Moreover, the 1st exhaust passage 24a is formed in the direction extended along the discharge direction A5a (refer FIG. 7) from one exhaust port of the motor casing 22a of the turbofan which is the electric blower 22. Regarding the discharge direction A5a of the turbofan, that is, the air flow direction, as shown in FIG. the

On the other hand, the first exhaust passage 24b is formed in a direction different from the discharge direction A5b from the other exhaust port of the motor housing 22a. The first exhaust passage 24b extends upward with respect to the discharge direction A5b directed downward. the

Although not shown in FIGS. 4 to 8 , as shown in FIG. 9 , a second filter 50 and a sound insulating material 51 are provided in the second exhaust passage 24 b. The second filter 50 is constituted by 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 includes glass wool, urethane resin, etc., and is attached to the inner surface or the outer surface of the second exhaust passage 24b. the

Moreover, as shown in FIG. 10, the 1st valve 26 is provided in the 1st exhaust path 24a and the 2nd exhaust path 24b, respectively. The first valve 26 operates according to a control signal received from the control board 14 . 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 24 b not containing ions can be adjusted by using the first valve 26 . the

According to setting, cleaning robot 1 can operate the first valve 26 with the state that the electric blower 22 is driving to adjust the flow rate and the flow rate of the airflow of the first exhaust passage 24a containing ions after the cleaning operation is completed or during charging of the battery 13.

When the cleaning robot 1 comprised as mentioned above is instructed to perform a cleaning operation, 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 rotating brush 9 , the driving wheel 5 and the rear wheel 16 of the main body housing 2 contact the floor F to automatically move within a predetermined range, and the airflow containing dust from the floor F is sucked in from the suction port 6 . At this time, by the rotation of the rotating brush 9 , the dust on the floor surface F is rolled up and introduced into the concave portion 8 . In addition, dust on the sides of the suction port 6 is introduced into the suction port 6 by the rotation of the side brush 10 . the

The airflow inhaled from the suction port 6 flows backward in the first air suction path 11 as shown by arrow A1, and flows into the dust collecting part 30 through the inlet 34a. The airflow which flowed into the dust collecting part 30 is captured and collected by the 1st filter 33, and flows out from the dust collecting part 30 through the outlet 35a.

The airflow flowing through the first exhaust passage 24a includes the ions released by the ion generator 25, and flows toward the exhaust port 7 as indicated by arrow A3a. The airflow flowing through the second exhaust path 24b does not contain ions, is collected by the second filter 50, is silenced by the soundproof material 51, and flows toward the exhaust port 7 as indicated by arrow A3b. the

Then, an airflow containing ions is exhausted obliquely upward and rearward from the exhaust port 7 provided on the upper surface of the main body housing 2 as indicated by arrow A3. In this way, the room is cleaned, and the ions contained in the exhaust gas of the self-propelled main body casing 2 spread throughout the room to perform room sterilization and deodorization. At this time, since the air is exhausted upward from the exhaust port 7, it is possible to prevent the dust on the floor F from being rolled up and to improve the cleanliness of the room. the

In addition, when both wheels of the driving wheels 5 are rotated in opposite directions, the main body housing 2 is rotated around the center line C to change its direction. Thereby, the main body housing 2 can be made to run automatically over the entire desired range and to avoid obstacles. In addition, the main body case 2 may be moved backward by reversing both wheels of the driving wheels 5 relative to the forward direction. the

When the cleaning is finished, the main body box 2 automatically returns to the charging stand 40 . Thus, the charging terminal 4 is connected to the terminal portion 41, and the battery 13 is charged. According to the settings, the cleaning robot 1 can operate the ion generator 25 and the first valve 26 in a state where the electric blower 22 is being driven to adjust the first exhaust passage 24a containing ions after the cleaning operation is completed or while the battery 13 is being charged.

As mentioned above, the cleaning robot 1 is equipped with the exhaust flow path formed by the first exhaust passage 24a and the second exhaust passage 24b between the electric blower 22 and the exhaust port 7, so the back pressure of the electric blower 22 can be reduced. Lower to improve suction performance. In addition, the cleaning robot 1 is equipped with an ion generator 25 that discharges ions to the first exhaust passage 24a that is one path of the exhaust flow passage. Therefore, the airflow that has passed through the electric blower 22 releases ions from the first exhaust passage 24a and from the first exhaust passage 24a. Exhaust port 7 sends out to indoor. Therefore, the flow velocity on the exhaust side can be increased to facilitate sending ions into the chamber. the

Also, when forming a plurality of exhaust flow paths, each of the plurality of exhaust paths has a smaller cross-sectional area than when there is one exhaust path. As a result, the flow velocity of the exhaust gas can be further increased. Furthermore, by providing the ion generator so that ions can be released from one of the exhaust paths, the ions can be scattered farther. the

In addition, the cleaning robot 1 is provided with a second filter 50 in the second exhaust path 24b that does not release ions among the multiple paths of the exhaust flow path, so that the airflow that does not contain ions passes through the second filter 50 from the exhaust port. 7 discharge. Therefore, the cleaning of the exhaust gas of the cleaning robot 1 can be improved without causing the ions to disappear due to the filter. the

In addition, the cleaning robot 1 is provided with a soundproof material 51 in the second exhaust path 24b that does not release ions among the plurality of paths of the exhaust flow path. Outlet 7. Thereby, ions are not lost due to the sound insulating material, and it is possible to improve the quietness of the exhaust gas of the cleaning robot 1 . the

In addition, the cleaning robot 1 is equipped with a first valve 26 capable of adjusting the flow rate of the airflow of the first exhaust passage 24a containing ions and the second exhaust passage 24a containing no ions among the plurality of paths of the exhaust flow passage.
