  A float mechanism for floatingly supporting the razor head 2 can be provided between the razor head 2 and the display unit 3.

In the electric razor according to the present invention, the main body part 1 also serving as a grip, the function part 2, and the display part 3 for displaying device information form an outer structure, and the display part 3 is adjacent to the grip part of the main body part 1. Since it arrange | positions, in the state which hold | maintained and hold | maintained the main-body part 1 with the hand, it can prevent that the display part 3 is covered with a hand. Therefore, according to the present invention, when the electric razor is gripped and used, the operating state of the electric razor can be clearly known by visually recognizing the device information display 24 displayed on the display unit 3. .

When at least a part of the display unit 3 is constituted by a transparent display panel 23 so that the device information display 24 provided on the display panel 23 can be seen from both the front and back surfaces, the operation state is indicated by the device information display 24 reflected in the mirror. Can be confirmed. Further, when the device information display 24 is switched to the non-display state, the skin state can be reflected in a mirror through the transparent display panel 23, so that it is possible to accurately check the skin state and the presence or absence of a shaved beard. You can shave.

The display element of the device information display 24 can be composed of at least one of a character, a graph, a flickering light or a difference in emission color, and the display information can be displayed by configuring the device information display 24 by combining different display elements. It becomes more specific and diverse. In particular, if the display panel 23 is composed of a liquid crystal panel, the display elements can be displayed in any combination, so that the device information display 24 is easy for the user to understand, and in addition to the driving state information, an electric razor Display contents such as unique information and maintenance information can be diversified.

  When the main unit 1 and the functional unit 2 are connected via the display unit 3 disposed between them, the display unit provided near the hand while preventing the display unit 3 from being covered with the hand 3 device information display 24 can be seen. For example, when the display unit 3 is provided on the side of the main unit 1, the display unit 3 may become an obstacle when the main unit 1 is gripped or changed. is there.

  When the main body 1 includes a front curved surface 10 and a rear curved surface 11 that are each bulged in a protruding shape, and the left and right sides are formed in a flat egg shape, the main body 1 is gripped with one hand The whole peripheral surface of the main body 1 can be held so as to be completely wrapped with the first to fifth fingers. Therefore, the ease of gripping is significantly improved compared to conventional electric razors, and it is possible to maintain the gripped state with a smaller force, and for users with weak gripping force or users who have difficulty in finger joint freedom. Even if there is, we can grip electric razor without difficulty. When the longitudinal center axis K along the longitudinal center of the electric razor is substantially perpendicular to the longitudinal center axis L of the functional unit 2 in plan view, there is no need to be aware of it when the main body 1 is grasped with one hand. Since the functional unit 2 naturally faces the user, it is not necessary to adjust the position of the electric razor by holding the hand after gripping it once, and it is a user with weak grip strength or a user who does not have freedom of finger joints. However, it can be used with the electric razor securely held.

In comparison, the main body 1 is small and compact, and in the state where the main body 1 is gripped, the entire peripheral surface can be held so as to be completely wrapped with one hand.

  When the main body 1 and the functional unit 2 are connected by the display unit 3 having a small front and rear thickness, the appearance of the electric razor, particularly the impression seen from the side, is slim and light. Further, the upper end of the rear curved surface 11 of the main body unit 1 intersects the base end portion of the display unit 3 at a large angle, and the rear finger rest 30 is formed on the upper end of the rear curved surface 11, whereby the main body unit 1. Can be gripped along the rear curved surface 11 from various directions, obliquely upward, rearward, and obliquely downward, so that the body part 1 that is easier to grip can be obtained, and the body part 1 can be securely held with a smaller force. it can.

  When the display unit 3 is formed in an inverted triangle shape from the left and right side surfaces of the narrow body unit 1 to the both sides of the lower surface of the horizontally long functional unit 2, the ease of gripping the body unit 1 is maintained. However, the movement of the hand gripping the main body unit 1 toward the functional unit 2 side is received and regulated at both side edges of the display unit 3, so that even when the gripping force is weak or the freedom of finger joints is difficult, it is more reliable. The main body 1 can be gripped and held.

  When the upper surface of the main body 1 and the front and rear halfway portions of the lower surface of the functional unit 2 are connected by the display unit 3 having a small front and rear thickness, the impression when the electric razor is viewed from the side is more slim and light. In addition to this, delicateness is added, and in combination with the appearance of the egg-shaped main body 1 provided at the lower portion of the display unit 3, a more innovative design effect is exhibited. Since the second finger can be received by the display unit 3 in a state where the main body unit 1 is held and held, a more stable grip mode can be obtained.

  When the rear curved surface 11 of the main body 1 is formed in a canopy shape, each finger is kept in a state where the finger joints of the second to fifth fingers are naturally bent in a state where the main body 1 is gripped. Can be fitted to the shape of the rear surface of the main body 1, so that the ease of gripping the main body 1 can be improved and more reliably held.

  When the bending radius of the front curved surface 10 of the main body 1 is set larger than the curved radius of the rear curved surface 11, each of the second to fifth fingers applied to the rear curved surface 11, and the front curved surface The main ball 1 that catches the surface 10 can securely hold the main body 1 in a stable state, so that the main body can be held in a more stable state even when the gripping force is weak or the finger joint is difficult to operate. 1 can be held.

  The display part 3 is comprised by the base part 3a fixed to the main-body part 1 with the inverted triangular connection part 3b, and the cross section of the main-body part 1 located behind the base part 3a is formed in the parabolic shape. The main body 1 can be formed into an egg shape with a small left-right width and a large front-back width, and the main body 1 can be gripped and held in a more natural grip form.

  When the connecting portion 3b of the display unit 3 is formed in a plate shape, the light razor and the delicate feeling can be emphasized by further simplifying the appearance of the electric razor. The plate-like connecting portion 3b is simplified in shape and structure, and can be manufactured at a low cost.

  When at least a part of the connecting portion 3b of the display unit 3 is formed of a transparent material, the skin surface after shaving reflected in the mirror can be visually recognized through the transparent portion while using an electric razor. Moreover, shaving can be performed effectively.

  If the display part 3 is provided in the connection part 3b, the driving | running state of an electric shaver can be confirmed by simple operation which only puts the display part 23 into a visual field, with the state which hold | maintained the main-body part 1. FIG.

  If the display panel 23 is formed so as to expand upward along the left and right side edges of the connecting part 3b of the display part 3, the most part of the connecting part 3b can be used as the display panel 23. The display can be expanded to display various displays.

  When the entire display panel 23 is formed of a transparent material and the operation display displayed on the display panel 23 is visible from the front and back, the operation state of the electric razor is confirmed by the device information display 24 reflected in the mirror. Can do. For example, even when shaving from the throat to the chin, it is possible to confirm the driving state by visually recognizing the device information display 24 reflected in the mirror.

  When the razor head 2 is supported in a floating manner by a float mechanism provided between the razor head 2 and the display unit 3, the razor head 2 is moved up and down or tilted left and right along the skin surface to effectively cut the beard. Yes. Since the float mechanism is provided between the display unit 3 and the razor head 2 that do not incorporate any equipment, the float mechanism can be simplified.

When the posture of the razor head 2 is changed by applying the fingertip ball of the thumb to either the left or right front finger support 28, the display unit 3 is as much as the left and right positions of the front finger support 28 are separated from the vertical center axis of the display unit 3. By increasing the moment acting on the razor head, the posture of the razor head 2 can be changed easily with a smaller force.

  By making the left and right width H of the main body 1 larger than the front and rear width A of the razor head 2, the razor head 2 side is made slim and light while making the appearance of the main body 1 look solid. It can be put together and the overall impression of an electric shaver can be made to resemble a T-shaped shaver, creating a novel design that blends a profound feeling with a light feeling.

  As described above, when the main body 1 and the razor head 2 are connected via the connecting portion 3b having a small front-rear thickness and the rear case 1b is formed in a canopy shape, as shown in FIG. Since the rear finger rest 30 for mainly placing the fingertip of the second finger is formed between the base end of the connecting portion 3b, the main body portion 1 can be gripped in a more stable state.

  Since the display unit 3 is disposed between the switch button 7 of the main unit 1 and the razor head 2, the contents of the device information display 24 displayed on the display unit 3 can be easily confirmed. When the display unit 3 is in the vicinity of the razor head 2 and in use, shaving is often performed by placing a thumb near the position where the switch button 7 is turned on. This is because it can be prevented from being obscured.

  FIG. 6 shows another embodiment in which the display unit 3 is changed. In this case, the display panel 23 is composed of a transparent liquid crystal panel so that the device information display 24 can be displayed as characters, graphs, and pictographs. Specifically, when the switch button 7 is turned on, the operation mode is displayed by the character display 24a, and the remaining battery level is displayed by the pictograph 24b and the bar graph 24c. The remaining battery level (%) can be displayed as a numerical value, or the remaining time (minutes) can be displayed as a numerical value as the usable time of the electric razor.

  The operation mode can be switched to one of four types of sensor mode, mild mode, powerful mode, and turbo mode by pressing the select button 33 arranged below the switch button 7, and depending on each mode. The character display 24a is changed. In the sensor mode, the load current of the motor 14 is detected, and the driving rotational speed of the inner blade 17 is automatically changed. In the mild mode, the driving rotational speed of the inner blade 17 is fixed at 2500 rpm. Similarly, in the powerful mode, the driving speed of the inner blade 17 is fixed at 3000 rpm, and in the turbo mode, the driving speed of the inner blade 17 is fixed at 3500 rpm.

  Also in this embodiment, since the device information display 24 can be seen from both the front and back surfaces of the display panel 23, the operating state of the electric razor can be confirmed by the device information display 24 reflected in the mirror. When the device information display 24 is switched to the non-display state, the skin state can be reflected on the mirror via the transparent display panel 23, so that the user can shave while checking the skin state and the presence or absence of the shaved hair.

  When the display panel 23 is composed of a liquid crystal panel, not only the operation state information but also the specific information of the electric razor such as main specifications and manufacturing information, and the maintenance information of the electric razor, for example, the charging time is approaching. Information such as that the replacement time of the inner blade 17 or the outer blade 18 is approaching, that fuzz cleaning is necessary, or the accumulated usage time of the electric razor can be displayed as necessary. Since others are the same as the previous embodiment, the same reference numerals are given to the same members including the following embodiments, and the description thereof is omitted.

  If necessary, the window 22 may be formed in a circle, an ellipse, or a rectangle. In the display unit 3 shown in FIG. 1 or FIG. 6, when the window 22 is circular and the diameter thereof is F, the area of the display panel 23 is increased by setting the dimensional relationship of each part to F≈I> H. A clear and easy-to-see display unit 3 can be configured. The display unit 3 does not need to be S-shaped in a side view and can be formed in a flat plate shape.

  The main body 1 does not necessarily have a flat oval shape. For example, the front shape of the front case 1a can be formed into an indented curved shape or a flat shape. The dimension of each part in the electric razor is preferably the dimensional ratio described above, but if necessary, the front-rear thickness B of the connecting part 3b and the front-rear dimension C of the main body part 1 can be made the same. In order to enhance the design effect, the front and rear cases 3a and 3b can be extended upward, and the connecting portion 3b can be sandwiched between the extended portions. In that case, the front and rear thickness dimension of the extended part is set to be small so that the dimensional ratios of the respective parts described above can be satisfied.

  The base 3 a can be fastened and fixed to the front surface of the main body 1. If necessary, the display part 3 can be formed only by the connecting part 3b and the base part 3a can be omitted. In that case, the connecting portion 3 b can be formed integrally with the main body portion 1. The switch button 7 does not need to be a push button, and may be a slide button that slides up and down to turn on and off. In that case, by disposing the switch button 7 near the upper end of the front curved surface 10, it is possible to well prevent the switch button 7 switched to the on state from being erroneously switched to the off state. The upper portion of the front curved surface 10 is curved while approaching the base portion 3a. As shown in FIG. 5, in the state where the body portion 1 is gripped and the beard is shaved, the thumb that grips the body portion 1 is included. Since the upward force acts on the upper part of the main body 1 where the switch button 7 is located, the hand is hardly turned off.
