Description

  The present invention relates to a lower limb water discharging apparatus that discharges water toward a lower limb stored in a container.

  2. Description of the Related Art In recent years, what is called a lower limb water discharging device or a foot massage device including a container for storing a lower limb and a nozzle for discharging water toward the lower limb stored in the container has gained popularity. This is because it has a massage effect in addition to the effects such as removing foot socks by simply taking off socks, etc., and promoting blood circulation by using warm water. This is due to the expectation of recovery of the skin, removal of swelling of the feet, and a beauty effect on the skin.

  Since this lower limb water discharge device uses hot water, it is often installed in the living room or bedroom so that it can be more relaxed while being installed around the water, such as in a bathroom or washroom.

  However, when it is used in a space that does not have such a water supply / drainage facility, it is necessary to go to the place where the water supply / drainage facility is located, or to throw it away after use. When water is supplied, it is still possible to draw water into a washbasin etc. and transport it to the lower limb water discharging device, but when draining, it is necessary to carry heavy equipment to the bathroom and discard it. There are some with casters, but it is troublesome to run around in a small house with furniture.

  Therefore, a foot massager has been proposed in which a drainage tank is detachably installed outside the container for storing the foot, and the water in the container is guided to the drainage tank via the drainage hose by the power of the pump (for example, patent) Reference 1).

  However, in this configuration, since the discharge stops when air passes through the pump, water remains in the drain hose or the pump. Moreover, this drainage tank is not used for water supply.

  Further, the water tank into which the user's foot is inserted is separated from the main body casing having a drive unit that rotationally drives a pump unit disposed outside the water tank, and the water tank is attached to the main body casing. On the other hand, an automatic foot washing apparatus that is detachable is known (see, for example, Patent Document 2).

However, this water tank, when cleaning the inner surface of the water tank, is separated from the main body casing and carried to an appropriate washing place such as a bathroom, and is removable from the main body casing for cleaning, At the time of drainage, the entire apparatus is erected vertically. At this time, the drainage port is located on the lower side, and in this state, the on-off valve is opened to discharge the water in the water tank to the outside through the drain pipe 28. That is, at the time of drainage, it is necessary to carry the entire apparatus to an appropriate washing place such as a bathroom.

  Preferably, the water supply / drainage tank is mounted at a position that is higher than the water discharge means during water supply and lower than the lower limb storage space by rotating the main body by approximately 90 ° during water discharge. It is desirable that

  According to the lower limb water discharging apparatus according to the present invention, it is possible to supply and drain hot water without moving the apparatus main body.

  An embodiment of a lower limb water discharging apparatus according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an overall outline of a lower limb water discharging device 1 according to this embodiment by cutting it into a right foot side and a left foot side.

  As shown in the figure, the lower limb water discharging device 1 according to the present embodiment has a lower limb storage space LS in which the upper part is opened and the lower limb storage space LS is stored in the main body 2 having a substantially rectangular parallelepiped shape. .

  A mesh-like plate (not shown) is placed on the bottom surface 3 that defines the lower end of the lower limb storage space LS to provide a footrest for supporting the user's feet. A water storage pit 4 is formed for collecting hot water discharged toward the feet.

  In the lower limb storage space LS, an upper nozzle 5, a lower nozzle 6, and a rear nozzle 7 (hereinafter, collectively referred to as “water discharge nozzle”) are disposed as water discharge means.

  The upper nozzle 5 is located on the shaft 5a laid between the left and right side surfaces of the main body 2 in the vicinity of the upper corner in front of the lower limb storage space LS (on the side where the user's toes are located, left side in FIG. 1). A plurality of water outlets are provided. The shaft 5a circulates in the interior thereof, and is rotated by a motor 8 installed on the side surface of the main body 2. The shaft 5a discharges water only while the water discharge port is directed from the user's toe to the vicinity of the heel.

  In the water storage pit 4, the lower nozzle 6 is formed by providing a pair of left and right water outlets on a shaft 6 a that is installed between the left and right side surfaces of the main body 2. Inside the shaft 6a, hot water circulates and is driven by a motor 9 installed on the side surface of the main body 2. The water discharge port 6b discharges water while reciprocating from the toe of the user's sole to the vicinity of the heel.

  The rear nozzle 7 is provided on the rising portion 10 that separates the rear side of the main body 2 and the left and right feet, and discharges water from the left and right of the user's lower leg.

  A water supply / drainage tank 30 that is detachably attached to the main body 2 at the outer top of the front of the main body 2 supplies discharged hot water to the main body 2 and collects and drains used hot water. To do. A water amount observation window 31 is provided on the side surface of the water supply / drainage tank 30. The water amount observation window 32 provided on the upper surface is a case where the lower limb water discharge device 1 is rotated by 90 °.

  Valves 11 and 12 are provided on both side surfaces outside the main body 2 to operate whether hot water in the water supply / drainage tank 30 is taken into the main body or not drained.

  A caster 13 is provided at the front lower part outside the main body 2, and a stopper rubber foot provided in the vicinity of the caster 13 by pulling up the handle 14 provided at the rear middle stage outside the main body 2 (see FIG. 8). Since it will leave | separate from a floor and only a caster will earth | ground, the movement of the lower limb water discharging apparatus 1 can be performed comparatively easily. The handle 14 is also a clue when the lower limb water discharging device 1 is lifted to rotate (described later).

  The hot water supplied from the water supply / drainage tank 30 is circulated in the main body 2 by the circulation pump 15 installed in the lowest part of the main body 2. The outline of this circulation will be described with reference to FIG.

  When the water supply from the water supply / drainage tank 30 to the circulation pump 15 via the pump inflow pipe 16 and to the water storage pit 4 via the pit inflow pipe 17 is completed and the water discharge start switch is turned on, the circulation pump 15 flows out. Hot water is pumped to the pipe 18.

  Since the water is directly supplied to the pump here, no air clogging occurs immediately after the start of operation, so that the initial stable operation is guaranteed.

  The outflow pipe 18 branches into an upper outflow pipe 19 connected to the upper nozzle 5, a lower outflow pipe 20 connected to the lower nozzle 6, and a rear outflow pipe 21 connected to the rear nozzle 7. It is sent to the nozzle and discharged into the lower limb storage space LS.

  The discharged hot water is collected in the water storage pit 4, returned to the circulation pump 15 through the return pipe 22, and pumped again from the circulation pump 15, and this is repeated to continue water discharge.

  As shown in FIG. 3, the water supply / drainage tank 30 has an upper portion formed in two steps, and the water supply / drainage port closed by the cap 33 is provided in the lower step. The cap 33 is provided with a vent hole.

  A clue 34 is recessed at both corners of the side surface of the water supply / drainage tank 30 not facing the main body 2, and a guide recess 35 is recessed at the center of the lower portion of the side surface in contact with the main body 2. As shown in FIG. 4, the guide recess 35 engages with a positioning guide 23 projecting from the main body 2 to facilitate the positioning of the both, and also serves to make them difficult to come off.

  A magnet 36 is fixed on the lower surface of the water supply / drainage tank 30, and a magnet 24 is also fixed on the main body 2 at a position facing the magnet 36. Due to the attractive force of these magnets 24 and 36, the water supply / drainage tank 30 and the main body 2 are more easily attached with less difficulty of detachment. This is important from the standpoint of water stoppage and the fact that the main body 2 is turned 90 degrees. One of the magnets 24 and 36 may be a metal having magnetism.

  As shown in FIG. 5, the water supply / drainage tank 30 includes a water inlet / outlet 37 closed by the cap 33, and another inlet / outlet 38 just below the water inlet / outlet 37. A round bar 39 is suspended from the doorway 37, and a piston 40 is externally fitted to the round bar 39. On the other hand, the cylinder 25 is protruded at a position facing the doorway 38 of the main body 2. The cylinder 25 is water-stopped by an O-ring 26 on the outer periphery.

  As shown in FIG. 5A, the piston 40 is urged by a spring 41, and the bottom surface 40 a is pressed against the water inlet / outlet 38 to close the water inlet / outlet 38. Therefore, even if the water supply / drainage tank 30 is separated from the main body 2, hot water contained therein does not leak from the water inlet / outlet 38.

  However, when the water supply / drainage tank 30 is connected to the main body 2, the cylinder 25 is inserted into the water inlet / outlet 38 to push up the piston 38, and when the three bottom surfaces 40 a are separated from the water inlet / outlet 38, Flow into. At this time, the gap between the water inlet / outlet port 38 and the outside is stopped by the O-ring 26 and does not leak to the outside.

  Then, the procedure of the water supply / drainage by this water supply / drainage tank 30 is demonstrated. First, at the time of water supply, the water supply / drainage tank 30 is removed from the main body 2, water is supplied in a wash basin or bathroom, and this is attached to the main body 2. At this time, the valves 11 and 12 connected to the pump 15 and the water storage pit 4 are closed and opened after the water supply / drainage tank 30 is mounted. Thereby, the hot water in the water supply / drainage tank 30 flows into the main body 2 as shown in FIG. 6A, and finally the hot water in the water supply / drainage tank 30 is shown in FIG. 6B. , All move into the water storage pit 4 and the circulation pump 15. Thus, hot water is drawn into the circulation pump 15 independently, so that the circulation pump 15 is prevented from idling with air.

  In order to prevent the valves 11 and 12 from being forgotten to be opened or closed, it is desirable to use an electric valve and be sure to be closed when the circulation pump 15 is operated.

  When the water supply is completed, the valves 11 and 12 are closed before the water discharge is started. This is because if the circulation pump 15 is operated in an open state, air is drawn from the water supply / drainage tank 30 and idling occurs.

  When draining, the circulation pump 15 is stopped and the water discharge operation is stopped, and then the valves 11 and 12 are opened as shown in FIG. Then, holding the handle 14 of the main body 2, the lower limb water discharging device 1 is rotated by 90 ° as shown in FIG. At this time, even a small force can be caused by the lever principle using the caster 13 as a fulcrum. Further, as shown in FIG. 8, a plurality of rubber stopper rubber feet 27 are attached in the vicinity of the caster. When this occurs to some extent, this functions as a stopper, so that the caster 13 does not slip. The stopper rubber feet 27 also serve as a guard that prevents the main body from directly contacting the floor.

  Then, the hot water in the water storage pit 4 naturally falls into the water supply / drainage tank 30. Further, since the circulation pump 15 is also arranged at a position higher than the level L2 of the water inlet / outlet 38 shown in the figure, the hot water in the circulation pump 15 naturally falls into the water supply / drainage tank 30 as well.

  Further, since the capacity of the water supply / drainage tank 30 of level 2 or less is made larger than the capacity of the level L1 of the water inlet / outlet 38 before the lower limb water discharge device 1 is raised, hot water does not remain in the main body 2 due to insufficient capacity.

  At this time, the vent provided in the cap 33 serves to remove air. Since it is provided on the cap 33, it will not be submerged from the vent.

  The hot water collected in this way can be separated from the main body 2 from the main body 2 and taken to a washbasin or a bathroom to be drained. It can be drained.

  Moreover, since it drains by natural fall, a drainage pump etc. become unnecessary and can reduce a manufacturing cost and an operating cost.

  The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, but these embodiments are also included in the scope of the present invention.
