The specific embodiment
Below just describe embodiments of the invention in detail, its example is shown in the drawings, and identical in the text Reference numeral is represented components identical.Below embodiment is described to be explained with reference to the drawings the present invention.
In Fig. 1, comprise cabinet 10, door 11, water drum 20, rotating cylinder 21 and drive motors 22 according to the tumbling-box washing machine 100 of embodiment.Door 11 is installed on the surface of cabinet 10 to open and close.Water drum 20 is arranged in cabinet 10, comprises the cylindrical shape of opening towards door 11.Rotating cylinder 21 is rotatably installed in the water drum 20.Drive motors 22 drives rotating cylinder 21.
Rotating cylinder comprises the lifter 25 that is installed on rotating cylinder 21 side wall inner surfaces, and when rotating cylinder 21 rotations, the clothing that lifter 25 is used for being placed on rotating cylinder 21 bottoms moves up.Rotating cylinder also comprises a plurality of holes 26 that are positioned on its sidewall, is used for water is infeeded rotating cylinder 21 from water drum 20.
Tumbling-box washing machine also comprises water supply pipe 30, and its inside is arranged on the top of cabinet 10, be used for water is infeeded water drum 20, and detergent container 33, described detergent container 33 is arranged on the precalculated position of door 11 tops, and described door 11 is connected to water supply pipe 30.
Water drum also comprises the water supply hole 23 that is positioned on its roof.Wherein the end of water supply pipe 30 is connected to water supply hole 23.Water drum also is included in the osculum 24 that water drum 20 bottoms form, and is used for water is discharged from water drum 20 by osculum 24.
Draining pump 40 is installed in the bottom of cabinet 10, is used for from water drum 20 drainings.Suction tube 41 is arranged on the predetermined position of draining pump 40, is used for water is extracted into draining pump 40 from water drum 20, and adjutage 42 is arranged on the predetermined position of draining pump 40, is used for water is discharged from draining pump 40.First drainpipe 31 is connected to suction tube 41 with the osculum 24 of water drum 20.Second drainpipe 32 is connected to adjutage 42 at first end, is extended to the outside of cabinet 10 simultaneously at second end.
Tumbling-box washing machine 100 also comprises level sensing unit 50, is used for detecting the water level of water drum 20.Level sensing unit 50 comprises level sensor flexible pipe 51 and level sensor 54.The lower end of level sensor flexible pipe 51 is connected to the suction tube 41 of draining pump 40.Level switch 54 is installed in the upper end of level sensor flexible pipe 51, is used for the air pressure of sensed water level sensing flexible pipe 51.Level sensor flexible pipe 51 comprises minor diameter 52 and large-diameter portion 53.Level switch 54 is installed in upper end in minor diameter 52.Large-diameter portion 53 is connected to the lower end of minor diameter 52.
Operation according to the tumbling-box washing machine that has level sensing unit 50 100 of the embodiment of the invention below will be described.
At first, laundry item is placed in the rotating cylinder 21 that is rotated by drive motors 22.When rotating cylinder 21 rotation, be positioned at the lifter 25 that the clothing of rotating cylinder 21 bottoms is installed on rotating cylinder 21 side wall inner surfaces and move up, then because the bottom that gravity is fallen rotating cylinder 21.When clothing is moved upward and falls rotating cylinder 21 bottoms, between clothing, produce impact force and friction, thus cleaning clothes.
Washings infeed water drum 20 by water supply pipe 30.Because water supply pipe 30 is connected to detergent container 33, cleaning agent, is dissolved in the water by in the water supply water drum 20 simultaneously with water.For an amount of water of supply in water drum 20, level sensing unit 50 detects the water level that is contained in the rotating cylinder 21.
According to the present invention, the lower end of level sensor flexible pipe 51 is connected to the suction tube 41 of the draining pump 40 that is installed on the cabinet 10, and this point is different with traditional level sensor flexible pipe, and the lower end of traditional level sensor flexible pipe is connected to water drum.Therefore, level sensor flexible pipe 51 can not liked the influence in the vibrations of the operating period of drive motors 22 generation.
Because level sensor flexible pipe 51 bottoms comprise large-diameter portion 53, respond same SEA LEVEL VARIATION, level sensor flexible pipe 51 of the present invention has bigger pressure than the traditional level sensor flexible pipe with constant diameter to be changed, thereby makes accurately sensed water level of level switch 54.
Because the pressure of compressed air acts on the water surface of large-diameter portion 53, the water surface of large-diameter portion 53 is lower than the water surface of water drum 20, and atmospheric pressure acts on this water surface.Because large-diameter portion 53 comprises predetermined length, when the water level of water drum 20 arrived maximum, this length was enough to prevent that the water in the large-diameter portion 53 from arriving minor diameter 52, therefore, impurity such as fine hair can not stop up minor diameter 52, thereby prevents the maloperation of level sensing unit 50.Large-diameter portion 53 comprises about 10cm or more length.
From above description, clearly, the invention provides a kind of tumbling-box washing machine with level sensing unit.According to the present invention, the level sensor flexible pipe of level sensing unit is connected to the predetermined position that is installed in the draining pump on the cabinet, prevents that the level sensor flexible pipe from damaging or fragmentation owing to vibrations.In addition, the level sensor flexible pipe comprises large-diameter portion in its underpart, makes that water level is accurately detected, and prevents that the level sensor flexible pipe from being stopped up by impurity, thereby prevents the maloperation of level sensing unit.
Although illustrated and described some embodiment of the present invention, those skilled in the art will appreciate that, can carry out various variations to these embodiment under the situation that does not depart from principle of the present invention and essence, its scope is limited in claim and the equivalent thereof.
