Description

本発明は、メンテナンスを必要としない空気調和機に関する。   The present invention relates to an air conditioner that does not require maintenance.

従来の空気調和機は、付加機能装置として持つ電気集塵装置、濾過式集塵装置、脱臭手段、イオン発生手段等の部品について、数カ月から３年程度で交換や掃除が必要なものを持っていることがある上に、プレフィルタは２週間程度で掃除が必要であり、熱交換器や送風ファン、空気通路もごみや菌による臭いや性能低下が生じることがあり、専門業者による清掃を必要とする場合もあった。本明細書ではこれらの作業を総称してメンテナンスとして以下の説明を行う。また、特にユーザーが行えるメンテナンスをユーザーメンテナンスと称する。   Conventional air conditioners have components that require replacement or cleaning in a few months to 3 years, such as electric dust collectors, filtration dust collectors, deodorizing means, and ion generating means as additional function devices. In addition, the pre-filter needs to be cleaned in about two weeks, and the heat exchanger, blower fan, and air passage may be odor and performance degradation due to dust and bacteria, and needs cleaning by a specialist. There was also a case. In the present specification, these operations are collectively referred to as maintenance as follows. In particular, maintenance that can be performed by the user is referred to as user maintenance.

上記のメンテナンスは、面倒であったり、費用がかかる上に、放置しておくと機器の本来の機能を享受できない。   The above maintenance is cumbersome and expensive, and if it is left unattended, the original functions of the device cannot be enjoyed.

そのために様々な対策が講じられているが、例えばプレフィルタに関しては、図５のようなプレフィルタの清掃装置付き空気調和機の発明、考案がなされている（例えば特許文献１参照）。   For this purpose, various countermeasures have been taken. For example, regarding a prefilter, an invention and an invention of an air conditioner with a prefilter cleaning device as shown in FIG. 5 have been made (for example, see Patent Document 1).

この従来例は、本体の前面上部および上面に設けられた吸込口２と、前面下部に設けられた吹出口３とを結ぶ空気通路に、プレフィルタ４と、熱交換器６と、送風ファン５とを夫々設けた構成の空気調和機において、前記プレフィルタ４を清掃するためにプレフィルタ４上を移動自在に形成されたフィルタ清掃装置９を設けるが、このフィルタ清掃装置９は、プレフィルタ４をフィルタ清掃装置９の内側に沿って回動させる回動手段１０と、プレフィルタ４上のごみを除去するごみ除去手段１１と、ごみを収納するごみ収納部１２から構成されている。   In this conventional example, a pre-filter 4, a heat exchanger 6, and a blower fan 5 are connected to an air passage that connects a suction port 2 provided at the upper front and upper surfaces of the main body and a blower outlet 3 provided at the lower front. In order to clean the pre-filter 4, a filter cleaning device 9 that is movably formed on the pre-filter 4 is provided. The filter cleaning device 9 is provided with the pre-filter 4. It is comprised from the rotation means 10 which rotates along the inside of the filter cleaning apparatus 9, the dust removal means 11 which removes the dust on the pre-filter 4, and the waste storage part 12 which stores waste.

以上の構成により、このフィルタ清掃装置９はプレフィルタ４上を移動するにつれ、プレフィルタ４上に付着したごみは吸引され、ごみ収納部１２に運ばれる。また、フィルタ清掃装置９が左右に移動するとともに、プレフィルタ４が前記回動手段１０によってそれと直角方向に移動されるので、前記プレフィルタ４のほぼ全部の面積についてごみを吸引することができるというものである。
特開２００２−３４０３９５号公報 With the above configuration, as the filter cleaning device 9 moves on the prefilter 4, dust adhering to the prefilter 4 is sucked and carried to the dust container 12. In addition, the filter cleaning device 9 moves to the left and right, and the prefilter 4 is moved in the direction perpendicular to the rotation means 10, so that dust can be sucked in almost the entire area of the prefilter 4.

しかしながら、前記従来の構成では、プレフィルタに関しては、メンテナンスが不要にできるものの、前述のように付加機能装置にメンテナンスが必要なものがひとつでもある場合、空気調和機のメンテナンスはなくならないという課題を有していた。   However, in the conventional configuration, although the maintenance for the prefilter can be made unnecessary, the maintenance of the air conditioner is not lost when the additional function device requires maintenance as described above. Had.

また、熱交換器、送風ファン、空気通路については、使用条件によってはメンテナンスが必要になることもあった。   In addition, the heat exchanger, the blower fan, and the air passage may require maintenance depending on use conditions.

このようなメンテナンスは少なければ少ないほど良いが、わずかであっても必要な場合と、全く不要という場合の差はユーザーにとって非常に大きい差である。   The smaller the maintenance, the better, but the difference between when it is necessary and when it is completely unnecessary is very large for the user.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は、本発明の第一の実施の形態における空気調和機の縦断面図、図２は空気調和機のフィルタ自動清掃機能を説明する斜視図、図３は本発明の概念を説明する説明図である。 (Embodiment 1)
FIG. 1 is a longitudinal sectional view of an air conditioner according to a first embodiment of the present invention, FIG. 2 is a perspective view illustrating an automatic filter cleaning function of the air conditioner, and FIG. 3 is an explanatory diagram illustrating the concept of the present invention. FIG.

図１、２において、１は本発明による空気調和機本体、２は同本体１の前面から上面にかけて設けられた吸込口、３は前記本体１の下部に設けられた吹出口である。   1 and 2, reference numeral 1 denotes an air conditioner main body according to the present invention, 2 denotes a suction port provided from the front surface to the upper surface of the main body 1, and 3 denotes an air outlet provided at a lower portion of the main body 1.

前記吸込口２と、前記吹出口３とを結ぶ空気通路には、空気中の大きいごみを取り除くプレフィルタ４と、ファンモータ８に連係された送風ファン５と、熱交換器６とが設けられている。   A prefilter 4 that removes large dust in the air, a blower fan 5 linked to a fan motor 8, and a heat exchanger 6 are provided in an air passage that connects the suction port 2 and the blowout port 3. ing.

前記プレフィルタ４と熱交換器６の間には脱臭フィルタ１１３があり、前記吹出口３内にはイオン生成装置１１４がある。   A deodorizing filter 113 is provided between the prefilter 4 and the heat exchanger 6, and an ion generating device 114 is provided in the outlet 3.

また、フィルタ４に沿って上下方向に帯状形状をして左右方向に移動可能で、プレフィルタ面側に吸引口１１８とブラシ１１９を有するノズル１１５があり、左方にあるごみ排出ファン１１６とは吸引ダクト１１７で接続されている。   In addition, a belt-like shape is formed in the vertical direction along the filter 4 and can be moved in the horizontal direction. There is a nozzle 115 having a suction port 118 and a brush 119 on the prefilter surface side. They are connected by a suction duct 117.

前記熱交換器６のフィンには防菌防黴剤ジンクピリチオンの混ざった表面処理剤が塗布されている。   The fins of the heat exchanger 6 are coated with a surface treatment agent mixed with antibacterial and antifungal agent zinc pyrithione.

また、送風ファン５と空気通路１０７の樹脂にもベンツイミダソール系抗菌剤の混ざった塗料が塗布されている。   Further, a paint mixed with a benzimidazole antibacterial agent is also applied to the resin of the blower fan 5 and the air passage 107.

以上のように形成されたことによって、本発明による空気調和機は次のように作用する。なお、本発明の趣旨は空気調和機全体としての機能に関するものであるため、個々の機能に関する説明は、骨子のみの説明にとどめる。   By being formed as described above, the air conditioner according to the present invention operates as follows. In addition, since the meaning of this invention is related with the function as the whole air conditioner, the description regarding each function is only the description of only the main point.

まず、大きいごみを捕捉して、内部の熱交換器６等を保護するプレフィルタ４について説明する。   First, the prefilter 4 that captures large dust and protects the internal heat exchanger 6 and the like will be described.

ごみ排出ファン１１６が駆動すると、ノズル１１５の吸引口１１８からプレフィルタ面上のごみが吸引清掃され、吸引ダクト１１７、ごみ排出ファン１１６を通過して屋外に排出される。   When the dust discharge fan 116 is driven, the dust on the prefilter surface is sucked and cleaned from the suction port 118 of the nozzle 115, passes through the suction duct 117 and the dust discharge fan 116, and is discharged outdoors.

さらに、ノズル１１５が左右に移動することで、プレフィルタ４の全面が掃除されるとともに、ブラシ１１９により、より確実完全に掃除がされる。   Furthermore, as the nozzle 115 moves to the left and right, the entire surface of the pre-filter 4 is cleaned, and the brush 119 is more reliably and completely cleaned.

以上のような作用でプレフィルタ４に関してのメンテナンスが不要となる。   The maintenance regarding the prefilter 4 becomes unnecessary by the above operations.

次に、微小な塵埃に対する集塵手段である電気集塵装置について説明する。   Next, an electric dust collector that is dust collecting means for minute dust will be described.

一般の電気集塵装置の場合、荷電部と集塵部からなり、荷電部で塵埃を帯電させ、集塵部に付着させやすくして効率良く集塵するが、荷電部、集塵部ともにごみが溜まったり、微粒子の付着により汚れがひどくなると、掃除や水洗い等のメンテナンスが必要になる。   A general electrostatic precipitator consists of a charging unit and a dust collecting unit. The charging unit charges the dust and makes it easy to attach to the dust collecting unit for efficient dust collection. If dirt accumulates due to adhesion of fine particles, maintenance such as cleaning and washing becomes necessary.

本実施例では、イオン生成装置１１４が電極に高電位を付与することで、空気中の塵埃を帯電させる荷電部に相当するが、イオン生成装置１１４はプレフィルタ４や熱交換器６の下流にあり、通過空気に大きいごみを含まないため掃除を必要としない。   In the present embodiment, the ion generator 114 applies a high potential to the electrode, which corresponds to a charging unit that charges dust in the air. However, the ion generator 114 is disposed downstream of the prefilter 4 and the heat exchanger 6. There is no need for cleaning because it does not contain large garbage in the passing air.

また、プレフィルタ４が、帯電した塵埃を付着させる集塵部の働きをするが、前述したようにプレフィルタ４は自動的に掃除される。   In addition, the prefilter 4 functions as a dust collecting unit for adhering charged dust, but the prefilter 4 is automatically cleaned as described above.

以上のような作用で微小な塵埃に対する集塵手段である電気集塵装置に関してのメンテナンスが不要となる。   The above operation eliminates the need for maintenance on the electric dust collector, which is a dust collecting means for minute dust.

なお、微小な塵埃に対する集塵手段としては、プレフィルタによる濾過式集塵装置を用いることも考えられるが、この場合もプレフィルタ４の一部を微小塵埃用のフィルタとすることで、自動的に掃除することで、メンテナンスを不要とできる。   As a dust collecting means for minute dust, it is conceivable to use a pre-filter filtration type dust collector, but in this case as well, a part of the pre-filter 4 is used as a filter for minute dust. By cleaning it, maintenance can be made unnecessary.

次に、脱臭手段である脱臭フィルタ１１３について説明する。   Next, the deodorizing filter 113 which is a deodorizing means will be described.

一般に脱臭手段は、臭い分子を捕捉するコレクターが飽和すると、脱臭機能を失うため当該脱臭手段を交換する必要がある。   In general, the deodorizing means loses its deodorizing function when the collector that captures odorous molecules is saturated, and thus the deodorizing means needs to be replaced.

本実施例の脱臭フィルタ１１３では、捕捉した臭い分子（アルデヒド）を通気で脱着可能な成分（酢酸）に化学的に変化させる触媒であるコバルト酸化物を担持することで、半永久的にコレクター（ゼオライト）が飽和しないため、交換の必要がなくなる。   In the deodorizing filter 113 of this embodiment, the collector (zeolite) is semipermanently supported by supporting cobalt oxide, which is a catalyst that chemically changes the trapped odor molecule (aldehyde) into a component (acetic acid) that can be desorbed by ventilation. ) Does not saturate and need not be replaced.

以上のような作用で脱臭手段である脱臭フィルタ１１３に関してのメンテナンスが不要となる。   The above operation eliminates the need for maintenance on the deodorizing filter 113 which is a deodorizing means.

次に、イオン発生手段について説明する。   Next, the ion generating means will be described.

本実施例では、イオン生成装置１１４がマイナスイオンを発生するイオン発生手段でもあり、当該イオン生成装置１１４の生成するイオンを、空気調和機の吹出し風に乗せて室内に放出することにより、イオンの働きで菌やアレルゲンを不活化することができる。また、前記イオンにより菌やアレルゲンに電荷を帯びさせ、プレフィルタ４での捕捉効率を向上することもできる。   In this embodiment, the ion generation device 114 is also an ion generation means for generating negative ions, and the ions generated by the ion generation device 114 are discharged into the room on the air blower of the air conditioner, thereby generating ions. The function can inactivate bacteria and allergens. In addition, it is possible to improve the capture efficiency of the prefilter 4 by charging the bacteria and allergen with the ions.

電気集塵装置の項で前述したようにイオン生成装置１１４については掃除が不要であるため、イオン発生手段に関してもメンテナンスは不要である。   As described above in the section of the electrostatic precipitator, the ion generator 114 does not need to be cleaned, so that no maintenance is required for the ion generating means.

以上、作用を説明してきた電気集塵装置、濾過式集塵装置、脱臭手段、イオン発生手段は、従来から空気調和機に必須の機能である冷房や暖房と異なり、空気調和機に必ず備わっている機能ではない。したがって、本明細書では、これらを総称して付加機能装置と呼称する。   The electric dust collector, filtering dust collector, deodorizing means, and ion generating means, which have been described above, are always provided in the air conditioner, unlike the cooling and heating functions that are conventionally required for an air conditioner. It is not a function. Therefore, in this specification, these are collectively referred to as an additional function device.

これに対し、最初に説明したプレフィルタ４及び以下に説明する熱交換器６、送風ファン５、空気通路１０７は空気調和機の必須の構成要素であり、一般にはメンテナンスを必要とする付加機能装置とは異なり、プレフィルタ４以外は必ずしもメンテナンスをしなくとも良いとされてきた。   On the other hand, the prefilter 4 described first, the heat exchanger 6, the blower fan 5, and the air passage 107 described below are essential components of the air conditioner, and generally an additional function device requiring maintenance. Unlike the pre-filter 4, it has not been necessary to perform maintenance.

したがって、プレフィルタ４と付加機能装置の総てをメンテナンス不要とすることにより、一般的には、ユーザーはメンテナンスに全く留意することなく、機器が本来持つ機能を低下することなく使用できる。   Therefore, by making the prefilter 4 and all of the additional function devices maintenance-free, generally, the user can use the device without degrading the original function without paying attention to maintenance.

しかし、近年になって、空気調和機内部の熱交換器６、送風ファン５、空気通路１０７の汚れや臭いに対して不快感を持つユーザーも増加しており、そのような場合には、専門業者による清掃が行われている。   However, in recent years, an increasing number of users feel uncomfortable with the dirt and odor of the heat exchanger 6, the blower fan 5, and the air passage 107 inside the air conditioner. Cleaning is performed by a contractor.

そこで、本実施例による熱交換器６について説明する。   Therefore, the heat exchanger 6 according to this embodiment will be described.

本実施例の熱交換器６のフィンには防菌防黴剤ジンクピリチオンの混ざった表面処理剤が塗布されている。冷房時、フィンの表面が濡れると、防菌防黴剤ジンクピリチオンが表面処理剤内部から溶出して、フィン表面に付着したごみ、湿分によって繁殖するカビや菌に働き、これらカビや菌が生成する汚れや臭いを抑制して、フィン表面を清潔に維持する。   A surface treatment agent mixed with antibacterial and antifungal agent zinc pyrithione is applied to the fins of the heat exchanger 6 of this embodiment. When the fin surface gets wet during cooling, the antibacterial and fungicidal agent zinc pyrithione elutes from inside the surface treatment agent and acts on the mold and fungus that grow on the dust and moisture attached to the fin surface. Suppresses dirt and odors and keeps the fin surface clean.

また、詳細な説明は省略するが、防菌防黴剤や、表面処理剤の組成、量を適切に選定することで、防菌防黴効果の持続期間を調整することが可能である。   Moreover, although detailed description is abbreviate | omitted, it is possible to adjust the duration of an antibacterial and antifungal effect by selecting appropriately the composition and quantity of an antibacterial and antifungal agent and a surface treating agent.

以上のような作用で熱交換器６に関してのメンテナンスが不要となる。   The maintenance regarding the heat exchanger 6 becomes unnecessary by the above operations.

次に、送風ファン５と空気通路１０７について説明する。   Next, the blower fan 5 and the air passage 107 will be described.

本発明の送風ファン５と空気通路１０７の樹脂材料にもベンツイミダソール系防菌防黴剤の混ざった塗料が塗布されている。一般には、冷房時、送風ファン５と空気通路１０７は高湿の空気に曝されるため、表面あるいは表面に付着したごみにカビや菌が繁殖することがあるが、本実施例では、これらに防菌防黴剤が働くため、これらカビや菌が生成する汚れや臭いを抑制して、送風ファン５と空気通路１０７を清潔に維持する。   The resin material of the blower fan 5 and the air passage 107 of the present invention is also coated with a paint mixed with a benzimidazole antibacterial and antifungal agent. In general, during cooling, since the blower fan 5 and the air passage 107 are exposed to high humidity air, mold and fungi may propagate on the surface or on the dust attached to the surface. Since the antibacterial and antifungal agent works, the blower fan 5 and the air passage 107 are kept clean by suppressing dirt and odor generated by these molds and fungi.

また、詳細な説明は省略するが、防菌防黴剤や、塗料の組成、量を適切に選定することで、防菌防黴効果の持続期間を調整することが可能である。   Moreover, although detailed description is abbreviate | omitted, it is possible to adjust the duration of an antibacterial and antifungal effect by selecting the composition and quantity of an antibacterial and antifungal agent and a coating material appropriately.

以上のような作用で送風ファン５と空気通路１０７に関してのメンテナンスが不要となる。   Due to the above operation, maintenance of the blower fan 5 and the air passage 107 becomes unnecessary.

最後に、図３によって、本発明全容の説明を行う。   Finally, the whole of the present invention will be described with reference to FIG.

すなわち、図３の（Ａ）は一般従来の空気調和機における各構成要素のメンテナンスのタイミングと空気調和機の耐用年数の関係を示したもので、プレフィルタ４のメンテナンスまでの期間が短いが、このメンテナンスを不要としても、他にも耐用年数より短いメンテナンスまでの期間が短い構成要素が複数存在することが多かった。   That is, (A) of FIG. 3 shows the relationship between the maintenance timing of each component in the general conventional air conditioner and the service life of the air conditioner, and the period until the maintenance of the prefilter 4 is short. Even if this maintenance is not required, there are many other components that have a shorter period until maintenance that is shorter than the service life.

同図の（Ｂ）は、プレフィルタ４を自動清掃化し、他の構成要素のメンテナンス期間も長くした場合であるが、一要素（この場合は脱臭フィルタ）のみがメンテナンス期間が短いために、空気調和機全体としてのメンテナンス期間も、この最も短いメンテナンス期間になってしまう。   (B) in the figure is a case where the pre-filter 4 is automatically cleaned and the maintenance period of other components is extended, but only one element (in this case, the deodorizing filter) has a short maintenance period. The maintenance period of the overall conditioner is also the shortest maintenance period.

本実施例は、この最後の構成要素のメンテナンス期間を破線のように、この空気調和機の耐用年数以上に延ばすことで、空気調和機全体としてのメンテナンス期間も、この空気調和機の耐用年数以上に延ばすことができ、ユーザーはメンテナンスに全く留意することなく、機器が本来持つ機能を低下することなく使用できるようにするものである。   This embodiment extends the maintenance period of this last component to the service life of the air conditioner as indicated by the broken line, so that the maintenance period of the air conditioner as a whole also exceeds the service life of the air conditioner. In this way, the user can use the device without degrading the original function without paying attention to maintenance.

ここで、本明細書内での耐用年数の考え方について説明する。現在の一般的な社会通念上は、空気調和機の耐用年数は約１０年程度と考えられており、メーカーもそのような前提で、機器の寿命設計をしていると考えられる。一方、税法上の冷暖房機器の法定耐用年数は６年とされている。本明細書内で使う耐用年数は、最低限の性能という意味で６年と規定する。   Here, the concept of the service life in this specification will be described. Under the current general social convention, the service life of an air conditioner is considered to be about 10 years, and it is considered that the manufacturer is also designing the lifespan of equipment on such a premise. On the other hand, the legal useful life of air-conditioning equipment under the tax law is 6 years. The service life used in this specification is defined as 6 years in the sense of minimum performance.

（実施の形態２）
図４は、本発明の第二の実施の形態における空気調和機の斜視図と側面図である。 (Embodiment 2)
FIG. 4 is a perspective view and a side view of the air conditioner according to the second embodiment of the present invention.

以下の説明において、実施例１の説明と重複する説明は省略する。   In the following description, descriptions overlapping with those of the first embodiment are omitted.

同図の（Ｂ）は、空気調和機の外観側面形状であるが、（Ｂ）の（ａ）に示す従来一般の空気調和機には、（Ａ）のように開閉パネル１２０を開閉するためのライン１２１が現れるが、（Ｂ）の（ｂ）に示す本実施例では、空気調和機の使用期間内にユーザーはメンテナンスが不要で、開閉パネル１２０を開閉する必要もないため、開閉パネル１２０を前面パネル１２２と一体に形成し、ライン１２１も現れない。   (B) of the figure is the external side shape of the air conditioner, but the conventional general air conditioner shown in (B) (a) opens and closes the open / close panel 120 as shown in (A). However, in this embodiment shown in (B) and (b), the user does not need maintenance during the use period of the air conditioner and does not need to open and close the opening and closing panel 120. Are formed integrally with the front panel 122, and the line 121 does not appear.

このように、本実施例ではユーザーメンテナンスを行うための、部品脱着用の開口部や開閉パネルがない構成としたことで、パネルを開口した際に周囲の家具等と当たるといったことがなくなり、部品数が少なく組み立てやすい簡潔な構成で、なおかつ不要な線や開口が見えないため優れた外観を提供するというものである。   As described above, in this embodiment, since there is no opening part or opening / closing panel for removing parts for performing user maintenance, there is no contact with surrounding furniture or the like when the panel is opened. It has a simple structure that is easy to assemble with few numbers, and provides an excellent appearance because unnecessary lines and openings are not visible.

以上のように、本発明にかかる空気調和機は、吸込口と吹出口とを結ぶ空気通路に、フィルタと、熱交換器と、送風ファンとを夫々設けるとともに、付加機能装置として電気集塵装置、濾過式集塵装置、脱臭手段、イオン発生手段の内の少なくとも１手段を備え、前記フィルタ及び備わる総ての前記付加機能装置が残らず、メンテナンスを行う必要がないように構成してなることで、ユーザーがメンテナンスに全く留意することなく、機器が本来持つ機能を低下することなく使用できるいうものであり、空気調和機の室内機以外に、各種のフィルタ類を有する装置一般に広く適用できる。   As described above, the air conditioner according to the present invention is provided with the filter, the heat exchanger, and the blower fan in the air passage connecting the suction port and the outlet, respectively, and the electric dust collector as an additional function device The filter is equipped with at least one of a dust collector, a deodorizing means, and an ion generating means, so that the filter and all the additional function devices provided are not left and no maintenance is required. Thus, the device can be used without any attention to maintenance and without reducing the functions inherent to the device, and can be widely applied to devices having various filters in addition to the indoor unit of an air conditioner.
