Description

空気清浄機Air cleaner
　本発明は空気清浄機に関するもので、詳しくは回復可能な脱臭部を備えた空気清浄機に関するものである。 The present invention relates to an air purifier, and more particularly to an air purifier having a recoverable deodorizing part.
　従来、回復可能な脱臭部を備えた空気清浄機として、臭気成分を吸着するための吸着材の表面に触媒を添着してなる脱臭部と、この脱臭部の脱臭機能を回復するために加熱する加熱部を有する構成のもの（例えば、特許文献１参照）が知られている。 Conventionally, as an air cleaner equipped with a recoverable deodorizing part, a deodorizing part formed by attaching a catalyst to the surface of an adsorbent for adsorbing odorous components and heating to recover the deodorizing function of this deodorizing part The thing of the structure which has a heating part (for example, refer patent document 1) is known.
　従来の空気清浄機は、室内空気を取り込み、集塵フィルターにて塵埃を除去した後、消臭部に流下した室内空気中の臭気成分が、消臭部の吸着材に吸着することにより、室内空気の脱臭を行う。吸着剤は臭気成分を吸着するにつれて脱臭性能が落ちてしまうが、臭気を吸着した脱臭部の吸着材を加熱部により加熱することで、臭気成分が除去されて、脱臭機能を回復させることができるようになっている。 A conventional air cleaner takes in indoor air, removes dust with a dust collection filter, and then the odor components in the indoor air that have flowed down to the deodorizing part are adsorbed on the adsorbent of the deodorizing part, thereby Deodorize the air. As the adsorbent adsorbs odorous components, the deodorizing performance declines, but the odorous components are removed and the deodorizing function can be restored by heating the adsorbent of the deodorizing part that adsorbs odors with the heating part. It is like that.

　しかしながら特許文献１に記載の従来の空気清浄機においては、運転開始時からの累積運転時間をみており、累積運転時間が所定の時間に達すると脱臭機能を回復させるべくヒーター通電を行い、脱臭機能回復運転を実施する。 However, in the conventional air cleaner described in Patent Document 1, the accumulated operation time from the start of operation is observed, and when the accumulated operation time reaches a predetermined time, the heater is energized to recover the deodorization function, Perform recovery operation.
　脱臭機能回復運転中は脱臭部の吸着材を高温にさせる必要が有る為、ファンモーターを停止させヒーター通電を行う。よってこの間は脱臭運転を行うことが出来ないため、室内の臭気が高く脱臭運転を必要としている状況でも、脱臭運転を行うことが出来なくなるという大きな課題があった。 During the deodorizing function recovery operation, it is necessary to make the adsorbent in the deodorizing part high in temperature, so the fan motor is stopped and the heater is energized. Therefore, since the deodorizing operation cannot be performed during this period, there is a big problem that the deodorizing operation cannot be performed even in a situation where the indoor odor is high and the deodorizing operation is required.
　本発明は、前述のような課題を解決するためになされたものであり、室内空気の臭気を脱臭することを妨げず、効率よく臭気を吸着する脱臭部の機能を回復することが可能な空気清浄機を提供することを目的とする。 The present invention has been made in order to solve the above-described problems, and does not prevent deodorization of the odor of indoor air, and can recover the function of the deodorization unit that efficiently adsorbs the odor. The purpose is to provide a cleaner.
　課題を解決する本発明の空気清浄機は、空気吸込口と空気吹出口が設けられた本体ケースと、本体ケース内に設けられ、空気吸込口から空気を吸込み空気吹出口から空気を吹出すためのファンと、ファンを駆動するためのファンモーターと、ファンモーターの累積運転時間を計測する時間計測手段と、空気吸込口から吸込んだ空気に含まれる臭気を除去するための触媒が設けられた脱臭部と、脱臭部に近接して配置され、触媒を加熱して再生するための加熱部と、ファンモーターの駆動及び停止、加熱部の加熱開始及び加熱停止を制御する制御部と、空気の臭気を計測するニオイセンサーと、ニオイセンサーの出力により臭気レベルを測定する臭気レベル測定手段とを備え、ファンモーターの累積運転時間が所定の設定時間Ｔ１を経過したときに、ニオイセンサーが計測する臭気レベルが所定の設定臭気レベル以下であれば加熱部の加熱を開始し、所定の設定臭気レベルを超過していれば加熱部の加熱を開始しないようにしたものである。 An air cleaner of the present invention that solves the problem is provided in a main body case provided with an air suction port and an air outlet, and is provided in the main body case for sucking air from the air suction port and blowing out air from the air outlet. Deodorization provided with a fan, a fan motor for driving the fan, a time measuring means for measuring the cumulative operation time of the fan motor, and a catalyst for removing odor contained in the air sucked from the air suction port A heating unit for heating and regenerating the catalyst, a control unit for controlling the driving and stopping of the fan motor, the heating start and stop of heating of the heating unit, and the odor of air And an odor level measuring means for measuring the odor level based on the output of the odor sensor, and the cumulative operation time of the fan motor has passed a predetermined set time T1. When the odor level measured by the odor sensor is equal to or lower than the predetermined set odor level, heating of the heating unit is started, and when the predetermined odor level is exceeded, heating of the heating unit is not started. It is.
　本発明によれば、室内の臭気レベルに応じて、脱臭機能回復運転を開始せず空気清浄（脱臭）運転を優先するようにしたので使用者が使いたい時に空気清浄（脱臭）運転をすることができ、使用者の利便性が向上する。 According to the present invention, according to the odor level in the room, the deodorizing function recovery operation is not started and the air cleaning (deodorizing) operation is given priority. This improves user convenience.

　なお、それぞれの図において、同じ部分または相当する部分には同じ符号を付し、一部の説明を省略する。また、複数の部材であって、符号に「ａ、ｂ等」を付記するものについて、共通する内容を説明する際には、符号に付した「ａ、ｂ等」を削除して、その一方の部材について説明する場合がある。
　以下、図１から図３により本発明の実施の形態１に係る空気清浄機の構成について説明する。 In the respective drawings, the same or corresponding parts are denoted by the same reference numerals, and a part of the description is omitted. In addition, when explaining the common contents of a plurality of members with “a, b, etc.” added to the reference sign, “a, b, etc.” attached to the reference sign is deleted, The member may be described.
Hereinafter, the configuration of the air cleaner according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 3.
　図１（ａ）～（ｃ）に示すように１００は空気清浄機であり、略直方体の本体ケース１で構成され、その上面部に、空気清浄機１００の移動、持ち運びのためのハンドル２が設けられている。上面部のハンドル２よりも前方の操作し易い位置に、空気清浄機１００を動作させるための入力を行う複数の操作ボタン（図示せず）や表示手段（図示せず）等からなる操作部３が設けられている。 As shown in FIGS. 1 (a) to 1 (c), reference numeral 100 denotes an air purifier, which is composed of a substantially rectangular parallelepiped main body case 1, and a handle 2 for moving and carrying the air purifier 100 is provided on the upper surface thereof. Is provided. An operation unit 3 composed of a plurality of operation buttons (not shown), display means (not shown) and the like for performing input for operating the air purifier 100 at a position easier to operate than the handle 2 on the upper surface. Is provided.
　空気清浄機１００の下面側には、空気清浄機１００を持ち上げることなく移動させられるように複数のキャスター１７が設けられていて、移動させ易くなっている。 A plurality of casters 17 are provided on the lower surface side of the air purifier 100 so that the air purifier 100 can be moved without being lifted, and can be easily moved.
　空気清浄機１００の前側には、着脱自在の前側カバー７が設けられていて後述する集塵フィルター８の交換の際に取外すようになっている。前側カバー７には複数の桟のようになっている空気吸込口４が設けられている。 A detachable front cover 7 is provided on the front side of the air purifier 100 and is removed when the dust collection filter 8 described later is replaced. The front cover 7 is provided with air suction ports 4 that are like a plurality of crosspieces.
　空気清浄機１００の右側側面下方には、室内空気に含まれる臭気成分を検出するニオイセンサー６が設けられている。 An odor sensor 6 that detects odor components contained in room air is provided below the right side surface of the air cleaner 100.
　図２に示すように、本体ケース１内には、前側カバー７を取り外すと現れる集塵フィルター８が着脱自在に配設されている。集塵フィルター８は吸込んだ室内空気に含まれる塵埃等を捕集、除去するためのもので、所定の期間（例えば１０年間）使用するとフィルターの目詰り等により塵埃等の捕集、除去性能低下及び空気通過量の低下することがあるので交換されるものであり、空気吸込口４の近傍に設けられる。 As shown in FIG. 2, a dust collection filter 8 that appears when the front cover 7 is removed is detachably disposed in the main body case 1. The dust collection filter 8 is for collecting and removing dust contained in the inhaled room air. When used for a predetermined period (for example, 10 years), the dust collection and removal performance decreases due to clogging of the filter. In addition, the air passing amount may be reduced, so that the air passing amount is replaced and is provided in the vicinity of the air suction port 4.
　集塵フィルター８の奥側には脱臭部９が設けられている。脱臭部９は集塵フィルター８によって塵埃等が除去された空気に含まれる臭気成分を吸着、除去するためのもので、例えば金属等の素材にゼオライト、アルミナ、シリカ、貴金属、希土類酸化物などからなる脱臭機能を有する触媒を含浸または塗布したものである。 A deodorizing section 9 is provided on the back side of the dust collection filter 8. The deodorizing unit 9 is for adsorbing and removing odorous components contained in the air from which dust and the like have been removed by the dust collecting filter 8. For example, a material such as metal is made of zeolite, alumina, silica, noble metal, rare earth oxide, etc. A catalyst having a deodorizing function is impregnated or applied.
　触媒は、臭気成分を吸着することにより脱臭機能が低下していくが、加熱することにより触媒を再生し脱臭機能を回復させることができる。但し１００％の回復ではないので所定の期間使用すると交換が必要となる。そのため、脱臭部９は取外し自在に取り付けられている。また、脱臭部９の交換時期については、後述するファンモーター１２の累積運転時間により経年累積時間を計時し、その結果を図示しない操作部３の表示手段に表示することで交換時期を使用者に知らせることも可能である。 The catalyst has a deodorizing function that is reduced by adsorbing an odor component, but heating can regenerate the catalyst and restore the deodorizing function. However, since the recovery is not 100%, replacement is necessary after a predetermined period of use. Therefore, the deodorizing part 9 is detachably attached. As for the replacement time of the deodorizing unit 9, the elapsed time is measured by the cumulative operation time of the fan motor 12, which will be described later, and the result is displayed on the display means of the operation unit 3 (not shown) so that the user can know the replacement time. It is also possible to inform.
　加熱部１０は、脱臭部９の触媒を再生し脱臭機能を回復させるためのもので、例えばＰＴＣ（正温度係数）ヒーターのようなヒーターを有している。ここで正温度係数とはヒーター温度が上昇するにしたがい、電気抵抗値も上昇し、正の係数値が変化する特性のことである。ＰＴＣヒーターとは温度が上昇すると電気抵抗値が上昇し電流値をさげることで温度上昇を抑制することができるヒーターのことである。従って、ＰＴＣヒーターは、適温を継続するには好適である。但し、加熱部１０に使用されるヒーターはこれに限定されるものではなく、ニクロム線等による電熱ヒーター等を使用してもよい。 The heating unit 10 is for regenerating the catalyst of the deodorizing unit 9 and restoring the deodorizing function, and has a heater such as a PTC (positive temperature coefficient) heater. Here, the positive temperature coefficient is a characteristic in which the electrical resistance value increases and the positive coefficient value changes as the heater temperature increases. The PTC heater is a heater that can suppress an increase in temperature by increasing an electric resistance value and decreasing a current value when the temperature increases. Therefore, the PTC heater is suitable for maintaining an appropriate temperature. However, the heater used for the heating unit 10 is not limited to this, and an electric heater using a nichrome wire or the like may be used.
　本体ケース１内の背面側には室内空気を吸込み排出するためのファン１１と、ファン１１を駆動するためのファンモーター１２とが設けられている。 A fan 11 for sucking and discharging room air and a fan motor 12 for driving the fan 11 are provided on the back side in the main body case 1.
　さらに本体ケース１内の背面側下方には、操作部３から入力された操作内容に従い、所定のプログラムに基づいて空気清浄機１００の動作を制御するための制御手段１３が設けられている。 Further, a control means 13 for controlling the operation of the air purifier 100 based on a predetermined program according to the operation content input from the operation unit 3 is provided below the back side in the main body case 1.
　ここで図２に示す一連の空気の流れＷ（以下、空気の流れＷを通風路という）により空気清浄の工程を説明すると、操作部３から入力された操作内容に従い、所定のプログラムに基づいて空気清浄機１００の動作を制御するための制御手段１３がファンモーター１２の駆動を開始させる。 Here, the air cleaning process will be described with a series of air flows W (hereinafter referred to as air passages W) shown in FIG. 2, according to the operation contents input from the operation unit 3 and based on a predetermined program. The control means 13 for controlling the operation of the air cleaner 100 starts driving the fan motor 12.
　ファンモーター１２の駆動によりファン１１が回転し、空気吸込口４から室内空気が吸込まれ、集塵フィルター８により室内空気に含まれる塵埃等が捕集、除去される。その後、塵埃等が捕集、除去された室内空気は脱臭部９を通過し臭気成分が吸着、除去される。 When the fan motor 12 is driven, the fan 11 is rotated, the room air is sucked from the air suction port 4, and the dust or the like contained in the room air is collected and removed by the dust collection filter 8. Thereafter, the room air from which dust and the like have been collected and removed passes through the deodorizing unit 9, and odor components are adsorbed and removed.
　そして、清浄された室内空気はファン１１を経由し、本体ケース１の上面部でハンドル２よりも後方に設けられた空気吹出口５より排出されて室内に戻され、これを繰り返すことで室内空気が清浄される。 Then, the cleaned room air passes through the fan 11 and is discharged from the air outlet 5 provided behind the handle 2 on the upper surface portion of the main body case 1 and returned to the room. Is cleaned.
　脱臭部９と加熱部１０について図３により詳しく説明すると、図３に示すように脱臭部９は９ａから９ｈ（９ｈは加熱部１０に隠れているため図示せず）に八等分されている。 The deodorizing unit 9 and the heating unit 10 will be described in detail with reference to FIG. 3. As shown in FIG. 3, the deodorizing unit 9 is divided into eight equal parts from 9a to 9h (9h is not shown because it is hidden by the heating unit 10). .
　脱臭部９は吸込んだ室内空気の臭気成分を吸着、除去するため通風路全域をカバーする大きさに設定されているが、前述のように脱臭機能が低下していくため加熱することにより触媒を再生させ脱臭機能を回復しなければならない。 The deodorization unit 9 is set to a size that covers the entire ventilation path in order to adsorb and remove the odor components of the inhaled indoor air. However, as described above, since the deodorization function is lowered, the catalyst is removed by heating. It must be regenerated and deodorized.
　加熱部１０は脱臭部９と対向する位置で通風路を遮るように配置しなければならないため、大きくすると通風路を遮る面積が大きくなり空気清浄機能が低下してしまう。よって空気清浄機能が低下しない程度に通風路が確保できる大きさにする必要がある。 Since the heating unit 10 must be disposed so as to block the ventilation path at a position facing the deodorizing unit 9, if the heating unit 10 is increased, the area blocking the ventilation path is increased, and the air cleaning function is deteriorated. Therefore, it is necessary to make it a size that can secure the ventilation path to such an extent that the air cleaning function does not deteriorate.
　本実施の形態では加熱部１０を、脱臭部９の八分の一をカバーする大きさに設定したものを、一例とする。加熱部１０は、脱臭部９の各箇所（９ａ～９ｈ）のうち一箇所を所定の時間加熱することにより、その箇所の触媒を再生し脱臭機能を回復させる。その後、脱臭部９の外周に設けられた歯車１８と脱臭部回転用モーター１４とにより、脱臭部９が略４５度回転し、同様に、加熱部１０により、所定の時間、脱臭部９の次の箇所を加熱することにより触媒を再生し脱臭機能を回復させる。この動作を繰り返し、脱臭部９全体の脱臭機能回復をするようになっている。 In the present embodiment, the heating unit 10 is set to a size that covers an eighth of the deodorizing unit 9 as an example. The heating unit 10 regenerates the catalyst at that portion and restores the deodorizing function by heating one portion of the portions (9a to 9h) of the deodorizing unit 9 for a predetermined time. Thereafter, the deodorizing unit 9 is rotated approximately 45 degrees by the gear 18 provided on the outer periphery of the deodorizing unit 9 and the motor 14 for rotating the deodorizing unit. Similarly, the heating unit 10 continues the deodorizing unit 9 for a predetermined time. The catalyst is regenerated and the deodorizing function is restored by heating the part. This operation is repeated to recover the deodorizing function of the entire deodorizing unit 9.
　本実施の形態では後述する動作のところで一例を説明するが、脱臭運転を２３時間１０分実施した後、脱臭部９を加熱して触媒を再生させ脱臭機能を回復する運転を５０分実施する。その後、脱臭部９を回転させる。つまり２４時間周期で一箇所が回転するようになっている。但し、八分の一ずつ機能回復させるように設定することに限定されるものではなく、九分の一や十分の一ずつ機能回復させるように設定してもよい。 In this embodiment, an example will be described in the operation described later, but after performing the deodorizing operation for 23 hours and 10 minutes, the operation for regenerating the deodorizing function by heating the deodorizing unit 9 and recovering the deodorizing function is performed for 50 minutes. Then, the deodorizing part 9 is rotated. That is, one place rotates in a 24-hour cycle. However, it is not limited to setting the function to be restored by one-eighth, but may be set to restore the function by one-tenth or one-tenth.

　以下、図４から図６により本発明の実施の形態１に係る空気清浄機の動作について説明する。 (Operation)
4 is a block diagram of the control system of the air cleaner according to Embodiment 1 of the present invention, FIG. 5 is a flowchart showing the operation of the air cleaner according to Embodiment 1 of the present invention, and FIG. 6 is a six-stage odor. It is the odor table which made the odor density | concentration of ammonia correspond to the level.
Hereinafter, operation | movement of the air cleaner which concerns on Embodiment 1 of this invention with reference to FIGS. 4-6 is demonstrated.
　図４に示すように、操作部３からの入力は制御手段１３に内包された制御部１９により制御され、ファンモーター１２の駆動指示及び加熱部１０の加熱指示がなされるようになっている。ファンモーター１２が駆動を開始すると、制御手段１３に内包された累積運転時間計時手段１５によりファンモーター１２の累積運転時間がカウントされ、制御部１９に累積運転時間の情報が送られる。 As shown in FIG. 4, the input from the operation unit 3 is controlled by a control unit 19 included in the control unit 13, and a drive instruction for the fan motor 12 and a heating instruction for the heating unit 10 are made. When the fan motor 12 starts driving, the cumulative operation time counting means 15 included in the control means 13 counts the cumulative operation time of the fan motor 12 and sends information on the cumulative operation time to the control unit 19.
　同様に加熱部１０の加熱が開始すると、制御手段１３に内包された動作時間計時手段２０により加熱部１０の動作時間がカウントされ、制御部１９に動作時間の情報が送られる。なお、後述するフローで説明するように、ファンモーター１２の駆動と加熱部１０の加熱は同時に行われることはない。 Similarly, when heating of the heating unit 10 is started, the operation time of the heating unit 10 is counted by the operation time counting unit 20 included in the control unit 13, and information on the operation time is sent to the control unit 19. In addition, as will be described in a flow described later, the driving of the fan motor 12 and the heating of the heating unit 10 are not performed simultaneously.
　室内空気の臭気成分を検知するニオイセンサー６の検知データの出力は、制御手段１３に内包された臭気レベル測定手段１６に送られ、臭気レベル測定手段１６が図６に示す臭気濃度のテーブルと比較し、臭気レベルの情報が制御部１９へ送られる。臭気濃度のテーブルは予め制御手段１３に内包された記憶手段（図示せず）に記憶されており、ニオイセンサー６の検知データと比較されるようになっている。 The output of the detection data of the odor sensor 6 for detecting the odor component of the indoor air is sent to the odor level measuring means 16 included in the control means 13, and the odor level measuring means 16 compares it with the odor concentration table shown in FIG. Then, the odor level information is sent to the control unit 19. The odor concentration table is stored in advance in storage means (not shown) included in the control means 13 and is compared with the detection data of the odor sensor 6.
（フロー）
　次に図５により動作の流れを説明する。操作部３の入力により運転が開始され、ファンモーター１２がＯＮとなり空気清浄動作が開始される（ステップ１、以下ステップはＳと表しこの場合Ｓ１となる）。 (flow)
Next, the operation flow will be described with reference to FIG. The operation is started by the input of the operation unit 3, the fan motor 12 is turned on, and the air cleaning operation is started (step 1, hereinafter, step is denoted as S and in this case, it is S 1).
　ファンモーター１２の駆動と同時に累積運転時間ＴＸの計時が開始され（Ｓ２）、ニオイセンサーの検知データと臭気濃度テーブルとの比較により臭気レベルの測定が行われる（Ｓ３）。 Simultaneously with the driving of the fan motor 12, counting of the cumulative operation time TX is started (S2), and the odor level is measured by comparing the detection data of the odor sensor with the odor concentration table (S3).
　空気清浄動作を開始してからファンモーター１２の累積運転時間ＴＸが、予め設定された設定時間Ｔ１未満の場合は空気清浄動作が継続され、ファンモーター１２が駆動を続ける（Ｓ４）。本実施の形態１ではＴ１を２３時間１０分で設定している。 When the cumulative operation time TX of the fan motor 12 after the start of the air cleaning operation is less than the preset time T1, the air cleaning operation is continued and the fan motor 12 continues to drive (S4). In the first embodiment, T1 is set to 23 hours and 10 minutes.
　Ｓ４において、ファンモーター１２の累積運転時間ＴＸが、予め設定された設定時間Ｔ１以上となった場合にはＳ５に進み、臭気レベルが予め設定された設定臭気レベルと比較される。本実施の形態１では図６の臭気濃度テーブルにおける臭気レベル３を設定臭気レベルとしている。 In S4, when the cumulative operation time TX of the fan motor 12 becomes equal to or longer than the preset set time T1, the process proceeds to S5, and the odor level is compared with the preset odor level. In the first embodiment, the odor level 3 in the odor concentration table of FIG. 6 is set as the set odor level.
　Ｓ５において、臭気レベルが設定臭気レベル（臭気レベル３）未満の場合は空気清浄動作を停止してもよいと判断し、ファンモーター１２をＯＦＦし空気清浄動作を停止させる（Ｓ６）。同時に累積運転時間ＴＸの計時も停止する。 In S5, if the odor level is less than the set odor level (odor level 3), it is determined that the air cleaning operation may be stopped, and the fan motor 12 is turned off to stop the air cleaning operation (S6). At the same time, the counting of the cumulative operation time TX is also stopped.
次に加熱部１０をＯＮして触媒の加熱を開始し加熱（触媒を再生し脱臭機能の回復）動作に入る（Ｓ７）。ここで、加熱部１０の加熱と同時に加熱動作時間ＴＺの計時が開始される（Ｓ８）。 Next, the heating unit 10 is turned on to start heating the catalyst, and the heating (regeneration of the catalyst and recovery of the deodorizing function) starts (S7). Here, the heating operation time TZ is started simultaneously with the heating of the heating unit 10 (S8).
　加熱動作を開始してから加熱部１０の動作時間ＴＺが、予め設定された設定時間Ｔ２未満の場合は加熱動作が継続され、加熱部１０が加熱を続ける（Ｓ９）。本実施の形態１ではＴ２を５０分で設定している。 When the operation time TZ of the heating unit 10 is less than the preset set time T2 after starting the heating operation, the heating operation is continued, and the heating unit 10 continues heating (S9). In the first embodiment, T2 is set to 50 minutes.
Ｓ９において、加熱部１０の動作時間ＴＺが、予め設定された設定時間Ｔ２以上となった場合にはＳ１０に進み、加熱部１０をＯＦＦし再びＳ１へ進みファンモーター１２がＯＮされ空気清浄動作が再開される。 In S9, when the operation time TZ of the heating unit 10 is equal to or longer than the preset set time T2, the process proceeds to S10, the heating unit 10 is turned off, the process proceeds to S1 again, the fan motor 12 is turned on, and the air cleaning operation is performed. Resumed.
　Ｓ５において、設定臭気レベル（臭気レベル３）以上の場合は空気清浄動作を継続する必要があると判断し、Ｓ１へ進みファンモーター１２の駆動を続け空気清浄動作を継続させる。このフローはＳ５で臭気レベルが予め設定された設定臭気レベルと比較されて、臭気レベルが設定臭気レベル（臭気レベル３）未満となるまで継続される。 In S5, if it is equal to or higher than the set odor level (odor level 3), it is determined that it is necessary to continue the air cleaning operation, and the process proceeds to S1 to continue driving the fan motor 12 and continue the air cleaning operation. This flow is continued until the odor level becomes lower than the set odor level (odor level 3) as compared with the set odor level set in advance in S5.
　以上のように本発明の実施の形態１においては、測定した室内の臭気レベルが設定臭気レベル以上の場合、ファンモーター１２の累積運転時間ＴＸが、予め設定された設定時間Ｔ１以上となった場合でも空気清浄動作を継続するようにしたので、使用者が空気清浄させたい臭気レベルのときに脱臭機能の回復が優先されることがなく、使用者にストレスを感じさない空気清浄機の利便性を向上させることができる。 As described above, in Embodiment 1 of the present invention, when the measured indoor odor level is greater than or equal to the set odor level, the cumulative operation time TX of the fan motor 12 is greater than or equal to the preset set time T1. However, since the air purifying operation is continued, the recovery of the deodorizing function is not given priority when the odor level that the user wants to clean the air, and the convenience of the air purifier that does not feel stress to the user. Can be improved.
