Detailed Implementation

[0035] In one or more embodiments, the floor scrubber may also include: a base comprising a brush that contacts the surface of the object being cleaned; a main body disposed above the base and including a handle; a supply box for containing cleaning fluid supplied to the surface of the object being cleaned; and a recovery box for containing recovered fluid collected from the surface of the object being cleaned. The supply box may also be disposed in the main body. The recovery box may also be disposed in the base.

[0036] Based on the above configuration, with the supply box located in the main body and the recycling box located in the base, the floor scrubber exhibits good weight balance. Consequently, the floor scrubber demonstrates excellent operability.

[0037] Furthermore, since the supply box is located in the main body, the cleaning fluid contained in the supply box drips onto the surface of the object being cleaned due to its own weight. Therefore, it is unnecessary to use, for example, a pump to supply the cleaning fluid to the surface of the object being cleaned.

[0038] In addition, since the recycling box is located at the base, even if the main body is tilted relative to the base by the operator, the overflow of the recycling liquid contained in the recycling box will be suppressed.

[0039] Furthermore, as the cleaning operation progresses, the amount of cleaning fluid contained in the supply box gradually decreases. In other words, as the cleaning operation progresses, the weight of the supply box becomes lighter. Since the supply box is located in the main body, the lighter weight of the supply box gradually reduces the burden on the operator who supports the handle of the main body as the cleaning operation progresses.

[0040] Furthermore, as the cleaning operation progresses, the amount of recycled liquid collected in the recycling bin increases. In other words, the weight of the recycling bin increases as the cleaning operation progresses. Since the recycling bin is located at the base, the increased burden on the operator supporting the handle of the main body is mitigated even though the weight of the recycling bin increases.

[0041] In one or more embodiments, the floor scrubber may also have a power supply. The power supply may also be located in the main body.

[0042] Based on the above configuration, since the power supply is located in the main body, contact between the power supply and the cleaning fluid supplied to the surface of the object being cleaned is suppressed. Furthermore, since the power supply is positioned higher than the recovery container, even if the recovery fluid overflows from the recovery container, contact between the power supply and the recovery fluid is also suppressed.

[0043] In one or more embodiments, the floor scrubber may also include a suction motor that is driven to recover the recycled liquid from the surface of the object being cleaned. The suction motor may also be disposed at the base.

[0044] Based on the above configuration, since the suction motor and the recovery box are respectively located at the base, there is no need for the suction motor to draw the recovery liquid to a high position. Therefore, the power consumption of the suction motor is suppressed. Furthermore, since the suction motor and the recovery box are positioned at almost the same height, even if the recovery liquid contained in the recovery box overflows onto the surface of the object being cleaned, contact between the suction motor and the recovery liquid is suppressed.

[0045] In one or more embodiments, the positions of the supply box and the recycling box may be different, and the positions of the supply box and the suction motor may also be different.

[0046] Based on the above configuration, the floor scrubber exhibits good weight balance.

[0047] In one or more embodiments, the position of the supply box and the position of the recycling box may be different, and the position of at least a portion of the recycling box may be the same as the position of the suction motor.

[0048] Based on the above configuration, the floor scrubber exhibits good weight balance. Furthermore, by configuring the recycling bin to cover the suction motor, the propagation of noise generated by the suction motor to the surrounding area of ​​the floor scrubber is suppressed.

[0049] In one or more embodiments, the positions of the supply box and the recycling box may be different, and the positions of the power supply and the suction motor may also be different.

[0050] Based on the above configuration, the floor scrubber exhibits good weight balance.

[0051] In one or more embodiments, the power supply may be arranged in the middle of the main body in the left-right direction, in the front of the main body in the front-back direction, or in the lower part of the main body in the up-down direction.

[0052] Based on the above configuration, the floor scrubber exhibits good weight balance.

[0053] In one or more embodiments, the supply box may be arranged in the middle of the main body in the left-right direction, in the middle of the main body in the front-back direction, or in the lower part of the main body in the up-down direction.

[0054] Based on the above configuration, the floor scrubber exhibits good weight balance.

[0055] In one or more embodiments, the recycling box may be arranged on the left, middle and right sides of the base in the left-right direction, on the middle and rear sides of the base in the front-back direction, and on the base in the up-down direction.

[0056] Based on the above configuration, the floor scrubber exhibits good weight balance.

[0057] In one or more embodiments, the suction motor may be arranged in the middle of the base in the left-right direction, in the middle of the base in the front-back direction, or in the base in the up-down direction.

[0058] Based on the above configuration, the floor scrubber exhibits good weight balance.

[0059] In one or more embodiments, two power supplies may also be provided.

[0060] Based on the above configuration, the operating time of the floor scrubber becomes longer.

[0061] In one or more embodiments, the two power supplies can also be configured in the vertical or horizontal direction.

[0062] Based on the above configuration, the floor scrubber exhibits good weight balance.

[0063] The embodiments of the present invention will now be described with reference to the accompanying drawings, but the present invention is not limited thereto. The constituent elements of the embodiments described below can be appropriately combined. In addition, sometimes some constituent elements are not used.

[0064] In the implementation, the terms front, back, left, right, up, and down are used to describe the positional relationships of the various parts. These terms indicate the relative position or direction with the center of the floor scrubber as a reference.

[0066] The left end of the "left part" corresponds to the left end of the floor scrubber. The right end of the "right part" corresponds to the right end of the floor scrubber. In the left-right direction, the dimensions of the "left part," the "middle part," and the "right part" are equal. That is, the floor scrubber is divided into three equal parts in the left-right direction, thus defining the "left part," "middle part," and "right part." The space between the left and right ends of the floor scrubber is also divided into three equal parts in the left-right direction, thus defining the "left part," "middle part," and "right part."

[0067] The front end of the "front section" is the same as the front end of the floor scrubber. The rear end of the "rear section" is the same as the rear end of the floor scrubber. In the front-to-back direction, the dimensions of the "front section," "middle section," and "rear section" are equal. That is, the floor scrubber is divided into three equal parts in the front-to-back direction, thus defining the "front section," "middle section," and "rear section." The space between the front and rear ends of the floor scrubber is also divided into three equal parts in the front-to-back direction, thus defining the "front section," "middle section," and "rear section."

[0068] The upper part of the "upper part" corresponds to the upper part of the floor scrubber. The lower part of the "lower part" corresponds to the lower part of the floor scrubber. The dimensions of the "upper part," "middle part," and "lower part" are equal in the vertical direction. That is, the floor scrubber is divided into three equal parts in the vertical direction, thus defining the "upper part," "middle part," and "lower part." The space between the upper and lower parts of the floor scrubber is also divided into three equal parts in the vertical direction, thus defining the "upper part," "middle part," and "lower part."

Through the rotary joint mechanism 12, the upper and middle parts of the guide section 5 can be tilted relative to the lower part of the guide section 5. That is, the main body 2 can also be tilted relative to the base 3. The main body 2 can also be operated by the operator to tilt relative to the base 3.

[0080] The floor scrubber 1A includes: a feed box 8, a recycling box 9, a power supply 10, and a suction motor 11.

[0081] The supply box 8 contains the cleaning fluid supplied to the surface of the object to be cleaned.

That is, in the left-right direction, the suction motor 11 is disposed in the middle of the floor scrubber 1A. In the left-right direction, the left end and the right end of the suction motor 11 are respectively disposed in the middle of the floor scrubber 1A. In addition, as Figure 1 As shown, the left end of the suction motor 11 can be disposed on the left side of the floor scrubber 1A, and the right end of the suction motor 11 can also be disposed on the right side of the floor scrubber 1A. In the front-to-back direction, the suction motor 11 is disposed in the middle of the floor scrubber 1A. In the front-to-back direction, the front and rear ends of the suction motor 11 are respectively disposed in the middle of the floor scrubber 1A. Furthermore, as... Figure 2 As shown, the front end of the suction motor 11 can be disposed at the front of the floor scrubber 1A, and the rear end of the suction motor 11 can also be disposed at the rear of the floor scrubber 1A. In the vertical direction, the suction motor 11 is disposed at the lower part of the floor scrubber 1A. In the vertical direction, the upper end and the lower end of the suction motor 11 are respectively disposed at the lower part of the floor scrubber 1A.

[0094] As described above, the space between the left and right ends of the floor scrubber 1A is divided into three equal parts in the left-right direction, thereby defining the left, middle, and right parts of the floor scrubber 1A in the left-right direction. The space between the front and rear ends of the floor scrubber 1A is divided into three equal parts in the front-back direction, thereby defining the front, middle, and rear parts of the floor scrubber 1A in the front-back direction. The space between the upper and lower ends of the floor scrubber 1A is divided into three equal parts in the vertical direction, thereby defining the upper, middle, and lower parts of the floor scrubber 1A in the vertical direction.

[0095] In this embodiment, the left end of the floor scrubber 1A is either the left end of the brush 6 or the left end of the collection box 9. The right end of the floor scrubber 1A is either the right end of the brush 6 or the right end of the collection box 9. The front end of the floor scrubber 1A is the front end of the power supply 10. The rear end of the floor scrubber 1A is the rear end of the collection box 9. The upper end of the floor scrubber 1A is the upper end of the handle 4. The lower end of the floor scrubber 1A is the lower end of the brush 6. Additionally, in... Figure 1 as well as Figure 2 In order to make it easier to observe the attached figure, the grid-like dotted lines representing the various parts of the floor scrubber 1A are shown to be slightly separated from the left end, right end, upper end, lower end, front end, and rear end of the floor scrubber 1A.

[0096] As described above, in this embodiment, the floor scrubber 1A includes: a base 3 comprising a brush 6 that contacts the surface of the object being cleaned; a main body 2 disposed above the base 3 and including a handle 4; a supply box 8 for containing cleaning fluid supplied to the surface of the object being cleaned; and a recovery box 9 for containing recovery fluid recovered from the surface of the object being cleaned. The supply box 8 is disposed on the main body 2. The recovery box 9 is disposed on the base 3.

[0097] Based on the above configuration, since the supply box 8 is located in the main body 2 and the recycling box 9 is located in the base 3, the floor scrubber 1A has good weight balance. As a result, the floor scrubber 1A has good operability.

[0098] Furthermore, since the supply box 8 is located in the main body 2, the cleaning fluid contained in the supply box 8 drips onto the surface of the object being cleaned due to its own weight. Therefore, it is not necessary to have, for example, a pump for supplying the cleaning fluid to the surface of the object being cleaned.

[0099] In addition, since the recycling box 9 is located on the base 3, even if the main body 2 is tilted relative to the base 3 by the operator, the overflow of the recycling liquid (dirt liquid) contained in the recycling box 9 will be suppressed.

[0100] Furthermore, as the cleaning operation progresses, the amount of cleaning fluid contained in the supply box 8 gradually decreases. That is, as the cleaning operation progresses, the weight of the supply box 8 becomes lighter. Since the supply box 8 is located in the main body 2, the lighter weight of the supply box 8 gradually reduces the burden on the operator who supports the handle 4 of the main body 2 as the cleaning operation progresses.

[0101] Furthermore, as the cleaning operation progresses, the amount of recycled liquid contained in the recycling box 9 increases. That is, as the cleaning operation progresses, the weight of the recycling box 9 increases. Since the recycling box 9 is located in the base 3, the increased burden on the operator supporting the handle 4 of the main body 2 is mitigated even though the weight of the recycling box 9 increases.

[0102] In this embodiment, the floor scrubber 1A includes a power supply 10. The power supply 10 is located in the main body 2.

[0103] Based on the above configuration, since the power supply 10 is located in the main body 2, contact between the power supply 10 and the cleaning fluid supplied to the surface of the object being cleaned is suppressed. Furthermore, since the power supply 10 is positioned higher than the recycling bin 9, even if the recycling fluid overflows from the recycling bin 9, contact between the power supply 10 and the recycling fluid is suppressed.

[0104] In this embodiment, the floor scrubber 1A includes a suction motor 11 that is driven to recover the recycled liquid from the surface of the object being cleaned. The suction motor 11 is disposed on the base 3.

[0105] Based on the above configuration, since the suction motor 11 and the recovery box 9 are respectively disposed at the base 3, it is not necessary for the suction motor 11 to draw the recovery liquid to a high position. As a result, the power consumption of the suction motor 11 is suppressed. In addition, since the suction motor 11 and the recovery box 9 are disposed at almost the same height, even if the recovery liquid contained in the recovery box 9 overflows onto the surface of the object being cleaned, contact between the suction motor 11 and the recovery liquid is suppressed.

[0106] In this embodiment, the position of the supply box 8 is different from the position of the recycling box 9, and the position of the supply box 8 is different from the position of the suction motor 11.

[0107] Based on the above configuration, the floor scrubber 1A exhibits good weight balance.

[0108] In this embodiment, the position of the supply box 8 is different from the position of the recycling box 9, and at least a portion of the recycling box 9 is in the same position as the suction motor 11.

[0109] Based on the above configuration, the floor scrubber 1A exhibits good weight balance. Furthermore, by configuring the recycling bin 9 to cover the suction motor 11, the propagation of noise generated by the suction motor 11 to the vicinity of the floor scrubber 1A is suppressed.

[0110] In this embodiment, the position of the supply box 8 is different from that of the recycling box 9, and the position of the power supply 10 is different from that of the suction motor 11.

[0111] Based on the above configuration, the floor scrubber 1A exhibits good weight balance.

[0112] In this embodiment, the power supply 10 is disposed in the middle of the main body 2 in the left-right direction, in the front of the main body 2 in the front-back direction, and in the lower part of the main body 2 in the up-down direction.

[0113] Based on the above configuration, the floor scrubber 1A exhibits good weight balance.

[0114] In this embodiment, the supply box 8 is disposed in the middle of the main body 2 in the left-right direction, in the middle of the main body 2 in the front-back direction, and in the lower part of the main body 2 in the up-down direction.

[0115] Based on the above configuration, the floor scrubber 1A exhibits good weight balance.

[0116] In this embodiment, the recycling box 9 is arranged on the left, middle and right sides of the base 3 in the left-right direction, on the middle and rear sides of the base 3 in the front-back direction, and on the base 3 in the up-down direction.

[0117] Based on the above configuration, the floor scrubber 1A exhibits good weight balance.

[0118] In this embodiment, the suction motor 11 is disposed in the middle of the base 3 in the left-right direction, in the middle of the base 3 in the front-back direction, and in the base 3 in the up-down direction.

[0119] Based on the above configuration, the floor scrubber 1A exhibits good weight balance.

[0120] [Second Implementation]

[0121] The second embodiment will be described below. In the following description, the same reference numerals will be used for the same or equivalent components as those in the above embodiment, and the description of these components will be simplified or omitted.
