Description

  TECHNICAL FIELD The present invention relates to a shower apparatus for cleaning a body using detergent mixed water in which liquid detergent and water or warm water is mixed, and in particular, a simple shower having a structure capable of providing liquid mixed water without using an electric device. Relates to the device.

  In a conventional shower device that jets hot water from the shower head, when the detergent is jetted from the shower device as a detergent mixed water previously mixed with hot water, a favorable cleaning effect on the body can be obtained and the detergent mixture jetted from the shower head Since it can be washed by a simple operation of applying water to the body, there is an advantage that time and labor can be saved by eliminating the trouble of washing. Therefore, it can be said that such a shower device is preferable for nursing care, for example.

  The invention disclosed in Japanese Patent Publication No. 200-107061 provides a detergent-mixed shower, in which an intermediate connector with a detergent tank is attached to a connecting portion between a shower hose and a water supply of a shower device, and the shower hose is attached to the shower hose. It is configured to be used as a detergent shower and a normal hot water or water shower by switching the valve of the detergent tank.

  According to the embodiment of the present invention, the shower apparatus described above connects the joint pipe to the hot water mixing tap, fixes the detergent tank in a required position, and connects the detergent hose to the nozzle inlet screwed into the joint pipe. Connect the shower hose to the connection port. The nozzle entrance is loosely inserted with a screw blade and a rotary blade for applying a rotational force to the blade blade. The screw blade has a function of preventing the water flow from flowing backward and a pumping action of sending out the detergent. The rotating blades are rotated by a tributary flowing through the joint pipe to give a rotational force to the screw blades. Furthermore, an opening / closing valve is provided in the detergent tank. With such a structure, the object of the detergent tank is to suck out the detergent from the detergent hose, mix it with hot water flowing through the joint pipe, and eject it from the shower hose to the outside.

  However, in the shower device described above, if the rotating blades loosely inserted inside the nozzle entrance do not rotate normally for some reason, part of the water flowing through the joint pipe enters the detergent tank, and the detergent is diluted or foamed. Failures such as a tank overflowing easily occur.

  For example, since the rotating blade is provided in a protruding state in the joint pipe, a part of the water flowing in the joint pipe enters the nozzle inlet side from the rear of the rotating blade and presses the screw blade to resist the rotation of the screw blade. In addition to the generation of force, the water flow is disturbed at the nozzle entrance and resistance to rotation of the rotating blades is also generated. In addition, when water pressure is uniformly applied to the entire rotating blade, the resistance force generated in the rotation of the rotating blade is further increased, and the operation of feeding the rotating blade becomes non-uniform. In this case, the detergent in the detergent tank cannot withstand the water pressure with the dropping force generated by providing the detergent tank at a position higher than the nozzle entrance and the force due to the uneven delivery, The possibility that a part of the water flowing through the joint pipe enters the detergent tank is increased.

  Further, according to the description and the disclosure of the drawings, the structure of the nozzle entrance is constituted by a rotary blade, a screw blade, a rotary shaft, and a frame that supports the rotary shaft. Therefore, when a part of the structure is damaged, the function of preventing the water flow of the screw blades from flowing backward or the pumping action of the detergent delivery cannot be obtained. As such, it can occur sufficiently because the structure of the structure is formed by connecting individual members and rotating under the pressure of water.

  If the detergent is surely sent out, it is necessary to provide a pump as a pressurizing device. Further, even when the rotating blade cannot be sufficiently rotated because the water pressure is low, it is necessary to provide a pump as a pressurizing device to pressurize the water flow. However, when a pump is provided as a pressurizing device, the structure of the entire shower device is complicated and the volume is increased, and the use of an electric device makes it uneasy in terms of safety.

The same diameter portion having the same length is formed, the inner diameter increases from a position close to the discharge port, reaches the discharge port, and the inner diameter of the same diameter portion is wider than the jet port of the nozzle portion.
With such a configuration, the object of providing a shampoo device capable of reliably mixing a liquid detergent and hot water with a simple structure without using an electrical device is achieved.
The structure and the embodiment will be described in detail below with reference to the drawings with specific examples.

  FIG. 1 is an explanatory view showing the structure of a shower device according to the present invention. According to the drawings, the shower device according to the present invention includes an aspirator 1, a suction pipe 2, an air adjustment valve 3, and a detergent storage tank 4.

  The aspirator 1 forms a supply port 10 at one end and a discharge port 11 at the other end. A water supply facility (not shown) that can supply water or hot water at a normal tap water pressure (about 0.1 to 0.2 Mpa) is connected to the supply port 10 through a distribution pipe. Specifically, for example, it is connected to a hot water supply port of a water heater or a tap of a water supply. A shower head is connected to the discharge port 11 through a water pipe.

  The suction tube 2 has a T-shape, one end is integrally connected to the aspirator 1, and the other end extends in parallel with the aspirator 1. The other is an air inflow portion 21 through which air flows, and the other Is a detergent inflow portion 22 into which liquid detergent flows. In addition, an air inlet 210 is formed at the end of the air inflow portion 21. The detergent inflow portion 22 gradually decreases in diameter along the axis, and forms a detergent inlet 220 at the end.

  The air inflow portion 21 of the suction pipe 2 is provided with an air adjustment valve 3 that adjusts the amount of air inflow at an appropriate position until reaching the air inlet 210 formed at the end.

  The detergent storage tank 4 is a container for storing a liquid detergent. The upper surface of the detergent storage tank 4 is an opening, and the detergent inlet 220 of the detergent inlet 22 is located in the detergent container tank 4. The bottom surface of the detergent storage tank 4 extends downward to form a pit portion 41. Liquid detergents include, for example, shampoo solution, rinse solution, body shampoo solution and the like.

  As shown in FIG. 2, the aspirator 1 is provided with a connecting hole 14 connected to the suction pipe 2 on the outer peripheral surface, and integrally connects one end of the suction pipe 2 described above. Further, the inner wall branches and extends from an appropriate position closer to the supply port 10 than the position where the connecting hole 14 is formed, and the nozzle portion 12 is formed by gradually reducing the diameter along the axial direction. A nozzle 120 is formed at the tip of the nozzle portion 12. The position of the jet outlet 120 is positioned downstream from the position where the connection hole 14 is formed, that is, closer to the discharge port 11.

  Further, a line passing through the center point of the end face forming the nozzle outlet 120 of the nozzle portion 12 extends to form a 45 ° inclined surface 121 from the position reaching the inner wall of the aspirator 1 to reduce the diameter, and further in the axial direction. The same diameter portion 13 having the same inner diameter by a predetermined length is formed by extending along the same length, and the inner diameter increases from a position close to the discharge port 11 to reach the discharge port 11. The inner diameter of the same diameter portion 13 is made wider than the nozzle 121 of the nozzle portion 12.

  The length of the same diameter part 13 shall be at least 60 mm or more. When the length of the same-diameter portion 13 is 60 mm, the nozzle 121 of the nozzle portion 12 is preferably 3 mm, and the inner diameter of the same-diameter portion 13 is 5 mm.

  The shower device according to the present invention is configured as described above. When this is used, when water or hot water flows in the aspirator 1 from a water supply device (not shown) connected to the aspirator 1 via a water pipe, the water pressure provided by the water supply device causes the nozzle portion 12 to The water pressure goes up once. However, air is sucked from the air inlet 210 of the suction pipe 2 and passes through the air inflow portion 21 so that the pressure is reduced when it is ejected from the outlet 120 of the nozzle portion 12 and flows into the same diameter portion 13. It flows into the aspirator 1 from the mouth 14. At the same time, the liquid detergent is sucked from the detergent inlet 220, passes through the detergent inflow portion 22, flows into the aspirator 1 from the connection port 14, and is mixed with the water ejected from the nozzle portion 12 of the aspirator 1 or hot water. It becomes mixed water, passes through the same-diameter portion 13 of the aspirator 1, is discharged from the discharge port 11, and is further ejected from a shower head (not shown) through the water pipe.

When air is sucked from the air inlet 210 and flows into the aspirator 1, an action of suppressing the amount of liquid detergent sucked occurs. That is, as the air intake amount increases, the liquid detergent intake amount decreases. Therefore, by operating the air regulating valve 3 interposed in the air inflow portion 21 to adjust the inflow amount of air, the inhalation amount of the liquid detergent can be adjusted.
41 Pit part 5 Detergent adjustment valve 6 Sphere When the air adjustment valve 3 is fully opened, the inflow of the liquid detergent stored in the detergent tank 4 into the aspirator 1 is blocked by the inflowing air and contains the liquid detergent. No water or warm water spews out of the shower head. Therefore, it can be selected whether water or hot water not containing liquid detergent is ejected from the shower head or detergent mixed water is ejected, and the liquid detergent stored in the detergent storage tank 4 is sucked and flows into the aspirator 1. The amount can be adjusted to prevent all inhalation in a short time, and detergent mixture water can be used on each part of the body.

  The detergent storage tank 4 may be fixed to a housing or a frame (both not shown) for storing the shower device, or may be provided detachably.

  The air flowing into the aspirator 1 from the air inlet 210 has an effect of adjusting the amount of liquid detergent sucked and being mixed and subdivided into the water flow. When the subdivided water flow passes through the same-diameter portion 13 of the aspirator 1, the water flow is depressurized. However, by moving the same-diameter portion 13 horizontally, the speed of water close to the center line is attenuated due to inertia. Pass without. As a result, even when water is supplied from a normal tap water supply facility, liquid detergent and air can be inhaled, and detergent-mixed water, water that does not contain detergent, or hot water is vigorously supplied from the shower head. Can be ejected.

  The aspirator in the prior art has a trumpet shape in which a portion corresponding to the same diameter portion 13 in the present invention gradually expands toward the discharge port. In such a shape, if it is located at a high position from the shower head, the water pressure discharged from the aspirator is not sufficient, and not only the water force ejected from the shower head is remarkably reduced, but also water is not ejected from the shower head. In some cases, backflow reduction may occur at the suction port. In order to prevent such a phenomenon, a pressurizing device such as a pump is provided to pressurize the water flowing in the aspirator from the water distribution pipe.

  However, the shower device in the present invention includes the aspirator 1 having a special structure including the same-diameter portion 13 as described above, and therefore does not require a pressurizing device such as a pump. Water without hot water and hot water can be ejected vigorously. Furthermore, since no electrical device is used, a favorable effect can be obtained with respect to safety.

  Further, in order to reliably stop the inflow of the liquid detergent stored in the detergent storage tank 4 and to more reliably adjust the inflow amount of the liquid detergent, as shown in FIG. A detergent amount adjusting valve 5 may be interposed.

  A second embodiment is disclosed in FIG. The second embodiment is configured in substantially the same manner as the first embodiment, but the structure of the detergent inflow portion 22 'of the suction pipe 2 is different.

  According to the drawing, the sphere 6 whose diameter is slightly narrower than the inner diameter of the detergent inflow portion 23 ′ is accommodated in the detergent inflow portion 22 ′. On the inner wall of the detergent inflow portion 22 ′, a rising restriction portion 221 is integrally formed at an appropriate position so as to prevent the movement of the sphere 6 with the liquid detergent and rising at an appropriate position.

  For the sphere 6, a material having a slightly higher specific gravity than the liquid detergent is selected. Alternatively, the inside is hollow and the specific gravity is adjusted to be slightly heavier than that of the liquid detergent.

  In the shower device having such a configuration, the sphere 6 is sucked and lifted together with the liquid detergent, and when the liquid detergent is sucked in a certain amount, the sphere 6 is restrained by the lift restricting portion 221 and stops rising, and the suction force of the aspirator 1 The state where the lift restricting portion 221 is stopped is maintained. In this state, the liquid detergent is prevented from flowing into the aspirator 1 by the sphere 6, and water not containing the detergent or hot water is ejected from the shower head.

  When the supply of water to the aspirator 1 is stopped and the suction force to the sphere 6 is released, the sphere 6 descends in the detergent inflow portion 22 ′ and reaches the detergent inlet 220 ′, and the liquid detergent becomes the sphere 6 and the detergent. It flows into the detergent inflow portion 22 ′ from the gap with the inner wall of the inflow portion 22 ′. In this state, since the specific gravity of the sphere 6 is heavier than that of the liquid detergent, it remains at the detergent inlet 220 '. The rising speed of the sphere 6 is adjusted by the air regulating valve 3. The liquid detergent stored in the detergent storage tub 4 can be divided into a plurality of times and used by repeating the suction, stopping and lowering operations of the sphere 6. That is, it is not necessary to replenish the liquid detergent storage tank 4 every time the shower device is used, which is convenient for use.

  The above is a preferred embodiment of the present invention, and does not limit the scope of implementation of the present invention. Accordingly, any modifications or changes that can be made by those skilled in the art, which are made in the spirit of the present invention and have an equivalent effect on the present invention, are all within the scope of the claims for registration of the utility model of the present invention. Shall belong.

  It is explanatory drawing which showed the structure of the shower apparatus by this invention (Example 1).   It is sectional drawing which showed the structure of the aspirator in this device.   It is explanatory drawing which showed other embodiment of the shower apparatus by this device.   It is explanatory drawing which showed the structure of the shower apparatus by another embodiment (Example 2).
