  Hereinafter, the present invention will be described through embodiments of the invention. The following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a view showing the appearance of the portable cleaning apparatus 101. The portable cleaning device 101 includes a main body part 110 and a support part 130 that are coupled at one end by a hinge part 140.

  The main body 110 includes an outer shell 112, a vibrator 120, and a diaphragm 121. The outer shell portion 112 has a thin dome shape protruding downward in the drawing. The diaphragm 121 has a flat disk shape and is supported from the inner surface of the outer shell portion 112 via the waterproof seal portion 124 at a position slightly recessed from the upper end of the outer shell portion 112. The diaphragm 121 is formed of a plate material such as hard resin or metal.

  The waterproof seal portion 124 is formed of an elastic material such as an elastomer, and seals between the outer shell portion 112 and the diaphragm 121 in a watertight manner. Therefore, even when the portable cleaning device 101 is immersed in a liquid, the space surrounded by the outer shell portion 112 and the diaphragm 121 is not submerged.

  The vibrator 120 has a disk shape having a diameter equal to or smaller than that of the vibration plate 121, and the lower surface of the vibration plate 121 in the drawing within a space surrounded by the outer shell portion 112 and the vibration plate 121. It is in close contact with. For this reason, when the vibrator 120 vibrates, the vibration propagates to the diaphragm 121 and is further radiated toward the support portion 130 inside the outer shell portion 112.

  The support part 130 includes an outer shell part 132 and a support plate 134. The outer shell portion 132 has a thin dome shape that protrudes upward in the figure, symmetrically with the outer shell portion 112 of the main body portion 110. The support plate 134 is disposed on the same plane as the lower end portion of the outer shell portion 132 in the figure, and forms a flat support surface on the lower surface of the support portion 130 in the figure.

  The outer shell portion 112 of the main body portion 110 and the outer shell portion 132 of the support portion 130 are connected by a hinge portion 140 at one end on the back side with respect to the paper surface. For this reason, the support portion 130 is also connected to the vibrator 120. In the state shown in the figure, the main body part 110 and the support part 130 are separated from each other on the side opposite to one end connected by the hinge part 140, and the portable cleaning device 101 as a whole has one end opened like a two-shell.

  FIG. 2 is a diagram showing a form when the portable cleaning apparatus 101 is carried. Since the support part 130 rotates with respect to the main body part 110 using the hinge part 140 as a rotation axis, the portable cleaning device 101 closes the end parts of the outer shell parts 112 and 132 that are separated in the state shown in FIG. be able to. Thereby, the surface of the vibrator 120 can be accommodated and protected inside the ellipsoidal shell formed by the outer shell portions 112 and 132.

  Further, by closing the outer shell portions 112 and 132, the overall shape of the portable cleaning device 101 becomes thin, so that it is easy to carry. In addition, the diameter of the outer shell parts 112 and 132 is, for example, about several centimeters, and can be set to a size that fits in the palm when folded as illustrated.

  FIG. 3 is a diagram for explaining a usage state of the portable cleaning device 101. When the portable cleaning device 101 is used, the outer shell portions 112 and 132 are closed with the object to be cleaned 150 sandwiched between the main body portion 110 and the support portion 130 once opened. The cleaning target 150 is in a state along the support plate 134 of the support unit 130 and is held at a position facing the vibrator 120. Thereby, in the portable cleaning device 101, even a flexible material such as a textile product is held in a state of facing the vibrator 120 in parallel.

  It should be noted that the object to be cleaned 150 is relatively thin film-like or seed-like, for example, a textile product such as clothing or handkerchief in light of carrying the portable cleaning device 101 sandwiched between the main body 110 and the support 130. Are preferred. As will be described later, the object to be cleaned 150 is cleaned while immersed in a cleaning liquid such as water.

  The portable cleaning apparatus 101 sandwiching the object to be cleaned 150 is immersed in cleaning water 182 stored in a container 180 after connecting an external unit 200 described later. Here, the container 180 may be any container that can store a liquid, such as a wash basin, a pole, a bucket, or a bat. Further, instead of the independent container 180, a bowl of a washstand, a bathtub, or the like may be used as the container 180.

  The cleaning water 182 may be simple tap water, but may be water mixed with a surfactant, alkaline electrolyzed water generated for cleaning (so-called alkaline ionized water), or the like. When cleaning by the portable cleaning device 101 is started, a state in which a contaminant such as the object to be cleaned 150 is filled with the cleaning water 182 in a state where no gas such as the atmosphere exists between the vibrator 120 and the vibrator 120. It is preferable that

  The external unit 200 includes a power supply unit 170, a switch 190, and a drive unit 160. The power supply unit 170 is a power supply source that is consumed when the portable cleaning apparatus 101 operates. The switch 190 is an electric switch that controls whether or not the power output from the power supply unit 170 is supplied to the drive unit 160. For example, the drive unit 160 is configured as an oscillation circuit that is operated by power supplied from the power supply unit 170. In this embodiment, the drive unit 160 generates drive power whose voltage fluctuates in a so-called ultrasonic band cycle.

  More specifically, vibration having a frequency of 10 kHz or more and 100 lHz or less may be used. For example, in the case of washing textile products such as clothes, vibrations in a band of 20 kHz or more and 50 kHz or less can be preferably used.

  The external unit 200 is coupled to the portable cleaning device 101 via a power supply cord 172 including a pair of insulated wires 171 and a connection portion 116, for example. Inside the portable cleaning device 101, the two insulated wires 171 separated at the connection portion 116 are electrically coupled to the vibrator 120.

  The connection portion 116 and the outer shell portion 112 are also sealed watertight by the waterproof seal portion 115. As a result, the power supply cord 172 to which the drive power supplied from the external unit 200 is applied and the connection portion 116 come into contact with the cleaning water 182, and the drive portion 160 is prevented from being damaged due to a short circuit of the insulated wire 171. .

  The vibrator 120 to which driving power is supplied from the driving unit 160 is a piezoelectric element formed of a piezoelectric material formed by, for example, compression molding or sintering. Since the volume of the piezoelectric element changes according to the magnitude of the applied voltage, an electric signal whose voltage fluctuates is converted into mechanical vibration. Further, the vibration of the vibrator 120 is transmitted to the medium inside the outer shell portion 112 via the diaphragm 121.

  FIG. 4 is a block diagram of the portable cleaning apparatus 101 in the operating state. Driving power is supplied to the vibrator 120 of the portable cleaning apparatus 101 from the external unit 200 connected to the outside of the portable cleaning apparatus 101.

  Here, in the external unit 200, when the switch 190 is turned on, power is supplied from the power supply unit 170 to the drive unit 160. The electric power supplied here is, for example, a DC voltage supplied from a charged secondary battery. The power source of the power supply unit 170 is not limited to a secondary battery, and may be a dry battery or a power adapter that converts a commercial power source into a DC voltage.

  The driving unit 160 generates and outputs a driving voltage whose voltage periodically changes from the supplied power. Here, the fluctuation period of the drive voltage generated by the drive unit 160 is preferably a so-called ultrasonic band of 20 kHz or more. The ultrasonic band generally means a band higher than the human audible band, but may have a frequency of about several hundred Hz if a sufficient amplitude is obtained for the driving power.

  When a driving voltage is applied from the driving unit 160, the vibrator 120 vibrates the vibration plate 121 according to the vibration amplitude and vibration period of the driving voltage, and the vibration of the vibration plate 121 vibrates the cleaning water 182. The object 150 to be cleaned sandwiched between the vibration plate 121 and the support plate 134 is subjected to an impact due to the ultrasonic vibration generated by the vibrator 120 through the cleaning water 182. Due to this impact, the contaminants attached to the object to be cleaned 150 are peeled off and the object to be cleaned 150 is cleaned.

  FIG. 5 is a schematic cross-sectional view showing the structure of another portable cleaning apparatus 102. The portable cleaning device 102 has the same structure as the portable cleaning device 101 shown in FIG. Therefore, the same reference numerals are assigned to common components, and redundant description is omitted.

  The portable cleaning device 102 has a structure different from the portable cleaning device 102 in that the portable cleaning device 102 includes a drive unit 160 that is built in the outer shell portion 112 of the main body 110 and is directly connected to the vibrator 120. As a result, the power supply unit 170 that supplies power from the outside of the portable cleaning device 102 may supply simple power instead of driving power that changes periodically.

  Therefore, for example, by setting the power supply voltage to 5 volts defined by the USB (Universal Serial Bus) standard, a general-purpose power supply such as a so-called mobile battery can be used. In addition, a USB terminal or the like provided on the personal computer can be used as the power supply unit 170. However, in order for the portable cleaning apparatuses 101 and 102 to achieve the desired cleaning effect, it is desirable to apply power of about 20 W. Therefore, when the power supply voltage is 5V, a current supply capability of about 4 A is required for the power supply.

  FIG. 6 is a schematic cross-sectional view showing the structure of another portable cleaning apparatus 103. The portable cleaning device 103 has the same structure as the portable cleaning device 102 shown in FIG. Therefore, the same reference numerals are assigned to common components, and redundant description is omitted.

  The portable cleaning device 103 has a different structure from the portable cleaning device 102 in that it includes a power supply unit 170 built in the outer shell 132 of the support unit 130. The power supply unit 170 is, for example, a secondary battery, and is coupled to a drive unit 160 built in the main body unit 110 via a power supply cord 172. Thereby, the portable cleaning apparatus 103 can be used independently without using an additional member such as the external unit 200.

  In the example shown in FIG. 6, the outer shell portion 132 of the support portion 130 is also provided with a connection portion 136 connected to the power supply portion 170. As a result, the power supply unit 170 and the drive unit 160 are electrically coupled by the power supply cord 172 disposed outside the outer shell portions 112 and 132. Further, the respective connection portions 116 and 136 are sealed in a watertight manner by the waterproof seal portions 115 and 135 so that the connection portions 116 and 136 are not brought into contact with the cleaning water.

  Further, in FIG. 6, the power supply cord 172 connected via the connection portions 116 and 136 is explicitly shown as described above in order to clarify the structure. However, it is practically preferable that the power supply cord 172 is not exposed to the outside through the inside of the outer shell portions 112 and 132.

  Furthermore, in order to charge the secondary battery of the power supply part 170, the portable washing | cleaning apparatus 103 may be provided with the connection part connected to the exterior. Furthermore, a power supply coil may be provided inside the outer shell portion 132 of the support portion 130 so that the power supply portion 170 can be charged without providing a connection portion exposed to the outside.

  FIG. 7 is a schematic cross-sectional view showing the structure of another portable cleaning device 104. The portable cleaning device 104 has the same structure as the portable cleaning device 103 shown in FIG. Therefore, the same reference numerals are assigned to common components, and redundant description is omitted.

  The portable cleaning device 104 has a structure different from that of the portable cleaning device 103 in that a transformer 174 and a power supply cord 175 are provided in the outer shell portion 132 of the support portion 130. The power feeding cord 175 passes through a part of the outer shell portion 132 and electrically connects the inside and outside of the outer shell portion 132. A portion of the outer shell portion 132 through which the power feeding cord 175 passes is sealed in a watertight manner by a waterproof seal portion 137. Accordingly, when the portable cleaning device 104 is immersed in the cleaning water 182, the cleaning water 182 is prevented from being immersed inside the outer shell portion 132.

  One end of the power feeding cord 175 is connected to the transformer 174 inside the outer shell 132. The other end of the power supply cord 175 is fitted with a plug 176 to be inserted into a so-called wall outlet outside the outer shell portion 132. As a result, power from the commercial power source is supplied to the transformer 174 via the power supply cord 175.

  The transformer 174 converts the AC voltage supplied from the commercial power source into a DC voltage that drives the driving unit 160, and supplies power to the driving unit 160 via the power supply cord 172. Further, drive power is supplied from the drive unit 160 to the vibrator 120 through the insulated wire 173. Thereby, the portable washing | cleaning apparatus 104 can operate | move, receiving supply of abundant electric power from a commercial power source. In addition, the transformer 174 may be designed to be used overseas, so that the portable cleaning device 104 can be used on the road.

  In the example shown in FIG. 6, the power feeding cord 175 directly connects the transformer 174 to the plug plug 176. However, providing a switch between the transformer 174 and the plug 176 makes it easier to use the portable cleaning device 104 when the container 180 for the cleaning water 182 and the wall outlet are separated.

  FIG. 8 is a schematic cross-sectional view showing the structure of another portable cleaning apparatus 105. The portable cleaning device 105 has the same structure as the portable cleaning device 101 shown in FIG. Therefore, the same reference numerals are assigned to common components, and redundant description is omitted.

  The portable cleaning device 105 has a structure different from that of the portable cleaning device 101 in that the support unit 130 includes another vibrator 122 and a diaphragm 123. The vibrator 122 and the diaphragm 123 are symmetrically opposed to the main body 110 side. Further, a space between the periphery of the diaphragm 123 and the inner surface of the outer shell portion 132 of the support portion 130 is sealed in a watertight manner by the waterproof seal portion 125.

  The portable cleaning device 105 does not include the drive unit 160, the power supply unit 170, the transformer 174, and the like. The other ends of the insulated wires 177 and 178 whose one ends are connected to the vibrators 120 and 122 are connected to the connecting portions 116 and 136. Therefore, as shown in FIG. 3, the portable cleaning device 105 uses the external unit 200 having the drive unit 160, the power supply unit 170, and the switch 190 by connecting to the connection units 116 and 136.

  Further, waterproof seal portions 115 and 135 are provided around the connection portions 116 and 136. This prevents water from entering the outer shell portions 112 and 132 from the connection portions 116 and 136.

  In the portable cleaning device 105, the diaphragm 123 also serves as a support plate 134 for the vibrator 120 on the main body 110 side. At the same time, the vibration plate 121 on the main body 110 side also serves as a support plate 134 for the vibrator 122 on the support portion 130 side.

  With the above-described structure, ultrasonic vibration can be applied from the front and back to the object to be cleaned 150 sandwiched between the main body 110 and the support part 130 in the portable cleaning device 105. As a result, the cleaning power of the portable cleaning device 105 is increased, and contamination by highly adhering contaminants such as cosmetics and seasonings having high viscosity and high wettability can be cleaned.

  Note that the phases of the ultrasonic vibrations generated by the pair of vibrators 120 and 122 may be the same or different. In addition, when the intensity of ultrasonic vibration applied to the object to be cleaned 150 is excessively high, the impact generated by the ultrasonic waves may damage the object to be cleaned 150. Therefore, the external unit 200 that supplies driving power to the portable cleaning device 105 may be provided with a function of adjusting the driving power to be supplied, for example, the voltage amplitude and period.

  FIG. 9 is a schematic cross-sectional view showing the structure of another portable cleaning device 106. FIG. 9 also shows a part of the object 150 to be cleaned for explanation.

  The portable cleaning device 106 has the same structure as the portable cleaning device 105 shown in FIG. Therefore, the same reference numerals are assigned to common components, and redundant description is omitted.

  The portable cleaning device 106 has a different structure from the portable cleaning device 105 in that the main body 110 and the hinge portion 140 are connected via a short link portion 148 and another hinge portion 144. . The portable cleaning device 106 is different from the portable cleaning device 105 in that the support portion 130 and the hinge portion 140 are connected via a short link portion 146 and another hinge portion 142. Have

  The pair of link portions 146 and 148 are rotatably connected to the support portion 130 or the main body portion 110 using the other hinge portions 142 and 144 as rotation axes. The pair of link portions 146 and 148 are coupled to each other so as to be rotatable about the hinge portion 140 as a rotation axis. Here, the hinge portions 142 and 144 each have a rotation axis parallel to the hinge portion 140.

  Thereby, in the portable washing | cleaning apparatus 106, the space | interval of both can be expanded, maintaining the parallelism with the vibrator | oscillator 120 in the main-body part 110, and the support plate 134 in the support part 130. FIG. Thereby, as shown in the drawing, when the thick object 150 is cleaned, the entire surface of the vibrator 120 can be operated with respect to the object 150 under uniform conditions.

  Note that the above-described structure of the portable cleaning device 106 is suitable for cleaning the thick object 150 to be cleaned. Therefore, in order to increase the cleaning power by ultrasonic vibration, it is effective to have a structure in which the object 150 to be cleaned is sandwiched between a pair of vibrators 120 and 122, but a structure having a single vibrator 120 is also possible. Of course it is good.

  As described above, according to the present invention, when carrying, the vibrator 120 is protected inside the outer shell portions 112 and 132 for easy carrying. Portable cleaning devices 101, 102, 103, 105, and 106 that can be efficiently cleaned with a pinch interposed therebetween are provided. Thereby, the washing | cleaning by ultrasonic vibration can be easily utilized at the place.

  In the above example, the portable cleaning devices 101, 102, 103, 105, and 106 are formed using the thin dome-shaped circular outer shell portions 112 and 132. However, the shape of the outer shell portions 112 and 132 is not limited to a dome shape. For example, the outer shell portions 112 and 132 may each have a disk shape having a substantially uniform depth, or may have another shape such as a rectangle. Further, when the power supply unit 170 or the like is not accommodated on the support unit 130 side, the support unit 130 may be a solid plate-like member. Furthermore, the shapes of the outer shell portions 112 and 132 may be different from each other.

  In the above example, the structure in which the main body part 110 and the support part 130 are connected by the hinge part 140 has been described. However, the structure for connecting the main body part 110 and the support part 130 is not limited to the hinge. For example, the main body part 110 and the support part 130 may be connected by a string-like member or a rod-like member, or may be a structure other than a mechanical connection structure such as a magnetic force. It may be connected.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

  The order of execution of each process such as operations, procedures, steps, and stages in the apparatus, system, program, and method shown in the claims, the description, and the drawings is particularly “before” or “prior to”. It should be noted that the output can be realized in any order unless the output of the previous process is used in the subsequent process. Regarding the operation flow in the claims, the description, and the drawings, even if it is described using “first”, “next”, etc. for convenience, it means that it is essential to carry out in this order. It is not a thing.
