Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic footbath.

[0002]

2. Description of the Related Art As a conventional means for washing the feet, there are known ones that use bubbles ejected into the cleaning liquid, ones that give vibrations to the cleaning liquid, and ones that contact a brush.

[0003]

However, these means have a drawback that the cleaning force is weak because the collision force and the frictional force of the cleaning liquid on the foot are small, and in particular, the narrow gap between the fingers cannot be effectively cleaned. Was there.

[0004]

In order to solve the above-mentioned problems, an automatic foot-washing machine according to claim 1 of the present invention has a capacity capable of putting a user's foot therein, and has a cleaning solution and a ceramic ball inside. And a circulation tank for circulating the cleaning liquid in the slurry in the cleaning tank to inject it from a slurry injection port provided in the cleaning tank. The height of the ceramic ball layer with respect to the plane area of the slurry housed inside is 10 to 70 mm, and the total weight of the ceramic balls is 3 mm.
It is characterized by being ~ 7kg. According to a second aspect of the invention, in the automatic foot-washing device according to the first aspect, the ceramic balls carry an antibacterial agent. Furthermore, the invention of claim 3 is characterized in that, in the automatic foot wash device of claim 1 or 2, an antibacterial agent is carried in the cleaning tank.

[0005]

According to the first aspect of the present invention, the foot is washed by injecting the washing liquid in the slurry in which the washing liquid and the ceramic ball are mixed from the jet port. The ceramic ball hits the foot and collides with the foot, The adhered dirt is effectively washed away by the cleaning liquid. Further, the height of the ceramic ball layer of the slurry contained in the cleaning tank should be 10 to 7
By setting the thickness to 0 mm and the total weight of the ceramic balls to 3 to 7 kg, the feet can be sufficiently embedded in the slurry without the ceramic balls popping out. According to the second aspect of the invention, the antibacterial agent carried on the ceramic balls can suppress the growth of bacteria and microorganisms in the ceramic balls for a long period of time. Further claim 3
In the invention, the antibacterial agent carried in the cleaning tank can suppress the growth of bacteria and microorganisms in the cleaning tank for a long period of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An automatic foot washing machine according to an embodiment of the present invention will now be described with reference to the drawings. The automatic foot washing machine is shown in perspective view in FIG. 1 and internal structure in FIG. Bowl 1
Is suitable for installation in hospitals, hotels, etc., and has a resin main body 3 forming the cleaning tank 2. Cleaning tank 2
At the front part of the pump P, an operating portion 6 provided with a starting switch 4 and an adjusting switch 5 for the pump P is integrally provided.
Is housed inside the operation unit 6.

The cleaning tank 2 contains a slurry S containing a mixture of a cleaning liquid (water) W and ceramic balls B to B (see FIG. 3). Each ceramic ball B has a grain size of 0.
It is composed of alumina balls or zirconia balls of 5 to 5.0 mm, and carries an antibacterial agent. As the antibacterial agent, for example, metal ions such as silver, copper, zinc, mercury, lead, tin, bismuth, cadmium or thallium and their compounds or stabilized chlorine, hypochlorite, chloramine,
Examples thereof include halogen compounds such as ethylene iodide, alcohols, phenols, ethers, and guanidines. In terms of high safety to humans and strong antibacterial activity, the above-mentioned silver, copper, zinc and tin ions or The compound is suitable. The ceramic balls B are formed by dispersing these antibacterial agents with a dispersant, and the antibacterial agents disable the energy metabolism of the cells to be bacteria,
The growth of microorganisms can be suppressed for a long period of time, and the surface and the like of the ceramic balls B can be maintained in a sterile state.

Further, in this embodiment, the main body 3 including the cleaning tank 2
Is also molded from a resin carrying an antibacterial agent as described above.

As shown in FIG. 3, a support plate 2A forming an insole is installed at the bottom of the cleaning tank 2, and the support plate 2A has a plurality of slurry injection ports 7 to 7 at equal intervals. Is provided. At the bottom of the cleaning tank 2, a slurry injection port 7-
A circulation pipe 9 including the injection pipe portions 8 to 8 connected to 7 is arranged. The circulation pipe 9 is connected to the pump P,
Further, it is connected to a plurality of slurry suction ports (not shown) provided on the upper part of the inner wall of the side portion of the cleaning tank 2. Therefore, when the pump P is started, the slurry is sucked from the slurry suction port and is jetted upward from the slurry jet ports 7 to 7. The circulation pipe 9 and the pump P constitute a circulation injection device 10. The slurry suction port is provided with an appropriate screen for preventing the ceramic balls B to B from flowing into the circulation pipe 9.
Only the cleaning liquid W is jetted from the slurry jet ports 7 to 7.

Here, it is preferable that the ceramic balls B to B filled in the cleaning tank 2 have a cleaning effect effectively on the entire foot and are prevented from jumping out by the above injection. The height H of the filled ceramic ball layer with respect to the plane area is 10 to 70 mm (for example,
If the bottom area of the washing tank 2 is 40 x 35 cm, the height is 3
5 cm is preferable), and the total weight of the ceramic balls B to B is set to 3 to 7 kg.

In this embodiment, as shown in FIG. 3, a user immerses his / her foot in the slurry S of the cleaning tank 2 and places it on the support plate 2A, and in this state, the start switch of the operation portion 6 of the main body 3 is activated. Four
When the switch is turned on, the pump P is activated and the cleaning liquid W of the slurry S is jetted upward from the slurry jet ports 7 to 7, and the ceramic balls BB collide with the feet together with the jet flow, so that the dirt attached to the feet is effective. Washed away. here,
The jet also reaches the gap between the toes, and dirt on this part can be effectively removed. Further, the ceramic balls B to B collide with the foot, so that a massage effect can be obtained and fatigue of the foot can be removed.

Further, the flow rate of the pump P can be changed by adjusting the adjusting switch 5 of the operating portion 6 to adjust the strength of the jet flow.

Further, in this embodiment, the ceramic ball B is used.
Since the antibacterial agent is carried on B to B and the antibacterial agent is carried on the cleaning tank 2 as well, the growth of bacteria and microorganisms can be suppressed for a long period of time, and the surfaces thereof can be kept aseptic. Excellent hygiene effect.

[0014]

According to the first aspect of the invention, the dirt adhering to the foot is effectively washed away by the collision of the ceramic balls, so that the cleaning effect is excellent. Further, since the feet can be sufficiently buried in the slurry without the ceramic balls jumping out of the cleaning tank, there is an advantage that cleaning efficiency is improved. In the inventions of claims 2 and 3, the antibacterial agent carried on the ceramic balls and the cleaning tank respectively can suppress the growth of bacteria and microorganisms for a long period of time, so that an excellent effect on hygiene is brought about. .
