Description

本発明は、食器等の被洗浄物に洗浄水を噴射して洗浄する食器洗い機に関するものである。   The present invention relates to a dishwasher for cleaning by spraying cleaning water onto an object to be cleaned such as tableware.

従来の一般的な食器洗い機は、図4に示すように構成されていた(例えば、特許文献1参照)。以下、その構成について説明する。   A conventional general dishwasher is configured as shown in FIG. 4 (see, for example, Patent Document 1). Hereinafter, the configuration will be described.

図4に示すように、食器洗い機本体1は、内部に洗浄槽2を設けており、洗浄槽2の上方は開放されており、洗浄槽2を引き出した時に、上方からの食器などの被洗浄物10の出し入れが可能となっている。また、洗浄槽2内へは給水弁3により水または湯が供給されるようになっている。   As shown in FIG. 4, the dishwasher main body 1 is provided with a washing tub 2 inside, the upper portion of the washing tub 2 is open, and when the washing tub 2 is pulled out, the dishes to be washed from above are washed. The object 10 can be taken in and out. Further, water or hot water is supplied into the cleaning tank 2 by a water supply valve 3.

ここで、その洗浄水の供給は、水位センサ(図示せず)を利用して適切な水位に設定し、給水弁3からの給水を自動的に止める。洗浄槽2の底部には排水孔4を設け、この排水孔4に連通し、モータ(図示せず)によって駆動される洗浄ポンプ5を取り付け、この洗浄ポンプ5により洗浄水を洗浄槽2の内部に循環するよう構成している。また、排水孔4には、洗浄やすすぎ時に被洗浄物10から落ちた残滓を捕集する残滓フィルタ6を具備している。また、洗浄槽2の近傍には、洗浄槽2へ風を送るための送風手段となる乾燥ファン7を設けている。洗浄槽2の前面には、洗浄槽2からの空気を排出する排気口8を設けている。   Here, the supply of the washing water is set to an appropriate water level using a water level sensor (not shown), and water supply from the water supply valve 3 is automatically stopped. A drain hole 4 is provided at the bottom of the cleaning tank 2, and a cleaning pump 5 that is connected to the drain hole 4 and is driven by a motor (not shown) is attached. The cleaning pump 5 supplies cleaning water to the inside of the cleaning tank 2. It is configured to circulate. Further, the drain hole 4 is provided with a residue filter 6 that collects residues that have fallen from the object to be cleaned 10 when it is easily washed. Further, in the vicinity of the cleaning tank 2, a drying fan 7 serving as a blowing unit for sending air to the cleaning tank 2 is provided. An exhaust port 8 for discharging air from the cleaning tank 2 is provided on the front surface of the cleaning tank 2.

上記構成における従来の食器洗い機の動作を説明する。   The operation of the conventional dishwasher with the above configuration will be described.

洗浄槽2内に供給された洗浄水は、残滓フィルタ6を通過して洗浄ポンプ5に吸い込まれ、洗浄ポンプ5より洗浄槽2の内底部に設けた洗浄ノズル9に供給される。洗浄ノズル9から噴射された洗浄水は、食器かご12に収納された被洗浄物10を洗浄した後、再び排水孔4に戻るという経路で循環する。この際、被洗浄物10から脱落した残滓等は、洗浄水とともに残滓フィルタ6に流入し、この残滓フィルタ6を通過できない大きさの残滓は残滓フィルタ6に捕集される。   The cleaning water supplied into the cleaning tank 2 passes through the residue filter 6, is sucked into the cleaning pump 5, and is supplied from the cleaning pump 5 to the cleaning nozzle 9 provided at the inner bottom portion of the cleaning tank 2. The washing water sprayed from the washing nozzle 9 circulates along a route that returns to the drain hole 4 again after washing the article 10 to be washed contained in the tableware basket 12. At this time, the residue or the like dropped off from the object to be cleaned 10 flows into the residue filter 6 together with the cleaning water, and the residue having a size that cannot pass through the residue filter 6 is collected by the residue filter 6.

また、洗浄ノズル9と洗浄槽2の底部との間には、洗浄水加熱用のヒータ11を装備し、洗浄ノズル9の上方には、被洗浄物10を整然と配置でき、洗浄水を効果的に被洗浄物10に噴射するように構成した食器かご12を設置して効率的に洗浄を行っている。さらに、制御手段13により、給水弁3や洗浄ポンプ5等の電装部品を駆動、制御している。   In addition, a heater 11 for heating the cleaning water is provided between the cleaning nozzle 9 and the bottom of the cleaning tank 2, and the object to be cleaned 10 can be arranged in an orderly manner above the cleaning nozzle 9, so that the cleaning water can be effectively used. The tableware basket 12 configured to be sprayed on the object to be cleaned 10 is installed for efficient cleaning. Further, the control means 13 drives and controls electrical components such as the water supply valve 3 and the cleaning pump 5.

また、最終加熱すすぎを高温で行い、洗浄槽2内を高温に保つことにより、被洗浄物10に熱をもたせ、乾燥し易くする。さらに、洗浄槽2内に乾燥ファン7によって供給された風は、ヒータ11により暖められ、洗浄槽2内に配置された被洗浄物10に残った水滴を蒸発させる。水分を含んだ温風は、洗浄槽2内を充満しながら、洗浄槽2に設けた排気口8より排出される。乾燥行程初期は高温の蒸気が大量に発生し、時間経過とともに徐々に蒸気が減少し、より乾燥した排気が排出されていく。

Further, the final heating rinse is performed at a high temperature, and the cleaning tank 2 is kept at a high temperature, so that the object to be cleaned 10 is heated and easily dried. Further, the wind supplied by the drying fan 7 into the cleaning tank 2 is warmed by the heater 11 to evaporate water droplets remaining on the object 10 to be cleaned disposed in the cleaning tank 2. The warm air containing moisture is discharged from the exhaust port 8 provided in the cleaning tank 2 while filling the cleaning tank 2. In the initial stage of the drying process, a large amount of high-temperature steam is generated, and the steam gradually decreases with the passage of time, and the dried exhaust gas is discharged.
JP 2001-61754 A

しかしながら、このような従来の食器洗い機の構成では、乾燥行程の初期に、高温になった排気蒸気が排気口8より勢いよく排出されるために、食器洗い機が設置された台所内が高温多湿になり、特に夏場は不快を感じたり、発生した蒸気がキッチンの天板などに直接吹きかかることにより結露が発生し、例えば天板まわりの木材などは高温多湿な環境にさらされ、結露水などにより腐って朽ちたり、金属部分については蒸気にさらされることで錆びやすくなるという種々の課題があった。   However, in such a conventional dishwasher configuration, exhaust steam that has reached a high temperature is exhausted from the exhaust port 8 at the beginning of the drying process, so the kitchen in which the dishwasher is installed becomes hot and humid. Especially in the summer, dew is generated by feeling uncomfortable, or the generated steam blows directly on the top plate of the kitchen.For example, the wood around the top plate is exposed to a hot and humid environment, and the condensed water There were various problems such as rot and decay, and metal parts were easily rusted by exposure to steam.

本発明は上記従来の課題を解決するもので、高価な電装部品を使用することなく、乾燥時に外部に排出される蒸気量を調節して、排気による室温の急激な温度上昇を防止し、周辺物および環境への影響が少ない食器洗い機を提供することを目的としている。   The present invention solves the above-mentioned conventional problems, and without using expensive electrical parts, adjusts the amount of steam discharged outside during drying, prevents sudden temperature rise due to exhaust, The object is to provide a dishwasher that has little impact on things and the environment.

前記従来の課題を解決するために、本発明の食器洗い機は、被洗浄物を収納すると共に洗浄する洗浄槽と、前記洗浄槽に風を送る送風手段と、前記洗浄槽内の空気を外部に排気するための複数の送風経路と、開閉動作で前記複数の送風経路を切り替える弁機構とを備え、排気される前記空気の風圧で前記弁機構の開閉を行うようにしたもので、ソレノイドやギヤードモータといった高価な電装部品を用いることなく、簡単に風圧で弁機構を開閉させることができるので、例えば、最終すすぎ行程の終わりから乾燥行程の初期にかけて、送風手段の風圧を低下させて、弁機構を閉じて、大量に発生した蒸気を含む空気を、蒸気の排出を抑制する送風経路側に切り替えるようにすれば、外部への蒸気の排出が抑えられ、蒸気による周辺物への被害を防止したり、台所内が高温多湿になることによる不快感を緩和することができる。   In order to solve the above-described conventional problems, a dishwasher according to the present invention includes a washing tank for storing and washing an object to be washed, a blowing unit for sending air to the washing tank, and air in the washing tank to the outside. A plurality of ventilation paths for exhausting, and a valve mechanism that switches the plurality of ventilation paths by opening and closing operations, and the valve mechanism is opened and closed by the wind pressure of the exhausted air; a solenoid or geared The valve mechanism can be easily opened and closed by wind pressure without using expensive electrical components such as a motor. For example, the valve mechanism is lowered by reducing the wind pressure of the blowing means from the end of the final rinsing process to the beginning of the drying process. By closing the air and switching the air containing a large amount of steam to the air flow path side that suppresses the discharge of steam, the discharge of steam to the outside can be suppressed, and the damage to the surroundings due to the steam Prevention or, in the kitchen can be relaxed discomfort caused by high temperatures and humidity.

本発明の食器洗い機は、安価な構成で、排出される蒸気量を調節することができるので、発生した蒸気がキッチンの天板などに直接吹きかかることにより結露が発生し、例えば天板まわりの木材などは高温多湿な環境にさらされ、結露水などにより腐って朽ちたり、金属部分については蒸気によりさらされ錆びやすくなるという不具合や急激な台所環境の高温多湿化による不快感を未然に防止することができる。   Since the dishwasher of the present invention can adjust the amount of steam discharged with an inexpensive configuration, condensation occurs when the generated steam blows directly on the top plate of the kitchen, for example, around the top plate. Wood and other materials are exposed to high-temperature and high-humidity environments, and they can be prevented from decaying due to condensed water, etc. be able to.

第1の発明は、被洗浄物を収納すると共に洗浄する洗浄槽と、前記洗浄槽に風を送る送風手段と、前記洗浄槽内の空気を外部に排気するための複数の送風経路と、開閉動作で前記複数の送風経路を切り替える弁機構とを備え、排気される前記空気の風圧で前記弁機構の開閉を行うようにしたもので、ソレノイドやギヤードモータといった高価な電装部品を用いることなく、簡単に風圧で弁機構を開閉させることができるので、例えば、最終すすぎ行程の終わりから乾燥行程の初期にかけて、送風手段の風圧を低下させて、弁機構を閉じて、大量に発生した蒸気を含む空気を、蒸気の排出を抑制する送風経路側に切り替えるようにすれば、外部への蒸気の排出が抑えられ、蒸気による周辺物への被害を防止したり、台所内が高温多湿になることによる不快感を緩和することができる。   According to a first aspect of the present invention, there is provided a cleaning tank for storing and cleaning an object to be cleaned, a blowing means for sending air to the cleaning tank, a plurality of blowing paths for exhausting the air in the cleaning tank to the outside, and opening and closing A valve mechanism that switches the plurality of air flow paths in operation, and is configured to open and close the valve mechanism with the wind pressure of the exhausted air, without using expensive electrical components such as a solenoid or a geared motor, Since the valve mechanism can be easily opened and closed by wind pressure, for example, from the end of the final rinsing process to the beginning of the drying process, the wind pressure of the blowing means is lowered, the valve mechanism is closed, and a large amount of generated steam is contained. If the air is switched to the air flow path side that suppresses the discharge of steam, the discharge of steam to the outside can be suppressed, damage to surrounding objects due to the steam can be prevented, and the kitchen can become hot and humid. It is possible to alleviate the discomfort caused.

第2の発明は、特に、第1の発明の食器洗い機において、風圧が低いときに空気が通過する送風経路に除湿機能手段を配したもので、例えば、最終すすぎ行程の終わりから乾燥行程の初期にかけて多量に蒸気が発生する際に、送風手段の風圧を低下させて弁機構を動作させて、除湿機能手段を配した送風経路側に、大量の蒸気を含む空気が流入するように切り替えるようにすれば、外部への蒸気の排出が大幅に抑えられ、台所内が高温多湿になることによる不快感を低減させるだけでなく、発生した蒸気がキッチンの天板などに直接吹きかかることにより結露が発生し、例えば天板まわりの木材などが高温多湿な環境にさらされ、結露水などにより腐って朽ちたり、金属部分については蒸気によりさらされ錆びやすくなるという不具合を未然に防止することができる。   The second invention is the dishwasher according to the first invention, in which the dehumidifying function means is arranged in the air passage through which air passes when the wind pressure is low. For example, from the end of the final rinsing process to the initial stage of the drying process. When a large amount of steam is generated, the valve mechanism is operated by lowering the wind pressure of the blowing means so that air containing a large amount of steam flows into the blowing path side where the dehumidifying function means is arranged. As a result, the discharge of steam to the outside is greatly suppressed, reducing not only the discomfort caused by the hot and humid interior of the kitchen, but also condensation is caused by the generated steam spraying directly on the top plate of the kitchen. For example, the wood around the top plate is exposed to a hot and humid environment, it decays due to condensed water, etc., and the metal part is exposed to steam and becomes prone to rust. It is possible to prevent.

第3の発明は、特に、第2の発明の除湿機能手段として調湿性能樹脂を用いたもので、調湿性能樹脂は通過する空気の湿気を取り除いて乾燥した空気を送り、低温になると水分を放出して復帰することができるため、特別な復帰のための手段を必要とせず、簡単な構成でその能力を維持し、通過する空気の湿気を取り除いて乾燥空気を送ることが可能なため、台所環境が高温多湿になることによる不快感を低減させるだけでなく、発生した蒸気がキッチンの天板などに直接吹きかかることにより結露が発生し、例えば天板まわりの木材などは高温多湿な環境にさらされ、結露水などにより腐って朽ちたり、金属部分については蒸気によりさらされ錆びやすくなるという不具合を未然に防止することができる。   In particular, the third invention uses a humidity control resin as the dehumidifying function means of the second invention. The humidity control resin removes moisture from the passing air and sends dry air. Because it is possible to return by returning the air, it does not require any special means for return, maintains its ability with a simple configuration, and can remove the humidity of the passing air and send dry air In addition to reducing the discomfort caused by the hot and humid kitchen environment, condensation is generated when the generated steam blows directly onto the top of the kitchen.For example, the wood around the top is hot and humid. It is possible to prevent problems such as exposure to the environment, decay and decay due to condensed water, and exposure of metal parts to steam and rusting.

第4の発明は、第1〜3のいずれか一つの発明の食器洗い機において、洗い、すすぎ、乾燥の各行程を制御する制御手段を備え、前記制御手段は、乾燥行程において、初期の段階では風圧が低く、所定時間が経過した後、風圧を高めるように送風手段を制御するもので、乾燥行程の初期に、風圧を低下させて弁機構を動作させて、すすぎ行程で暖められた空気が、高温の蒸気となって排出される排気量を一時的に抑える排気経路側に切り替えるようにし、乾燥工程が所定時間経過して排気温度がある程度低くなってきたら、風圧を高くして弁機構を、空気の排出量を増加させる排気経路側に切り替えることで、外部に排出される蒸気の蒸気量や空気温度を急激に上昇させることなく使用することができ、蒸気による周辺物への被害や台所内が高温多湿になることを防止することができ、かつ、乾燥時間を延ばすことなく、乾燥性能を確保することができる。   According to a fourth invention, in the dishwasher according to any one of the first to third inventions, the dishwasher includes control means for controlling each process of washing, rinsing, and drying, and the control means is an initial stage in the drying process. The air pressure is controlled so that the wind pressure is increased after a predetermined time has passed since the wind pressure is low.At the initial stage of the drying process, the valve pressure is lowered and the valve mechanism is operated, and the air warmed in the rinsing process is Then, switch to the exhaust path side to temporarily suppress the amount of exhaust discharged as high-temperature steam. By switching to the exhaust path side to increase the amount of air discharged, it can be used without suddenly increasing the amount of steam discharged to the outside and the air temperature, causing damage to the surroundings and the kitchen Inside It can be prevented from becoming hot and humid, and without extending the drying time, it is possible to ensure the drying performance.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものでは無い。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

In addition, about the same part as a prior art example, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

本実施の形態における食器洗い機は、図1に示すように、食器洗い機本体1に対して出し入れ自在の洗浄槽2を備え、その洗浄槽2は、被洗浄物10の出し入れを容易にするために従来同様上方に開放している。   As shown in FIG. 1, the dishwasher according to the present embodiment includes a washing tub 2 that can be taken in and out of the dishwasher main body 1, and the washing tub 2 facilitates taking in and out of the object to be cleaned 10. It is open upward as in the past.

図2に示すように、洗浄槽2は、一方の側壁2aの後部かつ上部に設けられ洗浄槽2内部と連通する排出口2bと、前面2cの上部に設けられた排気口15と、側壁2aに設けられ前記排出口2bと排気口15とを連通する送風経路14とを備えており、洗浄槽2内の蒸気が、排出口2b、送風経路14、排気口15を経て外部に排出されるようになっている。   As shown in FIG. 2, the cleaning tank 2 includes a discharge port 2b provided at the rear and upper part of one side wall 2a and communicating with the inside of the cleaning tank 2, an exhaust port 15 provided at the upper part of the front surface 2c, and the side wall 2a. Provided with a ventilation path 14 communicating with the exhaust port 2b and the exhaust port 15, and the steam in the cleaning tank 2 is discharged to the outside through the exhaust port 2b, the blower channel 14, and the exhaust port 15. It is like that.

送風経路14は、図3に示すように、途中で第1送風経路14aと、第2送風経路14bの複数の送風経路に分岐しており、一方の第1送風経路14aには除湿機能手段となる調湿性能樹脂16が取り付けてあり、他方の第2送風経路14bには、風圧の差によって開閉可能な弁機構17が設けてある。   As shown in FIG. 3, the air supply path 14 is branched into a plurality of air supply paths of the first air supply path 14a and the second air supply path 14b in the middle, and one of the first air supply paths 14a includes dehumidifying function means. The second air flow path 14b is provided with a valve mechanism 17 that can be opened and closed by a difference in wind pressure.

上記構成における食器洗い機の動作、作用を説明する。   The operation and action of the dishwasher in the above configuration will be described.

高温の加熱すすぎで洗浄槽2内が暖められ、洗浄槽2内の水分が大量の蒸気に変えられる。更に乾燥行程において、乾燥ファン7により洗浄槽2内に送り込まれた風が、洗浄槽2の底面部に取り付けられたヒータ(図示せず)を通過する際に暖められる。暖められた空気は、被洗浄物10や洗浄槽2内に付着した水滴に熱を与え、その水分を蒸発させ、さらに多くの蒸気を洗浄槽2内に発生させる。   The inside of the washing tank 2 is warmed by the high temperature heating rinse, and the moisture in the washing tank 2 is changed to a large amount of steam. Further, in the drying process, the wind sent into the cleaning tank 2 by the drying fan 7 is warmed when passing through a heater (not shown) attached to the bottom surface of the cleaning tank 2. The warmed air gives heat to the object to be cleaned 10 and water droplets adhering in the cleaning tank 2, evaporates the water, and generates more vapor in the cleaning tank 2.

発生する蒸気の多い乾燥初期は乾燥ファン7の風量を落とすことにより、弁機構17が自重により、第2送風経路14bを閉じている。そして、発生した洗浄槽2内の蒸気は、排出口2bを通して洗浄槽2から送風経路14へ送られ、分岐した第1送風経路14aに流入し調湿性能樹脂16を通過することにより、空気中の水分が吸収され、乾燥空気として排気口15より排出される。   In the initial stage of drying when much steam is generated, the air flow of the drying fan 7 is reduced, and the valve mechanism 17 closes the second air passage 14b by its own weight. And the generated vapor | steam in the washing tank 2 is sent to the ventilation path 14 from the washing tank 2 through the discharge port 2b, flows into the branched 1st ventilation path 14a, passes through the humidity control resin 16, and is in the air. Are absorbed and discharged as dry air from the exhaust port 15.

また、洗浄槽2内の蒸気量が少なくなってくる頃に乾燥ファン7の風圧を大きくすることにより、第2送風経路14bに取り付けられた弁機構17の前後で大きな風圧差が生じ、その結果自重により閉じていた弁機構17が風圧に応じた大きさで開き、大風量の排気が、第2送風経路14bを経て排気口15より排出されるようになる。そのため、洗浄槽2内の蒸気を排出するのに乾燥時間を延長することなく、蒸気を排出することが可能となり、乾燥性能を確保することができる。   Further, by increasing the wind pressure of the drying fan 7 when the amount of steam in the cleaning tank 2 decreases, a large wind pressure difference occurs between the front and rear of the valve mechanism 17 attached to the second air passage 14b. The valve mechanism 17 closed by its own weight opens with a size corresponding to the wind pressure, and a large amount of exhaust is discharged from the exhaust port 15 via the second air passage 14b. Therefore, it is possible to discharge the steam without extending the drying time for discharging the steam in the cleaning tank 2, and it is possible to ensure the drying performance.

以上のように、本実施の形態においては、送風経路14の途中が分岐しており、一方の第1送風経路14aには調湿性能樹脂16が取り付けてあり、他方の第2送風経路14bには、風圧に応じて開閉する弁機構17を設けたことにより、乾燥ファン7の風圧によって、送風経路14の分岐経路を選択し送風することができ、乾燥初期の蒸気が大量に発生するときは、風圧を低くして、乾燥空気を少なく排出し、乾燥行程の初期段階が過ぎてから、風圧を高くし、蒸気を多量に排出することができるように、乾燥速度および排気空気の湿度をコントロールすることができるために、蒸気による周辺物への被害や台所内が高温多湿になるといったことを防止することができる。   As described above, in the present embodiment, the middle of the air blowing path 14 is branched, the humidity control resin 16 is attached to one first air blowing path 14a, and the other second air blowing path 14b is attached. Is provided with a valve mechanism 17 that opens and closes according to the wind pressure, so that the branch path of the blowing path 14 can be selected and blown by the wind pressure of the drying fan 7, and when a large amount of steam in the initial stage of drying is generated Control the drying speed and the humidity of the exhaust air so that the wind pressure can be lowered and less dry air can be discharged, and after the initial stage of the drying process has passed, the wind pressure can be increased and a large amount of steam can be discharged. Therefore, it is possible to prevent damage to surrounding objects due to steam and the inside of the kitchen becoming hot and humid.

以上のように、本発明にかかる食器洗い機は、ソレノイドやギヤードモータといった高価な電装部品を使用することなく、安価な構成で、風圧差により弁機構を開閉させて、送風経路を切り替えて排出する蒸気量の調節ができるため、蒸気による周辺物への被害や台所内が高温多湿になるといったことを防止することができるもので、食器洗い機に限らず、調理機器、衣類乾燥機、厨芥乾燥機など蒸気を排出する各種機器に広く適用できるものである。   As described above, the dishwasher according to the present invention does not use expensive electrical components such as solenoids and geared motors, and opens and closes the valve mechanism according to the wind pressure difference, and discharges by switching the ventilation path with an inexpensive configuration. Because the amount of steam can be adjusted, it can prevent damage to surroundings due to steam and the inside of the kitchen becoming hot and humid. Not only dishwashers but also cooking equipment, clothes dryers, and basket dryers It can be widely applied to various devices that discharge steam.
