Abstract

(57) [Summary] [Objective] The present invention relates to improvement of a water absorption hose of a pump of a washing machine or the like. [Structure] A backflow prevention valve is provided at both ends of the water suction hose of a washing machine that absorbs water from a water tank, etc., so that the liquid is always filled to eliminate wasted time such as air discharge when the washing pump is operating. is there.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a water absorbing portion for absorbing water from a water tank or the like of a high pressure cleaning device.

[0002]

[Prior art]

 In the normal cleaning work, the tip of the extension hose for absorbing water is introduced into the water tank, and it is as shown in the image of the overall view of Fig. 1. At this time, conventionally, the air component in the water absorption extension hose was discharged from the injection nozzle and then the cleaning operation was started.

[0003]

[Problems to be solved by the device]

 The waiting time required to discharge the air in the water absorption extension hose described above is a waste of 5 to 8 minutes for a small pump.

[0004]

[Means for Solving the Problems]

 In order to make the above-mentioned air discharge time zero, a washing machine having an injection nozzle and a pump provided with a removable water absorption hose is equipped with a backflow prevention valve at both ends of the water absorption hose to normally remove the liquid. It provides a cleaning device characterized by being configured so that it can be filled.

[0005]

[Action]

 Since the backflow prevention valves are installed at both ends of the water absorption hose, the hose is always filled with liquid to keep the page (2). When necessary, insert one end into the water tank and connect the other to the water intake on the pump side. However, if the pump is driven, there is no air discharge, so water is immediately sucked up and high-pressure water is discharged from the injection nozzle.

[0006]

【Example】

 The configuration will be described based on the drawings in which the present invention is implemented. FIG. 1 shows an overall implementation of the present invention, in which a water transfer hose 3 is connected to a moving carriage 1 containing a pump motor and the like and a water intake 4 to absorb water from a water tank 8. The injection nozzle 9 is connected to the discharge port 5. Reference numeral 6 is a motor switch, 7 is a running wheel, and in the present embodiment, it is a two-wheel swivel vehicle, which is formed compactly. 10 is a filter attached to the end of the water-absorbing hose 3 described above, which is put in a water tank such as a toilet. Reference numeral 21 denotes a lid, and the upper surface of the upper portion of the storage box 2 is formed so as to be openable.

FIG. 2 shows a state in which the water suction hose 3 is separated from the coupler 17 of the water suction port 4 of the pump 18. The check valve on the pump mounting side of the water suction hose 3 has a slightly protruding central part, and a spring is provided inside to crimp it outward. The check valve on the front end side of the water suction hose 3 has a ball shape, and is coiled outward by a coil spring 13. Therefore, the part of the liquid filled and held inside the water-absorbing hose 3 is retained.

The coupler 17 provided at the water inlet 4 of the pump 18 has a retaining ring 16 inside the outer cylinder, and is engaged and fixed to the outer solid groove 14 of the outer cylinder of the check valve 11.

FIG. 3 shows a state in which they are engaged and connected. The projecting piece 15 located at the center of the coupler 17 presses the end portion of the check valve 11 and presses the mutual springs to flow the liquid. Open up. Therefore, when the tip of the water suction hose 3 is put into the water tank as shown in FIG. 1 and the pump 18 is operated, the ball of the tip check valve 12 in FIG. Work to suck up. At this time, since the water absorbing hose 3 is filled with the liquid (3), it is not necessary to discharge air.

FIG. 4 shows a cross section of the movable carriage 1 in which the respective parts of the washing machine are installed. The motor 19 and the pump 18 are installed in the lower part of the second storage box, and the injection nozzle parts, the hose and other parts are housed in the upper part.

[0011]

【effect】

 As described above, when the water in the water tank or the like is used, the water is absorbed, and the water absorption hose is filled with liquid.Therefore, wasteful time such as air discharge can be eliminated and efficient cleaning work can be performed. It was
