Next, a supporting state of cover 20 will be described with reference to fig. 7 to 11.

The support mechanism 30 can support the cover portion 20 in a plurality of support states with respect to the main body portion 10. In the present embodiment, the plurality of support states includes a first support state J1, a second support state J2, a third support state J3, and a fourth support state J4. The position of the cover portion 20 with respect to the main body portion 10 in the up-down direction differs for each support state.

The vertical direction is an example of the axial direction of the present invention.

Fig. 7 is a view showing cover portion 20 in first support state J1. Fig. 8 is a diagram illustrating an operation of attaching cover 20 to main body 10.

The first support state J1 represents a state of the cover portion 20 at a stage in which the cover portion 20 is mounted to the body portion 10.

As shown in fig. 7, when the cover portion 20 is supported by the support mechanism 30 in the first support state J1, the convex portion 32 is placed on the main body protrusion 33.

When the convex portion 32 of the cover portion 20 is placed on the body protrusion 33 of the body portion 10, the position of the guide groove 35 is the same as the position of the cover protrusion 34 in the vertical direction. As a result, the cover protrusion 34 can be guided to the guide groove 35 by rotating the cover portion 20 in the axial direction P.

When cover portion 20 is supported in first support state J1, cover portion 20 is separated upward from the ground by the height of body protrusion 33, and therefore, a gap X is formed between peripheral portion 27 of cover portion 20 and the ground. The dimension X1 in the upward direction of the gap X is, for example, 20mm to 40 mm.

The procedure of bringing cover 20 into first support state J1 will be described with reference to fig. 7 and 8. Fig. 8 is a diagram illustrating an operation of inserting the body 10 into the cover 20.

As shown in fig. 8, the user inserts the first portion 11 into the cover 20 through the second opening 22, and then lowers the cover 20 relative to the body 10. As shown in fig. 7, when the cover 20 is lowered relative to the body 10, the convex portion 32 is placed on the body protrusion 33. As a result, the state of the cover 20 becomes the first support state J1.

When the cover 20 is in the first support state J1, a gap X is formed between the peripheral portion 27 of the cover 20 and the floor surface. As a result, the user's fingers can be prevented from being pinched by the peripheral portion 27 of the cover portion 20.

Fig. 9 is a diagram showing the cover portion 20 in the second support state J2.

The second support state J2 represents a state in which the cover portion 20 is mounted on the main body portion 10. In a state where the cover portion 20 is supported with respect to the main body portion 10 in the second support state J2, the user uses the air cleaner 100.

As shown in fig. 9, when the cover portion 20 is supported by the support mechanism 30 in the second support state J2, the main body protrusion 33 is inserted from below into the recess 31, and the main body protrusion 33 engages with the recess 31 from below. When the cover portion 20 is supported by the support mechanism 30 in the second support state J2, the cover protrusion 34 enters from above the first engagement portion 36, and the cover protrusion 34 engages with the first engagement portion 36 from above.

Fig. 10 is a diagram showing the cover portion 20 in the third support state J3.

The third support state J3 represents a state of the cover portion 20 when only the cover portion 20 of the main body portion 10 and the cover portion 20 is lifted.

As shown in fig. 10, when the cover portion 20 is supported by the support mechanism 30 in the third support state J3, the cover protrusion 34 enters from below the second engagement portion 37, and the cover protrusion 34 engages with the second engagement portion 37 from below. As a result, the cover 20 is restricted from moving upward relative to the main body 10.

A change in the state of cover 20 will be described with reference to fig. 9 and 10.

As shown in fig. 9 and 10, when the user carries air cleaner 100 from a state in which cover portion 20 is supported in second support state J2, and pulls up only cover portion 20 by gripping only cover portion 20 out of main body portion 10 and cover portion 20 without gripping grip portion 3, the state of cover portion 20 is changed to third support state J3. As a result, since the cover 20 is locked to the main body 10, the cover 20 can be prevented from falling off from the main body 10 even if the user merely holds the cover 20 and transports the air purifier 100.

Fig. 11 is a diagram showing the cover portion 20 in the fourth support state J4.

The fourth supporting state J4 represents a state of the hood portion 20 when maintenance of the air cleaner 100 is performed.

As shown in fig. 11, when the cover portion 20 is supported by the support mechanism 30 in the fourth support state J4, the cover protrusion 34 is placed on the cover protrusion 34 with respect to the third engagement portion 38, and the cover protrusion 34 engages with the third engagement portion 38 from above. As a result, the cover 20 is restricted from moving downward with respect to the main body 10. Further, the peripheral portion 27 is kept in a state separated upward from the main body protrusion 33 by the engagement of the cover protrusion 34 with the third engaging portion 38.

When cover portion 20 is supported in fourth supported state J4, peripheral portion 27 is located above through-hole 131, and through-hole 131 is exposed without being covered by cover portion 20. As a result, the user can perform maintenance of the air cleaner 100 by replacing the filter C attached to the through hole 131 or removing dust adhering to the filter C. In addition, since the maintenance of the air cleaner 100 can be performed without detaching the cover 20 from the main body 10, the maintenance of the air cleaner 100 can be easily performed.

As shown in fig. 7 to 11, at the position in the vertical direction with respect to the main body portion 10, the cover portion 20 in the first supported state J1, the cover portion 20 in the second supported state J2, the cover portion 20 in the third supported state J3, and the cover portion 20 in the fourth supported state J4 are located upward in the order of the cover portion 20 in the second supported state J2, the cover portion 20 in the first supported state J1, the cover portion 20 in the third supported state J3, and the cover portion 20 in the fourth supported state J4.

A mechanism by which the state of cover 20 is switched to any one of the first supported state J1 to the fourth supported state J4 will be described with reference to fig. 7 to 11.

As shown in fig. 7 and 9, when cover 20 is rotated in the axial direction P from the state where cover 20 is supported in the first support state J1, the state of cover 20 is switched to the second support state J2. Specifically, the cover portion 20 rotates to the other side P2 in the axial direction P, so that the cover protrusion 34 enters the guide groove 35 and then drops toward the first engagement portion 36. As a result, the state of the cover 20 is switched from the first support state J1 to the second support state J2.

As shown in fig. 9 and 10, when cover 20 is moved upward from the state in which cover 20 is supported in second support state J2, the state of cover 20 is switched to third support state J3. Specifically, when the cover portion 20 moves upward, the cover protrusion 34 moves from the first engagement portion 36 to the second engagement portion 37 via the guide groove 35. As a result, the state of the cover portion 20 is switched to the third support state J3.

As shown in fig. 8 and 11, when the cover portion 20 is attached to the main body portion 10 in a state where the position of the cover protrusion portion 34 is the same as the position of the third engaging portion 38 in the position in the axial direction P, the cover protrusion portion 34 is placed on the third engaging portion 38. As a result, the cover 20 is supported in the fourth support state J4.

As shown in fig. 7, 9, 10, and 11, when cover 20 is in any one of first support state J1, second support state J2, and third support state J3, cover 20 is appropriately rotated about axis P and moved in the vertical direction, and the state of cover 20 is switched to fourth support state J4.

As shown in fig. 7 and 11, in a state where cover portion 20 is supported in fourth support state J4, cover portion 20 rotates in axial direction P at the position in axial direction P, and then cover portion 20 moves downward to a position where the position of cover protrusion 34 is different from the position of third engagement portion 38, so that the state of cover portion 20 is switched to first support state J1. In this case, when the cover portion 20 rotates in the axial direction P, the cover protrusion 34 can be smoothly separated from the third engaging portion 38 by the curved portion 38c (see fig. 6) of the third engaging portion 38.

As shown in fig. 7, the cover 20 is moved upward in a state where the position of the cover protrusion 34 is different from all the positions of the guide groove 35, the first engagement portion 36, the second engagement portion 37, and the third engagement portion 38 in the axial direction P, and the cover 20 is detached from the main body 10. The cover 20 is detached from the body 10, meaning that the body 10 is located outside the cover 20 and is separated from the cover 20.

As described above with reference to fig. 7 to 11, the support mechanism 30 can switch the state of the cover portion 20 to any one of a plurality of support states (from the first support state J1 to the fourth support state J4). In addition, the position of the cover portion 20 with respect to the main body portion 10 in the up-down direction differs for each supported state. Therefore, the position of the cover portion 20 with respect to the main body portion 10 is changed in the vertical direction by switching the state of the cover portion 20 to any one of the first supported state J1 to the fourth supported state J4. As a result, the position of the cover 20 with respect to the body 10 can be switched without detaching the cover 20 from the body 10.

Further, by performing at least one of the operation of rotating the cover 20 in the axial direction P with respect to the main body 10 and the operation of moving the cover 20 in the vertical direction with respect to the main body 10, the support mechanism 30 switches the state of the cover 20 to any one of the plurality of support states (the first support state J1 to the fourth support state J4) without detaching the cover 20 from the main body 10. Therefore, the user can easily perform the task of switching the state of cover 20.
