The content shown in the drawings may be exaggerated compared to the actual implementation form of the invention. For the detailed description of the structure that is judged to possibly unnecessarily confuse the gist of the present invention, it will be omitted or briefly described.

[0056] Hereinafter, the embodiments disclosed by the present invention will be described in detail with reference to the accompanying drawings.

[0057] Figure 1 is a perspective view of the ultrasonic cleaning machine 1 according to the embodiments disclosed by the present invention, Figure 2 is an exploded perspective view of the ultrasonic cleaning machine 1 according to the embodiments disclosed by the present invention, Figure 3 is a front view of the ultrasonic cleaning machine 1 according to the embodiments disclosed by the present invention, Figure 4 (a) is a rear view of the ultrasonic cleaning machine 1 according to the embodiments disclosed by the present invention, and Figure 4 (b) is a rear view for explaining the side unit 240 in the ultrasonic cleaning machine according to the embodiments disclosed by the present invention with the side unit protection part 250 removed.

[0058] Refer toFigures 1 to 4 (b), the ultrasonic cleaner 1 according to the disclosed embodiments of the present invention includes a container unit 100 and a lid unit 300. That is, the ultrasonic cleaner 1 can be configured such that the container unit 100 and the lid unit 300 can be separated or combined with each other.

[0059] Exemplarily, the container unit 100 may include a receiving space (exemplarily, a space formed inside the inner container unit described later) for receiving an object to be cleaned (not shown), and may be open upward. The object to be cleaned may include dental supplies such as dental prostheses or dental orthodontic appliances worn by a user inside the oral cavity. The ultrasonic cleaner 1 according to the disclosed embodiments of the present invention can be manufactured to a size capable of receiving the object to be cleaned, and thus, the ultrasonic cleaner 1 can be miniaturized and manufactured to a size that can be carried.

[0060] The lid unit 300 may be combined to be formed on the upper part of the container unit 100 and may seal the above-mentioned receiving space. The lid unit 300 may be formed in a dome shape, but is not limited to the illustrated example. The structure of the lid unit 300 may have a shape that seals the receiving space of the container unit 100 from the outside while being able to safely protect the object to be cleaned received in the receiving space.

[0061] Moreover, the ultrasonic cleaner 1 according to the disclosed embodiments of the present invention can be sterilized and cleaned by a sterilization unit and a cleaning unit.

[0062] In the ultrasonic cleaner 1 according to the disclosed embodiments of the present invention, the object to be cleaned received in the container unit 100 can be sterilized by sterilization light. For example, the sterilization light may be UV-A light or UV-C light having a relatively small wavelength range. In a state where the object to be cleaned is received in the receiving space of the container unit 100, the sterilization light can be irradiated into the interior of the container unit 100, and the object to be cleaned is sterilized by the sterilization light transmitted through a light transmission medium (for example, air, liquid, etc.), so that it can be kept in a clean state.

[0063] In the ultrasonic cleaning machine 1 according to the embodiments disclosed in the present invention, the object to be cleaned accommodated in the container unit 100 can be cleaned by ultrasonic vibration. Exemplarily, in a state where the object to be cleaned is accommodated in the accommodation space of the container unit 100, the vibration plate that generates ultrasonic waves can vibrate, and the object to be cleaned is cleaned by the vibration energy transmitted through the vibration transmission medium (e.g., liquid, etc.), so that it can be kept in a clean state. More specifically, a cavitation phenomenon that generates bubbles is caused in the vibration transmission medium that receives the vibration energy, and a corresponding physical force is applied to the surface of the object to be cleaned by the physical force generated by the rupture of the generated bubbles, so that the object to be cleaned can be cleaned and kept in a clean state.

[0064] In addition, although the ultrasonic cleaning machine 1 according to the embodiments disclosed in the present invention is described throughout the specification of the present invention, it should be understood that the ultrasonic cleaning machine 1 according to the embodiments disclosed in the present invention is a device capable of simultaneously performing the sterilization process of the object to be cleaned by sterilizing light.

[0065] Hereinafter, a more detailed description will be given of the detailed configuration of the ultrasonic cleaning machine 1 according to the embodiments disclosed in the present invention.

[0066] Refer to Figures 1 to 4 (b) (In particular, refer to Figure 2 ), the container unit 100, as a component of the ultrasonic cleaning machine 1 according to the embodiments disclosed in the present invention, can include various detailed component elements. Exemplarily, the container unit 100 can include outer container units 120 and 150. The outer container units 120 and 150 can form the outer surface of the container unit 100. More specifically, the outer container units 120 and 150 can include a side surface portion 150 that forms the outer peripheral surface of the container unit 100 and a bottom portion 120 that forms a bottom surface at one end of the side surface portion 150.

[0067] The bottom 120 may form a bottom surface for placing the ultrasonic cleaning machine 1 according to the disclosed embodiments of the present invention on the ground. The bottom 120 may have a shape corresponding to the outer peripheral surface of the container unit 100. Exemplarily, when the container unit 100 has a cylindrical structure with an open upper portion, the bottom surface of the bottom 120 may be formed to have a disc structure. And, a buffer unit 110 may be included on the bottom surface of the bottom 120. The buffer unit 110 has a predetermined thickness in the up and down direction (e.g., the direction of gravity) along its outer peripheral surface, and the bottom 120 protrudes downward from the bottom surface. The buffer unit 110 may be formed of a material with high elastic force and high friction, such as rubber material or polyurethane material. At this time, "high elastic force" may mean that the elastic coefficient is relatively larger than other materials, and "high friction" may mean that the friction coefficient (e.g., static friction coefficient) is relatively larger than other materials. Therefore, when the bottom 120 is placed on the ground to support the ultrasonic cleaning machine 1 including the container unit 100, the upper surface of the buffer unit 110 adheres to a part of the bottom surface of the bottom 120, while the lower surface of the buffer unit 110 contacts the ground, thereby having the advantages of being able to buffer the impact applied to the container unit 100 and preventing movement on the placed ground due to external force.

[0068] The side surface part 150 may form the outer peripheral surface of the ultrasonic cleaning machine 1 according to the disclosed embodiments of the present invention, and may form a contour for protecting the object to be cleaned. The side surface part 150 may have a shape communicating in the up and down direction. And, at least one opening part may be formed on at least a part of the outer peripheral surface of the side surface part 150. More specifically, the side surface part 150 may include a first opening part formed on one side and a second opening part formed at a predetermined distance from the first opening part. The input part 230 for opening and closing the ultrasonic cleaning machine 1 according to the disclosed embodiments of the present invention may be arranged at the first opening part of the side surface part 150, and the side unit 240 for supplying external power to the ultrasonic cleaning machine 1 according to the disclosed embodiments of the present invention may be arranged at the second opening part of the side surface part 150.

[0069] And, the side surface part 150 of the outer container units 120, 150 in the container unit 100 may include an outer container unit side receiving groove 151, an outer container unit side protruding rib 152, and an outer container unit side receiving slit 153 on its inner peripheral surface. By means of the outer container unit side receiving groove 151 and the outer container unit side protruding rib 152, the outer container units 120, 150 may be aligned and combined with the substrate bracket 170 and the container - lid coupling part 220 described later. The combination of the outer container units 120, 150, the substrate bracket 170, and the container - lid coupling part 220 will be described later.

[0070] Moreover, at least one sealing unit 125 is formed between the bottom 120 and the side surface 150 of the outer container units 120, 150. The at least one sealing unit 125 seals the gap between the outer circumferential surface of the bottom 120 and the inner circumferential surface of the side surface 150, and may be formed of a waterproof material. The at least one sealing unit 125 is formed to seal between the bottom 120 and the side surface 150, thereby having the advantage of being able to waterproof the components (e.g., power supply unit, first substrate, second substrate, etc.) disposed inside the outer container units 120, 150.

[0071] The ultrasonic cleaner 1 according to the embodiment disclosed in the present invention may include a power supply unit 130 to enable a user to carry and operate without supplying a separate external power source. The power supply unit 130 may supply the power required for the sterilization and / or cleaning operation of the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention and the components for confirming the sterilization operation state and / or the power supply state.

[0072] The power supply unit 130 may be a DC power supply device having a constant potential difference and capable of supplying uniform power to the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention. Exemplarily, the power supply unit 130 may be at least one of known DC power supply devices such as a rechargeable lithium-polymer battery, a dry battery, etc., but is not necessarily limited to the listed examples. The power supply unit 130 may be placed on the upper side of the bottom 120 in the aforementioned outer container units 120, 150. The bottom 120 may serve to stably protect the outer surface of the power supply unit 130 from the external environment (e.g., physical shock, chemical influence). For example, the upper part of the bottom 120 may be formed in a rib structure for supporting at least a part of the outer circumferential surface of the power supply unit 130.

[0073] Moreover, the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention may further include a power supply unit fixing part 140. The power supply unit fixing part 140 is formed on the upper part of the power supply unit 130 and can prevent the power supply unit 130 from detaching from the bottom 120.

[0074] In the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention, the container unit may include an inner container unit 210. The inner container unit 210 may substantially form a receiving space inside thereof capable of receiving an object to be cleaned. The inner container unit 210 may have an upwardly open shape and may generally have a shape corresponding to the above-mentioned outer container units 120 and 150. For example, when the outer container units 120 and 150 have an upwardly open cylindrical shape, the inner container unit 210 may also have an upwardly open cylindrical shape. The inner container unit 210 may be arranged to be received inside the outer container units 120 and 150. In order to stably receive the inner container unit 210 in the outer container units 120 and 150, the outer diameter of the inner container unit 210 may be formed to be smaller than the inner diameter of the outer container units 120 and 150, and the height of the inner container unit 210 may be formed to be smaller than the height of the outer container units 120 and 150, and the height of the inner container unit 210 may be formed to be smaller than the height of the side surface part 150 of the outer container units 120 and 150.

[0075] Moreover, the inner container unit 210 may be formed of a material for cleanly storing the object to be cleaned. More specifically, the outer container units 120 and 150 and the inner container unit 210 may be formed of different materials. Exemplarily, the material of the outer container units 120 and 150 may be at least one of known plastic resin materials including polycarbonate (PC), acrylonitrile-butadiene-styrene copolymers (ABS), or a mixture thereof, and the material of the inner container unit 210 may be a stainless steel material with strong corrosion resistance and pollution resistance and capable of applying ultrasonic cleaning. Therefore, the outer container units 120 and 150 are formed of a lightweight material, so that the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention can be lightened to improve the portability of the user, and the inner container unit 210 can cleanly store and manage the object to be cleaned.

[0076] Hereinafter, the ultrasonic vibration modules 160, 170, and 180, which are a component of the container unit 100, will be described.

[0077] Refer to Figures 1 to 4 (In particular, refer to Figure 2) According to an embodiment disclosed by the present invention, the container unit 100 of the ultrasonic cleaner 1 may include ultrasonic vibration modules 160, 170, and 180. The ultrasonic vibration modules 160, 170, and 180 may provide ultrasonic vibration to an object to be cleaned housed in the inner container unit 210. More specifically, the ultrasonic vibration modules 160, 170, and 180 may ultrasonically clean the surface of the object to be cleaned by vibrating a medium filled in a housing space (a space formed inside the inner container unit).

[0078] The ultrasonic vibration modules 160, 170, and 180 may include a vibration plate 180, a first substrate 160, and a substrate bracket 170. Exemplarily, the first substrate 160 may be disposed at the lower part of the ultrasonic vibration modules 160, 170, and 180, which may control the vibration plate 180 and supply power to the vibration plate 180 for causing the vibration plate 180 to supply ultrasonic vibration to the medium. The substrate bracket 170 may function to fix the first substrate 160 such that the first substrate 160 is positioned inside the container unit 100. The vibration plate 180 may be attached to the outside of the inner container unit 210 (more specifically, the outside of the lower surface of the inner container unit 210) and / or in contact with the outside of the inner container unit 210. The vibration plate 180 of the ultrasonic vibration modules 160, 170, and 180 transfers vibration energy to the inner container unit 210, and by vibrating the medium housed inside the inner container unit 210, physical force generated by the bursting of bubbles generated by cavitation can be applied to the surface of the object to be cleaned, and foreign matter attached to the surface of the object to be cleaned can be removed from the object to be cleaned by the vibration energy.

[0079] Moreover, the substrate bracket 170 for positioning the first substrate 160 in the container unit 100 may include a ring portion 171. The ring portion 171 is formed in a ring shape to correspond to the inner peripheral surface of the side surface portion 150 of the outer container units 120, 150 in the container unit 100. That is, the ring portion 171 may be formed in a shape that can be easily housed inside the side surface portion 150 of the outer container units 120, 150. The outer peripheral surface of the ring portion 171 may be supported by a part of the inner peripheral surface of the side surface portion 150.

[0080] Further, the substrate holder 170 may include a first protrusion 172 on the side of the substrate holder. Exemplarily, the first protrusion 172 on the side of the substrate holder may be formed by protruding downward from one side of the ring portion 171 by a predetermined first protrusion height. The first protrusion 172 on the side of the substrate holder may be fastened to the outer container units 120 and 150 in the container unit 100. That is, each of the bottom 120 and the side surface 150 of the outer container units 120 and 150 may include a fastening hole (not shown) for coupling with the first protrusion 172 on the side of the substrate holder. At least a part of the first protrusion 172 on the side of the substrate holder is fastened together with the bottom 120 and the side surface 150 by a fastening member (e.g., including at least one of a bolt and a rivet), whereby the first substrate 160 may be positioned inside the container unit 100.

[0081] More specifically, the first protrusion 172 on the side of the substrate holder may include a plurality of first protrusion units 172a on the side of the substrate holder. Each of the plurality of first protrusion units 172a on the side of the substrate holder may be formed in a pin shape to be coupled with the outer container units 120 and 150. And, with reference to the center in the radial direction of the substrate holder 170, each of the plurality of first protrusion units 172a on the side of the substrate holder may be formed at a predetermined first angular pitch. Exemplarily, when the plurality of first protrusion units 172a on the side of the substrate holder are provided as three, the plurality of first protrusion units 172a on the side of the substrate holder may be formed to be spaced apart from each other at an interval of 120°. As described above, since the plurality of first protrusion units 172a on the side of the substrate holder are formed at a predetermined first angular pitch, there are advantages of being able to prevent the substrate holder 170 from tilting to one side and being able to stably support the first substrate 160 and the like.

[0082] In addition, the first substrate 160 may include: a first substrate body 161; and a substrate holder receiving portion 162 on the side of the first substrate, which is locally recessed inwardly in a part of the outer peripheral surface of the first substrate body 161. The plurality of first protrusion units 172a of the first protrusion 172 on the side of the substrate holder may penetrate the substrate holder receiving portion 162 on the side of the first substrate from the upper part to the lower part. At this time, the width of each of the plurality of first protrusion units 172a on the side of the substrate holder may be formed in a tapered shape that gradually decreases as it protrudes downward from the side of the ring portion 171. As the width of each of the plurality of first protrusion units 172a on the side of the substrate holder is formed in a tapered shape, the substrate holder 170 may more easily fix the first substrate 160.

[0083] According to the situation, the width of the outer periphery of the recess of the first substrate side substrate support receiving portion 162 may correspond to one of the plurality of substrate support side first protruding units 172a. More specifically, the plurality of substrate support side first protruding units 172a may have a first tapered width w1 on the ring portion 171 side, and while extending in the lower direction, the width may be reduced to a second tapered width w2. At this time, the width of the outer periphery of the recess of the first substrate side substrate support receiving portion 162 may be formed to be equal to or less than the average of the first tapered width w1 and the second tapered width w2. Accordingly, the first substrate 160 may be positioned within the container unit 100 by the substrate support 170, and has the advantage of improving the stability of the ultrasonic cleaning machine 1 according to the embodiments disclosed in the present invention.

[0084] In addition, the substrate support 170 may further include substrate support side second protrusions 173 and 175. The substrate support side second protrusions 173 and 175 may be formed to protrude upward from the other side of the ring portion 171 by a predetermined second protrusion height. Exemplarily, the substrate support side second protrusions 173 and 175 may start to protrude upward from the side opposite to the side where the above-described substrate support side first protrusion 172 protrudes from the ring portion 171 (for example, the upper side of the ring portion 171). The substrate support side second protrusions 173 and 175 may be aligned with a part of the inner peripheral surface of the side surface portion 150 of the outer container units 120 and 150 in the container unit 100. Accordingly, the substrate support 170 may firmly couple the first substrate 160 and the outer container units 120 and 150.

[0085] More specifically, the substrate support side second protrusions 173 and 175 may include at least one first type substrate support side second protruding unit 173 and at least one second type substrate support side second protruding unit 175. The first type substrate support side second protruding unit 173 may form an annular structure and may include a substrate support side second protruding receiving groove. And, the second type substrate support side second protruding unit 175 may form a concavo-convex structure in the vertical direction. Exemplarily, the second type substrate support side second protruding unit 175 may include a pair of guiding protrusions 175a, and between the pair of guiding protrusions 175a, there may be included a substrate support side second protruding portion receiving slit 175b. Accordingly, the container-lid coupling portion 220 described later can be easily and firmly coupled.

[0086] Hereinafter, the container-lid coupling portion 220 that couples the lid unit 300 and the container unit 100 will be described.

[0087] As a component of the ultrasonic cleaner 1 according to an embodiment disclosed in the present invention, the container unit 100 may further include a container - lid coupling part 220. The container - lid coupling part 220 may be positioned inside the container unit 100 by means of the substrate support 170. The container - lid coupling part 220 may be formed in an annular shape, and a part of the container - lid coupling part 220 may be disposed on the upper part of the side surface 150 of the outer container units 120, 150.

[0088] More specifically, the container - lid coupling part 220 may include an outer - container placement part 221, which is formed to protrude a predetermined thickness from a container - lid coupling - part body (not shown) and has an outer diameter corresponding to the outer diameters of the outer container units 120, 150. That is, the outer - container placement part 221 may be located on the upper part of the side surface 150 of the outer container units 120, 150, and the outer - container placement part 221 may be coupled to be supported by the upper side of the side surface 150. Accordingly, it is possible to prevent the container - lid coupling part 220 from being excessively inserted into the inner parts of the outer container units 120, 150.

[0089] Moreover, the container - lid coupling part 220 may include an outer - container coupling part 222. The outer - container coupling part 222 may form the lower part of the container - lid coupling - part body and is formed below the outer - container placement part 221 with the outer - container placement part 221 as a reference. The outer peripheral surface of the outer - container coupling part 222 may be protected from the outside by the side surface 150 of the outer container units 120, 150.

[0090] In addition, the outer - container coupling part 222 may include a configuration for coupling with the side surface 150 of the outer container units 120, 150 and the substrate support 170.

[0091] Exemplarily, the outer - container coupling part 222 may include a first protrusion unit 223 on the container - lid coupling - part side. The first protrusion unit 223 on the container - lid coupling - part side may be formed to extend horizontally in a shape corresponding to a second protrusion - part receiving groove on the substrate - support side in the substrate support 170 and may protrude a predetermined thickness in the radial direction. More specifically, the first protrusion unit 223 on the container - lid coupling - part side may receive and be coupled to a part of the first - type second protrusion unit on the substrate - support side among the second protrusion parts 173, 175 on the substrate - support side of the above - mentioned substrate support 170. The first protrusion unit 223 on the container - lid coupling - part side may protrude in a dash (-) shape.

[0092] As another example, the outer container coupling part 222 may include a container-cover coupling part side rib receiving unit 224. The container-cover coupling part side rib receiving unit 224 may form an opening in the vertical direction to have a shape corresponding to the outer container unit side protruding rib 152 which is a component of the side surface 150 of the outer container units 120 and 150. The container-cover coupling part side rib receiving unit 224 may receive the outer container unit side protruding rib 152 in the vertical direction.

[0093] As yet another example, the outer container coupling part 222 may include a container-cover coupling part side second protruding unit 225. The container-cover coupling part side second protruding unit 225 is formed to extend in the vertical direction in a shape corresponding to the substrate holder side second protruding part receiving slit 175b in the substrate holder 170, and protrudes in the radial direction with a predetermined thickness. More specifically, the container-cover coupling part side second protruding unit 225 is guided by a pair of guiding protruding parts 175a of the second type of substrate holder side second protruding unit 175 among the substrate holder side second protruding parts 173 and 175 of the above-mentioned substrate holder 170, and thus is received and coupled to the substrate holder side second protruding part receiving slit 175b. The container-cover coupling part side second protruding unit 225 may protrude in a column shape.

[0094] Hereinafter, the coupling relationship among the substrate holder 170, the container-cover coupling part 220, and the outer container units 120 and 150 will be described.

[0095] In the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention, the side surface 150 of the outer container units 120 and 150 may further include an outer container unit side receiving groove 151 on its inner peripheral surface. For example, the outer container unit side receiving groove 151 may be formed by being recessed by a predetermined depth in the radial direction on the inner peripheral surface of the side surface 150 of the outer container units 120 and 150. The shape of the outer container unit side receiving groove 151 may correspond to the container-cover coupling part side first protruding unit 223 of the container-cover coupling part 220.

[0096] More specifically, the second protruding housing groove on the substrate holder side of the first type of substrate holder 170 of the substrate holder 170 can be aligned with the housing groove 151 on the outer container unit side, and the first protruding unit 223 on the container-lid coupling part side can be simultaneously housed in the second protruding housing groove on the substrate holder side and the housing groove 151 on the outer container unit side, thereby restricting the movement in the vertical direction. More specifically, the first protruding units 223 on the container-lid coupling part side can be arranged in two rows, at least one of the first protruding units 223 on the container-lid coupling part side is housed in the second protruding housing groove on the substrate holder side of the substrate holder 170, and the remaining one of the first protruding units 223 on the container-lid coupling part side is housed in the housing groove 151 on the outer container unit side, thereby restricting the movement in the vertical direction. Therefore, the container-lid coupling part 220 remains in a state of being coupled to the substrate holder 170 and the outer container units 120 and 150, thereby enabling a stable assembled structure to be formed.

[0097] Moreover, in the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention, the side surface 150 of the outer container units 120 and 150 may further include an outer container unit side protruding rib 152 on its inner circumferential surface. Exemplarily, the outer container unit side protruding rib 152 may protrude a predetermined depth in a direction toward the central axis on the inner circumferential surface of the side surface 150 of the outer container units 120 and 150. The shape of the outer container unit side protruding rib 152 may correspond to the rib housing unit 224 on the container-lid coupling part side of the container-lid coupling part 220.

[0098] More specifically, the rib housing unit 174 on the substrate holder side of the substrate holder 170 can be aligned with the outer container unit side protruding rib 152, which is formed by protruding a predetermined thickness inward on the inner circumferential surface of the side surface 150 of the outer container units 120 and 150. The outer container unit side protruding rib 152 can be housed in the rib housing unit 174 on the substrate holder side and the rib housing unit 224 on the container-lid coupling part side, thereby restricting the rotation of the outer container unit side protruding rib 152 in one direction. Therefore, the container-lid coupling part 220 remains in a state of being coupled to the substrate holder 170 and the outer container units 120 and 150, and thus a stable assembled structure can be formed.

[0099] Moreover, in the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention, the side surface 150 of the outer container units 120 and 150 may further include an outer container unit side housing slit 153 on its inner circumferential surface. For example, the outer container unit side housing slit 153 may be formed by being recessed a predetermined depth in the radial direction on the inner circumferential surface of the side surface 150 of the outer container units 120 and 150. The shape of the outer container unit side housing slit 153 may correspond to the second protruding unit 225 on the container-lid coupling part side of the container-lid coupling part 220.

[0100] More specifically, the substrate holder side second protrusion receiving slit 175b of the second type substrate holder side second protrusion unit 175 of the substrate holder 170 is aligned with the outer container unit side receiving slit 153. The outer container unit side receiving slit 153 is formed by being recessed by a predetermined depth in the radial direction on the inner circumferential surface of the side surface portion 150 of the outer container units 120 and 150. And the container - lid coupling part side second protrusion unit 225 is received in the substrate holder side second protrusion receiving slit 175b and the outer container unit side receiving slit 153, thereby restricting rotation in one direction. Therefore, the container - lid coupling part 220 is maintained in a state of being coupled to the substrate holder 170 and the outer container units 120 and 150, and thus a stable assembled structure can be formed.

[0101] As described above, the relative movement of the outer container units 120 and 150, the substrate holder 170, and the container - lid coupling part 220 is structurally restricted. Therefore, the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention has the advantage of being able to form a firm assembled structure.

[0102] Hereinafter, the detailed configuration of the lid unit 300 and the coupling relationship between the container - lid coupling part 220 and the lid unit 300 will be described.

[0103] Figure 5 It is a view showing the shape of turning over the lid unit 300 which is a component of the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention. Figure 6 It is a perspective view for explaining the container unit 100 which is a component of the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention. Figure 7 It is a front view for explaining the container unit 100 which is a component of the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention. Figure 8 It is a perspective view for explaining the process of coupling the container unit 100 and the lid unit 300 in the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention.

[0104] Refer to the whole Figures 1 to 8, in the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention, the container-lid coupling part 220 may further include a lid coupling part 226. The lid coupling part 226 may form the upper part of the container-lid coupling part main body and may be formed above the outer container placement part 221 with respect to the outer container placement part 221 as a reference. In order to be coupled to the lid unit 300 described later, the lid coupling part 226 may include a spiral-shaped lid guide protrusion 227 formed by protruding a predetermined thickness along the radial direction from the outer circumferential surface of the container-lid coupling part main body. Due to the spiral shape of the lid guide protrusion 227, the lid unit 300 may rotate relatively on the outer circumferential surface of the container-lid coupling part 220 and be coupled to the container unit 100, and it may prevent the cleaning object and / or the medium for ultrasonic vibration accommodated in the inner container unit 210 from escaping to the outside.

[0105] More specifically, each of the lid guide protrusions 227 may be formed to protrude at equal intervals within a range of 30° to 90° with respect to the center in the radial direction of the container-lid coupling part main body. For example, the lid coupling part 226 may include four spiral-shaped lid guide protrusions 227 having a predetermined spiral angle θ, and each lid guide protrusion 227 may be formed to have a protruding angle Φ of 90°. As another example, the lid coupling part 226 may include six spiral-shaped lid guide protrusions 227 having a predetermined spiral angle θ, and each lid guide protrusion 227 may be formed to have a protruding angle Φ of 60°.

[0106] In addition, the lid unit 300 coupled to the container unit 100 may include a lid unit main body 310. The lid unit main body 310 may cover the outer circumferential surface of the container-lid coupling part 220, thereby protecting the cleaning object etc. accommodated inside the container unit 100 from the external environment. The lid unit main body 310 may include a lid unit side surface part 311, a lid unit upper part 312, and a lid unit opening part 313. The lid unit side surface part 311 may constitute the side surface of the lid unit main body 310, and the lid unit upper part 312 may extend from the lid unit side surface part 311 and constitute the upper surface of the lid unit main body 310. And, the lid unit opening part 313 is formed in at least a part of the lid unit upper part 312, and by the operation of the second substrate 190 in which the sterilization modules 201, 202, 203 are built-in, a lid unit lens part 320 capable of confirming the state of the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention may be arranged.

[0107] And, the lid unit 300 may include a lid unit main body-lens coupling part 330, and the lid unit main body-lens coupling part 330 may include a lid unit main body-lens coupling groove 331 in its upper part. Through the lid unit main body-lens coupling groove 331, a state in which the lid unit main body 310 and the lid unit lens part 320 are stably coupled can be maintained.

[0108] In addition, the lid unit 300 may include a sealing lid 340. When the lid unit 300 is coupled to the container unit 100, the sealing lid 340 may prevent the contents (e.g., a medium for ultrasonically cleaning an object to be cleaned) accommodated inside the container unit 100 from escaping to the outside. In a state where the lid unit 300 is coupled to the container unit 100, the sealing lid 340 may contact the upper portion of the container-lid coupling part 220 and may seal between the container-lid coupling part 220 and the lid unit 300. The sealing lid 340 may be formed of at least one of highly elastic materials such as rubber material and polyurethane material.

[0109] In addition, the lid unit body 310 of the lid unit 300 may include lid protrusions 314 on its inner circumferential surface. The lid protrusions 314 may be formed to protrude a predetermined thickness in an inward direction from the inner circumferential surface of the lid unit (more specifically, the lid unit body 310), and may be formed in a number and shape corresponding to those of the lid guiding protrusions 227 described above. For example, when the lid coupling part 226 includes four lid guiding protrusions 227 having a spiral shape, the lid protrusions 314 may also be formed in four in a spiral shape.

[0110] The lid unit 300 rotates in one direction in a manner corresponding to the angular range (e.g., protruding angle) in which the plurality of lid guiding protrusions 227 protrude, so that the accommodation space can be opened or closed. At this time, due to the number and protruding angle Φ of the lid guiding protrusions 227, even if the lid unit 300 rotates by less than 90°, the accommodation space can be easily opened or closed. Accordingly, a user of the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention can open and close the accommodation space even by rotating the lid unit 300 relative to the container unit 100 by a small angle, and thus has an advantage of improving the usability of the ultrasonic cleaner 1.

[0111] Hereinafter, an operation for sterilizing an object to be cleaned using a sterilization module provided in the second substrate 190 and informing the user of the state of the ultrasonic cleaner 1 will be described.

[0112] Figure 9 FIG. is a diagram for explaining a sterilization module provided in the second substrate 190, which is a configuration of the container unit 100 in the ultrasonic cleaner 1 according to the embodiment disclosed in the present invention.

[0113] Overall reference Figures 1 to 9 (In particular, Figure 2 and Figure 9) According to an embodiment disclosed by the present invention, the ultrasonic cleaner 1 may include a sterilization module. The sterilization module may irradiate light within a predetermined wavelength range onto the object to be cleaned accommodated in the accommodation space. At this time, the light may include sterilization light (e.g., UV-C light) for removing bacteria on the surface of the object to be cleaned. Additionally, the sterilization module may receive power for generating light through a second substrate 190 disposed below it. The sterilization light generated from the sterilization module may be diffused into the inner space of the inner container unit 210 through the sterilization module lens 200, and may sterilize the object to be cleaned stored in the inner container unit 210.

[0114] In order to transmit the light generated from the sterilization module 200 to the inside of the inner container unit 210, the inner container unit 210 may include a light transmission part 211 that is open with a predetermined transmission radius or formed of a light-transmissive material at its central part. Exemplarily, when an opening is formed in the light transmission part 211, at least a part of the sterilization module may be formed to protrude locally from the lower part of the inner container unit 210, and the protruding part of the sterilization module and the inner container unit 210 may be sealed. As another example, when the light transmission part 211 is formed of a light-transmissive lens, the light transmission part 211 may be formed of a transparent or translucent material and guide the light generated by the sterilization module 200 to the inside of the inner container unit 210.

[0115] More specifically, the sterilization module may include a first light unit 201, a second light unit 202, and a third light unit 203. The first light unit 201 may transmit first light within a first wavelength range to the inside of the inner container unit 210 through the light transmission part 211. And, the second light unit 202 may be formed on one side of the first light unit 201, and may transmit second light within a second wavelength range different from the first wavelength range to the inside of the inner container unit 210 through the light transmission part 211. And, the third light unit 203 may be formed on one side of the first light unit 201, and may transmit third light within a third wavelength range different from the first wavelength range and the second wavelength range to the inside of the inner container unit 210 through the light transmission part 211.

[0116] Exemplarily, the first light generated by the first light unit 201 can perform sterilization on the object to be cleaned, and the second light generated by the second light unit 202 serves to inform the user whether the sterilization of the first unit 201 is performed by the first light, and the third light generated by the third light unit 203 can serve to inform the user of the operation state of the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention. That is, the first wavelength range of the first light generated by the first light unit 201 can be a wavelength range in the ultraviolet region, and the first light can be sterilization light. However, the first light in the ultraviolet region cannot be recognized by the user's naked eyes. Therefore, for the safety of the user, it is necessary to visually notify the user whether the sterilization by the first light of the first light unit 201 is performed. Therefore, the second wavelength range of the second light generated by the second light unit 202 and the third wavelength range of the third light generated by the third light unit 203 can be wavelength ranges in the visible light region.

[0117] In particular, the second light unit 202 can be linked with the first light unit 201 to guide the user whether to sterilize the object to be cleaned through the first light unit 201. Therefore, the second light unit 202 can operate together according to the operation of the first light unit 201. Exemplarily, if the sterilization light is irradiated inside the inner container unit 210 by the first light unit 201, the second light unit 202 also operates to irradiate the second light inside the inner container unit 210, so that the user can easily recognize whether the sterilization of the object to be cleaned is performed through the cover unit lens part 320. At this time, the second light can be blue light, and the user can easily recognize the color corresponding to the second light visually through the cover unit lens part 320, so it has the advantage of preventing the risk of accidents to the user.

[0118] In addition, a pair of second light units 202, 202a, 202b can be arranged oppositely with the first light unit 201 as the center, and a pair of third light units 203, 203a, 203b can be arranged oppositely with the first light unit 201 as the center and are formed at intervals from the second light units 202, 202a, 202b. More specifically, the second light units 202, 202a, 202b and the third light units 203, 203a, 203b can be alternately arranged along an angular direction with the first light unit 201 as the center. Accordingly, the second light and the third light generated from the second light units 202, 202a, 202b and the third light units 203, 203a, 203b will not deflect to one side, and the user can easily recognize them through the cover unit lens part 320.

[0119] The third light unit 203 may be operable to guide a state different from that of the second light unit 202 to the user. Exemplarily, the third light unit 203 may display the state of the power supply unit 130 described above. In the case where the power supply unit 130 is in a charging state, a dimming operation may be performed, and in the case where the power supply unit 130 has completed charging, the power supply unit 130 may perform an on operation. Accordingly, there is an advantage that the user can easily identify the charging state of the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention.

[0120] Hereinafter, a side unit 240, which is a configuration of the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention, will be described.

[0121] Refer to the whole Figures 1 to 9 (In particular, Figure 2 and Figure 4 ), the container unit 100 of the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention may further include a side unit 240. The side unit 240 includes: a charging terminal 241 that receives an external power source and charges the power supply unit 130 built inside the outer container units 120 and 150; and a status indicator 242 formed on one side of the charging terminal 241 and displaying the (charging) state of the power supply unit 130. The status indicator 242 may display the state of the power supply unit 130. In the case where the power supply unit 130 is in a charging state, a dimming operation may be performed, and in the case where the power supply unit 130 has ended charging, an on operation may be performed. Accordingly, there is an advantage that the user can easily identify the charging state of the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention.

[0122] In addition, a side unit cover 250 made of rubber, including a side unit cover main body 251, a side unit cover handle part 252, and a charging terminal protection part 253 that protects the charging terminal 241, may be coupled to a side unit cover coupling part 243 in the side unit 240. At this time, after the user flips the side unit cover 250 to open the side unit 240, the power supply unit 130 of the ultrasonic cleaner 1 is charged by connecting a charging cable to the charging terminal 241. Therefore, the user can easily confirm the status indicator 242 formed on one side of the charging terminal 241 and can easily identify the charging state of the power supply unit 130.

[0123] Also, the status indicator 242 can be linked with the third light unit 203 so that they can operate together according to the operation of the third light unit 203. The third light unit 203 and the status indicator 242 operate together, thus having the following advantages: Even if the user observes the ultrasonic cleaner 1 at a certain position on the side or the upper surface of the ultrasonic cleaner 1, it is possible to easily confirm the charging status of the power supply unit 130. The operation of the status indicator 242 can correspond to the operation of the above-mentioned third light unit 203.

[0124] In some embodiments, the status indicator 242 can not only indicate the charging status of the power supply unit 130, but also indicate the cleaning operation and / or the sterilization operation of the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention. The status indicator 242 can be linked with at least one of the first light unit 201, the second light unit 202, and the third light unit 203, so that the status indicator 242 can operate together according to their operations. Exemplarily, when the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention performs a cleaning operation, the status indicator 242 can operate by lighting a blue light. As another example, when the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention performs a sterilization operation, the status indicator 242 can operate by lighting a purple light. As yet another example, when the ultrasonic cleaner 1 according to the embodiments disclosed in the present invention is charging, the status indicator 242 can operate by lighting in a different color, or the blue light or the purple light can perform a flashing operation. As described above, the present invention has the following advantages: The user can easily confirm the overall state of the ultrasonic cleaner 1 from the side through the status indicator 242.

[0125] Also, the side unit 240 can further include a status indicator protection lens 244. The status indicator protection lens 244 can be combined and formed on the inner side of the side surface 150 of the above-mentioned outer container units 120 and 150.
