Description

  The present invention relates to an apparatus for ultrasonic cleaning of fresh foods such as vegetables, fruits and shellfish.

  Ultrasonic cleaning apparatuses have been widely used for cleaning precision mechanical parts and glasses for a long time, but recently they are also used for cleaning fresh foods such as vegetables and fruits. A typical example is a rectangular cleaning tank equipped with a cleaning rod in a removable manner. In order to spread the cleaning effect throughout the cleaning tank, many ultrasonic vibrators are installed in the cleaning tank. It is attached to the bottom outer surface (for example, Patent Document 1). Such an ultrasonic cleaning apparatus is excellent in cleaning effect, but requires a large number of ultrasonic vibrators, so that the configuration is complicated and the price is expensive.

  Accordingly, an object of the present invention is to provide an apparatus capable of effectively ultrasonically cleaning an object to be cleaned such as fresh food with a small number of ultrasonic transducers.

The apparatus of the present invention made in view of the above points is an apparatus for ultrasonically cleaning an object to be cleaned as set forth in claim 1, wherein at least one ultrasonic transducer is attached to the outer surface of the bottom. A wash basin of a size that supports the bottom edge on the inclined inner surface at the height of the inverted frustoconical shape of the washing tank is detachably provided inside the washing tank whose upper part is a vertical cylinder and whose lower part is an inverted frustoconical shape. In addition, a ring-shaped pipe provided with discharge holes for discharging the cleaning water supplied into the cleaning tank radially at the height position of the inverted truncated cone shape inside the cleaning tank is arranged coaxially with the cleaning tank. The state in which the cleaning object contained in the cleaning tub is immersed in the cleaning water filled in the cleaning tank by supplying the cleaning water radially into the cleaning tank from the discharge holes provided in the ring-shaped pipe It is characterized by being subjected to ultrasonic cleaning .
Also, the apparatus according to claim 2, wherein, in the apparatus of claim 1, is entirely in the arrangement the filter medium is above the opening of the cleaning tank becomes, the washing water is supplied exceeding the capacity into the cleaning tank Thus, the overflowing wash water is filtered by the filter medium and then discharged to the outside of the wash tank.

  In the ultrasonic cleaning apparatus of the present invention, the lower part of the cleaning tank has an inverted truncated cone shape, and the cleaning tub is supported by the inclined inner surface at the height of the inverted truncated cone shape of the cleaning tank inside the cleaning tank. Therefore, even if the number of ultrasonic vibrators attached to the outer surface of the bottom of the cleaning tank is small, ultrasonic vibrations can be effectively transmitted to the object to be cleaned such as fresh food stored in the cleaning tub for cleaning. .

It is a front view which shows typically the internal structure of an example of the ultrasonic cleaning apparatus of this invention. FIG.

  Hereinafter, although the ultrasonic cleaning apparatus of the present invention will be described with reference to the drawings, the ultrasonic cleaning apparatus of the present invention is not construed as being limited to the following description.

  FIG. 1 is a front view schematically showing an internal structure of an example of the ultrasonic cleaning apparatus of the present invention, and FIG. 2 is a plan view thereof. The ultrasonic cleaning apparatus 1 has a cleaning tank 3 having an upper opening inside a cylindrical housing 2. The upper part of the cleaning tank 3 has a vertical cylindrical shape and the lower part has an inverted frustoconical shape, and one ultrasonic transducer 4 is attached to the center of the outer surface of the bottom part. The cleaning tank 3 is detachably equipped with a cleaning bowl 5 having a size in which the bottom edge is supported by the inclined inner surface of the inverted frustoconical height (not shown in FIG. 2). ). The lower part of the cleaning tank 3 has an inverted frustoconical shape, and the bottom edge of the cleaning bowl 5 is supported by the inclined inner surface at the height of the inverted frustoconical shape of the cleaning tank 3. Even if the number of the ultrasonic transducers is one, the ultrasonic vibration can be effectively transmitted to the object to be cleaned contained in the cleaning basket 5 for cleaning. Further, in the cleaning tank 3, the cleaning water supplied into the cleaning tank is radially provided at a height position lower than the height position at which the cleaning bowl 5 at the height position of the inverted frustoconical shape is supported. A ring-shaped pipe 6 provided with a large number of discharge holes for discharging is arranged coaxially with the cleaning tank 3. For ultrasonic cleaning of the object to be cleaned, the cleaning water supply valve 7 is opened and the cleaning water supplied from the ring-shaped pipe 6 is filled in the cleaning tank 3, and the object to be cleaned contained in the cleaning tub 5 is immersed in the cleaning water. In this state, the ultrasonic transducer 4 is driven by control means (not shown). When additional cleaning water is supplied from the ring-shaped pipe 6 into the cleaning tank during or after the cleaning operation, the dirty cleaning water generated by the cleaning operation moves upward from below the cleaning tank 3. When the cleaning water exceeding the capacity is supplied into the cleaning tank, the dirty cleaning water overflows and is discharged outside the cleaning tank 3. In this ultrasonic cleaning apparatus 1, the filter medium 8 is disposed on the entire surface of the opening above the cleaning tank 3 so as to be accommodated in, for example, a cloth bag and seal the opening (in FIG. 2, the filter medium 8 is not shown). When the dirty cleaning water overflows, the dirty components contained in the dirty cleaning water are filtered by the filter medium 8 and then discharged through the drain pipe 9 attached to the outside of the housing 2. The cleaning water in the cleaning tank can be discharged from the bottom of the cleaning tank 3 by opening the cleaning water discharge valve 10.

  In the ultrasonic cleaning apparatus 1 described above, the number of ultrasonic vibrators attached to the outer surface of the bottom of the cleaning tank 3 is one, but the number of ultrasonic vibrators attached to the outer surface of the bottom of the cleaning tank 3 is two. It may be the above. In the ultrasonic cleaning apparatus 1 described above, the handle 11 is attached to the top of the housing 2 and the caster 12 is attached to the bottom. However, the handle and caster may or may not be provided. Further, the ultrasonic cleaning apparatus 1 may have a lid that covers the upper surface of the housing 2.

  In the ultrasonic cleaning apparatus 1 described above, the filter medium 8 may be, for example, zeolite or the like, but the type of the filter medium 8 can be appropriately selected according to the dirt component contained in the dirty washing water. When the object to be cleaned is fresh food, chemicals or radioactive substances adhering to the food will be included in the cleaning water as a dirty component by ultrasonic cleaning. Is filtered by the filter medium 8 and then discharged to the outside of the washing tank 3 to prevent environmental pollution.

  The ultrasonic cleaning device 1 is suitable for cleaning fresh food such as vegetables, fruits and shellfish, but the object to be cleaned is not limited to fresh food. There may be. When the object to be cleaned is fresh food, it is desirable that the cleaning water to be used is pure water. However, the cleaning water to be used can be appropriately selected according to the type of the cleaning object.

  INDUSTRIAL APPLICABILITY The present invention has industrial applicability in that it can provide a cleaning apparatus that can effectively ultrasonically clean an object to be cleaned such as fresh food with a small number of ultrasonic vibrators.
