Description

本発明は、食器等を洗浄する食器洗い機に関する。より詳しくは、本発明は、食器洗い機の洗剤投入時に、洗剤をヒータの近傍に投入する技術に関する。   The present invention relates to a dishwasher for washing dishes and the like. More specifically, the present invention relates to a technique for putting a detergent in the vicinity of a heater when the detergent is put into a dishwasher.

従来の食器洗い機は、運転コースなどを設定する入力装置と、前記入力装置の設定に基づいて洗浄、すすぎ、乾燥などの工程を逐次制御する制御装置とを備え、前記制御装置は、洗浄ポンプ、ヒータ、給水弁、送風ファン等の各種電装部品を制御して、洗浄、すすぎおよび乾燥の各工程を実行する。洗浄工程の実行に先立って、洗剤が洗剤投入部から投入されるが、従来の食器洗い機においては、洗剤が投入される洗浄槽の底部の位置は、ヒータから離れた位置に設定されている。また、洗浄工程は、所定の水位まで給水されると、ヒータへの通電とほぼ同時に洗浄ポンプを起動して開始される(例えば、特許文献1参照)。   A conventional dishwasher includes an input device that sets an operation course and the like, and a control device that sequentially controls processes such as washing, rinsing, and drying based on the setting of the input device, and the control device includes a washing pump, Various electric parts such as a heater, a water supply valve, and a blower fan are controlled to perform the cleaning, rinsing, and drying processes. Prior to the execution of the washing process, the detergent is introduced from the detergent introduction unit. In the conventional dishwasher, the position of the bottom of the washing tank into which the detergent is introduced is set at a position away from the heater. In addition, when the water is supplied to a predetermined water level, the cleaning process is started by starting the cleaning pump almost simultaneously with energization of the heater (see, for example, Patent Document 1).

従来の食器洗い機の構成について、以下に説明する。図8は、従来のビルトイン型の食器洗い機の側面断面図である。図8に示すように、使用者は、把手部18を持って本体1より洗浄槽3を引き出し、出現する開口部2から食器等の被洗浄物7を洗浄槽3内に収容する。また、使用者は、洗浄槽3内の前面近傍に配置された洗剤投入部14に定格量の洗剤を投入する。これにより、投入された洗剤は、洗浄槽3内底部の所定位置に毎回導かれる。   The configuration of a conventional dishwasher will be described below. FIG. 8 is a side sectional view of a conventional built-in dishwasher. As shown in FIG. 8, the user holds the handle portion 18, pulls out the cleaning tank 3 from the main body 1, and accommodates an object 7 to be cleaned such as tableware in the cleaning tank 3 from the opening 2 that appears. In addition, the user puts the rated amount of detergent into the detergent throwing portion 14 disposed in the vicinity of the front surface in the cleaning tank 3. Thereby, the introduced detergent is guided to a predetermined position at the bottom of the cleaning tank 3 every time.

使用者が洗浄槽3を元の位置に押し込み、開口部2が蓋11により閉塞されてから運転を開始すると、食器洗い機はモータにより駆動される洗浄ポンプ5を運転し、洗浄ポンプ5によって加圧された洗浄水を洗浄ノズル6から噴射し、被洗浄物7の洗浄及びすすぎ工程を行う。   When the user pushes the washing tub 3 into the original position and starts operation after the opening 2 is closed by the lid 11, the dishwasher operates the washing pump 5 driven by the motor and pressurizes by the washing pump 5. The cleaned water is sprayed from the cleaning nozzle 6 to perform the cleaning and rinsing process of the object 7 to be cleaned.

洗浄及びすすぎ工程で使用する被洗浄物7を洗浄するための洗浄水は、本体1の後部に取り付けられた給水弁15で供給され、洗浄槽3の底部の水溜部4に溜められる。   Washing water for washing the object 7 to be washed used in the washing and rinsing process is supplied by a water supply valve 15 attached to the rear part of the main body 1 and stored in a water reservoir 4 at the bottom of the washing tank 3.

補助水槽16は、洗浄槽3の底部の水溜部4に溜められた洗浄水を、残菜回収部10を介して洗浄水位検知装置20a及び溢水水位検知装置20bより成る水位検知装置20へと導いている。洗浄水位検知装置20aは、洗浄槽3内に基準となる量の水が溜められたことを検知する。溢水水位検知装置20bは、洗浄槽3内の水位が所定水位以上に高くなり、溢水の可能性があることを検知する。残菜回収部10は、洗浄槽3内底部の洗浄水の流れにおける下流側として、水溜部4内の最も低い位置に窪みとして設けられ、任意に着脱可能な残菜回収フィルター(図示せず)と目の粗い排水フィルター(図示せず)を有している。   The auxiliary water tank 16 guides the cleaning water stored in the water reservoir 4 at the bottom of the cleaning tank 3 to the water level detection device 20 including the cleaning water level detection device 20a and the overflow water level detection device 20b through the leftover vegetable recovery unit 10. ing. The cleaning water level detection device 20 a detects that a reference amount of water has been accumulated in the cleaning tank 3. The overflow water level detection device 20b detects that the water level in the cleaning tank 3 is higher than a predetermined water level and there is a possibility of overflow. The leftover collection part 10 is provided as a depression at the lowest position in the water reservoir 4 on the downstream side in the flow of the washing water in the bottom of the washing tank 3, and an arbitrarily removable leftover collection filter (not shown). And a rough drainage filter (not shown).

また、制御装置21が本体1に備えられている。制御装置21は、洗浄ポンプ5、ヒータ8、給水弁15、送風ファン17等の各種電装部品を制御して、洗浄、すすぎおよび乾燥の各工程を実行する。   A control device 21 is provided in the main body 1. The control device 21 controls various electrical components such as the cleaning pump 5, the heater 8, the water supply valve 15, and the blower fan 17, and executes cleaning, rinsing, and drying processes.

使用者が入力装置19により運転コースを設定すると、制御装置21は入力装置19の設定に基づいて食器洗い機の運転を開始する。入力装置19で標準のコースを設定した場合、洗浄槽3への給水が、一定の水量(水位)までは洗浄水位検知装置20aの検知情報によって正確に行われる(基準水位)。そして、しばらく洗浄ポンプ5を動作させ、次いで給水弁15への通電を所定時間行い追加する補給水を加えて、洗浄槽3内の洗浄水の水
量は洗浄に必要かつ十分な水量に調整される。
When the user sets an operation course with the input device 19, the control device 21 starts operation of the dishwasher based on the setting of the input device 19. When the standard course is set by the input device 19, the water supply to the cleaning tank 3 is accurately performed based on the detection information of the cleaning water level detection device 20a up to a certain amount of water (water level) (reference water level). Then, the cleaning pump 5 is operated for a while, and then the supply water 15 is energized for a predetermined time to add supplementary water to be added, so that the amount of cleaning water in the cleaning tank 3 is adjusted to a necessary and sufficient amount for cleaning. .

給水が完了すると、ヒータ8に通電すると同時に洗浄ポンプ5を運転し、洗浄槽3内底部の所定の位置に事前に投入された洗剤を効率よく溶かしながら、洗浄水を洗浄ノズル6から噴射して被洗浄物7を洗浄する。   When the water supply is completed, the heater 8 is energized and at the same time the cleaning pump 5 is operated, and the cleaning water is sprayed from the cleaning nozzle 6 while efficiently dissolving the detergent previously introduced into a predetermined position in the bottom of the cleaning tank 3. The object 7 to be cleaned is cleaned.

特開2006−61450号公報JP 2006-61450 A

投入された洗剤の溶解速度は、洗浄水の温度上昇と共に、また、洗浄槽3内を循環する洗浄水の流れによって促進される。上記従来の構成においては、洗剤が投入される洗浄槽3の底部の位置は、ヒータ8から離れた位置に設定されており、かつ、洗浄工程の開始時に、ヒータ8への通電とほぼ同時に洗浄ポンプ5を起動している。そのため、給水水温が低い場合等での運転初期の洗浄水の洗剤濃度は、洗剤が完全に溶解した時と比較して低く、また、水温が高まる運転の後半部では、一定時間給水される補給水や汚染成分との反応で洗剤成分濃度は著しく希薄化して効果を失ってきているため、最大限の洗浄効果を得ることができない。   The dissolution rate of the introduced detergent is promoted by the flow of the cleaning water circulating in the cleaning tank 3 as the temperature of the cleaning water rises. In the above conventional configuration, the position of the bottom of the cleaning tank 3 into which the detergent is introduced is set at a position away from the heater 8, and cleaning is performed almost simultaneously with energization of the heater 8 at the start of the cleaning process. The pump 5 is activated. Therefore, the detergent concentration in the initial stage of operation when the feed water temperature is low is lower than that when the detergent is completely dissolved. Since the detergent component concentration has become extremely dilute due to reaction with water and contaminating components and has lost its effect, the maximum cleaning effect cannot be obtained.

本発明は、上記従来の課題を解決するもので、投入される洗剤をヒータの近傍に集中的に導き、洗剤の溶解速度をより一層高めることで、洗浄運転開始時の洗浄力をより高めることができる食器洗い機を提供するものである。   The present invention solves the above-described conventional problems, and concentrates the detergent to be introduced in the vicinity of the heater and further increases the detergent dissolution rate, thereby further increasing the cleaning power at the start of the cleaning operation. The dishwasher which can do is provided.

前記従来の課題を解決するために、本発明は、被洗浄物を収容し、内底部に洗浄水を溜める水溜部を有する洗浄槽と、前記洗浄槽内に設けられ洗浄水を被洗浄物に噴射する洗浄ノズルと、前記洗浄ノズルに洗浄水を供給して前記洗浄槽内で洗浄水を循環させる洗浄ポンプと、前記水溜部に設けられ洗浄水を加熱するヒータと、前記洗浄槽内底部の洗浄水の流れにおける下流側として、前記水溜部内の最も低い位置に設けられた残菜回収部と、前記洗浄槽内に設けられ、投入された洗剤を前記洗浄槽内底部の一定位置に導く洗剤投入部と、前記洗浄槽に連通させて設けられ、洗浄水位を検知する水位検知装置と、前記洗浄槽内に給水する給水弁と、前記ヒータ、前記洗浄ポンプ、前記給水弁等の各種電装部品を制御して洗浄、すすぎ、乾燥の各工程を実行する制御装置とを備え、前記制御装置が前記給水弁を開いて給水を開始する前に、使用者が洗剤を前記洗剤投入部に投入することで、前記ヒータ近傍に洗剤が導かれ配置されるように構成された食器洗い機である。   In order to solve the above-described conventional problems, the present invention provides a cleaning tank having a water reservoir for storing an object to be cleaned and storing cleaning water in an inner bottom, and the cleaning water provided in the cleaning tank to the object to be cleaned. A cleaning nozzle for spraying, a cleaning pump for supplying cleaning water to the cleaning nozzle and circulating the cleaning water in the cleaning tank, a heater provided in the water reservoir for heating the cleaning water, and a bottom of the cleaning tank As a downstream side in the flow of washing water, a leftover collection part provided in the lowest position in the water reservoir, and a detergent provided in the washing tank and guiding the introduced detergent to a fixed position in the bottom of the washing tank Various electrical components such as a charging unit, a water level detection device that is provided in communication with the cleaning tank and detects the cleaning water level, a water supply valve that supplies water into the cleaning tank, the heater, the cleaning pump, and the water supply valve Controlling each of washing, rinsing and drying A control device that performs the process, and before the control device opens the water supply valve and starts water supply, the user introduces the detergent into the detergent introduction section, so that the detergent is introduced to the vicinity of the heater. A dishwasher configured to be arranged.

これにより、ヒータ近傍の熱や水温上昇にともなって洗剤の溶解速度が高まり、結果として高濃度かつ高温の洗浄水が容易に得られるため、洗剤量を増すことなく、従来よりも洗浄運転開始時により高い洗浄力を有する食器洗い機を実現可能とする。   As a result, the dissolution rate of the detergent increases as the heat in the vicinity of the heater and the water temperature rise, and as a result, high-concentration and high-temperature washing water can be easily obtained. Makes it possible to realize a dishwasher having a high cleaning power.

本発明の食器洗い機によれば、高濃度かつ高温の洗浄水が比較的短時間で容易に得られるとともに、洗浄運転のより早い段階での洗浄力の向上により、洗剤量を増すことなく、従来よりも高い洗浄力を有する食器洗い機を提供することができる。   According to the dishwasher of the present invention, high-concentration and high-temperature washing water can be easily obtained in a relatively short time, and the improvement in washing power at an earlier stage of washing operation makes it possible to increase the amount of detergent without increasing the amount of detergent. A dishwasher having higher cleaning power can be provided.

第1の発明は、被洗浄物を収容し、内底部に洗浄水を溜める水溜部を有する洗浄槽と、前記洗浄槽内に設けられ洗浄水を被洗浄物に噴射する洗浄ノズルと、前記洗浄ノズルに洗浄水を供給して前記洗浄槽内で洗浄水を循環させる洗浄ポンプと、前記水溜部に設けられ洗浄水を加熱するヒータと、前記洗浄槽内底部の洗浄水の流れにおける下流側として、前記水溜部内の最も低い位置に設けられた残菜回収部と、前記洗浄槽内に設けられ、投入された洗剤を前記洗浄槽内底部の一定位置に導く洗剤投入部と、前記洗浄槽に連通させて設けられ、洗浄水位を検知する水位検知装置と、前記洗浄槽内に給水する給水弁と、前記ヒータ、前記洗浄ポンプ、前記給水弁等の各種電装部品を制御して洗浄、すすぎ、乾燥の各工程を実行する制御装置とを備え、前記制御装置が前記給水弁を開いて給水を開始する前に、使用者が洗剤を前記洗剤投入部に投入することで、前記ヒータ近傍に洗剤が導かれ配置される食器洗い機である。   According to a first aspect of the present invention, there is provided a cleaning tank having a water reservoir for storing an object to be cleaned and collecting cleaning water at an inner bottom thereof, a cleaning nozzle provided in the cleaning tank for injecting the cleaning water onto the object to be cleaned, and the cleaning As a downstream side in the flow of cleaning water at the bottom of the cleaning tank, a cleaning pump for supplying cleaning water to the nozzle and circulating the cleaning water in the cleaning tank, a heater provided in the water reservoir, and heating the cleaning water A leftover collection part provided at the lowest position in the water reservoir, a detergent input part provided in the washing tank, for guiding the introduced detergent to a fixed position at the bottom of the washing tank, and the washing tank. A water level detection device that is provided in communication and detects a cleaning water level, a water supply valve that supplies water into the cleaning tank, and controls and controls various electrical components such as the heater, the cleaning pump, and the water supply valve. Equipped with a control device that performs each process of drying Before the controller starts the water supply by opening the water supply valve, when the user turns on the detergent into the detergent supply part is a dishwasher detergent is placed guided to the vicinity of the heater.

これにより、洗浄水の水温上昇やヒータの熱を受けて、ヒータ近傍に投下された洗剤の溶解速度を飛躍的に向上させることができるため、従来よりも効率的で、洗浄運転開始当初より高い洗浄力を有する食器洗い機を実現することができる。また、洗剤をヒータの近傍に投入することで、熱によって洗剤の溶解速度が飛躍的に向上するため、洗剤が定格量に対して多めに投入された場合でも、洗剤の溶け残りを発生させることがない。   As a result, it is possible to drastically improve the dissolution rate of the detergent dropped in the vicinity of the heater in response to a rise in the temperature of the washing water and the heat of the heater, which is more efficient than before and higher than the beginning of the washing operation. A dishwasher having detergency can be realized. In addition, by putting detergent in the vicinity of the heater, the dissolution rate of the detergent is greatly improved by heat, so even if detergent is thrown in a larger amount than the rated amount, it will cause undissolved detergent to be generated. There is no.

第2の発明は、上記第1の発明において、前記洗剤投入部は、洗剤を前記洗浄槽内底部の洗浄水の流れにおける上流側の位置に導くように設けられたことで、ヒータの近傍で生成された洗浄液を、洗浄ポンプの動作と共に、高温のヒータ周囲を通過させながら引き込み循環させることができるため、従来よりも効率的で、洗浄運転開始当初から、より高い洗浄力を有する食器洗い機を実現することができる。   According to a second aspect of the present invention, in the first aspect, the detergent charging portion is provided to guide the detergent to a position on the upstream side in the flow of the cleaning water at the bottom of the cleaning tank.

Since the cleaning liquid of high concentration and high temperature generated in the vicinity can be drawn into the cleaning pump at once by operating the cleaning pump, the detergent is dissolved better before the cleaning water is jetted from the cleaning nozzle. A dishwasher having a higher cleaning power can be realized from the beginning of the cleaning operation while obtaining a high concentration and high temperature cleaning liquid.

第4の発明は、上記第1〜第3のうちいずれか一つの発明において、洗剤が導かれる洗剤受け部を有し、前記洗剤受け部は、前記ヒータよりも高い位置で、かつ給水される水位よりも低い位置に設けられたことで、ヒータにより加熱された洗浄水が対流現象により上昇し、洗剤受け部に投入された洗剤が水温が高い洗浄水に晒されることにより、短時間で高温かつ高濃度の洗剤液を得ることができるため、本洗浄開始当初から高濃度かつ高温の洗剤液を洗浄に利用できる食器洗い機を実現することができる。   4th invention has a detergent receiving part in which detergent is guide | induced in any one invention among the said 1st-3rd, The said detergent receiving part is a position higher than the said heater, and is supplied with water. By providing it at a position lower than the water level, the cleaning water heated by the heater rises due to the convection phenomenon, and the detergent put in the detergent receiving part is exposed to the cleaning water having a high water temperature, so that the temperature becomes high in a short time. And since a high concentration detergent liquid can be obtained, the dishwasher which can utilize a high concentration and high temperature detergent liquid for washing | cleaning from the beginning of this washing | cleaning is realizable.

第5の発明は、上記第1〜第4のうちいずれか一つの発明において、前記制御装置は、前記水位検知装置が検知する、洗浄工程時より低い水位状態で給水を止め、前記ヒータに通電して前記洗浄槽内底部の洗浄水を加熱し、所定温度に達するまでの間、前記洗浄ポン
プの動作を行わないように制御することで、ヒータ近傍に投入した洗剤成分をより一層洗浄水に溶解させ、洗剤濃度の高い高温の洗浄液を作ることができるため、洗剤の量を増すことなく、洗浄運転開始当初に従来よりも高い洗浄力を有する食器洗い機を実現することができる。
According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the control device stops supplying water at a lower water level than that detected during the cleaning process and is energized to the heater. Then, the cleaning water in the bottom of the cleaning tank is heated and controlled so as not to operate the cleaning pump until the temperature reaches a predetermined temperature. Since a high-temperature washing liquid having a high concentration of detergent can be dissolved, a dishwasher having a higher washing power than before can be realized at the beginning of the washing operation without increasing the amount of detergent.

また、補助水槽16内に設けられた水位検知装置20が、残菜回収部10(排水口)の下部と配管によって連通されて設けられている。水位検知装置20は、洗浄水位検知装置20aと溢水水位検知装置20bとを有し、洗浄水位検知装置20aにより洗浄槽3内に基準となる量の洗浄水が溜められたことを所定の検知水位(基準水位)として水位で検知する。洗浄槽3内の洗浄水の温度は、洗浄槽3の底部外側に固着された温度検知装置(図
示せず)によって検知される。
Moreover, the water level detection apparatus 20 provided in the auxiliary water tank 16 is provided in communication with the lower part of the leftovers collection part 10 (drain outlet) by piping. The water level detection device 20 includes a cleaning water level detection device 20a and an overflow water level detection device 20b, and a predetermined detection water level indicates that a reference amount of cleaning water is accumulated in the cleaning tank 3 by the cleaning water level detection device 20a. It is detected at the water level as the (reference water level). The temperature of the cleaning water in the cleaning tank 3 is detected by a temperature detector (not shown) fixed to the outside of the bottom of the cleaning tank 3.

また、洗浄ポンプ5、ヒータ8、給水弁15、送風ファン17等の各種電装部品を制御して食器洗い機を運転する制御装置21が、本体1に備えられている。制御装置21は、入力装置19から入力される電源入切、コース選択、運転スタート等の入力情報と、水位検知装置20や温度検知装置等からの検知情報と、制御プログラムからの指令に基づいて各種電装部品を制御し、洗浄、すすぎ、乾燥の各工程を実行する。   Further, the main body 1 is provided with a control device 21 that controls various electrical components such as the washing pump 5, the heater 8, the water supply valve 15, and the blower fan 17 to operate the dishwasher. The control device 21 is based on input information input from the input device 19 such as power on / off, course selection, operation start, detection information from the water level detection device 20 or temperature detection device, and a command from the control program. Various electrical components are controlled, and cleaning, rinsing and drying processes are executed.

次に、以上のように構成された食器洗い機について、その動作および作用を説明する。食器洗い機の基本動作および作用は、従来例として示した食器洗い機と同様であるので、説明を省略する。   Next, the operation and action of the dishwasher configured as described above will be described. Since the basic operation and action of the dishwasher are the same as those of the dishwasher shown as the conventional example, the description thereof is omitted.

制御装置21は、洗浄運転を開始すると、最初に洗浄ポンプ5を起動して排水を行い(この時、洗浄ポンプ5は排水ポンプとして動作する)、その後、給水弁15を動作させて水無し状態から洗浄水位検知装置20aが動作するまで洗浄槽3内に給水を行う。洗浄水位検知装置20aが基準となる検知水位を検知すると、この検知情報に基づいて制御装置21が給水(メイン給水)を完了する。この時の洗浄槽3内の洗浄水の基準となる検知水位は、その後に実行される洗浄時の水位より低く設定されている。   When the controller 21 starts the cleaning operation, the controller 21 first activates the cleaning pump 5 to perform drainage (at this time, the cleaning pump 5 operates as a drainage pump), and then operates the water supply valve 15 so that there is no water. Until the cleaning water level detection device 20a operates, water is supplied into the cleaning tank 3. When the cleaning water level detection device 20a detects the reference detection water level, the control device 21 completes the water supply (main water supply) based on the detection information. The detected water level that serves as a reference for the cleaning water in the cleaning tank 3 at this time is set lower than the water level at the time of subsequent cleaning.

本実施の形態1の食器洗い機において、制御装置21は、この洗浄時の水位よりも低い水位状態でヒータ8を所定の時間動作させる。この時、洗浄ポンプ5は動作させない。これによって、洗浄槽3内に蓄えられた洗浄水の温度が上昇する。この洗浄水の温度上昇に伴って、洗剤投入部14によりヒータ8上で洗浄水の流れより上流側に導かれていた洗剤の溶解が促進される。なお、所定時間内で洗浄水温が規定値に達していない場合には、ヒータ8は洗浄水温度が規定値になるまで通電される。特に、食器洗い機で使用される洗剤中に含まれる成分酵素の最大活性温度(至適温度)はおよそ40℃〜60℃であり、酵素で分解される食器汚れに対してはこの温度を維持すると効果的に洗浄することが可能である。   In the dishwasher of the first embodiment, the control device 21 operates the heater 8 for a predetermined time in a water level state lower than the water level at the time of washing. At this time, the cleaning pump 5 is not operated. As a result, the temperature of the cleaning water stored in the cleaning tank 3 rises. As the temperature of the cleaning water rises, dissolution of the detergent introduced upstream of the flow of cleaning water on the heater 8 by the detergent charging unit 14 is promoted. If the cleaning water temperature does not reach the specified value within the predetermined time, the heater 8 is energized until the cleaning water temperature reaches the specified value. In particular, the maximum activity temperature (optimum temperature) of the component enzyme contained in the detergent used in the dishwasher is approximately 40 ° C. to 60 ° C., and this temperature is maintained for dish stains decomposed by the enzyme. It is possible to clean effectively.

制御装置21は、洗浄水の加熱が完了すると洗浄ポンプ5を間欠運転で動作させて、予備洗浄を行う。これによって、被洗浄物7などに洗剤が高濃度かつ高温の洗浄水が噴射される。この時、洗浄ポンプ5の動作は必ずしも間欠である必要はなく、連続運転でもかまわない。   When the heating of the cleaning water is completed, the control device 21 operates the cleaning pump 5 in an intermittent operation to perform preliminary cleaning. As a result, high-concentration and high-temperature cleaning water is sprayed on the object 7 to be cleaned. At this time, the operation of the cleaning pump 5 does not necessarily need to be intermittent, and may be continuously operated.

その後に行われる洗浄時の洗浄槽3内の水量は、被洗浄物7に付着した食品汚染や洗剤成分による泡立ち等を考慮し、一連の運転を通してエアガミ音や性能面への影響が生じないようにする必要がある。本実施の形態1の食器洗い機においても、制御装置21は、洗浄ポンプ5を所定時間動作させた後で、従来と同じく所定時間の給水弁15への通電を行い、追加の補給水を加えて、洗浄中の洗浄槽3内の水量を洗浄に必要かつ十分な水量に調整する。   The amount of water in the cleaning tank 3 at the time of subsequent cleaning is determined so that air pollution and performance are not affected through a series of operations in consideration of food contamination adhering to the object 7 to be cleaned and foaming due to detergent components. It is necessary to. Also in the dishwasher according to the first embodiment, the control device 21 energizes the water supply valve 15 for a predetermined time as in the prior art after operating the cleaning pump 5 for a predetermined time, and adds additional makeup water. The amount of water in the washing tank 3 being washed is adjusted to a necessary and sufficient amount of water for washing.

以上のように、本実施の形態1の食器洗い機は、洗浄工程において洗浄槽3内に給水された洗浄水の温度が低くても、洗浄ポンプ5を動作させることなく、まず洗浄水をヒータ8で加熱し、投入された洗剤を洗浄水に対して十分に溶解させることができるため、洗浄運転開始の噴射当初から、高濃度かつ高温の洗浄水で洗浄を行うことが可能となる。特に、投入された洗剤を、補給水を追加する前の洗浄槽3内の少ない水に対して十分に溶解させるようにすれば、洗浄運転開始の噴射当初から、より高濃度かつ高温の洗浄水で洗浄を行うことが可能となる。   As described above, the dishwasher according to the first embodiment uses the washing water to the heater 8 without operating the washing pump 5 even when the temperature of the washing water supplied into the washing tank 3 is low in the washing process. It is possible to sufficiently wash the detergent supplied in the washing water with the high-concentration and high-temperature washing water from the beginning of the washing operation. In particular, if the introduced detergent is sufficiently dissolved in the small amount of water in the washing tank 3 before adding makeup water, the washing water having a higher concentration and higher temperature from the beginning of the washing operation start. It becomes possible to perform washing with.

また、本実施の形態1の食器洗い機においては、洗浄槽3内底部の洗浄水の流れにおけ
る上流寄りのヒータ8上に洗剤を配置するため、洗浄ポンプ5の動作と共に洗浄水が高温状態のヒータ8近傍を一旦通過し、さらに洗剤の溶解が促進され、投入された洗剤を前記補給水を追加する前の少ない水に対して十分に溶解させることができるため、洗浄運転開始の噴射当初から、より高濃度かつ高温の洗浄水で洗浄を行うことが可能となる。
Further, in the dishwasher of the first embodiment, since the detergent is disposed on the upstream heater 8 in the flow of the cleaning water at the bottom of the cleaning tank 3, the heater in which the cleaning water is in a high temperature state with the operation of the cleaning pump 5. Since the dissolution of the detergent is further promoted and the introduced detergent can be sufficiently dissolved in a small amount of water before adding the make-up water from the beginning of the washing operation, It becomes possible to perform washing with higher-concentration and high-temperature washing water.

また、洗剤をヒータ8の近傍に投入することで、熱によって洗剤の溶解速度が飛躍的に向上するため、洗剤が定格量に対して多めに投入された場合でも、洗剤の溶け残りを発生させることがない。   Further, since the detergent is drastically improved by heating by putting the detergent in the vicinity of the heater 8, even if the detergent is thrown in a larger amount than the rated amount, the detergent remains undissolved. There is nothing.

以上のように本発明の食器洗い機においては、洗浄槽3内の水温が低くても、洗浄ポンプ5を動作させることなく、投入された洗剤を十分に溶解させることができるため、洗浄運転開始の噴射当初から、より高濃度かつ高温の洗浄水で洗浄を行うことが可能となる。したがって、本発明の食器洗い機の構成によれば、洗浄ポンプ5を動作させる前に高濃度・高温の洗浄水を得ることが可能になり、汚染と混じる前の純粋な高濃度かつ高温の洗浄水を所定時間食器等の被洗浄物に噴射させることで、同じ洗剤量で(または同じ水量でも)、従来よりも高い洗浄効果を得ることができる食器洗い機を提供することができる。   As described above, in the dishwasher of the present invention, even if the water temperature in the washing tub 3 is low, the washing detergent 5 can be sufficiently dissolved without operating the washing pump 5. From the beginning of injection, it becomes possible to perform cleaning with higher-concentration and higher-temperature cleaning water. Therefore, according to the configuration of the dishwasher of the present invention, it becomes possible to obtain high concentration and high temperature washing water before operating the washing pump 5, and pure high concentration and high temperature washing water before mixing with contamination. Can be provided on the object to be cleaned such as tableware for a predetermined period of time, thereby providing a dishwasher capable of obtaining a higher cleaning effect than before with the same amount of detergent (or even with the same amount of water).

(実施の形態2)
図3は、本発明の実施の形態2における食器洗い機の側面断面図である。本実施の形態2の食器洗い機の上記実施の形態1と異なる点は、はしやスプーン等の小物関係を入れる食器かご13cに一体化して設けられた洗剤投入部14は、投入された洗剤が洗浄槽3内底部の洗浄水の流れにおける下流側の位置にくるように、すなわちヒータ8と残菜回収部10との間に落下するように配置され、投入された洗剤は、洗剤投入部14を介してヒータ8上の下流寄りに導かれるように構成した点である。その他の構成は、実施の形態1と同様である。
(Embodiment 2)
FIG. 3 is a side sectional view of the dishwasher according to Embodiment 2 of the present invention. The difference from the first embodiment of the dishwasher according to the second embodiment is that the detergent input section 14 provided integrally with the tableware basket 13c for inserting small items such as ladders and spoons, The detergent placed in the bottom of the washing tank 3 is positioned downstream of the flow of washing water, that is, so as to fall between the heater 8 and the leftover collection part 10. It is the point which comprised so that it might be guide | induced to the downstream vicinity on the heater 8 via. Other configurations are the same as those in the first embodiment.

本実施の形態2の食器洗い機においては、洗浄槽3内に給水された水の温度が低くても、洗浄ポンプ5を動作させることなく、投入された洗剤を、補給水を追加する前の洗浄槽3内の少ない水に対して十分に溶解させることができるため、噴射当初より高濃度かつ高温の洗浄水で洗浄を行うことが可能となる。   In the dishwasher according to the second embodiment, even if the temperature of the water supplied into the washing tub 3 is low, the washing detergent 5 is washed before adding makeup water without operating the washing pump 5. Since it can be sufficiently dissolved in a small amount of water in the tank 3, it is possible to perform washing with washing water having a high concentration and high temperature from the beginning of injection.

また、本実施の形態2の食器洗い機においては、洗浄槽3内底部の洗浄水の流れにおける下流寄り(残菜回収部10側)のヒータ8近傍に洗剤を配置するため、その一帯で生成した高温で高濃度の洗浄水を、洗浄ポンプ5の動作と共に一気に引き込むことができるため、洗浄ノズル6より洗浄水が噴射される当初より、一層高い洗浄力で洗浄を行うことが可能となる。   Further, in the dishwasher according to the second embodiment, the detergent is disposed in the vicinity of the heater 8 near the downstream (residue collection unit 10 side) in the flow of the washing water in the bottom of the washing tub 3, so that the detergent is generated in one area. Since high-temperature and high-concentration cleaning water can be drawn at once with the operation of the cleaning pump 5, it is possible to perform cleaning with a higher cleaning power than when the cleaning water is jetted from the cleaning nozzle 6.

なお、上記実施の形態2と前記実施の形態1とを併用すれば、洗浄水の流れにおける上流側と下流側との双方において高温で高濃度の洗浄水を生成することができ、さらなる洗浄力の向上を図ることができる。   In addition, if the said Embodiment 2 and the said Embodiment 1 are used together, high concentration washing water can be produced | generated at high temperature in both the upstream and downstream in the flow of washing water, and further washing power Can be improved.

A heater 37 provided for heating the cleaning water and a temperature detection means 38 such as a thermistor provided outside the cleaning tank 31 for detecting the temperature of the cleaning water are provided. The periphery of the heater 37 is protected by a heater protection component 39 and a fan case 40 having a ventilation path.

また、水溜部31aが洗浄槽31の内底部に設けられている。被洗浄物46から洗い落とされた残菜を回収する残菜回収フィルター有する残菜回収部41(排水口)が水溜部31aに設けられている。給水弁42が本体30の後部に設けられている。給水弁42が作動することによって配管を通じて洗浄槽31内に水道水が供給される。補助水槽43が残菜回収部41の下部と配管によって連通されて設けられており、補助水槽43に設けられた水位検知装置44が、洗浄槽31内に基準となる量の水が溜められたことを所定の検知水位(基準水位)として水位で検知する。   A water reservoir 31 a is provided on the inner bottom of the cleaning tank 31. The water reservoir 31a is provided with a leftover collection part 41 (drain port) having a leftover collection filter for collecting leftovers washed away from the object to be cleaned 46. A water supply valve 42 is provided at the rear of the main body 30. When the water supply valve 42 is operated, tap water is supplied into the cleaning tank 31 through the pipe. The auxiliary water tank 43 is provided in communication with the lower part of the leftover vegetable collection unit 41 by a pipe, and the water level detection device 44 provided in the auxiliary water tank 43 stores a reference amount of water in the cleaning tank 31. This is detected at the water level as a predetermined detection water level (reference water level).

また、扉34の下方に制御装置45を備えている。この制御装置45は、制御シーケンスを記憶させたプログラムに従って、温度検知手段38の検知情報及び使用者によって入力される入力手段(図示せず)からの入力情報に基づき、洗浄ノズル35、洗浄ポンプ36、ヒータ37等を制御して、洗浄、すすぎ、加熱すすぎ、乾燥の各工程を実行する。   A control device 45 is provided below the door 34. This control device 45 is based on the detection information of the temperature detection means 38 and the input information (not shown) input from the input means (not shown) input by the user according to the program storing the control sequence. Then, the heater 37 and the like are controlled to execute the cleaning, rinsing, heating rinsing and drying processes.

図5〜図7において、ファンケース40は洗剤受け部47を有しており、洗剤受け部47は、食器かご32に設けられた洗剤投入部48を介して投入された洗剤Sを受ける構成となっている。洗剤受け部47は、ヒータ37より上方の高い位置で、かつ所定の検知水位(基準水位)より低い位置に設けられている。洗剤受け部47は略L字形状を成し、洗剤投入部48の下方で洗剤Sを受ける保持部47aの周囲には立設部47bを有して洗剤Sがこぼれないように保持し、洗剤投入部48の下方から外れたヒータ37の上方の流水部47cでは、立設部47bを有さず、洗浄水がスムーズに出入りして洗剤Sを溶解し、その洗剤液が容易に流出することができるようになっている。また、洗浄水及び洗剤液の出入りは、洗剤受け部47で流水部47cより低い位置に設けられた通水部47dでも行われる。   5 to 7, the fan case 40 has a detergent receiving part 47, and the detergent receiving part 47 receives the detergent S introduced through the detergent introducing part 48 provided in the tableware basket 32. It has become. The detergent receiver 47 is provided at a high position above the heater 37 and at a position lower than a predetermined detected water level (reference water level). The detergent receiving portion 47 is substantially L-shaped, and has a standing portion 47b around the holding portion 47a that receives the detergent S below the detergent charging portion 48 to hold the detergent S so that it does not spill. In the flowing water part 47c above the heater 37 which is removed from the lower part of the charging part 48, there is no standing part 47b, the washing water smoothly enters and exits to dissolve the detergent S, and the detergent liquid easily flows out. Can be done. In addition, the cleaning water and the detergent liquid are also moved in and out of the water passage portion 47 d provided at a position lower than the flowing water portion 47 c in the detergent receiver 47.

本実施の形態2において、洗剤受け部47は保持部47aと流水部47cの全体がヒータ37より上方に構成されている。なお、洗剤受け部47の全体がヒータ37より上方に構成されていることに限定されるものではなく、少なくとも流水部47cがヒータより上方に構成されていれば良く、保持部47aはなるべく多くの部分がヒータ37より上方に構成されることが望ましい。また、洗浄水の出入りができるだけスムーズに行われる構成が望ましく、例えば、流水部47cと通水部47dのように複数の出入り部分を設け、特にこれらの高さを変えると対流現象を有効に利用することができて好ましい。また、立設部47bは垂直である必要はなく、要は投入された洗剤Sがこぼれにくいように保持部47aが形成されていれば良く、立設部47bの上端は所定の検知水位より高い位置に設けられていても構わない。   In the second embodiment, the detergent receiving portion 47 is configured such that the holding portion 47 a and the flowing water portion 47 c are entirely above the heater 37. The entire detergent receiving portion 47 is not limited to be configured above the heater 37, and at least the flowing water portion 47c may be configured above the heater, and the holding portion 47a may be as many as possible. It is desirable that the portion is formed above the heater 37. In addition, it is desirable that the cleaning water flow in and out as smoothly as possible. For example, a plurality of inflow and outflow portions such as a flowing water portion 47c and a water flow portion 47d are provided, and the convection phenomenon is effectively used by changing the height of these portions This is preferable. Further, the standing portion 47b does not need to be vertical. In short, it is only necessary that the holding portion 47a is formed so that the introduced detergent S is not easily spilled, and the upper end of the standing portion 47b is higher than a predetermined detected water level. It may be provided at the position.

以上のように構成された食器洗い機について、その動作および作用を説明する。制御装置45は、洗浄運転を開始すると、最初に洗浄ポンプ36を起動して排水を行い(この時、洗浄ポンプ36は排水ポンプとして動作する)、その後、給水弁42を動作させて水無し状態から水位検知装置44が動作するまで洗浄槽31内に給水を行う。水位検知装置44が基準となる検知水位を検知すると、この検知情報に基づいて制御装置45が給水(メイン給水)を完了する。この時の洗浄槽31内の洗浄水の基準となる検知水位は、後に実
行される本洗浄時の水位より低く設定されている。
About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated. When starting the cleaning operation, the control device 45 first activates the cleaning pump 36 to perform drainage (at this time, the cleaning pump 36 operates as a drainage pump), and then operates the water supply valve 42 so that there is no water. Until the water level detection device 44 operates, water is supplied into the cleaning tank 31. When the water level detection device 44 detects the reference detection water level, the control device 45 completes the water supply (main water supply) based on the detection information. The detected water level serving as a reference for the cleaning water in the cleaning tank 31 at this time is set lower than the water level at the time of the main cleaning that will be executed later.

本実施の形態3の食器洗い機において、制御装置45は、本洗浄時の水位よりも一層低いこの水位状態で、ヒータ37を所定の時間動作させる。この時、洗浄ポンプ36は動作させない。これによって、洗浄槽31内に蓄えられた洗浄水の温度が上昇する。また、予め運転前に洗剤は洗剤受け部47にセットされているが、図7に示すように洗剤受け部47は、ヒータ37より上方の高い位置で、かつ洗浄水位より低い位置に設けられているため、ヒータ37により加熱された洗浄水が対流現象で上昇し、洗剤受け部47に投入された洗剤が水温が高い洗浄水に晒される。この洗浄水の温度上昇に伴って、ヒータ37上で洗浄水の流れより上流側に導かれていた洗剤の溶解が促進され、短時間で高温かつ高濃度の洗剤液を得ることができる。なお、所定時間内で洗浄水温が規定値に達していない場合には、ヒータ37は洗浄水温度が規定値になるまで通電される。   In the dishwasher of the third embodiment, the control device 45 operates the heater 37 for a predetermined time in this water level state that is lower than the water level at the time of main washing. At this time, the cleaning pump 36 is not operated. As a result, the temperature of the cleaning water stored in the cleaning tank 31 rises. Before the operation, the detergent is set in the detergent receiving portion 47 in advance, but as shown in FIG. 7, the detergent receiving portion 47 is provided at a high position above the heater 37 and at a position lower than the washing water level. Therefore, the washing water heated by the heater 37 rises by a convection phenomenon, and the detergent thrown into the detergent receiving part 47 is exposed to the washing water having a high water temperature. As the temperature of the cleaning water rises, dissolution of the detergent guided upstream from the flow of cleaning water on the heater 37 is promoted, and a high-temperature and high-concentration detergent liquid can be obtained in a short time. If the cleaning water temperature does not reach the specified value within a predetermined time, the heater 37 is energized until the cleaning water temperature reaches the specified value.

制御装置45は、洗浄水の加熱が完了すると洗浄ポンプ36を間欠運転で動作させて、予備洗浄を行う。これによって、被洗浄物46などに洗剤が高濃度かつ高温の洗浄水が噴射される。なお、洗浄ポンプ36の動作は必ずしも間欠である必要はなく、連続運転でもかまわない。   When the heating of the cleaning water is completed, the control device 45 operates the cleaning pump 36 in an intermittent operation to perform preliminary cleaning. As a result, high-concentration and high-temperature cleaning water is sprayed onto the object to be cleaned 46 and the like. Note that the operation of the cleaning pump 36 is not necessarily intermittent, and may be continuously operated.

その後に行われる本洗浄時の洗浄槽31内の水量は、被洗浄物46に付着した食品汚染や洗剤成分による泡立ち等を考慮し、一連の運転を通してエアガミ音や性能面への影響が生じないようにする必要がある。本実施の形態3の食器洗い機においても、制御装置45は、洗浄ポンプ36を所定時間動作させた後で、従来と同じく所定時間の給水弁15への通電を行い、追加の補給水を加えて、洗浄中の洗浄槽31内の水量を本洗浄に必要かつ十分な水量に調整する。   The amount of water in the cleaning tank 31 at the time of the main cleaning performed thereafter takes into account food contamination attached to the object to be cleaned 46, foaming due to detergent components, and the like, and there is no influence on air noise or performance through a series of operations. It is necessary to do so. Also in the dishwasher of the third embodiment, the control device 45 operates the washing pump 36 for a predetermined period of time, then energizes the water supply valve 15 for a predetermined period of time as before, and adds additional makeup water. The amount of water in the cleaning tank 31 being cleaned is adjusted to the amount necessary and sufficient for the main cleaning.

以上のように、本実施の形態3の食器洗い機は、洗浄工程において洗浄槽31内に給水された洗浄水の水温が低くても、洗浄ポンプ36を動作させることなく、まず洗浄水をヒータ37で加熱し、投入された洗剤を洗浄水に対して十分に溶解させることができるため、洗浄運転開始の噴射当初から、高濃度かつ高温の洗浄水で洗浄を行うことが可能となる。特に、投入された洗剤を、補給水を追加する前の洗浄槽31内の少ない水に対して十分に溶解させるようにすれば、洗浄運転開始の噴射当初から、より高濃度かつ高温の洗浄水で洗浄を行うことが可能となる。   As described above, the dishwasher according to the third embodiment is configured so that the washing water is first supplied to the heater 37 without operating the washing pump 36 even when the temperature of the washing water supplied into the washing tank 31 is low in the washing step. It is possible to sufficiently wash the detergent supplied in the washing water with the high-concentration and high-temperature washing water from the beginning of the washing operation. In particular, if the introduced detergent is sufficiently dissolved in the small amount of water in the washing tank 31 before adding makeup water, washing water with a higher concentration and higher temperature from the beginning of the washing operation start. It becomes possible to perform washing with.

また、本実施の形態3の食器洗い機においては、洗剤受け部47はヒータ37の近傍に配置され、特に、残菜回収部41とは反対側にあり、かつヒータ37よりも水の流れる方向に対し上流側に配置されている。この構成により、洗浄ポンプ36の動作と共に洗浄水が高温状態のヒータ37近傍を通過し、さらに洗剤の溶解が促進され、投入された洗剤を、補給水を追加する前の洗浄槽31内の少ない水に対してでも十分に溶解させることができるため、洗浄運転開始の噴射当初から、より高濃度かつ高温の洗浄水で洗浄を行うことが可能となる。加えて、この洗浄水噴射時、洗剤受け部47はファンケース40からの勾配を有しているため、洗浄水の流れにより洗剤の溶解を更に促進するため、洗剤量が規定値よりも多い場合や溶けにくい洗剤など、洗剤の溶解条件が悪い場合でも効率的に洗剤を溶解することができる。   In the dishwasher according to the third embodiment, the detergent receiving portion 47 is disposed in the vicinity of the heater 37, particularly on the side opposite to the leftover collection portion 41 and in the direction in which water flows more than the heater 37. On the other hand, it is arranged upstream. With this configuration, the washing water passes through the vicinity of the heater 37 in a high temperature state along with the operation of the washing pump 36, and the dissolution of the detergent is further promoted. Since it can be sufficiently dissolved even in water, it is possible to perform washing with higher-concentration and high-temperature washing water from the beginning of injection at the start of the washing operation. In addition, when the cleaning water is jetted, the detergent receiving portion 47 has a gradient from the fan case 40, so that the detergent is further accelerated by the flow of cleaning water. It is possible to dissolve the detergent efficiently even when the dissolution condition of the detergent is poor, such as a detergent that is difficult to dissolve.
