Description

本発明は、洗浄ノズルより食器類に向けて洗浄水を噴射して食器類を洗浄する卓上型の食器洗い機に関するものである。   The present invention relates to a table-type dishwasher for cleaning dishes by spraying washing water from a washing nozzle toward the dishes.

従来、この種の食器洗い機は、図3から図6に示すように構成されていた。以下、その構成について説明する。図3から図6に示すように、食器洗い機1は、内部に洗浄槽2が設けられており、この洗浄槽2の底部に排水口3が設けられ、この排水口3の側部に連通したポンプ室にモータ4によって駆動される洗浄ポンプ5が配設され、洗浄ポンプ5により洗浄水を洗浄槽2の内部に循環させるように構成されている。   Conventionally, this type of dishwasher has been configured as shown in FIGS. Hereinafter, the configuration will be described. As shown in FIGS. 3 to 6, the dishwasher 1 is provided with a washing tub 2 inside, a drainage port 3 is provided at the bottom of the washing tub 2, and communicates with the side of the drainage port 3. A cleaning pump 5 driven by a motor 4 is disposed in the pump chamber, and the cleaning pump 5 is configured to circulate cleaning water inside the cleaning tank 2.

この循環は、洗浄水が排水口3から洗浄ポンプ5に吸い込まれ、洗浄ポンプ5より洗浄槽2の内底部に配設された洗浄ノズル6に供給され、この洗浄ノズル6から食器類7に向けて噴射され、食器類7を洗浄した後、再び排水口3に戻るという経路で行われる。   In this circulation, the washing water is sucked into the washing pump 5 from the drain port 3 and is supplied from the washing pump 5 to the washing nozzle 6 disposed in the inner bottom portion of the washing tank 2, from the washing nozzle 6 toward the dishes 7. After the tableware 7 is washed, the process returns to the drain port 3 again.

洗浄ノズル6と洗浄槽2の底部との間には、洗浄水加熱用のヒータ8が配設されている。また、洗浄ノズル6の上方には、食器類7を整然と配置することで食器類7に対して洗浄水を効果的に噴射し、食器類7の洗浄を効率的に行えるように構成した食器かご9が設置されている。   A cleaning water heater 8 is disposed between the cleaning nozzle 6 and the bottom of the cleaning tank 2. In addition, the tableware basket is configured so that the tableware 7 is arranged in an orderly manner above the cleaning nozzle 6 so that cleaning water can be effectively sprayed onto the tableware 7 and the tableware 7 can be cleaned efficiently. 9 is installed.

また、洗浄槽2は前方に開口しており、その前面部には、前方に開閉自在な蓋10が取り付けられている。排水ポンプ11は、排水口3から洗浄水を吸い込み、排水ホース12を通して洗浄水を機外に排出するように構成されている。   Moreover, the washing tank 2 is opened forward, and a lid 10 that can be opened and closed forward is attached to the front surface thereof. The drain pump 11 is configured to suck the cleaning water from the drain port 3 and discharge the cleaning water to the outside through the drain hose 12.

洗浄槽2内に溜められる洗浄水は給水ホース13から供給される。洗浄槽2に連通した水位検知手段14により所定水位まで洗浄水が供給されたことを検知すると、制御手段15は給水弁16を閉じて洗浄水供給を停止する。   The cleaning water stored in the cleaning tank 2 is supplied from the water supply hose 13. When the water level detection means 14 communicating with the cleaning tank 2 detects that the cleaning water has been supplied to a predetermined water level, the control means 15 closes the water supply valve 16 and stops the supply of the cleaning water.

従来の卓上型の食器洗い機において、水位検知手段14は食器洗い機1本体右奥に設置されている。これは回転する洗浄ノズル6の回転軌跡を避けるためであり、かつ、食器洗い機1本体背面中央付近は、排水ホース12及び給水ホース13の接続部が設置されているためである(例えば、特許文献1参照)。
特開2003−47585号公報
In a conventional tabletop dishwasher, the water level detection means 14 is installed in the right rear of the dishwasher 1 main body. This is for avoiding the rotation trajectory of the rotating washing nozzle 6 and for connecting the drainage hose 12 and the water supply hose 13 near the center of the back of the dishwasher 1 main body (for example, Patent Document 1). 1).
JP 2003-47585 A

上記のような構成の従来の食器洗い機では、本体に対して水位検知手段が洗浄槽下方の端部に設けられていたため、本体が傾斜して設置された場合、端部に設けられた水位検知手段近傍の増減差が大きい。例えば、本体が水位検知手段が水平に置かれたときに比べ水位を高く検知してしまうように、傾斜して設置された場合、所定の水位に達していないにも関わらず給水が終了してしまうので、洗浄用ポンプが空気を吸い込む現象が生じることにより洗浄性能が不安定になる場合があった。また、逆に、水位検知手段が検知する水位が低くなるように、本体が傾斜して設置された場合、所定量より多くの水が給水されてしまい、余分な水を使ってしまっていた。   In the conventional dishwasher configured as described above, since the water level detection means is provided at the end below the washing tank with respect to the main body, when the main body is installed at an inclination, the water level detection provided at the end is detected. The increase / decrease difference near the means is large. For example, when the main body is installed at an angle so that the water level is detected higher than when the water level detecting means is placed horizontally, the water supply is terminated even though the predetermined water level has not been reached. Therefore, the cleaning performance may become unstable due to the phenomenon that the cleaning pump sucks air. On the other hand, when the main body is installed at an inclination so that the water level detected by the water level detecting means is lowered, more water is supplied than a predetermined amount, and excess water is used.

よって、洗浄性能を安定させるために、本体が傾斜して設置された場合にも、所定量の洗浄水量を過不足なく本体内に給水する必要があるという課題があった。   Therefore, in order to stabilize the cleaning performance, there is a problem that even when the main body is installed at an inclination, it is necessary to supply a predetermined amount of cleaning water into the main body without excess or deficiency.

本発明は、上述の課題を解決するため、簡単な構成にて、本体を傾斜させて設置したときの検知水位の変動を少なく抑え、洗浄性能を安定させるための洗浄水量を必要最低限にした食器洗い機を提供することを目的としている。   In order to solve the above-mentioned problems, the present invention minimizes the amount of washing water for stabilizing the washing performance by suppressing the fluctuation of the detection water level when the main body is inclined and installed with a simple configuration. It aims to provide a dishwasher.

本発明の食器洗い機は、食器を収容する洗浄槽と、前記洗浄槽内の底部に溜められる洗浄水の水位を検知する水位検知手段と、洗浄水を食器類に噴射する洗浄ノズルとを備え、前記水位検知手段を、前記洗浄槽の下方で略左右中央に配した食器洗い機である。   The dishwasher of the present invention comprises a washing tank for storing tableware, water level detecting means for detecting the level of washing water stored at the bottom of the washing tank, and a washing nozzle for injecting washing water into the dishes, It is a dishwasher in which the water level detection means is arranged at the center of the left and right sides below the washing tank.

この構成によると、食器洗い機をキッチンのカウンタートップ等の上に設置した際に左右段差があった場合においても、水位検知手段が検知した水位によって決まる洗浄水供給量が比較的安定するため、比較的少ない洗浄水量にて洗浄用ポンプが空気を吸い込むことなく洗浄運転でき、安定した洗浄性能を確保できる。   According to this configuration, even when there is a step difference when installing the dishwasher on the kitchen countertop, etc., the wash water supply determined by the water level detected by the water level detection means is relatively stable. The washing pump can perform washing operation without sucking air with a small amount of washing water, ensuring stable washing performance.

本発明の食器洗い機によると、卓上型の食器洗い機をキッチンのカウンタートップ等の上に設置した際に左右段差があった場合においても、水位検知手段が検知した水位によって決まる洗浄水供給量が比較的安定するため、洗浄用ポンプが空気を吸い込むことなく洗浄運転でき、より少ない洗浄水量にて安定した洗浄性能を確保できる。   According to the dishwasher of the present invention, even when there is a step difference when a desktop dishwasher is installed on a kitchen countertop or the like, the supply amount of washing water determined by the water level detected by the water level detection means is compared. Therefore, the cleaning pump can perform a cleaning operation without sucking air, and a stable cleaning performance can be secured with a smaller amount of cleaning water.

第1の発明は、食器を収容する洗浄槽と、前記洗浄槽内の底部に溜められる洗浄水の水位を検知する水位検知手段と、洗浄水を食器類に噴射する洗浄ノズルとを備え、前記水位検知手段を、前記洗浄槽の下方で略左右中央に配した食器洗い機としたもので、卓上型の食器洗い機をキッチンのカウンタートップ等の上に設置した際に左右段差があった場合においても、水位検知手段が検知した水位によって決まる洗浄水供給量が比較的安定するため、比較的少ない洗浄水量にて洗浄用ポンプが空気を吸い込むことなく洗浄運転でき、安定した洗浄性能を確保できる。   1st invention is equipped with the washing tank which stores tableware, the water level detection means which detects the water level of the washing water stored on the bottom in the washing tank, and the washing nozzle which injects washing water into the tableware, The water level detection means is a dishwasher arranged in the center of the left and right sides below the washing tank. Even when there is a step difference when a desktop dishwasher is installed on a kitchen countertop, etc. Since the cleaning water supply amount determined by the water level detected by the water level detection means is relatively stable, the cleaning pump can perform a cleaning operation without sucking air with a relatively small amount of cleaning water, and stable cleaning performance can be ensured.

第2の発明は、上記第1の発明において、水位検知手段を、洗浄槽の下方で略前後中央に配した食器洗い機としたもので、卓上型の食器洗い機をキッチンのカウンタートップ等の上に設置した際に前後の段差があった場合においても、比較的少ない洗浄水量にて洗浄用ポンプが空気を吸い込むことなく洗浄運転でき、安定した洗浄性能を確保できる。   The second invention is the above-mentioned first invention, wherein the water level detecting means is a dishwasher arranged substantially in the front and rear in the lower part of the washing tank, and the desktop dishwasher is placed on the countertop of the kitchen or the like. Even when there are steps before and after installation, the cleaning pump can perform a cleaning operation without sucking air with a relatively small amount of cleaning water, and stable cleaning performance can be secured.

以下、本発明の食器洗い機の一実施の形態について、図面を参照して説明する。なお、従来例の食器洗い機と同じ構成要素は同一符号を付して説明を省略する。また、本発明は本実施の形態に限定されるものではない。   Hereinafter, an embodiment of a dishwasher according to the present invention will be described with reference to the drawings. In addition, the same component as the dishwasher of a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description. The present invention is not limited to the present embodiment.

(実施の形態1)
図1は本発明の実施の形態1における食器洗い機の側断面図、図2は同食器洗い機の平面断面図である。本実施の形態の食器洗い機17は、図1および図2に示すように、洗浄槽2内に食器かご9を設けており、この食器かご9に収容した食器類7を洗浄するために、複数の回転洗浄ノズル18を設けて洗浄液を食器類7に噴射するものである。洗浄槽2内の底部に溜められる洗浄水の水位を検知する水位検知手段19は洗浄槽2の底面の外側で左右および前後の略中央に配置している。
(Embodiment 1)
FIG. 1 is a side sectional view of the dishwasher according to Embodiment 1 of the present invention, and FIG. 2 is a plan sectional view of the dishwasher. As shown in FIGS. 1 and 2, the dishwasher 17 according to the present embodiment has a table basket 9 in the washing tub 2, and a plurality of dishes 7 are washed in order to clean the tableware 7 accommodated in the table basket 9. The rotary cleaning nozzle 18 is provided to spray the cleaning liquid onto the dishes 7. The water level detection means 19 for detecting the level of the cleaning water stored in the bottom of the cleaning tank 2 is arranged at the center of the left and right and front and rear outside the bottom surface of the cleaning tank 2.

水位検知手段19を洗浄槽2の左右および前後の略中央に配置するために、本実施の形態の食器洗い機17は、洗浄ノズル18を従来よりも薄型とするとともに、軸部のがたつきを回転に必要な最小限としている。また水位検知手段19を低背型としている。水位検
知手段19を水圧による水位検知方式としても低背とすることができる。洗浄ノズル18から食器類7に向かって噴出する洗浄水の勢い、流量を必要最低限になるよう最適設定することで、洗浄槽2に溜めることが必要な洗浄水量をより少なくすることにより、水位検知手段19の設置高さをより低くすることも有効である。
In order to dispose the water level detecting means 19 at the left and right and the front and rear of the washing tank 2, the dishwasher 17 of the present embodiment has a washing nozzle 18 that is thinner than the conventional one and has a shaki shaft. The minimum required for rotation. The water level detection means 19 is a low profile type. The water level detection means 19 can also be made low-profile as a water level detection method using water pressure. By optimally setting the momentum and flow rate of the washing water ejected from the washing nozzle 18 toward the tableware 7 to the minimum necessary, the amount of washing water that needs to be stored in the washing tank 2 is reduced, thereby reducing the water level. It is also effective to lower the installation height of the detection means 19.

以上のように構成した食器洗い機によれば、水位検知手段19を洗浄槽2の左右および前後の略中央に配置しているため、本実施の形態の食器洗い機17をキッチンのカウンタートップ上に設置した際に左右あるいは前後の段差があった場合においても、水位検知手段が検知した水位によって決まる洗浄水供給量が比較的安定するため、余分な洗浄水を必要とすることなくして洗浄用ポンプが空気を吸い込むことのない洗浄運転ができ、安定した洗浄性能を確保した食器洗い機とすることができる。   According to the dishwasher configured as described above, since the water level detection means 19 is arranged at the center of the left and right and front and rear of the washing tub 2, the dishwasher 17 of the present embodiment is installed on the counter top of the kitchen. Even when there is a step difference between left and right or front and rear, the cleaning water supply amount determined by the water level detected by the water level detection means is relatively stable, so that the cleaning pump can be operated without requiring extra cleaning water. The dishwasher can perform a washing operation without sucking air and secure stable washing performance.

また、水位検知手段19を、洗浄槽2の下方で略前後中央に配したので、卓上型の食器洗い機をキッチンのカウンタートップ等の上に設置した際に前後の段差があった場合においても、水位検知手段19が精度良く水位の検知を行うので、比較的少ない洗浄水量にて洗浄用ポンプが空気を吸い込むことなく洗浄運転でき、安定した洗浄性能を確保できる。   In addition, since the water level detection means 19 is arranged substantially in the front-rear center below the washing tank 2, even when there is a front-rear step when a desktop dishwasher is installed on a kitchen countertop or the like, Since the water level detection means 19 detects the water level with high accuracy, the cleaning pump can perform a cleaning operation without sucking air with a relatively small amount of cleaning water, and stable cleaning performance can be ensured.

本発明の食器洗い機は、洗浄槽内の底部に溜められる洗浄水の水位を検知する水位検知手段を、洗浄槽の下方で略左右中央に配した卓上型の食器洗い機としたことで、卓上型の食器洗い機をキッチンのカウンタートップ上に設置した際に左右段差があった場合においても、水位検知手段が検知した水位によって決まる洗浄水供給量が比較的安定するため、余分な洗浄水を必要とすることなく洗浄用ポンプが空気を吸い込むことなく洗浄運転でき、安定した洗浄性能を確保した食器洗い機とすることができるので、キッチンのカウンタートップ等の上に設置して使用する卓上型の食器洗い機等として有用である。   The dishwasher of the present invention is a tabletop dishwasher in which the water level detection means for detecting the level of the washing water stored at the bottom of the washing tank is a tabletop dishwasher arranged substantially in the left and right center below the washing tank. Even when there is a difference in level when the dishwasher is installed on the kitchen countertop, the amount of washing water determined by the water level detected by the water level detection means is relatively stable. Because the washing pump can be operated without inhaling air and it can be a dishwasher that ensures stable washing performance, it is a desktop dishwasher that is installed on the kitchen countertop etc. Useful as such.
