Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human body washing apparatus having a water discharge hole for jetting washing water toward a human body.

[0002]

2. Description of the Related Art Conventionally, as a means for adjusting the washing intensity according to the user's preference, a method of changing the washing intensity by adjusting the flow rate of washing water has been widely used.
As a means for adjusting the flow rate, a method of using a water pump to make its output variable or a method of providing a flow rate control valve in a flow path of washing water has been adopted.

Further, a method has been proposed in which air is forcibly mixed into cleaning water to reduce the amount of cleaning water used, and the cleaning intensity is adjusted by adjusting the amount of air mixed.

[0004] Japanese Patent Application Laid-Open No. 8-128096 discloses that air bubbles are mixed in washing water, so that the higher the mixing ratio of bubbles, the more irritant the air bubbles are. By changing the air mixing ratio at the time of bidet washing than at the time of anal washing,
There is disclosed a sanitary washing apparatus capable of obtaining a washing feeling of a strength suitable for each local part.

Japanese Patent Application Laid-Open No. 10-18391 discloses a human body washing apparatus in which the speed and the momentum of the washing water are increased by mixing air into the washing water, and the water saving rate increases as the air mixing rate is set higher. I have.

In such a washing apparatus for the purpose of water saving, in order to increase the water saving rate and to obtain a comfortable washing strength, the opening for discharging the washing water is made small, and the flow rate of the water is increased by mixing air. As a result, comfortable washing intensity is obtained earlier, and since the amount of washing water used is small, there is no need to keep the stored water warm by using means for instantaneously directly heating the washing water. It is also possible to realize energy-saving operation.

[0007]

However, in the case of using the cleaning water heating means for directly heating instantaneously, if the flow rate of the cleaning water is changed in a short time in accordance with the selection of the cleaning intensity, the temperature of the cleaning water heating means is reduced. There was a problem that the adjustment control could not follow the increase and decrease of the flow rate of the washing water, and the temperature of the washing water changed, thereby impairing the washing comfort.

In the case where the difference between the temperature of the cleaning water before heating and the temperature selected by the water temperature setting means is large, high-power cleaning water heating means is used to obtain cleaning water having a comfortable water temperature. I had to.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. By providing an air mixing means, the flow rate of washing water can be reduced, and the washing strength can be increased while maintaining the temperature of washing water stably.

Therefore, means for adjusting the flow rate of the washing water is not required. Therefore, as in the case where the washing intensity is made variable by increasing or decreasing the flow rate of the washing water, the temperature adjustment control of the washing water heating means for heating the washing water does not fail to follow the increase or decrease in the washing water flow rate. Even when the selection of the cleaning intensity is changed, it is possible to supply cleaning water having a relatively stable water temperature.

In the present invention, the temperature of the washing water is stabilized by keeping the flow rate of the washing water constant irrespective of the washing strength selected by the washing strength setting means, and the washing strength is adjusted by adjusting the amount of air mixed. The temperature adjustment control of the washing water heating means for heating the washing water cannot follow the increase or decrease in the washing water flow rate, as in the case where the washing strength is made variable by increasing or decreasing the washing water flow rate. That is, even when the selection of the cleaning intensity is changed during the cleaning, the cleaning water having a stable water temperature can be supplied.

According to the third and fourth aspects, since the flow rate of the cleaning water is set by the difference between the temperature selected by the water temperature setting means and the temperature before the heating, the cleaning water having a more stable water temperature can be supplied.

Conversely, when the temperature difference is large, the load on the washing water heating means can be reduced by reducing the amount of washing water and increasing the amount of air mixed in, and the durability of the product can also be improved.

According to the fifth aspect of the invention, the water discharge hole can be made simple by arranging the water discharge hole fixed to the cleaning nozzle body.

According to the sixth aspect, by disposing the water discharge holes in the rotating body, it is possible to obtain a high cleaning feeling over a wide area with a smaller flow rate of the cleaning water than in the case where the water discharging holes are fixedly disposed.

According to the seventh aspect, by arranging the water discharge holes in the oscillating body, it is possible to obtain a high sensation of washing over a wide area with a smaller flow rate of the rinsing water than in the case where the water discharge holes are fixed.

According to the present invention, by using a water pump as a means for supplying the washing water, the output of the water pump is made variable so that the washing water can be discharged stably in accordance with the set flow rate.

According to the ninth aspect, by opening and closing the on-off valve, a constant flow valve, a pressure reducing valve, and the like can be combined to supply a stable flow of washing water.

According to the tenth aspect, since an air pump is used as the air mixing means, by making the output variable, it is possible to easily obtain washing water having a continuous or stepwise washing strength at a stable temperature. .

In the eleventh aspect, an air amount control valve capable of changing the flow area is provided in the middle of the flow path of the air mixed with the washing water. It is possible to easily obtain washing water having a stepwise washing strength at a stable temperature.

In the twelfth aspect, the washing water can be efficiently heated by disposing the washing water heating means upstream of the air mixing means.

In the thirteenth aspect, since the present invention is applied to a human body local cleaning device, it is possible to save water, and to perform local cleaning with excellent usability and high detergency, and to safely and comfortably remove delicate local parts and mucous membranes. It is possible to wash.

According to the fourteenth aspect, since the washing water jetting mechanism for anal washing and the washing water jetting mechanism for female local washing are provided, comfortable washing suitable for each use can be performed.

In the fifteenth aspect, since the present invention is applied to a shower apparatus, it is possible to save water and to perform shower cleaning with excellent usability and high detergency.

In the sixteenth aspect, since the present invention is applied to a face washing apparatus, it is possible to save water, to have a good feeling in use, and to have a high detergency, and to wash a delicate face safely and comfortably. It is.

In claim 17, since the present invention is applied to a device for washing eyes and mouth, it is possible to wash eyes and mouth which can save water, have excellent usability and have high detergency, and can provide delicate eyes and mouth. It is possible to wash the inside safely and comfortably.

In claim 18, since the present invention is applied to an apparatus for cleaning mucous membranes, it is possible to save water and to wash mucous membranes having an excellent usability and a high detergency, thereby making delicate mucous membranes safe and comfortable. It is possible to wash.
