG.

[0072] That is, first in step S _1, determines whether the current selection setting mode is the "pollen mode".

As a result, when the result is YES, the process proceeds to step S ₂ , in which the fan 2 is driven at the maximum rotation speed such that the fan air volume is at the maximum level, which is the maximum capacity, and sufficient convection is formed in the air in the entire room. Then, heavy pollen distributed on the floor surface is soared into the air to purify the indoor air as efficiently as possible and to absorb the pollen. Since the operation at the high fan airflow level inevitably generates high noise, a step of forming convection in the air in the entire room as described above, so that pollen on the floor surface can be swept up and cleaned sufficiently without dirt. S ₃
In the set first operating timer T ₁ of the minimum required set time T within ₁ continues only until the elapsed is determined in step S _4.

[0074] Then, when the lapse of the set time T ₁ at step S ₄ is determined, fans proceeds to step S ₅ to the next, without high noise. Moreover, it is possible to maintain a sufficient air cleaning ability operated to perform a second operation within the set time T ₂ of the timer T ₂ set in step S ₆ in airflow levels. As a result, stable pollen absorption and purification and deodorization are maintained in a relatively quiet state with sufficient cleaning ability to form gentle convection throughout the room.

[0075] Then, further the second course of operating the timer T ₂ of the set time t ₂ in step S ₇ is determined, in turn proceeds to step S _8, S _9, the weak level the fan air volume set to the third operating timer T ₃ by within set operating time T _3, operating in light winds. In this state, most of the pollen smoke generated in the room when pollen is generated is smoothly suctioned and cleaned, and there is no fear that the room will be filled.

[0076] Then, when the course of the third operational timer T ₃ of the set time T ₃ is determined in step S _10, once the fan is turned OFF in step S _11, is set to the OFF state at step S ₁₂ It continues fourth operational timer T ₄ OFF within the set time T ₄ has. Then, the OF in step S ₁₃
Determines whether F set time T ₄ has elapsed, when the result is YES, further when the NO after confirming whether OFF operation of the air purifier itself by users (Power OFF) is made, again above continue to absorb cleaning and deodorizing pollen remaining running intermittent operation of a fan Kazeryoujaku level state proceeds to the step S ₈ the following operation is performed oN, the OFF operation at an extremely quiet light winds .

As a result, a stable air cleaning state can be always maintained with low power consumption.

Next, the contents of the air cleaning control pollen mode by auto system using a sensor DS ₁ output of the system with reference to the flowchart of FIG. 11 will be described in detail.

[0079] That is, first in step S _1, the same current is selected setting mode determines whether the "pollen mode".

As a result, when the result is YES, the process proceeds to step S ₂ , in which the fan 2 is driven at the maximum rotation speed such that the fan air volume is at the strong level which is the maximum capacity, and sufficient convection is formed in the air in the entire room. Then, the pollen distributed on the floor surface is sufficiently soared into the air to absorb the pollen as efficiently as possible, thereby purifying the entire indoor air. Operation with the fan air flow strong level, so inevitably noise is high, the entire room as above the convection is formed in the air, first the pollen not seen mud set in step S ₃ that can be cleaned operation timer T ₁ of the minimum required set time T within ₁ continues only until the elapsed is determined in step S _4.

When it is determined in step S ₄ that the same time T ₁ has elapsed, the process proceeds to step S ₅ , in which the fan is not high in noise and can maintain a sufficient pollen air cleaning ability. operated to perform a second operation within the set time T ₂ of the timer T ₂ set in step S ₆ in airflow levels. As a result, stable pollen cleaning and deodorizing effects are maintained in a relatively quiet state with sufficient cleaning ability to form gentle convection throughout the room.

[0082] When the further set time t ₂ has elapsed the second same operation timer T ₂ at step S ₇ is determined, then enter the detection output Vo of the sensor proceeds to step S _8, the following step determining S ₉ detection output Vo is a predetermined set reference value Vs or more corresponding to the pollen mode, that is fouling degree of pollen, whether odor level is in the set level or more.

[0083] Then, as a result, when it is determined that YES is then third operational timer T ₃ by the setting operation time T within ₃ to set the fan air volume to the weak level proceeds to step S _10, Operate in low breeze conditions. Thus, most of the pollen at the time of pollen generation is suctioned and cleaned more smoothly.

[0084] Then, the set operation time in step S ₁₂ T
If the course of ₃ is determined, once the fan OFF, continues fourth operational timer T within ₄ OFF setting time T _4, which is set to the OFF state at step S ₁₄ in step S _13. Then, it is determined whether or not the OFF setting time T ₄ has elapsed in step S _15, when the YES further step S
_After confirming whether or not the user has turned off the air purifier itself (power OFF) in step ₁₆ , if the result is NO, the operation proceeds to step S _{8 and the} following steps again to perform the intermittent operation in the state of the low fan air flow level. And continue to clean the remaining pollen, turning on and off in extremely quiet breeze
Perform FF operation.

As a result, a stable air cleaning state can be always maintained with low power consumption.

[0086] Juan other hand, when the cleaning of the pollen mode in which the detection output Vo of the sensor is determined to be lower than the set reference value Vs in step S ₉ has been completed, the process proceeds to step S ₁₇ 2 is turned off.

As a result, unlike the manual system described above, when the pollen air cleaning and deodorization are completed, the completion of the cleaning and deodorization is automatically determined based on the output of the sensor, and the air purifier is operated. Operation can be stopped automatically.
