【産業上の利用分野】[Industrial applications]

本考案は食器洗浄機、特に、昇温した洗浄水，すすぎ水を噴射して洗浄，すす ぎを行う食器洗浄機に関する。 The present invention relates to a dishwasher, and more particularly to a dishwasher that sprays heated washing water and rinsing water to wash and rinse.

【従来の技術と考案が解決しようとする課題】[Problems to be solved by conventional techniques and devices]

一般に、食器洗浄機は、洗浄槽内に収納した食器に洗浄水，すすぎ水をノズル から噴射して洗浄，すすぎを行い、さらに、回収した前記洗浄水を循環させて食 器に再度噴射して洗浄等を行うものである。ところで、洗浄水，すすぎ水の温度 が高いと、洗浄，すすぎ効果が向上するので、洗浄等に要する処理時間が短くな る。このため、従来の食器洗浄機では、例えば、前記洗浄槽内の底部にヒータを 配置し、洗浄槽に満量の洗浄水を注入した後、食器に洗浄水を洗浄ノズルから噴 射すると同時に、前記ヒータで洗浄水を加熱していた。 Generally, a dishwasher performs cleaning and rinsing by injecting washing water and rinsing water from nozzles into the dishes stored in the washing tub, and then circulating the collected washing water and re-injecting it into the eating device. It is for cleaning and the like. By the way, if the temperature of washing water and rinsing water is high, the washing and rinsing effect is improved, and the processing time required for washing and the like is shortened. For this reason, in a conventional dishwasher, for example, a heater is arranged at the bottom of the washing tank, and after pouring a large amount of washing water into the washing tank, the washing water is sprayed from the washing nozzle at the same time. The cleaning water was heated by the heater.

【０００３】 しかしながら、前述の方法では、初期温度の低い洗浄水が所望の洗浄効果が得 られる温度に達するまでに時間がかかるので、早期に所望の洗浄効果が得られな い。このため、初期温度が低い満量の洗浄水等を注入した後、加熱しながら洗浄 等を行う食器洗浄機も提案されているが、この食器洗浄機では、洗浄時間，すす ぎ時間を効果的に短縮できないという問題点がある。However, in the above-mentioned method, since it takes time for the cleaning water having a low initial temperature to reach the temperature at which the desired cleaning effect is obtained, the desired cleaning effect cannot be obtained early. For this reason, a dishwasher has been proposed in which a full amount of washing water with a low initial temperature is injected and then washing is performed while heating. However, in this dishwasher, the washing time and rinsing time are effective. There is a problem that it cannot be shortened to.

【０００４】 そこで、本考案は、前記問題点に鑑み、総合処理時間を効果的に短縮できる食 器洗浄機を提供することを目的とする。In view of the above problems, it is an object of the present invention to provide a dishwasher that can effectively reduce the total processing time.

【実施例】【Example】

次に、本考案にかかる食器洗浄機の一実施例を図１ないし図６の添付図面を参 照して説明する。 本実施例にかかる食器洗浄機は、図１に示すように、洗浄機本体１０の洗浄槽 １１内に食器１２を収納した収納かご１３が配置され、そして、この収納かご１ ３の下方側に、前記食器１２に洗浄水，すすぎ水を回転しながら噴射するノズル １４が設けられている。このノズル１４は、洗浄機本体１０の底面を貫通する吐 出管１５を介し、モータ１６によって駆動されるポンプ１７に接続されている。 さらに、前記洗浄機本体１０の底面には前記ノズル１４から噴射された洗浄水等 を回収するための水溜め部１８が設けられ、この水溜め部１８は第１切替弁１９ を介して前記ポンプ１７に接続され、循環流路が形成可能となっている。また、 前記第１切替弁１９は、ヒータ２０を内蔵する昇温部２１を介して給水口２２に 接続されているとともに、中継管２３を介して前記給水口２２に接続され、循環 流路が形成可能となっている。そして、前記給水口２２と中継管２３との間には 、昇温部２１または中継管２３に選択的に切り替え可能な第２切替弁２４が設け られている。さらに、前記昇温部２１は開閉弁２５を介して高温すすぎ用のすす ぎ水を溜めておく予備タンク２６に接続されている一方、前記水溜め部１８は排 水ポンプ２７を介して排水口２８に接続されている。 Next, an embodiment of the dishwasher according to the present invention will be described with reference to the accompanying drawings of FIGS. 1 to 6. In the dishwasher according to the present embodiment, as shown in FIG. 1, a storage basket 13 storing the dishes 12 is arranged in a cleaning tank 11 of the main body 10 of the washing machine, and a storage basket 13 is provided below the storage basket 13. The tableware 12 is provided with a nozzle 14 for spraying washing water and rinsing water while rotating. The nozzle 14 is connected to a pump 17 driven by a motor 16 via a discharge pipe 15 penetrating the bottom surface of the cleaner body 10. Further, a water reservoir 18 for collecting cleaning water or the like sprayed from the nozzle 14 is provided on the bottom surface of the washer body 10, and the water reservoir 18 is connected to the pump via a first switching valve 19. It is connected to 17 and a circulation channel can be formed. Further, the first switching valve 19 is connected to the water supply port 22 via a temperature raising section 21 having a heater 20 built therein, and is also connected to the water supply port 22 via a relay pipe 23 so that a circulation flow path is formed. It can be formed. A second switching valve 24 is provided between the water supply port 22 and the relay pipe 23 so as to selectively switch between the temperature raising unit 21 and the relay pipe 23. Further, the temperature raising section 21 is connected via an opening / closing valve 25 to a backup tank 26 for storing high-temperature rinsing water, while the water holding section 18 is connected via a drainage pump 27 to a drainage port. 28 is connected.

【００１０】 次に、前述の構成からなる食器洗浄機の処理工程である高温洗浄工程、常温す すぎ工程、および、高温すすぎ工程を順次説明する。Next, the high temperature cleaning step, the room temperature rinsing step, and the high temperature rinsing step, which are the processing steps of the dishwasher having the above-described configuration, will be sequentially described.

【００１１】 高温洗浄工程は食器の汚れを洗い落とす最初の処理工程であり、図１に示すよ うに、第１切替弁１９が水溜め部１８と昇温部２１とを連通状態にするとともに 、ポンプ１７と中継管２３とを連通状態にしている。そして、第２切替弁２４が 給水口２２と昇温部２１とを連通状態にするとともに、給水口２２と中継管２３ とを閉状態にしている。このとき、開閉弁２５は高温すすぎ水用の予備タンク２ ６を閉じている。The high-temperature washing step is the first processing step for washing off the stains on the dishes, and as shown in FIG. 1, the first switching valve 19 brings the water storage section 18 and the temperature raising section 21 into communication with each other, and 17 and the relay pipe 23 are in communication with each other. Then, the second switching valve 24 makes the water supply port 22 and the temperature raising unit 21 communicate with each other, and makes the water supply port 22 and the relay pipe 23 closed. At this time, the on-off valve 25 closes the reserve tank 26 for hot rinse water.

【００１２】 このため、給水口２２から流入した洗浄水は昇温部２１のヒータ２０で加熱さ れ、昇温して水溜め部１８から洗浄槽１１内に流入する。そして、所定量の洗浄 水が洗浄槽１１内に溜められると、第２切替弁２４が切り替わり、給水口２２と 、昇温部２１および中継管２３とを閉状態にし、昇温部２１と中継管２３とを連 通状態にして循環流路を形成する（図２）。ついで、予備昇温した洗浄水をポン プ１７および吐出管１５を介してノズル１４から食器１２に噴射して洗浄した後 、水溜め部１８に回収した洗浄水を昇温部２１のヒータ２０で加熱し、中継管２ ３を介してポンプ１７に戻し、吐出管１５を介してノズル１４から再び噴射し、 この操作を繰り返す。そして、所望の洗浄効果が得られる温度に洗浄水が達した 後、第１切替弁１９を切り替えて水溜め部１８とポンプ１７とを連通状態にし（ 図３）、ポンプ１７，吐出口１５，ノズル１４、洗浄槽１１および水溜め部１８ の順に所定の温度に達した洗浄水を循環させて高温洗浄を行う。Therefore, the cleaning water that has flowed in from the water supply port 22 is heated by the heater 20 of the temperature raising unit 21, rises in temperature, and flows into the cleaning tank 11 from the water reservoir 18. Then, when a predetermined amount of cleaning water is stored in the cleaning tank 11, the second switching valve 24 is switched, the water supply port 22, the temperature raising unit 21 and the relay pipe 23 are closed, and the temperature raising unit 21 is relayed. The pipe 23 is connected to form a circulation flow path (FIG. 2). Then, the preheated cleaning water is sprayed from the nozzle 14 to the dishes 12 through the pump 17 and the discharge pipe 15 to clean the cleaning water, and the cleaning water collected in the water reservoir 18 is then heated by the heater 20 of the temperature raising unit 21. It is heated and returned to the pump 17 via the relay pipe 23, is again jetted from the nozzle 14 via the discharge pipe 15, and this operation is repeated. Then, after the cleaning water reaches a temperature at which a desired cleaning effect is obtained, the first switching valve 19 is switched to make the water reservoir 18 and the pump 17 communicate with each other (FIG. 3), and the pump 17, the discharge port 15, High-temperature cleaning is performed by circulating cleaning water that has reached a predetermined temperature in the order of the nozzle 14, the cleaning tank 11, and the water reservoir 18.

【００１３】 この高温洗浄工程では、従来例のように洗浄槽１１に満量の洗浄水を注入した 後、洗浄処理と同時に加熱するのではなく、洗浄槽１１に洗浄水を注入する際に 洗浄水をヒータ２０で予備加熱するので、洗浄水の初期温度が従来例よりも高い 。このため、当初から温度の高い洗浄水で洗浄できるだけでなく、所望の洗浄効 果が得られる温度に従来例よりも早く洗浄水が達するので、高温洗浄工程の処理 時間を短縮できるという利点がある。In this high temperature cleaning step, instead of heating the cleaning tank 11 at the same time as in the conventional example after injecting a large amount of cleaning water into the cleaning tank 11, the cleaning tank 11 is cleaned when the cleaning water is injected. Since the water is preheated by the heater 20, the initial temperature of the washing water is higher than that of the conventional example. Therefore, not only can it be washed with high-temperature washing water from the beginning, but the washing water reaches the temperature at which the desired washing effect can be obtained earlier than in the conventional example, which has the advantage of shortening the processing time of the high-temperature washing process. .

【００１４】 一方、所定の温度に達した洗浄水で洗浄処理が行われている間、第２切替弁２ ４が切り替わって給水口２２と昇温部２１とが連通状態になるとともに、開閉弁 ２５が開いて昇温部２１と予備タンク２６とが連通状態になる（図４）。そして 、洗浄槽１１に注入して使用される高温すすぎ用のすすぎ水のうち、その満量の １０分の１のすすぎ水が給水口２２から昇温部２１に流入し、昇温部２１のヒー タ２０で予備加熱されたすすぎ水が新たに流入するすすぎ水の水圧で押し上げら れて予備タンク２６に流入した後、第２切替弁２４が切り替わり（図５）、昇温 部２１に新たに流入したすすぎ水がヒータ２０で加熱される。ついで、新たに流 入したすすぎ水が所定の温度に達すると、第２切替弁２４が切り替わり、前述と 同様、給水口２２から昇温部２１に高温すすぎ用のすすぎ水が満量の１０分の１ だけ新たに注入され、昇温したすすぎ水が予備タンク２６内に溜められる。以後 、同様な操作が高温洗浄工程の間に計７回行われ、予備加熱で昇温した満量の７ ０％のすすぎ水が予備タンク２６に溜められる。On the other hand, while the cleaning process is being performed with the cleaning water that has reached the predetermined temperature, the second switching valve 24 is switched so that the water supply port 22 and the temperature raising unit 21 are in communication with each other, and the opening / closing valve is also open. 25 is opened and the temperature raising part 21 and the auxiliary tank 26 are in communication with each other (FIG. 4). Then, of the rinse water for high-temperature rinse that is poured into the cleaning tank 11 and used, one-tenth of the full amount of rinse water flows into the temperature raising section 21 from the water supply port 22, and the temperature raising section 21 After the rinse water preheated by the heater 20 is pushed up by the water pressure of the newly flowing rinse water and flows into the spare tank 26, the second switching valve 24 is switched (Fig. 5), and the temperature raising unit 21 is newly replaced. The rinse water that has flowed into the heater is heated by the heater 20. Then, when the newly introduced rinse water reaches a predetermined temperature, the second switching valve 24 is switched, and similarly to the above, the rinse water for high temperature rinse is supplied from the water supply port 22 to the temperature raising unit 21 for 10 minutes. 1 is newly injected, and the rinse water which has been heated is stored in the auxiliary tank 26. After that, the same operation is performed 7 times in total during the high temperature cleaning step, and the full amount of 70% of the rinse water heated by the preheating is stored in the spare tank 26.

【００１５】 そして、７回目の予備加熱が終了し、第２切替弁２４が切り替わり、給水口２ ２と、昇温部２１および中継管２３とを閉状態にするとともに、開閉弁２５を閉 じた後（図３）、前述の高温洗浄が終了し、水溜め部１８に接続した排水ポンプ ２７を介して排水口２８から洗浄水が排出される。Then, the seventh preheating is completed, the second switching valve 24 is switched, the water supply port 22 and the temperature raising part 21 and the relay pipe 23 are closed, and the on-off valve 25 is closed. After that (FIG. 3), the above-mentioned high temperature cleaning is completed, and the cleaning water is discharged from the drain port 28 via the drain pump 27 connected to the water reservoir 18.

【００１６】 前述の高温洗浄工程が終了した後、常温すすぎ工程が引き続き行われる。 すなわち、高温洗浄工程と同様、第１切替弁１９が切り替わって洗浄槽１１に 設けた水溜め部１８と昇温部２１とを連通状態にし、ポンプ１７と中継管２３と を連通状態にする一方、第２切替弁２４が切り替わって給水口２２と昇温部２１ とを連通状態にする。このとき、開閉弁２５は閉じられている（図１）。このた め、給水口２２から常温すすぎ用のすすぎ水が流入し、昇温部２１のヒータ２０ で加熱されて洗浄槽１１内に溜められる。そして、すすぎ水が満量になると、第 １切替弁１９が切り替わり、ポンプ１７と水溜め部１８とが連通状態になるとと もに、第２切替弁２４が切り替わり、給水口２２と、昇温部２１および中継管２ ３とが閉状態になる（図３）。ついで、ポンプ１７が吐出管１５を介してノズル １４から前記すすぎ水を食器１２に噴射してすすぎ処理を行い、そして、水溜部 １８に回収されたすすぎ水がポンプ１７および吐出管１５を介してノズル１４か ら再び噴射されて循環し、常温すすぎ処理を行う。After the above-described high temperature cleaning process is completed, the room temperature rinsing process is continuously performed. That is, as in the high temperature cleaning step, the first switching valve 19 is switched to bring the water reservoir 18 and the temperature raising portion 21 provided in the washing tank 11 into communication with each other, and the pump 17 and the relay pipe 23 into communication with each other. The second switching valve 24 is switched to bring the water supply port 22 and the temperature raising unit 21 into communication with each other. At this time, the on-off valve 25 is closed (FIG. 1). Therefore, rinse water for rinsing at room temperature flows in from the water supply port 22, is heated by the heater 20 of the temperature raising unit 21, and is stored in the cleaning tank 11. Then, when the rinse water becomes full, the first switching valve 19 is switched, the pump 17 and the water reservoir 18 are brought into communication with each other, the second switching valve 24 is switched, and the water supply port 22 and the temperature rise The part 21 and the relay pipe 23 are closed (FIG. 3). Then, the pump 17 sprays the rinsing water from the nozzle 14 to the dishes 12 through the discharge pipe 15 to perform rinsing treatment, and the rinsing water collected in the water reservoir 18 passes through the pump 17 and the discharge pipe 15. It is jetted again from the nozzle 14 and circulated, and a room temperature rinsing process is performed.

【００１７】 この常温すすぎ工程中に、開閉弁２５が開いて昇温部２１と予備タンク２６と を連通状態にするとともに、第２切替弁２４が切り替わって給水口２２と昇温部 ２１とを連通状態にする（図４）。そして、給水口２２から満量の１０分の１の すすぎ水が昇温部２１に流入し、昇温部２１で予備加熱されて昇温した高温すす ぎ用のすすぎ水が新たに流入するすすぎ水の水圧で予備タンク２６に押し上げら れた後、第２切替弁２４が切り替わる（図５）。ついで、開閉弁２５が閉じられ た後（図３）、第１回目の常温すすぎ工程が終了し、常温すすぎ用のすすぎ水が 水溜め部１８に接続した排水ポンプ２７を介して排水口２８から排出される。常 温すすぎ工程では、前述と同様なすすぎ処理が計３回行われるが、そのすすぎ処 理ごとに、予備加熱で昇温した高温すすぎ用のすすぎ水が予備タンク２６に充填 される。この結果、常温すすぎ工程が終了したとき、予備タンク２６には予備加 熱で昇温した満量の高温すすぎ用のすすぎ水が溜められている。During this normal temperature rinsing process, the on-off valve 25 is opened to bring the temperature raising unit 21 and the auxiliary tank 26 into communication with each other, and the second switching valve 24 is switched to connect the water supply port 22 and the temperature raising unit 21. Make communication (Fig. 4). Then, 1/10 of the full amount of rinse water flows into the temperature raising section 21 from the water supply port 22, and the rinse water for high temperature rinsing which has been preheated in the temperature raising section 21 and has increased in temperature newly flows in. After being pushed up to the spare tank 26 by the water pressure of the water, the second switching valve 24 is switched (Fig. 5). Then, after the on-off valve 25 is closed (FIG. 3), the first normal temperature rinsing step is completed, and the rinsing water for normal temperature rinsing is discharged from the drain port 28 via the drain pump 27 connected to the water reservoir 18. Is discharged. In the normal temperature rinsing step, the same rinsing treatment as described above is performed three times in total, and the rinsing water for high temperature rinsing heated by preheating is filled in the preliminary tank 26 for each rinsing treatment. As a result, when the room temperature rinsing step is completed, the full amount of the rinsing water for high temperature rinsing, which has been heated by the preliminary heating, is stored in the auxiliary tank 26.

【００１８】 この常温すすぎ工程では、洗浄槽１１にすすぎ水を注入する際に昇温部２１で 予備加熱するので、初期温度の高いすすぎ水ですすぎを行うことができ、すすぎ 効率が良いという利点がある。In this room temperature rinsing step, since preheating is performed by the temperature raising unit 21 when rinsing water is injected into the cleaning tank 11, it is possible to perform rinsing with rinsing water having a high initial temperature, which is an advantage of high rinsing efficiency. There is.

【００１９】 高温すすぎ工程では、第１切替弁１９が切り替わって昇温部２１と洗浄槽１１ とを連通状態にし、ポンプ１７と中継管２３とを連通状態にした後、開閉弁２５ が開き（図６）、予備タンク２６に溜めた高温すすぎ用のすすぎ水が流出して洗 浄槽１１内に流入した後、開閉弁２５が閉じられる。そして、ポンプ１７を駆動 して吐出管１５を介してノズル１４からすすぎ水を噴射してすすぎ、水溜め部１ ８に回収したすすぎ水を昇温部２１のヒータ２０で加熱し、中継管２３を介して ポンプ１７に戻して循環させる。そして、すすぎ水が所望のすすぎ効果が得られ る温度に達した後、第１切替弁１９が切り替わって水溜め部１８とポンプ１７と を連通状態にし（図３）、すすぎ水が循環して高温すすぎを続行する。In the high temperature rinsing step, the first switching valve 19 is switched to bring the temperature raising section 21 and the cleaning tank 11 into communication with each other, and the pump 17 and the relay pipe 23 are brought into communication with each other, and then the opening / closing valve 25 is opened ( 6), after the rinsing water for high temperature rinsing stored in the spare tank 26 flows out and flows into the cleaning tank 11, the on-off valve 25 is closed. Then, by driving the pump 17, the rinse water is sprayed from the nozzle 14 through the discharge pipe 15 to rinse, and the rinse water collected in the water reservoir 18 is heated by the heater 20 of the temperature raising unit 21, and the relay pipe 23 It is returned to the pump 17 through and is circulated. Then, after the rinsing water reaches the temperature at which the desired rinsing effect is obtained, the first switching valve 19 switches to bring the water reservoir 18 and the pump 17 into communication (Fig. 3), and the rinsing water circulates. Continue hot rinse.

【００２０】 次いで、高温すすぎ処理が終了すると、第１切替弁１９が切り替わって水溜部 １８と昇温部２１とを連通状態にするとともに、ポンプ１７と中継管２３とを連 通状態にした後（図２）、水溜め部１８に接続した排水ポンプ２７を介してすす ぎ水を排出口２８から排出することにより、一連の処理が終了する。Next, when the high temperature rinsing process is completed, the first switching valve 19 is switched to bring the water reservoir 18 and the temperature raising portion 21 into communication with each other, and after the pump 17 and the relay pipe 23 are brought into communication with each other. (FIG. 2), a series of processes is completed by discharging the soot water from the discharge port 28 via the drainage pump 27 connected to the water reservoir 18.

【００２１】 この高温すすぎ工程では、洗浄槽１１にすすぎ水を注入する場合に、既にヒー タ２０で予備加熱した満量のすすぎ水を使用するので、当初から温度の高いすす ぎ水ですすぎが行えるだけでなく、従来例よりも短い時間で所望のすすぎ効果が 得られる温度にすすぎ水が達し、すすぎ処理時間を節約できるという利点がある 。In this high-temperature rinsing step, when pouring the rinsing water into the cleaning tank 11, the full amount of rinsing water that has been preheated by the heater 20 is used. Not only can it be performed, but the rinsing water reaches the temperature at which the desired rinsing effect can be obtained in a shorter time than the conventional example, and there is an advantage that the rinsing processing time can be saved.

【００２２】 なお、前述の実施例では、水溜め部１８を介して洗浄槽１１に洗浄水を注入し ているが、必ずしもこれに限らず、吐出管１５を介してノズル１４から注入する ように流路を形成してもよい。 また、前述の高温洗浄工程では、７回に分けて高温すすぎ用のすすぎ水を予備 加熱して溜めておく場合について説明したが、必ずしもこれに限らず、例えば、 ヒータの能力や昇温部の大きさを適宜選択することにより、１回で満量の高温す すぎ用のすすぎ水を予備加熱して溜めておいてもよい。 さらに、高温すすぎ用のすすぎ水を予備加熱して溜める操作は高温洗浄工程、 または、常温すすぎ工程だけで完了するようにしてもよい。 そして、洗浄槽の外部に設けた昇温部における一度の加熱で所望の洗浄，すす ぎ効果が得られる温度まで洗浄水等を昇温し、昇温した洗浄水等を洗浄槽内に直 接注入して洗浄，すすぎ処理を行ってもよい。In the above-described embodiment, the cleaning water is injected into the cleaning tank 11 via the water reservoir 18, but not limited to this, the cleaning water may be injected from the nozzle 14 via the discharge pipe 15. A flow path may be formed. Further, in the above-mentioned high temperature cleaning step, the case where the rinsing water for high temperature rinsing is preheated and stored in seven times has been described, but the present invention is not necessarily limited to this. By appropriately selecting the size, a sufficient amount of the rinse water for high temperature rinsing may be preheated and stored once. Further, the operation of preheating and storing the rinse water for high temperature rinsing may be completed only by the high temperature washing step or the room temperature rinsing step.

【考案の効果】[Effect of device]

以上の説明から明らかなように、本考案にかかる請求項１の食器洗浄機によれ ば、昇温部で加熱して昇温した洗浄水，すすぎ水によって食器の洗浄，すすぎを 行うので、最初から高い洗浄，すすぎ効果が得られ、洗浄，すすぎ時間を節約で き、総合処理時間が短い食器洗浄機が得られる。 また、請求項２によれば、洗浄水，すすぎ水を加熱手段で予備加熱しておくの で、当初から高い洗浄，すすぎ効果が得られるだけでなく、所望の洗浄効果が得 られる温度に従来例よりも早く洗浄水等が達する。このため、食器の洗浄，すす ぎ時間を節約でき、前述と同様、総合処理時間の短い食器洗浄機が得られる。 さらに、請求項３によれば、昇温部で予備加熱した満量の高温すすぎ用すすぎ 水を予備タンクに予め溜めておけるので、高温すすぎ処理時間をより一層短縮で き、総合処理時間の短い食器洗浄機が得られるという効果がある。 As is clear from the above description, according to the dishwasher of claim 1 of the present invention, the dishes are washed and rinsed by the washing water and the rinsing water which are heated in the temperature raising section to raise the temperature. Therefore, a high washing and rinsing effect can be obtained, the washing and rinsing time can be saved, and a dishwasher with a short total processing time can be obtained. Further, according to claim 2, since the washing water and the rinsing water are preheated by the heating means, not only a high washing and rinsing effect can be obtained from the beginning, but also a temperature which can obtain a desired washing effect can be obtained conventionally. Wash water etc. reaches faster than usual. Therefore, the washing and rinsing time of the dishes can be saved, and a dishwasher with a short total processing time can be obtained as described above. Furthermore, according to claim 3, since the full amount of high-temperature rinse water preheated in the temperature raising section can be stored in the spare tank in advance, the high-temperature rinse treatment time can be further shortened and the total treatment time can be shortened. There is an effect that a dishwasher can be obtained.
