  By the way, a cleaning solution diluted with water is often used. Therefore, the washing liquid is measured with a measuring cup so that the washing liquid is diluted to a predetermined concentration, and water is added thereto to generate a diluted liquid. However, such an operation has a problem that operations such as preparation of a measuring cup, measurement of a cleaning liquid, and cleaning of the measuring cup after use become complicated. The present invention has been made to solve the above problem, and has as its object to provide a tray for an ultrasonic cleaner that can easily generate a diluent of a cleaning liquid having an appropriate concentration.

  The present invention is a tray accommodated in a bathtub of an ultrasonic cleaner, comprising: a plate-shaped tray main body; and a measuring unit provided on the tray main body and capable of storing a predetermined amount of a cleaning liquid. .

  According to this configuration, since the measuring section is provided, if the cleaning liquid is supplied until the measuring section is full, the required amount of cleaning liquid for cleaning can be accumulated, and a predetermined amount of water can be added thereto. If this is the case, it is possible to generate a diluent of a cleaning liquid suitable for cleaning. Therefore, there is no need to measure the cleaning liquid with a measuring cup or the like, and an appropriate diluting liquid can be easily generated. Therefore, complicated operations such as preparation of the measuring cup, measurement of the cleaning liquid, and cleaning of the measuring cup are not required, and the cleaning operation by the ultrasonic cleaner can be efficiently performed.

  In the tray, a plurality of through holes may be formed in the tray main body in a region where the measuring unit is not disposed.

  Accordingly, the lower surface and the upper surface of the tray main body communicate with each other through the through hole, so that ultrasonic vibration can be transmitted to the object to be cleaned on the tray main body via the diluent passing through the through hole. Therefore, the object to be cleaned can be effectively vibrated, and the cleaning effect can be enhanced.

  In the tray, the area where the weighing unit is not arranged can be formed in a mesh shape.

  This allows the lower surface and the upper surface of the tray body to communicate with each other in a larger area, so that the object to be cleaned can be more effectively vibrated, and the cleaning effect can be enhanced.

  In the tray, the weighing unit may be arranged near a center of the tray body.

  For example, if the object to be cleaned is a denture, the denture is formed in a U-shape. Therefore, if the weighing unit is arranged near the center of the tray main body, the U-shaped denture surrounds the weighing unit. Can be arranged. As a result, vibration can be effectively applied to the denture.

  In the tray, the area of the measuring section may be, for example, 50% or less of the area of the tray body.

  In the tray, the weighing unit may include a bottom wall portion and a peripheral wall portion extending from a peripheral edge of the bottom wall portion, wherein the peripheral wall portion is configured to protrude from an upper surface of the tray main body. Can be.

  In the above tray, the lower surface of the bottom wall portion may be configured to be located lower than the lower surface of the tray main body.

  Thereby, since the internal space of the weighing unit is formed below the upper surface of the tray main body, for example, if the capacity of the weighing unit is the same as when the bottom wall is on the tray main body, The height of the peripheral wall protruding from the upper surface can be reduced. Therefore, it is possible to prevent the peripheral wall from obstructing the object to be cleaned disposed on the tray body, and as a result, it is possible to prevent the object to be cleaned from coming out of the cleaning liquid.

  In the tray, at least one projection may be formed on the lower surface of the tray body to form a gap between the lower surface and the bottom surface of the bathtub, and the lower surface of the bottom wall portion may be formed as follows. The tray may be configured to be located between a lower end of the protrusion and a lower surface of the tray body.

  According to this configuration, the contact area between the tray main body and the bathtub can be reduced by the projection, so that transmission of the ultrasonic vibration to the tray main body can be suppressed. In addition, the protrusion can prevent the lower surface of the measuring section from contacting the bathtub. As a result, the vibrations of the tray main body and the measuring section are transmitted to the vibrator of the cleaning device, and the vibrator can be prevented from being damaged.

  ADVANTAGE OF THE INVENTION According to this invention, the diluent of the washing | cleaning liquid of a suitable density | concentration can be produced easily.

Next, the tray 2 according to the present embodiment will be described with reference to FIGS. 3 is a perspective view of the tray, FIG. 4 is a plan view of FIG. 3, FIG. 5 is a perspective view of the tray viewed from below, and FIG. 6 is a sectional view taken along line AA of FIG.

  As shown in FIGS. 3 to 6, the tray 2 is housed in a bathtub 12 of the ultrasonic cleaner 1, and has a plate-shaped tray body 21 and a weighing device provided near the center of the tray body 21. A tray 22, a handle 23 attached to the tray body 21, and a plurality of protrusions 24 provided on the lower surface of the tray body 21. These are made of a resin material such as polycarbonate, ABS, PP, or stainless steel. It is formed integrally.

  The tray body 21 is formed in a semicircular shape according to the shape of the bathtub 12 of the ultrasonic cleaner 1. That is, it has a contour connecting the straight part 211 and the arc part 212, and the peripheral part is slightly curved upward. The above-mentioned handle 23 is formed in a U-shape extending upward from the vicinity of the center of the arc portion 212 of the tray body 21. That is, both ends of the handle 23 are connected to the arc portion 212.

  The weighing unit 22 includes a circular bottom wall 221 and a peripheral wall 222 extending upward from a peripheral edge of the bottom wall 221. In the space surrounded by the bottom wall 221 and the peripheral wall 222, A fixed amount of washing liquid can be stored. For example, the measuring unit 22 can store 5 ml of the cleaning liquid. As shown in FIG. 6, the lower surface of the bottom wall portion 221 is located below the lower surface of the tray body 21, and the peripheral wall portion 222 protrudes upward from the upper surface of the tray body 21. The height at which the peripheral wall portion 222 of the measuring section 22 projects from the upper surface of the tray main body 21 can be, for example, 5 to 20 mm.

  In the tray main body 21, the area other than the area where the measuring section 22 is provided constitutes a mesh area 213 formed in a mesh shape. That is, in the mesh area 213, a plurality of rectangular through holes communicating the upper surface side and the lower surface side of the tray main body 21 are formed. In addition, the proportion occupied by the measuring portion 22 in the area of the tray body 21 in plan view is preferably 50% or less, more preferably 10 to 40%, and particularly preferably 25 to 35%. preferable.

<3. Cleaning method>
Next, a method for cleaning a denture using the ultrasonic cleaner 1 and the tray 2 configured as described above will be described with reference to FIG.

  First, after moving the cover 13 to the open position, the tray 2 is arranged in the bathtub 12 of the ultrasonic cleaner 1 such that the protrusion 24 contacts the bottom surface 121. Subsequently, the cleaning liquid is supplied to the measuring section 22. At this time, the supply is performed so that the entire internal space of the measuring section 22 is filled with the cleaning liquid. Thereby, 5 ml of the washing liquid is stored in the measuring section 22.

  Next, water is supplied to the bathtub 12. Water is supplied to the mark on the side wall surface 122 of the bathtub 12. Thereby, the cleaning liquid contained in the measuring section 22 is diluted to an appropriate concentration, and a diluting liquid is generated. Subsequently, a denture (not shown) to be cleaned is arranged on the tray 2. The denture may be a general denture or a partial denture. Further, one or both of the upper denture and the lower denture may be arranged. As shown in FIG. 7, when both dentures 500 are arranged, they are arranged so as to be stacked on the tray 2. In addition, after supplying the cleaning liquid to the measuring unit 22, the dentures may be arranged in the bathtub 12, and thereafter, water may be supplied to the bathtub 12. In this case, the concentration of the diluent changes depending on the size of the denture, etc., but since the volume of the denture is smaller than the volume of the bathtub 12, the concentration does not change so much as to affect the cleaning performance.

  Subsequently, when the cover 13 is closed and the button 111 is pressed, an ultrasonic wave is generated from the vibrator for a predetermined time, and this vibrates the denture 500 via the wall surface of the bathtub 12 and the diluent. As a result, the cleaning effect of the diluting solution is also assisted, and the denture stain is removed. Thereafter, when the vibration stops, the cover 13 is opened and the denture 500 and the tray 2 are taken out.

<4. Features>
As described above, according to the present embodiment, the following effects can be obtained.
(1) Since the measuring section 22 is provided on the tray 2, if the cleaning liquid is supplied until the measuring section 22 is full, the required amount of cleaning liquid for cleaning can be stored. Then, if a predetermined amount of water is added to the bathtub 12, a diluent of a cleaning liquid suitable for cleaning can be generated. Therefore, there is no need to measure the cleaning liquid with a measuring cup or the like, and an appropriate diluting liquid can be easily generated. Therefore, complicated operations such as preparation of the measuring cup, measurement of the cleaning liquid, and cleaning of the measuring cup are not required, and the cleaning operation by the ultrasonic cleaner can be efficiently performed.

(2) Since the mesh area 213 is formed in the tray body 21 so as to surround the measuring section 22, the lower surface and the upper surface of the tray body 21 communicate with each other through the through holes of the mesh area 213. Therefore, the ultrasonic vibration can be transmitted to the denture on the tray main body 21 via the diluent passing through the through hole. Therefore, more vibration can be applied to the denture, and the cleaning effect can be enhanced.

(3) Since the bottom wall 221 of the weighing unit 22 is formed so as to be located below the lower surface of the tray main body 21, a part of the internal space of the weighing unit 22 is lower than the upper surface of the tray main body 21. Is formed. On the other hand, for example, as compared with the case where the bottom wall portion 221 is on the tray main body 21, if the capacity of the measuring portion 22 is the same, the height of the peripheral wall portion 222 protruding from the upper surface of the tray main body 21 is reduced. can do. Therefore, it is possible to prevent the peripheral wall portion 222 from interfering with the denture arranged on the tray main body 21, and as a result, more dentures can be accommodated in the bathtub 12.

(4) The contact area between the tray main body 21 and the bathtub 12 can be reduced by the projections 24 formed on the lower surface of the tray main body 21, so that transmission of ultrasonic vibration to the tray main body 21 is suppressed. Can be. In addition, the protrusion 24 can prevent the lower surface of the measuring unit 22 from contacting the bathtub 12. As a result, the vibration of the tray main body 21 and the weighing unit 22 is transmitted to the vibrator, and the vibrator can be prevented from being damaged.

(5) Since the measuring section 22 is provided near the center of the tray body 21 and the mesh area 213 is provided around the measuring section 22, a high cleaning effect can be obtained. In particular, in the present embodiment, in order to clean the U-shaped denture, if the mesh region 213 is arranged in a portion corresponding to the tooth, the vibration is easily transmitted from the lower surface side of the tray 2 through the mesh region 213. Thus, the cleaning effect can be further improved. Further, since the area of the measuring section 22 is 50% or less of the area of the tray main body 21 and the area of the mesh area 213 can be increased, the vibration can be more easily transmitted to the denture 500 on the tray 2. be able to. As a result, the cleaning effect can be enhanced.
