Abstract

Air conditioner in which the amount of dust collected in a dust box is more accurately determined in a practical manner and the arrival of the time for dust box maintenance is notified at an appropriate timing. The air conditioner has determination means for determining the amount of dust collected in the dust box (20) and outputting a maintenance signal when the amount of dust reaches a preset standard amount for maintenance, and also has notifying means for notifying the necessity of maintenance of the dust box (20) upon receiving a maintenance signal from the determination means. Because the above construction determines the amount collected in the dust box (20) and performs notification for maintenance based on the determination, inappropriate determination such as that seen in a case in which the determination is based on the frequency of cleaning of a filter (13) and in which the amount of dust collected in the filter (13) is estimated based on accumulated time of air conditioning operation does not occur. In the air conditioner of the invention, notification for maintenance of the dust box (20) and maintenance based on the notification can be performed at a more appropriate timing.

[0001] 本願発明は、空調機構に、フィルタの掃除機構を付加してなる空気調和機に関す るものである。  [0001] The present invention relates to an air conditioner in which a filter cleaning mechanism is added to an air conditioning mechanism.
背景技術  Background art
[0002] 従来から、フィルタを自動的に掃除する掃除機構を備えた空気調和機が知られて いる（特許文献 1参照）。この空気調和機におけるフィルタの掃除機構は、空気吸入 口の内面に沿って往復動自在に配置された板状のフィルタを、該フィルタの移動経 路中に配置したダストボックス内を通過させるとともに、該ダストボックス内において該 フィルタの表裏両面に配置したブラシによって、該フィルタの表面に付着したゴミを除 去することで該フィルタの機能再生を図るようにしたものである。そして、ダストボックス 内に溜まったゴミの量が多くなると、該ダストボックスを取外してゴミを捨てた後、再度 これを装着するメンテナンス作業が必要となる。  Conventionally, an air conditioner equipped with a cleaning mechanism that automatically cleans a filter is known (see Patent Document 1). The filter cleaning mechanism in this air conditioner passes a plate-like filter arranged reciprocally along the inner surface of the air suction port through a dust box arranged in the movement path of the filter, and The function of the filter is regenerated by removing dust adhering to the surface of the filter with brushes arranged on both sides of the filter in the dust box. When the amount of dust accumulated in the dust box increases, it is necessary to remove the dust box, throw away the dust, and then perform maintenance work to attach the dust box again.
この場合、メンテナンス作業の必要性を判断するには、ダストボックスに溜まるゴミの 量を直接検知するのが最善な手法であるが、係る手法では、ゴミの特性等から、特殊 なセンサを必要とするなど、コスト面等からして実現は困難である。  In this case, the best way to determine the necessity of maintenance work is to directly detect the amount of dust collected in the dust box. However, this method requires a special sensor due to the characteristics of the dust. It is difficult to realize from the viewpoint of cost.
[0003] このため、特許文献 1に示された空気調和機では、空調運転の運転積算時間（即 ち、フィルタにおける積算通風時間）に基づいてフィルタに溜まるゴミの量を推測する ことを基本思想とし、その上で、運転積算時間が所定値以上となったときには、ダスト ボックスにも所定量以上のゴミが溜まっておりメンテナンスが必要であると判断する手 法が提案されている。  [0003] For this reason, the basic concept of the air conditioner disclosed in Patent Document 1 is to estimate the amount of dust accumulated in the filter based on the accumulated operation time of the air conditioning operation (that is, the accumulated ventilation time in the filter). In addition, a method has been proposed in which when the accumulated operating time exceeds a predetermined value, a predetermined amount or more of dust has accumulated in the dust box and maintenance is required.

発明が解決しょうとする課題  Problems to be solved by the invention
[0004] しかし、フィルタに溜まるゴミの量は空調運転の運転積算時間と必ずしも相関するも のではなぐ例えば、フィルタを掃除する頻度によって大きく変化するものである。 即ち、フィルタの掃除頻度が高ければ、ゴミによるフィルタの目詰まりが少なぐフィ ルタは常に設計性能に近いフィルタ機能を発揮し、予定された以上に細力、いゴミは 捕集されない。これに対して、フィルタの掃除頻度が低ければ、ゴミによるフィルタの 目詰まりが多くなり、その結果、フィルタは本来予定された以上に細力、ぃゴミまで捕集 することとなり、その分だけフィルタに溜まるゴミの量が多くなるものである。 [0004] However, the amount of dust accumulated in the filter does not necessarily correlate with the integrated operation time of the air conditioning operation. For example, it greatly varies depending on the frequency of cleaning the filter. In other words, if the frequency of cleaning the filter is high, the filter with less filter clogging with dust will always exhibit a filter function close to the design performance, and will not collect finer and more dust than planned. On the other hand, if the frequency of cleaning the filter is low, the filter will be clogged with dust, and as a result, the filter will collect more dust and dust than originally planned, and the filter will be correspondingly removed. The amount of trash that accumulates in is increased.
従って、単に、空調運転の運転積算時間に基づいてダストボックスのメンテナンス 時期を判断したのでは、現実に即した適切は判断ができず、例えば、ダストボックス に溜まったゴミの量が少ないにも拘らずメンテナンス時期の到来を告知したり、逆に ダストボックスに多量のゴミが溜まっているにも拘らずメンテナンス時期の到来を告知 せず、場合によってはダストボックスから室内にゴミが飛散して室内環境の悪化を招 来するということも考えられる。  Therefore, simply judging the maintenance time of the dust box based on the accumulated operation time of the air conditioning operation cannot make an appropriate judgment in accordance with the actual situation.For example, although the amount of dust collected in the dust box is small, maintenance is not possible. Notifying the arrival of the time, or conversely, notifying the arrival of the maintenance time even though a large amount of dust is accumulating in the dust box. It is possible to come.
[0005] そこで本願発明は、ダストボックスに溜まったゴミの量を現実に即してより的確に判 断してダストボックスのメンテナンス時期の到来を適切なタイミングで告知し、もってフ ィルタ掃除機能を備えた空気調和機の機能維持を図ることを目的としてなされたもの である。 [0005] Therefore, the present invention has a filter cleaning function by determining the amount of dust accumulated in the dust box more accurately in accordance with the actual situation, and notifying the arrival of the maintenance time of the dust box at an appropriate timing. The purpose is to maintain the function of the air conditioner.

発明の効果  The invention's effect
[0013] 本願発明では次のような効果が得られる。 In the present invention, the following effects can be obtained.
第 1発明に係る空気調和機では、上記ダストボックス 20に溜まるゴミの量を判断しそ の量が予め設定されたメンテナンス基準量に達したときメンテナンス信号を出力する 判断手段と、上記判断手段からのメンテナンス信号を受けて上記ダストボックス 20の メンテナンスを告知する告知手段を備えて!/、る。  In the air conditioner according to the first aspect of the present invention, a judgment means for judging the amount of dust accumulated in the dust box 20 and outputting a maintenance signal when the quantity reaches a preset maintenance reference quantity, and maintenance from the judgment means Provide a notification means to notify the maintenance of the dust box 20 in response to the signal!
従って、この発明の空気調和機によれば、上記判断手段により上記ダストボックス 2 0に溜まるゴミの量を判断し、この判断に基づいて上記告知手段力 Sメンテナンスを告 知することから、例えば、従来のように、空調運転の運転積算時間からフィルタに溜ま つたゴミの量を推測し、これに基づ!/、てダストボックスのメンテナンスを告知する構成 のように、フィルタの掃除頻度の高低による不適切な判断が生じないことから、ダスト ボックス 20のメンテナンスの告知をより適切なタイミングで行なうことができ、その結果 、不必要なメンテナンスの実行に伴い空調運転が停止されることによる室内空調の快 適性の低下とか、ダストボックス 20にゴミが過度に溜まってゴミが室内へ飛散すること による室内環境の悪化等が防止され、それだけ空気調和機の性能特性の向上が期 待できる。 [0014] 第 2発明に係る空気調和機では、上記判断手段が、上記掃除機構 Yの動作回数に 基づいて上記ダストボックス 20内のゴミの量を判断するように構成しているので、上 記掃除機構 Yの 1回の動作によって上記ダストボックス 20側に捕集されるゴミの量と、 該掃除機構 Yの動作回数との相関から、上記ダストボックス 20内のゴミの量を判断し てメンテナンスの告知を行なうことができ、例えば、従来のように、空調運転の運転積 算時間からフィルタに溜まったゴミの量を推測し、これに基づいてダストボックスのメン テナンスの告知を行なう構成の場合に比して、上記ダストボックス 20内のゴミの量の 判断ロジックがより簡略化され、延いては、掃除機構 Yの低コスト化が促進される。 第 3発明に係る空気調和機では、上記メンテナンス基準量を上記掃除機構 Yの動 作回数で規定しているので、上記ダストボックス 20内のゴミの量の判断と、メンテナン ス基準量に基づくメンテナンス告知の判断との対応が明確であり、その結果、より簡 略化された判断ロジックで正確にメンテナンスを告知することができる。 Therefore, according to the air conditioner of the present invention, the amount of dust accumulated in the dust box 20 is determined by the determination means, and the notification means force S maintenance is notified based on this determination. As shown in this example, the amount of dust accumulated in the filter is estimated from the accumulated operation time of the air conditioning operation, and based on this, the dust box maintenance is notified. As a result, it is possible to notify the maintenance of the dust box 20 at a more appropriate timing.As a result, the air conditioning operation is stopped due to the execution of unnecessary maintenance. And the deterioration of the indoor environment due to excessive accumulation of dust in the dust box 20 and scattering of dust into the room is prevented. Improve performance characteristics of the air conditioner can be expected. [0014] In the air conditioner according to the second aspect of the invention, the determination means is configured to determine the amount of dust in the dust box 20 based on the number of operations of the cleaning mechanism Y. Notification of maintenance by judging the amount of dust in the dust box 20 from the correlation between the amount of dust collected on the dust box 20 side by one operation of mechanism Y and the number of operations of the cleaning mechanism Y For example, as compared with the conventional configuration in which the amount of dust accumulated in the filter is estimated from the accumulated operating time of the air conditioning operation, and the maintenance of the dust box is notified based on this. Therefore, the determination logic of the amount of dust in the dust box 20 is further simplified, and further, the cost reduction of the cleaning mechanism Y is promoted. In the air conditioner according to the third aspect of the invention, the maintenance reference amount is defined by the number of operations of the cleaning mechanism Y. Therefore, the determination of the amount of dust in the dust box 20 and the maintenance notification based on the maintenance reference amount are performed. As a result, the maintenance can be accurately announced with a simplified decision logic.
[0015] 第 4発明に係る空気調和機では、上記判断手段が、上記掃除機構 Yの動作間隔を 考慮して上記ダストボックス 20内のゴミの量を判断する構成であるため、上記掃除機 構 Yの動作間隔と該掃除機構 Yの 1回の動作で上記フィルタ 13側から上記ダストボッ タス 20側に捕集されるゴミの量との間には、上記掃除機構 Yの動作間隔が短い場合 は上記ダストボックス 20側に捕集されるゴミの量が少なぐ動作間隔が長い場合はゴ ミの量が多くなるという関係があることからして、上記掃除機構 Yの動作間隔の長短に よる影響を可及的に排除して、上記ダストボックス 20に実際に溜まっているゴミの量 をより精度良く検知することができる。  [0015] In the air conditioner according to the fourth aspect of the invention, the determination means is configured to determine the amount of dust in the dust box 20 in consideration of the operation interval of the cleaning mechanism Y. Between the operation interval of the cleaning mechanism Y and the amount of dust collected from the filter 13 side to the dust bot- tom 20 side in one operation of the cleaning mechanism Y, when the operation interval of the cleaning mechanism Y is short Since there is a relationship that the amount of dust increases when the amount of dust collected on the dust box 20 side is small and the operation interval is long, the effect of the length of the operation interval of the cleaning mechanism Y can be affected. The amount of dust actually accumulated in the dust box 20 can be detected with higher accuracy.
第 5発明に係る空気調和機では、上記掃除機構 Yの動作間隔が複数設定される場 合、該複数の動作間隔のそれぞれに対応して上記メンテナンス基準量も複数設定さ れるように構成しているので、例えば、空気調和機の使用者が上記掃除機構 Yの動 作間隔として、 1日に 1回の掃除運転と、 1週に 1回の掃除運転とをそれぞれ設定して いる場合に、上記メンテナンス基準量として、前者に対応する上記掃除機構 Yの動 作回数を、後者に対応する動作回数より多い回数に設定することで、使用者の要求 に対応した精度の良いメンテナンスの告知が実現される。  In the air conditioner according to the fifth aspect of the present invention, when a plurality of operation intervals of the cleaning mechanism Y are set, a plurality of the maintenance reference amounts are set corresponding to each of the plurality of operation intervals. Therefore, for example, when the user of the air conditioner sets the cleaning operation Y as the operation interval of the cleaning mechanism Y once a day and once a week, respectively. By setting the number of operations of the cleaning mechanism Y corresponding to the former as the maintenance reference amount to a number greater than the number of operations corresponding to the latter, accurate maintenance notification corresponding to the user's request is realized. Is done.
[0016] 第 6発明に係る空気調和機では、上記メンテナンス基準量を、上記告知を受けて自 動で行なう自動動作時 (即ち、上記掃除機構 Yの 1回の動作で上記ダストボックス 20 側に捕集されるゴミの量が安定しているとき）と、上記告知を受けて手動で行なう手動 動作時 (即ち、上記掃除機構 Yの 1回の動作で上記ダストボックス 20側に捕集される ゴミの量が上記告知に基づく手動での掃除の実行頻度等によって変化し易いとき）で 、異なる量に設定するようにしているので、上記掃除機構 Yの操作形態に適応したメ ンテナンスの告知が実現される。 [0016] In the air conditioner pertaining to the sixth aspect of the invention, the maintenance reference amount is determined by receiving the notification. During automatic operation (ie, when the amount of dust collected on the dust box 20 side is stabilized by one operation of the cleaning mechanism Y), and manual operation performed manually upon receiving the above notification (That is, when the amount of dust collected on the dust box 20 side by one operation of the cleaning mechanism Y is likely to change depending on the frequency of manual cleaning based on the above notification, etc.) Because it is set, maintenance notification adapted to the operation mode of the cleaning mechanism Y is realized.

そして、上記掃除ユニットケーシング 14の上記各ケーシング体 14A, 14Bの前面 側には、それぞれこれを覆うようにして、格子状の枠体 13aの内側にフィルタ 1材 13b を張設してなる板状のフィルタ 13 (図 6参照）が配置される。この場合、上記フィルタ 1 3は、上記各ケーシング体 14A, 14Bの上面側においては、その左右両縁部を上記 一方の側壁部 15のガイド溝 15aと他方の側壁部 16のガイド溝 16aに嵌入させており 、該各ガイド溝 15a, 16aにガイドされて上記各ケーシング体 14A, 14Bの湾曲方向 に沿って移動可能とされている。また、上記フィルタ 13は、上記各ケーシング体 14A , 14Bの前面部分においては、上記フィルタ押さえ 43によって浮き上がりが防止され るようになっている。  Then, on the front side of each of the casing bodies 14A and 14B of the cleaning unit casing 14, a plate-like shape in which a filter 1 material 13b is stretched inside the lattice-like frame body 13a so as to cover them. The filter 13 (see FIG. 6) is arranged. In this case, on the upper surface side of each casing body 14A, 14B, the left and right edges of the filter 13 are fitted into the guide groove 15a of the one side wall part 15 and the guide groove 16a of the other side wall part 16. The guide grooves 15a and 16a are guided by the guide grooves 15a and 16a so as to be movable along the bending directions of the casing bodies 14A and 14B. Further, the filter 13 is prevented from being lifted by the filter retainer 43 at the front portion of each casing body 14A, 14B.
[0023] 上記フィルタ 13は、図 2、図 4及び図 5に示すように、その前端 13cが、上記各ケー シング体 14A, 14Bの前面部分において、上下方向に離間して平行配置された第 1 プーリ 11と第 2プーリ 12の間に掛け回されたベルト 10に係止され、該ベルト 10の走 行に伴ってこれと一体的に移動される。  [0023] As shown in Figs. 2, 4, and 5, the filter 13 has a front end 13c disposed in parallel in the front portion of each of the casings 14A, 14B so as to be spaced apart in the vertical direction. 1 It is locked by the belt 10 wound between the pulley 11 and the second pulley 12, and is moved integrally with the belt 10 as it runs.
即ち、上記フィルタ 13は、図 2及び図 3に示すように、その後端が上記掃除ユニット ケーシング 14の後端部に位置し、その前端が上記第 1プーリ 11の近傍に位置するよ うな配置状態を基本とする。この配置状態は、通常の空調運転時における位置であり 、以下、「第 1フィルタ位置」という。 That is, as shown in FIGS. 2 and 3, the filter 13 is disposed such that its rear end is located at the rear end of the cleaning unit casing 14 and its front end is located in the vicinity of the first pulley 11. Based on. This arrangement state is the position during normal air conditioning operation. Hereinafter, it is referred to as “first filter position”.
これに対して、上記フィルタ 13の掃除を行なう掃除運転時には、上記第 1プーリ 11 が正転し、上記ベルト 10が矢印 a方向へ走行し、上記フィルタ 13は図 4に鎖線図示 するように、該ベルト 10とともに上記「第 1フィルタ位置」から上記第 1プーリ 11の外側 を迂回して上記第 2プーリ 12側まで引き出される。この時のフィルタ 13の位置を「第 2 フィルタ位置」という。また、上記第 1プーリ 11が逆転し上記ベルト 10が矢印 b方向へ 走行することで、上記フィルタ 13は該ベルト 10とともに上記「第 2フィルタ位置」から「 第 1フィルタ位置」まで戻される。  On the other hand, during the cleaning operation for cleaning the filter 13, the first pulley 11 rotates forward, the belt 10 travels in the direction of arrow a, and the filter 13 is shown by a chain line in FIG. The belt 10 is pulled out from the “first filter position” to the second pulley 12 side, bypassing the outside of the first pulley 11. The position of the filter 13 at this time is referred to as a “second filter position”. Further, when the first pulley 11 rotates in the reverse direction and the belt 10 travels in the direction of arrow b, the filter 13 is returned from the “second filter position” to the “first filter position” together with the belt 10.
[0024] このように、上記フィルタ 13が上記「第 1フィルタ位置」と「第 2フィルタ位置」の間で 往復動する際に、次述のブラシ機構 Qによって上記フィルタ 13の表面に捕集された ゴミが搔き落とされ、該フィルタ 13のゴミ捕集機能が再生されるものである。  Thus, when the filter 13 reciprocates between the “first filter position” and the “second filter position”, it is collected on the surface of the filter 13 by the brush mechanism Q described below. The dust is scraped off, and the dust collecting function of the filter 13 is regenerated.
ここで、上記フィルタ 13の駆動機構を更に詳しく説明する。この駆動機構は、図 5に 示すように、上下方向に離間配置された歯付きの第 1プーリ 11と第 2プーリ 12間に歯 付きのベルト 10を掛け回したベルトユニット Uを、上記各プーリ 11 , 12の軸方向に所 定間隔（具体的には、上記ケーシング体 14A, 14Bの略幅寸法）をもって対向配置 するとともに、一方のベルトユニット Uの第 1プーリ 11と他方のベルトユニット Uの第 1 プーリ 11の間をローラ 33によって連結しこれを一体化するとともに、一方のベルトュ ニット Uの第 2プーリ 12と他方のベルトユニット Uの第 2プーリ 12の間を連結軸 38に よって連結しこれを一体化して構成せれる。そして、一方のベルトユニット Uの第 1プ ーリ 11をフィルタ駆動モータ 31によって正転方法及び逆転方向へ選択的に回転駆 動することで、上記各ベルトユニット Uにそれぞれ設けられた上記各ベルト 10が同期 して走 fiするようになってレ、る。  Here, the drive mechanism of the filter 13 will be described in more detail. As shown in FIG. 5, this drive mechanism includes a belt unit U in which a toothed belt 10 is wound between a first pulley 11 with teeth and a second pulley 12 spaced apart in the vertical direction. 11 and 12 are arranged to face each other with a predetermined interval (specifically, approximately the width dimension of the casing bodies 14A and 14B), and the first pulley 11 of one belt unit U and the belt unit U of the other belt unit U The first pulley 11 is connected by a roller 33 to be integrated, and the second pulley 12 of one belt unit U and the second pulley 12 of the other belt unit U are connected by a connecting shaft 38. This can be integrated. Then, each belt unit U provided in each belt unit U by selectively rotating the first pulley 11 of one belt unit U in the forward rotation method and the reverse rotation direction by the filter drive motor 31. 10 will run in sync and start running.
[0025] この場合、上記ベルト 10には、所定ピッチで、ベルト長さ方向に長軸をもつ係止穴 47が形成されている。また、上記フィルタ 13の枠体 13aの左右両側部の下面には、 上記ベルト 10側の上記係止穴 47と同ピッチで係止突起 48が設けられており、該フィ ルタ 13側の上記係止突起 48を上記ベルト 10側の上記係止穴 47に係入させることで 、該フィルタ 13は上記ベルト 10と一体化され、該ベルト 10の往復走行に伴って上記 「第 1フィルタ位置」と上記「第 2フィルタ位置」の間で往復動される。 上記ブラシ機構 Qは、図 1〜図 4に示すように、上記ケーシング 1の底面壁 1Cの前 端部分に設けた収納部 30に対して着脱自在に取付けられる。このブラシ機構 Qは、 図 4及び図 7に示すように、第 1ボックス体 21と第 2ボックス体 22からなり、上記第 1プ ーリ 11の外周面に対向する上面部分が開口 20aとされた横長箱状形体のダストボッ タス 20内に、掃除ブラシ 17を上記開口 20aに沿って配置して構成される。 [0025] In this case, the belt 10 is formed with a locking hole 47 having a long axis in the belt length direction at a predetermined pitch. Further, locking projections 48 are provided on the lower surfaces of the left and right sides of the frame 13a of the filter 13 at the same pitch as the locking holes 47 on the belt 10 side, and the engagement on the filter 13 side. By engaging the stop protrusion 48 in the locking hole 47 on the belt 10 side, the filter 13 is integrated with the belt 10, and the “first filter position” as the belt 10 reciprocates. It is reciprocated between the “second filter positions”. As shown in FIGS. 1 to 4, the brush mechanism Q is detachably attached to a storage portion 30 provided at the front end portion of the bottom wall 1C of the casing 1. As shown in FIGS. 4 and 7, the brush mechanism Q includes a first box body 21 and a second box body 22, and an upper surface portion facing the outer peripheral surface of the first pulley 11 is an opening 20a. A cleaning brush 17 is arranged along the opening 20a in a dust box 20 having a horizontally long box shape.
[0026] 上記掃除ブラシ 17は、ブラシ軸 18の外周面の周方向の 4位置に、該ブラシ軸 18の 軸方向へ延出するようにしてそれぞれブラシ 19を取付けて構成される。この場合、こ の実施形態では、上記掃除ブラシ 17の軸長を、上記ダストボックス 20の長手寸法の 略半分の寸法に設定し、二本の掃除ブラシ 17を同軸上に連結して使用するようにし ている。 The cleaning brush 17 is configured by attaching brushes 19 at four positions in the circumferential direction of the outer peripheral surface of the brush shaft 18 so as to extend in the axial direction of the brush shaft 18. In this case, in this embodiment, the axial length of the cleaning brush 17 is set to approximately half the longitudinal dimension of the dust box 20, and the two cleaning brushes 17 are coaxially connected for use. ing.
このように構成された一対の掃除ブラシ 17を、図 7に示すように、上記ダストボックス 20に配置し、その一方の軸端に設けたブラシ駆動ギヤ 24をブラシ駆動モータ（図示 省略）によって回転駆動するようになっている。尚、図 7では、上記ダストボックス 20の 一端側に押釦 23を図示している力 この押釦 23は上記収納部 30側に取付けられる ものであり、ここでは上記ブラシ機構 Qとの位置関係を明確にするために便宜的に図 示したものである。  As shown in FIG. 7, the pair of cleaning brushes 17 configured in this manner is disposed in the dust box 20, and the brush drive gear 24 provided at one end of the shaft is rotationally driven by a brush drive motor (not shown). It is supposed to be. In FIG. 7, the force showing the push button 23 on one end side of the dust box 20 is shown. This push button 23 is attached to the storage portion 30 side, and here, the positional relationship with the brush mechanism Q is clearly shown. This is shown for convenience.
[0027] 図 4には、上記ブラシ機構 Qを上記ケーシング 1側の収納部 30に装着した状態を 示している。この状態では、上記ダストボックス 20の上記開口 20aが、上記第 1プーリ 11に巻き掛けられた上記ベルト 10に臨むとともに、該開口 20aを通して上記掃除ブ ラシ 17の回転軌跡が上方へ延出し、該回転軌跡の最高位部位と上記ベルト 10の外 面の最低位部位とが略合致するように、これらの相対位置が設定されている。  FIG. 4 shows a state in which the brush mechanism Q is attached to the storage unit 30 on the casing 1 side. In this state, the opening 20a of the dust box 20 faces the belt 10 wound around the first pulley 11, and the rotation locus of the cleaning brush 17 extends upward through the opening 20a. These relative positions are set so that the highest part of the locus and the lowest part of the outer surface of the belt 10 substantially coincide.
従って、掃除運転において、上記フィルタ 13が上記第 1プーリ 11に巻き掛けられた 上記ベルト 10とともに該第 1プーリ 11の外周側を迂回して「第 1フィルタ位置」と「第 2 フィルタ位置」の間で往復動される際、上記掃除ブラシ 17を回転させることで、該掃 除ブラシ 17のブラシ 19によって上記フィルタ 13の表面が撫搔され、該フィルタ 13の 表面に付着しているゴミが該表面から搔き取られ、上記ダストボックス 20内に捕集さ れる。この結果、上記フィルタ 13は、その表面が清浄化され、そのゴミ捕集機能が再 生されるものである。 [0028] また、この場合、図 4に示すように、上記掃除ブラシ 17の回転軌跡が上記ダストボッ タス 20内に設けた延出リブ 20bの先端部分と重合していることから、上記掃除ブラシ 17の回転時には上記ブラシ 19の先端部分が上記延出リブ 20bに接触し、該ブラシ 1 9側に付着しているゴミが搔き落とされる。この結果、上記ブラシ 19の搔き取り機能が 再生され、例えば、フィルタ 13側からブラシ 19によって搔き取られたゴミがそのまま該 ブラシ 19側に残留して上記フィルタ 13の既に掃除された部分に再付着するというよう な不都合が回避される。 Therefore, in the cleaning operation, the filter 13 is wound around the first pulley 11 together with the belt 10 and bypasses the outer periphery of the first pulley 11 so that the first filter position and the second filter position are changed. When the cleaning brush 17 is rotated, the surface of the filter 13 is scraped by the brush 19 of the cleaning brush 17, and the dust adhering to the surface of the filter 13 is removed. Scattered from the surface and collected in the dust box 20. As a result, the surface of the filter 13 is cleaned and its dust collecting function is regenerated. In this case, as shown in FIG. 4, since the rotation locus of the cleaning brush 17 overlaps with the tip end portion of the extension rib 20b provided in the dust bottom 20, the cleaning brush 17 At the time of rotation, the tip of the brush 19 comes into contact with the extending rib 20b, and dust adhering to the brush 19 side is scraped off. As a result, the scraping function of the brush 19 is regenerated. For example, dust scraped off by the brush 19 from the filter 13 side remains on the brush 19 side as it is and is cleaned on the already cleaned portion of the filter 13. Inconveniences such as reattachment are avoided.
ところで、上記ブラシ機構 Qにおいては、上記掃除ブラシ 17のブラシ 19によって上 記フィルタ 13側から搔き落としたゴミを上記ダストボックス 20内に捕集する力 S、このダ ストボックス 20内に捕集されたゴミの量が多くなると、このゴミが上記ケーシング 1とダ ストボックス 20の隙間から室内へ飛散して室内環境を悪化させる虞があることから、 その場合には、上記ダストボックス 20を上記収納部 30側から取り出してゴミを捨て、 再度、これを上記収納部 30に再装着するメンテナンス作業が必要となる。  By the way, in the brush mechanism Q, the force S for collecting the dust scraped off from the filter 13 side by the brush 19 of the cleaning brush 17 in the dust box 20 is collected in the dust box 20. If the amount of dust increases, the dust may scatter into the room from the gap between the casing 1 and the dust box 20 and deteriorate the indoor environment. It is necessary to carry out maintenance work to remove the dust from the 30 side, throw away the trash, and reinstall it in the storage unit 30 again.
[0029] しかし、このメンテナンス作業は、その実行タイミングが重要で、例えば、上記ダスト ボックス 20に溜まったゴミの量が少ない状態においてメンテナンス作業が頻繁に行な われると、該作業中は空調運転が停止されることから、空調の快適性が損なわれるこ とになる。また、逆に、上記ダストボックス 20内に多量のゴミがたまっているにも拘らず メンテナンス作業が行なわれな!/、と、ゴミの飛散による室内環境の悪化を招く等のこと は、既述の通りである。  [0029] However, the execution timing of this maintenance work is important. For example, if the maintenance work is frequently performed in a state where the amount of dust accumulated in the dust box 20 is small, air conditioning operation is performed during the work. Since it is stopped, the comfort of air conditioning is impaired. On the other hand, the maintenance work is not performed even though a large amount of dust is accumulated in the dust box 20, and the indoor environment is deteriorated due to the scattering of dust. Street.
そこで、この実施形態では、本願発明を適用して、上記ダストボックス 20内に溜まつ たゴミの量を適正に検知し、その量が予め設定したメンテナンス基準量に達したとき には、これを告知して、メンテナンス作業の実行を喚起するようにしている。  Therefore, in this embodiment, the present invention is applied to appropriately detect the amount of dust accumulated in the dust box 20 and notify when the amount reaches a preset maintenance reference amount. In order to encourage maintenance work.
ここで、このダストボックス 20のメンテナンスの告知制御の基本思想である力 この 実施形態では、  Here, the force that is the basic idea of the notice control of the maintenance of the dust box 20 In this embodiment,
(1)上記ダストボックス 20内のゴミの量の判断ロジックをより簡略化すべぐ該ダストボ ックス 20内のゴミの量を、上記掃除機構 Yの動作回数 (即ち、掃除運転の実行回数） によって判断する、  (1) The judgment logic of the amount of dust in the dust box 20 should be simplified. The amount of dust in the dust box 20 is judged by the number of operations of the cleaning mechanism Y (that is, the number of executions of the cleaning operation). ,
(2)上記ダストボックス 20内のゴミの量の判断と、メンテナンス基準量に基づくメンテ ナンス告知の判断との対応を明確にして、より簡略化された判断ロジックで正確にメ ンテナンス告知を行なうベぐメンテナンス基準量も、上記掃除機構 Yの動作回数で 規定する、 (2) Judgment of the amount of dust in the dust box 20 and maintenance based on the maintenance standard amount The maintenance reference amount for which maintenance notification is made accurately with a simplified decision logic with a clear correspondence with the nonce notification determination is also defined by the number of operations of the cleaning mechanism Y.
(3)上記掃除機構 Yの動作間隔と該掃除機構 Yの 1回の動作で上記ダストボックス 2 0側に捕集されるゴミの量との間の相関関係に着目し、上記ダストボックス 20内のゴミ の量をより精度良く検知すべぐ上記ダストボックス 20内のゴミの量の判断に際して、 上記掃除機構 Yの動作間隔 (即ち、掃除運転の頻度)を考慮する、  (3) Focusing on the correlation between the operation interval of the cleaning mechanism Y and the amount of dust collected on the dust box 20 side by one operation of the cleaning mechanism Y, the dust in the dust box 20 In determining the amount of dust in the dust box 20 to detect the amount of dust more accurately, the operation interval of the cleaning mechanism Y (i.e., the frequency of cleaning operation) is considered.
(4)掃除運転に対する使用者の要求に的確に対応して精度の良いメンテナンス告知 を実現すベぐ上記掃除機構 Yの動作間隔が複数設定される場合には、これら各動 作間隔に対応してメンテナンス基準量も複数設定する、  (4) When multiple operation intervals of the above cleaning mechanism Y are set to accurately respond to the user's request for the cleaning operation and realize accurate maintenance notification, it is necessary to correspond to each of these operation intervals. Set multiple maintenance reference amounts.
(5)上記掃除機構 Yの操作形態に対応したメンテナンス告知を実現すベぐメンテナ ンス基準量を、掃除運転が自動で定期的に行われる場合と、手動で不定期に行なわ れる場合とにおいて、異なる値に設定する、  (5) The maintenance reference amount that realizes the maintenance notice corresponding to the operation mode of the above cleaning mechanism Y is used when the cleaning operation is automatically performed periodically and when it is manually performed irregularly. Set to a different value,
ことをメンテナンス告知制御における基本思想としている。  This is the basic idea of maintenance notification control.
[0030] 以下、これらの基本思想の下での制御の実際を説明するが、それに先立って、先 ず、図 8を参照して、上記空気調和機 Zの制御系の構成を説明する。 [0030] Hereinafter, the actual control under these basic ideas will be described. Prior to that, the configuration of the control system of the air conditioner Z will be described with reference to FIG.
この空気調和機 Zでは、制御部として、室内機制御部 151と室外機制御部 152と空 調機構 Xを制御する空調機構制御部 153と掃除機構 Yを制御する掃除機構制御部 154と加湿 ·換気制御部 155を備えている。  In this air conditioner Z, as the control unit, an indoor unit control unit 151, an outdoor unit control unit 152, an air conditioning mechanism control unit 153 that controls the air conditioning mechanism X, a cleaning mechanism control unit 154 that controls the cleaning mechanism Y, and a humidifier A ventilation control unit 155 is provided.
上記室内機制御部 151には、空調運転制御部 151 aと掃除機構異常判定部 151b と掃除機構初期化処理部 151cとフィルタ掃除時期判定部 151dと掃除機構制御部 1 51eとダストボックスメンテナンス判定部 151fが設けられている。  The indoor unit control unit 151 includes an air conditioning operation control unit 151a, a cleaning mechanism abnormality determination unit 151b, a cleaning mechanism initialization processing unit 151c, a filter cleaning time determination unit 151d, a cleaning mechanism control unit 1 51e, and a dust box maintenance determination unit 151f. Is provided.
上記空調機構制御部 153には、前面パネル駆動部 153aと水平フラップ駆動部 15 3bと垂直フラップ駆動部 153cとファン駆動部 153dが設けられている。  The air conditioning mechanism control unit 153 is provided with a front panel drive unit 153a, a horizontal flap drive unit 153b, a vertical flap drive unit 153c, and a fan drive unit 153d.
[0031] 上記掃除機構制御部 154には、ブラシ駆動部 154aとフィルタ駆動部 154bとフィノレ タ位置検知部 154cとダストボックス検知部 154d及び掃除機構動作検知部 154eが 設けられている。 [0031] The cleaning mechanism control unit 154 includes a brush drive unit 154a, a filter drive unit 154b, a finisher position detection unit 154c, a dust box detection unit 154d, and a cleaning mechanism operation detection unit 154e.
また、上記室内機制御部 151は、リモコン 156と本体運転スィッチ 157によって操 作されるとともに、表示部 158とブザー 159及び遠隔操作装着 160が付設されている ここで、上記ダストボックス 20のメンテナンスとの関係でその制御が問題となるのは 、上記室内機制御部 151と上記掃除機構制御部 154の掃除機構動作検知部 154e 、表示部 158、ブザー 159及び遠隔操作装置 160であり、ここではこれらについての み説明し、これ以外の制御部の説明は省略する。 The indoor unit control unit 151 is operated by a remote controller 156 and a main body operation switch 157. The display unit 158, the buzzer 159, and the remote control mounting 160 are attached. Here, the control of the dust box 20 in relation to the maintenance is a problem. The cleaning mechanism operation detection unit 154e, the display unit 158, the buzzer 159, and the remote control device 160 of the cleaning mechanism control unit 154 will be described only here, and description of other control units will be omitted.
[0032] この実施形態では、上記掃除機構動作検知部 154eにおいて、掃除機構 Yの動作 回数を検知する。そして、上記室内機制御部 151の上記ダストボックスメンテナンス 判定部 151fでは、上記掃除機構動作検知部 154eからの動作回数信号を受け、そ の動作回数からダストボックス 20内に溜まっているゴミの量を判断し、このゴミの量とメ ンテナンス基準量に対応するゴミの量とを比較し、ダストボックス 20のメンテナンスが 必要な時期に至っているかどうかを判定する。即ち、この実施形態では、上記ダスト ボックスメンテナンス判定部 151fが、特許請求の範囲中の「判定手段」に該当する。 ここで、既にメンテナンスが必要な時期に至っていると判断された場合には、このこ と力 上記表示部 158における表示、上記ブザー 159での警報音、及び上記遠隔操 作装置 160への表示等によって、それぞれ告知される。即ち、この実施形態では、上 記表示部 158と上記ブザー 159及び上記遠隔操作装置 160が請求の範囲中の「告 知手段」に該当する。なお、この告知手段としては、上記表示部 158、上記ブザー 15 9及び上記遠隔操作装置 160の他に、例えば、双方向通信を行なうことができるワイ ャレスリモコンとかワイヤードリモコンを用いてこれらに表示、点灯等で告知することも 考えられる。 [0032] In this embodiment, the cleaning mechanism operation detector 154e detects the number of operations of the cleaning mechanism Y. The dust box maintenance determination unit 151f of the indoor unit control unit 151 receives the operation frequency signal from the cleaning mechanism operation detection unit 154e, and determines the amount of dust accumulated in the dust box 20 from the operation frequency. Then, compare the amount of dust with the amount of dust corresponding to the maintenance standard amount, and determine whether the dust box 20 needs maintenance. That is, in this embodiment, the dust box maintenance determination unit 151f corresponds to “determination means” in the claims. Here, if it is determined that the time when maintenance is necessary has been reached, this power is displayed on the display unit 158, an alarm sound on the buzzer 159, and a display on the remote control device 160. Respectively. That is, in this embodiment, the display unit 158, the buzzer 159, and the remote control device 160 correspond to “notification means” in the claims. As the notification means, in addition to the display unit 158, the buzzer 159, and the remote control device 160, for example, a wireless remote controller or a wired remote controller capable of two-way communication can be used to display and light on them. It is also possible to make a notice by such means.
[0033] このメンテナンス告知を受けた操作者は、上記ダストボックス 20のメンテナンス、即 ち、該ダストボックス 20を空気調和機 Z側から取外して、内部に溜まったゴミを捨て、 再度これを空気調和機 Zに装着する作業を行なう。  [0033] The operator who has received the maintenance notice performs maintenance of the dust box 20, that is, removes the dust box 20 from the air conditioner Z side, throws away the accumulated dust, and again removes the dust box 20 from the air conditioner Z. Work to attach to.
以上の制御を、図 9に示すフローチャートを参照して、より具体的に説明する。 制御開始後、先ずステップ S1において、掃除機構 Yの現時点までの累積動作回数 「Nt」を読み込む。次に、ステップ S2において、現在の掃除機構 Yの動作形態（即ち 、掃除運転の操作形態）が自動動作であるのか、手動動作であるのかを判定する。 ここで、自動動作とは、上記掃除機構 Yの掃除運転が定期的に自動で行なわれる ように設定された動作形態である。また、手動動作とは、操作者の手動操作によって 上記掃除機構 Yの掃除運転が不定期に行なわれるように設定された動作形態であるThe above control will be described more specifically with reference to the flowchart shown in FIG. After starting the control, first, in step S1, the cumulative number of operations “Nt” of the cleaning mechanism Y up to the present time is read. Next, in step S2, it is determined whether the current operation mode of the cleaning mechanism Y (that is, the operation mode of the cleaning operation) is an automatic operation or a manual operation. Here, the automatic operation is an operation mode set so that the cleaning operation of the cleaning mechanism Y is automatically performed periodically. The manual operation is an operation mode that is set so that the cleaning operation of the cleaning mechanism Y is performed irregularly by the manual operation of the operator.
。即ち、手動動作の場合には、定期的に操作者に対して掃除の奨励を告知はするが 、その告知を認識した操作者が自己の判断に基づいてリモコン操作等で掃除を実行 するものであるため、必ずしも定期的に掃除が行なわれるとは言えない。 . In other words, in the case of manual operation, the operator is periodically advised to encourage cleaning, but the operator who recognizes the notification performs cleaning by remote control operation based on his / her own judgment. For this reason, it cannot always be said that cleaning is performed regularly.
[0034] そして、自動動作の場合には、上記掃除機構 Yの 1回の動作で上記ダストボックス 2 0側に捕集されるゴミの量が比較的安定している力 手動動作の場合には、上記掃 除機構 Yの 1回の動作で上記ダストボックス 20側に捕集されるゴミの量は安定せず変 動し易い。  [0034] In the case of automatic operation, the force that the amount of dust collected on the dust box 20 side in a single operation of the cleaning mechanism Y is relatively stable. In the case of manual operation, The amount of dust collected on the dust box 20 side by one operation of the cleaning mechanism Y is not stable and easily changes.
そこで、ここでは、自動動作の場合と手動動作の場合におけるゴミの量の相違を考慮 して、 自動動作の場合におけるメンテナンス告知の判断基準と、手動動作の場合に おけるメンテナンス告知の判断基準を異ならせている。  Therefore, in consideration of the difference in the amount of dust between automatic operation and manual operation, the judgment criteria for maintenance notification in automatic operation are different from the judgment criteria for maintenance notification in manual operation. It is
ステップ S2において、現在は自動動作であると判断された場合であるが、この場合 には、先ず、ステップ S3において、メンテナンスを実行する基準となる掃除機構 Yの 動作回数 (即ち、メンテナンス基準量)を、予め設定された二つの値「Nal」、「Na2」 のうちから選択する。  In this case, it is determined that the automatic operation is currently performed in step S2.In this case, first, in step S3, the number of operations of the cleaning mechanism Y as a reference for performing maintenance (i.e., the reference amount of maintenance). Is selected from two preset values “Nal” and “Na2”.
[0035] ここで、このメンテナンスを実行する基準となる掃除機構 Yの動作回数、即ち、メン テナンス基準量となる掃除機構 Yの二つの動作回数「Nal」、「Na2」は、例えば、掃 除機構 Yの動作間隔に応じてそれぞれ設定されるもので、例えば、掃除機構 Yを 1日 1回動作させる場合における動作回数「Nal」と、掃除機構 Yを 1週に 1回動作させる 場合における動作回数「Na2」として設定されるものである。この場合、前者「Nal」は 、掃除運転の頻度が高ぐ上記掃除機構 Yの 1回の動作で捕集されるゴミの量が少な い場合の動作回数であり、後者「Na2」は、掃除運転の頻度が低ぐ上記掃除機構 Y の 1回の動作で捕集されるゴミの量が多い場合の動作回数であり、従って、これら両 者間には、「Nal > Na2」の関係がある。尚、後述する手動動作における動作回数 「Nbl」、「Nb2」も、上記自動動作の場合における動作回数「Nal」、「Na2」と同様 に、メンテナンス告知の間隔に基づ!/、て設定される。 [0036] 次に、ステップ S4において、選択された動作回数「Nal」又は「Na2」と上記累積動 作回数「Nt」を対比する。そして、 &1」又は &2」が、累積動作回数「Nt」に達し た場合には、メンテナンスの必要性が生じたと判断し、メンテナンスの必要性を告知 ーンし、次回の動作に備える。 [0035] Here, the number of operations of the cleaning mechanism Y serving as a reference for performing this maintenance, that is, the two operations “Nal” and “Na2” of the cleaning mechanism Y serving as a maintenance reference amount are, for example, For example, the number of operations “Nal” when the cleaning mechanism Y is operated once a day, and the operation when the cleaning mechanism Y is operated once a week. The number of times is set as “Na2”. In this case, the former “Nal” is the number of operations when the amount of dust collected by one operation of the cleaning mechanism Y is high, and the latter “Na2” is the cleaning frequency. This is the number of operations when the amount of garbage collected in one operation of the above cleaning mechanism Y is low, and therefore there is a relationship of “Nal> Na2” between the two. . Note that the number of manual operations (Nbl) and Nb2 in manual operation, which will be described later, is also set based on the maintenance notification interval, as in the case of the automatic operations (Nal) and (Na2). The Next, in step S4, the selected operation number “Nal” or “Na2” is compared with the cumulative operation number “Nt”. If & 1 ”or & 2” reaches the cumulative operation count “Nt”, it is determined that maintenance is necessary, and the need for maintenance is announced to prepare for the next operation.
これに対して、ステップ S4において、「Nal」又は「Na2」が、累積動作回数「Nt」に 達して!/、な!/、と判断される場合は、上記ダストボックス 20へのゴミの捕集が許容され る状態であるので、次にステップ S5で、その後、上記掃除機構 Yの掃除運転が実行 された力、どうかを判定し、掃除運転が実行された場合には、ステップ S6において累 積動作回数 1」を 1+ 1」とィンクリメントした後、ステップ S4にリターンする。そし て、「Nal」又は「Na2」が上記累積動作回数「Nt」に達するまで、制御を繰り返し (ス テツプ S4〜ステップ S6)、「Nal」又は「Na2」が、累積動作回数「Nt」に達した時点 で、メンテナンスの必要性を告知する (ステップ S 11)とともに、累積動作回数「Nt」を リセット (ステップ S 12)してリターンし、次回の動作に備える。  On the other hand, if “Nal” or “Na2” reaches the cumulative number of operations “Nt” in step S4 and is determined to be! /, NA! /, The collection of dust in the dust box 20 is performed. Next, in step S5, it is determined whether or not the cleaning mechanism Y is subjected to the cleaning operation, and if the cleaning operation is performed, the accumulation is performed in step S6. After incrementing operation count 1 ”to 1 + 1”, return to step S4. Then, the control is repeated until “Nal” or “Na2” reaches the cumulative operation number “Nt” (steps S4 to S6), and “Nal” or “Na2” becomes the cumulative operation number “Nt”. When it is reached, the necessity of maintenance is announced (Step S 11), and the accumulated operation count “Nt” is reset (Step S 12) and the process returns to prepare for the next operation.
[0037] ここで、ステップ S2において手動動作であると判断された場合の制御は、ステップ S 7における動作回数「Nbl」又は「Nb2」の値力 上述の自動動作の場合における動 作回数「Nal」又は「Na2」と異なるのみで、制御そのものは同じなので、自動動作の 場合の説明を援用し、ここでの説明を省略する。  [0037] Here, the control when it is determined that the manual operation is performed in step S2 is the value of the operation number "Nbl" or "Nb2" in step S7. The operation number "Nal" in the case of the automatic operation described above. ”Or“ Na2 ”, and the control itself is the same. Therefore, the explanation in the case of automatic operation is used, and the explanation here is omitted.
尚、自動動作の場合の動作間隔 (即ち、メンテナンス告知の間隔)と、手動動作の 場合のメンテナンス告知の間隔を同じに設定した場合でも、自動動作時の動作回数 「Na 1」と手動動作時の動作回数「Nb 1」、又は自動動作時の動作回数「Na2」と手動 動作時の動作回数「Nb2」は、「Nal〉Nbl」、「Na2〉Nb2」となるように設定される 。これは、自動動作の場合はメンテナンス告知の都度、定期的に掃除運転が行なわ れるので 1回の掃除運転当りのゴミの量は少ないが、手動動作の場合は上述のように 必ずしもメンテナンス告知の都度掃除運転が行なわれるものではないため 1回の掃 除運転当りのゴミの量は、 自動動作の場合よりも多いものと考えられるからである。  Even if the operation interval for automatic operation (i.e., the interval for maintenance notification) and the interval for maintenance notification for manual operation are set to be the same, the number of operations during automatic operation `` Na 1 '' and manual operation The number of operations “Nb 1” or the number of operations “Na2” during automatic operation and the number of operations “Nb2” during manual operation are set to be “Nal> Nbl” and “Na2> Nb2”. This is because the cleaning operation is regularly performed every time the maintenance operation is notified in the automatic operation, so the amount of dust per cleaning operation is small. However, in the case of the manual operation, as described above, the maintenance operation is not always performed. This is because the cleaning operation is not performed, so the amount of garbage per cleaning operation is considered to be larger than in the automatic operation.
[0038] 以上のように、この実施形態のメンテナンス制御によれば、上記ダストボックス 20に 溜まるゴミの量を判断しその量が予め設定されたメンテナンス基準量に達したときメン テナンス信号を出力するとともに、このメンテナンス信号を受けて上記ダストボックス 2 0のメンテナンスを告知し、操作者のメンテナンスの実行を喚起するものであることか ら、例えば、従来のように、空調運転の運転積算時間からフィルタに溜まったゴミの量 を推測し、これに基づいてダストボックスのメンテナンスを告知する構成のように、フィ ルタの掃除頻度の高低による不適切な判断が生じず、ダストボックス 20のメンテナン スの告知をより適切なタイミングで行なうことができ、その結果、不必要なメンテナンス の実行に伴い空調運転が停止されることによる室内空調の快適性の低下とか、ダスト ボックス 20にゴミが過度に溜まってゴミが室内へ飛散することによる室内環境の悪化 等が防止され、それだけ空気調和機の性能特性の向上が期待できるものである。 尚、上記実施形態では、壁掛型の空気調和機（室内機）を例にとって説明したが、 本願発明はこれに限定されるものではなぐ例えば、天井埋込型、床置型等の空気 調和機にも適用できることは言うまでも無い。 As described above, according to the maintenance control of this embodiment, the amount of dust accumulated in the dust box 20 is determined, and when the amount reaches a preset maintenance reference amount, the maintenance is performed. In addition to outputting a tenance signal and receiving this maintenance signal, the maintenance of the dust box 20 is notified and the operator performs maintenance. Maintenance of the dust box 20 without making inappropriate judgments due to the frequency of cleaning the filter, unlike the configuration in which the dust box maintenance is informed based on the estimated amount of dust accumulated in the accumulated time. As a result, the air conditioning operation is stopped due to unnecessary maintenance, resulting in a decrease in the comfort of indoor air conditioning or excessive accumulation of dust in the dust box 20. Therefore, the air conditioner's performance can be prevented by preventing the indoor environment from deteriorating due to dust scattering inside the room. One in which sexual improvement can be expected. In the above embodiment, a wall-mounted air conditioner (indoor unit) has been described as an example. However, the present invention is not limited to this, for example, an air conditioner such as a ceiling-embedded type or a floor-mounted type. It goes without saying that can also be applied.
