Description of the Related Art Conventionally, as a hot water washing toilet seat of this kind for drying the anus which has become wet by washing after toilet, as shown in FIG. 7, for example, warm air heated by an electric heater is used. It is common to apply the buttock to the buttocks and dry.

In the figure, 1 is a toilet bowl, 2 is a washing device (not shown), and a warm water washing toilet seat body having a washing nozzle 5 protruding into the toilet bowl 1 for washing the anus 4 of the human body 3, and a body 2 The toilet seat 6 and the toilet lid 7 are rotatably attached to the. Reference numeral 8 denotes a drying device built in the main body 2, which includes a blower 9, a heater 10 and a blower duct 11.
It consists of

In the above structure, after cleaning by the cleaning nozzle 5 protruding from the inside of the main body 2 so as to be located below the anus by the motor or the like in the toilet 1, the heater 9 is heated by turning on the drying switch (not shown). And the blower 8 was driven, and warm air was supplied from the rear of the human body as shown by the arrow A to dry the anus. Further, as described in Japanese Patent No. 625291, a high-pressure air passage is provided in the toilet seat, and a plurality of air ejection nozzles are provided in the toilet seat to inject high-pressure air to the anus.
In some cases, a nozzle is provided on the front side of the toilet seat to inject air from the front through a high pressure air passage in the toilet seat.

[0005]

However, in the above-mentioned conventional structure, when the water droplets after washing the anus are attached to the skin around the anus or the like, the ventilation duct provided in the body behind the buttocks is used. It is a method of drying by applying hot air of about 40 ° C that is blown out, but the hot air is blown out from a fixed position behind the buttocks in the sitting position as shown by arrow A, and flows by stroking the buttocks surface, the anal area. Since it does not hit directly, it takes a very long time to dry the attached moisture,
Further, there is a problem that the user feels irritated and distressed by the monotonous feeling during use. Also, since the temperature of the skin is increased and the moisture is evaporated to dry the skin with a large amount of water on the skin surface, the skin becomes over-dried and itchy,
There are also problems such as rashes.

On the other hand, the method of ejecting high-pressure air from the toilet seat is slightly effective in terms of time reduction, but the angle of the nozzle position with respect to the anus cannot be freely adjusted, and the vicinity of the center of the anus becomes weak. In addition, a satisfactory drying effect cannot be obtained due to the distance from the anus and the jet flow becoming weaker, and the manufacturing problems such as high pressure resistance and sealing of the toilet seat itself are significant. It is scarce.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a cleansing toilet seat that is comfortable and that can be dried in a short time and provides a dry feeling.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a cleaning water supply means having a cleaning nozzle for ejecting cleaning water toward a portion to be cleaned in a main body, and intermittently supplying pressurized air. An air injection unit communicating with a drying nozzle holder having a drying nozzle for injecting into a nozzle, a warm air supply unit communicating with a warm air duct integrally formed with the drying nozzle holder, a drying nozzle holder and a warm air duct. The drive mechanism unit for driving, the cleaning water supply unit, the air injection unit, the warm air supply unit, and the control unit for controlling the drive mechanism unit are provided.

According to the above invention, since the drying nozzle holder and the warm air duct are integrally formed and driven by one driving mechanism, the drying nozzle and the hot air outlet are provided below the anus and the buttocks around the periphery. It is possible to move it, and it is possible to blow off water droplets and water films adhering to the anus and surrounding buttocks surface with pressurized air from a short distance,
Moisture remaining thinly on the skin surface after being blown off can be sprayed with warm air from the outlet at a closer distance, so that it can be dried reliably and the time can be greatly shortened. The feeling can be improved.

Further, water droplets adhering to the skin surface of the human body can be blown off with pressurized air to drastically reduce the amount of water and dry with warm air. It is possible to reduce problems such as itching and rash on the skin that occur when the temperature of warm air is increased to dry the water.

Further, since the hot air duct and the drying nozzle holder are integrally formed, the occupied area when the main body is housed can be made small and the drive mechanism can be made one.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 has a cleaning water supply means having a cleaning nozzle for ejecting cleaning water toward a portion to be cleaned in a main body, and intermittently injects pressurized air. Air injection means communicating with a drying nozzle holder having a drying nozzle at its tip, warm air supplying means communicating with a warm air duct integrally formed with the drying nozzle holder, and driving for driving the drying nozzle holder and the warm air duct By providing the mechanism section, the cleaning water supply means, the air injection means, the warm air supply means, and the control section for controlling the drive mechanism section, the drying nozzle for intermittently injecting the pressurized air was provided at the tip. A warm air duct that blows out warm air together with the drying nozzle holder can be simultaneously advanced into the toilet by the drive mechanism, and pressurized air is intermittently jetted below the buttocks and the surrounding buttocks, and from the vicinity of the portion to be cleaned. Warm Since it can be continuously sprayed, pressurized hair is jetted while shaking the hair that is stuck with the water after washing with warm air, and water drops and water films that adhere to the anus and surrounding buttocks are removed. Of course, by blowing off, the synergistic effect can blow off even the moisture attached to the root part by surface tension, and the drying can be performed reliably and the time can be greatly shortened, and the dry feeling can be improved.

Further, since hot air drying can be performed in a short time while the water content is greatly reduced by blowing off, it is possible to leave the skin surface with a large amount of water for a long time as in the conventional case.
Itching of the skin that occurs when the warm air temperature is raised to dry the skin,
Problems such as rash can be reduced.

Further, since the outlet of the hot air can be brought closer to the portion to be cleaned, the input of the hot air heater of the hot air supply means, the air flow rate of the blower, etc. can be reduced, and energy saving can be achieved.

According to the second aspect of the present invention, the hot air supply means and the hot air duct are connected by the expansion joint, and the drying nozzle holder is formed in the movable hot air duct.
Since only the hot air duct can be moved by fixing the hot air supply means having the power supply lead wire, there is no disconnection or entanglement due to the movement of the lead wire, safety is improved, and the hot air duct length is shortened. It can be pulled out into the toilet bowl and can be stored inside the main body without any problems. Also, since the drying nozzle holder can be moved along with the movement of the hot air duct,
The length of the drying nozzle holder can also be shortened.

According to a third aspect of the present invention, the drying nozzle has a wall portion in a direction substantially perpendicular to the axial direction of the drying nozzle holder, and has a plurality of injection holes formed substantially horizontally, so that the object to be washed is cleaned. Since the area where the blast air hits the part in the left-right direction in addition to the front-back movement direction is expanded, it is possible to further quickly dry the anus part and a wide range around the anus part.

According to the fourth aspect of the present invention, the hot air duct has a structure in which the outlet of the hot air duct is opened so as to face the wall portion of the drying nozzle. Since warm air can be blown from below onto the portion to be cleaned, the warm air drying efficiency is improved and the drying time is shortened.

According to a fifth aspect of the present invention, the controller moves the injection hole of the drying nozzle from the storage position to a preset injection start point at the start of drying, and operates the warm air supply means from the injection start point to the injection end point. Then, the drying nozzle is controlled to reciprocate a plurality of times while operating the air injecting means and intermittently injecting the pressurized air while continuously ejecting it from the outlet, so that the dry nozzle has a buttock region where water droplets are not attached. Simply move and start jetting and warm air drying from the area where the water droplets are attached. After that, the operation of returning to the initial storage position is performed by reciprocating a plurality of times while intermittently ejecting only the water droplet adhesion area.
As a result, while intermittently injecting pressurized air, water droplets are blown off sequentially from the injection origin, which is one end of the portion to be cleaned, and hot air is blown, and then the remaining water droplets are ejected from the other end, which is the injection end point. It blows away and returns to the injection origin. Then, a preferable dry state can be realized by reciprocating while pressurizing air is intermittently jetted together with warm air drying on the almost removed buttocks surface.

According to a sixth aspect of the present invention, the injection start point is set from the anus to the front of the human body, and the controller moves the injection hole of the drying nozzle to the injection origin of the front of the human body at the same time as the start of drying. After that, by controlling the multiple reciprocating drive between the injection end point of the rear part of the human body through the anus part while intermittently injecting the pressurized air, the injection is intermittent from the front part of the anus part toward the rear part of the human body. Since it is advanced to, it is possible for a person who does not want to wash the anus washing water droplets to the front part of the human body with peace of mind.

According to a seventh aspect of the present invention, the control unit controls the injection path to be different between the forward path and the return path during the reciprocating drive so as to compensate the position during the intermittent injection of the pressurized air. Pressurized air can be applied to, and the blowing air can be applied uniformly without coming out.

According to the eighth aspect of the present invention, the moving speed of the drive mechanism can be varied, so that the speed is increased in the non-jetting region and the speed is increased in the region where the water droplet amount is large. It can be dropped and moved, and the drying efficiency can be improved in the same drying time.

According to the ninth aspect of the present invention, the control section stops the energization of the warm air heater after the completion of the drying operation and energizes only the blower to blow the cool air to the anus. If moisture remains in the area, a cold air feels a tingling sensation, and if almost no water remains, it does not feel a tingling sensation, so that it can act as a simple dryness detecting function.

According to the tenth aspect of the invention, the hot air is blown for a certain period of time at the drying nozzle storage position after the drying operation is completed, so that the moisture adhering to the drying nozzle is dried with the warm air during the drying. It is possible to prevent dirt from adhering to the drying nozzle.
