[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 is composed of cleaning water supply means having a cleaning nozzle for ejecting cleaning water toward the anus, a nozzle head having an injection hole, and a nozzle body. And an air injection means communicating with the drying nozzle, the injection force of the injection hole calculated from the reference value using the injection force obtained by the product of the flow velocity 60 m / sec from the injection hole and the injection flow rate 400 cc / sec as the reference value. When the opening area is used as the reference area, the ejection force equal to or greater than the reference value and the opening area is 1 of the reference area.
Due to having injection holes that range from 2% to about 150%,
Of the residual water attached to the anus and surrounding buttocks after washing,
Water droplets are instantly blown off, and moisture adhering to the surface of the anus and the like is accelerated by high-speed air, and the time required for drying can be shortened.

According to the second aspect of the present invention, since the opening / closing means and the pressure accumulating space are provided on the upstream side of the drying nozzle and the pressurized air is intermittently injected by the opening / closing means, the air can be accumulated in the pressure accumulating space at the time of closing. The power required for the air injecting means can be reduced, and the air injecting means can be downsized and reduced in noise.

According to the third aspect of the present invention, the opening time of the opening / closing means is set to 0.2 seconds or less and the injection cycle is set to 0.5 seconds to 2 seconds, so that the effect of the pressure accumulation and the number of injections are factors. It is possible to optimize the time reduction and also reduce the auditory sense of the injection sound generated during injection.

According to the fourth aspect of the present invention, when the nozzle head is located directly below the anus, the injection length between the injection hole and the anus is set to 40 mm to 60 mm, so that the buttock shape that differs depending on the user can be obtained. It is possible to maintain the jet flow velocity at which the blowing effect can be obtained without the drying nozzle contacting.

According to the fifth aspect of the present invention, the nozzle head is movable within the lower plane of the anus portion of about 100 mm in length and width centering on the anus portion while injecting pressurized air from the injection hole, so that individual differences and cleaning strength can be improved. It is possible to cope with the range of water adhesion that occurs due to the difference in the method such as the washing pattern.

According to a sixth aspect of the present invention, there is provided a substantially T-shaped dry nozzle having a nozzle head formed in a direction perpendicular to the axial direction of the nozzle shaft body. By advancing and retracting toward the front, it is not necessary to move the drying nozzle in the anteroposterior direction of the anus, and the drying area of the entire part to be cleaned can be covered by moving only in the left and right direction, and the drying time can be shortened. Since it can be sandwiched by the jet stream from both sides centering on the part, the water is drawn toward the center side and efficiently blown off.

According to a seventh aspect of the present invention, a substantially T-shaped drying nozzle having a nozzle head formed in a direction perpendicular to the axial direction of the nozzle shaft is moved forward and backward toward the anus from the direction coaxial with the cleaning nozzle. By doing so, contrary to claim 7, it is not necessary to move the drying nozzle in the left and right direction of the anus, and like the cleaning nozzle, the entire portion to be cleaned can be covered only by moving in the front and rear direction, and the drying nozzle and the moving nozzle can be moved. The means can be housed in the flush toilet seat body.

According to the eighth aspect of the present invention, by providing the drying nozzle in which the nozzle head is formed in a size of 100 mm in length and width, the drying nozzle is moved from the inside to the anus side after the drying nozzle is moved to the left, right, front and rear. Since the entire drying area is dried immediately after the movement, it is possible to further shorten the drying time.

According to the ninth aspect of the invention, since the penetrating portion is provided around the ejection hole of the nozzle head, the water droplets dripping from the portion to be cleaned remain at the tip portion, and the buttocks are re-injected during the ejection during drying. It is prevented from scattering to the side.

According to the tenth aspect of the present invention, since the injection hole is formed so as to be closer to the anus portion than the penetration portion, even if a water droplet is dropped from the portion to be cleaned near the injection hole, it flows to the penetration portion side. Therefore, the scattering of the washing water at the time of jetting, which is a problem of the flat tip portion, is further prevented.

According to the eleventh aspect of the present invention, by providing the drying nozzle formed by meandering the nozzle head in a substantially U-shape, most of the water droplets dropped after cleaning are between the substantially U-shape nozzle heads. After being moved to the lower part of the anus part in the same manner as in claim 8, by forming a plurality of substantially U-shaped shapes in the range desired to be dried, since the particles fall through the toilet bowl and fall into the toilet bowl when sprayed. Does not need to be moved back and forth.

[0019]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1 and Embodiment 2) FIG. 1 is a schematic perspective view of a cleaning toilet seat with a drying function according to Embodiment 1 of the present invention.

In FIG. 1, reference numeral 12 is a toilet bowl, and 13 is a flush toilet seat body. On the flush toilet seat body 13, a toilet seat 14 on which a user sits and needs to be added and a toilet lid 15 for covering the toilet seat when not in use rotate. It is installed freely. Further, in the flush toilet seat body 13, wash water supply means 17 having a wash nozzle 16 for washing the anus after toilet, a nozzle shaft 18 and a nozzle head 20 provided with an injection hole 19 at the tip thereof. The air injection unit 22 that communicates with the drying nozzle 21 and the control unit 23 that controls the driving of the air injection unit 22 are provided. Reference numeral 24 is a drive unit for moving the washing nozzle 16 and the drying nozzle 21 into the toilet bowl below the anus, and is also a heat exchange unit (not shown) for producing hot water and a functional component (not shown) for ejecting hot water. It is configured.

FIG. 2 shows an air injection means 22 showing a second embodiment.
Then, a two-way solenoid valve is connected to the discharge side of the air pump 25 as a pressure accumulation space 26, and a two-way solenoid valve is connected to the drying nozzle 21 via a connection hose 28 as an opening / closing means 27 for switching the flow path between an open state and a closed state. Connected, opening and closing means 27
The pressurized air is intermittently jetted from the jet holes 19 every time the open and closed states are repeated. And FIG. 3 shows the relationship between the blowing velocity v of the pressurized air jetted from the jet hole 19 and the jet flow rate Q and the drying performance obtained by calculation based on the experimental values. The blowout flow rate v and the injection flow rate Q are used as the quantities for determining the quality of the performance (evaluated as being able to be dried when the weight of the residual adhered water after drying is a certain value or less and a feeling of dryness is felt after the drying operation). It is defined by the injection force F which is proportional to the product of The reference value Fs of the ejection force (boundary satisfying the drying performance) is v = 60 m /
sec, Q = 400cc / sec, the vertical axis is Fs
Is a value indicating the ejection force ratio (F / Fs) of F calculated with v and Q, and the ejection force ratio of 1 or more satisfies the drying performance, and 1 or less indicates that the drying performance is not satisfied.

The horizontal axis represents the opening area ratio (A) with the opening area of the above-mentioned reference value as the reference area As among the opening areas (A = Q / v) of the injection holes 19 which are uniquely determined from v and Q. / A
s) is shown. The blowout flow velocity v is a value obtained by actually measuring the injection flow rate Q and dividing it by the opening area A of the injection hole 19 because it is difficult to measure it near the outlet of the injection hole 19.

According to the experimental results, in the region where the ejection force ratio is 1 or more, large droplets of water adhering to the buttocks and pubic hair are instantly blown off, and water that is not in the form of droplets but remains in the anus or the like is also present. When the high-speed air was blown, it gradually became water droplets and was blown away. Further, the evaporation effect was added, and the result that the drying performance was satisfied in a short time of 30 seconds or less was obtained. On the other hand, in the region where the ejection force ratio is 1 or less, the ability to blow off the water droplets gradually becomes insufficient, and the evaporation speed of the adhered water also slows down, so when drying is to be completed in a short time of around 30 seconds. The result was frustrating.

Further, as shown in FIG. 3, although the injection flow rate Q is increased and the blowout flow velocity v is decreased, that is, even if the opening area A is increased, the condition for satisfying the drying performance can be obtained.
It was obtained from a subject experiment that the feeling of cold wind was strongly felt when it was dry in the winter when the air flow rate was 500 cc / sec or more. Therefore, the upper limit of Q was 500 cc / sec and the injection area ratio was 1.5. Set. On the other hand, considering mass production workability and clogging, it is difficult to make holes with a diameter of 1 mm or less, and the lower limit is 12% of the reference area (about 6.7 mm ² ).

Further, the upper limit of the injection force ratio is not set, but generally, the larger it is, the more the blowing effect is obtained. For example, the above-mentioned opening area ratio range (0.12 to 0.12).
When the injection force ratio is set to 2 or more within 1.5), the air flow rate of 70 m / sec or less requires the air flow rate of 700 cc / sec or more, and the air flow rate of 500 cc / sec or less requires the air flow rate of 1
It becomes more than 00 m / sec, and the load on the air injection means 22 side that supplies air increases, and problems such as upsizing, insufficient capacity, pressure resistance, noise, etc. occur. Setting seems desirable.

Next, in the second embodiment, by temporarily accumulating air in the pressure accumulating space 26 and injecting it intermittently, the injection flow rate for one time is about 1/10 of that at the time of continuous operation, and the blowout flow velocity is also the accumulating space 26. Since the pressure-accumulated air is instantly jetted, a high-speed flow is easily obtained, and the condition for satisfying the drying performance of the first embodiment can be achieved without increasing the load of the air jetting means 22.

Further, although not described in the examples, it goes without saying that the dry feeling and the drying time can be further improved by using the conventional hot air drying together.

(Embodiment 3) FIG. 4 shows an injection cycle of the opening / closing means 24 of the cleaning toilet seat with a drying function according to Embodiment 3 of the present invention, in which the horizontal axis represents time and the vertical axis represents injection pressure.

Since the structure and operation are the same as those of the second embodiment, the description thereof is omitted here.

In this embodiment, the opening time of the opening / closing means 27 becomes closer to a continuous flow from an intermittent flow as the opening time becomes longer, so the injection pressure decreases, and if the same pressure is attempted, the load on the air pump 25 increases. To do. Therefore, if you want to obtain a high flow velocity, it is better to inject the accumulated air in a moment.
The flow rate is reduced due to the operating performance of the opening / closing means 27 and the pressure loss, so the time is set to 0.2 seconds or less. It was confirmed experimentally that the optimum injection force can be obtained by this setting. Further, when the injection cycle is set to 2 seconds or more within a constant drying time, the number of injections within the target time is reduced and the drying performance cannot be satisfied, and the result that the target time is satisfied from 2 seconds or less was obtained. However, on the contrary, when the injection cycle is 0.5 seconds or less, it has been found that the pressure accumulation time is insufficient, a predetermined pressure cannot be obtained, and the injection noise is frequently generated, which is not preferable in terms of hearing.

(Embodiment 4) FIG. 5 shows the injection hole 19 of the toilet bowl with a drying function and the anus A of the user according to Embodiment 4 of the present invention.
It shows the positional relationship with.

In this embodiment, when the injection hole 19 is located immediately below the anus A, and the injection length (L) is 60 mm or more, the injection speed is reduced by about 10% and the drying performance is deteriorated, which is the reverse. If it is less than 40 mm, the nozzle shaft 21 pushed out obliquely from above may come into contact with the buttocks B of the user.

(Embodiment 5) FIG. 6 shows the moving range of the drying nozzle 21 as seen from the inside of the toilet 12 of the toilet bowl with a drying function according to Embodiment 5 of the present invention. Vertically (Y direction) centered on A and 1 horizontally (X direction)
