DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for cleaning f'j from a hot water jet.

Dress up! As shown in Fig. 4, i/I' is <, /r<r6 water, and ■ is pressurized water from a pump, etc. f1! , supply pipe 211 (barrel, '+ l' +: magnetic) "22, rusting device rt
23. The Ik that entered the heating device 23 becomes two-part water and is ejected from the nozzle /l/24.

It hits the part to be cleaned and washes it off in γ′lj. jet flow jit
Is it possible to adjust the opening/closing degree of the valve manually using iri? The temperature is controlled by the method of feedback control of the heater input using a t-function sensor (t″ in the figure).

The problem that the invention aims to solve However, in F's FRr + 戊, in a typical household, 1
Continuous input 1 (has a control edge, water boiling 1:, the ability to i
There is d+sawakai. Therefore, when the inflow water/11A is low, it is necessary to control the flow and collapse to obtain a predetermined temperature. However, with a single manual flow adjustment, it is impossible to respond to the delicate human sense of temperature and response speed. As a result, the temperature during washing fluctuates, causing discomfort.

To solve the problem, supply means for T = stage cleaning), flow adjustment ``1 submergence, cleaning water trick [RT, temperature sensor 2fA to detect 2 types of cleaning water:
The cleaning nozzle and the judgment function are controlled by a control unit that controls the cleaning nozzle and the cleaning water temperature.

If the inflow water temperature is high and it is possible to raise the purified water temperature within the human power range of 7 Jll equipment y < 744, cleaning will be performed with the same amount of cleaning water and temperature. Next, the inflow water temperature decreases, and the forest tower necessary for heating becomes the rusting device.
If n is exceeded, the signal from the temperature sensor indicates that the washing water has reached the upper limit +rfE, and the flow rate adjustment means' control fJI is added by 1, 1, 11, . ．． 'I
Lower the setting fuT1 to below and set the washing water temperature to M.

Examples Below, examples of the sanitary cleaning device rt of the present invention are shown in Figures 1 to 3.
This will be explained based on the diagram.

In the device, 4 is a blackness sensor that detects the temperature of the washing water, and 5 is a washing nozzle, which is separated into two nozzles: 6 for ff1T bar washing and 7 for bidet. Reference numeral 8 is a sub-side part in which a microcomputer with a judgment function is assembled and controls the washing water flow f and the washing water temperature, 9 is a knob for adjusting the flow M, and 10 is a knob for setting the temperature. 11 (・1 sister>, 12

As a means of adjustment, I used a tilt on the rotating side of the motor once a month, but there is also a method of separately throwing one oLIr to control the flow f+ that narrows down the two flow paths. The water pumped from the pump 1 flows into the threshold type l crystal II processing device't 3 and is then transferred to the II gate cleaning nozzle 6.
The water is ejected from any of the bidet nozzles) L/7 (J44 plus) and hits the area to be cleaned for cleaning.

When the initial set value of 1υj is reached, the microcomputer circuit 19 built in the sub-side 1st section 8VC determines that the initial set flow rate of 1υj is maintained and cleaning is performed. Thereafter, the cleaning is completed by stopping the operation.

Next, the inflow water temperature decreases and increases! 1' Pass If the required transposition exceeds the Shonozukizawa limit of Kawakaku ffff3 ((ha.

When the temperature of the inflow water decreases, the rotation speed of the motor 2 increases to 1, and the amount of washing water becomes 1: below the minimum flow i1111α, -q icon l! ′! 'li (each 19 Vv ' between I place + f co, 1: S, wash r?t !II! I work is 1 hen I

According to the sanitary cleaning device of the present invention, the following effects can be achieved in May and November. 1) Become.

(1) Even if one item of inflow water drops and the hot oil required to heat the water exceeds the 7 Jll thermal capacity of the heating device, and the initial set temperature cannot be maintained, the microcomputer will automatically control the flow.
The 11 system sub-system is carried out, and C51: Purified water crystal is automatically held for comfortable washing.

(2) When the design 1c is designed to completely satisfy the flow 11 and temperature under the inflow conditions of low-temperature water, the disadvantage of increasing the heating capacity more than necessary is eliminated. Especially electric money!
When PIIH4- is used for I/J2, its capacity can be lowered, and the heating device including the control circuit can have a low system 1.
