The liquid level inside can be detected.

第二の液槽２の底面には、略水平方向に第二の排液経路４が配管され、第二の開閉弁８の開閉、および、排液ポンプ１５の動作により、第二の液槽２内の液体が先端の排液口１３から機外へ排出されるようになっている。なお、第一の排液経路３と第二の排液経路４は、経路合流部１９にて合流している。 A second liquid drainage path 4 is laid on the bottom surface of the second liquid tank 2 in a substantially horizontal direction. The liquid inside 2 is discharged to the outside of the machine through a drain port 13 at the tip. The first drainage path 3 and the second drainage path 4 join together at a path junction 19 .

A second check valve 6 is arranged downstream of the drainage pump 15 . The second check valve 6 prevents backflow water and odors from entering from the downstream side.

Naturally, if the drainage pump 15 is stopped, the first liquid tank 1 can be drained preferentially.
In addition, since the first check valve 5 is provided in the first drainage path 3, even when the drainage pump 15 is in operation, the drainage from the second liquid tank 2 flows into the path joining portion 19. to the first liquid tank 1.

As a result, the liquid can be discharged in accordance with the liquid discharge processing capacity of the liquid discharge port 13, and the liquid can be prevented from overflowing in the liquid discharge port 13. FIG.

（実施の形態２）
図２は、本発明の第２の実施の形態における排液処理装置の構造図である。第一の液槽１、第二の液槽２回りの構成については、第１の実施の形態と同じであり、同一部位には同一符号を付して説明を省略する。 (Embodiment 2)
FIG. 2 is a structural diagram of a waste liquid treatment apparatus according to a second embodiment of the present invention. The configuration around the first liquid tank 1 and the second liquid tank 2 is the same as in the first embodiment, and the same reference numerals are given to the same portions, and the description thereof will be omitted.

図２において、筐体１６内において、第二の液槽２の下方に、さらに、第二の液槽２と同様の第三の液槽、第四の液槽、・・・と多くの液槽が配設されており、最下方が第ｎの液槽１０２である。 In FIG. 2, in the housing 16, below the second liquid tank 2, a third liquid tank similar to the second liquid tank 2, a fourth liquid tank, . . . The tanks are arranged, and the bottom is the nth liquid tank 102 .

第ｎの液槽１０２の底面には第ｎの液位ホース１１８が接続され、第ｎの液位ホース１１８先端に設けられた第ｎの液位センサー１１２により、第ｎの液槽１０２内の液位を検知することができる。 An n-th liquid level hose 118 is connected to the bottom surface of the n-th liquid tank 102, and the n-th liquid level sensor 112 provided at the tip of the n-th liquid level hose 118 detects the inside of the n-th liquid tank 102. Liquid level can be detected.

第ｎの液槽１０２内の排液は、第ｎの排液経路１０４に設けられた第ｎのフィルター１１０を介し、第ｎの開閉弁１０８の開閉、および、第ｎの排液ポンプ１１５の動作により、第ｎの逆止弁１０６を経由して、排液口１３から機外へ排出されるようになっている。 Drainage in the n-th liquid tank 102 passes through the n-th filter 110 provided in the n-th drainage path 104, the opening and closing of the n-th on-off valve 108, and the operation of the n-th drainage pump 115. By this operation, the liquid is discharged out of the machine through the drain port 13 via the n-th check valve 106 .

また、第一の排液経路３は最下方まで降りており、第二の液槽２以下すべての液槽の排液経路と合流しており、最下方では経路合流部１１９で第ｎの排液経路１０４と合流している。 In addition, the first drainage path 3 descends to the lowest point and joins the drainage paths of all the liquid tanks below the second liquid tank 2. It merges with the liquid path 104 .

また、第ｎの排液ポンプ１１５は、最下方の第ｎの液槽１０２から第一の液槽の最高液位に相当する揚程以上の吸込能力を持っている。 Also, the n-th liquid drain pump 115 has a suction capacity from the lowermost n-th liquid tank 102 to a lift equal to or higher than the highest liquid level of the first liquid tank.

以上の構成にて、第一の液槽１の排液時においても、各液槽の排液経路に設けた排液ポンプ、例えば、第ｎの排液経路１０４に設けた第ｎの排液ポンプ１１５を駆動することで、第ｎの液槽１０２の排液を優先的に行うことができる。当然の事ながら、第ｎの排液ポンプ１１５を停止すれば、第一の液槽１の排液を優先的に行うこともできる。 With the above configuration, even when the first liquid tank 1 is drained, the drain pump provided in the liquid drain path of each liquid tank, for example, the n-th drain liquid provided in the n-th drain path 104 By driving the pump 115, the n-th liquid tank 102 can be drained preferentially. Naturally, if the n-th drainage pump 115 is stopped, the first liquid tank 1 can be drained preferentially.

また、複数の液槽から同時に排液する場合でも、各液槽の排液経路に配設した逆止弁の作用や、制御装置１４により各液槽の排液経路に配設した各排液ポンプの駆動を制御し、および、モータ回転数を調整することで、他の液槽への逆流も無く、排液口１３における液の溢れを防止することができる。 Even when the liquid is discharged from a plurality of liquid tanks at the same time, the action of the check valves arranged in the liquid discharge paths of the respective liquid tanks and the control device 14 for each of the liquid discharges arranged in the liquid tank drainage paths By controlling the drive of the pump and adjusting the number of revolutions of the motor, it is possible to prevent the liquid from overflowing at the drainage port 13 without backflow to other liquid tanks.

以上のように、本実施の形態においては、複数の排液ポンプは、第一の液槽の最高液位に相当する揚程以上の吸込能力を持つとともに、制御装置１４は、複数の液槽の液位を検知して、排液口１３の排液処理能力に応じて、第一の開閉弁７あるいは複数の開閉弁、および、複数の排液ポンプが動作する優先度を決定する構成とすることにより、排液口１３における液の溢れを防止して、複数の液槽の任意の液槽から優先的に排液できる、もしくは、複数の液槽からの排液を同時に行えるため、効率的な排液処理を実現することができる。 As described above, in the present embodiment, the plurality of liquid drainage pumps have a suction capacity equal to or higher than the head corresponding to the maximum liquid level of the first liquid tank, and the control device 14 controls the liquid tanks. The liquid level is detected, and the priority of operation of the first on-off valve 7 or a plurality of on-off valves and a plurality of drainage pumps is determined according to the drainage processing capacity of the drainage port 13. As a result, it is possible to prevent the liquid from overflowing from the drain port 13, and to drain the liquid preferentially from an arbitrary one of the plurality of liquid tanks, or to drain the liquid from the plurality of liquid tanks at the same time, which is efficient. can be realized.

なお、本実施の形態では、排液処理装置の排液について説明しなかったが、排液は洗濯の排液であればよい。従って、衣類を洗濯した排液でもよいし、他の排液装置であってもよい。従って、排液処理装置は、縦型洗濯機やドラム式洗濯機に代表される、衣類を洗濯する洗濯機であってもよい。洗濯機である場合、洗濯機は複数の液槽を備えていればよく、第一の液槽は、縦型の液槽であってもよいし、回転ドラムであってもよい。また、第二の液槽も、縦型の液槽であってもよいし、回転ドラムであってもよい。 In this embodiment, the waste liquid of the waste liquid processing device is not described, but the waste liquid may be washing waste liquid. Therefore, it may be used for washing clothes, or may be another drainage device. Therefore, the waste liquid treatment apparatus may be a washing machine for washing clothes, typified by vertical washing machines and drum-type washing machines. In the case of a washing machine, the washing machine may have a plurality of liquid tanks, and the first liquid tank may be a vertical liquid tank or a rotating drum. The second liquid tank may also be a vertical liquid tank or a rotating drum.

本開示は、複数の液槽を有する排液処理装置に適用可能である。具体的には、縦型洗濯機、ドラム式洗濯機、二槽式洗濯機などに、本開示は適用可能である。 INDUSTRIAL APPLICABILITY The present disclosure is applicable to a waste liquid treatment apparatus having multiple liquid tanks. Specifically, the present disclosure is applicable to vertical washing machines, drum washing machines, twin-tub washing machines, and the like.
