  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 is a perspective view with the cover 30 of the cleaning device removed in the first embodiment of the present invention, FIG. 2 is a front view of the cleaning device, FIG. 3 is a side view showing a use state, and FIG. ), (B) are a sectional view of an example of a spray nozzle and a front view of a swivel tip. FIG. 5 is an explanatory diagram of an operation unit of the cleaning device, and FIG. 6 is a block diagram illustrating a flow path of the cleaning device.

  As shown in the figure, this cleaning device has a small footprint, so it is not necessary to create a shower room alone, and it must be installed in an existing bathroom (not shown) or shower room (not shown). Can do. This cleaning device is composed of a cleaning device main body 31, a pair of left and right arm portions 32, and a chair portion 33 as seating means. The arm portion 32 can be stopped at an appropriate position by a rotatable means 34 provided in the cleaning apparatus main body 31. A total of 10 spray nozzles 35 are arranged on the arm portion 32, 5 on each of the left and right, and 2 in the cleaning device main body 31. In this embodiment, the number of spray nozzles 35 is twelve, but the number is not limited as long as it is an arrangement that wraps around the user's body. Further, in the present embodiment, the chair portion 33 is provided so that the user can sit comfortably and take a shower. However, a separate chair may be used or no chair may be used.

  As shown in FIG. 3, the user 36 sits on the chair portion 33 with the cover 30 and the cleaning device main body 31 in the back. The arm portion 32 can be rotated and moved to an appropriate position, and all the 12 spray nozzles 35 can be directed toward the user 36 and the sprayed hot water can be disposed so as to wrap around the user's 36 body. .

  As shown in FIG. 2, the hot water supply device 37 is connected to a water supply pipe 38 and a hot water supply pipe 39. The hot water supply device 37 has a built-in mixing valve 40 as a means for mixing hot water and water, and can supply hot water at a set temperature. A thermistor 41 is attached near the outlet of the mixing valve 40 to detect the mixed hot water temperature. The hot water supply device 37 is connected to the pressurizing device 43 by a pipe line through a water stop electromagnetic valve 42 that controls the flow and stop of hot water.

  The pressurizing device 43 needs to be able to ensure a discharge pressure of 0.2 MPa or more even when a necessary amount of gas is mixed in hot water, and it is usually necessary to select a pump having a high head. Moreover, the flow rate of the hot water can be changed by controlling the rotation speed. The method for controlling the flow rate of hot water is the same as the method for changing the passage resistance in the pipe other than the rotational speed control.

  The gas mixing unit 44 is disposed between the water stop electromagnetic valve 42 and the pressurizing device 43, and controls the inflow amount of gas by the gas control valve 45. By providing the governor mechanism 46 in the gas control valve 45 and keeping the amount of gas flowing in constant, vibration of the pressurizing device 43 can be suppressed. If the gas inlet 47 is opened to the atmosphere, air is taken in. In the present embodiment, air is mixed in hot water, but oxygen, carbon dioxide or other gas supply device (not shown) is connected to the gas inlet 47 and the gas alone or air or other gas is connected. A gas mixed with a gas can also be used.

The detergent supply device 48 includes a detergent tank 49 and a detergent adjustment valve 50, and the detergent tank 49 is connected to the gas mixing unit 44 so that the stored detergent is mixed into the gas mixing unit 44 via the detergent adjustment valve 50. . The cover 30 is provided with a detergent inlet 51 shown in FIG. 1 so that the user 36 can supply a necessary amount of detergent to the detergent tank 49.

When hot water containing gas is pressurized by the pressurizing device 43, the gas is compressed while being mixed with hot water, so that the gas is dissolved in the hot water. In the pressurized liquid, the saturated dissolution amount is larger than the atmospheric pressure, so that the gas is easily dissolved. Therefore, the gas of the maximum saturation is dissolved in an amount of inflow gas to the hot water pressurized by setting the hot water quantity of more than the saturated dissolution amount of pressurized. At this time, the gas that has not been dissolved flows out in a bubble state with hot water.

  In FIG. 2, there is a dissolution tank 52 disposed by a conduit on the discharge side of the pressurizing device 43, and a degassing unit 53 is disposed. The dissolution tank 52 has a cross-sectional area larger than the cross-sectional area of the pipe line. For this reason, when hot water enters the dissolution tank 52, the flow rate becomes slow. At this time, the gas not dissolved in the hot water in the pipe is separated from the hot water. Moreover, since a cross-sectional area will spread if it enters into the dissolution tank 52, the pressurized hot water is once pressure-reduced. A part of the gas that has been dissolved in the hot water in a saturated state is also deposited by the amount of the reduced pressure and the amount of saturation, and bubbles up and floats to become a gas separated from the hot water. These gases are separated from the hot water in the dissolution tank 52, and the upper part is gas and the lower part is hot water. At this time, in the dissolution tank 52, it is still in a pressurized state, and the gas dissolved in the hot water becomes uniform. In order to prevent the gas collected at the upper part from being mixed with the hot water flowing downstream, the pipe structure flows downstream from the bottom of the dissolution tank 52.

  The degassing unit 53 is arranged at the upper part of the dissolution tank 52 and has a structure for discharging the gas accumulated at the upper part from the outlet 54 so as not to be mixed with hot water. Although the exhausted gas shows a structure that is released to the atmosphere, although not shown, it is returned to the gas mixing unit 44 again, mixed with new (fresh) gas, and mixed with hot water from the gas mixing unit 44. It is also possible to do.

1 and 2, in this embodiment, a flow rate detection device 55 and a switching valve 56 are arranged in a pipe line between the dissolution tank 52 and the spray nozzle 35. The flow rate detection device 55 is a device that measures the amount of hot water flowing in the pipe and outputs a signal. Switching valve 56 is connected to the one spray nozzle 35 for switching the tube passage valve and the other is connected to the hand shower 58 in the shower hose 57 you freely curvilinear. The hand shower 58 is not limited to the one that discharges a simple shower that is usually attached to a faucet or the like, or a structure that also has a sprayed shower. In addition, the switching valve 56 may have a structure for switching between hot and cold water, and a plurality of valve bodies (not shown) may be combined.

  The spray nozzle 35 is connected to the header 59 on the downstream side of the switching valve 56, branches in three directions to the hoses 60a, 60b, 60c, and the spray nozzle 35 attached to the left and right arms 32, and a cleaning device. It is connected to a spray nozzle 35 attached to the main body 31.

  Further, a pipe line is branched on the upstream side of the switching valve 56, a drain valve 61 composed of an electromagnetic valve is provided, and connected to the drain port 63 through the drain pipe 62. When the drain valve 61 is stopped, hot water flows through the switching valve 56 and is discharged from the spray nozzle 35 or the hand shower 58. When the drain valve 61 is operating, it is set so that all hot water flows from the drain valve 61 and is discharged from the drain port 63 to the outside of the cleaning device. When the hot water temperature is too hot or too cold than the temperature set by the user 36, the drain valve 61 discharges the water from the drain 63 through the drain pipe 62 to the outside of the cleaning device. Further, when the detergent staying in the pipe is discharged early, the drain valve 61 is operated to purify the pipe to the switching valve 56, and the portion downstream from the switching valve 56 is discharged from the spray nozzle 35 or the hand shower 58. If the water is purified, the inside of the pipe can be cleaned faster than when the water is simply discharged from the spray nozzle 35 or the hand shower 58 and cleaned, and it is possible to prevent the spray nozzle 35 or the hand shower 58 from spraying a lot of excess detergent. it can.

The spray nozzle 35 is configured to spray hot water in a mist form so as to wrap the entire body, and cross-sectional views are shown in FIGS. 4 (a) and 4 (b). The spray nozzle 35 is provided with an inlet 64 through which hot water flows, a swivel tip 65, a swirl chamber 66, and an ejection hole 67. The swivel tip 65 is provided with swirl holes 68 for imparting a swirl force to three fluids on the same circumference. In FIG. 4 ( b ), a center hole 69 that forms a central axis flow of the swirling flow is provided at the approximate center of the swirling hole 68. The swirl chamber 66 is provided on the downstream side of the swirl tip 65 and the swirl flows swirled in the swirl holes 68 are confused to stabilize the swirl flow. In FIG. 4 ( b ), the hot water is ejected from the ejection hole 67 with a swirling flow and a central axial flow, so that the spray is conical and is distributed substantially uniformly. In FIG. 4 ( a ), the spray is conical because it is ejected from the ejection hole 67 with only a swirl flow, but hot water is distributed only in the surroundings in a hollow state.

  Here, since it is ejected into the atmosphere from the narrow ejection hole 67 at once, the hot water in the pressurized state is rapidly decompressed. When the gas is dissolved more than the saturated dissolution amount at the atmospheric pressure of hot water, the gas amount dissolved above the saturated dissolution amount at atmospheric pressure becomes fine bubbles at a stretch and is deposited in the spray particles of the hot water. It becomes spray particles containing fine bubbles and is sprayed so as to enclose the user 36. When the detergent is mixed in the hot water, the fine bubbles become stronger detergent bubbles due to the action of the detergent surfactant and adhere to the body surface of the user 36.

  Desirably, the particle size of hot water required to form bubbles in the sprayed particles to form detergent foam is 50% or more (preferably 70% or more) in the range of 50 to 800 μm. 66 and the ejection hole 67 are set so as to satisfy the above specifications. In the present embodiment, the number of the swirl holes 68 is three, but the present invention is not limited to this as long as the hot water and the water can be distributed in a wide range.

  The operation unit 70 shown in FIG. 3 has a water-resistant structure and includes a button and a display unit. The operation unit 70 is portable and is usually stored in the remote control holder 71 of the cover 30, but the user 36 can be removed from the remote control holder 71 and operated by hand. In this embodiment, the operation unit 70 is connected to the control unit 90 by a remote control cable 72 (wired), but the operation unit 70 is not limited to this as long as it has a wireless (wireless) configuration and the operation is the same.

  As shown in FIG. 5, the operation unit 70 is provided with the following buttons and a display unit. Each time the operation button 73 is pressed, the “operation state” and the “stop” state of the cleaning device can be switched. When the body shower button 74 is pressed in the “running state”, the water stop electromagnetic valve 42 is opened, and the spray can be sprayed from the spray nozzle 35. Further, when the hand shower button 75 is pressed in the “driving state”, water can be discharged from the hand shower 58. When the bubble button 79 is pressed during spraying from the spray nozzle 35 or while discharging water from the hand shower 58, the gas control valve 45 is opened, gas is mixed into the hot water, and spray or shower containing fine bubbles comes out. Further, when the washing button 80 is pressed during spraying from the spray nozzle 35, the detergent control valve 50 is opened with the gas control valve 45 opened, and the detergent is mixed into the hot water together with the gas. Can produce detergent foam. At this time, the detergent adjustment valve 50 is opened for a certain period of time and then automatically closed to stop the mixing of the detergent. After the fixed time has elapsed, the water stop solenoid valve 42 is automatically closed to stop spraying. Each stop method, switching method, reuse method, and the like are not particularly described in the present embodiment because various usability can be supplied by a control procedure of a microcomputer (not shown) built in the control unit 90. Further, the temperature can be adjusted by pressing the temperature adjustment buttons 76a and 76b during spraying or hand shower water discharge. At this time, the set temperature can be confirmed with an indicator 77 constituted by LEDs. Further, the flow rate can be adjusted by the water amount adjustment buttons 78a and 78b. In the present embodiment, the type and arrangement of buttons as in the operation unit 70 are used. However, the present invention is not limited to this as long as equivalent operability can be ensured.

  The mixing valve 40 is configured to mix the amount of hot water and the amount of water by an electric actuator (not shown) in response to a signal from the control unit 90 in order to mix with the mixed water temperature set by the operation unit 70. The Mr. 41 sends the temperature of the mixed hot water as an electrical signal to the control unit 90, and if there is a difference from the set temperature, the control unit 90 issues a command to the mixing valve 40 so that the set temperature is reached. The mixing valve 40 and the thermistor 41 perform feedback control. In addition, when the detected temperature is too high or too low than the set temperature, the drain valve 61 is automatically operated to discharge from the cleaning pipe 59 to the outside of the cleaning device in order to prevent the danger of the user 36. Has been.

The configuration will be described again with reference to the block diagram of this embodiment shown in FIG. 6. The water supply pipe 38 and the hot water supply pipe 39 are connected to the mixing valve 40 in the pipe. The mixed hot water passes through the thermistor 41 and is connected to the water stop solenoid valve 42. When the water stop solenoid valve 42 is opened, the hot water passes through the pressurizing device 43, the dissolution tank 52, and the flow rate detection device 55 and passes through the switching valve 56. The flow rate is calculated by the control unit 90 based on a signal transmitted from the flow rate detection device 55, and the operation of the pressurizing device 43 and the rotation speed control can be performed. The flow path is switched to the spray nozzle 35 or the hand shower 58 by the switching valve 56. On the other hand, the flow rate of the gas is adjusted by the governor mechanism 46, and mixed into the hot water before the pressurizing device 43 through the gas control valve 45. The detergent stored in the detergent tank 49 is mixed with gas through the detergent regulating valve 50 and before the gas regulating valve 45, and is mixed into hot water. The drain valve 61 disposed in front of the switching valve 56 automatically performs a drain operation under the set conditions, and can ensure the safety and convenience of the user.

  The electrical system is composed mainly of the control unit 90, with a mixing valve 40, a thermistor 41, a water stop solenoid valve 42, a pressurizing device 43, a gas control valve 45, a detergent control valve 50, a flow rate detection device 55, a switching valve 56, a drain valve. 61, which is organically coupled to the operation unit 70 and the like, and realizes control so that the cleaning device is brought into an optimum use state.

  About the washing | cleaning apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  As shown in FIGS. 1 and 3, first, the user 36 supplies a specified amount (necessary amount) of detergent to the detergent inlet 51 of the cover 30. For the sake of explanation, the user is a person who operates and sits down and takes a spray or shower, but if the elderly or disabled person is being cared for, the person who operates and the person who bathes will be expressed as a user even if they are different. It shall be. The user sits on the chair portion 33, rotates the arm portion 32, moves the arm portion 32 to an appropriate position where the spray wraps around the body, pushes the operation button 73 of the operation portion 70, and pushes the body shower button 74. When the temperature of the mixed hot water is close to the set temperature by operating the water stop solenoid valve 42 and the pressurizing device 43 in accordance with a command from the control unit 90, the water is sprayed from the spray nozzle 35. When the temperature is outside the set temperature, the drain valve 61 is operated, and the hot water passes through the discharge pipe 59 and is discharged out of the cleaning device through the drain port 63. At this time, the hot water sprayed is only the hot water supplied from the hot water supply device 37. The spray of hot water of about 42 ° C. enveloping the user envelops the user, and the user continues to bathe this so that a thermal effect appears for the user.

  When the user presses the bubble button 79 with the operation unit 70, the gas control valve 45 is activated, and the gas is mixed into the hot water from the gas mixing unit 44. The mixed hot water and gas are compressed and pressurized by the pressurizing device 43, and a part thereof is dissolved in the hot water. By passing through the dissolution tank 52, undissolved gas is removed, and only hot water in which the gas is dissolved is obtained. By spraying from the spray nozzle 35, fine bubbles are deposited in the spray particles, and the spray particles containing the bubbles wrap around the body surface. Because it contains bubbles, it adheres to the body surface with a softer feeling than particles that do not contain bubbles.

  When the user's body warms up and the washing button 80 is pressed at a time when the body is usually washed by bathing, the gas regulating valve 45 is activated, and the gas is mixed with hot water from the gas mixing section 44. Next, the detergent control valve 50 is operated, and the detergent stored in the detergent tank 49 is drawn by negative pressure and mixed with hot water together with gas. The detergent control valve 50 is closed after a predetermined time has elapsed so as not to suck an excessive amount. By passing through the pressure device 43 and the dissolution tank 52, the detergent is uniformly mixed with hot water and sprayed from the spray nozzle 35. Since supersaturated gas is mixed in the atmosphere, fine bubbles are deposited in the spray particles, and further, a firm bubble mass is adhered to the body by the detergent surfactant. Since the spray nozzle 35 is set to wrap around the body, the bubble mass of the detergent wraps around the whole body, and the whole body is wrapped at once with the detergent foam.

  The concentration of the detergent once increases and then decreases. For this reason, the time from when the detergent is mixed into the hot water until it is sprayed by the spray nozzle 35 is measured in advance, and a constant slightly longer than that time is set in the control unit 90. After supplying the detergent, the control unit 90 stops the spraying by stopping the water stop electromagnetic valve 42, the pressurizing device 43, the gas control valve 45, and the like according to the time constant. For this reason, if the bubble mass adhering to the body is left unattended, spraying is stopped without being washed away with hot water with a low detergent concentration, so that it slowly moves downward. The user cleans the body with detergent bubbles adhering with hands, towels, brushes, etc. If a detergent having a cleaning effect is used, there may be a case where the cleaning effect appears even if nothing is done for a while.

  After that, if normal operation or bubble operation is performed, hot water without detergent is sprayed, so that the detergent attached to the body can be washed away.

As described above, in the present embodiment, the cleaning device includes the gas mixing unit 44, the detergent supply device 48, the pressurizing device 43, and the spray nozzle 35 that are connected to each other by a pipe line, and the gas mixing unit 44 includes a hot water supply port. and by Ru with a gas supply line, the detergent required for washing a state of fine bubbles, can be attached to hard to drip.

  In addition, since the hand shower 58 is provided in this embodiment, spraying by the spray nozzle 35 or hand shower 58 can be used to wash away detergent bubbles adhering to the body. , Can be used properly according to the application.

There is also a method of disposing as shown in the block diagram of FIG. 6 is a pressurizing device 43. In FIG. 6, the pressurizing device 43 is a pump. However, in FIG. 7, the pressurizing device 43 includes a pump 91, a branching unit 92, and a venturi unit. 93 is connected in a ring shape in the water flow direction. When the pump 91 rotates, the water flow circulates in the annular pipe. The other of the branch portions 92 is connected to the dissolution tank 52. Hot water from the hot water supply device 37 is connected to the vicinity of the minimum inner diameter portion 94 where the flow velocity of the venturi portion 93 is maximized and the negative pressure to be sucked is maximized, and is mixed with circulating water. The amount of mixed water becomes equal to the amount of water flowing out from the branch portion 92 to the dissolution tank 52. Even if gas or detergent is mixed in the sucked hot and cold water, the operation is the same as in the above embodiment. In this configuration, since the back pressure rises because the pump 91 circulates, the pressure on the discharge side of the pump can be increased, so that a pump with a low lift can be used. In addition, due to the circulation of the mixed water of gas and hot water, and the effect of stirring and mixing in the venturi section 93, the gas is easily dissolved in the hot water and it is easy to obtain hot water in which the gas close to the saturation amount is dissolved. .

(Embodiment 2)
FIG. 8 is a block diagram of the cleaning apparatus according to the second embodiment of the present invention. 6 and FIG. 7 in the block diagram of the cleaning device of the first embodiment is that the detergent tank 49 and the detergent adjustment valve 50 are directly connected to the hot water pipe. Although it is connected in front of the pressurizing device 43 in FIG.

  In the cleaning device of the first embodiment, the suction of the detergent depends on the suction by the negative pressure of the gas mixing unit 44. However, in the cleaning device of the second embodiment, the detergent adjustment valve 50 ensures the predetermined amount. Can be mixed in hot water.
