Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water washing device used for sanitary equipment.

2. Description of the Related Art Generally, a shutter of a hot air outlet of a hot water washing device used for sanitary equipment such as a toilet is configured to open and close only a front outlet. That is, in FIG. 4, a weight 22 is attached to the upper-open shutter 21, and the shutter 21 is normally set up by the weight 22 to close the air outlet 23. The shutter 21 is tilted forward and the outlet 23 is opened. Further, in FIG. 5, the lower opening shutter 24 closes the outlet 25 by its own weight, and when the shutter 24 is opened by warm air, the bent portion 24a at the tip of the shutter 24 is larger than the conventional one (broken line) and completely. It is about to open. Further, in FIG. 6, in order to improve the opening of the lower opening shutter 26, a wing 28 is provided behind the rotating shaft portion 27 of the shutter 26 so that the shutter 26 can be firmly opened by warm air. .

Problems to be Solved by the Invention However, in the conventional configuration as described above, when warm air is applied well to the washing part of the body to dry in a shorter time, as shown in FIG. 5 and FIG. There is a limit to the warm air that can be rolled up with the open bottom shutters 24 and 26. However, although the above-mentioned point can be solved by the upward opening method as shown in FIG. 4, when the shutter 21 is stuck to the outlet 23 by the washing water or is pressed by the toilet seat cover or the like, the upward opening method is used. Therefore, it is possible that the heater is not opened at all, and at that time, the heater for generating hot air may overheat.

The present invention solves the above-mentioned problems, and while warm air is rolled up during drying with warm air, warm air can be discharged from the lower outlet even if the shutter is pressed by an obstacle. An object of the present invention is to provide a hot water washing device that does not overheat the heater.

Means for Solving the Problems In order to solve the above problems, the present invention provides a front air outlet and a lower air outlet for blowing warm air forward and downward at the end of a wind tunnel that guides warm air. A shutter is provided which closes the lower outlet when the front outlet is opened by the wind pressure of warm air and closes the lower outlet when the lower outlet opens when there is no temperature.

Action With the above structure, the front air outlet is closed when there is no warm air in normal conditions, and the shutter opens the front air outlet with wind pressure when drying with warm air, and the hot air is blown up so that it may hit the cleaning area well. In an abnormal case where the shutter does not open the front air outlet, the warm air is blown downward from the lower air outlet, and the problem caused by the hot air being sealed in the wind tunnel does not occur.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side sectional view of a drying hot air outlet of a hot water cleaning apparatus showing an embodiment of the present invention. FIG. 1 shows a state of a hot air outlet in a normal state, and the wind tunnel 1 guides hot air generated by a hot air drying device (not shown) equipped with a blower fan motor and a heater for drying a cleaning area. It is a thing. Further, the hot water washing device includes a feed water heating device (not shown) for supplying hot water to the jet nozzle for washing the body. At the end of the wind tunnel 1, a front outlet 2 for blowing warm air forward and a lower outlet 3 for blowing warm air downward are provided, and these front outlet 2 and lower outlet 3 can be opened and closed. Shutter 4 is wind tunnel 1
It is rotatably supported by the rotating shaft 5 at the lower end of the front end of the. The shutter 4 comprises an upper half 6 for opening and closing the front outlet 2 and a lower half 7 for opening and closing the lower outlet 3, and the weight of the lower half 7 is heavier than that of the upper half 6. During normal operation or when washing is performed in which warm air is not guided to the wind tunnel 1, the shutter 4 rotates so that the lower half portion 7 faces downward due to its own weight and the upper half portion 6 moves forward as shown in FIG. The outlet 2 is closed so that the wind tunnel 1 is prevented from entering dirty water during cleaning.

Next, during the drying by the warm air in which the warm air is guided to the wind tunnel 1, the shutter 4 is blown by the wind pressure so that the upper half portion 6 opens the front air outlet 2 and the lower half portion 7 blows downward. The outlet 3 is rotated so as to be closed so as to be in a substantially horizontal posture, and the warm air is blown up so as to hit the human body 9 well by the bent portion 8 at the tip portion of the upper half portion 6 as shown by the arrow A, and the lower outlet 3 There is also no inhalation of cold air from.

Even if the upper half 6 of the shutter 4 is pressed by the toilet seat cover 11 attached to the toilet seat 10 as shown in FIG. As described above, the air is blown from the lower outlet 3 into the lower toilet bowl. Therefore, the heater for generating warm air is not likely to overheat.

Note that FIG. 7 is an overall configuration diagram of the hot water cleaning device for easy understanding.

As described above, according to the present invention, the shutter can wind hot air by the upper opening method to improve the drying performance, and even if an abnormal situation where the shutter does not open at all due to the upper opening method occurs, the warm air is There is no problem caused by the hot air being blown downward from the lower outlet and being sealed in the wind tunnel.
It is possible to improve safety.
