  An embodiment for carrying out the liquid supply apparatus of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows the configuration of the liquid supply apparatus of the present invention. The suction tube (3) has one end communicating with the storage tank (1) for storing the liquid (2) and the other end communicating with the pump (4). Aspirate. The supply tube (7) has one end communicating with the pump (4) and transfers the liquid pumped by the pump to the injection tank (8). The tip opening (16) on the injection tank side of the supply tube is held at an arbitrary position above the opening of the injection tank by the manual holding means (9).

  The liquid (2) is not particularly limited as long as it has a viscosity that can be sucked and pumped by a pump and does not cause an interaction such as a chemical reaction with a tube for transferring the liquid. Is used as a detergent injection machine for washing machines, liquid detergents, softeners, and liquid detergents containing softeners are applicable.

  As long as the storage tank (1) is a container suitable for liquid storage, the material and size are not particularly limited, and a highly versatile 18 liter polyethylene container can also be used. The tip of the suction tube (3) is immersed to the bottom of the tank so that the liquid in the storage tank can be sucked without remaining.

  The suction tube (3) and the supply tube (7) are made of resin, for example, any of fluororesin (polytetrafluoroethylene), nylon, vinyl chloride, polybutene, polyethylene, polypropylene, fluororubber, silicone rubber, and natural rubber It is desirable to use these materials. By adopting these materials having excellent flexibility, it is possible to make free piping, and it is possible to easily cope with the size of the storage tank and the injection tank and their arrangement. Further, these materials have little durability and safety with little interaction with liquid. However, it is not limited to these materials, and other materials can be used.

  The pump (4) is not particularly limited as long as it is for transferring a liquid, and a metering pump, a line pump, a tube pump, and the like can be used. However, when using a line pump or the like that does not have a quantitative function, it is preferable to incorporate a timer for operating the pump for a certain period of time in the pump control unit in order to transfer a predetermined amount of liquid.

  The operation of the pump (4) is controlled by the control unit (5), but it is preferable to prepare the operation unit (6) separately from the control unit (5) so that the control unit (5) can be remotely operated. The operation unit (6) is connected to the control unit (5) by a cable (10), but can be operated by radio (wireless remote control) without using a cable. By remotely operating the operation unit, the distance traveled by the worker working near the injection tank (8) can be reduced, and workability can be improved. However, the remote operation of the pump by the operation unit (6) should be determined according to the work situation. Instead of the remote operation by the operation unit (6), an operation button is provided on the control unit (5) to directly connect the control unit. It is also possible to operate.

  The manual holding means (9) is for holding the tip opening (16) on the injection tank side of the supply tube (7) at an arbitrary position above the opening of the injection tank. The manual holding means makes it possible to arrange the supply tube according to the size and position of the pouring tub.

In addition, the manual holding means can change the position of the tip opening (liquid outlet) (16) on the injection tank side of the supply tube according to the work situation, so that, for example, liquid detergent is injected into the washing machine. In this case, the liquid outlet is held above the opening of the washing tub, and after the detergent has been injected, the liquid outlet is moved to another position so as not to interfere with the work such as closing the lid of the washing machine. And can be stored.

  One of the manual holding means (9) is a flexible cylindrical member that covers at least the vicinity of the tip of the supply tube on the side of the injection tank, and has a structure in which the end opposite to the injection tank is fixed. It can be. As a result, the manual holding means can stably hold the tip opening of the supply tube on the injection tank side at an arbitrary position.

  The end (root) (19) opposite to the injection tank of the manual holding means (9) should be fixed to the support section (13) of the fixing stand (11) installed on the wall near the injection tank. Can do. However, the fixed stand is not limited to the type installed on the wall, but may be a type that is independent from the floor. Moreover, a commercially available stand can be used as the fixing stand, and for example, a dryer stand for fixing the dryer in the vicinity of the washing machine can be used. The stand for the dryer includes a direct attachment type in which the stand is attached to the washing machine and a self-supporting type in which the stand is placed on the floor, and any type can be used as a fixed stand. When using these commercially available stands, a support part is installed by processing as needed.

The fixing stand (11) can be provided with an attachment portion (14) for fixing the operation unit (6) for remotely operating the pump (4). By fixing the operation unit (6) to the fixed stand (11), the injection tank (8), the manual holding means (9), and the operation unit (6) can be combined in one place, and the movement of the operator is reduced. And work can be carried out efficiently.

  The flexible cylindrical member used for the manual holding means (9) should be a pipe made by processing a thin stainless steel welded tube with a thickness of 0.2 to 0.4 mm into a bellows shape so that it can be bent freely by hand. For example, the trade name “Flexible Tube Benly Kang” manufactured by Sanei Faucet Co., Ltd. is available. In addition, Mori Kogyo Co., Ltd. trade name “Flexible tube”, Sangensensen Kogyo Co., Ltd. trade name “Flexible tube” and pipes with flexible tubes covered with stainless steel, for example, Daiwa Denshi Co. The trade name “Blade Covered Flexible” can be used.

  In addition, the manual holding means (9) may be attached to the vicinity of the tip of the supply tube on the injection tank side and include a suction disk or a magnet. The tip of the supply tube on the injection tank side is fixed at an arbitrary position using the suction force of the suction disk or magnet.

  Hereinafter, the case where the liquid supply apparatus of the present invention is used as a detergent injecting machine for injecting a liquid detergent into a household washing machine will be described in detail as an example. However, the present invention is limited to the following example. is not.

FIG. 2 shows a structure in which the manual holding means (9) fixes the tip opening (liquid outlet) (16) of the supply tube (7) on the injection tank side. A root portion (19) which is an end portion of the manual holding means (9) opposite to the injection tank is attached to the joint portion (15) of the fixed stand (11). The fixing stand (11) attaches and fixes the attachment portion (12) to the wall (20) near the injection tank (8). The inside of the support portion (13) and the manual holding means (9) has a hollow structure (FIG. 3), and the supply tube (7) inserted from the insertion hole (17) provided in the middle of the support portion (13) is supported. It passes through the inside of the part (13) and the manual holding means (9) and communicates with the tip of the manual holding means. Further, it is preferable that the distal end opening (16) of the supply tube protrudes about 10 mm from the distal end of the manual holding means (9). This is for injecting the liquid from the supply tube into the injection tank without touching the manual holding means (9). That is, the supply tube uses a material having a small surface tension with respect to the liquid, prevents the liquid from remaining in the tube, and improves the liquid breakage when injecting from the tube tip to the injection tank. This is to prevent the liquid from touching the manual holding means so as not to impair such effects. However, since this function is an additional function of the present invention, it is not always necessary.

  The pump (4) used was a tube pump of a type that extrudes the liquid in the pipe by squeezing an elastic tube by the rotation of the rotor. Since the volume pushed out by one rotation of the rotor is constant, it can be used as a precise metering machine, and it is suitable for use in chemical plants that supply detergents and dispense small quantities of liquids. The product name “Tube Pump” manufactured by Welco was used as the pump. The pump was installed at a height of about 1.6 m from the floor. This is to reduce the load on the pump for pumping the detergent by fixing the pump at a position higher than the height of the liquid outlet (16).

  As the manual holding means (9), a product name “Flexible Tube Benlycan” manufactured by Sanei Water Works Co., Ltd. was used as a pipe formed by processing a thin stainless steel welded tube into a bellows shape and allowing it to be bent freely by hand. The suction tube and the supply tube were made of polypropylene and had an outer diameter of 6 mm and an inner diameter of 4 mm.

  The operation unit (6) was attached to the operation unit attachment part (14) of the fixed stand (11). The operation unit (6) is for remotely operating the control unit (5) of the pump and includes a power button and a switching button for selecting the amount of detergent to be supplied (FIG. 5). The switch button allows the amount of detergent to be selected from three levels of “low”, “standard”, and “high”, and the pump operates so that the selected amount of detergent can be supplied. The supply amount of the detergent is controlled by the operation time of the pump, and is controlled by a timer built in the pump control unit (5). In addition, a manual switching button and a manual start button are provided so that the amount of liquid can be arbitrarily set. The operation unit (6) and the pump control unit (5) are connected by a cable (10) and can be remotely operated by the operation unit (6).

  In the present embodiment, the operation unit (6) is operated on the fixed stand (11) because it is more efficient to install the operation unit (6) near the pouring tub (8) (corresponding to the washing tub of the washing machine). Although the unit mounting portion (14) is provided and fixed thereto, it may be fixed at an appropriate position according to the work situation or carried by the operator.

FIG. 4 shows a second embodiment. The manual holding means (9) is attached in the vicinity of the distal end opening (16) on the injection tank side of the supply tube, and includes a suction disk or a magnet (18). By adopting such a structure, the tip of the supply tube can be fixed at an arbitrary position using the suction force of the suction disk or the magnet. That is, when injecting liquid from the supply tube (7) into the injection tank (8) (corresponding to the washing tub of the washing machine), the tip opening (16) of the supply tube is placed above the injection tank (8). After fixing and dropping the liquid and completing the injection of the liquid, the supply tube can be fixed and stored in a position where work is not adversely affected.
