Description

掃除ロボットCleaning robot
　本発明は、床面上を自走する掃除ロボットに関する。 The present invention relates to a cleaning robot that self-propels on a floor surface.
　従来の掃除ロボットは特許文献１及び２に開示されている。これらの掃除ロボットは平面視略円形の本体筐体に駆動輪が設けられ、床面上を自走して掃除を行う。このとき、テーブル等の下方を掃除するために本体筐体は高さの低い薄型に形成される。本体筐体の下面には吸込口が開口し、本体筐体の周面には掃除時の進行方向に対して後方に排気口が開口する。本体筐体内には電動送風機及び集塵部が設けられる。 Conventional cleaning robots are disclosed in Patent Documents 1 and 2. These cleaning robots are provided with a driving wheel in a substantially circular main body housing in a plan view, and perform cleaning by running on the floor surface. At this time, in order to clean the lower part of the table or the like, the main body housing is formed in a thin shape with a low height. A suction port is opened on the lower surface of the main body housing, and an exhaust port is opened on the peripheral surface of the main body housing rearward with respect to the traveling direction during cleaning. An electric blower and a dust collector are provided in the main body casing.
　また、特許文献１に記載の掃除ロボットはイオンを発生するイオン発生装置が本体筐体内に配置されている。イオン発生装置は本体筐体の周面に開口する吐出口に連通したダクト内にイオンを放出する。このダクト内に配置したイオン送風機の駆動によって吐出口からイオンが送出される。 Also, the cleaning robot described in Patent Document 1 has an ion generator for generating ions arranged in the main body casing. The ion generator emits ions into a duct that communicates with a discharge port that opens to the peripheral surface of the main body casing. Ions are sent out from the discharge port by driving an ion blower arranged in the duct.
　上記構成の掃除ロボットにおいて、掃除運転が開始されると駆動輪及び電動送風機が駆動される。本体筐体は駆動輪の回転によって室内の床面上を自走し、電動送風機により吸込口から塵埃を含む気流が吸い込まれる。気流に含まれた塵埃は集塵部で集塵され、塵埃を除去された気流が電動送風機を通過して周面の排気口から後方に排気される。 In the cleaning robot configured as described above, when the cleaning operation is started, the drive wheels and the electric blower are driven. The main body casing is self-propelled on the floor surface of the room by the rotation of the driving wheel, and an air flow including dust is sucked from the suction port by the electric blower. Dust contained in the airflow is collected by the dust collecting section, and the airflow from which the dust has been removed passes through the electric blower and is exhausted backward from the exhaust port on the peripheral surface.
　また、イオン発生装置及びイオン送風機が駆動されると吐出口からイオンが送出され、室内の脱臭や除菌を行うことができる。 Also, when the ion generator and the ion blower are driven, ions are sent out from the discharge port, and indoor deodorization and sterilization can be performed.

　しかしながら、上記従来の掃除ロボットは排気経路が一つであるので、背圧が比較的高くなる可能性がある。これにより、電動送風機による効果的な吸引性能が期待できず、十分な清掃性能を得ることができない虞があるという問題があった。 However, since the conventional cleaning robot has one exhaust path, the back pressure may be relatively high. Thereby, the effective suction performance by an electric blower cannot be expected, and there is a problem that sufficient cleaning performance may not be obtained.
　また、上記従来の掃除ロボットは排気経路が一つであるので、イオンを含む排気とイオンを含まない排気とを分別することができない。これにより、排気口から送出される気流に対して所望の量やタイミングでイオンを放出することが困難になる可能性があるという問題があった。 In addition, since the conventional cleaning robot has a single exhaust path, it is not possible to separate exhaust including ions from exhaust including no ions. As a result, there is a problem that it may be difficult to release ions at a desired amount and timing with respect to the airflow sent from the exhaust port.
　さらに、排気経路が一つであって集塵能力を高める必要があったり、排気音が気になったりする場合、イオンを含む気流の流通経路に集塵フィルタや防音材を取り付けなければならない。これにより、排気に対して放出したイオンが集塵フィルタや防音材に接触して消滅する虞があるという問題があった。 Furthermore, if there is a single exhaust path and it is necessary to increase the dust collection capacity, or if the exhaust noise is a concern, a dust collection filter or soundproof material must be attached to the flow path of the air stream containing ions. Thereby, there existed a problem that the ion discharge | released with respect to exhaust_gas | exhaustion may contact and disappear with a dust collection filter or a soundproof material.
　本発明は、上記の点に鑑みなされたものであり、効果的な吸引によって清掃性能が高められ、さらに室内の脱臭効果や除菌効果の向上を図ることが可能な掃除ロボットを提供することを目的とする。また、排気の清浄化や静音化を高めることが可能な掃除ロボットを提供することを目的とする。 The present invention has been made in view of the above points, and provides a cleaning robot capable of improving cleaning performance by effective suction and further improving indoor deodorizing effect and sterilizing effect. Objective. It is another object of the present invention to provide a cleaning robot capable of enhancing exhaust purification and noise reduction.
　また、上記従来の掃除ロボットは集塵部に堆積した塵埃から臭気が発生する虞がある。これにより、排気口から送出される気流によって室内に臭気が漂うという問題があった。また、堆積した塵埃に水分が含まれる場合、カビや雑菌が発生し易くなる。カビや雑菌はアレルゲンとなることもあるので、掃除ロボットの運転中や塵埃を集塵部から廃棄するときにユーザーが健康を害したり、不快感を覚えたりする可能性があるという問題があった。 Also, the conventional cleaning robot may generate odor from dust accumulated in the dust collecting part. Thereby, there existed a problem that an odor drifted indoors by the airflow sent from an exhaust port. Moreover, when the accumulated dust contains moisture, mold and bacteria are likely to be generated. Molds and bacteria may become allergens, so there is a problem that the user may be injured and feel uncomfortable when operating the cleaning robot or discarding dust from the dust collector. .
　さらに、集塵部に堆積した塵埃には静電気が発生し易くなることがある。これにより、塵埃を集塵部から廃棄するときに塵埃が集塵部に付着して分離し難くなり、廃棄作業が煩わしくなったり、塵埃がユーザーの身体や衣服に付着したり、塵埃が周囲に飛散したりすることがあるといった問題があった。 Furthermore, static electricity may be easily generated in the dust accumulated in the dust collecting part. This makes it difficult for the dust to adhere to the dust collector when it is discarded from the dust collector, making it difficult to dispose of it, attaching dust to the user's body and clothes, and dust to the surroundings. There was a problem that it might be scattered.
　本発明は、上記の点に鑑みなされたものであり、室内の脱臭効果や除菌効果の向上を図ることができるのとともに、集塵部に堆積した塵埃を廃棄するときのユーザーの煩わしさを解消することが可能な掃除ロボットを提供することを目的とする。 The present invention has been made in view of the above points, and can improve the indoor deodorizing effect and the sterilizing effect, and can be annoying to the user when the dust accumulated in the dust collecting portion is discarded. It aims at providing the cleaning robot which can be eliminated.
　上記の課題を解決するため、本発明の掃除ロボットは、吸込口と排気口とを開口して床面上を自走する本体筐体と、前記本体筐体内に配置した電動送風機と、前記電動送風機の駆動によって前記吸込口から吸い込まれた気流の塵埃を集塵する集塵部と、前記電動送風機と前記排気口との間において複数の経路で形成された排気流路と、前記排気流路の少なくとも一の前記経路にイオンを放出するイオン発生装置と、を備えることを特徴としている。 In order to solve the above-described problems, a cleaning robot according to the present invention includes a main body casing that self-runs on a floor surface with an inlet and an exhaust opening, an electric blower disposed in the main body casing, and the electric motor. A dust collecting unit that collects dust of airflow sucked from the suction port by driving of the blower; an exhaust passage formed by a plurality of paths between the electric blower and the exhaust port; and the exhaust passage And an ion generator that emits ions in at least one of the paths.
　この構成によれば、本体筐体は床面上を自走し、電動送風機が駆動されると本体筐体に開口する吸込口から塵埃を含む気流が吸い込まれる。気流に含まれる塵埃は集塵部で集塵される。集塵部で塵埃を除去された気流は電動送風機を通過し、複数の経路の排気流路を通って本体筐体に開口する排気口から排出される。電動送風機を通過した気流は排気流路の少なくとも一の経路でイオン発生装置によってイオンが放出され、排気口から室内に送出される。 According to this configuration, the main body casing runs on the floor surface, and when the electric blower is driven, an airflow including dust is sucked from the suction opening that opens in the main body casing. Dust contained in the airflow is collected by the dust collecting unit. The airflow from which dust has been removed by the dust collecting section passes through the electric blower, and is discharged from an exhaust port that opens to the main body housing through an exhaust passage of a plurality of paths. The airflow that has passed through the electric blower is released by the ion generator through at least one path of the exhaust flow path and is sent into the room from the exhaust port.
　また、上記構成の掃除ロボットにおいて、前記排気流路の複数の前記経路のうちイオンを放出しない前記経路にフィルタを設けたことを特徴としている。 In the cleaning robot having the above-described configuration, a filter is provided in the path that does not release ions among the plurality of paths in the exhaust passage.
　この構成によれば、イオンを含んでいない気流がフィルタを通過して排気口から排出される。これにより、フィルタによってイオンを消滅させることなく、掃除ロボットの排気の清浄化が高められる。 According to this configuration, the airflow not containing ions passes through the filter and is discharged from the exhaust port. This enhances the cleaning of the cleaning robot's exhaust without eliminating the ions by the filter.
　また、上記構成の掃除ロボットにおいて、前記排気流路の複数の前記経路のうちイオンを放出しない前記経路に防音材を設けたことを特徴としている。 Further, in the cleaning robot having the above-described configuration, a soundproof material is provided in the path that does not release ions among the plurality of paths of the exhaust passage.
　この構成によれば、イオンを含んでいない気流が防音材が設けられた箇所を通過して排気口から排出される。これにより、防音材によってイオンを消滅させることなく、掃除ロボットの排気の静音化が高められる。 According to this configuration, the airflow not containing ions passes through the location where the soundproofing material is provided and is discharged from the exhaust port. Thereby, the noise reduction of the exhaust of the cleaning robot can be enhanced without eliminating the ions by the soundproofing material.
　また、上記構成の掃除ロボットにおいて、前記排気流路の複数の前記経路のうちイオンを含む前記経路の気流の流量とイオンを含まない前記経路の気流の流量とを調整可能な第１弁を備えることを特徴としている。 The cleaning robot having the above-described configuration further includes a first valve capable of adjusting a flow rate of the airflow in the path including ions and a flow rate of the airflow in the path not including ions among the plurality of paths in the exhaust flow path. It is characterized by that.
　この構成によれば、第１弁を作動させることで排気口から排出される気流の、イオンを含む気流の流量とイオンを含まない気流の流量とが調整される。これにより、排気口を通して室内に放出されるイオンの量と清浄化及び静音化が高められた排気量とが調整される。 According to this configuration, by operating the first valve, the flow rate of the air flow including ions and the flow rate of the air flow not including ions of the air flow discharged from the exhaust port are adjusted. As a result, the amount of ions released into the room through the exhaust port and the exhaust amount with improved purification and noise reduction are adjusted.
　また、上記構成の掃除ロボットにおいて、前記電動送風機がターボファンで構成され、前記排気流路の複数の前記経路のうちイオンを放出する前記経路が前記ターボファンの吐出方向に沿って延びる向きで形成されていることを特徴としている。 Further, in the cleaning robot having the above-described configuration, the electric blower is configured by a turbo fan, and the path for releasing ions among the plurality of paths of the exhaust passage is formed in a direction extending along a discharge direction of the turbo fan. It is characterized by being.
　この構成によれば、排気流路のイオンを放出する経路がイオン発生装置が設けられた箇所から排気口まで障害なくスムーズに延びるよう形成される。これにより、イオンの消滅が軽減され、イオンがより遠方まで飛散する。 According to this configuration, the path for discharging ions in the exhaust passage is formed so as to smoothly extend from the place where the ion generator is provided to the exhaust port without any obstacles. Thereby, the disappearance of ions is reduced, and ions are scattered farther.
　また、上記構成の掃除ロボットにおいて、前記イオン発生装置がプラスイオンを発生させる電極とマイナスイオンを発生させる電極とを備え、プラスイオンを発生させる前記電極がマイナスイオンを発生させる前記電極より空気流通方向下流側に配置されていることを特徴としている。 Further, in the cleaning robot having the above-described configuration, the ion generator includes an electrode that generates positive ions and an electrode that generates negative ions, and the electrode that generates the positive ions has an air flow direction from the electrode that generates the negative ions. It is characterized by being arranged on the downstream side.
　イオン発生装置に関して、マイナスイオンはプラスイオンと比較して発生量が多く、寿命が長いことが分かっている。したがって、この構成によれば、プラスイオンを発生させる電極がマイナスイオンを発生させる電極より排気口に近くなるので、マイナスイオン、プラスイオンともに室内に送出させ易くなる。 Regarding the ion generator, it is known that negative ions are generated in a larger amount and have a longer life than positive ions. Therefore, according to this configuration, since the electrode for generating positive ions is closer to the exhaust port than the electrode for generating negative ions, both negative ions and positive ions can be easily sent into the room.
　また、上記構成の掃除ロボットにおいて、前記吸込口と前記集塵部との間の吸気流路と前記一の経路とに連通してイオンを含む気流の少なくとも一部を前記集塵部に導く循環流路を備えることを特徴としている。 Further, in the cleaning robot having the above-described configuration, the circulation that leads to at least a part of the airflow including ions in communication with the intake passage and the one path between the suction port and the dust collecting part. A flow path is provided.
　この構成によれば、本体筐体は床面上を自走し、電動送風機が駆動されると本体筐体に開口する吸込口から塵埃を含む気流が吸い込まれる。気流に含まれる塵埃は集塵部で集塵される。集塵部で塵埃を除去された気流は電動送風機を通過し、排気流路でイオン発生装置によってイオンが放出される。イオンを含む気流の一部は本体筐体に開口する排気口から排気され、また一部は循環流路及び吸気流路を通って集塵部に導かれる。 According to this configuration, the main body casing runs on the floor surface, and when the electric blower is driven, an airflow including dust is sucked from the suction opening that opens in the main body casing. Dust contained in the airflow is collected by the dust collecting unit. The airflow from which dust has been removed by the dust collecting section passes through the electric blower, and ions are released by the ion generator in the exhaust passage. A part of the airflow including ions is exhausted from an exhaust port opened in the main body housing, and a part is guided to the dust collecting part through the circulation channel and the intake channel.
　また、上記構成の掃除ロボットにおいて、前記循環流路が前記本体筐体の下面に開口した前記吸込口を通して床面上にイオンを含む気流を吹き付ける向きで前記吸気流路に接続されていることを特徴としている。 Further, in the cleaning robot having the above-described configuration, the circulation flow path is connected to the intake flow path in a direction in which an airflow containing ions is blown onto the floor surface through the suction port opened on the lower surface of the main body housing. It is a feature.
　この構成によれば、イオンを含む気流が吸込口を通して床面上に吹き付けられた後、吸気流路を通って集塵部に導かれる。これにより、イオンが集塵部に導かれるとともに、床面上にも散布される。 According to this configuration, an air stream containing ions is blown onto the floor surface through the suction port, and then guided to the dust collecting section through the intake passage. As a result, the ions are guided to the dust collecting unit and are also scattered on the floor surface.
　また、上記構成の掃除ロボットにおいて、前記排気口側に導かれるイオンを含む気流の流量と前記循環流路に導かれるイオンを含む気流の流量とを調整可能な第２弁を備えることを特徴としている。 Further, the cleaning robot having the above-described configuration further includes a second valve capable of adjusting a flow rate of airflow including ions guided to the exhaust port side and a flow rate of airflow including ions guided to the circulation flow path. Yes.
　この構成によれば、第２弁を作動させることで、排気口側に導かれるイオンを含む気流の流量と循環流路に導かれるイオンを含む気流の流量とが調整される。これにより、排気口を通して室内に放出されるイオンの量と循環流路及び吸気流路を通って集塵部に導かれるイオンの量とが調整される。 According to this configuration, by operating the second valve, the flow rate of the air flow including ions guided to the exhaust port side and the flow rate of the air flow including ions guided to the circulation channel are adjusted. As a result, the amount of ions released into the room through the exhaust port and the amount of ions guided to the dust collector through the circulation channel and the intake channel are adjusted.
　また、上記構成の掃除ロボットにおいて、掃除運転終了後、前記第２弁が前記排気口側に導かれるイオンを含む気流の流量より前記循環流路に導かれるイオンを含む気流の流量のほうが多くなるよう作動することを特徴としている。 Further, in the cleaning robot having the above-described configuration, after the cleaning operation is completed, the flow rate of the airflow including the ions guided to the circulation flow path is larger than the flow rate of the airflow including the ions guided to the exhaust port by the second valve. It is characterized by operating as follows.
　掃除ロボットによる掃除運転が終了されると、集塵部に堆積した塵埃の廃棄作業が近く行われることが予測される。したがって、この構成によれば、廃棄前の塵埃に対して重点的にイオンを含む気流が吹き付けられる。 When the cleaning operation by the cleaning robot is completed, it is predicted that the dust accumulated in the dust collecting part will be disposed of soon. Therefore, according to this structure, the air flow which contains ion preferentially with respect to the dust before disposal is sprayed.
　また、上記構成の掃除ロボットにおいて、掃除ロボットに電力を供給するために前記本体筐体内に配置したバッテリーを備え、前記バッテリーへの充電中に、前記第２弁が前記排気口側に導かれるイオンを含む気流の流量と前記循環流路に導かれるイオンを含む気流の流量とを調整することを特徴としている。 Further, in the cleaning robot having the above configuration, the battery includes a battery disposed in the main body housing for supplying electric power to the cleaning robot, and the second valve is guided to the exhaust port during charging of the battery. And adjusting the flow rate of the air flow including the ions and the flow rate of the air flow including the ions guided to the circulation flow path.
　この構成によれば、バッテリーへの充電中に、排気口を通して室内に放出されるイオンの量と循環流路及び吸気流路を通って集塵部に導かれるイオンの量とが調整される。 According to this configuration, during the charging of the battery, the amount of ions released into the room through the exhaust port and the amount of ions guided to the dust collecting section through the circulation flow path and the intake flow path are adjusted.
　本発明の構成によれば、掃除ロボットは排気流路が複数の経路で形成され、その少なくとも一の経路でイオン発生装置によってイオンが放出されて排気口から室内に送出される。これにより、電動送風機の背圧を比較的低くさせて吸引性能を向上させることができ、排気側の流速を上昇させてイオンを室内に送出させ易くすることが可能である。したがって、効果的な吸引によって清掃性能が高められ、さらに室内の脱臭効果や除菌効果の向上を図ることが可能な掃除ロボットを提供することができる。また、フィルタや防音材によってイオンを消滅させることなく、排気の清浄化や静音化を高めることが可能な掃除ロボットを提供することができる。 According to the configuration of the present invention, the cleaning robot has an exhaust flow path formed by a plurality of paths, and ions are released by the ion generator through at least one of the paths and sent out from the exhaust port to the room. As a result, the suction performance can be improved by lowering the back pressure of the electric blower, and the flow rate on the exhaust side can be increased to facilitate the delivery of ions into the room. Therefore, it is possible to provide a cleaning robot capable of improving the cleaning performance by effective suction and further improving the indoor deodorizing effect and sterilizing effect. In addition, it is possible to provide a cleaning robot capable of enhancing exhaust purification and noise reduction without eliminating ions with a filter or a soundproof material.
　また、本発明の構成によれば、イオンを含む気流の一部は循環流路及び吸気流路を通って集塵部に導かれる。これにより、集塵部に堆積した塵埃の脱臭や除菌を行うことができ、さらに静電気の発生を抑制することができる。したがって、室内の脱臭効果や除菌効果の向上を図ることができるのとともに、集塵部に堆積した塵埃を廃棄するときのユーザーの煩わしさを解消することが可能な掃除ロボットを提供することができる。 In addition, according to the configuration of the present invention, a part of the air flow including ions is guided to the dust collecting part through the circulation flow path and the intake flow path.

　図１に示すように、掃除ロボット１はバッテリー１３により駆動輪５（いずれも図２参照）を駆動して自走する平面視円形の本体筐体２を有している。本体筐体２の上面には集塵部３０（図２参照）を出し入れする際に開閉する蓋部３が設けられている。 As shown in FIG. 1, the cleaning robot 1 has a main body housing 2 having a circular shape in plan view, which drives a driving wheel 5 (both see FIG. 2) by a battery 13 and is self-propelled. A lid 3 that opens and closes when the dust collector 30 (see FIG. 2) is taken in and out is provided on the upper surface of the main body housing 2.
　図２に示すように、本体筐体２には底面から突出する一対の駆動輪５が配置されている。駆動輪５の回転軸は本体筐体２の中心線Ｃ上に配置されている。駆動輪５の両輪が同一方向に回転すると本体筐体２が進退し、逆方向に回転すると本体筐体２が中心線Ｃの回りに回転する。 As shown in FIG. 2, a pair of drive wheels 5 protruding from the bottom surface are arranged on the main body housing 2. The rotational axis of the drive wheel 5 is disposed on the center line C of the main body housing 2. When both wheels of the drive wheel 5 rotate in the same direction, the main body housing 2 moves forward and backward, and when rotated in the opposite direction, the main body housing 2 rotates around the center line C.
　掃除を行う際に移動方向の前方となる本体筐体２の前部には吸込口６が下面に設けられている。吸込口６は本体筐体２の底面に凹設した凹部８の開放面によって床面Ｆに面して形成されている。凹部８内には水平な回転軸で回転する回転ブラシ９が配置され、凹部８の両側方には垂直な回転軸で回転するサイドブラシ１０が配置されている。 A suction port 6 is provided on the lower surface of the front of the main body housing 2 that is in front of the moving direction when cleaning. The suction port 6 is formed so as to face the floor surface F by an open surface of a recess 8 that is recessed in the bottom surface of the main body housing 2. A rotating brush 9 that rotates with a horizontal rotating shaft is disposed in the recess 8, and a side brush 10 that rotates with a vertical rotating shaft is disposed on both sides of the recess 8.
　凹部８の前方にはローラー形状の前輪１５が設けられている。本体筐体２の後端には自在車輪から成る後輪１６が設けられている。前輪１５は通常床面Ｆから離れ、回転ブラシ９、駆動輪５及び後輪１６が床面Ｆに接地して掃除が行われる。前輪１５は進路上に現れた段差に接地し、本体筐体２が段差を容易に乗り越えられるようになっている。 A roller-shaped front wheel 15 is provided in front of the recess 8. A rear wheel 16 composed of a free wheel is provided at the rear end of the main body housing 2. The front wheel 15 is usually separated from the floor surface F, and the rotating brush 9, the drive wheel 5 and the rear wheel 16 are brought into contact with the floor surface F for cleaning. The front wheel 15 contacts the step appearing on the course so that the main body housing 2 can easily get over the step.
　本体筐体２の周面の後端にはバッテリー１３の充電を行う充電端子４が設けられている。本体筐体２は自走して室内に設置される充電台４０に帰還し、充電台４０に設けた端子部４１に充電端子４が接してバッテリー１３を充電する。商用電源に接続される充電台４０は通常、室内の側壁Ｓに沿って設置されている。 A charging terminal 4 for charging the battery 13 is provided at the rear end of the peripheral surface of the main body housing 2. The main body housing 2 is self-propelled and returns to the charging stand 40 installed indoors, and the charging terminal 4 contacts the terminal portion 41 provided on the charging stand 40 to charge the battery 13. The charging stand 40 connected to the commercial power supply is usually installed along the side wall S in the room.
　本体筐体２内には塵埃を集塵する集塵部３０が配置されている。集塵部３０は本体筐体２に設けた集塵室３９内に収納されている。集塵室３９は四方の周面及び底面が覆われた隔離室として形成され、前壁を除く各壁面は閉塞されている。集塵室３９の前壁には凹部８に連通する第１吸気路１１及び凹部８の上方に配置され後述するモータユニット２０に連通する第２吸気路１２が導出されている。 A dust collection unit 30 for collecting dust is disposed in the main body casing 2. The dust collection unit 30 is housed in a dust collection chamber 39 provided in the main body housing 2. The dust collection chamber 39 is formed as an isolation chamber whose four peripheral surfaces and bottom are covered, and each wall surface except the front wall is closed. A first intake passage 11 that communicates with the recess 8 and a second intake passage 12 that is disposed above the recess 8 and communicates with a motor unit 20 described later are led out on the front wall of the dust collection chamber 39.
　集塵部３０は本体筐体２の中心線Ｃ上に配置され、図３に示すように本体筐体２の蓋部３を開いて出し入れすることができる。集塵部３０は有底筒状の集塵容器３１の上面に第１フィルタ３３を有する上部カバー３２が取り付けられている。上部カバー３２は可動の係止部３２ａにより集塵容器３１に係止され、係止部３２ａの操作によって集塵容器３１から取り外すことができる。これにより、集塵容器３１に堆積した塵埃を廃棄することができる。 The dust collecting unit 30 is disposed on the center line C of the main body housing 2 and can be put in and out by opening the lid portion 3 of the main body housing 2 as shown in FIG. The dust collecting unit 30 is provided with an upper cover 32 having a first filter 33 on the upper surface of a bottomed cylindrical dust collecting container 31. The upper cover 32 is locked to the dust collecting container 31 by a movable locking part 32a, and can be detached from the dust collecting container 31 by operating the locking part 32a. Thereby, the dust accumulated in the dust collecting container 31 can be discarded.
　集塵容器３１の周面には先端に流入口３４ａを開口して第１吸気路１１に連通する流入路３４が導出されている。集塵容器３１内には流入路３４に連続して屈曲により下方に気流を導く流入部３４ｂが設けられている。上部カバー３２の周面には先端に流出口３５ａを開口して第２吸気路１２に連通する流出路３５が導出されている。 An inflow passage 34 communicating with the first intake passage 11 is opened on the peripheral surface of the dust collecting container 31 by opening an inflow port 34 a at the tip. In the dust collecting container 31, an inflow portion 34b that guides the airflow downward by bending is provided continuously to the inflow passage 34. On the peripheral surface of the upper cover 32, an outflow path 35 that opens to the front end and communicates with the second intake path 12 is led out.
　流入口３４ａ及び流出口３５ａの周囲には集塵室３９の前壁に密接するパッキン（不図示）が設けられている。これにより、集塵部３０を収納した集塵室３９内が密閉される。集塵室３９の前壁は傾斜面に形成され、集塵部３０の出し入れ時の摺動によるパッキンの劣化を防止することができる。 A packing (not shown) that is in close contact with the front wall of the dust collection chamber 39 is provided around the inlet 34a and the outlet 35a. Thereby, the inside of the dust collection chamber 39 in which the dust collection unit 30 is accommodated is sealed. The front wall of the dust collection chamber 39 is formed on an inclined surface, and deterioration of the packing due to sliding when the dust collection unit 30 is taken in and out can be prevented.
　本体筐体２内の集塵室３９の後方上部には制御基板１４が配置されている。制御基板１４は掃除ロボット１の各部を制御する制御回路が設けられている。集塵室３９の後方の下部には着脱自在のバッテリー１３が配置されている。バッテリー１３は充電端子４を介して充電台４０から充電され、制御基板１４、駆動輪５、回転ブラシ９、サイドブラシ１０及び電動送風機２２等の各部に電力を供給する。 The control board 14 is arranged at the upper rear part of the dust collection chamber 39 in the main body casing 2. The control board 14 is provided with a control circuit for controlling each part of the cleaning robot 1. A detachable battery 13 is disposed in the lower part of the rear of the dust collection chamber 39. The battery 13 is charged from the charging stand 40 via the charging terminal 4 and supplies power to the control board 14, the drive wheel 5, the rotating brush 9, the side brush 10, the electric blower 22, and the like.
　本体筐体２の前部にはモータユニット２０が配置されている。モータユニット２０は樹脂成形品のハウジング２１とハウジング２１内に収納される電動送風機２２とを備えている。ハウジング２１は電動送風機２２の吸気側において第２吸気路１２に連通し、電動送風機２２の排気側において本体筐体２の上面に設けた排気口７（図２参照）に連通している。そして、排気口７から矢印Ａ３に示すように上方後方に向けて斜め方向に気流が排気される。 The motor unit 20 is disposed at the front of the main body housing 2. The motor unit 20 includes a housing 21 of a resin molded product and an electric blower 22 accommodated in the housing 21. The housing 21 communicates with the second intake passage 12 on the intake side of the electric blower 22 and communicates with the exhaust port 7 (see FIG. 2) provided on the upper surface of the main body housing 2 on the exhaust side of the electric blower 22. Then, the air flow is exhausted from the exhaust port 7 in an oblique direction toward the upper rear as indicated by an arrow A3.
　続いて、モータユニット２０の構成について、図２に加えて図４～図９を用いてさらに詳しく説明する。図４、図５及び図６はモータユニット２０の斜視図、正面図及び上面図である。図７は図５及び図６に示すモータユニット２０のＶII－ＶII線で切断した斜視図、図８は図５及び図６に示すモータユニット２０のVIII－VIII線における垂直断面側面図である。図９は掃除ロボット１の排気流路周辺の構成を示すブロック図である。 Subsequently, the configuration of the motor unit 20 will be described in more detail with reference to FIGS. 4 to 9 in addition to FIG. 4, 5, and 6 are a perspective view, a front view, and a top view of the motor unit 20. 7 is a perspective view of the motor unit 20 shown in FIGS. 5 and 6 cut along the line VII-VII, and FIG. 8 is a vertical sectional side view of the motor unit 20 shown in FIGS. FIG. 9 is a block diagram showing a configuration around the exhaust flow path of the cleaning robot 1.
　図４～図６に示すモータユニット２０は前述のように樹脂成形品のハウジング２１とハウジング２１内に収納される電動送風機２２とを備えている。電動送風機２２はモータケース２２ａで覆われたターボファンにより形成される。 The motor unit 20 shown in FIGS. 4 to 6 includes the housing 21 made of a resin molded product and the electric blower 22 accommodated in the housing 21 as described above. The electric blower 22 is formed by a turbo fan covered with a motor case 22a.
　電動送風機２２のモータケース２２ａには軸方向の一端に吸気口（不図示）が開口し、周面の２箇所に排気口（不図示）が開口している。ハウジング２１の前面にはモータケース２２ａの吸気口に対向して開口部２３が設けられている。ハウジング２１の電動送風機２２の両側方にはモータケース２２ａの各排気口にそれぞれ連通する第１排気路２４ａ及び第２排気路２４ｂが設けられている。第１、第２排気路２４ａ、２４ｂは電動送風機２２と排気口７との間における複数の経路として形成された排気流路であって、本体筐体２の上面に設けた排気口７（図２参照）に連通している。 In the motor case 22a of the electric blower 22, an air inlet (not shown) is opened at one end in the axial direction, and an air outlet (not shown) is opened at two locations on the peripheral surface. An opening 23 is provided on the front surface of the housing 21 so as to face the air inlet of the motor case 22a. A first exhaust path 24a and a second exhaust path 24b communicating with the exhaust ports of the motor case 22a are provided on both sides of the electric blower 22 of the housing 21, respectively. The first and second exhaust passages 24a and 24b are exhaust passages formed as a plurality of paths between the electric blower 22 and the exhaust port 7, and the exhaust ports 7 (see FIG. 2).
　第１排気路２４ａには一対の電極２５ａ、２５ｂを有したイオン発生装置２５が配置されている。電極２５ａ、２５ｂには交流波形またはインパルス波形から成る電圧が印加され、電極２５ａ、２５ｂのコロナ放電により生成されたイオンが第１排気路２４ａ、すなわちに排気流路の一つの経路に放出される。 An ion generator 25 having a pair of electrodes 25a and 25b is disposed in the first exhaust path 24a. A voltage having an AC waveform or an impulse waveform is applied to the electrodes 25a and 25b, and ions generated by corona discharge of the electrodes 25a and 25b are discharged to the first exhaust path 24a, that is, one path of the exhaust path. .
　一方の電極２５ｂには正電圧が印加され、コロナ放電による水素イオンが空気中の水分と結合して主としてＨ＋（Ｈ２Ｏ）ｍから成るプラスイオンを発生する。他方の電極２５ａには負電圧が印加され、コロナ放電による酸素イオンが空気中の水分と結合して主としてＯ２ －（Ｈ２Ｏ）ｎから成るマイナスイオンを発生する。ここで、ｍ、ｎは任意の自然数である。Ｈ＋（Ｈ２Ｏ）ｍ及びＯ２ －（Ｈ２Ｏ）ｎは空気中の浮遊菌や臭い成分の表面で凝集してこれらを取り囲む。 A positive voltage is applied to one electrode 25b, and hydrogen ions generated by corona discharge combine with moisture in the air to generate positive ions mainly composed of H + (H 2 O) m. A negative voltage is applied to the other electrode 25a, and oxygen ions generated by corona discharge combine with moisture in the air to generate negative ions mainly composed of O 2 − (H 2 O) n. Here, m and n are arbitrary natural numbers. H + (H 2 O) m and O 2 − (H 2 O) n aggregate around the surface of airborne bacteria and odorous components and surround them.
　そして、式（１）～（３）に示すように、衝突により活性種である［・ＯＨ］（水酸基ラジカル）やＨ２Ｏ２（過酸化水素）を微生物等の表面上で凝集生成して浮遊菌や臭い成分を破壊する。ここで、ｍ’、ｎ’は任意の自然数である。従って、プラスイオン及びマイナスイオンを発生して排気口７（図２参照）から送出することにより室内の除菌及び脱臭を行うことができる。 Then, as shown in the formulas (1) to (3), active species [· OH] (hydroxyl radicals) and H 2 O 2 (hydrogen peroxide) are agglomerated and produced on the surface of microorganisms or the like by collision. Destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers. Therefore, it is possible to sterilize and deodorize the room by generating positive ions and negative ions and sending them out from the exhaust port 7 (see FIG. 2).

→ H 2 O 2 + O 2 + (m + m ′ + n + n ′) H 2 O (3)
　また、第１排気路２４ａは電動送風機２２であるターボファンのモータケース２２ａの一方の排気口からの吐出方向Ａ５ａ（図７参照）に沿って延びる向きで形成されている。このターボファンの吐出方向Ａ５ａ、すなわち空気の流通方向に関して、図７に示すようにプラスイオンを発生させる電極２５ｂがマイナスイオンを発生させる電極２５ａより空気流通方向下流側に配置されている。 The first exhaust passage 24a is formed in a direction extending along the discharge direction A5a (see FIG. 7) from one exhaust port of the motor case 22a of the turbofan which is the electric blower 22. With respect to the discharge direction A5a of the turbofan, that is, the air flow direction, as shown in FIG. 7, the electrode 25b that generates positive ions is disposed downstream of the electrode 25a that generates negative ions in the air flow direction.
　一方、第１排気路２４ｂはモータケース２２ａの他方の排気口からの吐出方向Ａ５ｂとは異なる向きで形成されている。下方に向かう吐出方向Ａ５ｂに対して、第１排気路２４ｂは上方に向かって延びている。 On the other hand, the first exhaust path 24b is formed in a direction different from the discharge direction A5b from the other exhaust port of the motor case 22a. The first exhaust path 24b extends upward with respect to the downward discharge direction A5b.
　図４～図８には図示していないが、図９に示すように、第２排気路２４ｂには第２フィルタ５０及び防音材５１が設けられている。第２フィルタ５０はＨＥＰＡフィルタなどで構成され、第２排気路２４ｂの空気流通路を覆うように取り付けられている。防音材５１はグラスウールやウレタン樹脂などで構成され、第２排気路２４ｂの内面或いは外面に貼付されている。 Although not shown in FIGS. 4 to 8, as shown in FIG. 9, a second filter 50 and a soundproof material 51 are provided in the second exhaust passage 24b. The second filter 50 is composed of a HEPA filter or the like, and is attached so as to cover the air flow passage of the second exhaust passage 24b. The soundproof material 51 is made of glass wool, urethane resin, or the like, and is attached to the inner surface or the outer surface of the second exhaust path 24b.
　また、図１０に示すように、第１排気路２４ａと第２排気路２４ｂとにそれぞれ第１弁２６が設けられている。第１弁２６は制御基板１４から受信する制御信号に基づいて作動する。第１弁２６を用いることにより、イオンを含む第１排気路２４ａの気流の流量とイオンを含まない第２排気路２４ｂの気流の流量との調整が可能である。 Further, as shown in FIG. 10, a first valve 26 is provided in each of the first exhaust path 24a and the second exhaust path 24b. The first valve 26 operates based on a control signal received from the control board 14. By using the first valve 26, it is possible to adjust the flow rate of the air flow in the first exhaust passage 24a containing ions and the flow rate of the air flow in the second exhaust passage 24b not containing ions.
　設定により、掃除ロボット１は掃除運転終了後やバッテリー１３への充電中に、電動送風機２２が駆動している状態で第１弁２６を作動させてイオンを含む第１排気路２４ａの気流の流量とイオンを含まない第２排気路２４ｂの気流の流量とを調整することができる。 Depending on the setting, the cleaning robot 1 operates the first valve 26 in a state where the electric blower 22 is driven after the cleaning operation is completed or during the charging of the battery 13, and the flow rate of the air flow in the first exhaust path 24 a containing ions. And the flow rate of the air flow in the second exhaust path 24b not containing ions can be adjusted.
　上記構成の掃除ロボット１において、掃除運転が指示されると、電動送風機２２、イオン発生装置２５、駆動輪５、回転ブラシ９及びサイドブラシ１０が駆動される。これにより、本体筐体２は回転ブラシ９、駆動輪５及び後輪１６が床面Ｆに接地して所定の範囲を自走し、吸込口６から床面Ｆの塵埃を含む気流を吸い込む。このとき、回転ブラシ９の回転によって床面Ｆ上の塵埃が掻き上げられて凹部８内に導かれる。また、サイドブラシ１０の回転によって吸込口６の側方の塵埃が吸込口６に導かれる。 In the cleaning robot 1 having the above configuration, when a cleaning operation is instructed, the electric blower 22, the ion generator 25, the drive wheel 5, the rotating brush 9, and the side brush 10 are driven. As a result, the main body housing 2 makes the rotating brush 9, the drive wheel 5 and the rear wheel 16 ground on the floor surface F and self-travels within a predetermined range, and sucks an airflow including dust on the floor surface F from the suction port 6. At this time, the dust on the floor surface F is scraped up by the rotation of the rotating brush 9 and guided into the recess 8. Further, the dust on the side of the suction port 6 is guided to the suction port 6 by the rotation of the side brush 10.
　吸込口６から吸い込まれた気流は矢印Ａ１に示すように第１吸気路１１を後方に流通し、流入口３４ａを介して集塵部３０に流入する。集塵部３０に流入した気流は第１フィルタ３３により塵埃が捕集され、流出口３５ａを介して集塵部３０から流出する。これにより、集塵容器３１内に塵埃が集塵して堆積する。集塵部３０から流出した気流は矢印Ａ２に示すように第２吸気路１２を前方に流通し、開口部２３を介してモータユニット２０の電動送風機２２に流入する。 The air flow sucked from the suction port 6 flows backward through the first air intake passage 11 as shown by an arrow A1, and flows into the dust collecting unit 30 through the inlet 34a. The airflow flowing into the dust collecting unit 30 is collected by the first filter 33 and flows out from the dust collecting unit 30 through the outlet 35a. Thereby, dust is collected and accumulated in the dust collecting container 31. The airflow flowing out from the dust collection unit 30 flows forward through the second intake passage 12 as indicated by an arrow A2, and flows into the electric blower 22 of the motor unit 20 through the opening 23.
　電動送風機２２を通過した気流は第１排気路２４ａ及び第２排気路２４ｂを流通する。第１排気路２４ａを流通する気流はイオン発生装置２５が放出するイオンを含み、矢印Ａ３ａで示すように排気口７に向かって流通する。第２排気路２４ｂを流通する気流はイオンを含むことなく第２フィルタ５０により塵埃が捕集され、防音材５１によって静音化されて矢印Ａ３ｂで示すように排気口７に向かって流通する。 The airflow that has passed through the electric blower 22 flows through the first exhaust path 24a and the second exhaust path 24b. The airflow flowing through the first exhaust path 24a includes ions released by the ion generator 25 and flows toward the exhaust port 7 as indicated by an arrow A3a. The airflow flowing through the second exhaust path 24b does not contain ions, dust is collected by the second filter 50, is silenced by the soundproofing material 51, and flows toward the exhaust port 7 as indicated by an arrow A3b.
　そして、本体筐体２の上面に設けた排気口７から矢印Ａ３に示すように上方後方に向けて斜め方向にイオンを含む気流が排気される。これにより、室内の掃除が行われるとともに、自走する本体筐体２の排気に含まれるイオンが室内に行き渡って室内の除菌や脱臭が行われる。このとき、排気口７から上方に向けて排気するので、床面Ｆの塵埃の巻き上げを防止して室内の清浄度を向上することができる。 Then, an air flow containing ions in an oblique direction is exhausted upward and rearward from an exhaust port 7 provided on the upper surface of the main body housing 2 as indicated by an arrow A3. As a result, the room is cleaned, and ions contained in the exhaust of the self-propelled main body casing 2 are distributed into the room to be sterilized and deodorized in the room. At this time, since the air is exhausted upward from the exhaust port 7, it is possible to prevent the dust on the floor surface F from being rolled up and improve the cleanliness of the room.
　また、駆動輪５の両輪を互いに逆方向に回転すると本体筐体２が中心線Ｃを中心に回転して向きを変える。これにより、所望の範囲全体に本体筐体２を自走させるとともに障害物を避けて自走させることができる。なお、駆動輪５の両輪を前進時に対して反転して本体筐体２を後退させても良い。 Also, when both wheels of the drive wheel 5 are rotated in opposite directions, the main body housing 2 rotates around the center line C and changes its direction. Thereby, while making the main body housing | casing 2 self-propelled to the whole desired range, an obstacle can be avoided and self-propelled. The main body housing 2 may be moved backward by reversing both wheels of the drive wheel 5 with respect to the forward movement.
　掃除が終了すると、本体筐体２は自走して充電台４０に帰還する。これにより、充電端子４が端子部４１に接してバッテリー１３が充電される。設定により、掃除ロボット１は掃除運転終了後やバッテリー１３への充電中に、電動送風機２２が駆動している状態でイオン発生装置２５及び第１弁２６を作動させてイオンを含む第１排気路２４ａの気流の流量とイオンを含まない第２排気路２４ｂの気流の流量とを調整することができる。 When cleaning is completed, the main body housing 2 self-propels and returns to the charging stand 40. Thereby, the charging terminal 4 contacts the terminal part 41 and the battery 13 is charged. Depending on the setting, the cleaning robot 1 operates the ion generator 25 and the first valve 26 in a state where the electric blower 22 is driven after the cleaning operation is completed or during charging of the battery 13, and the first exhaust path including ions. It is possible to adjust the flow rate of the air flow 24a and the flow rate of the air flow in the second exhaust passage 24b not including ions.
　上記のように、掃除ロボット１は電動送風機２２と排気口７との間において第１排気路２４ａと第２排気路２４ｂとで形成された排気流路を備えているので、電動送風機２２の背圧を比較的低くさせて吸引性能を向上させることができる。また、掃除ロボット１は排気流路の一つの経路である第１排気路２４ａにイオンを放出するイオン発生装置２５を備えているので、電動送風機２２を通過した気流が第１排気路２４ａでイオンが放出されて排気口７から室内に送出される。したがって、排気側の流速を上昇させてイオンを室内に送出させ易くすることが可能である。 As described above, the cleaning robot 1 includes the exhaust passage formed by the first exhaust passage 24 a and the second exhaust passage 24 b between the electric blower 22 and the exhaust port 7. The suction performance can be improved by lowering the pressure. In addition, since the cleaning robot 1 includes the ion generator 25 that emits ions to the first exhaust path 24a that is one path of the exhaust flow path, the airflow that has passed through the electric blower 22 is ionized in the first exhaust path 24a. Is discharged and sent from the exhaust port 7 into the room. Therefore, it is possible to increase the flow rate on the exhaust side and facilitate the delivery of ions into the room.
　なお、排気流路の経路を複数形成すると、排気経路が一つである場合と比較して、複数のうちの一つ当たりの排気経路の断面積が小さくなる。これにより、排気の流速を一層速くすることができる。そして、その排気経路の一つにイオンを放出できるようイオン発生装置を設けることで、より遠くまでイオンを飛散させることが可能である。 In addition, when a plurality of exhaust passage paths are formed, the cross-sectional area of the exhaust path per one of the plurality of exhaust passages is smaller than when there is a single exhaust path. Thereby, the flow velocity of exhaust gas can be further increased. Then, by providing an ion generator so that ions can be released in one of the exhaust paths, ions can be scattered farther.
　また、掃除ロボット１は排気流路の複数の経路のうちイオンを放出しない第２排気路２４ｂに第２フィルタ５０が設けられているので、イオンを含んでいない気流が第２フィルタ５０を通過して排気口７から排出される。したがって、フィルタによってイオンを消滅させることなく、掃除ロボット１の排気の清浄化を高めることができる。 In addition, since the cleaning filter 1 is provided with the second filter 50 in the second exhaust path 24b that does not release ions among the plurality of paths of the exhaust flow path, the air flow not containing ions passes through the second filter 50. And is discharged from the exhaust port 7. Therefore, the cleaning of the exhaust of the cleaning robot 1 can be enhanced without eliminating the ions by the filter.
　また、掃除ロボット１は排気流路の複数の経路のうちイオンを放出しない第２排気路２４ｂに防音材５１が設けられているので、イオンを含んでいない気流が防音材５１が設けられた箇所を通過して排気口７から排出される。これにより、防音材によってイオンを消滅させることなく、掃除ロボット１の排気の静音化を高めることができる。 In addition, since the cleaning robot 1 is provided with the soundproof material 51 in the second exhaust path 24b that does not release ions among the plurality of paths of the exhaust flow path, the airflow that does not include ions is provided at the position where the soundproof material 51 is provided. Through the exhaust port 7. Thereby, the noise reduction of the exhaust of the cleaning robot 1 can be enhanced without eliminating the ions by the soundproofing material.
　また、掃除ロボット１は排気流路の複数の経路のうちイオンを含む第１排気路２４ａの気流の流量とイオンを含まない第２排気路２４ｂの気流の流量とを調整可能な第１弁２６を備えているので、第１弁２６を作動させることで排気口７から排出される気流の、イオンを含む気流の流量とイオンを含まない気流の流量とが調整される。したがって、排気口７を通して室内に放出されるイオンの量と清浄化及び静音化が高められた排気量とを調整することができる。 Further, the cleaning robot 1 can adjust the flow rate of the air flow in the first exhaust path 24a including ions and the flow rate of the air flow in the second exhaust path 24b not including ions among the plurality of paths of the exhaust flow path. Therefore, by operating the first valve 26, the flow rate of the air flow including ions and the flow rate of the air flow not including ions of the air flow discharged from the exhaust port 7 are adjusted. Therefore, it is possible to adjust the amount of ions released into the room through the exhaust port 7 and the exhaust amount with improved purification and noise reduction.
　また、掃除ロボット１は電動送風機２２がターボファンで構成され、排気流路の複数の経路のうちイオンを放出する第１排気路２４ａがターボファンの吐出方向Ａ５ａに沿って延びる向きで形成されているので、第１排気路２４ａがイオン発生装置２５が設けられた箇所から排気口７まで障害なくスムーズに延びる。したがって、イオンの消滅を軽減させることができ、イオンをより遠方まで飛散させることが可能である。 In the cleaning robot 1, the electric blower 22 is configured by a turbo fan, and a first exhaust path 24 a that discharges ions among a plurality of paths of the exhaust path is formed in a direction extending along the discharge direction A 5 a of the turbo fan. Therefore, the first exhaust path 24a extends smoothly from the location where the ion generator 25 is provided to the exhaust port 7 without any obstacles. Therefore, the disappearance of ions can be reduced, and ions can be scattered farther.
　なお、イオン発生装置２５に関して、マイナスイオンはプラスイオンと比較して発生量が多く、寿命が長いことが分かっている。そこで、掃除ロボット１はイオン発生装置２５のプラスイオンを発生させる電極２５ｂをマイナスイオンを発生させる電極２５ａより空気流通方向下流側に配置させているので、プラスイオンを発生させる電極２５ｂがマイナスイオンを発生させる電極２５ａより排気口７に近くなる。したがって、マイナスイオン、プラスイオンともに室内に送出させ易くすることができる。 In addition, regarding the ion generator 25, it is known that negative ions are generated in a larger amount and have a longer lifetime than positive ions. Therefore, the cleaning robot 1 arranges the electrode 25b for generating positive ions of the ion generator 25 on the downstream side in the air flow direction from the electrode 25a for generating negative ions, so that the electrode 25b for generating positive ions generates negative ions. It is closer to the exhaust port 7 than the electrode 25a to be generated. Therefore, both negative ions and positive ions can be easily sent into the room.
　そして、本発明の上記実施形態の構成によれば、掃除ロボット１は排気流路が複数の経路で形成され、その第１排気路２４ａでイオン発生装置２５によってイオンが放出されて排気口７から室内に送出される。これにより、電動送風機２２の背圧を比較的低くさせて吸引性能を向上させることができ、排気側の流速を上昇させてイオンを室内に送出させ易くすることが可能である。したがって、効果的な吸引によって清掃性能が高められ、さらに室内の脱臭効果や除菌効果の向上を図ることが可能な掃除ロボット１を提供することができる。また、第２フィルタ５０や防音材５１によってイオンを消滅させることなく、排気の清浄化や静音化を高めることが可能な掃除ロボット１を提供することができる。 According to the configuration of the above embodiment of the present invention, the cleaning robot 1 has an exhaust flow path formed by a plurality of paths, and ions are released by the ion generator 25 in the first exhaust path 24a and are discharged from the exhaust port 7. It is sent out indoors. Thereby, the back pressure of the electric blower 22 can be made relatively low to improve the suction performance, and the flow rate on the exhaust side can be increased to make it easier to send ions into the room. Therefore, it is possible to provide the cleaning robot 1 which can improve the cleaning performance by effective suction and can further improve the deodorizing effect and the sterilizing effect in the room. Further, it is possible to provide the cleaning robot 1 capable of enhancing exhaust purification and noise reduction without causing the second filter 50 and the soundproofing material 51 to eliminate ions.
　次に、本発明の第２実施形態に係る掃除ロボットについて、図１０～図１５を用いて説明する。図１０は掃除ロボットのモータユニットの斜視図、図１１は掃除ロボットのモータユニットの正面図、図１２は図１１に示すモータユニットのＸII－ＸII線で切断した斜視図、図１３は図１１に示すモータユニットのXIII－XIII線における垂直断面側面図、図１４は掃除ロボットの垂直断面部分側面図、図１５は掃除ロボットの排気流路周辺の構成を示すブロック図である。なお、この実施形態の基本的な構成は図１～図９を用いて説明した前記第１実施形態と同じであるので、第１実施形態と共通する構成要素には前と同じ符号を付し、図面の記載及びその説明を省略するものとする。 Next, a cleaning robot according to a second embodiment of the present invention will be described with reference to FIGS. 10 is a perspective view of the motor unit of the cleaning robot, FIG. 11 is a front view of the motor unit of the cleaning robot, FIG. 12 is a perspective view of the motor unit shown in FIG. 11 cut along line XII-XII, and FIG. 14 is a vertical sectional side view taken along line XIII-XIII of the motor unit shown in FIG. 14, FIG. 14 is a vertical sectional partial side view of the cleaning robot, and FIG. 15 is a block diagram showing a configuration around the exhaust passage of the cleaning robot. Since the basic configuration of this embodiment is the same as that of the first embodiment described with reference to FIGS. 1 to 9, the same components as those of the first embodiment are denoted by the same reference numerals as before. The description of the drawings and the description thereof will be omitted.
　第２実施形態の掃除ロボット１は、図１０～図１２に示すように第１排気路２４ａの下部には後方に向かって開口した循環路２７が設けられている。循環路２７は開口面２７ａが凹部８（図１３及び図１４参照）の壁面に沿った曲面に形成されている。これにより、図１４に示すように、循環路２７は凹部８の壁面に設けた孔部８ａを介して凹部８に連通するとともに、回転ブラシ９にイオンを含む気流を吹き付ける向きで凹部８に接続されている。そして、循環路２７は第１排気路２４ａを流通するイオンを含む気流の一部を吸気側に導く。すなわち、循環路２７は吸込口６と集塵部３０との間の吸気流路である凹部８及び第１吸気路１１と、電動送風機２２と排気口７との間の排気流路である第１排気路２４ａとに連通してイオンを含む気流の一部を集塵部３０に導く循環流路として構成されている。 In the cleaning robot 1 of the second embodiment, as shown in FIGS. 10 to 12, a circulation path 27 that opens rearward is provided at the lower portion of the first exhaust path 24a. In the circulation path 27, the opening surface 27a is formed in a curved surface along the wall surface of the recess 8 (see FIGS. 13 and 14). Thereby, as shown in FIG. 14, the circulation path 27 communicates with the recess 8 through the hole 8 a provided in the wall surface of the recess 8, and is connected to the recess 8 in a direction in which an air stream containing ions is blown to the rotating brush 9. Has been. Then, the circulation path 27 guides a part of the airflow including ions flowing through the first exhaust path 24a to the intake side. In other words, the circulation path 27 is a recess 8 and a first intake path 11 that are intake passages between the suction port 6 and the dust collecting part 30, and an exhaust passage that is between the electric blower 22 and the exhaust port 7. It is configured as a circulation flow path that communicates with one exhaust path 24 a and guides a part of the airflow including ions to the dust collection unit 30.
　図１０～図１４には図示していないが、図１５に示すように、第１排気路２４ａと循環路２７とにそれぞれ第２弁２８が設けられている。第２弁２８は制御基板１４から受信する制御信号に基づいて作動する。第２弁２８を用いることにより、排気口７側に導かれるイオンを含む気流の流量と循環路２７に導かれるイオンを含む気流の流量との調整が可能である。 Although not shown in FIGS. 10 to 14, as shown in FIG. 15, second valves 28 are provided in the first exhaust passage 24a and the circulation passage 27, respectively. The second valve 28 operates based on a control signal received from the control board 14. By using the second valve 28, it is possible to adjust the flow rate of the air flow including ions guided to the exhaust port 7 side and the flow rate of the air flow including ions guided to the circulation path 27.
　設定により、掃除ロボット１は掃除運転終了後、電動送風機２２が駆動している状態で排気口７側に導かれるイオンを含む気流の流量より循環路２７に導かれるイオンを含む気流の流量のほうが多くなるよう第２弁２８を作動させることができる。 Depending on the setting, after the cleaning operation is completed, the cleaning robot 1 has a flow rate of airflow including ions guided to the circulation path 27 rather than a flow rate of airflow including ions guided to the exhaust port 7 in a state where the electric blower 22 is driven. The second valve 28 can be actuated to increase.
　また、設定により、掃除ロボット１はバッテリー１３への充電中に、第２弁２８を作動させて排気口７側に導かれるイオンを含む気流の流量と循環路２７に導かれるイオンを含む気流の流量とを調整することもできる。 In addition, depending on the setting, the cleaning robot 1 operates the second valve 28 during charging of the battery 13, and the flow rate of the airflow including ions guided to the exhaust port 7 and the airflow including the ions guided to the circulation path 27. The flow rate can also be adjusted.
　上記構成の掃除ロボット１において、掃除運転が指示されると、電動送風機２２、イオン発生装置２５、駆動輪５、回転ブラシ９及びサイドブラシ１０が駆動される。これにより、本体筐体２は所定の範囲を自走しながら吸込口６から床面Ｆの塵埃を含む気流を吸い込み、塵埃が集塵部３０に捕集される。集塵部３０から流出した気流は電動送風機２２を通過して第１排気路２４ａ及び第２排気路２４ｂを流通する。 In the cleaning robot 1 having the above configuration, when a cleaning operation is instructed, the electric blower 22, the ion generator 25, the drive wheel 5, the rotating brush 9, and the side brush 10 are driven. As a result, the main body housing 2 sucks in an air flow including dust on the floor surface F from the suction port 6 while traveling in a predetermined range, and the dust is collected in the dust collecting portion 30. The airflow flowing out from the dust collection unit 30 passes through the electric blower 22 and flows through the first exhaust path 24a and the second exhaust path 24b.
　第１排気路２４ａを流通する気流にはイオン発生装置２５が放出するイオンが含まれる。そして、本体筐体２の上面に設けた排気口７から矢印Ａ３に示すように上方後方に向けて斜め方向にイオンを含む気流が排気される。 The airflow flowing through the first exhaust path 24a includes ions released by the ion generator 25. Then, an air flow containing ions in an oblique direction is exhausted upward and rearward from an exhaust port 7 provided on the upper surface of the main body housing 2 as indicated by an arrow A3.
　第１排気路２４ａを流通する気流の一部は矢印Ａ４に示すように循環路２７を介して凹部８に導かれる。このため、吸込口６から第１吸気路１１に導かれる気流内にイオンが含まれる。 A part of the airflow flowing through the first exhaust path 24a is guided to the recess 8 through the circulation path 27 as indicated by an arrow A4. For this reason, ions are included in the airflow guided from the suction port 6 to the first intake passage 11.
　掃除が終了すると、本体筐体２は自走して充電台４０に帰還する。これにより、充電端子４が端子部４１に接してバッテリー１３が充電される。設定により、掃除ロボット１は掃除運転終了後やバッテリー１３への充電中に、電動送風機２２が駆動している状態でイオン発生装置２５及び第２弁２８を作動させて排気口７側に導かれるイオンを含む気流の流量と循環路２７に導かれるイオンを含む気流の流量とを調整することができる。 When cleaning is completed, the main body housing 2 self-propels and returns to the charging stand 40. Thereby, the charging terminal 4 contacts the terminal part 41 and the battery 13 is charged. Depending on the setting, the cleaning robot 1 is guided to the exhaust port 7 side by operating the ion generator 25 and the second valve 28 while the electric blower 22 is driven after the cleaning operation is completed or the battery 13 is being charged. The flow rate of the air flow containing ions and the flow rate of the air flow containing ions guided to the circulation path 27 can be adjusted.
　上記のように、掃除ロボット１は凹部８及び第１吸気路１１と、第１排気路２４ａとに連通してイオンを含む気流の一部を集塵部３０に導く循環路２７を備えているので、イオンを含む気流の一部が循環路２７、凹部８及び第１吸気路１１を通って集塵部３０に導かれる。したがって、集塵部３０に堆積した塵埃の脱臭や除菌を行うことができ、さらに静電気の発生を抑制することができる。 As described above, the cleaning robot 1 includes the circulation path 27 that communicates with the recess 8, the first intake path 11, and the first exhaust path 24 a and guides a part of the airflow including ions to the dust collection unit 30. Therefore, a part of the air flow including ions is guided to the dust collection unit 30 through the circulation path 27, the recess 8, and the first intake path 11. Therefore, it is possible to deodorize and disinfect the dust accumulated on the dust collection unit 30 and to suppress the generation of static electricity.
　また、掃除ロボット１は排気口７側に導かれるイオンを含む気流の流量と循環路２７に導かれるイオンを含む気流の流量とを調整可能な第２弁２８を備えているので、排気口７を通して室内に放出されるイオンの量と循環路２７、凹部８及び第１吸気路１１を通って集塵部３０に導かれるイオンの量とが調整される。したがって、所望のイオン量、タイミングで気流を集塵部３０に導くことができ、集塵部３０に堆積した塵埃の脱臭や除菌、静電気の発生を抑制する作用を向上させることが可能になる。 In addition, the cleaning robot 1 includes the second valve 28 that can adjust the flow rate of the airflow including ions guided to the exhaust port 7 side and the flow rate of the airflow including ions guided to the circulation path 27. The amount of ions released into the room through and the amount of ions guided to the dust collection unit 30 through the circulation path 27, the recess 8 and the first intake path 11 are adjusted. Therefore, the air flow can be guided to the dust collecting unit 30 at a desired ion amount and timing, and it is possible to improve the action of suppressing the deodorization and sterilization of the dust accumulated in the dust collecting unit 30 and the generation of static electricity. .
　また、掃除ロボット１は掃除運転終了後、電動送風機２２が駆動している状態で第２弁２８が排気口７側に導かれるイオンを含む気流の流量より循環路２７に導かれるイオンを含む気流の流量のほうが多くなるよう作動するので、廃棄前の塵埃に対して重点的にイオンを含む気流が吹き付けられる。したがって、廃棄前の塵埃に対して脱臭や除菌、静電気の発生を抑制する作用を向上させることができ、塵埃の廃棄作業中に室内に臭気が漂ったり、塵埃が飛散したりすることを妨げることが可能になる。 In addition, after the cleaning operation is completed, the cleaning robot 1 has the air flow including the ions guided to the circulation path 27 from the flow rate of the air flow including the ions guided to the exhaust port 7 by the second valve 28 while the electric blower 22 is driven. Therefore, the air flow containing ions is focused on the dust before disposal. Therefore, it is possible to improve the effect of suppressing deodorization, sterilization, and generation of static electricity with respect to dust before disposal, and prevent odors and dust from scattering inside the room during dust disposal. It becomes possible.
　また、掃除ロボット１はバッテリー１３への充電中に、第２弁２８が排気口７側に導かれるイオンを含む気流の流量と循環流２６に導かれるイオンを含む気流の流量とを調整するので、充電中に室内に放出されるイオンの量と集塵部３０に導かれるイオンの量とが調整される。したがって、充電中に所望のイオン量、タイミングで気流を集塵部３０に導くことができ、集塵部３０に堆積した塵埃の脱臭や除菌、静電気の発生を抑制する作用を向上させることが可能になる。 In addition, the cleaning robot 1 adjusts the flow rate of the airflow including the ions guided to the exhaust port 7 and the flow rate of the airflow including the ions guided to the circulation flow 26 while the battery 13 is charged. The amount of ions released into the room during charging and the amount of ions guided to the dust collection unit 30 are adjusted. Therefore, the airflow can be guided to the dust collecting unit 30 at a desired ion amount and timing during charging, and the effect of suppressing deodorization and sterilization of dust accumulated on the dust collecting unit 30 and generation of static electricity can be improved. It becomes possible.
　そして、本発明の上記実施形態の構成によれば、イオンを含む気流の一部は循環路２７、凹部８及び第１吸気路１１を通って集塵部３０に導かれる。これにより、集塵部３０に堆積した塵埃の脱臭や除菌を行うことができ、さらに静電気の発生を抑制することができる。したがって、室内の脱臭効果や除菌効果の向上を図ることができるのとともに、集塵部３０に堆積した塵埃を廃棄するときのユーザーの煩わしさを解消することが可能な掃除ロボット１を提供することができる。 And according to the configuration of the above-described embodiment of the present invention, a part of the air flow including ions is guided to the dust collection unit 30 through the circulation path 27, the recess 8 and the first intake path 11. Thereby, the deodorization and sterilization of the dust accumulated on the dust collection part 30 can be performed, and generation | occurrence | production of static electricity can be suppressed further. Accordingly, it is possible to provide the cleaning robot 1 that can improve the indoor deodorizing effect and the sterilizing effect and can eliminate the troublesomeness of the user when the dust accumulated in the dust collecting unit 30 is discarded. be able to.
　次に、本発明の第３実施形態に係る掃除ロボットについて、図１６を用いて説明する。図１６は掃除ロボットの垂直断面部分側面図である。なお、この実施形態の基本的な構成は前記第１及び第２実施形態と同じであるので、それらの実施形態と共通する構成要素には前と同じ符号を付し、図面の記載及びその説明を省略するものとする。 Next, a cleaning robot according to a third embodiment of the present invention will be described with reference to FIG. FIG. 16 is a vertical sectional partial side view of the cleaning robot. Since the basic configuration of this embodiment is the same as that of the first and second embodiments, the same components as those of the embodiments are denoted by the same reference numerals as before, and the description of the drawings and the description thereof. Shall be omitted.
　第３実施形態の掃除ロボット１は、図１６に示すように循環路２９がその開口面２９ａ及び凹部８の壁面に設けた孔部８ｂを介して凹部８に連通している。そして、循環路２９は回転ブラシ９が配置された箇所より前方に設けられ、吸込口６を通して床面上にイオンを含む気流を吹き付ける向きで凹部８に接続されている。 In the cleaning robot 1 of the third embodiment, as shown in FIG. 16, the circulation path 29 communicates with the recess 8 through the opening surface 29 a and the hole 8 b provided in the wall surface of the recess 8. The circulation path 29 is provided in front of the place where the rotary brush 9 is disposed, and is connected to the recess 8 in such a direction that an air stream containing ions is blown onto the floor surface through the suction port 6.
　このようにして第３実施形態の構成によれば、イオンを含む気流が吸込口６を通して床面上に吹き付けられた後、凹部８及び第１吸気路１１を通って集塵部３０に導かれる。これにより、イオンが集塵部３０に導かれるとともに、床面上にも散布される。その結果、集塵部３０に堆積した塵埃に加えて、床面に対しても脱臭や除菌、静電気の発生を抑制する作用を向上させることが可能になる。 Thus, according to the structure of 3rd Embodiment, after the airflow containing ion is sprayed on the floor surface through the suction inlet 6, it is guide | induced to the dust collection part 30 through the recessed part 8 and the 1st air intake path 11.

As a result, in addition to the dust accumulated in the dust collecting unit 30, it is possible to improve the action of suppressing the generation of deodorization, sterilization, and static electricity on the floor surface.
