Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary electric shaver capable of being washed.

[0002]

2. Description of the Related Art There is a rotary electric shaver of a type in which a portion provided with an outer blade and an inner blade can be washed in order to remove whiskers accumulated in a space inside a main body case.

Conventionally, there is a rotary electric shaver capable of cleaning as shown in FIG. 1 in FIG.
Is a main body case, and a motor 3 is housed in the head portion 2 formed in the main body case 1. An opening 4 is formed on a peripheral side portion surrounding the open portion of the head portion 2, and the opening 4 is opened and closed by a ring 5 rotatably provided on the peripheral side portion. Reference numeral 6 denotes an outer cutter base to which an outer cutter 7 is attached, which is fitted to the head portion 2. Reference numeral 8 denotes an inner blade base to which an inner blade 9 is attached, which is attached to the output shaft of the motor 3.

In this structure, at the time of cleaning, the head portion 2 is immersed in water and the inner blade base 8 is rotated by the motor 3 to agitate the water so that it is formed between the head portion 2 of the main body case 1 and the outer blade 7. The whiskers present in the whiskers holding space a are made to flow out through the opening 4 of the head portion 2 together with water.

By the way, in this electric razor,
In order to remove the whiskers more reliably, Fig. 5
It is considered that foam cleaning with a detergent is performed using the cap 11 shown in FIG. The cap 11 covers the outer blade 7 and the outer blade base 6 from the outside, and a hole 12 for air intake and detergent injection is formed in the central portion. Cap 11
An opening 13 is formed on the peripheral side of the
Is opened and closed by a ring 14 rotatably provided on the circumferential side.

At the time of cleaning, the cap 11 is fitted into the head portion 2 and the head portion 2 is immersed in water W. Then, when the detergent is put into the inside of the cap 11 through the hole 12 of the cap 11 and the inner blade 9 is rotated, the water and the detergent enter the whisker-holding space a and the inside of the cap 11 through the opening 4 of the head portion 2. Flows alternately with the space b. Further, by the rotation of the inner blade 9, air is sucked into the cap 11 from the hole 12 and the water, the detergent and the air are stirred to generate bubbles.

Bubbles grow with the passage of time, and when the bubbles grow sufficiently, they flow inside the cap 11 and convect between the spaces a and b. For this reason, the frictional force between the bubbles and the surface of the head portion 2 and the surface of the inner blade 9 becomes strong, the whiskers adhering to these surfaces are peeled off, the cleaning effect is enhanced, and whiskers and the like are removed. The removed whiskers and the like are discharged from the opening 13 of the cap 11 to the outside.

[0008]

However, in the conventional foam cleaning, a part of the foam is removed by the cap 1 while the foam is growing.
Escape to the outside of the cap 11 through the hole 12 of 1.
As a result, the escape of bubbles to the outside of the cap 11 hinders the growth of bubbles inside the cap 11 and delays the time until the bubbles grow sufficiently. Therefore, it takes a long time for the foam generation and growth processes and a long cleaning time until the foam grown inside the cap convection reaches a state where a sufficient cleaning effect can be obtained. There's a problem.

The present invention has been made in view of the above circumstances, and shortens the time from the stage of foam generation to the stage where the foam grows and a sufficient cleaning effect due to flow is obtained, thereby shortening the foam. An object of the present invention is to provide a rotary electric razor with a reduced cleaning time.

[0010]

The rotary electric shaver of the present invention has been made to achieve the above-mentioned object, and is composed of a main body case, an outer blade provided in the main body case, and a position inside the outer blade. With an inner blade to do, with a whisker storage space between the main body case and the inner blade,
In an electric shaver in which an opening communicating with the beard accumulating space and the outside of the main body case is formed in the main body case, a portion where the outer blade and the opening portion of the main body case are present is outside the space portion. A cap for cleaning bubbles, which is provided at a portion facing the inner blade of the cap, which is provided with holes for air intake and excess foam circulation for communicating the inside and the outside with the peripheral side of the cap. The part is formed with an opening for taking in air and discharging excess bubbles, which communicates the inside and the outside of the part, and the hole and the opening are connected via a connection passage.

[0011]

Function When the bubble is washed, the cap is put on the main body case, and the aqueous detergent solution is injected into the inside of the cap through the opening on the peripheral side of the cap. Then, the inner blade is rotated to agitate the air and the detergent solution to generate bubbles inside the cap, and the outside air is passed through the opening on the peripheral side of the cap through the connection passage to the hole in the portion facing the inner blade. Incorporates inside the cap to promote foam formation.

Next, when the generation of bubbles inside the cap progresses, the excessive bubbles inside the cap block the opening of the cap to stop the air supply, and the excessive bubbles pass through the connection passage from the opening. It is circulated and supplied into the cap through the through hole. Then, the viscosity of the foam inside the cap increases and the convection of the foam occurs, so that the foam has a sufficient cleaning effect.

In this way, when the generation of bubbles inside the cap progresses, excess bubbles overflowing from the cap are supplied to the inside of the cap instead of supplying air.
It increases the viscosity of the foam and accelerates the transition to the stage where the foam flows. As a result, the time from the stage where foam generation proceeds to the stage where the foam grows and its viscosity increases and the foam flows and a sufficient cleaning effect is obtained, compared with the conventional means. It can be shortened. Therefore, it is possible to shorten the time required for cleaning the bubbles for removing the whiskers and the like.

Moreover, by adopting the above-described structure for the bubble cleaning cap, instead of supplying air to the inside of the cap, the action of automatically supplying excess bubbles overflowing from the cap to the inside of the cap is automatically achieved. It can be carried out.

An opening 38 that communicates with the whisker storage space a is formed in a portion where the opening / closing ring 37 is fitted, and an opening 39 is formed in the opening / closing ring 37. The opening / closing ring 37 covers the opening 38 by the rotation of the opening / closing ring 37,
Alternatively, the opening 39 overlaps the opening 38 to open the opening 38.

A battery for power supply and a circuit board (neither shown) are provided inside the grip portion 23 of the main body case 21, and an operation knob 40 is provided outside.

Reference numeral 41 denotes a bubble cleaning cap. The cap 41 surrounds the outer blade 32, the outer blade stand 33 and the rising edge wall 31 of the lid 26 from the outside through a space, and is a disc. It has a head portion 41a and a peripheral side portion 41b surrounding the head portion 41a. A seal ring 42 and a retaining ring 43 that presses the seal ring 42 are attached to the edge of the peripheral side portion 41b, and the cap 41 covers the lid 26.
The seal ring 42 comes into contact with the outer surface of the peripheral side portion of the lid body 26, and the holding ring 43 detachably engages with the ridge 26a formed on the lid body 26 when fitted to. There is.

A hole 44 for air intake and excess bubble circulation for communicating the inside and the outside is formed in a portion of the head 41a of the cap 41 facing the inner blade, for example, a central portion in the diametrical direction. The peripheral wall 41b is formed with an opening 45 for communicating air between the inside and the outside thereof for intake of air and discharge of excess bubbles. The opening 45 is formed by being surrounded by a tubular body. Here, the hole 44 and the opening 45 are connected via the connection passage pipe 46. That is,
One end of the connection passage pipe 46 is inserted into the hole 44, and the other end is inserted into a hole formed in a cylinder forming the opening 45. The opening area of the opening 45 is larger than that of the hole 44.

A case where the electric shaver thus constructed is washed with bubbles will be described with reference to FIG.

First, the opening / closing ring 37 is rotated to align the opening 39 with the opening 38 of the rising edge wall 31 of the lid 26 and open the opening 38. Further, the cap 41 is put on the rising edge wall 31 of the lid 26 to bring the seal ring 42 into contact with the rising edge wall 31 by elastic force, and the pressing ring 43 is engaged with the protrusion 26 a of the lid 26.

As shown in FIG. 4A, the main body case 21 has a grip portion 23 so that the head portion 22 is on the lower side and is horizontal. In this case, the opening 45 of the cap 41 is positioned upward.

First, as shown in FIG. 4A, the detergent aqueous solution S is injected into the inside of the cap 41 through the opening 45 of the cap 41. The injected detergent aqueous solution S has a space b inside the cap 41 and a whisker storage space a inside the outer blade 32.
Accumulate in. The detergent aqueous solution S is injected until the detergent aqueous solution S stored in the cap 41 reaches a preset water level.

Then, as shown in FIG. 4B, the operating knob 40 is operated to rotate the motor 24. The rotation of the motor 24 causes the inner blade base 34 to rotate via the output shaft 25 and the drive shaft 47, and the plurality of inner blades 35 attached to the inner blade base 34 also rotate together. While rotating the plurality of inner blades 35, the detergent solution S injected into the space b inside the cap 41 and the whisker-holding space a inside the outer blade 32, and the air existing in both spaces a and b as well. Stir. As a result, the detergent aqueous solution S and the air are stirred to generate bubbles.

At the same time, the rotation of the inner blade base 34 and the inner blade 35 causes a negative pressure in the central portion of the inner blade base 34, that is, the diametrical center portion of the cap 41. This negative pressure serves as a suction force, and the air outside the cap 41 is sucked from the opening 45 in the peripheral side portion of the cap 41 and passes through the connection passage pipe 46 connected to the opening, and the hole 44 in the central portion of the cap 41 is formed. And flows into the inside of the cap 41. The inflowing air is agitated together with the detergent aqueous solution S by the rotation of the plurality of inner blades 35 in the space b inside the cap 41 and the beard accumulating space a, and the generation of bubbles contributes. Thus, the supply of external air promotes the initial generation of bubbles.

Next, the space b inside the cap 41
When bubbles are generated and grow in the whisker storage space a inside the outer blade 32, the excess bubbles overflow into the opening 45 of the cap 41 as shown in FIG. 4C. Then, the bubbles overflowing into the opening 45 of the cap 41 close the opening 45 and also flow from the opening 45 through the connection passage pipe 46 and the hole 44 into the space b inside the cap 41. As a result, the supply of air from the opening 45 through the connection passage pipe 46 and the hole 44 to the inside of the cap 41 is stopped, and excess bubbles that have overflowed are supplied to the inside of the cap 41 again. It

Then, as described above, the excess bubbles are removed by the cap 4
The viscosity of the bubbles is increased by being supplied to the bubbles inside 1, and the supply of air is stopped, so that the inner blade base 34 and the inner blade 35 are rotated as shown in FIG. The convection of bubbles occurs in the space b inside the cap 41 and the whisker storage space a inside the outer blade 32. The convection of bubbles with high viscosity in this way increases the friction between the bubbles and the surfaces of the lid 26, the outer blade 32, the inner blade base 34 and the inner blade 35, and adheres to these surfaces. Strips of shavings are stripped off. That is, the effect of cleaning the bubbles is enhanced, and sufficient cleaning for removing whiskers and the like due to the bubbles is performed.

In this way, when the generation of bubbles inside the cap 41 progresses, excess bubbles overflowing from the cap are supplied to the inside of the cap 41 instead of supplying air to the inside of the cap 41. This strongly increases the viscosity of the foam and strongly promotes the transition to the stage where the foam flows. For this reason,
Compare the time from the stage of foam generation to the stage where the viscosity of the foam rises and the foam flows and a sufficient cleaning effect is obtained, compared with the conventional means that simply supplies air inside the cap. It can be greatly shortened. Therefore, it is possible to shorten the time required for cleaning the bubbles for removing the whiskers and the like.

Here, by adopting a construction in which the hole 44 is formed in the central portion of the cap 41 and the opening 45 is formed in the peripheral side portion, and the hole 44 and the opening 45 are connected by the connection passage pipe 46, When the generation of bubbles inside the cap 41 has progressed, excess bubbles overflowing from the cap 41 are replaced with air by supplying air to the inside of the cap 41.
The action of supplying the inside of 1 can be automatically performed.

After the cleaning is completed, the cap 41 is removed from the lid 26, and the outer blade 32, the inner blade base 34 and the inner blade 35, and the lid 26 are washed with water and dried.

The present invention is not limited to the above-mentioned embodiments, but can be modified in various ways. For example, the holes formed in the foam cleaning cap, the openings, and the connection passages connecting the two are not limited to the configurations of the embodiments.

[0035]

As described above, according to the rotary electric shaver of the present invention, a cap for covering the head portion of the main body case during light washing is prepared, and a hole is formed in the portion of the cap facing the inner blade. Along with forming an opening on the peripheral side,
These holes and openings are connected by a connecting passage pipe, and when bubbles are generated inside the cap during bubble washing, excess bubbles overflowing from the cap are replaced instead of supplying air to the inside of the cap. Since it is supplied to the inside of the cap, the time from the stage of foam generation to the stage where the foam grows and its viscosity increases and the foam flows to obtain a sufficient cleaning effect is compared with the conventional time. Can be significantly shortened. Therefore, it is possible to shorten the time required for cleaning the bubbles for removing the whiskers and the like.

Moreover, by adopting the above-mentioned structure for the bubble cleaning cap, instead of supplying air to the inside of the cap, the action of automatically supplying excess foam overflowing from the cap to the inside of the cap is automatically performed. It can be carried out.
