Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot air drying device used in toilet bowls, etc., which blows out warm air to dry private parts after washing them with hot water.

BACKGROUND ART Conventional hot air drying devices used for toilet bowls include a toilet integrated type as shown in FIG. 1 and a stationary type as shown in FIG. 2. The integrated type toilet shown in FIG. 1 has a low tank 2 installed at the rear of the toilet 1, and a space 3 below the installed part is filled with a hot water washing device (not shown) and a warm air drying bag W.
It is used as storage space for 4. In this case, the hot air supplied from the hot air drying device 4 is ejected toward the user's private parts from an ejection port 5 that opens at the rear of the inner surface 1a of the body. In addition, the stationary type shown in Figure 2 is
A cover 7 for a hot air drying bag W4 and a hot water washing bag W (not shown) is attached to the rear of the toilet seat 6, and a hot air outlet 8 is provided in the cover 7. In this case, the hot air supplied from the hot air drying bag W4 is ejected from the air outlet 8 toward the user's private parts through the space between the toilet seat 6 and the top surface of the toilet bowl 1.

In both of the above-mentioned conventional toilet bowl-integrated and stationary hot air drying devices 4, the hot air outlets 5 and 8 are fixed. For this reason, there was a drawback that the distance from the spout ports 5 and 8 to the user's private parts was long, and it took a long time to dry. In addition, when women wash their bidets, warm water is also splashed on their pubic hair, which requires more time to dry or needs to be wiped off with toilet paper or the like. In other words, conventional hot air drying devices have not been able to fully fulfill their required original functions.

By the way, one possible way to improve the above-mentioned drawbacks is to increase the temperature and volume of hot air. However, because
If the hot air temperature is set high, there is a risk of burns to the user, and if the volume of hot air is increased, the hot air drying device itself becomes larger, which increases power consumption and electricity costs. there were.

In short, this improvement measure was unrealistic.

In view of the above-mentioned drawbacks of the conventional art, the present invention has been improved and eliminated, and includes a blower installed at the rear of the toilet bowl, an external cylinder communicating with the air outlet of the blower, and a housing housed within the external cylinder. an internal cylinder that is capable of protruding and retracting from its distal end; a spout formed at the distal end of the internal cylinder; and a heater provided in the middle of an air passage from the blower to the spout. By configuring a hot air drying device used in toilet bowls, etc. with a means for protruding and retracting the internal cylinder, hot air is ejected from a position close to the private parts according to the user's body shape, etc., and the drying time can be shortened. The aim is to make the process shorter and paperless, to achieve uniform drying, and to make the apparatus itself lighter and smaller.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

3 to 6 show a first embodiment of the present invention, and FIG. 3 shows a toilet bowl 11 equipped with a hot air drying device 10.
FIG. 4 is a plan view of the entire toilet bowl 11 in a cross section showing the main parts of the hot air drying device IO. The hot air drying device 10 of this first embodiment is of a type installed on a toilet seat 12, as shown in FIGS. 3 and 4. In the same figure,
13 is a toilet lid, and 14 is a cover for a hot air drying device 10 and a hot water washing device 15 that are integrally formed with the toilet lid 13 and the toilet seat 12. Hot air drying device 1O and hot water cleaning device 15
The nozzles 16 and 17 each face into the toilet bowl.

An operating lever 18 for the hot air nozzle 16 and its cover 19 are attached to one side of the cover 14. Further, a low tank 20 is installed on the rear side of the cover 14.

The warm air drying device 10 has a cover 14 as shown in FIG.
It has an outer cylinder 21 fixed to the outer cylinder 21, and an inner cylinder (hot air nozzle) 16 is slidably housed in the outer cylinder 21. Further, the inner cylinder 16 can freely protrude and retract from the distal end side of the outer cylinder 21. Reference numeral 23 denotes a hot air outlet drilled on the outer periphery of the upper surface on the tip side of the inner cylinder 16, and 24 denotes a heater attached to the opening side of the outer cylinder 21.

An end surface on the opening side of the external cylinder 21 is connected to an air outlet of an air blower ta (fan motor) 26 via a connecting pipe 25 .

In this embodiment, the internal cylinder 16 is moved in and out using the lever 18 and the wire 27 (see FIG. 6). The other end of the wire 27 passes through the outer cylinder 21 and is connected to the rear end of the inner cylinder 16 . 5 and 6, 28 is a tube of the wire 27, 29 is a heat radiation fin attached to the outer peripheral surface of the external cylinder 21, and 33 is a tube of the external cylinder 21.
This is a stopper installed inside. This stopper 33
is for determining the retracted position of the internal cylinder 16.

Next, the operation mode of the first practical individual package W 10 configured as described above will be explained.

First, after the user's private parts are washed by the warm water washing device 15, the blower 26 and the heater 24 are turned on. The wind generated by the blower 26 flows into the external cylinder 21 from the connecting pipe 25 and becomes warm air by passing through the heater 24. Then, it is ejected from the ejection port 23 of the internal cylinder 16. Next, the internal cylinder (hot air nozzle) 16
The operating lever 18 is moved from the state shown in FIG. 6 upward in the figure. As a result, the inner cylinder 16 moves to protrude from the distal end side of the outer cylinder 21 via the wire 27, resulting in the state shown in FIG. 5. The amount of protrusion of the internal cylinder 16 at this time can be arbitrarily determined by controlling the amount of movement of the lever 18 (stepless adjustment).
, can be freely adjusted according to the user's body shape.

That is, the user can move the spout 23 of the internal cylinder 16 to a position that suits his/her body type.

Therefore, the distance from the ejection port 23 to the user's private parts is much shorter than in the conventional case, and the pressure loss of the ejected hot air is small. Therefore, assuming that the output of the blower is constant, the wind pressure near the local area in this example is much higher than in the conventional case, and it is possible to blow away water droplets during initial drying and enhance the drying effect. Moreover,
It is possible to shorten the drying time, and it is possible to achieve a paper-free system, which is ideal for this kind of hot air drying device. Also, spout 2
The position of 3 can be changed as appropriate depending on the state of dryness of the local area, and it is possible to dry the local area and its surroundings evenly and evenly. In addition, the hot air outlet is of a nozzle type, and in addition to the effect of shortening the distance described above, the air volume can be reduced, and the entire device can be made lighter and smaller.

After the drying of the private parts is completed, the operating lever 18 is moved downward in the figure as shown in the sixth FI, the inner cylinder 16 is moved back into the outer cylinder 21, and the blower 26 and heater 24 are turned off. do it.

Next, a second embodiment of the present invention will be described with reference to FIG. This second embodiment includes a motor 30 that rotates forward and backward;
With the winding drum 3I of the wire 27, the inner cylinder 1
6 is made to protrude and retract. The other configurations, functions, and effects are the same as those of the first embodiment, so their explanations will be omitted here.

FIGS. 8 and 9 show a third embodiment of the present invention. In this embodiment, the internal cylinder 16 is moved in and out using the wind pressure of the blower 26. On the outer periphery of the inner cylinder 16, the outer cylinder 21
A return spring 32 is provided between the front end side of the inner cylinder 16 and the rear end side flange 16a of the inner cylinder 16, which always urges the inner cylinder 16 in the retracting direction (rightward in FIGS. 8 and 9).
are arranged.

In this case, the operation mode of the hot air drying device IO is such that when the blower 26 is turned on from the stopped state shown in FIG.
The internal cylinder 16 protrudes due to the wind pressure of the wind blown by the cylinder 6, and becomes the operating state shown in FIG. The inner cylinder 16 is moved back and forth by being biased by the spring 32 by turning off the blower 26. The other configurations and effects are the same as in the first and second embodiments.

FIGS. 10 and 11 show a fourth embodiment in which the internal cylinder 16 is moved in and out using water pressure. In this case, the warm air flow population 3 of the inner cylinder 16
4 has an opening 7 at its rear end on the side surface, and correspondingly, the hot air supply port 35 of the connecting pipe 25 is connected to the external cylinder 21.
There is an opening in the middle of the circumferential side. The heater 24 is placed midway within the connecting tube. Further, a water inlet 36 is provided on the side surface of the rear end of the external cylinder 21, and is connected to a water supply source (not shown) via a valve 38 by a pipe 37 branched in the middle. It is connected to a drain tank (not shown) via a valve 39. 32 is a spring for returning the internal cylinder 16.

Then, the 10th t! From the state shown in I, the blower 26 and heater 24 are turned on, the valve 38 is opened, and the valve 39 is turned off. This allows water to flow from the inlet 36 to the external cylinder
21 and causes the inner cylinder 16 to protrude.

Then, the internal cylinder 16 stops at a position where the water pressure and the urging force of the return spring 32 are balanced, and the 11th
The state of use is as shown in the figure. At this time, the internal cylinder 16
The warm air flow population 34 and the hot air supply port 35 of the connecting pipe 25 match, and the warm air heat exchanged by the heater 24 flows into the internal cylinder 1.
It is ejected from the nozzle 23 of 6. That is, local drying is performed. After drying is completed, close the valve 38,
Open valve 39. As a result, the internal cylinder 16
is biased by the return spring 32 and starts the retracting operation. Additionally, the water supplied into the external cylinder 21 is collected into the drain tank. Then, it returns to the stopped state shown in FIG. 1θ. Other effects are the same as in each of the above embodiments.

12 to 14 show a fifth embodiment in which an internal cylinder 16 is linked with a cleaning nozzle 17 of a known hot water cleaning device 15 (see FIG. 4). In this case, the inner cylinder ring 16 has two longitudinally divided chambers 40,41, the chamber 40 communicating with the cleaning nozzle 17 at the tip and the chamber 41 communicating with the hot air nozzle 42 at the tip. 43 is a cleaning water supply port formed on the circumferential side of the outer cylinder 21, and 44 is a cleaning water inlet of the internal cylinder 16. , of course in this embodiment, the warm air chamber 41
communicates with a blower 26 via a connecting pipe 25. In this embodiment, a wire 27 is used as a means for protruding and retracting the inner cylinder 16. As for this protruding and retracting means, it is also possible to use a motor, wind pressure, or water pressure, as in the second to fourth embodiments. Thus, during hot water washing, the internal cylinder 16 protrudes from the stopped state shown in FIG. 13 and enters the operating state shown in FIG. 14. Here, the cleaning water supply port 43 and the inlet 44 match, and the cleaning water is jetted from the cleaning nozzle 17 toward the private parts. After the cleaning is completed, the supply of cleaning water is stopped. After that, the blower 26 and the heater (not shown) are turned on.
Then, hot air drying is performed.

The internal cylinder 16 moves in and out after hot air drying is completed.

If this is the case, there is no need to separately prepare a means for protruding and retracting the cleaning nozzle 17, and the apparatus can be made economical and lightweight and compact. The other configurations and effects are the same as in each of the above embodiments.

By the way, although each of the above-mentioned embodiments describes the case where the hot air drying device 10 is installed on the toilet seat 12, the present invention is not limited to this, and can also be applied to a device that is integrated with the toilet bowl 11. Of course. Moreover, the means for protruding and retracting the internal cylinder 16 may be applied in addition to the above-mentioned means.

Furthermore, the hot air drying device of the present invention can also be used by being attached to a so-called private part cleaning device.

As explained above, according to the present invention, the distance from the ejection port of the internal cylinder to the user's private parts is much shorter than in the conventional case, and the pressure loss of the ejected hot air is small. Therefore, assuming that the output of the blower is constant, the wind pressure near the local area is much higher than in the conventional case, making it possible to blow away water droplets during initial drying and increase the drying effect.Moreover, the drying time is shortened. This makes it possible to achieve a paperless system, which is the ideal for this kind of hot air drying equipment.Also, the position of the spout can be changed as appropriate depending on the drying condition of the local area, so that it can evenly dry the private area and its surroundings. It is possible to dry evenly.In addition, the hot air outlet is a nozzle type, which not only reduces the distance mentioned above but also reduces the amount of air, making it possible to reduce the weight and size of the entire device. .
