BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a mist generator to which the present invention is applied will be described below.

FIG. 1 is a schematic configuration diagram of a mist generating device according to an embodiment of the present invention. The mist generating device 1 is placed on the floor of a bathroom and extends from a branch pipe 4 at the base end of a hot water tap 2 in the bathroom. A hot water supply hose 6 is connected to the inflow pipe 3 of the mist generator 1.

In the mist generating device 1, the supply passage 5 extends from the inflow pipe 3 to reach the central opening 9 of the mist generating disk 7. The mist generating disk 7 is for rotating hot water to atomize it, and is also provided with an impeller 11 as a blower for discharging mist. A plurality of collision plates 13 are arranged outside the mist generating disk 7 in the circumferential direction in order to further miniaturize the scattered mist and guide the direction thereof. The mist generating disc 7 and the collision plate 13 are housed in the inner casing 15. A motor 17 is attached to the outer frame of the inner casing 15, and a motor output shaft 19 passes through a shaft sealing device 21 in a through hole of the inner casing 15,
It is connected to the bottom of the mist generating disk 7. The outer casing 23 is provided with a discharge port 25 for discharging the mist to the outside. As a whole, this constitutes an atomizing device integrated with the blower.

On the other hand, from the middle of the supply channel 5 to the drainage channel 27

A hot water supply valve 31 is provided at an appropriate position of a portion of the mist generating disk 7 reaching the central opening 9, and a drain valve 33 is provided at an appropriate position of the drainage flow path 27. A drain drain pipe 37 extends from the bottom of the inner casing 15 and is guided to the outside of the mist generator 1.

An operation switch 39 and an operation lamp 41 are attached to appropriate positions on the outer surface of the mist generating device 1, and these are wired to the control device 43 inside the device 1.
A buzzer 45 for alarm is also provided. Power supply (battery)
The control device 43 connected to the 47 includes a motor 17, a hot water supply valve 31, a drain valve 33, a flow rate sensor 34, and a temperature sensor 35.
Etc. are also wired.

In the mist generator 1 having the above structure, an example of operation control performed by the controller 43 according to the present invention will be described with reference to the flow chart shown in FIG. 2 and the time chart shown in FIG.

First, when the operation switch 39 is turned on (S1), it is judged whether or not the ON state has passed for 2 seconds or more (S2), and if it is less than 2 seconds, the delay time timer is started ( After the timer reaches a predetermined delay time (S3), the motor 17 is started to generate a mist (S5).

Here, the delay time used in steps S3 and S4 is sufficient for the user who has turned on the operation switch 39 in the clothes state to leave the position where mist is not applied, or the hot water supplied from the hot water supply source. Thus, it is set based on the time that is sufficient for all the accumulated water in the supply flow path 5 to be discharged.

Returning to the flowchart, step S2
In the case of 2 seconds or more, the motor 17 is started and the mist is generated without setting the delay time (S
5).

Thereafter, when the operation switch 39 is turned on again (S6), the motor 17 is stopped to stop the mist generation (S7), and then the process returns to step S1 to continue the processing.

In addition to the above embodiments, the present invention can be used in the following embodiments. That is, in step S2 of the above-described flowchart, the user's own input method (whether the ON state is 2 seconds or more) is determined, but instead of this, when the detected temperature of the temperature sensor 35 is less than 40 ° C. Is to wait for the detected temperature to reach 40 ° C. or higher and then start the motor 17 to generate mist (S5). Such processing prevents the user from being exposed to cold air.

As another embodiment, step S7
A timer is provided to measure the elapsed time from when the generation of mist is stopped to when the operation switch 39 is turned on in step S1, and whether the elapsed time is 15 minutes (or 30 minutes) or more instead of step S2. 15 minutes (or 30 minutes)
If it is equal to or more than a minute), the delay timer can be started (S3), and if not, the motor 17 can be started and mist can be generated without providing the delay time (S5).

Here, 15 minutes is the time determined based on the average bathing time of the user, and the elapsed time is 15 minutes.
When the operation switch 39 is turned on in less than a minute, the atomizing device is immediately started assuming that the user is reusing it while bathing, that is, the user is not wearing the clothes.

On the other hand, when the operation switch 39 is turned on after the elapsed time of 15 minutes or more, it is considered that a new user has performed an on operation in a clothes state, and the delay sufficient for the user to move to a position where the mist is not applied. After a lapse of time, mist is generated (S5).

During 30 minutes, 40 minutes of hot water in the supply channel 5
It is an estimated time until the temperature becomes lower than 0 ° C, and when the operation switch 39 is turned on after the elapsed time of 30 minutes or more, it is considered that the hot water is lower than 40 ° C, and the hot water supplied from the hot water supply source The user is prevented from being exposed to cold air by generating a mist after a delay time sufficient for discharging all the accumulated water in the passage 5 (S5).

In the above embodiment, the case where the delay time is provided and the case where the delay time is not provided are distinguished according to various conditions. However, the delay time is changed stepwise according to various conditions. You can take it.
