Description

本発明は、食器等の洗浄物を洗浄する洗浄機に関するものである。   The present invention relates to a washing machine for washing washed items such as tableware.

この種の洗浄機の一例として、内部に食器等の洗浄物を収容する角型のラックと、当該ラックの上下に回転可能に設けられるとともに、洗浄物に対して上方及び下方からすすぎ湯を噴射するシャワーアームとを備えた食器洗浄機が知られている。このような食器洗浄機は、シャワーアームを回転させながら、シャワーアームの噴射孔から洗浄物に向かって上方及び下方からすすぎ湯を噴射することにより洗浄後の洗浄物に付着した洗浄液を洗い流す。このような食器洗浄機については、例えば以下の公知文献に詳細が開示されている。
特開2003−204914号公報
As an example of this type of washer, a rectangular rack that contains a washing item such as tableware and the like, and a rotating rack that is rotatably provided above and below the rack, and rinsing hot water is sprayed from above and below the washing item. A dishwasher with a shower arm is known. Such a dishwasher flushes the cleaning liquid adhering to the washed product by spraying rinsing water from above and below from the spray hole of the shower arm toward the washed product while rotating the shower arm. About such a dishwasher, the detail is disclosed by the following well-known literature, for example.
JP 2003-204914 A

ところで、上記のような構成の洗浄機では、角型のラック(角型ラック)に収納された洗浄物を全体として均一にすすぎするために、図7に示すようにシャワーアームは角型ラックの中心を回転中心としラックに外接する円領域(外接円領域G)にすすぎ湯を噴射する。しかしながら、このような外接円領域Gにすすぎ湯を噴射すると、洗浄物が存在しない領域にもすすぎ湯を噴射することになるので、遊水部分Eが4箇所に発生してすすぎ湯の無駄が生じるという問題点がある。   By the way, in the washing machine having the above-described configuration, the shower arm is a square rack as shown in FIG. 7 in order to rinse the washing object stored in the square rack (square rack) uniformly. Rinsing water is sprayed onto a circular area (circumscribed circle area G) circumscribing the rack with the center as the center of rotation. However, when rinsing water is sprayed to such circumscribed circle region G, rinsing water is also sprayed to the region where the cleaning object does not exist. There is a problem.

本発明は、このような問題点に鑑みてなされたものであって、角型ラックの内側に効率良くすすぎ湯を噴射することによってすすぎ湯の節水を行うことを目的とするものである。   This invention is made | formed in view of such a problem, Comprising: It aims at saving water of a rinse water by injecting a rinse water efficiently inside a square rack.

上記のような課題を解決するために、本発明では、洗浄物を収容した角型ラックの中心を回転中心として回転しつつ前記角型ラックに向けてすすぎ湯を噴射するすすぎ手段を有する洗浄機であって、前記すすぎ手段は、前記角型ラックの中心に設けられると共にすすぎ湯の供給流路を有する支持軸と、該支持軸に軸受を介して回転自在に支持された管状部材であり、前記供給流路を介して内部に供給されたすすぎ湯を周面の噴射ノズルから前記角型ラックに向けて噴射する第1シャワーアームと、該第1シャワーアーム内に挿入され前記軸受を介して前記支持軸に支持された管状部材であり、前記供給流路を介して内部に供給されたすすぎ湯を前記第1シャワーアームから突出した先端の噴射ノズルから角型ラックに向けて噴射する第2シャワーアームと、前記支持軸と前記軸受との間に設けられ、前記供給流路と前記第1シャワーアームとを連続的に連通させる一方、回転によって第2シャワーアームが角型ラックの四隅に位置したときにのみ前記供給流路と前記第2シャワーアームとを間欠的に連通させるバルブとを備え、回転しつつ第1シャワーアームで角型ラックの内接円領域にすすぎ湯を噴射し、かつ、第2シャワーアームで角型ラックの角領域にすすぎ湯を噴射する、という解決手段を採用している。   In order to solve the above-described problems, in the present invention, a washing machine having a rinsing unit that injects rinsing water toward the square rack while rotating around the center of the square rack containing a washing object. The rinsing means is a support shaft provided at the center of the square rack and having a rinsing water supply flow path, and a tubular member rotatably supported by the support shaft via a bearing, A first shower arm for injecting rinsing hot water supplied through the supply flow channel from an injection nozzle on a peripheral surface toward the square rack; and a first shower arm inserted into the first shower arm through the bearing. A tubular member supported by the support shaft, and a second member that injects the rinsing hot water supplied through the supply flow channel toward the square rack from the injection nozzle at the tip protruding from the first shower arm. Sha -Provided between the arm, the support shaft and the bearing, and continuously communicating the supply flow path and the first shower arm, while the second shower arm was positioned at the four corners of the square rack by rotation. A valve that intermittently communicates the supply flow path and the second shower arm only when spraying rinsing water to the inscribed circle region of the square rack with the first shower arm while rotating, and A solution is adopted in which rinsing water is sprayed onto the corner area of the square rack with the second shower arm.

このような本発明によれば、第1シャワーアームと第2シャワーアームとのうち、外側に位置する第1シャワーアームによって角型ラックの内接円領域にすすぎ湯が噴射される一方、この第1シャワーアームの内側に位置する第2シャワーアームによって角型ラックの角領域にすすぎ湯が噴射される。したがって、従来のように遊水部分が生じないので、すすぎ湯を節水することができる。   According to the present invention, the rinsing hot water is sprayed to the inscribed circle region of the square rack by the first shower arm located on the outer side of the first shower arm and the second shower arm. Rinsing water is sprayed to the corner area of the square rack by the second shower arm located inside the one shower arm. Therefore, there is no reclaimed water portion as in the prior art, so that rinse water can be saved.
