Description

本発明は、人間の介助なしに自立して走行する自走式掃除機およびそのプログラムに関するものである。   The present invention relates to a self-propelled cleaner that travels independently without human assistance and a program thereof.

従来、この種の自走式掃除機として、上部の障害物との距離を検知するための上部距離検知手段と、標準よりも簡易な掃除モードを選択可能な簡易掃除モード選択手段を備え、前記簡易掃除モード選択手段で簡易な掃除モードが選択された時は、前記上部距離検知手段で検知する上部距離が閾値未満の場所は走行しないようにするものがある(例えば、特許文献1参照)。   Conventionally, as this type of self-propelled cleaner, provided with an upper distance detection means for detecting the distance to the obstacle at the upper part, and a simple cleaning mode selection means capable of selecting a simpler cleaning mode than the standard, When the simple cleaning mode is selected by the simple cleaning mode selection means, there is one that prevents traveling where the upper distance detected by the upper distance detection means is less than a threshold (for example, see Patent Document 1).

これは、図5に示すように、自走式掃除機本体1が、走行するための走行手段である駆動輪2、上部の障害物との距離を検知するための上部距離検知手段3、ゴミを吸引するための掃除手段である吸引手段4、駆動輪2の走行速度を可変するための走行速度可変手段5、吸引手段4の吸引能力を可変するための吸引能力可変手段6、走行速度可変手段5と吸引能力可変手段6を介して駆動輪2および吸引手段4の制御を行う制御手段7、標準よりも簡易な掃除モードを選択可能な簡易掃除モード選択手段8を備えている。   As shown in FIG. 5, the self-propelled cleaner main body 1 has a driving wheel 2 which is a traveling means for traveling, an upper distance detecting means 3 for detecting a distance from an upper obstacle, dust, Suction means 4 that is a cleaning means for sucking in, driving speed variable means 5 for varying the traveling speed of the drive wheel 2, suction capacity variable means 6 for varying the suction capacity of the suction means 4, and variable traveling speed A control means 7 for controlling the driving wheel 2 and the suction means 4 via the means 5 and the suction capacity variable means 6 and a simple cleaning mode selection means 8 capable of selecting a cleaning mode simpler than the standard are provided.

そして、図6に示すように、まず、使用者は簡易掃除モード選択手段8で予め掃除を標準モードで行うか、簡易モードで行うか選択しておく(STEP1)。制御手段7は、走行速度可変手段5を介し駆動輪2を制御して走行を開始すると共に、吸引能力可変手段6により予め使用者によって設定された吸引レベルにして吸引手段4を起動する(STEP2)。次に、制御手段7は、上部距離検知手段3で検知した上部距離が1cm未満の時は、障害物回避動作を行う(STEP3、4)。上部距離が1cm以上3cm未満の時は、簡易掃除モード選択手段8で選択されている掃除モードをチェックする(STEP5、6)。簡易掃除モードが選択されている場合には、その進行方向への走行を回避するように制御し、即ち上部距離が3cm以上になるまで回転した後に走行を継続させる(STEP7)。標準掃除モードが選択されている場合には、その進行方向への走行をそのまま継続させる。

Then, as shown in FIG. 6, the user first selects in advance whether the cleaning is performed in the standard mode or the simple mode using the simple cleaning mode selection means 8 (STEP 1). The control means 7 controls the drive wheel 2 via the travel speed varying means 5 to start running, and activates the suction means 4 to the suction level preset by the user by the suction capacity varying means 6 (STEP 2). ). Next, the control means 7 performs an obstacle avoidance operation when the upper distance detected by the upper distance detection means 3 is less than 1 cm (STEPs 3 and 4). When the upper distance is 1 cm or more and less than 3 cm, the cleaning mode selected by the simple cleaning mode selection means 8 is checked (STEPs 5 and 6). When the simple cleaning mode is selected, control is performed so as to avoid traveling in the traveling direction, that is, the traveling is continued after rotating until the upper distance becomes 3 cm or more (STEP 7). When the standard cleaning mode is selected, the traveling in the traveling direction is continued as it is.

しかしながら、前記従来の構成では、複雑な場所であるベッドやテーブルなどの下を間引いた簡易な掃除モードで掃除を行う場合も、一度、ベッドやテーブルなどの物陰に入り回避動作が必要となるため、その回避動作のために掃除時間が長くなり掃除効率が低下するという課題を有していた。   However, in the conventional configuration, even when cleaning is performed in a simple cleaning mode in which the bottom of a bed or table, which is a complicated place, is thinned out, it is necessary to enter into the shadow of the bed or table once to avoid the operation. Because of the avoidance operation, the cleaning time becomes long and the cleaning efficiency is lowered.

本発明は、前記従来の課題を解決するもので、予め各位置毎の上部の障害物との距離を記憶し、記憶する上部距離が閾値以上の位置のみを走行することで、複雑な場所であるベッドやテーブルなどの物陰に入ることなく、短時間で最低限度の掃除を効率的に行うことができる自走式掃除機を提供することを目的とする。   The present invention solves the above-mentioned conventional problems, stores the distance from the upper obstacle for each position in advance, and travels only at a position where the upper distance to be stored is equal to or greater than a threshold, so that the complicated place can be used. It is an object of the present invention to provide a self-propelled vacuum cleaner that can efficiently perform a minimum cleaning in a short time without entering a shadow of a certain bed or table.

前記従来の課題を解決するために、本発明の自走式掃除機は、走行手段と、掃除手段と、走行位置を検出する走行位置検出手段と、各位置毎の上部の障害物との距離情報を含む走行マップを記憶する走行マップ記憶手段と、制御手段を備え、前記制御手段は、前記走行位置検出手段で検出される走行位置をもとに前記走行マップ記憶手段に記憶される上部距離が閾値以上の位置のみ走行するように前記走行手段を制御するものである。   In order to solve the above-described conventional problems, the self-propelled cleaner of the present invention includes a travel means, a cleaning means, a travel position detection means for detecting a travel position, and a distance between an upper obstacle for each position. An upper distance stored in the travel map storage means based on a travel position detected by the travel position detection means; The traveling means is controlled so that the vehicle travels only at a position equal to or greater than a threshold value.

これによって、予め各位置毎の上部の障害物との距離を記憶し、記憶する上部距離が閾値以上の位置のみを走行することで、複雑な場所であるベッドやテーブルなどの物陰に入ることなく、短時間で最低限度の掃除を効率的に行うことができる。   As a result, the distance from the upper obstacle for each position is stored in advance, and only the position where the stored upper distance is equal to or greater than the threshold is used, so that it does not enter a complicated place such as a bed or table. Therefore, the minimum cleaning can be efficiently performed in a short time.

また、本発明のプログラムは、自走式掃除機における機能の少なくとも一部をコンピュータに実行させるものである。   Moreover, the program of this invention makes a computer perform at least one part of the function in a self-propelled cleaner.

これによって、プログラムであるので、電気・情報機器、コンピュータ、サーバーなどのハードリソースを協働させて自走式掃除機の少なくとも一部を容易に実現することができる。また、磁気メディアや光メディアなどの記録媒体に記録したり、インターネットなどの通信回線を用いて配信したりすることで、新しい機能の配布・更新やそのインストール作業が簡単にできる。   Accordingly, since it is a program, at least a part of the self-propelled cleaner can be easily realized by cooperating hardware resources such as an electric / information device, a computer, and a server. In addition, by recording on a recording medium such as magnetic media or optical media, or by using a communication line such as the Internet, distribution / update of new functions and installation work thereof can be easily performed.

By using the self-propelled cleaner to be controlled, the distance from the upper obstacle for each position can be stored in advance, and only the position where the stored upper distance is equal to or greater than the threshold can be traveled. Therefore, it is possible to efficiently perform the minimum cleaning in a short time without entering a shadow of a complicated place such as a bed or a table.

The travel map update means is stored in the travel map storage means when the difference between the upper distance measured by the upper distance measurement means and the upper distance stored in the travel map storage means is greater than or equal to a threshold at a certain travel position. The upper distance information is updated to the upper distance information measured by the upper distance measuring means. Thereby, even if the position of the bed, table, or the like is changed in the traveling area, the stored upper distance information can be updated without taking time and effort for the user.

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

図1に示すように、掃除を行う自走式掃除機本体101は、走行を行うための走行手段である駆動輪102、ゴミを吸引するための掃除手段である吸引手段103、駆動輪2の回転数から走行距離を検出するエンコーダ104、走行方向を検出するジャイロ105、エンコーダ104とジャイロ105で検出された走行距離と走行方向をもとに走行位置を検出する走行位置検出手段106、各位置毎の上部の障害物との距離情報を含む走行マップを記憶する走行マップ記憶手段107、駆動輪102および吸引手段103を制御する制御手段108、閾値などを設定する設定手段109を有する。   As shown in FIG. 1, a self-propelled cleaner body 101 that performs cleaning includes a driving wheel 102 that is a traveling means for traveling, a suction means 103 that is a cleaning means for sucking dust, and a driving wheel 2. An encoder 104 that detects a travel distance from the number of revolutions, a gyro 105 that detects a travel direction, a travel position detection means 106 that detects a travel position based on the travel distance and travel direction detected by the encoder 104 and the gyro 105, and each position A travel map storage unit 107 that stores a travel map that includes distance information with respect to obstacles at the top of each unit, a control unit 108 that controls the drive wheels 102 and the suction unit 103, and a setting unit 109 that sets a threshold and the like.

そして、前記制御手段108は、走行位置検出手段106で検出される走行位置をもとに走行マップ記憶手段107に記憶される上部距離が閾値以上の位置のみ走行するように駆動輪102を制御するものである。   The control means 108 controls the drive wheels 102 so that the upper distance stored in the travel map storage means 107 travels only at a position equal to or greater than a threshold based on the travel position detected by the travel position detection means 106. Is.

以上のように構成された自走式掃除機について、以下その動作、作用を、図1、図2を用いて説明する。   The operation and action of the self-propelled cleaner configured as described above will be described below with reference to FIGS.

まず、使用者は走行領域におけるベッドやテーブルなどの高さに応じて設定手段109で自走式掃除機本体101が掃除を行って欲しい上部の障害物との距離を設定する(STEP101)。   First, the user sets the distance from the upper obstacle that the self-propelled cleaner main body 101 wants to clean with the setting means 109 according to the height of the bed, table, etc. in the travel area (STEP 101).

設定手段109による設定が終了すると、制御手段108は駆動輪102を駆動させ、吸引手段103を起動し、掃除を開始する(STEP102)。   When the setting by the setting unit 109 is completed, the control unit 108 drives the driving wheel 102, activates the suction unit 103, and starts cleaning (STEP 102).

走行中は、走行位置検出手段106で走行位置を検出する(STEP103)。次に、制御手段108は、走行マップ記憶手段107から走行位置検出手段106で検出された走行位置の次の位置における上部距離が設定手段109で設定された閾値以上かどうかチェックする(STEP104)。設定された閾値以上の場合は、そのまま進行方向へ走行を継続し、設定された閾値未満のときは任意の方向へ方向転換した後、走行を継続する(STEP105)。   During traveling, the traveling position is detected by the traveling position detecting means 106 (STEP 103). Next, the control means 108 checks whether or not the upper distance at the position next to the travel position detected by the travel position detection means 106 from the travel map storage means 107 is greater than or equal to the threshold set by the setting means 109 (STEP 104). If it is equal to or greater than the set threshold value, the vehicle continues to travel in the traveling direction, and if it is less than the set threshold value, the vehicle continues to travel after changing direction in any direction (STEP 105).

以上のように、本実施の形態においては、制御手段108は走行位置検出手段106で検出される走行位置をもとに走行マップ記憶手段107に記憶される上部距離が閾値以上の位置のみ走行するように駆動輪102を制御することで、複雑な場所であるベッドやテーブルなどの物陰に入ることなく、短時間で最低限度の掃除を効率的に行うことができる。   As described above, in the present embodiment, the control unit 108 travels only at a position where the upper distance stored in the travel map storage unit 107 is equal to or greater than the threshold based on the travel position detected by the travel position detection unit 106. By controlling the drive wheels 102 in this manner, the minimum level of cleaning can be efficiently performed in a short time without entering a shadow of a complicated place such as a bed or a table.

また、本実施の形態においては、制御手段108は走行位置検出手段106で検出される走行位置をもとに走行マップ記憶手段107に記憶される上部距離が設定手段109で設定された閾値以上の位置のみ走行するように駆動輪102を制御することで、走行領域におけるベッドやテーブルなどの高さに応じて走行することができる。   Further, in the present embodiment, the control means 108 is such that the upper distance stored in the travel map storage means 107 based on the travel position detected by the travel position detection means 106 is greater than or equal to the threshold set by the setting means 109. By controlling the drive wheel 102 so as to travel only in the position, it is possible to travel according to the height of the bed or table in the travel region.

(実施の形態2)
図3、図4は、本発明の実施の形態2における自走式掃除機を示すものである。
(Embodiment 2)
3 and 4 show a self-propelled cleaner in Embodiment 2 of the present invention.

ここで、本実施の形態では、図1に示した実施の形態1の構成に加えて、上部の障害物との距離を測定する上部距離測定手段110と、走行マップ記憶手段107の各位置の上部距離情報を更新する走行マップ更新手段111と、標準掃除モードまたは標準よりも簡易な簡易掃除モードを選択する掃除モード選択手段112と、掃除モード選択手段112で簡易な掃除モードが連続選択された回数をカウントする簡易掃除モード連続選択カウント手段113と、報知手段114を備える。   Here, in this embodiment, in addition to the configuration of the first embodiment shown in FIG. 1, the upper distance measuring means 110 that measures the distance to the upper obstacle, and the position of each position of the travel map storage means 107. The driving map update means 111 for updating the upper distance information, the cleaning mode selection means 112 for selecting the standard cleaning mode or the simple cleaning mode simpler than the standard, and the simple cleaning mode are continuously selected by the cleaning mode selection means 112. Simple cleaning mode continuous selection counting means 113 for counting the number of times, and notification means 114 are provided.

以上のように構成された自走式掃除機について、以下その動作、作用を、図3、図4を用いて説明する。   The operation and action of the self-propelled cleaner configured as described above will be described below with reference to FIGS.

まず、使用者は予め掃除モード選択手段112で掃除モードを標準掃除モードで行うか、簡易掃除モードで行うか選択する(STEP201)。ここで、簡易掃除モード連続選択カウント手段113は、使用者により簡易掃除モードが選択された場合はカウント数を1UPし、標準掃除モードが選択された場合はカウント数をクリアする(STEP203、204)。制御手段108は、簡易掃除モード連続選択カウント手段113のカウント数が1UPすることでカウント数が5以上となった場合、報知手段114で『簡易掃除モードが続いています』と音声案内することで(その他、文字案内、光案内、あるいは組み合わせ案内などもよい)、長い間、標準掃除モードによるベッドやテーブルなどの物陰の掃除が行われていないことを使用者に知らせる(STEP205、206)。   First, the user selects, in advance, the cleaning mode selection means 112 to perform the cleaning mode in the standard cleaning mode or the simple cleaning mode (STEP 201). Here, the simple cleaning mode continuous selection counting means 113 increments the count number when the simple cleaning mode is selected by the user, and clears the count number when the standard cleaning mode is selected (STEPs 203 and 204). . When the count number of the simple cleaning mode continuous selection counting means 113 is increased by 1 by 5 or more by the control means 108, the notifying means 114 provides voice guidance to the user that “the simple cleaning mode is continuing”. (In addition, text guidance, light guidance, or combination guidance may also be used), the user is informed that the shadow of the bed or table in the standard cleaning mode has not been cleaned for a long time (STEP 205, 206).

報知手段114による音声案内終了後、または簡易掃除モード連続選択カウント手段113のカウント数が5未満の場合、または掃除モード選択手段112で標準掃除モードが選択された場合、制御手段108は駆動輪102を駆動させると共に吸引手段103を起動させ、掃除を開始する(STEP207)。   After the voice guidance by the notification unit 114 is completed, or when the count number of the simple cleaning mode continuous selection counting unit 113 is less than 5, or when the standard cleaning mode is selected by the cleaning mode selection unit 112, the control unit 108 is driven by the drive wheel 102. And the suction means 103 are activated to start cleaning (STEP 207).

走行中は、上部距離測定手段110で上部の障害物との距離を測定、また、走行位置検出手段106で走行位置を検出する(STEP208、209)。   During traveling, the distance to the upper obstacle is measured by the upper distance measuring means 110, and the traveling position is detected by the traveling position detecting means 106 (STEP 208, 209).

走行マップ更新手段111は走行位置検出手段106で検出された走行位置において、走行マップ記憶手段107に記憶された上部距離と上部距離測定手段110で測定された上部距離の絶対差が5cm以上のとき、走行マップ記憶手段107に記憶されたその位置における上部距離情報を上部距離測定手段110で測定された上部距離情報に更新する(STEP210、211)。   The travel map update means 111 is the travel position detected by the travel position detection means 106 when the absolute difference between the upper distance stored in the travel map storage means 107 and the upper distance measured by the upper distance measurement means 110 is 5 cm or more. Then, the upper distance information at the position stored in the travel map storage means 107 is updated to the upper distance information measured by the upper distance measurement means 110 (STEPs 210 and 211).

制御手段108は、掃除モード選択手段112による掃除モードのチェックを行い、掃除モード選択手段112で標準掃除モードが選択されている場合は、そのまま進行方向へ走行を継続する(STEP212)。掃除モード選択手段112で簡易掃除モードが選択されている場合は、走行マップ記憶手段107に記憶されている次の位置の上部距離情報が3cm以上かどうかチェックし、3cm以上のときはそのまま進行方向へ走行を継続し、3cm未満ときは駆動輪102を制御することで任意の方向へ方向転換し、走行を継続する。   The control means 108 checks the cleaning mode by the cleaning mode selection means 112. If the standard cleaning mode is selected by the cleaning mode selection means 112, the control means 108 continues traveling in the traveling direction (STEP 212). When the simple cleaning mode is selected by the cleaning mode selection means 112, it is checked whether the upper distance information of the next position stored in the travel map storage means 107 is 3 cm or more. If the distance is less than 3 cm, the direction is changed to an arbitrary direction by controlling the driving wheel 102 and the traveling is continued.

本実施の形態において、走行マップ更新手段111はある走行位置において上部距離測定手段110で測定される上部距離と走行マップ記憶手段107に記憶される上部距離の差が閾値以上のとき、走行マップ記憶手段107に記憶される上部距離情報を上部距離測定手段110で測定された上部距離に更新することで、走行領域においてベッドやテーブルなどの位置が変更になっても使用者に手間をかけることなく記憶している上部距離情報を更新することができる。   In the present embodiment, the travel map update unit 111 stores the travel map when the difference between the upper distance measured by the upper distance measurement unit 110 and the upper distance stored in the travel map storage unit 107 is greater than or equal to a threshold at a certain travel position. By updating the upper distance information stored in the means 107 to the upper distance measured by the upper distance measuring means 110, it is possible to save the user time even if the position of the bed or table is changed in the traveling area. The stored upper distance information can be updated.

また、本実施の形態において、制御手段108は簡易掃除モード連続選択カウント手段113のカウント回数が閾値以上になったとき報知手段114で報知することで、使用者は長い間ベッドやテーブルなどの物陰の掃除を行っていないことを知ることができる。   Further, in the present embodiment, the control means 108 notifies the notification means 114 when the count number of the simple cleaning mode continuous selection count means 113 exceeds the threshold value, so that the user can stay in an object such as a bed or table for a long time. You can know that you are not cleaning.
