Description
本発明は室内機と室外機とに分離した壁掛け型エアーコンディショナー（以下、エアコンと略す）の室内機を洗浄するための洗浄カバー及び洗浄方法に関する。 The present invention relates to a cleaning cover and a cleaning method for cleaning an indoor unit of a wall-mounted air conditioner (hereinafter abbreviated as an air conditioner) separated into an indoor unit and an outdoor unit.
エアコンの熱交換機アルミフィン（以下、アルミフィンと略す）や送風ファンの洗浄は室内機の前面パネルを取り外して行われる。これらの洗浄についての特許を発明者らは、すでに登録（特許文献１）している。 The air conditioner heat exchanger aluminum fin (hereinafter abbreviated as “aluminum fin”) and the blower fan are cleaned by removing the front panel of the indoor unit. The inventors have already registered patents for these cleanings (Patent Document 1).
以下、特許文献１の図１により背景技術を説明する。
図１の洗浄装置は室内機の全体を包み込む軟質防水性の洗浄カバー１と、排水ホース５により当該洗浄カバー１の下部１ｄに接続されて洗浄後の廃液を受ける廃液回収容器１２と、異なる洗浄液を貯える少なくとも2つの洗浄液容器１０，１１と、分岐水栓７及び洗浄ポンプ６を介して一つの洗浄液容器内の洗浄液を当該洗浄カバーの正面（以下、正面という）の洗浄ノズル３の挿入孔１ａを通して前記室内機に洗浄薬液を噴射する洗浄ノズル３と、制御回路８を介してポンプ及び分岐水栓を作動するコントローラ４を含み該コントローラ４は該ノズル３に備えられていることを特徴としている。
The background art will be described below with reference to FIG.
The cleaning apparatus in FIG. 1 is different from a soft and waterproof cleaning cover 1 that wraps the whole indoor unit, and a waste liquid collection container 12 that is connected to the lower part 1d of the cleaning cover 1 by a drain hose 5 and receives waste liquid after cleaning. The cleaning liquid in one cleaning liquid container through at least two cleaning liquid containers 10 and 11 and the branch water tap 7 and the cleaning pump 6 are inserted into the insertion hole 1a of the cleaning nozzle 3 in front of the cleaning cover (hereinafter referred to as the front). And a controller 4 for operating a pump and a branch faucet via a control circuit 8 and the controller 4 is provided in the nozzle 3. .
上記以外のエアコンの洗浄カバー及び洗浄方法に関するものは、特許文献２，特許文献３などが出願されている。いずれの特許も、洗浄カバーを使用してエアコン室内機の全体を包み込み、設置した状態で洗浄し、廃液を漏れることなく回収容器に回収することを特徴にしている。 Patent documents 2, 3 and the like have been applied for air conditioner cleaning covers and cleaning methods other than those described above. Both patents are characterized in that the entire air conditioner indoor unit is wrapped using a cleaning cover, cleaned in an installed state, and the waste liquid is recovered in a recovery container without leaking.
特許文献２では、室内機全体を包み込む洗浄カバーを使用して、洗浄カバーの前面に設けた孔、当該孔に洗浄機ノズルを挿入して、アルミフィン及び送風ファンを洗浄、その廃液を洗浄カバー下部の排水ホースから回収する構成を特徴としている。 In Patent Document 2, a cleaning cover that wraps the whole indoor unit is used, a hole provided on the front surface of the cleaning cover, a cleaning machine nozzle is inserted into the hole, the aluminum fin and the blower fan are cleaned, and the waste liquid is cleaned. It is characterized by the structure of collecting from the lower drainage hose.
特許文献３では、エアコン室内機背面の筐体を利用して箱型の枠を組み付け、枠組みを利用してビニールシートで室内機全体を包み込むことを特徴にした洗浄カバー及び洗浄方法である。 Patent Document 3 discloses a cleaning cover and a cleaning method characterized in that a box-shaped frame is assembled using a casing on the back of an air conditioner indoor unit, and the entire indoor unit is wrapped with a vinyl sheet using the frame.
いずれの特許も室内機全体を覆う、軟質防水性の洗浄カバーを考案して、室内機の前面からアルミフィンと送風ファンを洗浄する方法である。 Both patents devise a soft waterproof cleaning cover that covers the entire indoor unit, and cleans the aluminum fins and the blower fan from the front of the indoor unit.
住宅の多様化に伴う生活者のエアコン室内機へのコンパクト化の要請に沿って、エアコン室内機の外観及び内部のアルミフィン、送風ファン等の形状は、約２０年前から大きく変化してきている。
住宅の多様化に合わせて、どこにでも設置できるように、エアコン室内機はより小型化、コンパクトなデザインとなっている。
もう一つのエアコンの商品化の時流として、エアコンの消費電力を低減する省エネルギーの課題がある。
省エネルギーの課題を解決するには、アルミフィンの面積を大きくするあるいはアルミニウムより熱伝導率の良い材料で熱交換器を形成する方法がある。
コンパクト化と省エネルギーの相反する条件を満たしたエアコン室内機を商品化するために、エアコンメーカ各社が採用した手段は、次の２つである。
（１）コンパクト化を実現するために、エアコン室内機の高さは従来よりも約１００ｍｍ程度小さい形状となっている。従来の標準的な高さ３６０ｍｍ標準が、２６０ｍｍ程度の高さと小さくなっている。アルミフィンを山形に折り曲げて後方に１００ｍｍ程度を移動する形状の室内機。
（２）アルミフィンの隙間（ピッチ）を約５０％に狭めてアルミフィンの枚数を増加、アルミフィンの面積を大きくした室内機の採用で省エネルギー化を実現。
In line with the diversification of homes, the exterior of air conditioner indoor units and the shape of internal aluminum fins, blower fans, etc. have changed significantly since about 20 years ago in line with the demand for compactness of air conditioner indoor units. .
The air conditioner indoor unit has been made smaller and more compact so that it can be installed anywhere in accordance with the diversification of houses.
Another trend in commercialization of air conditioners is the problem of energy saving to reduce the power consumption of air conditioners.
In order to solve the problem of energy saving, there are methods of increasing the area of the aluminum fins or forming the heat exchanger with a material having better thermal conductivity than aluminum.
In order to commercialize air conditioner indoor units that satisfy the contradictory conditions of compactness and energy saving, air conditioner manufacturers have adopted the following two methods.
(1) In order to achieve compactness, the height of the air conditioner indoor unit is about 100 mm smaller than the conventional one. The conventional standard height 360 mm standard is as small as about 260 mm. An indoor unit that has a shape in which aluminum fins are bent into a chevron and moved about 100 mm backward.
(2) The gap (pitch) between aluminum fins is reduced to about 50%, the number of aluminum fins is increased, and energy saving is achieved by adopting an indoor unit with a larger aluminum fin area.
このようなコンパクト室内機の出現に伴い、副作用としてアルミフィンの汚れる速度が速くなり、カビ汚染も酷くなり、２〜3年周期で室内機を洗浄しないと使用できない室内機となっている。
これらの課題の対応策として、エアコンメーカ各社が１０余年前に考案、商品化したのがフィルター自動清掃機構を備えた壁掛け型エアコン（以下、おそうじ機構付エアコンと略す）である。
With the advent of such compact indoor units, as a side effect, the rate at which aluminum fins get dirty increases, mold contamination becomes severe, and the indoor units cannot be used unless the indoor units are washed every two to three years.
As countermeasures against these problems, air conditioner manufacturers invented and commercialized over 10 years ago is a wall-mounted air conditioner equipped with an automatic filter cleaning mechanism (hereinafter abbreviated as an air conditioner with a cleaning mechanism).
図２は、エアコンメーカ7社のカタログに掲載されている、おそうじ機構付エアコンのイメージ図である。２１がおそうじ機構部を示す。
エアコンの各メーカは、おそうじ機構付エアコンを生産しているが、統一された構造はなく各社各様の構造となっている。
おそうじ機構付エアコンは、図２に示すように各社共に当該機構部２１が室内機のアルミフィン前面を覆う形状で出来ているので、当該機構を取外さないとアルミフィンはきれいに洗浄できない課題がある。
しかし、取り外すには、おそうじ機構のフィルター駆動部あるいはゴミ吸い取り部のモーターへの配線が繋がっているコネクターを制御基盤（殆ど右側に設置されている）から抜き取る必要がある。
コネクターを外せても、数十本ある配線が本体に這わせてあるのでおそうじ機構を外すには、当該機構を分解する相応の訓練が必要である。
これらの分解、洗浄作業を行うには、おそうじ機構付のない従来機種に比べて、多大な働力と
分解に要する2〜3倍の時間が必要となっている課題がある。
また、制御基板は、右側に設置している場合がほとんどであるので、右側に壁がある場合は、
制御基板のボックス３３からコネクターを抜けない場合が多い。
結果として、最近のおそうじ機構付エアコンのクリーニングは、従来機種に比べて、2〜3倍の時間と費用がかかり、トラブルのリスクの高いエアコンクリーニング作業となっている課題がある。
FIG. 2 is an image diagram of an air conditioner with a cleansing mechanism, which is published in the catalogs of seven air conditioner manufacturers. Reference numeral 21 denotes a cleaning mechanism.
Each manufacturer of air conditioners produces air conditioners with cleansing mechanisms, but there is no unified structure and each company has its own structure.
As shown in FIG. 2, the air conditioner with a cleansing mechanism is made in such a manner that the mechanism portion 21 covers the front surface of the aluminum fin of the indoor unit in each company. .
However, in order to remove the connector, it is necessary to remove the connector connected to the motor of the filter drive part or dust suction part of the cleaning mechanism from the control board (mostly installed on the right side).
Even if the connector can be removed, dozens of wires are routed on the main body, so removing the cleaning mechanism requires appropriate training to disassemble the mechanism.
In order to perform these disassembly and cleaning operations, there is a problem that it requires a great work force and two to three times the time required for disassembly as compared with a conventional model without a cleaning mechanism.
Also, the control board is mostly installed on the right side, so if there is a wall on the right side,
In many cases, the connector cannot be removed from the box 33 of the control board.
As a result, the recent cleaning of the air conditioner with a cleaning mechanism takes two to three times as much time and cost as the conventional model, and there is a problem that the cleaning of the air conditioner has a high risk of trouble.
本発明では、上記の課題を克服した形状の洗浄カバーを考案して、アルミフィンの前面と背面
（壁側の奥の面）の両面及び送風ファンを容易に洗浄できる新規な洗浄カバーを提供するにある。さらに、おそうじ機構を本体室内機から完全に取り外すことなく、本体のアルミフィンから ５０〜１００ｍｍ程度おそうじ機構を浮かせるアダプターを考案、取り外してクリーニングしたのと同程度の洗浄力と同等程度の作業時間で洗浄を行う方法を提供するにある。
In the present invention, a cleaning cover having a shape that overcomes the above problems is devised to provide a novel cleaning cover that can easily clean both the front and back surfaces of the aluminum fins (the back surface on the wall side) and the blower fan. It is in. Furthermore, without completely removing the cleaning mechanism from the indoor unit of the main unit, an adapter that lifts the cleaning mechanism from the aluminum fin of the main unit by about 50 to 100 mm was devised. It is in providing the method of performing washing.
要点を説明すると、アルミフィンの背面を洗浄できるようにするためには、アルミフィンの上面から背面に向けて、洗浄ノズルを操作できる空間を設ける必要がある。
本発明では、特許文献１に示した密閉型の洗浄カバーは採用せず、下部を漏斗状、すなわち上面を開放形に設計する。さらに上面解放形下部漏斗状の洗浄カバーを短時間にセットできる洗浄カバーの保持具を新規に考案した。
To explain the point, in order to be able to clean the back surface of the aluminum fin, it is necessary to provide a space in which the cleaning nozzle can be operated from the top surface to the back surface of the aluminum fin.
In the present invention, the hermetic cleaning cover shown in Patent Document 1 is not adopted, and the lower portion is designed in a funnel shape, that is, the upper surface is designed in an open shape. In addition, we have devised a new cleaning cover holder that can set the upper open type lower funnel-shaped cleaning cover in a short time.
おそうじ機構付エアコンを本体から取り外さないで、本体から浮かせるための治具として、細長い風船形のビニール樹脂製のエアークッションを考案、室内機本体アルミフィンとおそうじ機構の間にエアークッション挿入、５０〜１００ｍｍ程度の隙間を形成することにより従来と同様な洗浄が可能となる。 As a jig to lift the air conditioner equipped with the cleansing mechanism from the main unit, a long balloon-shaped vinyl resin air cushion was devised. Inserted the air cushion between the indoor unit main body aluminum fin and the cleansing mechanism, 50 ~ By forming a gap of about 100 mm, it is possible to perform cleaning similar to the conventional case.
上記したように本発明では、上面解放形下部漏斗状の洗浄カバーを考案、加えて当該洗浄カバーを簡単に室内機に装着できる洗浄カバーの保持具を考案、さらにおそうじ機構を本体アルミフィンから浮かせるための治具として、細長形状のビニール製のエアークションを考案したことにより、従来と同等程度の作業時間及び洗浄能力で完了する洗浄方法となる効果がある。 As described above, in the present invention, an upper open-type lower funnel-shaped cleaning cover is devised, in addition, a cleaning cover holder that can be easily attached to the indoor unit is devised, and the cleaning mechanism is further lifted from the main body aluminum fin. By devising an elongated vinyl aeration as a jig for this purpose, there is an effect of a cleaning method that can be completed with a working time and a cleaning capability comparable to the conventional one.
