Description

本発明は、塵埃から発生し、起動時（稼働開始時）に排気と共に室内などの外部に放出される不快臭を低減する手段を有した電気掃除機に関するものである。 The present invention relates to a vacuum cleaner having means for reducing an unpleasant odor generated from dust and released to the outside of a room or the like together with exhaust at the time of start-up (operation start).

電気掃除機の集塵部に集塵された塵埃が不快臭の発生源となり、電気掃除機の停止時に機内に不快臭が滞留する。滞留した不快臭は電気掃除機の起動時に排気流と共に電気掃除機の外に放出される。この不快臭の低減のため、従来は排気口部や集塵室の後段といった、吸引風（電気掃除機内部を流れる風）の主流が通気する風路（以下、通風路ということもある）内に脱臭フィルタを搭載する構成が提案されている。 (例えば、特許文献１、２参照)
なお、主流とは、吸引風の主な流れを示すものであり、拡散や渦流により上記吸引風の主な流れから離散していく一部の風の流れを含まないことを意味する。 Dust collected in the dust collection part of the vacuum cleaner becomes a source of unpleasant odor, and unpleasant odor stays in the machine when the vacuum cleaner is stopped. The staying unpleasant odor is discharged out of the vacuum cleaner together with the exhaust flow when the vacuum cleaner is started. In order to reduce this unpleasant odor, the air passage (hereinafter sometimes referred to as a ventilation passage) through which the mainstream of suction air (the air flowing inside the vacuum cleaner) has ventilated, such as the exhaust port and the rear stage of the dust collection chamber, is conventionally used. The structure which mounts a deodorizing filter in is proposed. (For example, see Patent Documents 1 and 2)
The main flow indicates a main flow of the suction air, and means that it does not include a part of the wind flow that is dispersed from the main flow of the suction air due to diffusion or vortex flow.

特開平５-９５８７０号公報（図１、段落０００８、００１０）JP-A-5-95870 (FIG. 1, paragraphs 0008 and 0010) 特許第３２３８０５５号（図１、図２、段落００２２）Japanese Patent No. 3238055 (FIG. 1, FIG. 2, paragraph 0022)

しかしながら、上記のような、通風路に脱臭フィルタを搭載する方法では、吸引風量が大きいため脱臭フィルタと不快臭を含有する排出空気との接触時間が短く脱臭効果が小さい。また、吸引風が脱臭フィルタを通過するため、圧力損失が増加して集塵効率が低下するといった課題があった。 However, in the method in which the deodorizing filter is mounted in the ventilation path as described above, since the suction air volume is large, the contact time between the deodorizing filter and the exhaust air containing unpleasant odor is short and the deodorizing effect is small. Further, since the suction air passes through the deodorizing filter, there is a problem that the pressure loss increases and the dust collection efficiency decreases.

本発明は、係る課題を解決するためになされたもので、塵埃から発する不快臭を高効率で除去でき、かつ圧力損失による集塵効率の低下を最小限に抑えられる臭気除去手段を備えた電気掃除機を提供することを目的とするものである。 The present invention has been made in order to solve the above-mentioned problems, and is an electric device equipped with an odor removing means that can remove an unpleasant odor emitted from dust with high efficiency and can minimize a decrease in dust collection efficiency due to pressure loss. The object is to provide a vacuum cleaner.

本発明に係る電気掃除機は、吸引ホースとの接続口である入口を有する吸引口部と、吸引口部に連通し、塵埃を捕集する集塵部と、集塵部に連通し、塵埃を外気と共に吸引して外部に排出する吸引動力部と、吸引動力部が稼働していない時にも集塵部によって捕集された塵埃から発生する臭気を吸着除去可能な脱臭部と、を備え、吸引口部は、入口と垂直な位置に出口を備え、脱臭部は、水平断面において該脱臭部の一方の面と吸引口部の出口開口面との間に吸引口部の入口を挟むように配置し、かつ吸引口部の入口にかからない位置で吸引口部の出口と対向する位置に設置するものである。 The vacuum cleaner according to the present invention includes a suction port portion having an inlet that is a connection port to a suction hose, a dust collection portion that communicates with the suction port portion, collects dust, and communicates with the dust collection portion. and a by sucking with the outside air suction power section for discharging to the outside, and a suction removable deodorizing unit odor generated from the collected dust by the dust collecting portion even when the suction power section is not running, The suction port portion is provided with an outlet at a position perpendicular to the inlet, and the deodorization portion is arranged so that the inlet of the suction port portion is sandwiched between one surface of the deodorization portion and the outlet opening surface of the suction port portion in a horizontal section. It is arranged and installed at a position facing the outlet of the suction port at a position that does not reach the inlet of the suction port .

本発明によれば、吸引口部、集塵部、ＨＥＰＡフィルタ収納部、吸引動力部で構成される風路の壁面に脱臭部を設けたので、従来と異なり風路を通過する吸引風の主流が脱臭部を直接通過することで発生する圧力損失がなく、集塵効率の低下を抑制でき、なお且つ、電気掃除機の停止時に集塵部内に堆積した塵埃から発生し拡散した不快臭を脱臭部によって除去することで前記掃除機内に不快臭が滞留することを防ぎ、吸引動力の起動時に排出される不快臭を低減することができる。 According to the present invention, since the deodorizing portion is provided on the wall surface of the air passage composed of the suction port portion, the dust collecting portion, the HEPA filter storage portion, and the suction power portion, the mainstream of the suction air passing through the air passage unlike the conventional case. There is no pressure loss caused by directly passing through the deodorizing part, and it is possible to suppress the decrease in dust collection efficiency. By removing by the portion, it is possible to prevent the unpleasant odor from staying in the cleaner, and to reduce the unpleasant odor discharged when the suction power is activated.

実施の形態１．
図１は本発明に係る電気掃除機の実施の形態１を示す上面断面図、図２は前記電気掃除機の側面断面図であり、Ａ−Ａ'断面図である。掃除機本体１は、吸引ホース（図示せず）との接続口である入口と、この入口と水平断面が互いに垂直な開口部を持つ出口とを備えている吸引口部３と、
入口と出口の二つの開口部を同一の面に備え、入口が吸引口部３の出口と連通しており、出口を塞ぐ金属メッシュ５を備えた集塵部４と、
集塵部４の出口と連通した入口と、この入口と水平断面が互いに垂直な開口面を持つ出口とを備え、長手方向の背面が出口を覆う形で設置されているＨＥＰＡフィルタ（High Efficiency Particulate Air Filter）７を収納するＨＥＰＡフィルタ収納部１０と、
モータで駆動されて外気を吸引し、外部空間へ排出する吸引動力部９とで構成される。
なお、ＨＥＰＡフィルタについては、ＪＩＳＺ８１２２によって、「定格風量で粒径が０．３μｍの粒子に対して９９．９７％以上の粒子捕集率をもち、かつ初期圧力損失が２４５Ｐａ以下の性能をもつエアフィルタ」と規定されており、本発明においてもこの規定に従ったものを利用している。実施の形態１については、微小な塵埃が集塵室で捕集しきれず、排気に含まれる悪臭が増加するため、ＨＥＰＡフィルタ７を設置し、残存している塵埃を除去することが望ましい。 Embodiment 1 FIG.
FIG. 1 is a top sectional view showing Embodiment 1 of a vacuum cleaner according to the present invention, FIG. 2 is a side sectional view of the vacuum cleaner, and is an AA ′ sectional view. The vacuum cleaner body 1 includes a suction port 3 having an inlet that is a connection port with a suction hose (not shown), and an outlet having an opening that is perpendicular to the inlet and the horizontal cross section.
Two openings, an inlet and an outlet, are provided on the same surface, the inlet communicates with the outlet of the suction port 3, and a dust collecting unit 4 including a metal mesh 5 that closes the outlet;
An HEPA filter (High Efficiency Particulate) provided with an inlet communicating with the outlet of the dust collecting section 4 and an outlet having an opening surface that is perpendicular to the inlet and the horizontal cross section, and whose rear surface in the longitudinal direction covers the outlet. Air Filter) HEPA filter storage 10 for storing 7;
It comprises a suction power unit 9 that is driven by a motor to suck outside air and discharges it to the external space.
As for the HEPA filter, according to JIS Z 8122, “having a performance of having a particle collection rate of 99.97% or more with respect to particles having a rated air volume of 0.3 μm and an initial pressure loss of 245 Pa or less. The air filter according to this rule is used in the present invention. In the first embodiment, since minute dust cannot be collected in the dust collection chamber and the bad odor contained in the exhaust gas increases, it is desirable to install the HEPA filter 7 and remove the remaining dust.

吸引動力部９の稼働により発生する吸引風の風上側から風下側に向かって吸引口部３、集塵部４、ＨＥＰＡフィルタ収納部１６、吸引動力部９が順次配置され、吸引風流れる通風路を形成している。なお、通風路は、前記通風路以外に分岐路を有していても良く、分岐路は集塵部４を通らずＨＥＰＡフィルタ７に直接繋がっていても良いが、必ず金属メッシュ等の圧損体を有しているものとする。
上記に示される電気掃除機において、脱臭部２は吸引時に通風路内の吸引風の圧力損失が発生しないように吸引風の主流が通気しない位置に設置することが望ましい。例えば、脱臭部２は、図１に示すように、水平断面において吸引口部３の入口の開口面に垂直な位置であり、かつ吸引口３の出口（この出口は吸引口３の入口と垂直な位置関係にある）開口面と対向する位置であり、さらに吸引口３の出口開口面と自分（脱臭部２）の一方の面との間に吸引口３の入口を挟み、かつ吸引口３の入口にかからない位置に、脱着可能な状態で設置されている。また、風路の壁面に凹部を設け、脱臭部２をこの凹部に収納してもよい。この場合、脱臭部２が風路の壁面から張り出していると、張り出した部分が排気流の主流に当たるので、排気流の圧力損失が発生して吸引性能の劣化を招く。また、凹部に収納されている脱臭部２の一方の面が風路の壁面よりも凹んでいると、凹んでいる部分に塵埃が堆積し、脱臭部２の性能劣化を招く。従って、このような問題を解消するために、脱臭部２の一方の面を風路壁面の高さに合うように脱臭部２を凹部に取り付けるのが好ましい。
なお、上記の条件を満たすような位置であれば、図１および図２に限らず、図３および図４（図３のＢ−Ｂ'断面図）に示すように脱臭部２を吸引口部３の風路上部の凹部に収納しても良いし、図５および図６（図５のＣ−Ｃ'断面図）に示すように脱臭部２を集塵部４の風路上部の凹部に収納しても良いし、図７および図８（図７のＤ−Ｄ'断面図）に示すように吸引口部３の入口（吸引ホース接続口近傍）の上面、側面、下面のいずれの凹部に収納しても良い。
図９は本発明に係る電気掃除機で用いられる脱臭部２の構成を示す図である。図９に示すように脱臭部２はケース１０に収納された状態で固定される。この脱臭部１２が収納されたケース１０を通風路の壁面または凹部にセットしてネジまたはケースと一体で成形された爪具により固定することで、脱臭部１２を着脱自在に設置することができる。なお、脱臭部２はコルゲート状、ハニカム状、四角状または繊維状等の広い表面積を有する形状であることが望ましく、ゼオライト、活性炭、シリカゲル等のメソ孔（直径２〜５０ｎｍの小孔）あるいはミクロ孔（直径０．２〜０．５ｎｍの小孔）を有する多孔質吸着剤、酸化マンガン、酸化チタン等の遷移金属を中心とした細孔構造を有する多孔質金属酸化物、および白金、パラジウム等の貴金属のうち１種類以上が担持されたペーパーセラミックもしくはコージェライト等からなるのが望ましい。ケース１０は吸引口部３の底部に容易に脱着可能となるよう、爪、ネジ等で固定され、脱臭部２を固定する役割を果たす。金属メッシュ５は集塵部４の出口開口面を覆うように取り付けられている。 The suction port 3, the dust collecting unit 4, the HEPA filter storage unit 16, and the suction power unit 9 are sequentially arranged from the upstream side of the suction air generated by the operation of the suction power unit 9 toward the leeward side, and the ventilation path through which the suction air flows. Is forming. The ventilation path may have a branching path other than the ventilation path, and the branching path may be directly connected to the HEPA filter 7 without passing through the dust collecting portion 4, but is always a pressure loss body such as a metal mesh. It shall have.
In the vacuum cleaner shown above, it is desirable that the deodorizing unit 2 is installed at a position where the main flow of the suction air does not flow so that the pressure loss of the suction air in the ventilation path does not occur during suction. For example, as shown in FIG. 1, the deodorizing unit 2 is in a position perpendicular to the opening surface of the inlet of the suction port 3 in a horizontal section, and the outlet of the suction port 3 (this outlet is perpendicular to the inlet of the suction port 3). The inlet of the suction port 3 is sandwiched between the outlet opening surface of the suction port 3 and one surface of itself (deodorizing part 2), and the suction port 3 It is installed in a detachable position at a position that does not reach the entrance. Moreover, a recessed part may be provided in the wall surface of an air path, and the deodorizing part 2 may be accommodated in this recessed part. In this case, if the deodorizing part 2 projects from the wall surface of the air passage, the projecting part hits the main flow of the exhaust flow, so that a pressure loss of the exhaust flow occurs and the suction performance deteriorates. Moreover, when one surface of the deodorizing part 2 accommodated in the recessed part is recessed from the wall surface of an air path, dust will accumulate on the recessed part and the performance of the deodorizing part 2 will be caused. Therefore, in order to eliminate such a problem, it is preferable to attach the deodorizing part 2 to a recessed part so that one surface of the deodorizing part 2 may match the height of an air channel wall surface.
In addition, if it is a position which satisfy | fills said conditions, as shown in FIG. 3 and FIG. 4 (BB 'sectional drawing of FIG. 3) not only FIG. 1 and FIG. 3 may be housed in a recess in the upper part of the air passage, or the deodorizing part 2 may be placed in a recess in the upper part of the air path of the dust collecting part 4 as shown in FIGS. As shown in FIG. 7 and FIG. 8 (DD ′ cross-sectional view of FIG. 7), any recess on the upper surface, side surface, or lower surface of the inlet (near the suction hose connection port) of the suction port 3 It may be stored in.
FIG. 9 is a diagram showing a configuration of the deodorizing unit 2 used in the electric vacuum cleaner according to the present invention. As shown in FIG. 9, the deodorizing unit 2 is fixed in a state of being housed in the case 10. The deodorizing part 12 can be detachably installed by setting the case 10 containing the deodorizing part 12 in the wall surface or recess of the air passage and fixing with a screw or a nail formed integrally with the case. . The deodorizing part 2 preferably has a corrugated shape, a honeycomb shape, a square shape, a fiber shape or the like having a large surface area, such as mesopores (small pores having a diameter of 2 to 50 nm) such as zeolite, activated carbon, silica gel, etc. Porous adsorbent having pores (small pores having a diameter of 0.2 to 0.5 nm), porous metal oxide having a pore structure centered on transition metals such as manganese oxide and titanium oxide, and platinum, palladium, etc. It is desirable to be made of paper ceramic or cordierite on which one or more kinds of noble metals are supported. The case 10 is fixed with a nail, a screw or the like so that it can be easily attached to and detached from the bottom of the suction port portion 3, and plays a role of fixing the deodorizing portion 2. The metal mesh 5 is attached so as to cover the outlet opening surface of the dust collecting portion 4.

次に、実施の形態１の動作について説明する。
上記図１に示す構成の電気掃除機では、吸引動力部９の起動時に、図示しない吸引ホースからの吸引風が吸引口部３、集塵部４、ＨＥＰＡフィルタ７を順次流通し、吸引風に含まれる粗大な塵埃が金属メッシュ５に捕集され、集塵部４に蓄積される。金属メッシュ５で捕集されなかった微小な塵埃はＨＥＰＡフィルタ７によって捕集され、吸引動力部９には達しない。このとき集塵部４に蓄積された粗大な塵埃には食べ物のカスや毛髪やフケさらにはこれらに付着するダニやその死骸などが含まれており、吸引動力部９が稼動してない状態の時に、酸化や微生物による分解が進み不快臭を発生する。特に温度および湿度の高い夏や梅雨の季節には不快臭の発生は著しくなる。仮に脱臭部２がないと、発生した不快臭により、集塵部４とそれ以外の場所には不快臭の濃度勾配が生み出され、濃度平衡となるよう掃除機本体１の中を滞留する。このとき不快臭は、圧損体として働いている金属メッシュ５やＨＥＰＡフィルタ７に拡散を妨げられるため、拡散の妨げがない風上側に位置する、吸引口部３へと向かって拡散する。このように滞留した不快臭は吸引動力部９を再稼動させた際に、排気臭となり掃除機の外部に放出され、使用者に不快感を与える原因となる。 Next, the operation of the first embodiment will be described.
In the vacuum cleaner having the configuration shown in FIG. 1, when the suction power unit 9 is started, suction air from a suction hose (not shown) sequentially flows through the suction port portion 3, the dust collection portion 4, and the HEPA filter 7 to generate suction air. Coarse dust contained therein is collected by the metal mesh 5 and accumulated in the dust collecting unit 4. The minute dust not collected by the metal mesh 5 is collected by the HEPA filter 7 and does not reach the suction power unit 9. At this time, the coarse dust accumulated in the dust collecting unit 4 includes food residue, hair, dandruff, mites adhering to these, and dead bodies thereof, and the suction power unit 9 is not in operation. Occasionally, oxidation and decomposition by microorganisms progress and generate unpleasant odors. The generation of unpleasant odors is particularly noticeable in summer and rainy season when the temperature and humidity are high. If the deodorizing unit 2 is not present, the unpleasant odor generated causes a concentration gradient of the unpleasant odor in the dust collecting unit 4 and other locations, and the deodorizing unit 2 stays in the cleaner body 1 so as to achieve concentration equilibrium. At this time, the unpleasant odor is prevented from diffusing by the metal mesh 5 or the HEPA filter 7 acting as a pressure loss body, and thus diffuses toward the suction port 3 located on the windward side where the diffusion is not hindered. The unpleasant odor that stays in this way becomes an exhaust odor when the suction power unit 9 is restarted, and is released to the outside of the vacuum cleaner, causing discomfort to the user.

そこで、本実施の形態１における電気掃除機では、集塵部４と連通する吸引口部３内（図１および図２）、集塵部４と吸引口部３の間（図３および図４）、集塵部４内（図５および図６）などに脱臭部２を設置することで、吸引動力部９が稼動していない時に、吸引口部３へ拡散した塵埃からの不快臭を吸着除去する。この脱臭作用により、不快臭の掃除機本体１への滞留を防止でき、結果的に吸引動力部９を再稼動させた際の排気臭が低減され、使用者の不快感を低減できる。また、吸引口部３内の出口と対向する位置に脱臭部２を設置することで、脱臭部２が吸引風中の塵埃に覆われることなく、また、通風路内の吸引風の流れの主流が脱臭部２を通気しないことにより吸引時の圧力損失を低減できるため、脱臭部２の設置により吸引動力部９の負荷増加による集塵効率低下を招くことなく脱臭効果を得ることができる。 Therefore, in the vacuum cleaner of the first embodiment, the inside of the suction port portion 3 (FIGS. 1 and 2) communicating with the dust collection portion 4 and between the dust collection portion 4 and the suction port portion 3 (FIGS. 3 and 4). ) By installing the deodorizing unit 2 in the dust collecting unit 4 (FIGS. 5 and 6), the unpleasant odor from the dust diffused to the suction port 3 is adsorbed when the suction power unit 9 is not operating. Remove. Due to this deodorizing action, unpleasant odor can be prevented from staying in the vacuum cleaner main body 1, and as a result, the exhaust odor when the suction power unit 9 is restarted is reduced, thereby reducing the user's unpleasant feeling. In addition, by installing the deodorizing unit 2 at a position facing the outlet in the suction port 3, the deodorizing unit 2 is not covered with dust in the suction air, and the main flow of the suction air in the ventilation path However, since the pressure loss at the time of suction can be reduced by not ventilating the deodorizing unit 2, the deodorizing effect can be obtained without degrading the dust collection efficiency due to the increased load of the suction power unit 9 by installing the deodorizing unit 2.

脱臭部２には、家庭用一般ゴミから排出される不快臭の主な成分として挙げられる、アンモニア、アセトアルデヒド、イソ吉草酸、二硫化メチルの吸着力、吸着総容量に優れる素材を用いる必要がある。従って、これらの成分に対し、吸着力、吸着総容量共に優れている、コルゲート状、ハニカム状、四角状または繊維状等を有する表面積が広いフィルタに、ゼオライト、活性炭、シリカゲル等のメソ孔あるいはミクロ孔を有する比表面積が大きい多孔質吸着剤を担持した物を脱臭部２に用いるのが適している。さらに、触媒作用を持たせ、触媒上での臭気成分の分解を促進させるために、酸化マンガン、酸化チタン等の遷移金属を中心とした細孔構造を有する多孔質金属酸化物、および白金、パラジウム等の貴金属が１種類以上担持されている物を用いるのが望ましい。 In the deodorizing part 2, it is necessary to use a material excellent in adsorption power and adsorption total capacity of ammonia, acetaldehyde, isovaleric acid and methyl disulfide, which are listed as main components of unpleasant odor discharged from household general waste. . Therefore, for these components, a filter having a large surface area, such as corrugated, honeycomb, square or fiber, which has excellent adsorption power and total adsorption capacity, is applied to mesopores such as zeolite, activated carbon, silica gel, etc. It is suitable to use for the deodorization part 2 the thing which carry | supported the porous adsorbent with a large specific surface area which has a hole. Furthermore, in order to provide catalytic action and promote the decomposition of odor components on the catalyst, porous metal oxides having a pore structure centered on transition metals such as manganese oxide and titanium oxide, and platinum and palladium It is desirable to use a material in which one or more kinds of noble metals are supported.

次に、本実施の形態１における電気掃除機の脱臭部２の違いによる脱臭性能の差を示す。
図１０は脱臭部２を設置しない状態で電気掃除機の内部に不快臭発生源を吸引させた際の集塵部４、吸引口部３、ＨＥＰＡ前部６およびＨＥＰＡ後部８でのアセトアルデヒド濃度の時間変化を示す図である。ここで示す不快臭発生源はアセトアルデヒド溶液を吸収させた繊維状ペーパーである。妨げが無く連通している集塵部４および吸引口部３は濃度の経時変化は等しく、最初にアセトアルデヒドが放出され、急激に拡散するため一時的な濃度増加が起こり、急激に減少するが、放出が一定となり、拡散しきると濃度が安定する傾向が確認できる。しかし、金属メッシュ５に妨げられているＨＥＰＡ前部６は、集塵部４および吸引口部３に対し初期の濃度増加が半減し、安定後の濃度も低い。更にＨＥＰＡフィルタ７にも遮られているＨＥＰＡ後部８では殆ど濃度変動が確認できず、低濃度で安定している傾向が見られる。このことから、金属メッシュ５やＨＥＰＡフィルタ７といった圧損体として働く遮蔽物は不快臭の拡散を妨げ、脱臭に影響を及ぼすことが分かる。 Next, the difference of the deodorizing performance by the difference of the deodorizing part 2 of the vacuum cleaner in this Embodiment 1 is shown.
FIG. 10 shows the concentration of acetaldehyde in the dust collecting part 4, the suction port part 3, the HEPA front part 6 and the HEPA rear part 8 when an unpleasant odor source is sucked into the vacuum cleaner without the deodorizing part 2 installed. It is a figure which shows a time change. The unpleasant odor source shown here is fibrous paper that has absorbed an acetaldehyde solution. The dust collection part 4 and the suction port part 3 communicated with each other without any obstruction have the same change in concentration over time. First, acetaldehyde is released and diffuses rapidly, causing a temporary increase in concentration, which decreases rapidly. Emission is constant, and the concentration can be confirmed to be stable when diffused. However, the HEPA front part 6 hindered by the metal mesh 5 is halved in the initial density increase relative to the dust collection part 4 and the suction port part 3, and the density after stabilization is also low. Further, almost no density fluctuation can be confirmed in the HEPA rear part 8 which is also blocked by the HEPA filter 7, and there is a tendency that the density is stable at a low density. From this, it can be seen that the shields acting as pressure loss bodies such as the metal mesh 5 and the HEPA filter 7 prevent diffusion of unpleasant odors and affect deodorization.

図１１は集塵部４、吸引口部３、ＨＥＰＡフィルタ収納部１０のＨＥＰＡ前部６およびＨＥＰＡ後部８にそれぞれ脱臭部２を設置し、集塵部４に不快臭発生源を吸引させた際に、蔓延し、外部に流出した不快臭の濃度経時変化を示す。ここで示す不快臭発生源は図１０と同様、アセトアルデヒド溶液を吸収させた繊維状のペーパーである。なお、図１１において、ブランクは脱臭部２が設置されていない場合の電気掃除機からの不快臭放出量の時間変化を示している。図１０の結果に示される、不快臭拡散が最も顕著に起こる集塵部４および吸引口部３に脱臭部２を設置した場合、脱臭部２への不快臭の吸着が十分に行われるため、アセトアルデヒドの掃除機外部への放出は抑制される傾向を示すが、ＨＥＰＡ前部６およびＨＥＰＡ後部８では不快臭の拡散が妨げられるため、脱臭部２へ不快臭が到達しきらず、十分な脱臭性能を得ることが出来ない。
図１２は触媒設置位置の違いにおける、吸引動力部９の回転数に対する吸引風量の変化を示す図である。通風路内の吸引風の主流が通気しない集塵部４の入口に対向する位置に脱臭部２を設置した際の回転数に対する風量増加に対し、通風路内の吸引風の主流が通気する位置に脱臭部２を設置した際の風量増加が抑制されている傾向が確認できる。特に風量増加に伴い触媒設置位置の違いによる影響は大きく現れる。吸引風量の低下は集塵効率の低下に直結するため、通風路内の吸引風の主流が通気する位置を避け、触媒を設置することが有効であることがわかる。
図１３は脱臭部２の比表面積の増加に伴う脱臭部材１ｇのイソ吉草酸の吸着量の変化を示す図である。イソ吉草酸挿入量２８ｍｇに対し、比表面積の増加に伴う吸着量の増加が確認でき、比表面積９００ｍ２／ｇ以上でほぼ全てを吸着する性能に達する。よって、十分な吸着性能を得るには広い比表面積を有する吸着材料を使用する必要がある。特に多孔質であり、メソ孔やミクロ孔を有する、ゼオライト、活性炭、シリカゲル等を用いるのが望ましい。 FIG. 11 shows a case where the deodorizing unit 2 is installed in the dust collecting unit 4, the suction port unit 3, the HEPA front unit 6 and the HEPA rear unit 8 of the HEPA filter storage unit 10, respectively, and the dust collecting unit 4 sucks an unpleasant odor source. Fig. 5 shows the change over time in the concentration of unpleasant odor that spreads and flows out to the outside. The unpleasant odor source shown here is a fibrous paper in which an acetaldehyde solution is absorbed, as in FIG. In addition, in FIG. 11, the blank has shown the time change of the amount of unpleasant odor discharge | release from a vacuum cleaner in case the deodorizing part 2 is not installed. When the deodorizing part 2 is installed in the dust collecting part 4 and the suction port part 3 where the unpleasant odor diffusion occurs most noticeably as shown in the result of FIG. 10, the adsorption of the unpleasant odor to the deodorizing part 2 is sufficiently performed. Although the release of acetaldehyde to the outside of the vacuum cleaner tends to be suppressed, diffusion of unpleasant odor is hindered in the HEPA front part 6 and the HEPA rear part 8, so that the unpleasant odor does not reach the deodorizing part 2 and sufficient deodorizing performance. Can not get.
FIG. 12 is a diagram showing a change in the suction air volume with respect to the rotation speed of the suction power unit 9 in the difference in the catalyst installation position. The position where the main flow of the suction air in the ventilation passage vents against the increase in the air volume with respect to the rotation speed when the deodorizing unit 2 is installed at the position facing the inlet of the dust collecting portion 4 where the main flow of the suction air in the ventilation passage does not vent The tendency which the increase in the air volume at the time of installing the deodorizing part 2 is suppressed can be confirmed. In particular, as the air volume increases, the effect of the difference in the catalyst installation position appears greatly. It can be seen that the reduction in the suction air amount directly leads to the reduction in the dust collection efficiency, so that it is effective to install the catalyst while avoiding the position where the main flow of the suction air in the ventilation path is vented.
FIG. 13 is a diagram showing a change in the amount of isovaleric acid adsorbed by 1 g of the deodorizing member as the specific surface area of the deodorizing unit 2 increases. With respect to the insertion amount of isovaleric acid of 28 mg, an increase in the adsorption amount accompanying an increase in the specific surface area can be confirmed, and the performance of adsorbing almost all at a specific surface area of 900 m2 / g or more is reached. Therefore, in order to obtain sufficient adsorption performance, it is necessary to use an adsorbent material having a wide specific surface area. In particular, it is desirable to use zeolite, activated carbon, silica gel or the like which is porous and has mesopores or micropores.

以上のように、上記に示す電気掃除機は、吸引動力部９と、微小粒子の吸引動力部９への流入を防ぐために設けられたＨＥＰＡフィルタ７と、吸引した塵埃の吸引動力部方向への流出を防ぐために吸引風排出方向に設けられた金属メッシュ５を内部に備えている集塵部４と、脱臭部２を出口と対向する位置に有する吸引口部３とで構成されており、吸引口部３、集塵部４、ＨＥＰＡフィルタ７、吸引動力部９の順に配置され、この吸引口部３、集塵部４、ＨＥＰＡフィルタ７、吸引動力部９で通風路が形成されており、脱臭部２は通風路内の風の流れの主流が通気せず、吸引時の圧力損失を及ぼさない吸引口部３の入口から流入する吸引風の主流の左側で、出口に対向する位置に設置されており、コルゲート状、ハニカム状、四角上または繊維状等の表面積が広いフィルタであり、ゼオライト、活性炭、シリカゲル等のメソ孔あるいはミクロ孔を有する多孔質吸着剤、酸化マンガン酸化チタン等の遷移金属を中心とした細孔構造を有する多孔質金属酸化物、および白金、パラジウム等の貴金属がそれぞれ１種類以上担持されていることにより、吸引動力部９が稼動してない状態の時に吸引口部３へ拡散した塵埃からの不快臭を吸着除去し、不快臭の掃除機本体１への充満を防止でき、結果的に吸引動力部９を再稼動させた際の排気臭が低減され、使用者の不快感を取り除け、通風路内の風の流れの主流が通気せず、吸引時の圧力損失を低減でき、脱臭部２の設置が吸引動力部９に対する負荷増加による集塵効率低下を伴うことなく脱臭効果を得られる。 As described above, the vacuum cleaner shown above has the suction power unit 9, the HEPA filter 7 provided to prevent the inflow of fine particles into the suction power unit 9, and the suction dust toward the suction power unit. In order to prevent the outflow, it is composed of a dust collecting part 4 provided inside with a metal mesh 5 provided in the suction air discharge direction, and a suction port part 3 having a deodorizing part 2 at a position opposite to the outlet. The mouth portion 3, the dust collection portion 4, the HEPA filter 7, and the suction power portion 9 are arranged in this order, and the suction port portion 3, the dust collection portion 4, the HEPA filter 7, and the suction power portion 9 form a ventilation path. The deodorizing unit 2 is installed at a position facing the outlet on the left side of the main flow of the suction air flowing from the inlet of the suction port 3 that does not allow the main flow of the wind flow in the ventilation path to vent and does not cause pressure loss during suction. Corrugated, honeycomb, square or fine Porous metal oxide with a porous structure centering on transition metals such as porous adsorbents such as zeolite, activated carbon, silica gel and other mesopores or micropores, manganese oxide titanium oxide, etc. And one or more kinds of precious metals such as platinum and palladium are carried to adsorb and remove unpleasant odors from dust diffused to the suction port 3 when the suction power unit 9 is not in operation, The unpleasant odor can be prevented from filling the vacuum cleaner main body 1 and, as a result, the exhaust odor when the suction power unit 9 is restarted is reduced. The mainstream is not vented, the pressure loss during suction can be reduced, and the installation of the deodorizing unit 2 can provide a deodorizing effect without lowering the dust collection efficiency due to an increased load on the suction power unit 9.

以上より、本実施の形態１によれば、吸引口部と集塵部の間を通る通風路内の、気流に与える影響が軽微である吸引風の主流が直接通気しない位置に脱臭部を設けたので、電気掃除機の停止時に集塵部内の塵埃から発生し拡散した不快臭を除去することで前記掃除機内の不快臭の滞留を防ぐことができ、集塵効率を低下させることなく吸引動力の起動時に排出される不快臭を低減することができるという効果を奏する。 As described above, according to the first embodiment, the deodorizing part is provided in the ventilation path passing between the suction port part and the dust collecting part at a position where the main stream of the suction air that has a slight effect on the air current is not directly ventilated. Therefore, by removing the unpleasant odor generated and diffused from the dust in the dust collector when the vacuum cleaner is stopped, it is possible to prevent the unpleasant odor from staying in the vacuum cleaner, and the suction power without reducing the dust collection efficiency The effect that the unpleasant odor discharged | emitted at the time of starting of can be reduced is produced.

実施の形態２．
図１４は本発明に係る電気掃除機の実施の形態２を示す上断面図であり、実施の形態１記載の電気掃除機の集塵部４に集塵袋１１を取り付けた場合を示している。集塵部４に集塵袋１１を取り付けた場合、集塵袋１１そのものが圧損体となり、吸引動力部９への塵埃の流入が防がれる。脱臭部２は集塵袋１１の入口と連通し、通風路内の主流が通気せず、吸引時の圧力損失が及ばないように、通風路側面に埋め込み設置される。このように構成することにより、実施の形態１記載の電気掃除機同様、集塵効率を低下させることなく吸引動力の起動時に排出される不快臭を低減する事が可能となる。
この時、集塵袋１１は脱着可能であり、ゼオライト、シリカゲル、活性炭等の吸着剤、化学添着剤、酸化マンガン、酸化チタン等の金属酸化物、白金、パラジウム等の貴金属のいずれかまたは両方を添着し、用いることで、集塵袋１１内に集塵された塵埃に含まれる不快臭の放出を低減され、脱臭部２の延命を図ることができる。 Embodiment 2. FIG.
FIG. 14 is a top sectional view showing a second embodiment of the electric vacuum cleaner according to the present invention, and shows a case where the dust collecting bag 11 is attached to the dust collecting portion 4 of the electric vacuum cleaner described in the first embodiment. . When the dust collection bag 11 is attached to the dust collection unit 4, the dust collection bag 11 itself becomes a pressure loss body, and the inflow of dust to the suction power unit 9 is prevented. The deodorizing unit 2 communicates with the inlet of the dust bag 11 and is embedded and installed on the side surface of the ventilation path so that the main flow in the ventilation path is not vented and pressure loss at the time of suction does not reach. By comprising in this way, it becomes possible to reduce the unpleasant odor discharged | emitted at the time of starting of suction power, without reducing dust collection efficiency similarly to the vacuum cleaner of Embodiment 1. FIG.
At this time, the dust bag 11 is detachable, and adsorbent such as zeolite, silica gel and activated carbon, chemical additive, metal oxide such as manganese oxide and titanium oxide, or noble metal such as platinum and palladium, or both. By attaching and using, emission of unpleasant odor contained in the dust collected in the dust bag 11 can be reduced, and the life of the deodorizing unit 2 can be extended.

上記構成の電気掃除機の動作について説明する。
上記構成の掃除機では、吸引動力部９を稼動させると、吸引風が吸引部３、集塵部４ＨＥＰＡフィルタ７を順次流通し、吸引風に含まれる粗大な塵埃が集塵袋１１に遮られ、集塵部４に蓄積される構造となっている。集塵袋１１は一般家庭内の２〜６週間分の塵埃を蓄積できる容積を有する。脱臭部２は集塵袋１１に蓄積される塵埃から放出される不快臭を吸着する。しかし、同時に集塵袋１１に対しても不快臭の付着が起こり、十分量の塵埃が集塵袋１１に蓄積された際、集塵袋１１そのものが不快臭を発するため、集塵袋１１そのものにも脱臭機能を付与するのが望ましい。例えば、多種多様な成分に効果が認められ、多孔質で比表面積が広く臭気吸着総容量に優れている、ペーパー化加工が可能な活性炭に、活性炭のみでは吸着が難しいアンモニアやアセトアルデヒドに対応した化学添着剤を塗りこんだものが効果的である。
図１５は、紙および活性炭に対する、二硫化メチル（二硫化メチルは腐ったキャベツの臭いがする）の総吸着量を示す。紙では全く吸着効果が見られないのに対し、活性炭では２週間分の塵埃から放出される二硫化メチルを殆ど吸着することが可能な吸着総容量を有することがこの結果から分かる。
図１６は活性炭および紙の化学添着剤有無に対するアンモニア総吸着量の違いを示す図である。図１６に示すように、活性炭のみでは自然に減衰する量と変わらず、殆ど吸着が起こらないことがわかる。また、紙のみである程度のアンモニア吸着が認められるが、２週間分の塵埃からの発生量を吸着しきるほどの性能は得られない。これに対し、化学添着剤を塗りこむことで、活性炭、紙のいずれも、２週間分の塵埃から発生するアンモニアガスを吸着する性能を得ることが可能となる。 Operation | movement of the vacuum cleaner of the said structure is demonstrated.
In the vacuum cleaner having the above-described configuration, when the suction power unit 9 is operated, the suction air sequentially flows through the suction unit 3 and the dust collection unit 4 HEPA filter 7, and coarse dust contained in the suction air is blocked by the dust collection bag 11. The structure is accumulated in the dust collecting unit 4. The dust bag 11 has a volume capable of storing dust for 2 to 6 weeks in a general household. The deodorizing unit 2 absorbs an unpleasant odor emitted from the dust accumulated in the dust bag 11. However, at the same time, an unpleasant odor is attached to the dust collection bag 11, and when a sufficient amount of dust is accumulated in the dust collection bag 11, the dust collection bag 11 itself generates an unpleasant odor. It is desirable to provide a deodorizing function. For example, it is effective for a wide variety of components, it is porous, has a large specific surface area and excellent total odor adsorption capacity. It can be activated by paper, and it can handle ammonia and acetaldehyde, which are difficult to adsorb only by activated carbon. A coating with an additive is effective.
FIG. 15 shows the total amount of methyl disulfide (methyl disulfide smells of rotten cabbage) on paper and activated carbon. It can be seen from this result that the paper has no adsorption effect, whereas the activated carbon has a total adsorption capacity capable of almost adsorbing methyl disulfide released from dust for two weeks.
FIG. 16 is a diagram showing the difference in the total ammonia adsorption amount with respect to the presence or absence of a chemical additive for activated carbon and paper. As shown in FIG. 16, it can be seen that only the activated carbon does not change the amount of natural decay and hardly adsorbs. Moreover, although ammonia adsorption to some extent is recognized only with paper, the performance which can adsorb | suck the generation amount from dust for two weeks is not acquired. On the other hand, by applying a chemical additive, both activated carbon and paper can obtain the performance of adsorbing ammonia gas generated from dust for two weeks.

以上より、本実施の形態２によれば、集塵部に脱着可能な集塵袋を備えたので、不快臭の放出を低減され、脱臭部の延命を図ることができる。また、脱臭部は集塵袋の入口と連通し、通風路内の主流が通気せず、吸引時の圧力損失が及ばないように、通風路側面に埋め込み設置されるので、集塵効率を低下させることなく吸引動力の起動時に排出される不快臭を低減することが可能となるという効果を奏する。 As described above, according to the second embodiment, since the detachable dust collection bag is provided in the dust collection section, the emission of unpleasant odor can be reduced and the life of the deodorization section can be extended. In addition, the deodorization part communicates with the entrance of the dust bag, and the main flow in the ventilation path is not vented, so it is embedded in the side of the ventilation path so that the pressure loss during suction does not reach, reducing the dust collection efficiency. There is an effect that it is possible to reduce the unpleasant odor that is discharged when the suction power is activated without causing it.

実施の形態３．
実施の形態１及び２では、通風路はホースからの排気流を利用したものであった。しかしながら、これに限るものではなく、掃除機本体に開口部を設け、そこから通風しても良い。本実施の形態３では、このような実施の形態について説明する。図１７は本発明に係る電気掃除機の実施の形態３を示す上面断面図、図１８は本発明に係る電気掃除機の実施の形態３を示す側面断面図である。図１９は本発明の実施の形態３における、脱臭部２と開口部で構成される通風路を示す斜視図である。 Embodiment 3 FIG.
In the first and second embodiments, the ventilation path uses the exhaust flow from the hose. However, it is not restricted to this, You may provide an opening part in a cleaner main body, and may ventilate from there. In the third embodiment, such an embodiment will be described. FIG. 17 is a top sectional view showing Embodiment 3 of the electric vacuum cleaner according to the present invention, and FIG. 18 is a side sectional view showing Embodiment 3 of the electric vacuum cleaner according to the present invention. FIG. 19 is a perspective view showing a ventilation path composed of deodorizing section 2 and an opening according to Embodiment 3 of the present invention.

図１７〜図１９に示すように、本実施の形態３では、実施の形態１に記載の電気掃除機の吸引口部３から脱臭部２の集塵部側と反対側の方向に通風路を設けている。この通風路に沿って吸引口部３から外部の方向に脱臭部２、放電電極１５、ファン１２、開口部１３を順次配置する。脱臭部２の通風路が設置されている面の裏側は吸引口部３に連通しており、ファン１２が回転することで、開口部１３から空気を吸引し、放電電極１５、脱臭部２を通り、吸引口部３に対し、風を流入させることが可能となる。開口部１３には圧損体、弁などの開閉機能のいずれかまたは両方を有することが望ましい。
次に動作について説明する。 As shown in FIGS. 17-19, in this Embodiment 3, a ventilation path is provided in the direction on the opposite side to the dust collection part side of the deodorizing part 2 from the suction opening part 3 of the vacuum cleaner as described in Embodiment 1. FIG. Provided. The deodorizing part 2, the discharge electrode 15, the fan 12, and the opening part 13 are sequentially arranged from the suction port part 3 toward the outside along the ventilation path. The back side of the surface where the ventilation path of the deodorizing part 2 is installed communicates with the suction port part 3, and the fan 12 rotates to suck air from the opening part 13, so that the discharge electrode 15 and the deodorizing part 2 are connected. As a result, it is possible to allow wind to flow into the suction port portion 3. It is desirable that the opening 13 has either or both of an opening / closing function such as a pressure loss body and a valve.
Next, the operation will be described.

上記構成の電気掃除機に示されるように脱臭部２が通風可能な形状となっており、脱臭部２の集塵部４と反対の方向に、前記通風路を妨げない形で、放電電極１５、ファン１２および開口部１３を順次配置した別の通風路１７を備える。そして、吸引動力部９が停止している際にファン１２を回転することで脱臭部２に対し送風を行い、吸引動力部９の稼動時に脱臭部２の集塵部４側の面に堆積した、脱臭部２への拡散臭気の吸着作用の妨げとなる塵埃を集塵部４に向かって吹き飛ばせる。また、送風と同時に放電電極１５から脱臭部２に対し放電を行うことで、脱臭部２に吸着された臭気成分を分解し洗浄することが可能となる。これらの作用により、脱臭部２の脱臭性能の長寿命化を図ることが可能となる。さらに、開口部１２に圧損体、開閉機能のいずれかまたは両方を有することで、吸引動力部９稼動時の開口部からの吸引を妨げることができ、吸引風量の低下を抑制することが可能となる。
図２０は脱臭部２の表面に対する塵埃の堆積による脱臭性能劣化度合を示す図である。図２０に示すように、脱臭部２の塵埃の堆積量増加に伴う不快臭除去性能の劣化が起こる。従って、ファン１２を回転することで脱臭部２の集塵部４と対向する２つの面の内、ファン側へ向いている面から、集塵部４側へ向く面に対し送風を行い、脱臭部２の表面に堆積していた塵埃を集塵部４に向かって吹き飛ばす。これにより、脱臭部２への塵埃の堆積による劣化を防ぐことが可能となる。
図２１は十分量のアセトアルデヒドを吸着して飽和したゼオライトと酸化マンガンを担持した触媒フィルタに対し、コロナ放電により放電を行った時の触媒フィルタからの二酸化炭素発生量を示す図である。アセトアルデヒドは、コロナ放電を印加することで酸素ラジカルにより酸化され、二酸化炭素に分解される。従って、フィルタからの二酸化炭素の放出量が増加するということは、フィルタ上に吸着されたアセトアルデヒドが分解され、フィルタ表面が清浄化されていることを意味しており、脱臭部２に対し、コロナ放電等を有する放電電極１５により放電を行うことで、脱臭部２の寿命を大幅に延ばすことができる。 As shown in the vacuum cleaner having the above-described configuration, the deodorizing part 2 has a shape allowing ventilation, and the discharge electrode 15 is formed in the direction opposite to the dust collecting part 4 of the deodorizing part 2 so as not to obstruct the ventilation path. In addition, another ventilation path 17 in which the fan 12 and the opening 13 are sequentially arranged is provided. Then, when the suction power unit 9 is stopped, the fan 12 is rotated to blow air to the deodorizing unit 2 and accumulated on the surface of the deodorizing unit 2 on the dust collecting unit 4 side when the suction power unit 9 is operated. The dust that hinders the action of adsorbing the diffuse odor to the deodorizing unit 2 is blown off toward the dust collecting unit 4. Moreover, it becomes possible to decompose | disassemble and wash | clean the odor component adsorbed by the deodorizing part 2 by discharging with respect to the deodorizing part 2 from the discharge electrode 15 simultaneously with ventilation. By these actions, it is possible to extend the life of the deodorizing performance of the deodorizing unit 2. Furthermore, by having either or both of the pressure loss body and the opening / closing function in the opening 12, it is possible to prevent suction from the opening during operation of the suction power unit 9, and to suppress a decrease in the suction air volume. Become.
FIG. 20 is a diagram showing the degree of deodorization performance deterioration due to dust accumulation on the surface of the deodorizing unit 2. As shown in FIG. 20, the unpleasant odor removal performance deteriorates as the amount of dust accumulated in the deodorizing unit 2 increases. Therefore, by rotating the fan 12, air is blown from the surface facing the dust collecting unit 4 of the deodorizing unit 2 to the surface facing the dust collecting unit 4 from the surface facing the fan side. The dust accumulated on the surface of the part 2 is blown off toward the dust collecting part 4. As a result, it is possible to prevent deterioration due to dust accumulation on the deodorizing unit 2.
FIG. 21 is a graph showing the amount of carbon dioxide generated from a catalyst filter when a catalyst filter carrying zeolite and manganese oxide which are saturated by adsorbing a sufficient amount of acetaldehyde is discharged by corona discharge. Acetaldehyde is oxidized by oxygen radicals by applying corona discharge and decomposed into carbon dioxide. Therefore, an increase in the amount of carbon dioxide released from the filter means that the acetaldehyde adsorbed on the filter has been decomposed and the filter surface has been cleaned. By performing discharge with the discharge electrode 15 having discharge or the like, the life of the deodorizing unit 2 can be greatly extended.

以上より、本実施の形態３によれば、ファンにより脱臭部表面に堆積していた塵埃をとばし、コロナ放電等を有する放電電極で放電することにより脱臭部が吸着していた臭気成分を分解するので、脱臭部の寿命を大幅に延ばすことができるという効果を奏する。 As described above, according to the third embodiment, the odor components adsorbed by the deodorizing part are decomposed by removing the dust accumulated on the surface of the deodorizing part by the fan and discharging with the discharge electrode having corona discharge or the like. Therefore, the effect that the lifetime of a deodorizing part can be extended significantly is produced.
