[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pump automatic stop device for automatically stopping the operation of an electric pump for pumping water or remaining hot water in a bath by a water sensitive switch.

[0002]

[Prior Art]

 By the way, in ordinary households, when washing clothes, the remaining hot water in the bath may be pumped up to the washing machine. For this reason, small electric pumps are popular. However, many of these pumps are not equipped with a device that automatically stops the operation when the remaining hot water pumped to the washing machine reaches an appropriate height.

[0003]

[Problems to be solved by the device]

 Therefore, if you forget to pump up the remaining hot water in the bath, you will pump up all the remaining hot water, which is very uneconomical.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned drawbacks, and its purpose is to automatically stop the operation of the pump by using a water-sensitive switch to prevent unnecessary pumping of the remaining hot water. The first means is to provide a hose insertion part (2a) at the upper end of the cylindrical body (2) and a hollow part (2b) opened at the lower end inside. ), An air hole (2c) is formed on the outer surface from the hollow part (2b), and a water channel (2d) is formed from the upper end to the lower end, and a water sensitive switch (1) is formed on the upper part of the hollow part (2b). ) The water-sensitive switch (1) is fixed, and the positive and negative electrodes of this water-sensitive switch (1) are energized to the respective terminals at one end of the waterproof electric wire cord (3). Each end of the other end of the An automatic stop device for the pump is provided, in which the positive and negative electrodes of the plug (4) provided with the outlet (4a) are energized, and the outlet (4a) turns on and off when the water sensitive switch (1) is turned on and off. It is a summary. The second means is that a hollow body (2b) opened at the lower end is formed inside the cylindrical body (6), and an air hole (2c) is formed on the outer surface from the hollow portion (2b). The body (6) is provided with means for attaching to and detaching from the washing tub surface of the washing machine, and the water sensitive switch (1) is fixed to the upper part of the hollow portion (2b). Each of the positive and negative electrodes is energized by each terminal at one end of the waterproof wire cord (3), and each terminal at the other end of the wire cord (3) is plugged into the outlet (4a) at the back. The positive and negative electrodes of the plug (4) provided with are energized, and the main feature is the automatic stop device of the pump, in which the outlet (4a) turns on and off when the water sensitive switch (1) is turned on and off.

[0005]

[Action]

 To use it, insert the plug (4) into the outlet (C), insert the plug (P) of the pump into the outlet (4a) at the back of this plug (4), and in the first means, to the end of the hose (H). Insert the hose insertion part (2a) of the cylindrical body (2), attach the cylindrical body (2) to the tip of the hose (H), and insert the hose (H) into the washing machine to bring the cylindrical body (2) to the desired water level. Adjust the height of) by any method and start the pump operation. The remaining hot water of the bath is spouted from the water channel (2d), and when the pumped remaining hot water reaches near the cylindrical body (2), the remaining hot water enters the hollow portion (2b) and the hollow portion (2b). The remaining hot water contacts the water sensitive switch (1) inside, the outlet (4a) is turned off by the action of the water sensitive switch (1), and the operation of the pump is automatically stopped. In the second method, the columnar body (6) is fixed at the desired water level on the washing tub surface of the washing machine by means of attachment / detachment to / from the washing tub surface, the hose is inserted into the washing machine, and the pump starts operating. To do. The remaining hot water in the bath is spouted from the hose, and if the pumped remaining hot water rises and reaches the vicinity of the cylindrical body (6), the remaining hot water enters the hollow part (2b) and the water feeling in the hollow part (2b) is felt. The remaining hot water comes into contact with the response switch (1), the action of the water sensitive switch (1) turns off the power of the concentrator (4a), and the operation of the pump is automatically stopped.
