Description

   The present invention relates to a bath tub for hot bath therapy for treating an upper limb or a lower limb using hot water vortex or jet or air bubbles.

   When a conventional bathtub is used as a hot-bath therapy bathtub for treating the upper limb or lower limb with hot water vortex or jet or air bubbles, water moves outside the bathtub due to the movement of water after collision with the upper limb or lower limb. It may scatter and wet the surroundings or wet the user's clothes.

   Therefore, there is a conventional bathtub provided with a wave return so that hot water is less likely to splash outside (see, for example, Patent Document 1 and Patent Document 2). In the following, the wave return described in the conventional Patent Document 1 and Patent Document 2 will be described.

   The wave return described in Patent Document 1 is characterized in that an overflow port is provided in the bathtub so that the water level on the lower side of the wave return is determined together with the wave return.

   In the wave return described in Patent Document 2, an overflow port is installed in the bathtub together with the wave return, but it is not certain whether the position of the overflow port is installed on the lower side of the wave return. In addition, there exists the characteristic which gave the removal | desorption function to the said wave return part so that the dirt collected on the back side of the said wave return peculiar to the installed wave return shape may be easily cleaned.

   However, the wave return described in either Patent Document 1 or Patent Document 2 is a structure that projects the upper edge of a conventional bathtub inward, so that the performance is important for the purpose of bathing the upper limb or the lower limb in the bathtub. In order to secure a certain bathing opening area, the bathtub needs an extra size due to the wave return, which increases the manufacturing cost of the bathtub, and further increases the amount of water stored in the bathtub. Electricity costs to warm up will increase.

   Moreover, it is common that the dirt or dust adhering to the human body contains an oil and fat, and the dirt or dust containing the fat and oil has a property of floating on the water surface. Therefore, the dirt or dust present in the above-mentioned bathtub that immerses the human body often drifts on the surface of the water, which contributes to the problem of the dirt that accumulates on the back side of the above-described return described in Patent Document 2.

   Furthermore, in description of patent document 2, the overflow port installed in the above-mentioned bathtub inner side is installed in the arbitrary one points on the wall surface inside the said bathtub. In this case, around the overflow port, dirt or dust drifting on the surface of the water is collected due to the drained water, and the periphery of the wall inside the bathtub where the overflow port is installed is often a particularly dirty part. Will cause discomfort.

   In addition, due to the waves generated on the water surface, dirt or dust drifting on the water surface is collected on the inner wall surface of the bathtub and often adheres to the water surface line over the entire inner wall surface of the bathtub. The user feels uncomfortable.

   The problem to be solved is that when a conventional bathtub is used as a hot bath tub for treating the upper limb or lower limb with hot water whirlpools or jets or bubbles, the movement of water after collision with the upper limb or lower limb The water may splash outside the bathtub and wet the surroundings, or the user's clothes may be wetted. There is a point that an extra size is required due to wave return, and there is a point that the periphery of the overflow port installed inside the bathtub and the wall surface inside the bathtub become dirty.

The bath for hot bath therapy of the present invention is a bath for hot bath therapy for treating an upper limb or a lower limb using hot water vortex, jet, or bubbles, and a concave groove having a wave-return structure is provided on a horizontal surface of the upper wall of the bathtub. More than half of the line is installed so that the opening of the concave groove is inward of the bathtub, and is used as a drainage drain so that the upper edge of the bathtub does not protrude inward and is stored in the bathtub The most important feature is that a recessed groove drain outlet having a water level adjusting function for ensuring a constant distance between the water surface and the wave return structure is provided on the side surface or the lower surface of the recessed groove.

   The bathtub for hot bath therapy according to the present invention has a structure in which the upper edge of the bathtub is not protruded inward even if a wave return structure is installed. The ability to design without considering the extra size due to the wave-return structure allows the outer shape of the bathtub to be compact, making it possible to reduce manufacturing costs, further reducing the amount of water stored in the bathtub, and saving the electricity bill for warming the water. There is an advantage that you can.

   In addition, by installing the recessed groove drainage port in the recessed groove, the opening height of the wall surface made by the recessed groove itself is the distance between the water surface stored in the bathtub and the wave return structure, By adjusting the distance, there is an advantage that the effect of wave return by the wave return structure can be sufficiently extracted.

   In addition, by installing the drain in the concave groove in the concave groove described above, the entire concave groove has a function as a drainage drain, so that the dirt on the inner wall surface of the bathtub does not remain and dirt or dust drifts on the water surface. Is collected in the concave groove that is difficult to see during normal use. For this reason, at the time of treatment, dirt on the wall surface inside the bathtub does not enter the user's field of view and can be used comfortably.

   In addition, due to the waves generated in the above-mentioned bathtub during treatment, dirt or dust is attracted to the above-mentioned recessed groove drain and discharged from the above-mentioned recessed groove outlet to the outside of the bath for bathing. There is an advantage of reducing the labor to do.

   While installing a wave return structure in the bathtub, a sufficiently large bathing opening area is taken to make it difficult for the user to visually recognize the dirt in the bathtub, and when cleaning the bathtub, the cleaning effort is reduced. This was achieved by installing a concave groove with a drainage function.

   Hereinafter, embodiments will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a bathtub for warm bath therapy using a swirl for upper limbs according to one embodiment of the present invention, and FIG. 2 is a top view thereof. FIG. 3 is a cross-sectional view of the concave groove 21 according to this embodiment.

   Since the main body of the present invention is in the structure of the bathtub 12, the description of the control unit 30 and the mechanism unit 19 is only schematic.

   1 and 2, a cover 18 surrounds a bathtub 12 that is large enough to treat a desired upper limb, and a mechanism necessary for operating this device around the bathtub 12 inside the cover 18. 19, The control part 30, the left hose 33, the right hose 34, the recessed groove drain hose 35, and the lower drain hose 37 are installed.

   Further, a left nozzle 14, a right nozzle 15, a heater 16, a lower drainage port 17, a recessed groove 21, and a water level sensor 31 are installed in the bathtub 12.

   The mechanism unit 19 includes a circulation pump 32, and the left nozzle 14 in the bathtub 12 is connected to the circulation pump 32 by the left hose 33, and the right nozzle 15 in the bathtub 12 is connected to the circulation pump 32 by the right hose 34. To do.

   The lower drain 17 is connected to the lower drain trap 38 and the circulation pump 32 by a lower drain hose 37. A drain plug 39 is installed between the lower drain trap 38 and the lower drain hose 37, and is closed for supplying water to the circulation pump 32 during normal use.

   Further, a recessed groove drain port 22 is installed in the recessed groove 21 in the bathtub 12, and the recessed groove drain port 22 is connected to a recessed groove drain trap by a recessed groove drain hose 35. Since this trap does not need to be closed, this portion is always open.

   During use, water is stored inside the bathtub 12 and used, and the water level is constantly monitored by the water level sensor 31.

   When the hot water temperature setting is input through the operation panel 11, the heater 16 is controlled through the control unit 30 according to the input control signal, and the water in the bathtub 12 is warmed to the temperature setting input by the heater 16 and becomes hot water. Become.

   Before starting the treatment, the user enters the upper limb to be treated from the opening on the upper surface of the bathtub 12 and, after completing the entry, operates the operation panel 11 to start the treatment. The unit 19 is controlled, hot water is supplied to the mechanism unit 19 from the lower drain port 17 by the lower drain hose 37, and the vortex generated from the mechanism unit 19 passes through the left hose 33 and from the left nozzle 14 and through the right hose 34 to the right. It is discharged from the nozzle 15 into the hot water in the bathtub 12.

   The strength of the eddy current is adjusted to such a level that a large undulation is generated on the water surface even when treatment is started in a state where the upper limb is not filled.

   The treatment is stopped by operating the operation panel 11 and inputting the treatment stop, or using a timer mounted on the operation panel 11.

   This example is just an example, and only one of the left nozzle 14 and the right nozzle 15 may be installed. Moreover, when treating using air bubbles, since a bubble generator is separately installed in the bathtub 12, the nozzle becomes unnecessary.

   In the case of a conventional bathtub, whirlpools discharged from the left nozzle 14 and the right nozzle 15 hit the user's upper limb during treatment, and the water after the collision scatters water to the outside of the bathtub. May get wet or wet user's clothes.

   For this reason, the concave groove 21 having both the wave return structure 23 and the concave groove drain port 22 is installed on the upper wall surface of the bathtub 12.

   FIG. 3 is a cross-sectional view showing the structure of the concave groove 21 according to the first embodiment of the present invention.

   The concave groove 21 is installed on the horizontal line of the upper wall surface inside the bathtub 12 so that the opening of the concave groove 21 is inward, and the installation range is a control unit installed in the cover 18 in the embodiment of FIG. 39, for the convenience of the layout of the mechanism 19 and hoses, it is installed on about half of the wall surface.

   In addition, this example is an example and the range which installs the recessed groove | channel 21 can also be partially installed in the perimeter of the wall surface inside the bathtub 12, or a required location.

   The upper surface formed by the groove of the concave groove 21 becomes a wave-return structure 23, and the concave groove 21 is installed on the lower surface, so that the entire concave groove 21 has a function as a large drainage drain. be able to.

   The water surface inside the bathtub 12 is located immediately below the lower surface of the concave groove 21 immediately before use, and is monitored by the water level sensor 31.

 By entering the upper limb, the water level increases, hot water flows into the concave groove 21, passes through the concave in-house drain port 22, passes through the concave in-groove drain hose 35, and is discharged to the outside by the concave in-groove drain port trap 36.

   Therefore, the water surface of the bathtub 12 is not located above the lower surface of the concave groove 21 except for the height of waves of hot water flowing into the concave groove 21.

   The wave of hot water flowing into the concave groove 21 hits the wave return structure 23 on the upper surface along the lower surface of the concave groove 21 and is returned to the lower surface of the concave groove 21 or the bathtub 12.

   If the distance between the wave return structure 23 on the upper surface of the concave groove 21 and the lower surface of the concave groove 21 is set to an optimum distance in accordance with the height of the wave, the distance between the inflowing wave and the wave return structure 23 is set. Is ensured to be constant, and the effect of wave return can be sufficiently brought out.

   Further, this structure and effect can eliminate the inward protrusion peculiar to the wave return, the entire opening surface of the bathtub 12 can be effectively used as a bathing opening area, and the extra size of the bathtub 12 by the wave return structure 23 Since the design can be made without taking into account the size, the outer shape of the bathtub 12 can be made compact, the manufacturing cost can be reduced, the amount of water stored in the bathtub can be saved, and the electricity bill for warming the water can also be saved. .

   Since the entire opening of the concave groove 21 has a function as a drainage drain, dirt or dust drifting on the water surface does not stay on the inner wall surface of the bathtub 12 but flows into the concave groove 21 on the wave and is collected by the concave groove 21. Is done.

   During normal use, the user has almost no line of sight from the upper surface, and therefore dirt or dust accumulated in the concave groove 21 does not easily enter the user's field of view, so that the user can use it comfortably. .

   Further, since dirt or dust is attracted to the recessed groove drain 22 due to the waves generated in the bathtub 12 at the time of treatment, it is discharged from the recessed groove drain 22 to the outside of the hot bath therapy bathtub and cleaned. There is also an advantage of reducing labor.

   In addition, by installing a filter that removes dirt or dust at the drain groove 22 in the concave groove, the dirt or dust to be discharged can be collected in advance.

   When the water in the bathtub 12 is periodically drained and the inside of the bathtub 12 is cleaned, the drain plug 39 is opened so that the lower drainage from the lower drain 17 on the bottom of the bathtub 12 through the lower drain hose 37 is performed. Water is discharged from the mouth trap 38 to the outside for cleaning.

   Moreover, the upper part of the concave groove constitutes a support base 13, and the support base 13 can be easily treated by the user by leaning on the user during the treatment.

   The support base 13 can be freely formed because it is irrelevant to the wave return structure 23 of the concave groove 21. However, when the desorption mechanism for use of the support base 13 as described in Patent Document 2 introduced above is installed, it is considerably If the mechanism is not capable of withstanding the load, the user will excessively lean on the support table 13 during treatment, or when the user attempts to stand up, the support table 13 will be used as a handrail and a load higher than expected will be applied. The support base 13 is unexpectedly removed, and there is a risk that the user will be injured.

   For this reason, the support base 13 has a structure that cannot be detached during normal use.

   The wave return structure 23 of the concave groove 21 and the support base 13 do not need to be separated, and the bottom of the support base 13 can be used as the roof of the concave groove 21 structure in order to reduce manufacturing costs.

   FIG. 4 is a cross-sectional view showing the structure of the concave groove 21 according to one embodiment of the present invention.

   In order to prevent the backflow of dirt or dust and increase the collection effect, the lower surface of the concave groove 21 is inclined toward the concave construction drainage port 22 side so that the water flows more into the drainage port.

   FIG. 5 is a sectional view showing the structure of the concave groove 21 according to one embodiment of the present invention.

 In order to prevent the backflow of dirt or dust and increase the collection effect, a barrier 24 that is a slight convex portion is provided between the concave groove 21 and the bathtub 12.

   FIG. 6 is a cross-sectional view showing the structure of the concave groove 21 according to one embodiment of the present invention.

 Even when the hot water is reduced, the concave groove drain port 22 is installed on the side surface of the concave groove 21 so that the wave return and dirt are difficult to visually recognize, and the water surface of the bathtub 12 is above the lower surface of the concave groove 21. Is set to be.

   FIG. 7 is a cross-sectional view showing the structure of the concave groove 21 according to one embodiment of the present invention.

   The bottom surface of the concave groove 21 is inclined to the bathtub 12 side, and the concave groove drain port 22 is installed on the inclined surface of the bottom surface of the concave groove 21 so that the effect of wave return can be obtained.

   FIG. 8 is a top view of Example 6 of the bath for warm bath therapy using the eddy current for the upper limb according to one embodiment of the present invention, and the shape from the upper surface of the concave groove 21 is represented by a dotted line.

   Here, the depth of the recessed groove 21 is not only equal to the entire circumference, but also the depth of the recessed groove 21 is made deeper near the recessed groove outlet 22, and the waves approach the recessed groove outlet 22. It is also possible to make it easy to gather.

   In addition, this example is an example, and although the position where the concave groove 21 is installed is located in two places in FIG. 8, only one of them can be installed.

   In addition, although Example 1 thru | or 6 was represented for upper limbs, this invention can be implemented similarly also for lower limbs.
