JP 2012-217798 A Japanese Patent No. 4512624

When cleaning the suction port unit for cleaning the floor surface of Patent Document 1, the user usually uses a cleaning tool such as a brush or a brush to remove the rotating brush exposed to the outside from the dust collection opening that opens at the bottom of the housing. Clean. Alternatively, the rotary brush can be removed from the lower case part and cleaned by removing the upper case part from the lower case part of the housing and removing the belt of the rotational force transmission mechanism from the pulley integrated with one end of the rotary brush. Is possible. However, since electric parts such as a motor and a circuit board are fixed to the lower case portion, the inside of the lower case portion can be cleaned with a cleaning tool but cannot be washed with water.

For this reason, dust that has been difficult to reach with cleaning tools such as corners in the lower case part, gaps between electrical parts and the lower case part, and fibrous dust such as hair and lint accumulate without being removed. . In addition, mites, germs, and the like that are confused with dust and fibrous dust remaining in the suction port unit easily propagate. Therefore, there is a problem that such an unsanitary suction port unit must be stored and used continuously.

In addition, when cleaning the suction port unit for cleaning the bedding of Patent Document 2, the beater can be removed and cleaned, but since electrical components such as a motor and a circuit board are fixed in the suction port unit, The inside of the inlet unit cannot be washed with water. Therefore, similarly to the floor cleaning suction port unit, the bedding cleaning suction port unit has a problem that the suction port unit in an unsanitary state must be stored and used continuously. In the case of the suction port unit for bedding cleaning, since the bedding that touches the human skin is cleaned, it is particularly desired to solve this problem.

Also, when cleaning the floor and bedding, from the standpoint of hygiene, function, etc., a dedicated suction port unit (floor surface suction port unit or bedding cleaning suction) according to the surface to be cleaned Mouth unit) must be used. For this reason, electrical components such as a motor and a circuit board must be provided in each dedicated suction port unit corresponding to the surface to be cleaned, which raises a problem that the manufacturing cost of the suction port unit increases.

In view of this, the present inventor replaces the mounting unit having the cleaning member for cleaning the floor and the mounting unit having the cleaning member for cleaning the bedding into the suction port body containing the electric parts such as the motor and the circuit board. Thus, it has been found that the manufacturing cost of the inlet unit can be reduced.

In addition, the floor cleaning inlet unit of Patent Literature 1 and the bedding cleaning inlet unit of Patent Literature 2 use a cooling air passage that cools electric components such as a motor and a circuit board by using an air current when the vacuum cleaner is driven. However, the present inventor has found that the electrical component can be cooled by providing a cooling air passage in the suction port body.

[Mounting the floor cleaning mounting unit to the inlet]
FIG. 12A is a diagram illustrating a state where the suction port main body and the mounting unit are separated from each other in the first embodiment, and FIG. 12B is a diagram illustrating a state where the mounting unit is mounted on the suction port main body. FIG. 13 is a partial cross-sectional view showing a state in which the mounting unit according to Embodiment 1 is mounted on the suction port body. FIG. 14A is a cross-sectional view showing a state before the mounting unit mounted on the suction port unit in Embodiment 1 is locked with a lock member, and FIG. 14B is a cross-sectional view showing the state after locking.

When the mounting unit 51 is mounted on the suction port body 52, as shown in FIG. 12A, the suction port body 52 is moved above the mounting recess 51z of the mounting unit 51, and as shown in FIG. to, inserting the first housing portion 52a ₁ of the suction inlet main body 52 to the mounting recess 51z of the mounting unit 51. Then, as shown in FIG. 13, by sliding the suction port body 52 to the right, the drive gear portion 52a ₂ of the suction port body 52 meshes with the gear portion 51b ₂₆ of the rotating brush unit 51b. At this time, the wheels 52a _{32 of the} suckable state detection unit 52a ₃ protrude downward from the window 51a ₁₁₁ of the mounting unit 51.

Further, the plurality of locking projections 51 a ₁₃₁ of the lower case 51 a ₁ are locked to the plurality of locking grooves 52 a ₅ of the suction port body 52. As shown in FIGS. 7 (A) and 7 (B), each locking groove 52a ₅ is formed in an overturned L shape, and each locking projection is fitted in each locking groove 52a _5. 51a ₁₃₁ can slide in the horizontal (left and right) direction after sliding in the vertical (up and down) direction.

In addition, by sliding the suction inlet body 52 laterally with respect to the mounting unit 51 to the limit, a locking sound “click” is generated. As shown in FIG. 13, the locking sound is generated when the mounting portion 51 is mounted by the convex portion 52 a ₁₂ provided so as to protrude and retract outward from the bottom of the first housing portion 52 a ₁ of the suction port body 52. It is emitted by engaging with an engaging recess 51z ₁ provided in the recess 51z. From this locking sound, the user can recognize that the mounting unit 51 has been securely mounted to the suction port body 52.

In this case, for example, the convex portion 52a ₁₂ is formed in a bullet shape having a roundness at the lower end, and is elastically biased downward by a not-shown bullet member. Further, the engagement recess 51z ₁ can be a recess formed on the top of the projection 51z _{2 that} is rounded on the bottom surface of the mounting recess 51z. Thus, it is the convex portion 52a ₁₂ is engaged with the engaging recess 51z ₁ overcame rounded portion of the projections 51z _2, and the engaging sound stop tends emitted during locking.

After the suction port body 52 is slid laterally to the limit with respect to the mounting unit 51 and mounted, the lock member is placed in the space on the left side of the first housing portion 52a ₁ of the suction port body 52 in the mounting recess 51z of the mounting unit 51. 51a ₃ is inserted. Thereby, the mounting unit 51 mounted on the suction port body 52 is fixed.

At this time, as shown in FIGS. 14 (A) and 14 (B), the lock member 51a _{3 with} respect to the lock detection part 52ax provided in the left side portion of the first housing part 52a ₁ of the suction inlet main body 52. For example, when the lock member 51a ₃ turns on the switch part of the lock detection part 52ax, the lock detection part 52ax outputs a lock detection signal. Further, by removing the lock member 51a ₃ , the switch part of the lock detection part 52ax is turned off, and the output of the lock detection signal from the lock detection part 52ax is stopped.

The lock detection signal is input to, for example, a control unit provided in the cleaner body 2, and the control unit controls driving of the motor M based on the lock detection signal. That is, when the mounting unit 51 is properly mounted and fixed to the suction port body 52, a lock detection signal is input to the control unit.

According to the vacuum cleaner 1 having the suction port unit 5 in which the floor cleaning mounting unit 51 is mounted on the suction port body 52, the suction port unit 5 is placed on the floor as described above. wheels 52a ₃₂ of the suction state detecting portion 52a ₃ is suction state detection signal is output up, the suction state detection signal is input to the control unit by.

Therefore, the driving force of this motor is applied to the rotational cleaning member of the mounting unit. The driving force transmission mechanism for transmitting can be arranged on one end side of the rotational cleaning member in the mounting unit.
Thereby, it becomes a structure which can arrange | position a motor storage chamber, an intake hole, and an exhaust hole easily to a suction inlet main body. In addition to this, a large part (driving force transmission mechanism) that obstructs suction is not disposed near the suction port disposed in the middle of the left and right of the suction port body, so that the suction performance of the suction port unit is lowered. There is nothing.

Further, when the driving force transmission mechanism is arranged in the middle of the left and right of the first housing part, the configurations of the driving force transmission mechanism and the rotation cleaning member become complicated, and the first housing part and the second housing part The connecting portion of the inlet becomes larger and the appearance of the suction port body deteriorates. On the other hand, by disposing the driving force transmission mechanism on one end side of the first housing portion, the configuration of the driving force transmission mechanism and the rotational cleaning member can be simplified, and the appearance of the suction port body is improved. There are also benefits.

(II) The motor may have a front end of the output shaft disposed on the intake hole side and a proximal end of the output shaft disposed on the exhaust hole side.
According to this configuration, the motor output shaft and the driving force transmission mechanism are arranged on one end side of the first casing unit, the air intake holes are arranged on one end side of the first casing unit, and the length of the first casing unit is set. It is a rational structure in which an exhaust hole is arranged on the suction port side in the middle direction.

(IV) The suction port may be configured to form a substantially vertical surface with respect to the cleaning surface.
By doing so, the projection area of the ventilation path connected to the opening on the mounting unit connected to the suction port of the first casing is reduced, so that the first casing can be made compact.

Further, according to another aspect of the present invention, the suction port body, and a cleaning mounting unit mounted on the suction port body,
There is provided a suction port unit of a vacuum cleaner, wherein the mounting unit is a floor surface cleaning mounting unit having a rotatable rotating brush or a bedding cleaning mounting unit having a swinging hitting plate.

It should be understood that the disclosed embodiments are illustrative and non-restrictive in every respect. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
