Description

  The present invention relates to an automatic rice washing apparatus.

  Conventionally, in commercial kitchens of general hotels, restaurants, sushi restaurants, etc., automatic rice washing equipment for business use has been used to wash a large amount of rice efficiently with stable quality without manpower. .

  This automatic rice washing apparatus is a sewage that stirs the polished rice and washing water introduced into the rice washing container, and the sewage discharged from the washing sewage discharge port provided at one end of the rice washing container. It is configured to wash the polished rice by repeating the discharge process. The cleaning sewage discharge port is connected to a drainage groove through a distribution pipe, and the cleaning sewage discharged from the cleaning sewage discharge port flows directly into the drainage groove.

And after repeating this agitation process and sewage discharge process sufficiently, the rice cooking water required for polished rice and rice cooking is simultaneously discharged from the rice washing outlet provided at the lower part of the rice washing container, and these are discharged below the rice washing outlet. In the receiving container (for example, an inner pot or a bucket) placed in the box, the washing process is completed. Patent Document 1 discloses an automatic rice washing apparatus provided with a receiving container setting plate for setting the receiving container below the rice washing outlet, and the receiving container setting plate is matched to the size of the receiving container. Those that can be installed in appropriate locations are known.

  On the other hand, in recent years, in order to increase the customer accommodation rate and increase profits, the kitchen space has been reduced. Therefore, there is only a space in the kitchen where only a minimum amount of equipment can be arranged, and it is becoming difficult to secure a space for arranging the automatic rice washing apparatus.

  Therefore, in order to effectively use the small space of the kitchen, it is desirable to arrange the automatic rice washing device above the sink. In such an automatic rice washing device arrangement, dishes and pans can be washed inside the sink, and a receiving container is placed on the bottom surface of the sink instead of the receiving container placing plate as described in Patent Document 1. Since it can be placed, it is very effective for the food and beverage industry where the kitchen space is becoming smaller. Furthermore, by arranging the automatic rice washing device above the sink, it becomes possible to flow the washing waste water discharged from the washing waste water discharge port to the sink during the waste water discharge treatment. By doing so, for the automatic rice washing device It is not necessary to prepare a separate drainage channel, and it is possible to prevent the entry of odors, rats, insects, etc. from the drainage channel.

  However, as described above, when the automatic rice washing apparatus is disposed above the sink, the following problems occur. In other words, before the milled rice and rice cooking water are discharged from the washing rice discharge port, the sink is filled with the cleaning sewage discharged from the cleaning sewage discharge port if the receiving container is prepared in advance on the bottom of the sink. As a result, a phenomenon that the receiving container floats from the bottom surface of the sink occurred.

  Thus, when the receiving container floats from the bottom surface of the sink, the placement position of the receiving container is shifted from the initial position, and the polished rice and rice cooking water discharged from the rice washing outlet cannot be reliably stored. It will be. Therefore, the worker must place the receiving container after confirming that the sewage draining process is finished and the cleaning sewage is no longer in the sink, which makes the washing process complicated and reduces the work efficiency. Caused.

  Then, this invention is made | formed in view of the said subject, Comprising: It aims at provision of the automatic rice-washing apparatus which can perform a rice-washing operation | work rapidly, while accommodating the discharged | emitted rice reliably.

  In order to solve the above problems, an automatic rice washing apparatus of the present invention comprises a rice washing container for containing rice and water, a stirring member for stirring rice and water contained in the rice washing container, and a rice stirred by the stirring member. In an automatic rice washing apparatus comprising a rice washing section having a rice washing outlet for discharging water, and a laying table for laying a receiving container for storing rice discharged from the rice rinsing discharge port, A receiving position where the receiving port of the receiving container is below the rice washing outlet, and is located above the bottom surface of the sink located below the rice washing portion with a space therebetween; and a retreating position that opens above the sink. It is characterized by being provided so as to be movable.

  Since the present invention includes a setting table for setting the receiving container above the sink, by placing the receiving container on the setting table, the receiving container can be moved from the initial position even if cleaning sewage flows into the sink. It will not shift. Therefore, even if the worker has placed the receiving container in advance, the rice discharged by the placed receiving container can be reliably stored, so that the working efficiency can be improved. Further, since the table can be retracted and the upper part of the sink can be opened, the sink can be used for cleaning dishes and the like, which can contribute to the improvement of work efficiency in the kitchen.
