JP 2001-46301 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、システムキッチンに収容された状態で、洗浄槽２内の空気を外部に排出するためには、洗浄槽２の前方に排気口９を配置する必要がある。また、排気口９から排出される洗浄槽２内の空気は、洗浄槽２内の温度とほぼ同じ（約８０℃）であり、場合によってはやけどの恐れがあるという課題を有していた。 However, in the configuration of such a conventional dishwasher, it is necessary to arrange the exhaust port 9 in front of the washing tub 2 in order to discharge the air in the washing tub 2 to the outside while being housed in the system kitchen. There is. Further, the air in the cleaning tank 2 discharged from the exhaust port 9 is substantially the same as the temperature in the cleaning tank 2 (about 80 ° C.), and there is a problem that there is a risk of burns in some cases.

また、乾燥工程の初期には、特に水分を多く含んだ空気が排出されるため、体感温度が高くやけどになりやすいと共に、外気との温度差で機外への結露の原因になるという課題を有していた。 In addition, air that contains a lot of moisture is discharged at the initial stage of the drying process, so the temperature of the body is high and it tends to cause burns, and the temperature difference from the outside air causes condensation outside the machine. Had.

また、洗浄・すすぎ工程において、洗浄水温が高いとき（約５０℃）、洗浄水の蒸気が排気口９から漏出し、排気口９を配置している前面パネル８に結露するという課題を有していた。 Further, in the cleaning / rinsing process, when the cleaning water temperature is high (about 50 ° C.), the cleaning water vapor leaks from the exhaust port 9 and condenses on the front panel 8 in which the exhaust port 9 is disposed. It was.

また、排気口９に外気が混入するように構成した場合、送風手段１０により排出される洗浄槽２内の空気の量と混入させる外気の量を調節することができないため、乾燥工程初期の水分の多い空気の温度を下げるためには、洗浄槽２内の空気に対し、多量の外気が必要になり、外気の量を多くするか洗浄槽２内の空気の排出量を減らすことになる。外気の量を必要以上に多くするには、送風手段１０の能力を高くする必要があり、その結果大きなものとなり、限られたスペースにできるだけ多くの食器類４を収納するためには非常に無駄であった。 In addition, when the outside air is mixed in the exhaust port 9, the amount of air in the cleaning tank 2 discharged by the blowing means 10 and the amount of outside air to be mixed cannot be adjusted. In order to lower the temperature of the air having a large amount of air, a large amount of outside air is required with respect to the air in the washing tank 2, and the amount of outside air is increased or the amount of air discharged in the washing tank 2 is reduced. In order to increase the amount of outside air more than necessary, it is necessary to increase the capacity of the air blowing means 10, and as a result, the capacity becomes large, and it is very wasteful to store as much tableware 4 as possible in a limited space. Met.

また、洗浄槽２内の空気の排出量を減らすことは、洗浄槽２内の水分を排出するのに時間が余計にかかり、結果的に乾燥工程が長くなるという課題を有していた。 In addition, reducing the amount of air discharged from the cleaning tank 2 has a problem that it takes time to discharge the water in the cleaning tank 2, resulting in a longer drying process.

本発明は、上記従来の課題を解決するもので、食器の乾燥性能を低下させることなく、容易に排気口から排出される洗浄槽内の空気の温度を低くしつつ、湿度を下げて、加熱空気によるやけどや機外への結露を防止することができる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-described conventional problems, and without reducing the drying performance of the tableware, while reducing the temperature of the air in the cleaning tank easily discharged from the exhaust port, lowering the humidity and heating An object of the present invention is to provide a dishwasher that can prevent air burns and condensation outside the machine.

（実施の形態１）
図１は、本発明の第１の実施の形態における食器洗い機の断面図である。 (Embodiment 1)
FIG. 1 is a cross-sectional view of the dishwasher according to the first embodiment of the present invention.

図１において、１５は、システムキッチンに収容された食器洗い機本体で、食器洗い機本体１５の内部に設けた洗浄槽１６は、上方に開口部１７を有し、食器類１８を収容する食器かご１９を配置している。食器かご１９の下方には、洗浄水を噴射する洗浄ノズル２０が回転自在に設けられている。２１は、洗浄槽１６内に溜めた洗浄水を、洗浄ノズル２０に送り、洗浄ノズル２０から噴出させながら、洗浄槽１６内で循環させるポンプである。また、底部には、洗浄水および第１の送風手段２２によって送風される空気とを加熱するヒータ２３が配設されている。 In FIG. 1, reference numeral 15 denotes a dishwasher main body accommodated in the system kitchen. A washing tub 16 provided inside the dishwasher main body 15 has an opening 17 on the upper side, and a tableware basket 19 for accommodating tableware 18. Is arranged. A cleaning nozzle 20 that jets cleaning water is rotatably provided below the tableware basket 19. A pump 21 circulates the cleaning water stored in the cleaning tank 16 in the cleaning tank 16 while sending the cleaning water to the cleaning nozzle 20 and ejecting the cleaning water from the cleaning nozzle 20. In addition, a heater 23 for heating the cleaning water and the air blown by the first blower 22 is disposed at the bottom.

排気口２４は、洗浄槽１６の前方に設けた前面パネル２５と洗浄槽１６との間に配設され、第１の送風手段２２の運転により、洗浄槽１６内の空気が排気口２４より排気されるように構成されている。２６は、前面パネル２５に設けた開口で、排気口２４と開口２６は排気経路２７で連通されている。 The exhaust port 24 is disposed between the front panel 25 provided in front of the cleaning tank 16 and the cleaning tank 16, and the air in the cleaning tank 16 is exhausted from the exhaust port 24 by the operation of the first blowing means 22. It is configured to be. Reference numeral 26 denotes an opening provided in the front panel 25, and the exhaust port 24 and the opening 26 communicate with each other through an exhaust path 27.

第２の送風手段２８は、第１の送風手段２２とほぼ同じ能力を有し、外気を、前面パネル２５の後方に配設した送風経路２９に連通させ、開口２６に送風するように構成され、送風経路２９は、排気経路２７と前後方向で面接触するように配設されつつ、開口２６で、洗浄槽１６内から排出された空気と、外気が混合するように構成されている。 The second blower means 28 has substantially the same capacity as the first blower means 22 and is configured to communicate outside air to a blower path 29 disposed behind the front panel 25 and blow the air to the opening 26. The air passage 29 is arranged so as to be in surface contact with the exhaust passage 27 in the front-rear direction, and is configured so that the air discharged from the cleaning tank 16 and the outside air are mixed in the opening 26.

また、洗浄槽１６の下部には、洗浄水あるいは洗浄槽１６の温度を検知する温度検知手段３０を設け、洗浄・すすぎ・乾燥工程を逐次制御する制御手段３１は、温度検知手段３０からの信号によって、第１の送風手段２２、第２の送風手段２８の運転時間を制御するように構成され、洗浄・すすぎ工程で、温度検知手段３０が一定の温度（例えば５０℃）を検知すると第２の送風手段２８の運転が開始し、乾燥工程に入ると、第２の送風手段２８を運転すると共に、第１の送風手段２２を数分間間欠運転させた後、連続運転させ、一定の時間経過後に、第２の送風手段２８を間欠運転をするようにしている。 A temperature detection means 30 for detecting the temperature of the cleaning water or the cleaning tank 16 is provided at the lower part of the cleaning tank 16, and the control means 31 for sequentially controlling the cleaning, rinsing and drying processes is a signal from the temperature detection means 30. Is configured to control the operating time of the first air blowing means 22 and the second air blowing means 28, and the second when the temperature detecting means 30 detects a certain temperature (for example, 50 ° C.) in the cleaning / rinsing process. When the operation of the air blowing means 28 is started and the drying process is started, the second air blowing means 28 is operated, and the first air blowing means 22 is intermittently operated for several minutes and then continuously operated for a certain time. Later, the second air blowing means 28 is intermittently operated.

また、洗浄槽１６の両側面には、第１のレール３２が固定され、第１のレール３２は、食器洗い機本体１５に固定した第２のレール３３によって前後方向へ平行移動可能に支持されている。食器類１８の出し入れを行う際には、前面パネル２５に設けられたハンドル３４をつかみ、洗浄槽１６を前方に引き出し、上方の開口部１７より食器類１８の収容を行う。 Moreover, the 1st rail 32 is fixed to the both sides | surfaces of the washing tank 16, and the 1st rail 32 is supported by the 2nd rail 33 fixed to the dishwasher main body 15 so that a parallel movement is possible in the front-back direction. Yes. When the tableware 18 is put in and out, the handle 34 provided on the front panel 25 is grasped, the washing tank 16 is pulled forward, and the tableware 18 is accommodated from the upper opening 17.

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

まず、使用者が、前面パネル２５に設けたハンドル３４をつかみ洗浄槽１６を食器洗い機本体１５から引き出し、洗浄槽１６内に配置した食器かご１９に汚れた食器類１８をセットする。次に洗浄槽１６を食器洗い機本体１５内に戻し、運転を開始すると、洗浄槽１６の内底に配置されたヒータ２３によって洗浄水が加熱され、その加熱された洗浄水が洗浄ノズル２０から食器類１８に向かって噴射され、食器類１８の汚れを落とす洗浄工程が行われる。その後、数回の溜めすすぎを行った後、ヒータ２３によって約８０℃に加熱しながらすすぐ、加熱すすぎ工程を行った後、食器類１８および洗浄槽１６内部を乾かす乾燥工程に移行する。 First, the user grasps the handle 34 provided on the front panel 25 and pulls out the washing tub 16 from the dishwasher main body 15, and sets the dirty dishes 18 in the dish basket 19 disposed in the washing tub 16. Next, when the washing tub 16 is returned to the dishwasher main body 15 and the operation is started, the washing water is heated by the heater 23 disposed on the inner bottom of the washing tub 16, and the heated washing water is supplied from the washing nozzle 20 to the tableware. A cleaning process is performed to spray the dishes 18 and remove the stains on the dishes 18. Thereafter, after rinsing several times, the heater 23 is rinsed while being heated to about 80 ° C., and the heating rinsing process is performed. Then, the process proceeds to a drying process in which the tableware 18 and the washing tank 16 are dried.

乾燥工程では、ヒータ２３によって洗浄槽１６内の空気を加熱しながら、第１の送風手段２２によって、水分を多く含むと共に高温の加熱空気が排気口２４より排出され、その排気口２４から排出された空気は、開口２６で、第２の送風手段２８により送られてきた外気と合流し、温度、湿度が低減されて、外部に排出される。乾燥工程が終了すると食器洗い機本体１５の全ての運転が終了する。 In the drying process, while the air in the cleaning tank 16 is heated by the heater 23, the first blowing unit 22 contains a large amount of water and high-temperature heated air is discharged from the exhaust port 24, and is discharged from the exhaust port 24. The air merges with the outside air sent by the second air blowing means 28 through the opening 26, and the temperature and humidity are reduced, and the air is discharged to the outside. When the drying process is finished, all the operations of the dishwasher body 15 are finished.

乾燥工程の初期は、特に水分を多く含んだ加熱空気が排気口２４から排出されるが、ここで、第２の送風手段２８を運転すると共に、第１の送風手段２２を数分間間欠運転することにより、容易に第１の送風手段２２の風量を落とすことができるため、間欠運転後の送風量は従来のまま乾燥工程を続けることが可能になり、食器類１８の乾燥性能を低下させることなく、容易に排気口２４から排出される洗浄槽１６内の空気の温度を下げるとともに、排気される空気中の水分を減少させることで、加熱空気によるやけどや機外への結露を防止することができる。 In the initial stage of the drying process, heated air containing a large amount of moisture is discharged from the exhaust port 24. Here, the second blower means 28 is operated and the first blower means 22 is intermittently operated for several minutes. Thus, since the air volume of the first air blowing means 22 can be easily reduced, the air volume after the intermittent operation can continue the drying process as before, and the drying performance of the tableware 18 is lowered. In addition, the temperature of the air in the cleaning tank 16 that is easily discharged from the exhaust port 24 is lowered, and the moisture in the exhausted air is reduced to prevent burns and dew condensation outside the machine due to heated air. Can do.

また、加熱すすぎ工程など、洗浄水が高温になる場合、洗浄水の蒸気が排気口２４より漏出するが、温度検知手段３０によって、洗浄槽１６が一定の温度（例えば５０℃）になったことを検知すると第２の送風手段２８を運転するようにしたことにより、排気される空気中の水分が減り、前面パネル２５に結露するのを防止することができる。 Further, when the cleaning water becomes hot, such as a heating rinse process, the cleaning water vapor leaks from the exhaust port 24, but the temperature detection means 30 causes the cleaning tank 16 to reach a certain temperature (for example, 50 ° C.). When the second air blowing means 28 is operated, the moisture in the exhausted air is reduced, and condensation on the front panel 25 can be prevented.

また、乾燥工程時に、洗浄槽１６内の温度低下に伴って第１の送風手段２２の風量を多くすることにより、乾燥工程初期の、高い温度の空気の排気量を少なくして、機外への排気温度を低くするとともに、洗浄槽１６内の温度が下がるに従って、従来の排気量に戻すことで、食器類１８の乾燥性能を確保することができる。 Further, by increasing the air volume of the first air blowing means 22 as the temperature in the cleaning tank 16 decreases during the drying process, the amount of high-temperature air exhausted at the initial stage of the drying process is reduced, and the outside of the apparatus is removed. As the temperature in the cleaning tank 16 is lowered, the drying performance of the dishes 18 can be ensured by returning to the conventional exhaust amount.

また、乾燥工程時に、洗浄槽１６内の温度低下に伴って第２の送風手段２８の風量を少なくするようにすれば、乾燥工程初期の温度の高い時、外部からの空気の風量を多くして排気温度を低くするとともに、洗浄槽１６内の温度が下がった状態では、空気が必要以上に開口２６から排気されないようにすることができる。 Further, if the air volume of the second blower means 28 is reduced in accordance with the temperature drop in the cleaning tank 16 during the drying process, the air volume from the outside is increased when the temperature in the initial stage of the drying process is high. Thus, while the exhaust temperature is lowered, the air can be prevented from being exhausted from the opening 26 more than necessary when the temperature in the cleaning tank 16 is lowered.

このように本実施の形態によれば、食器の乾燥性能を低下させることなく、容易に排気口から排出される洗浄槽１６内の空気の温度を低くしつつ、湿度を下げることで、加熱空気によるやけどや機外への結露を防止することができる。 As described above, according to the present embodiment, the heating air is reduced by lowering the humidity while lowering the temperature of the air in the cleaning tank 16 easily discharged from the exhaust port without deteriorating the drying performance of the tableware. Can prevent burns and condensation outside the machine.

また、洗浄槽１６内の温度が上昇してきて一定の温度に達した時に、第２の送風手段２８を運転させ、送風経路２９に外気を通すことにより、洗浄・すすぎ工程で高温になる洗浄水の蒸気が排気口２４より漏出し、前面パネル２５に結露するのを防止することができる。 Further, when the temperature in the cleaning tank 16 rises and reaches a certain temperature, the second air blowing means 28 is operated and the outside air is passed through the air blowing path 29, so that the cleaning water becomes high in the cleaning / rinsing process. Can be prevented from leaking from the exhaust port 24 and condensing on the front panel 25.

また、乾燥工程の初期において、第１の送風手段２２による排気経路２７の風量を第２の送風手段２８による送風経路２９のそれより少なくすれば、乾燥工程初期の温度の高い空気の排気量が減り、機外に排気される空気の温度が下がると共に、洗浄槽１６内の温度が下がった時に、従来の排気量に戻すようにすれば、食器類１８の乾燥性能を確保することができる。 Further, if the air volume in the exhaust passage 27 by the first air blowing means 22 is made smaller than that in the air flow path 29 by the second air blowing means 28 at the initial stage of the drying process, the amount of air discharged at a high temperature in the initial stage of the drying process can be increased. If the temperature of the air exhausted to the outside of the apparatus decreases and the temperature in the washing tank 16 decreases, it is possible to ensure the drying performance of the dishes 18 by returning to the conventional exhaust amount.

また、乾燥工程時に、洗浄槽１６内の温度低下に伴って第１の送風手段２２による排気経路２７の風量を多くすることにより、乾燥工程初期の高い温度の空気の排気量を少なくし、機外への排気温度を低くするとともに、洗浄槽１６内の温度が下がるに従って従来の排気量に戻すことで、食器類の乾燥性能を確保することができる。 Further, during the drying process, by increasing the air volume of the exhaust passage 27 by the first blower means 22 as the temperature in the cleaning tank 16 decreases, the exhaust volume of high-temperature air at the initial stage of the drying process is reduced. It is possible to ensure the drying performance of the dishes by lowering the exhaust temperature to the outside and returning to the conventional exhaust amount as the temperature in the cleaning tank 16 decreases.

また、乾燥工程時に、洗浄槽１６内の温度低下に伴って第２の送風手段２８による送風経路２９の風量を少なくすることにより、乾燥工程初期の温度の高い時、機外からの風量を多くして排気温度を低くするとともに、洗浄槽１６内の温度が下がった状態で、必要以上に空気が開口２６から排気されないようにすることができる。 Further, during the drying process, the amount of air from outside the apparatus is increased when the temperature in the initial stage of the drying process is high by reducing the air volume of the air passage 29 by the second air blowing means 28 as the temperature in the cleaning tank 16 decreases. Thus, the exhaust temperature can be lowered and the air can be prevented from being exhausted from the opening 26 more than necessary in the state where the temperature in the cleaning tank 16 is lowered.

また、乾燥工程時に、洗浄槽１６内の温度低下に伴って第１の送風手段２２による排気経路２７の風量を多くしつつ、第２の送風手段２８による送風経路２９の風量を少なくすることにより、乾燥工程初期の、高い温度の排気量を少なくしつつ、外気の風量を多くすることで、より排気温度を下げ、洗浄槽１６内の温度が下がった状態では、排気量を従来の風量と同じにして、食器類１８の乾燥性能を確保するとともに、必要以上に空気が開口２６から排気されないようにすることができる。 Further, during the drying process, by increasing the air volume of the exhaust passage 27 by the first blower means 22 and decreasing the air volume of the blower path 29 by the second blower means 28 as the temperature in the cleaning tank 16 decreases. In the initial stage of the drying process, the amount of exhaust air at a high temperature is reduced while the amount of outside air is increased so that the exhaust temperature is lowered and the temperature in the cleaning tank 16 is lowered. In the same manner, the drying performance of the tableware 18 can be ensured, and air can be prevented from being exhausted from the opening 26 more than necessary.

また、洗浄槽１６は、食器洗い機本体１５に対し引き出し自在に設けたもので、システムキッチンに収容された食器洗い機本体１５の洗浄槽１６の前部から機外に排出される空気の温度を低くし、かつ湿度を下げることができるので、使用者の安全を確保できるとともに、機外への結露を確実に防止することができ、使用感を向上させた食器洗い機を提供することができる。 The washing tub 16 is provided so as to be freely drawn out from the dishwasher main body 15. The temperature of the air discharged from the front of the washing tub 16 of the dishwasher main body 15 accommodated in the system kitchen is lowered. In addition, since the humidity can be lowered, it is possible to provide a dishwasher that can ensure the safety of the user and can reliably prevent dew condensation outside the machine and improve the feeling of use.

なお、上記実施の形態では、第１の送風手段２２、第２の送風手段２８による排気経路２７、送風経路２９の風量を、連続運転と間欠運転とで、すなわち運転時間で変えるようにしたが、いずれも連続運転しながら、回転数を変えて、風量を変えるようにしても良い。 In the above embodiment, the air volume of the exhaust passage 27 and the air passage 29 by the first air blowing means 22 and the second air blowing means 28 is changed between continuous operation and intermittent operation, that is, depending on the operation time. In either case, the air volume may be changed by changing the rotation speed while continuously operating.

以上のように本発明に係る食器洗い機は、食器の乾燥性能を低下させることなく、外部に排出される洗浄槽内の空気の温度を低くしつつ、湿度を下げることで、加熱空気によるやけどや機外への結露を防止することができるもので、家庭用、業務用の食器洗い機に広く適用できる。 As described above, the dishwasher according to the present invention is burned by heated air by lowering the humidity while lowering the temperature of the air in the washing tank discharged outside without lowering the drying performance of the tableware. It can prevent condensation outside the machine and can be widely applied to household and commercial dishwashers.
