As shown in FIGS. 1 and 2, a conventional vacuum cleaner specifically designed for cleaning blackboards has a motor 1 as an airflow suction device, a filter 2 for filtering dust, and a suction plate 3.
The structure is such that the dust adhering to the blackboard cloth is collected into the filter 2 by air flow from a single slit-shaped suction port 4 provided near the end of the filter.
また、黒板に、黒板ふき掃除機の機能をもたせ
るようにしたものが、実用昭54−119437号公報に
よつて知られている。 Further, a blackboard equipped with the function of a blackboard wiping cleaner is known from Japanese Utility Model No. 119437/1983.
従来の黒板ふき専用の掃除機では、第２図の実
線及び一点鎖線で示す黒板ふき５を矢印の方向に
往復摺動させる必要があり、次のような問題点が
あつた。
In the conventional vacuum cleaner exclusively used for wiping a blackboard, it is necessary to slide the blackboard wiping 5 indicated by the solid line and the dashed-dot line in FIG. 2 back and forth in the direction of the arrow, and the following problems arise.
すなわち、１つのスリツト状吸込口４を吸込板
３の端部近傍に配設してあるために、
(1) 黒板ふき５の移動量Ｌは、黒板ふき５の全長
以上、必要であり、手、腕を動かす労力が大き
い。 That is, since one slit-shaped suction port 4 is disposed near the end of the suction plate 3, (1) the amount of movement L of the blackboard wiper 5 is required to be greater than the entire length of the blackboard wiper 5, and , it takes a lot of effort to move the arm.

外に落下してしまい、黒板ふき用掃除機の設置
場所がきたなくなる。(2) To clean the entire surface of the blackboard wipe 5, it is necessary to move the blackboard wipe to position No. B in Figure 2. Therefore, as shown in FIG.
It will fall outside and make the place where the chalkboard vacuum cleaner is installed messy.
という問題があつた。There was a problem.
さらに、実開昭54−119437号公報に示す黒板で
は、吸込面全面に多数の小孔を設けているため
に、黒板ふきに付着したチヨーク粉の吸込性能が
悪いという問題点があつた。 Furthermore, the blackboard disclosed in Japanese Utility Model Application Publication No. 54-119437 has a problem in that it has poor suction performance for the chalk powder adhering to the blackboard cloth because it has a large number of small holes all over the suction surface.

The above object consists of a main body case that houses a motor and a filter, and a suction plate that also serves as a lid of this main case, and the airflow sucked into the main body case from the suction port provided on this suction plate is passed through the filter. In a chalkboard cleaning vacuum cleaner configured to discharge air from an exhaust port of the main body case, the suction port is disposed in a central portion of the suction body, and the suction port is arranged at a position intersecting with the moving direction of the chalkboard wiper. a plurality of slit-shaped holes extending in the direction of This is achieved by forming ribs on the part.
複数個のスリツト状穴を吸込板の中央部に設け
てあるので、黒板ふき全面を掃除するための、黒
板ふき移動量は小さくてすむ。
Since a plurality of slit-shaped holes are provided in the center of the suction plate, the amount of movement of the blackboard wiper to clean the entire surface of the blackboard wiper can be small.
複数個のスリツト状穴のうち、一部のスリツト
長さを他部のスリツト長さよりも長くすることに

すべてのスリツト状穴を黒板ふきでおおつた状態
として、空気もれによるチヨーク粉吸込性能の低
下を小さくおさえることができる。 By making the slit length of some of the plurality of slit-shaped holes longer than the slit length of the other parts, when using a large blackboard cloth, all of the plurality of slit-shaped holes can be covered with the blackboard cloth. This prevents deterioration of powder suction performance due to air leakage, and when cleaning a small blackboard, leave a small portion at both ends of some slit-shaped holes and clean all other slit-shaped holes. By keeping it in a covered state, the deterioration in the powder suction performance due to air leakage can be suppressed.
黒板ふきの移動量が小さく、しかも吸込板の周
囲にリブがあるので、チヨーク粉が吸込板から黒

に延びる構成になつている。 The suction port 15 has a plurality of slit holes 15a,
15b, and the slit length of some parts is set longer than the slit length of other parts. In this embodiment, as shown by the dotted line in FIG.
The relationship between b and slit length 2 is set as 1 > 2 . A slit-like hole 15a with a long slit length is provided in the center of the suction plate 3, and a plurality of slit-like holes 1 are provided on the left and right sides of the slit-like hole 15a.
5b is arranged. Slit holes 15a, 15b
is configured to extend in a direction intersecting the moving direction of the blackboard wipe 5.

掃除できる。 As shown in Fig. 4, if the blackboard wipe 5 is moved back and forth in the direction of the arrow by a small stroke L', the dust will be removed by squeezing and suction through one of the plurality of slit holes 15a and 15b. Can be completely cleaned.
黒板ふき５は、吸込板３のリブ１４を乗越える
ことはないので、黒板ふき用掃除機本体外に落下
することがない。 Since the blackboard wiper 5 does not go over the ribs 14 of the suction plate 3, it does not fall outside the main body of the cleaner for cleaning the blackboard.

For this purpose, a wide area is sucked through the hole 15a,
The part of the blackboard wipe 5a that corresponds to the hole 15b can be moved back and forth by shifting the blackboard wipe from side to side, and there is no performance deterioration due to air leakage from the suction ports 15a, 15b.

下を極力小さくすることができる。 In addition, as shown in FIG. 6, in the case of a small blackboard wipe 5b, all the suction ports 15 are slit holes
If the hole is long like the one shown in a, airflow will leak and flow in from the hole opened beyond the width of the blackboard wipe 5b, reducing the suction force. In this respect, in this embodiment, only the central slit-shaped hole 15a has a longer slit length, and the other slit-shaped holes 15b are hidden under the blackboard cloth 5b, so that no air leakage occurs. Furthermore, in the case of the small blackboard wipe 5b, the entire surface can be cleaned by simply making a small reciprocating movement over the suction ports 15a and 15b, and the deterioration in performance due to air leakage can be minimized.
