F _A is the non-stick straight jets, F _B represents a wall attachment oscillating flow.

The operation will be described in the above configuration. In the case where the dirt is severe or the washing is to be washed off with a strong washing feeling in the anal washing, a straight jet motion instruction is given by the operation unit 10a. In response to this instruction, the control means 44 operates, and the pump as the washing water supply means 16 starts. In this case, the forward / reverse rotation drive motor 28 of the blower 29 that drives the diaphragm pump 21 is stopped. As a result, the washing water passes through the hot water tank 17 and the switching valve
Based on the setting of 18, it is sent to the anal cleaning nozzle 19 and is sprayed toward the surface to be cleaned. In this operating state, since the diaphragm pump 21 is not driven, the nozzle 50
Since the jet in the not containing air bubbles, jet from the cleaning nozzle will be washed jets i.e., straight jet, such shows the linearity as shown in Figure 4 F _A. As a result, the cleaning is performed intensively in a narrow area, and the strength is high.

Next, in the case of relatively light dirt or a wide range of dirt in the cleaning anus, the operation unit 10a instructs the oscillating jet motion of the gas-liquid mixed phase. In response to this instruction, the control means 44 operates to start the pump which is the washing water supply means 16, and the forward / reverse rotation drive motor 28 of the blower 29 starts to rotate, and the gas is actuated by the action of the one-way clutch 27 which is the power transmission means 27. The diaphragm pump serving as the supply means 21 is in a motion state. The washing water passes through the hot water tank 17 as described above, and is sent to the anal washing nozzle 19 based on the setting of the switching valve 18 and is jetted toward the part to be washed, but the air sent from the gas supply means 21 is introduced into the washing water.

As a result, the cleaning is performed over a large area, giving a soft feeling.

When the washing section is dried after washing, the operation section 10
Instruct a dry exercise in a. According to this instruction, drying means 26
The forward / reverse rotation drive motor 28 for driving the blower 29 starts rotating forward and rotates the blowing blade 30 in the blowing direction. The blown air is heated by the drying heater 33 in the blowing passage 32, and becomes hot air to dry the surface to be cleaned. In this case, since the forward / reverse rotation drive motor 28 rotates forward, the power transmission means 27 does not rotate due to the action of the one-way clutch, and therefore, the gas supply means
21 does not work.

As described above, according to the cleaning apparatus of the embodiment of the present invention, the forward / reverse rotation of the forward / reverse rotation driving motor 28 of the drying unit 26 causes the power transmission unit 27 to transmit power or cut off the transmission to supply gas. Since the gas supply and stop of the means 21 can be controlled, the cleaning jet can be formed into two types, a DC jet and an oscillating jet, and the cleaning of the portion to be cleaned is strong and weak, and the optimum cleaning can be performed according to the range. The size and cost of the cleaning device can be reduced.
