In addition, on the bottom surface 13 of the main body 11, there are four first level difference sensors 24a and a second level difference sensor 24a, which are collectively referred to as level difference sensors 24, which are arranged near the ends on both sides of the front and rear parts. Detector 24b, third level difference sensor 24c, and fourth level difference sensor 24d. The level difference sensor 24 detects the level difference of the floor surface. When the level difference sensor 24 has detected the level difference of the floor surface, the control circuit 62 (refer to FIG. 9 ) controls the self-propelled vacuum cleaner 10 to retreat in a direction away from the level difference, so as to avoid the level difference. walk.

The left and right pair of driving wheels 17a and 17b are arranged so that the rear protrudes outward when viewed from the upper surface 12 of the main body 11 in the shape of an inverted triangle. Therefore, the bottom surface 13 of the main body 11 is formed in a home plate shape with rounded corners. In addition, in the above, although the structure which arrange|positioned the main brush 15a in the suction opening 19 was demonstrated as an example, it is not limited to this. For example, a configuration in which the main brush is not provided in the suction port 19 may also be employed.

Next, the structure of the front surface side of the main body 11 of the self-propelled (vacuum) cleaner 10 is demonstrated, referring FIG. 4. FIG. FIG. 4 is a front view of the self-propelled cleaner 10 .

As shown in FIG. 4 , the main body 11 is provided with a first ultrasonic sensor 23 a and a second ultrasonic sensor 23 b which are collectively referred to as ultrasonic sensors 23 . The ultrasonic sensor 23 detects obstacles such as walls and the like that exist in front of the self-propelled vacuum cleaner 10 . In addition, the ultrasonic sensor 23 can also reliably detect obstacles formed by materials such as infrared-transmissible glass. Therefore, the self-propelled (vacuum) cleaner 10 can be driven while avoiding contact with an obstacle more reliably.

Specifically, in FIG. 4 , the self-propelled vacuum cleaner 10 of the present embodiment emits ultrasonic waves from the second ultrasonic sensor 23b on the right side toward the front.

Next, the structure of the side surface side of the main body 11 of the self-propelled (vacuum) cleaner 10 is demonstrated, referring FIG.4 and FIG.5. FIG. 5 is a right side view of the self-propelled cleaner 10 .

As shown in FIG. 4 , the main body 11 has at least an infrared sensor 22 a provided on the left side of the front side. The infrared sensor 22a measures the distance to surrounding obstacles. More specifically, the infrared sensor 22a includes a light emitting element emitting infrared rays, a light receiving element receiving infrared rays reflected by obstacles, and the like. In addition, the self-propelled vacuum cleaner 10 of this embodiment cleans the corners of a room, etc., so that the front left side (see FIG. 4 ) of the main body 11 where the brushes 15 are disposed is close to the corners. Therefore, the infrared sensor 22a must be disposed on the front left side of the main body 11 shown in FIG. 4 as an infrared sensor for measuring the distance to obstacles. That is, it is preferable that the infrared sensor 22a is disposed only on the front left side of the main body 11 shown in FIG. 4 . Thereby, cost reduction of the self-propelled (vacuum) cleaner 10 can be aimed at. However, as shown in FIG. 4 and FIG. 5 , an infrared sensor 22 a and an infrared sensor 22 b may be respectively provided on the front left side and the front right side of the main body 11 . Thereby, it is possible to more reliably detect obstacles and the like around the main body 11 .

Next, the configuration around the housing portion 30 of the main body 11 of the self-propelled (vacuum) cleaner 10 will be described with reference to FIGS. 6 and 7 .

The third opening 32 is connected to a suction port (not shown) of a suction motor 61 (see FIG. 9 ) through a flow path 66 of an air suction duct portion 60 described later using FIG. 26 .

Moreover, as shown in FIG. 7, the dust collecting box 40 is provided with the filter 44 etc. which can open and close with respect to the accommodating part 43, the cover body 41, and the accommodating part 43. The accommodating portion 43 accommodates dust and the like sucked from the suction port 19 . The cover body 41 is disposed so as to cover the upper side of the housing portion 43 , and constitutes a part of the upper surface 12 of the main body 11 in a state of being housed in the housing portion 30 of the main body 11 . The filter 44 functions to prevent the dust accommodated in the accommodating portion 43 from passing through, and also to pass air. Thus, dust and the like are accommodated in the accommodation portion 43 .

Moreover, the upper part of the filter 44 is locked on the upper surface 12 of the main body 11 and closed by the opening and closing mechanism 45 provided on the upper part of the accommodating part 43 . On the other hand, when the user wants to discard the dust accommodated in the accommodating portion 43, first, the button 47 (refer to FIG. 13C ) provided on the upper surface of the accommodating portion 43 described later is pressed. Thereby, the filter 44 which can be opened and closed with respect to the accommodating part 43 is comprised so that the engagement with the accommodating part 43 by the opening and closing mechanism 45 can be disengaged and opened.

As mentioned above, the cover body 41 has a notch portion 42 , and the aforementioned notch portion 42 is used for the user to hook fingers when opening the cover body 41 . On the other hand, the accommodating part 30 is equipped with the recessed part 33 which is formed in the upper surface 12 of the main body 11, and has the depth of the grade which a user's finger can enter. The concave portion 33 is formed at a position facing the notch portion 42 of the cover body 41 when the dust box 40 is stored in the storage portion 30 . Thereby, the user can easily open the cover 41 by putting the finger into the concave portion 33 and hooking the finger into the notch 42 of the cover 41 . The opening surface of the first opening 31 of the accommodating part 30 is inclined so as to face obliquely upward. Here, the opening surface inclined to face obliquely upward refers to a state in which the upper end portion on the upper side of the first opening 31 is inclined toward the front side with respect to the lower end portion on the lower side of the first opening 31 .

In addition, the reason for inclining the first opening 31 will be described later.

Next, the schematic structure of the chassis 20 built in the main body 11 of the self-propelled (vacuum) cleaner 10 is demonstrated, referring FIG. 8. FIG. FIG. 8 is a perspective view of the chassis 20 of the self-propelled cleaner 10 .

As shown in FIG. 8, the chassis 20 has the storage part 30 formed in the front part side, and accommodates the dust box 40. As shown in FIG. Furthermore, the chassis 20 has an air intake duct portion 60 disposed on the rear side. The suction duct portion 60 forms a flow path 66 (refer to FIG. 26 ), and the aforementioned flow path 66 is sucked from the suction port 19 by the suction force of the suction motor 61 (refer to FIG. 9 ), and passes through the dust box 40. The air flow path of the filter 44 .

In addition, details of the air intake duct portion 60 will be described later.

Next, the internal structure of the main body 11 of the self-propelled (vacuum) cleaner 10 is demonstrated, referring FIG. 9. FIG. FIG. 9 is a front central longitudinal sectional view of the self-propelled vacuum cleaner 10 in a state where the dust collecting box 40 is housed in the main body 11 .

As shown in FIG. 9 , the front and rear surfaces of the accommodating portion 43 of the dust box 40 are inclined to face obliquely downward. That is, when the accommodating part 43 of the dust collecting box 40 is accommodated in the accommodating part 30, the width|variety of the front-back direction becomes narrow toward the lower part. Thereby, the dust box 40 can be easily attached to and detached from the accommodating portion 30 . As a result, user convenience is improved. Here, "inclined to face obliquely downward" refers to a state in which the upper end portion on the upper side is inclined toward the front side with respect to the lower end portion on the lower side of the front face on the front face of the accommodating portion 43 . On the other hand, it refers to a state in which the upper end portion on the upper side is inclined toward the rear side with respect to the lower end portion on the lower side of the rear face on the rear surface of the housing portion 43 .

Also, as described above, the main body 11 includes the suction motor 61 , the control circuit 62 , the battery unit 63 , and the like, which are arranged inside on the rear side. The suction motor 61 generates suction for attracting dust. The control circuit 62 controls the respective components of the suction motor 61 and the self-propelled (vacuum) cleaner 10 . The battery unit 63 is a component that supplies electric power to the suction motor 61, the control circuit 62, and the like.

Next, the internal structure of the main body 11 of the self-propelled (vacuum) cleaner 10 is demonstrated further, referring FIG. 10. FIG. Fig. 10 is a front central longitudinal sectional view of the main body 11 and the dust collecting box 40 in a state where the dust collecting box 40 of the self-propelled vacuum cleaner 10 has been removed from the main body 11 and separated.

As shown in FIG. 10, the 1st opening 31 of the storage part 30 of the main body 11 is inclined so that it may face obliquely upward as mentioned above, and is formed. The opening surface of the second opening 46 of the dust collecting box 40 connected to the first opening 31 is inclined so as to face obliquely downward. Here, the opening surface is inclined to face obliquely downward means that the upper end portion on the upper side is inclined to the front side with respect to the lower end portion on the lower side of the second opening 46 . Thus, when the dust box 40 is stored in the storage portion 30 , the second opening 46 of the dust box 40 is stored so as to be pressed against the first opening 31 of the storage portion 30 by the self-weight of the dust box 40 . Therefore, the airtightness between the first opening 31 and the second opening 46 is improved.

Similarly, the third opening 32 of the storage portion 30 is formed by inclining so as to face obliquely upward. The filter 44 of the dust box 40 connected to the 3rd opening 32 is installed incline so that it may face obliquely downward. Here, "inclining to face obliquely downward" refers to a state in which the upper end portion of the filter 44 is inclined toward the rear side with respect to the lower end portion of the filter 44 on the lower side. Thereby, when the dust box 40 is stored in the storage part 30 , the opening of the filter 44 of the dust box 40 is stored so as to be pressed against the third opening 32 of the storage part 30 by the self-weight of the dust box 40 . Therefore, the airtightness between the opening of the filter 44 and the third opening 32 is improved.

That is, when the self-propelled vacuum cleaner 10 is used, the dust box 40 must be frequently attached and detached. With the above configuration, the user can easily and maintain a high airtightness while collecting dust. The cartridge 40 is attached to and detached from the storage unit 30 . As a result, self-propelled (vacuum) cleaner 10 having high suction performance can be realized.

In addition, the width G is preferably within a range of 90 mm to 110 mm, and more preferably within a range of 98.0 mm to 98.2 mm. The width H is preferably in the range of 100 mm to 120 mm, more preferably in the range of 112.0 mm to 112.3 mm.

Next, the dimensional relationship in the up-down direction of the main body 11 of the self-propelled (vacuum) cleaner 10 will be specifically described with reference to FIG. 12 . FIG. 12 is an enlarged view of main parts showing an example of the dimensional relationship of the right front portion of the main body 11 of the self-propelled (vacuum) cleaner 10. As shown in FIG.

As shown in Figure 12, the overall height of the self-propelled vacuum cleaner 10, that is, the height I (capital I) from the ground surface K of the driving wheel 17a and the driving wheel 17b to the upper end of the infrared sensor 21 is 92mm. The height J from the floor surface N to the bottom surface 13 is 20 mm.

In addition, the height I (capital I) is preferably in the range of 80 mm to 100 mm, and more preferably 92 mm. The height J is desirably in the range of 10 mm to 30 mm, more preferably in the range of 20.0 mm to 20.5 mm.

In addition, the numerical values described with reference to FIG. 11 and FIG. 12 are merely examples, and it is also possible to design by changing the numerical values. For example, it can also be designed by multiplying the numerical values of the above-mentioned parts by a certain predetermined coefficient (for example, 0.5~2). Thereby, the degree of freedom in the design of the self-propelled vacuum cleaner 10 is improved. In particular, if it is possible to downsize a motor or a circuit board housed in the main body, it is also possible to use the number of the above-mentioned one example. Value multiplied by the value below 1.0 to design. Thereby, a smaller self-propelled vacuum cleaner 10 can be realized.

[Constitution of dust box]

Hereinafter, the structure of the dust box 40 which is the container of the self-propelled (vacuum) cleaner 10 is demonstrated, referring FIGS. 13A to 13D. FIG. 13A is a top view of a state in which the lid body 41 of the dust collecting box 40 is closed (corresponding to a state when it is stored in the storage portion 30 of the main body 11 ). Fig. 13B is a side view of the state where the lid 41 of the dust collecting box 40 is closed. FIG. 13C is a top view of a state in which the lid body 41 of the dust collecting box 40 is opened (corresponding to a state when it is removed from the storage portion 30 of the main body 11 ). FIG. 13D is a side view of the state where the cover 41 of the dust collecting box 40 is opened.

As shown in Fig. 13B and Fig. 13D, the cover body 41 is pivotally supported so as to be able to rotate around the rotating shaft, that is, the shaft 50, which is arranged on the accommodating part 43 for accommodating the sucked dust. Surface 43a. After the user hooks the notch 42 of the cover 41 with a finger and pulls up the cover 41 , the cover 41 rotates upward around the shaft 50 to open the upper surface 43 a of the accommodating portion 43 .

After the cover body 41 is rotated, as shown in FIG. 13C , the button 47 provided on the upper surface 43 a of the accommodating portion 43 appears. The button 47 functions as a button for opening the filter 44 which is an opening and closing part when the dust accommodated in the accommodating part 43 is to be discarded. Therefore, the button 47 is arranged to be operable only when the dust box 40 is detached from the main body 11 . That is, when the dust box 40 is being accommodated in the main body 11 , the button 47 is covered and hidden by the cover 41 . Thereby, it is possible to prevent the user from erroneously operating the button 47 when other than dust is to be discarded. In addition, the appearance of the self-propelled vacuum cleaner 10 is improved.

Next, the opening and closing operation of the filter 44 of the dust box 40 will be described with reference to FIGS. 14A and 14B . Fig. 14A is a side view showing a state in the middle of opening the filter 44 from the state of the dust box 40 shown in Fig. 13D. Fig. 14B is a side view showing a state in which the filter 44 is further opened and fully opened from the state of the dust box 40 shown in Fig. 14A.

As shown in FIG. 14A, in the state where the cover 41 of the dust box 40 has been opened (equivalent to FIG. 13C) Next, when the user presses the button 47 that appears, the engagement between the upper part of the filter 44 and the upper part of the accommodating part 43 performed by the opening and closing mechanism 45 shown in FIG. 7 is disengaged. At this time, the filter 44 is pivotally supported by the accommodating part 43 through the shaft 51 which is a rotation shaft at the lower end side. Therefore, when the accommodating portion 43 and the filter 44 are disengaged, as shown in FIG. 14B , the filter 44 is rotated downward with the axis 51 as the center by the self-weight of the filter 44, so that the accommodating portion The opening 48 of 43 is open. Thereby, as long as the button 47 is pressed, the filter 44 can be opened to discard the dust accommodated in the accommodating portion 43 . Therefore, the user's convenience is improved.

Also, as shown in FIGS. 14A and 14B , the dust collecting box 40 of this embodiment is configured to limit the range of the rotation angle α of the cover body 41 relative to the upper surface 43a of the accommodating portion 43 to an acute angle. That is, even if the cover body 41 is opened to the widest position, the rotation angle α of the cover body 41 relative to the upper surface 43 a of the accommodating portion 43 is still limited to not exceed a right angle.

In addition, as described above, the second opening 46 of the accommodating portion 43 is formed so as to face obliquely downward. Therefore, after the dust collecting box 40 is removed from the main body 11 in its stored posture, the dust accommodated in the accommodating portion 43 may fall out from the second opening 46 facing obliquely downward.

However, in the dust collecting box 40 of the present embodiment, the cover body 41 and the accommodating portion 43 are formed integrally through the shaft 50 . In addition, the dust collecting box 40 is configured so that the rotation angle α of the cover body 41 with respect to the upper surface 43 a of the accommodating portion 43 does not exceed a right angle. Therefore, when holding the cover body 41 of the dust collecting box 40 to remove the dust collecting box 40 from the main body 11 and carry it, as long as the user holds the cover body 41 in a nearly vertical direction, the accommodating portion 43 can The second opening 46 faces slightly obliquely upward. Thereby, it is possible to reduce the dust contained in the accommodating portion 43 from falling out from the second opening 46 .

Moreover, when the user holds the cover body 41 and presses down the button 47 with the upper surface 43 a of the accommodating portion 43 opened, the filter 44 is opened. At this time, the dust collecting box 40 will be in a state where the opening 48 of the accommodating part 43 faces slightly obliquely downward. Thereby, the dust accommodated in the accommodating portion 43 becomes easier to fall to the outside from the opening 48 . Therefore, the user's convenience and operability are improved.

In addition, a more desirable configuration is that the cover body 41 is placed so that the rotation angle α of the cover body 41 with respect to the upper surface 43a of the accommodating portion 43 is smaller than the angle at which the cover body 41 is parallel to the opening surface of the second opening 46 . The body 41 is pivotally supported so as to be rotatable relative to the upper surface 43 a of the accommodating portion 43 . Thereby, the dust falling out from the second opening 46 of the accommodating part 43 can be further reduced.

Hereinafter, the structure of the cover body 41 of the dust collecting box 40 is demonstrated, referring FIGS. 15-17. FIG. 15 is a perspective view of a state where the cover 41 of the dust collecting box 40 has been opened. FIG. 16 is a perspective view of dust box 40 viewed from below. FIG. 17 is an enlarged view of a part of the central vertical cross-sectional view of the front view of the self-propelled (vacuum) cleaner 10 .

First, as shown in FIG. 15 , the cover body 41 has a rib 52 , and the rib 52 is provided on the back surface (the surface facing the upper surface 43 a of the accommodating portion 43 ), especially on the back side of the periphery of the notch 42 . , and used to reinforce the cover 41 . Thereby, the deformation|transformation of the cover body 41 etc. can be reduced. Moreover, when the dust collecting box 40 is removed from the main body 11 , the user can hook the fingers to the rib 52 through the notch 42 , thereby making it easier to hold the cover 41 . Therefore, the user's convenience and workability are further improved.

In addition, as shown in FIG. 15 , the ribs 52 are formed not only at the portion where the user hooks his fingers, but also at plural positions on the back surface of the cover body 41 .

In addition, the cover body 41 has a pair of left and right first locking portions 49 a and second locking portions 49 b formed on the back surface and extending downward. The first locking portion 49a and the second locking portion 49b are locked to the locked portion 34b provided on the main body 11 when the dust box 40 is stored in the storage portion 30 of the main body 11 (see FIG. 19 ). Thereby, the cover body 41 and the accommodating portion 43 constituting the dust collecting box 40 are fixed in the accommodating portion 30 of the main body 11 . In this case, the first locking portion 49 a and the second locking portion 49 b may be collectively referred to as the locking portion 49 .

In addition, the details of the locking portion 49 will be described later.

Moreover, as shown in FIG. 16 , the area of the cover body 41 of the dust collecting box 40 is larger than the area of the upper surface 43 a of the accommodating portion 43 . Therefore, when the user wants to discard the dust contained in the accommodating portion 43 of the dust collecting box 40 to a trash can, etc., the back of the cover 41 that does not overlap with the accommodating portion 43 can be abutted against the upper part of the trash can. The edge of the opening is fixed. Thereby, since it becomes easier to discard the dust accommodated in the accommodating portion 43, the User convenience is improved. In addition, dust raised when discarded from the accommodating portion 43 into a trash can can be blocked by the lid 41 against which the opening of the trash can abuts. Therefore, scattering of dust can be suppressed. In addition, among the back of the cover body 41, a rib 52 is formed at a portion for the user to abut against the edge of the upper opening of the trash can. Thereby, even if the lid body 41 is abutted against the trash can, a firm structure in which the lid body 41 is hardly deformed can be realized.

Furthermore, as shown in FIG. 17 , the cover body 41 has a rib 52 provided on the back side of the peripheral portion of the above-mentioned notch 42 . The rib 52 is formed at a position where the user can hook the finger to pull up the cover 41 , that is, at a position receding from the end 42 a of the notch 42 toward the accommodating portion 43 . Thereby, the user can easily open the cover 41 by putting fingers into the concave portion 33 of the main body 11 and pulling up the peripheral portion of the notch 42 with the fingers. Therefore, the user's convenience and operability are improved. Moreover, the rib 52 is a part of the gap between the recessed part 33 and the cover body 41 which closes. Thereby, the aesthetics of the appearance of the self-propelled vacuum cleaner 10 is improved.

Here, another configuration example of the self-propelled (vacuum) cleaner 10 will be described with reference to FIG. 18 . FIG. 18 is a perspective view showing another configuration example of the self-propelled (vacuum) cleaner 10 .

As described above, according to the technique of this embodiment, the dust box 40 is housed in the front side of the main body 11 , and a part of the front part of the upper surface 12 is constituted by the cover body 41 of the dust box 40 . That is, the appearance of the upper surface 12 of the main body 11 is divided into a front part and a rear part. Therefore, a configuration may be adopted in which external devices 27 such as sensors, lamps, and drive recorders are mounted on the rear side of the upper surface 12 where the cover body 41 is not provided.

In addition, although a sensor is mentioned as an example of the external device 27, a LIDAR (Light Detection And Ranging or Laser Imaging Detection And Ranging) etc. which are used to measure the distance to an obstacle or the position of an obstacle, etc. can be exemplified.

Next, the locking part 49 of the cover body 41 of the dust collecting box 40 will be further described with reference to FIGS. 19 to 21 .

In addition, in Fig. 19 to Fig. 21, although it is in the locking part 49, the second locking part 49b is described as an example, but since the first locking portion 49a is also the same, description thereof will be omitted.

Fig. 19 is a cross-sectional view of main parts around the second locking portion 49b in a state where the lid body 41 of the dust collecting box 40 is closed. FIG. 20 is a cross-sectional view around the second locking portion 49b when the cover 41 of the dust box 40 is opened. FIG. 21 is a cross-sectional view around the second locking portion 49b when the second locking portion 49b of the cover 41 of the dust box 40 is detached from the locked portion 34b.

First, as shown in FIG. 19, when the dust box 40 has been stored in the storage portion 30 of the main body 11 and the cover 41 is closed, a pair of left and right first locking parts 49a (refer to 15 ) and the second locking portion 49b are engaged from the front side (front side) to a pair of left and right locked portions (not shown) provided on the main body 11 and the lower end of the locked portion 34b. Thereby, the dust box 40 is fixed on the main body 11 .

At this time, the tip of the protrusion 53b provided on the rear side of the shaft 50 on the rear surface of the cover 41 presses down the elastic part 35b provided on the main body 11 . Therefore, the protruding portion 53b of the cover body 41 is given upward potential energy by the elastic portion 35b. That is, the rear part of the cover body 41 from the shaft 50 is given upward potential energy. Thereby, with the shaft 50 as a fulcrum, the rotational force in the direction of closing the lid body 41 is applied to the lid body 41 . Therefore, the airtightness inside the main body 11 caused by the cover body 41 can be further improved, and the suction performance can be improved.

Moreover, the 2nd locking part 49b is formed with material, such as a flexible thermoplastic resin, such as ABS resin, for example. Therefore, as shown in FIG. 20 , when the user rotates the cover body 41 upward, the second locking portion 49 b of the dust box 40 moves forward (front side) while bending. Thereby, the engagement between the second locking portion 49b and the locked portion 34b of the main body 11 is disengaged. At this time, the locked portion 34b has an inclined surface 34ba inclined to face obliquely upward near the upper portion. Therefore, the stress applied to the second locking portion 49b due to the contact with the locked portion 34b can be reduced. Thereby, occurrence of troubles such as breakage of the second locking portion 49b can be prevented in advance.

In addition, as shown in FIG. 21 , when the engagement between the second locking portion 49b of the dust box 40 and the locked portion 34b of the main body 11 is disengaged, the elastic portion 35b returns to its natural length. Therefore, the cover body 41 and the accommodating portion 43 can be integrally pushed upward by the restoring force of the elastic portion 35b. In this way, the dust can be easily The cartridge 40 is removed from the main body 11 . As a result, the user's convenience and workability are further improved.

[Structure of layer difference sensor]

Hereinafter, the step sensor 24 arranged on the bottom surface 13 side of the main body 11 of the self-propelled cleaner 10 will be described with reference to FIGS. 22 and 23 . FIG. 22 is a bottom view of the self-propelled cleaner 10 . FIG. 23 is a cross-sectional view of main parts around the level difference sensor 24 .

In addition, FIG. 22 is a diagram showing the first level difference sensor 24a, the second level difference sensor 24b, the third level difference sensor 24c, and the fourth level difference sensor 24, which will be collectively referred to as the level difference sensor 24.

(Second protrusion 14b). Thereby, the second level difference sensor 24b is configured to be able to simultaneously use the function of detecting the level difference of the ground plane such as the front and left floor surfaces. Therefore, the number of level difference sensors can be reduced, and the manufacturing cost of the self-propelled vacuum cleaner 10 can be reduced.

That is, in the self-propelled (vacuum) cleaner 10 of this embodiment, the brush 15 is provided in the 1st protrusion part 14a, and the 2nd level difference sensor 24b is provided in the vicinity of the 2nd protrusion part 14b. Thereby, cleaning performance can be improved, maintaining safety|security with respect to falling of the self-propelled (vacuum) cleaner 10, etc., for example.

In addition, the first level difference sensor 24a is located behind the vicinity of the first protruding portion 14a, and the light-emitting element 25 and the light-receiving element 26 are arranged side by side in the left-right direction of the main body 11 . Therefore, the dimension (full length A (refer FIG. 11)) of the main body 11 in the front-back direction can be reduced. Thereby, the self-propelled cleaner 10 can be miniaturized.

Next, the operation of the level difference sensor 24 will be described using FIG. 23 . As described above, the level difference sensor 24 includes: a light emitting element 25 that emits light such as laser light, and a light receiving element 26 that detects light reflected by a floor surface or the like.

Specifically, as shown in FIG. 23 , the light emitting element 25 irradiates light toward the floor surface directly below. The light receiving element 26 receives light incident from an oblique direction after being reflected by a floor surface or the like. Thereby, compared with the case where the light receiving element 26 is arranged parallel to the floor surface, the light reflected by the floor surface can be received more efficiently, and the detection accuracy can be improved. In addition, with the configuration of the second level difference sensor 24b, it is possible to quickly detect the level difference further ahead. Therefore, the safety of the self-propelled vacuum cleaner 10 can be further improved.

Moreover, as shown in FIG. 26, the self-propelled (vacuum) cleaner 10 of this embodiment is arrange|positioned at the position where the suction direction of the suction motor 61 is orthogonal to the dust box 40. As shown in FIG. Therefore, in the air intake duct portion 60 , as shown by a blank arrow in the figure, an L-shaped flow path 66 bent at right angles is formed, for example. Thereby, the main body 11 can be miniaturized.

In addition, the suction motor 61 is not limited to the above arrangement position, and may be arranged at any position according to the shape and size of the main body 11 . For example, it may be arranged at a position where the suction direction of the suction motor 61 faces the dust box 40 . In this case, a linear flow path is formed in the intake duct portion 60 . Thereby, the width|variety of the front-back direction of the self-propelled (vacuum) cleaner 10 can be narrowed.
