Referring to Fig. 1, the upper drain washing machine 100 according to the embodiment of the present invention is described.
As shown in Figure 1, according to the upper drain washing machine 100 of the embodiment of the present invention, comprising: housing, washtub, upper drainpipe, draining pump 40, level sensor 10, water intaking valve 20 and controller 30.
Specifically, drive motors and washtub can all be located in housing.Upper drainpipe is located in housing, to be discharged the water in washtub by washing machine top.Draining pump 40 to be located in housing and to be connected with upper drainpipe, to make water by upper drainpipe draining.Level sensor 10 is located in housing for detecting the water level in washtub.Such as, level sensor 10 can be located in washtub, detects the water level in washtub, or be communicated with in washtub that the water level in washtub is detected.
Water intaking valve 20 be located on housing with when opening to water filling in washtub.Such as, when washing machine 100 normally works, when the washing of washing machine 100 and rinse stage start, water intaking valve 20 is opened, and with to water filling in washtub, in washing, rinsing and water smoking, water intaking valve 20 is in closed condition.Controller 30 is connected respectively with level sensor 10 and draining pump 40, when exceeding predetermined altitude with the water level detected in washtub at level sensor 10, starts draining pump 40 outwards draining.
According to the upper drain washing machine 100 of the embodiment of the present invention, level sensor 10 is utilized to detect height of water level in washtub, when in washtub, height of water level exceedes predetermined altitude, controller 30 will control draining pump 40 outwards draining, avoid the water when water level is too high in washtub outwards to be overflowed by washtub, eliminate electrical safety hidden danger, improve safety in utilization and the user satisfaction of drain washing machine 100.
As shown in Figure 1, according to some embodiments of the present invention, predetermined altitude can be distance washtub upper end 2-6cm, and the scheduled time can be 3-7min.When the water level that level sensor 10 detects in washtub exceedes predetermined altitude, controller 30 will start draining pump 40 outwards draining, until the water level in washtub is lower than predetermined altitude; When the water level that level sensor 10 detects in washtub exceedes predetermined altitude to the scheduled time, controller 30 cuts off the connection of drive motors and power supply, quits work to make upper drain washing machine 100.
Such as, when predetermined altitude is for distance washtub upper end 4cm, the scheduled time, when being 5min, when the water level that level sensor 10 detects in washtub exceedes predetermined altitude, controller 30 started draining pump 40, water in washtub is discharged, to make in washtub water level lower than predetermined altitude; When the water level that level sensor 10 detects in washtub exceedes predetermined altitude to the scheduled time, controller 30, by the connection of force disconnect drive motors and power supply, makes drain washing machine 100 quit work.Thus, can avoid spilling water accident occurring, the use safety of drain washing machine 100 in impact.
According to one embodiment of present invention, controller 30 is located at the top of housing, so that user operates upper drain washing machine 100.According to one embodiment of present invention, controller 30 is connected with water intaking valve 20, for controlling the opening and closing of water intaking valve 20.Thus, the Automated condtrol realizing drain washing machine 100 is convenient to.
Referring to Fig. 2, the method for controlling water level according to the upper drain washing machine of the embodiment of the present invention is described.
As shown in Figure 2, according to the method for controlling water level of the upper drain washing machine of the embodiment of the present invention, comprise the following steps:
S100: in washtub during water filling, detect the water level in washtub.Particularly, when upper drain washing machine is in washtub charging state, level sensor will detect the water level in washtub;
S200: when detecting that the water level in washtub exceedes predetermined altitude, opening water discharge pump is with outside draining.Particularly, when the water level that level sensor detects in washtub exceedes predetermined altitude, controller will start draining pump with outside draining, until the water level that level sensor detects is lower than predetermined altitude.
According to the method for controlling water level of the drain washing machine of the embodiment of the present invention, level sensor is utilized to detect height of water level in washtub, when in washtub, height of water level exceedes predetermined altitude, controller will control the outside draining of draining pump, avoid the water when water level is too high in washtub outwards to be overflowed by washtub, eliminate electrical safety hidden danger, improve safety in utilization and the user satisfaction of drain washing machine.
Further, when detecting that the water level in washtub exceedes predetermined altitude to the scheduled time, cut off the power supply of drive motors.Particularly, when the water level that level sensor 10 detects in washtub exceedes predetermined altitude to the scheduled time, controller 30, by the connection of force disconnect drive motors and power supply, to avoid spilling water accident occurs, affects use safety.
As shown in Figure 2, according to some embodiments of the present invention, the scheduled time can be 3-7min, and predetermined altitude can be distance washtub upper end 2-6cm.When the water level that level sensor 10 detects in washtub exceedes predetermined altitude, controller 30 will start draining pump 40 outwards draining, until the water level in washtub is lower than predetermined altitude; When the water level that level sensor 10 detects in washtub exceedes predetermined altitude to the scheduled time, controller 30 cuts off the connection of drive motors and power supply, quits work to make upper drain washing machine 100.
Such as, when predetermined altitude is for distance washtub upper end 4cm, the scheduled time, when being 5min, when the water level that level sensor 10 detects in washtub exceedes predetermined altitude, controller 30 started draining pump 40, water in washtub is discharged, to make in washtub water level lower than predetermined altitude; When the water level that level sensor 10 detects in washtub exceedes predetermined altitude to the scheduled time, controller 30, by the connection of force disconnect drive motors and power supply, makes drain washing machine 100 quit work.Thus, can avoid spilling water accident occurring, the use safety that in impact, drain washing machine 100 stops.
