Field of the Invention The present invention relates to a sanitary washing device for washing a local area after stool using hot water or the like. 2. Description of the Related Art FIG. 5 is a flow rate-pressure setting graph showing control characteristics of a flow rate injected from a cleaning nozzle of a conventional sanitary washing device. In the conventional example shown in FIG. 5, the setting of the washing water was such that the flow values Q 1 , Q 2 ... Q 5 shown on the horizontal axis. The flow values Q 1 , Q 2, ..., Q 5 are settings in which the flow rates are equally divided. In this conventional washing water setting, the sensation felt by a human at the time of collision with a jet substantially corresponds to the momentum of the jet, so that the intensity sensation of the jet is not equal. That is, the change in the jet flow is difficult to understand at the flow rates Q 1 and Q 2 , and the change in the jet flow is large at Q 4 and Q 5 . As described above, in the conventional washing water setting method, the operation feeling and the feeling that a person actually receives from the jet flow are unbalanced, and the use feeling is unsatisfactory. Problems to be Solved by the Invention The setting of the washing water of the sanitary washing device does not match the feeling of the jet expected by a human at the time of operation with the feeling when the part to be washed actually receives the jet. It tries to solve the problem of imbalance. Means for Solving the Problems The present invention, in order to solve the above problems, a cleaning nozzle, a pressurizing means for pressure-feeding the cleaning water to the cleaning nozzle, and a flow control means for controlling the pressurizing means The flow rate control unit is configured to control the pressurizing unit so that the momentum of water sent by the pressurizing unit and jetted from the washing nozzle changes at substantially the same magnification. Effect The perceived value at the time of collision of the jet flow is proportional to the momentum.
The momentum F is F = mv, where flow velocity v is mass m. Assuming that the flow rate Q, the injection port cross-sectional area S, and the fluid density ρ, m = ρQ and v = Q / S, respectively. Therefore, F = ρQ
2 / S, and the flow rate value is set such that ρQ 2 / S is at equal intervals. Embodiment An embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a sanitary washing device, which includes a washing device main body 2 and a heating toilet seat 3. Reference numeral 4 denotes a washing nozzle, and reference numeral 5 denotes a toilet. In FIG. 2, reference numeral 6 denotes a pressure feeding and pressurizing unit, 7 denotes a hot water heating unit, 8 denotes a cistern, 9 denotes a water inlet provided with a filter, and 10 denotes a cleaning water channel opening / closing solenoid valve. Reference numeral 11 denotes a flow rate control means comprising an operation unit, a microcomputer, and a circuit unit, which opens and closes the electromagnetic valve 10 and controls the motor speed of the pressure feeding and pressurizing means 6 to control the flow rate. FIG. 3 is a circuit diagram showing an embodiment of the flow control means 11.
Is a rectifier circuit for generating a motor voltage of the pressure feeding and pressurizing means 6,
Reference numerals 13 and 14 denote ON / OFF triacs of the electromagnetic valve 10 and the pressure feeding / pressurizing means 6, respectively. FIG. 4 is a jet flow characteristic graph of the cleaning nozzle 4, in which the horizontal axis indicates the flow rate Q and the vertical axis indicates the momentum F. Q 1, Q 2 ...... Q 5 is a flow rate set value, F 1, F 2 ...... F 5 shows the momentum corresponding thereto. An operation returning to the above configuration will be described. When the washing switch (not shown) of the operation unit is turned on, a signal is issued from the microcomputer, and the triacs 13 and 14 are energized.
As soon as the solenoid valve 10 is opened, the motor of the pressurizing and pressurizing means 6 is started. The water sucked from the cistern 8 is pressurized by the pressure-feeding pressurizing means 6 and heated by the hot water heating unit 7 and then jetted from the cleaning nozzle 4 to hit the portion to be cleaned and perform a cleaning action. Then, cleaning purposes, depending on the contamination of the cleaning unit, and operates the water setting button of the operation unit, the microcomputer calculates a voltage applied to the pumping pressure means 6, Q 1 of FIG. 4, Q 2 ...... Q The triac 14 is controlled so that a voltage corresponding to the flow rate corresponding to 5 is applied to the motor. That is, the microcomputer calculates the flow velocity v and the mass m from the flow rate Q set by the water amount setting button and the jetting area S of the washing nozzle, and feeds the water so that the momentum F of the jetting jet from the washing nozzle becomes F = mv. A signal for driving the pressurizing means 6 is sent to the triac 14, and a predetermined voltage is applied to the pressurizing and pressurizing means 6 by the operation of the triac 14 in accordance with the signal, and the pressurizing and pressurizing means 6 rotates at a rotation speed corresponding to this voltage. change. When the number of revolutions changes, the pump pressure of the pumping / pressurizing means 6 changes, and the set flow rates Q 1 , Q 2, ..., Q 5 are obtained. The flow rates Q 1 , Q 2 ... Q 5 are not equally spaced as shown in FIG.
The exercise amounts F 1 , F 2, ..., F 5 on the vertical axis of FIG. In this manner, the momentum substantially equal to the human body interval of the jet flow is set to the equally divided flow rate setting, and the change at the time of adjusting the jet flow can be accurately sensed. Effect of the invention The sanitary washing device adjusts the jet flow from the washing nozzle according to the purpose of washing, the degree of contamination, physical condition, etc., by adjusting the adjustment amount so that the momentum is equally divided,
The setting value matches the feeling of the ejected fluid. As a result, the selection of the adjustment set value can be smoothly performed, and the change when the set value is changed can be grasped intuitively and firmly, and the comfort during use can be improved.
