Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a nozzle for a sanitary washing device that is employed in a sanitary washing device that cleans local parts of a human body.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, a nozzle body 3 having a water channel 2 whose upper end is opened as a discharge port 1 is supplied with hot water into the water channel 2 to be ejected upward from the discharge port 1. A sanitary washing device nozzle B that can wash a local part of a human body with hot water is known. The sanitary washing device nozzle B is connected to the tip of a nozzle mounting pipe that projects from the sanitary washing device mounted on the toilet bowl so as to be able to advance and retreat. 3 is inserted and fitted to the tip of the nozzle mounting pipe.
[0003]
Further, the water channel 2 in the nozzle body 3 opens upward as a discharge port 1 in the vertical direction, and communicates with the nozzle mounting pipe through the connection cylinder portion 16 in the lower direction. The water channel 2 branches to both sides thereof. A path 21 is provided in communication. Therefore, when hot water is supplied from the nozzle mounting pipe into the water channel 2 through the connecting tube portion 16, the hot water is ejected from the discharge port 1 while vibrating so as to freely swing the head to both sides. Therefore, in this case, the local part of the human body can be washed with the hot water ejected while vibrating from the discharge port 1, and at this time, the area to be vibrated is washed as the hot water ejection range (cleaning area).
[0004]
[Problems to be solved by the invention]
However, in the above prior art, although the hot water ejected from the discharge port 1 vibrates to both sides, the ejection range (cleaning area) due to the vibration does not change, and the water particle size of the hot water is constant. There is almost no change. Therefore, when washing and removing stool or filth adhering to the local part of the human body, the washing area is limited, and since the form of hot water is not changed, sufficient washing is not performed. There has been a problem that stool or filth that has entered the inside cannot be completely washed away.
[0005]
The present invention was invented to solve the above-described problems in the prior art, and the problem was that the sanitary washing apparatus can obtain a sufficient washing action by changing the jetting range and jetting mode by flowing water pressure. It is to provide a nozzle.
[0006]
[Means for Solving the Problems]
According to a first aspect of the present invention, there is provided a nozzle for a sanitary washing device, wherein a nozzle body having a water channel having an upper end opened as a discharge port is provided with a throttle port portion at substantially the center in the discharge port, and the same around the throttle port portion. A discharge port is formed as a direct injection port, and a valve body that can be moved up and down by a change in flowing water pressure is provided in the water channel of the nozzle body so that it can be slid up and down. Only the mouth is opened and closed.
[0007]
Therefore, in this case, the hot water flowing in the water channel of the nozzle body is diffused after being squeezed by the throttle port portion from the substantially central throttle port portion of the discharge port opened at the upper end of the water channel, and is spread over a wide range in a mist form. In order to surround this, it is likely to be ejected directly from the direct injection port portion around the throttle port portion. In addition, when the flowing water pressure flowing in the water channel becomes strong, the valve body provided slidably up and down in the water channel rises and the direct injection port portion is closed, and conversely, when the same flow water pressure becomes weak, The valve body is lowered and the direct injection port portion is opened. At this time, the throttle port portion remains open.
[0008]
That is, when the amount and the water pressure of the hot water supplied into the water channel of the nozzle main body change, the flowing water pressure of the hot water flowing through the water channel also changes, whereby only the direct injection port is opened and closed by the valve body. In this case, when the flowing water pressure is weak and the direct injection port is opened, the hot water that is about to erupt over a wide area in the form of a mist from the constriction port of the spout is directly applied from the direct injection port so as to surround it. It is restrained by the hot water that is ejected, and as a whole, hot water is ejected directly from the outlet. On the contrary, when the flowing water pressure is strong and the direct injection port portion is closed, the hot water is ejected in a wide range in a mist form only from the throttle port portion of the water discharge port. Therefore, the ejection range and the ejection form are changed by the flowing water pressure, and a sufficient cleaning action can be obtained.
[0009]
The nozzle for a sanitary washing device according to claim 2 of the present invention is the nozzle for a sanitary washing device according to claim 1, further comprising a spring material that elastically biases the valve body downward, and the valve body is made of running water. It is characterized in that it is moved up and down in response to a change in pressure.
[0010]
Therefore, especially in this case, since the valve body is slid up and down in response to the change in flowing water pressure in the state of receiving the elastic force of the spring material, the direct injection port portion is not completely opened or closed. In this state, the hot water sprayed directly from the direct spray port and the hot water which is about to be sprayed in a wide range from the throttle port are moderately suppressed, and the spray range and form are analyzed in an analogy manner. It can be changed to give subtle variability to the cleaning action. Further, by adjusting the elastic coefficient of the spring material, it is possible to appropriately cope with a large amount of hot water supplied into the water channel and a high pressure.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show an embodiment corresponding to all of Claims 1 and 2 of the present invention, and a sanitary washing device nozzle A according to the embodiment has a nozzle body having a water channel 2 whose upper end is opened as a discharge port 1. 3, a throttle port portion 4 is provided substantially in the center of the discharge port 1, and the same discharge port 1 around the throttle port portion 4 is formed as a direct spray port portion 5, and is formed in the water channel 2 of the nozzle body 3. A valve body 6 that is moved up and down by a change in flowing water pressure is provided so as to be slidable up and down. By the valve body 6, only the direct injection port section 5 is opened and closed while the throttle port portion 4 remains open. .
[0014]
In the sanitary washing device nozzle A of the present embodiment, a spring material 7 is provided for elastically biasing the valve body 6 downward, and the valve body 6 is slid up and down in response to changes in flowing water pressure. Like that. Further, the valve body 6 is formed as a vane structure in which the flowing water has a mist shape by reducing the water particle size.
[0015]
Moreover, the sanitary washing device nozzle A according to this embodiment is employed in a sanitary washing device 9 attached to the toilet bowl 8, as shown in FIG. The sanitary washing device 9 includes a casing body 10 that contains a device for heating the washing water to make warm water or blowing warm air, and the sanitary washing that jets the washing water that has become warm water to the local area. An apparatus nozzle A, an operation panel 11 for performing these operations, and a controller 12 for controlling the position of the hot water discharge and the position of the sanitary washing apparatus nozzle A based on the operation on the operation panel 11. ing.
[0016]
In this case, a toilet seat 13 and a toilet lid 14 are also attached to the casing body 10 so as to be openable and closable. The toilet seat 13 is a heating toilet seat with a built-in heater. Performed on panel 11. The sanitary washing device 9 is provided with a nozzle mounting pipe 15 projecting into and out of the toilet 8, and the nozzle mounting pipe 15 is also moved back and forth on the operation panel 11. The position of the sanitary washing device nozzle A is controlled. The sanitary washing device nozzle A is connected to the tip of the nozzle mounting pipe 15, and at this time, the connecting cylinder portion 16 protruding from the nozzle body 3 is connected to the tip of the nozzle mounting pipe 15. Inserted and fitted.
[0017]
The water channel 2 in the nozzle body 3 opens as a discharge port 1 upward in the vertical direction, and communicates with the nozzle mounting pipe 15 via the connection cylinder portion 16 in the lower part. The valve body 6 is accommodated and held in the water channel 2 so as to be slidable up and down. The valve body 6 has a slide portion 17 that forms an outer peripheral portion thereof and a vane structure that is incorporated inside the slide portion 17. And the vane portion 18.
[0018]
In this case, a ring-shaped packing material 19 is attached to the outer periphery of the slide portion 17 of the valve body 6, and the packing material 19 is slidably contacted with the inner peripheral surface of the water channel 2. The valve body 6 is smoothly slid up and down while maintaining the water tightness. At that time, the valve body 6 is slid up and down by the balance between the elastic coefficient of the spring material 7 and the water amount and water pressure arbitrarily set in the hot water supplied into the water channel 2. Further, when the hot water passes through the vane portion 18 of the valve body 6, the water particle size is reduced, and the water is flown upward in the form of a mist.
[0019]
The water discharge port 1 of the nozzle body 3 has a substantially circular shape, and a throttle port portion 4 formed of a substantially cylindrical body having an upper portion reduced and a lower portion expanded in a trumpet shape is provided at a substantially inner center thereof. An opening between the outer peripheral surface of the substantially cylindrical body and the inner peripheral surface of the water discharge port 1 is formed as a direct spray port portion 5. The lower end openings of the throttle port portion 4 and the direct injection port portion 5 both communicate with the water channel 2, but only the lower end opening of the direct injection port portion 5 is opened and closed by the valve body 6. In this case, a substantially circular packing portion 20 is provided at the upper end of the slide portion 17 of the valve body 6, and the packing portion 20 comes into contact with the lower end edge of the substantially cylindrical body serving as the throttle port portion 4. The lower end opening of the direct spray port portion 5 is sealed by the upper end of the slide portion 17.
[0020]
Accordingly, in the sanitary washing device nozzle A of the present embodiment, hot water flowing upward in the water channel 2 of the nozzle body 3 passes through the throttle port 4 at the substantially center of the discharge port 1 that opens at the upper end of the water channel 2. Is squeezed after being squeezed at the throttle opening 4 and then diffused and sprayed in a wide range in the form of a mist. From the direct spray opening 5 around the throttle opening 4 so as to surround it, Try to be. Further, when the flowing water pressure flowing upward is increased, the valve body 6 slidably moved up and down in the water channel 2 is raised and the direct injection port portion 5 is closed, and conversely, the flowing water pressure is weak. Then, the valve body 6 is lowered and the direct injection port portion 5 is opened. At this time, the throttle port portion 4 remains open.
[0021]
That is, when the amount and the water pressure of the hot water supplied into the water channel 2 of the nozzle body 3 change, the flowing water pressure of the hot water flowing through the water channel 2 also changes. As a result, only the direct injection port 5 has the valve body 6. It is opened and closed by. In this case, as shown in FIG. 1, when the flowing water pressure is weak and the direct injection port portion 5 is opened, the hot water which is about to be sprayed in a wide range in a mist form from the throttle port portion 4 of the water discharge port 1 surrounds it. In other words, the water is suppressed by hot water sprayed directly from the direct injection port 5, and the hot water is sprayed directly from the water discharge port 1 as a whole. On the other hand, as shown in FIG. 2, when the flowing water pressure is strong and the direct injection port portion 5 is closed, hot water is ejected over a wide range only in a mist form from the throttle port portion 4 of the water discharge port 1.
[0022]
Therefore, the jetting range and the jetting form are changed by the flowing water pressure, and a sufficient cleaning action can be obtained. Hot water is supplied into the water channel 2 of the nozzle body 3 to be jetted upward from the discharge port 1, and the jetted water is ejected. The local area of the human body can be effectively washed with hot water. In this case, by adjusting the amount or the water pressure of the hot water supplied into the water channel 2 of the nozzle body 3, the flow pressure of the hot water flowing through the water channel 2 is changed, so that a desired ejection range is obtained. And the ejection form can be easily obtained by the same operation adjustment. Further, in response to the change in the amount or the water pressure of the hot water supplied into the water channel 2 of the nozzle body 3, the flow pressure of the hot water flowing in the water channel 2 is changed by itself so that the ejection range or The jet form is automatically changed.
[0023]
In the sanitary washing device nozzle A of the present embodiment, the valve element 6 is vertically slid up and down in response to a change in flowing water pressure, particularly in a state of receiving the elastic force of the spring material 7. In the middle state where the mouth portion 5 is not completely opened or closed, the hot water sprayed from the direct spray mouth portion 5 in a direct radiating manner and the hot water which is about to be ejected from the throttle mouth portion 4 in a mist form are appropriate. Suppressing each other, the ejection range and the ejection form are changed in an analgesic manner, and subtle variability can be imparted to the cleaning action. Moreover, by adjusting the elastic coefficient of the spring material 7, it is possible to appropriately cope with a large amount of hot water supplied into the water channel 2 and a high pressure.
[0024]
Furthermore, when the amount or water pressure of hot water supplied into the water channel 2 of the nozzle body 3 is less than or equal to a predetermined value, the state shown in FIG. 1 is obtained. It is effective to set the elastic coefficient of the spring material 7 so that the state shown in FIG. In the sanitary washing device nozzle A of the present embodiment, the water particle size of the hot water flowing in the water channel 2 is reduced by the vane portion 18 of the valve body 6, and a mist-like jet is previously generated at the valve body 6. Since it is generated, the mist-like hot water is surely ejected from the throttle port 4 of the water outlet 1 in a wider range.
[0025]
【The invention's effect】
As described above, in the sanitary washing device nozzle according to claim 1 of the present invention, the flowing water pressure of the hot water flowing in the water channel is changed by the amount and the water pressure of the hot water supplied into the water channel of the nozzle body, thereby The hot water jetting range and jetting form jetted from the discharge port are also changed, so that a sufficient cleaning action can be obtained.
[0026]
Further, in the sanitary washing device nozzle according to claim 2 of the present invention, in particular, the hot water jetting range and jetting form from the discharge port are changed in an analog manner to give subtle variability to the cleaning action. In addition, it is possible to appropriately cope with a large amount of hot water supplied into the water channel and high pressure.
