Description

本発明は洗濯機の分野に関し、特に槽間に水を有さない洗濯機および制御方法である。   The present invention relates to the field of washing machines, in particular washing machines and control methods without water between the baths.

既存のパルセータ式洗濯機は、内槽に透水孔を有し、内外槽間は通じる。内槽は洗濯槽であり、外槽は水受け槽であるが、内槽および外槽の側壁間に満たされるこの部分の水は洗濯に関与しない。洗濯に関与するのは内槽中の水のみであり、これにより水資源の浪費は比較的多くなる。他に、内外槽間の水が過度に多いと、洗濯液中の洗剤／粉末洗剤の濃度も低下する。これと同時に、水流が内槽、外槽の間で頻繁に出入りするため、使用し続けると、内槽および外槽の側壁間の領域は汚れた空間になり、水道水の水垢、粉末洗剤の遊離物、衣類のセルロース、人体の有機物、衣類から持ち込まれる埃および細菌が、極めて容易に内槽および外槽の側壁間に溜まる。これらのカビは、長く使用した洗濯機内部に蓄積した大量の汚れであり、効果的に除去することができないため、繁殖したものである。これらの使用者から見えない汚れを除去しない場合、次の洗濯で、細菌が衣類に付着して人体にもたらし、交差感染の問題を引き起こす。   The existing pulsator type washing machine has a water-permeable hole in the inner tank, and the communication between the inner and outer tanks is conducted. The inner tank is a washing tank, and the outer tank is a water receiving tank, but this portion of water filled between the inner tank and the side wall of the outer tank does not participate in the washing. Only the water in the inner tub is involved in the washing, which results in relatively high waste of water resources. In addition, if there is too much water between the inner and outer tubs, the concentration of detergent / powder detergent in the washing liquid will also be reduced. At the same time, since the water flow frequently moves between the inner tank and the outer tank, the area between the inner tank and the side wall of the outer tank becomes a dirty space when it is used continuously. Free matter, cellulose of clothes, organic matter of human body, dust and bacteria carried from clothes extremely easily accumulate between the side walls of the inner tank and the outer tank. These molds are a large amount of dirt accumulated inside the washing machine used for a long time and can not be removed effectively, so they are propagated. At the next wash, if they do not remove stains that are not visible to these users, bacteria will adhere to the clothing and cause it to the human body causing cross-infection problems.

中国特許第２００４２０１０７８９０．８号明細書は全自動洗濯機に関し、主に筐体、洗濯脱水槽、水受け槽および駆動装置を含む。水受け槽は洗濯脱水槽の外側に取り付けられて、筐体と固定接続され、水受け槽の内壁底面と洗濯脱水槽の外壁底面との間に密封装置が設けられ、密封装置内に密封空洞が形成される。洗濯脱水槽の外側壁に貫通孔は無く、底部に密封空洞と通じる排水孔が設けられ、水受け槽に排水管と通じる第１排水孔が設けられ、排水管に排水弁が設けられる。水受け槽は吊棒により筐体と固定接続される。吊棒の一端は筐体上端の内壁と接続され、もう一端は水受け槽の外壁と接続される。しかし、長時間稼働すると、密封構造が長時間の稼働で摩耗するため、容易に摩耗による漏水が生じる。水質が比較的劣り、含砂量が比較的高い場合、使用寿命は大幅に短くなり、有すべき機能を発揮することができなくなる。洗濯容量が多い状態での使用にも適応せず、信頼性が比較的劣る。   Chinese Patent No. 200420107890.8 relates to a fully automatic washing machine, mainly including a housing, a washing and dewatering tank, a water receiving tank and a driving device. The water receiving tank is attached to the outside of the washing and dewatering tank and fixedly connected to the housing, and a sealing device is provided between the inner wall bottom surface of the water receiving tank and the outer wall bottom surface of the washing and dewatering tank. Is formed. There is no through hole in the outer wall of the washing and dewatering tank, the bottom is provided with a drainage hole communicating with the sealed cavity, the water receiving tank is provided with a first drainage hole communicating with the drainage pipe, and the drainage pipe is provided with a drainage valve. The water receiving tank is fixedly connected to the housing by a lifting rod. One end of the hanging rod is connected to the inner wall of the upper end of the case, and the other end is connected to the outer wall of the water receiving tank. However, when it is operated for a long time, since the sealing structure is worn out for a long time, water leakage by abrasion easily occurs. If the water quality is relatively poor and the amount of sand contained is relatively high, the service life will be greatly shortened and it will not be possible to exhibit the function to be possessed. It is not suitable for use in the state with a large washing capacity, and the reliability is relatively poor.

このことを考慮して、本発明を示す。   Taking this into consideration, the present invention is illustrated.

図１、図２に示すように、本発明の前記槽間に水を有さない洗濯機は、内槽１、外槽４を含む。内槽１の上部における上縁の近くに複数の放水孔２が設けられ、内槽１の底部に少なくとも１つの内槽排水口３が設けられる。外槽４底部に内槽排水口を閉じることができる伸縮式排水弁１０が設けられ、外槽４底部に外槽排水口５が設けられ、前記外槽排水口５に洗濯機の排水管路６が設けられる。   As shown in FIG. 1 and FIG. 2, the washing machine having no water between the tanks according to the present invention includes an inner tank 1 and an outer tank 4. A plurality of water discharge holes 2 are provided near the upper edge at the top of the inner tank 1, and at least one inner tank drainage port 3 is provided at the bottom of the inner tank 1. A telescopic drain valve 10 capable of closing the inner tank drainage port is provided at the bottom of the outer tank 4, an outer tank drainage port 5 is provided at the bottom of the outer tank 4, and the drainage channel of the washing machine is provided at the outer tank drainage port 5. 6 is provided.

洗濯時、内槽１はロックされ、伸縮式排水弁１０は内槽排水口３を閉じ、内槽１中に水を有し、内外槽間に水は有さない。排水時、伸縮式排水弁１０は内槽排水口を開き、内槽１内の大部分の水は内槽排水口３を通って内槽１から排出され、さらに外槽排水口５および洗濯機の排水管路６を通って排出される。脱水時、内槽１はロックが解除され、内槽１が回転して脱水する。脱水時に放出される水は、遠心力の作用により上に運動し、放水孔２を通って内槽から排出され、内槽、外槽間に到り、さらに外槽排水口５および洗濯機の排水管路６を通って排出される。   At the time of washing, the inner tub 1 is locked, the telescopic drain valve 10 closes the inner tub drainage port 3 and has water in the inner tub 1 and no water between the inner and outer tubs. When draining, the telescopic drain valve 10 opens the inner tank drainage port, most of the water in the inner tank 1 is drained from the inner tank 1 through the inner tank drainage port 3, and the outer tank drainage port 5 and the washing machine Drained through the drain line 6 of the At the time of dewatering, the lock of the inner tank 1 is released, and the inner tank 1 rotates to dewater. The water released at the time of dewatering moves upward by the action of centrifugal force and is discharged from the inner tank through the water discharge hole 2 to reach between the inner tank and the outer tank, and further, the outer tank drain 5 and the washing machine It is drained through drain line 6.

前記外槽４および前記内槽１は同心で設置され、内槽排水口３の中心から内槽１の中心までの距離は、外槽排水口５の中心から外槽４の中心までの距離と同じである。内槽の排水時、内槽排水口３は外槽排水口５に正対し、水流は内槽１から出て、直接外槽排水口５を通過し、洗濯機の排水管路６に進入して排出される。排水は順調であり、内外槽間に停滞する時間は短く、水は先に内外槽間に排出される必要はなく、外槽排水口５に流れる。好ましくは、前記外槽排水口５の直径は前記内槽排水口３の直径より大きく、水流が内外槽間で停滞するのを防止し、汚れが外槽内壁に付着するのを防止する。   The outer tank 4 and the inner tank 1 are installed concentrically, and the distance from the center of the inner tank drain 3 to the center of the inner tank 1 is the distance from the center of the outer tank drain 5 to the center of the outer tank 4 It is the same. When draining the inner tank, the inner tank drainage port 3 faces the outer tank drainage port 5, the water flow comes out of the inner tank 1, passes directly through the outer tank drainage port 5, and enters the drainage pipeline 6 of the washing machine Discharged. The drainage is smooth, the stagnation time between the inner and outer tanks is short, and the water does not have to be discharged first between the inner and outer tanks, and flows to the outer tank drain 5. Preferably, the diameter of the outer tank drainage port 5 is larger than the diameter of the inner tank drainage port 3 so as to prevent the water flow from stagnating between the inner and outer tanks and prevent the contamination from adhering to the inner wall of the outer tank.

上記洗濯機は洗濯時、内外槽間に水を有さず、洗濯水を節約することができ、洗濯のたびにおおよそ２０％前後を節約する。排水時、大部分の水は下部の排水口から排出され、糸屑、土砂はこれに伴って排出され、内槽内に堆積することはない。さらに脱水および洗濯時、内槽と、内槽排水口を閉じる密封構造（伸縮式排水弁）との間は相対運動せず、摩耗を防止する。   The washing machine has no water between the inner and outer tubs during washing, can save washing water, and saves about 20% each time washing. When draining, most of the water is drained from the lower drainage port, and lint and soil are drained along with it and will not deposit in the inner tank. Furthermore, during dehydration and washing, relative movement does not occur between the inner tank and the sealing structure (telescopic drain valve) for closing the inner tank outlet, thereby preventing wear.

前記外槽４に空気室７が設置され、前記空気室７は外槽４の内部または外部のいずれに設置してもよい。本発明において、好ましくは、空気室７は外槽４の外部に設置され、内槽１の取付に影響を及ぼさず、内槽１の容量を可能な限り増大させる。前記空気室７は内槽と第２管路を介して通じ、内槽１中に水を有するとき、水は空気室に進入することができる。空気室７に圧力センサ１９が接続され、圧力センサ１９が空気室７内の空気の圧力を測定することにより、内槽中の水位を測定する。このような測定方法による水位の測定は、構造が簡単で、測定結果は正確である。   An air chamber 7 may be installed in the outer tank 4, and the air chamber 7 may be installed either inside or outside the outer tank 4. In the present invention, preferably, the air chamber 7 is installed outside the outer tank 4 and does not affect the attachment of the inner tank 1 to increase the capacity of the inner tank 1 as much as possible. The air chamber 7 communicates with the inner tank via the second conduit, and when water is contained in the inner tank 1, the water can enter the air chamber.
