Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an improvement of a warm air equipment hot water washer.

[Conventional technology]

Among hot water washers, one equipped with a hot air device that has the function of washing private parts of the human body with hot water and then drying them with warm air has been devised and put into practical use. A hot water washer with a hot air function is used by fixing the body above the toilet bowl, so the external shape needs to be small, and the built-in hot air fan also needs to be built into a small space.

The hot air blowing capacity of a hot air fan is determined by the rotation speed of the motor, the size of the fan, the size of the case containing the fan, etc., but it is also determined by the pressure drop of the air and the ability of the air to be sucked into the hot air fan. Depends on it.

In other words, if the hot air fan does not suck in enough air, no matter how much the fan is rotated, it will just run dry and the air blowing capacity will be reduced.

As shown in FIG. 6, a conventional hot air fan for a hot water washer is provided with an air intake only on either the upper side or the lower side with respect to the rotating surface of the fan. In addition, the fan is made by punching out a bowl-shaped side wall made of stainless steel or the like, leaving a plurality of oval parts, and bending the punched pieces inward to form blades. A motor shaft was connected to the part to rotate it.

[Problem that the invention seeks to solve]

In the configuration of this conventional hot air fan, the size of the hot air fan is limited because it is placed in a small space inside the hot water washer, and the area of the air intake is small compared to the fan capacity, resulting in insufficient air intake capacity. There were drawbacks.

Furthermore, when the fan applies suction from one side to the rotating surface of the fan, the fan applies a force in the thrust direction to the motor shaft, which has the disadvantage that the life of the bearing that supports the motor shaft is shortened.

Furthermore, vibrations due to rattling in the thrust direction of the motor tend to occur, causing noise.

To provide a warm air equipment hot water washer according to the present invention, which has a large air intake capacity even when installed in a smaller space than a conventional hot air fan, is easy to assemble, and is less likely to malfunction. The purpose is to

[Means for solving problems]

The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 5 corresponding to the embodiments.
In a hot air machine that has a built-in fan, heater, etc. and consists of an upper case and a lower case, the upper and lower cases (1) and (2)
Openings (4) and (5) are provided in the upper case (1), and a circular partition plate (9) is provided in the vicinity of the opening (4) and perpendicular to the motor shirt (11). A motor (
3) and fixed the upper case (1) to the main body chassis (6) by providing a gap between the lower case (2) and the main body chassis (6).

[Effect]

The present invention uses the above-mentioned means to fix the motor 3 to the upper case 1 by passing the screw 7 through the motor 3 near the opening 4, and fixing the motor 3 to the upper case 1 with the nut 12.
Fixing pieces 18, 18... provided on the upper case 1 are fixed with screws 7 to protrusions 19 provided on the main body chassis 6 with a gap provided between the lower case 2 and the main body chassis 6.

Therefore, when the motor 3 rotates, the fan 8 fixed to the motor shaft 11 rotates and sucks air through the upper case opening 4 and the lower case opening 5. Further, the air is heated by a heater 15 in the space formed by the upper case 1 and the lower case 2, and the temperature is controlled to an appropriate temperature by a sensor 16 fitted and fixed to the upper case 1 and the lower case 2. Air is emitted from the air outlet 14.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5.

The upper case 1 and the lower case 2, which have an opening 4.5 for air intake and an outlet 14 for blowing out air, are fitted together by a plurality of fitting parts 13 of the lower case 2, and the upper and lower openings 17 are connected to each other. A fan 8 interlocked with the motor shaft 11 of the motor 3 fixed on the opening 4 of the upper case 1 is fixed in the case between the parts 4 and 5, and the fan 8 and the air outlet 14 are connected to each other.
This hot-air fan has a built-in heater 15 that heats the air between the two. Reference numeral 18 denotes a plurality of fixing pieces arranged at appropriate locations around the upper case 1 to fix the upper case 1 of the warm air fan 17 to the protrusion 19 of the main body chassis with screws 7.

8 is the motor shaft 1 shown in FIGS. 4 and 5.
This is a fan in which a plurality of blades 10 are formed in a circular shape symmetrically on the upper and lower surfaces around a disk-shaped partition plate 9 perpendicular to 1.
is a sensor provided near the outlet 14 of the hot air fan 17.

A hot air fan 17 consisting of an upper case 1 and a lower case 2
A gap is provided between the lower case 2 and the main body chassis 6, and the plurality of fixing pieces 18 of the upper case 1 are fixed to the plurality of protrusions 19 of the main body chassis 6 using screws 7 in a hollow state.

Furthermore, by forming the upper case opening 4 and the lower case opening 5 to have approximately the same circumferential length and forming concentric circles around the motor shaft 11, approximately the same amount of air can be sucked in from above and below. Therefore, it is desirable. Further, blades 10 are formed symmetrically in the upper and lower planes with respect to the partition plate 9, and the motor shaft 1
By installing the fan 8 orthogonally to the upper case opening 4 and the lower case opening 5, when the fan 8 rotates, the air blowing capacity of the fan 8 is almost equal between the upper and lower sides with the partition plate 9 separated. The amount of air sucked in can be approximately equal.

[Effect of idea]

The present invention achieves the following effects with the above configuration.

1) By providing air suction ports in both the upper and lower cases, a hot air fan with sufficient air intake capacity can be created even if the hot air fan is made smaller.

2) The upper and lower cases are integrated by fitting without using screws or other fastening means, so even if there is some looseness between the upper and lower cases, the upper and lower cases can be easily connected to the upper case where the motor is attached, which is the source of vibration. Since the case is directly fixed to the main body chassis with screws, the vibration of the hot air fan that integrates the upper and lower cases is suppressed, eliminating noise and loosening of screws.

3) The fan shape is symmetrical in the top and bottom with respect to the partition plate 10
By attaching the partition plate orthogonally to the motor shaft, the amount of air sucked in from the upper and lower case openings is almost equal, and the partition plate receives approximately equal wind pressure from above and below, allowing the motor shaft to be pushed up. , the force in the thrust direction of the motor pushing down is reduced (the life of the remoter bearing is extended, and the vibration and noise of the motor due to rattling in the thrust direction are reduced).
