Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an electric shaver whose blade portion, etc., can be washed with water.

[Technical background of the invention and its problems]

FIG. 9 shows an example of the prior art. This electric shaver has an outer wall 2 and an inner wall 3 formed on the upper part of a main body case 1, a drive part cover 5 is provided on the inner wall 3 via a packing 4, and an outer cutter body 6 is attached to and detached from the outer wall 2. Installed as possible. The outer blade body 6 is rotatably attached by a hinge 7, and the hinge 7 is inserted into a sandwich leaf spring 8 provided between the inner and outer walls 2, 3. In the figure, reference numeral 9 denotes an inner cutter body 1 in which a plurality of inner cutters that are in sliding contact with the inner surface of the outer cutter body 6 are arranged side by side at intervals and are reciprocated along the direction of the arrangement.
0 is an outer blade clamp, 11 is a motor, and 12 is a drain hole. To wash this electric shaver, remove the clamp 10, rotate the outer blade 6 about the hinge 7 in the direction of the arrow in the figure to expose the inner blade 9, and then remove the inner blade 9, etc. It is designed to be washed away by pouring water into it.

However, with this electric shaver, when washing with water, water splashes around and stains the surrounding area. Further, since the parts for opening and closing the outer blade body 6, such as the hinge 7 and the spring 8, are attached between the double walls 2 and 3, assembly, repair and inspection are difficult.
Furthermore, since the spring 8 and the like are exposed to water, they are susceptible to rust.

In addition, according to Japanese Patent Application Laid-Open No. 57-150988, an outer cutter frame supporting an outer cutter is covered with a front cover and a rear cover, and these front and rear covers are respectively mounted so as to be rotatable in the front direction or the back direction by pivots. Additionally, it is known that the outer cutter frame is provided with a cleaning water inlet and an outlet so that the blade can be washed with water by pouring cleaning water through the inlet with the front and rear covers open. ing.

However, with this electric shaver, while it is easy to direct the cleaning water through the inlet between the many inner blades arranged in parallel, the water that has passed between the inner blades is directed along the direction in which these many inner blades are lined up. The inner cutter acts as a resistance to the flow because it flows out through the side outlet opened on the side of the outer cutter frame. Furthermore, although a portion of the water poured from the inlet also flows out through the outer blade (blade plate), the resistance of the outer blade to the flow of water is relatively large. Therefore, the resistance of the water to be discharged increases at the end, resulting in poor washing efficiency.

[Purpose of invention]

The purpose of the present invention is to provide a water-washable electric shaver that can improve the efficiency of washing with water, is easy to assemble, repair and inspect, and reduces the rate of getting wet during washing.

[Summary of the idea]

In order to achieve the above object, the water-washable electric shaver of the present invention forms a space between the main body case and a removable outer blade body that is attached to the upper part of the case so as to protrude forward. An inner cutter body that is reciprocated in sliding contact with the inner surface of the blade plate of the outer cutter body is housed in the inner cutter body, and a discharge port that communicates with the void space and has a horizontally elongated shape along the reciprocating direction of the inner cutter body; Provided on the upper surface of the main body case at a rear position of the outer blade body to open and close the discharge port, and at a position to receive water from the discharge port when washing is performed with the blade plate of the outer blade facing upward. A discharge port cover that is opened and guides the drainage outward away from the main body case is rotatably attached to the outer surface of the main body case via a pivot located at the rear of the outer blade, and the discharge port cover A lid operating body for opening and closing operations is located behind the outer blade body and on the opposite side to the outflow direction in which drainage from the discharge port is guided by the discharge port cover, and It is characterized by being attached to.

In a water-washable electric shaver with such a configuration, in order to wash the blade part with water, operate the lid operating body to open the discharge port by rotating the discharge port cover around the pivot, and then open the discharge port by opening the discharge port. Point upwards and pour water through the outer blade from above. Then,
The water injected into the outer blade body passes through the space and between the inner blades of the inner blade body, and flows out from the discharge port together with the hair shavings and the like adhering to these. In this case, the resistance to flow is greatest in the blade plate of the outer blade body, but since water passes through this part immediately after it has flowed out forcefully from a faucet, etc., it does not have a large effect on flow performance. After that, the water flows along the surface of the inner cutter, along the inner surface of the cavity, and finally flows through the outlet, which has an oblong shape along the reciprocating direction of the inner cutter. , There are few sudden changes in the water flow direction and sudden changes in the passage area, and the resistance to the water flow gradually becomes smaller. Therefore, it is possible to effectively flush out the hair shavings and the like adhering to the inner surface of the blade plate of the outer cutter body, the surface of the inner cutter, and the inner surface of the cavity, and the efficiency of washing with water is high. Further, by washing with water with the blade plate of the outer blade facing upward, the discharge port cover, which is rotated toward the outside of the main body case and opens the discharge port, is positioned below the discharge port. Therefore, water flowing out from the outlet is received by the outlet cover and guided outward away from the main body case. Therefore, water containing shavings is prevented from flowing to the main body case. Moreover, since the lid operating body for opening and closing the discharge opening cover is provided behind the outer cutter body and on the opposite side to the outflow direction of the waste water guided by the discharge opening cover, this lid operating body can be used to remove hair shavings. You can reduce the amount of water that gets wet with drainage water. Therefore, it is possible to reduce the rate at which the main body case and the lid operating body are soiled with beard dregs or wet with water. Furthermore, since the discharge port cover and the cover operating body are provided on the outer surface of the main body case, they can be easily attached to and removed from the main body case, making assembly, repair and inspection easier.

A plurality of inner cutters that are in sliding contact with the outer cutter are arranged side by side at intervals and are reciprocated in the direction of the arrangement. Note that 31 is a PC board, 32 is a seal packing, and 33 is a rubber drive mechanism seal.

A cavity 34 is formed between the main body case 21 and the outer blade 27 to accommodate the inner blade 30. The bottom surface of this space 34 is inclined rearward toward the top surface of the main body case 21, for example. Note that θ in FIG. 2 indicates an inclination angle. Further, a stubble reservoir 35 is formed in the main body case 21 in communication with the lowest position of the bottom surface of the cavity 34. An opening on the side opposite to the opening on the cavity 34 side of this hair scraps reservoir 35 serves as a discharge port 36 and is opened on the upper surface of the main body case 21 at the rear of the outer cutter body 27. In addition, 37 in the figure is the beard waste reservoir 3.
This is an introduction guide to 5. Above beard debris pool 3
5 and the discharge port 36 have a horizontally long shape along the reciprocating direction of the inner cutter body 30, as the discharge port 36 is shown in FIG.

This discharge port 36 is opened and closed by an opening/closing mechanism 38 provided on the outer surface of the main body case 21. In this embodiment, the opening/closing mechanism 38 includes a discharge port cover 39 made of hard resin, a lid operating body 40 made of resin, and an operating body guide 41. The attachment part 42 of the discharge port cover 39 has a pair of slits 43 and a shaft 44, and the cover 39 is located behind the outer blade 27 and has a shaft installed in a bearing hole 45 provided on the outer surface of the main body case 21. 44 and is rotatably attached, and the discharge port 36 is opened and closed by the rotation. Note that the slit 43 allows the mounting portion 42 to be elastically deformed, and the outlet cover 3

consists of a pair of long grooves provided opposite to each other on the outer surface of the main body case 21. The lid operating body 40 attached to the rear of the outer blade body 27 is made of an elastically deformable resin material, and has an arm portion 48 having an engaging pawl 47 at the tip. This lid operating body 40 is positioned in a direction opposite to the outflow direction of the waste water from the discharge port 36 and is attached so as to be slidable along an operating body guide 41. Arm part 4
8 is elastically deformable, and its engaging claw 47 is engaged with the engaging portion 46, and the discharge port cover 3
9 is energized. In addition, 49 is the main body case 21
This is a recessed groove provided on the outer surface of the The outlet cover 39 is closed during use to prevent hair shavings from leaking from the outlet 36.

To wash the inner blade body 30 and the like with water, first, the lid operating body 40 is moved in the direction of arrow A in FIG. 1 to open the discharge port lid 39. In this case, as shown in FIGS. 6 to 8, the arm portion 48 further elastically deforms and moves the discharge port cover 39 approximately 90 degrees around the shaft 44 through the engagement between the engaging claw 47 and the engaging portion 46. Rotate it once to open the discharge port 36. In addition, in this lid opening operation, since the moving direction of the lid operating body 40 and the opening direction of the discharge port lid 39 are the same, there are fewer mistakes in the operation. The open state of the lid 39 is shown in FIG. Next, the second
Pour water from the direction of arrow B. Then, the water passes through the blade plate of the outer blade body 27, flows along the surface of the inner blade of the inner blade body 30, flows into the whisker reservoir 35 along the bottom surface of the cavity 34, and then flows from the discharge port 36 to the whisker reservoir 35. It flows out with the debris. Further, the drained water is received by the discharge port cover 39 as shown by arrow C in FIG. will be guided to. By washing with water as described above, the outer blade body 27, the inner blade body 30, and the empty space 3 are removed.

According to the above-mentioned embodiment, as described above, washing can be performed with the outer cutter body 27 attached, so that it is possible to prevent water containing beard shavings from scattering and staining the surrounding area. Since the discharge port 36 has a horizontally elongated shape along the reciprocating direction of the inner cutter body 30, the injected water flows smoothly between the inner cutters of the inner cutter body 30 and within the space 34, and Since there are few sudden changes in the flow direction and passage area at the waste reservoir 35 and the discharge port 36, the waste flows smoothly toward the discharge port 36. Therefore, the hair chips adhering to the surface of the inner cutter, the hollow space 34, and the inner surface of the hair scraps reservoir 35 are effectively washed away by water, and the hair chips can be easily and reliably removed. The discharged water is guided to the discharge port lid 39 and away from the main body case 21, which prevents the lid operating body 40 side and the hand holding the razor from getting dirty. Since the mechanism 38 is provided on the outer surface of the main body case 21, the drainage water is removed from the main body case 2.
No infiltration into 1. Therefore, it is not necessary to have a complicated structure such as providing a double wall and a drain hole in the main body case 21 or providing packing on the double wall. Even if metal parts are used on the operating section side of the 38, rusting can be prevented. Furthermore, since this embodiment has a beard debris reservoir 35, the number of times of cleaning can be reduced, and since the beard debris reservoir 35 also serves as a drainage channel, accumulated debris can be reliably discharged. After cleaning, the drain port 36 may be closed by pushing up the lid operating body 40 and rotating the drain port cover 39.

In addition, when implementing this invention, the main body case, outer blade body, void space,
