[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the hot water flush toilet seat device according to the present invention will be described with reference to FIGS.
[0009]
The hot water flush toilet seat device 10 includes a case 14 including a main body 14A fixed to the rear upper surface of the toilet 12 and a sleeve 14B extending forward from one end of the main body 14A. A first control mechanism 20 is disposed in the sleeve 14B of the case 14, and the first control mechanism 20 is heated by the second control mechanism 30, the solenoid valve 40, and the heater 52 in the main body 14 </ b> A of the case 14. A hot water tank 50 for storing hot water and a nozzle mechanism 60 are provided.
[0010]
The solenoid valve 40 disposed on one side inside the main body 14A of the case 14 is connected to a water supply source 70 via a hose 72 and to the hot water tank 50 via a hose 44, respectively. When the electromagnetic valve 40 is opened by the action of the mechanism 20, the hot water in the hot water tank 50 is supplied to the anal cleaning nozzle 62 (bidet nozzle 64) via the switching valve 66, and the anal cleaning nozzle 62 (bidet nozzle) is supplied. The washing nozzle 64) extends into the toilet bowl 12, and the warm water is sprayed from the anal washing nozzle 62 (bidet washing nozzle 64) to wash the user's anus (bidet), as is well known. Which nozzle is supplied with hot water depends on the operating position of the switching valve 66.
[0011]
The hot water tank 50 is arranged on the other side inside the main body 14 </ b> A of the case 14. Water in the hot water tank 50 is heated by the heater 52. The water temperature is constantly detected by the temperature sensor 54, and the temperature is sent to the CPU 32 of the second control mechanism 30 as a signal. When the water temperature reaches a predetermined value, the CPU 32 controls the energization of the heater 52 from the power source 90 by interrupting the triac 34, and always maintains the water temperature at the predetermined value.
[0012]
As described above, the hot water tank 50 is fluidly connected to the water supply source 70 via the hose 44, the solenoid valve 40, and the hose 72. One end of the hose 72 connecting the water supply source 70 and the electromagnetic valve 40 is connected to the water supply source 70, and the other end is connected to a water supply port 414 of the body 410 of the electromagnetic valve 40, as will be described later. 7, Fig. 8). The hose 72 serves as a water supply unit for the hot water tank 50.
[0013]
The hot water tank 50 is formed by welding the opening flange portions 50X and 50Y of the two portions 50A and 50B to each other, but is formed by the joint portion of the two portions 50A and 50B, that is, the mutually welded opening flange portions 50X and 50Y. The enclosed surface extends in the vertical direction. The advantages provided by such a configuration are as follows. That is, since the portion 50A (50B) constituting the hot water tank 50 is molded, when the entire opening flange portion 50X (50Y) is projected (a portion surrounded by the opening flange portion 50X (50Y) is projected from a right angle direction). In this case, the projected area becomes maximum at the opening flange portion 50X (50Y). Therefore, it is possible to minimize the dead space by changing the shape of the portion 50A (50B) in the contraction direction in accordance with the internal shape of the case 14 and the shape and arrangement of components housed inside the case 14. it can.
[0014]
As clearly shown in FIGS. 4 and 5, the case 14 is integrally formed with a land 14L. Further, a projection 50FP is formed integrally with a front portion 50A of the hot water tank 50, and the projection 50P is fixed by a screw 90. Before this fixing, positioning is performed by loosely fitting the projection 50RP projecting rearward from the rear portion 50B of the hot water tank 50 into the hole 14Q formed in the rear rib 14R of the case 14. You.
[0015]
As shown in FIG. 4, when the hot water tank 50 is positioned and fixed to the case 14, a gap G is defined between the hot water tank 50 and a rear portion 50B of the hot water tank 50. When water pressure is supplied into the hot water tank 50 via the valve mechanism 52, the hot water tank 50 expands. The expansion is filled in the gap G and received by the rear rib 14R of the case 14. . Then, when the water pressure supply is stopped, the hot water tank 50 returns to the original shape.
[0016]
As described above, since the hot water tank 50 has only one constraint point (does not have a plurality of constraint points), and also allows expansion and contraction when water pressure supply is started and stopped in the hot water tank, No local stress is generated at the constraint point, and the durability of the hot water tank 50 is ensured.
[0017]
As shown in FIGS. 6 and 7, the electromagnetic valve 40 includes a resin body 410. In this body 410, a passage 412 having an axis extending parallel to the main body 14A of the case 14 is formed. A water supply port 414 is formed in the body 410 and communicates with the passage 412 and is connected to the hose 72 to supply water pressure. A strainer 422 integral with the cap 420 is inserted into and removed from one opening of the passage 412. The strainer 422 crosses the axis of the water supply port 414. That is, the water pumped from the hose 72 to the water supply port 414 passes through the strainer 422 and reaches the operating section 430 on the other side of the passage 412. As the water passes through the strainer 422, foreign substances and the like are filtered. Thus, the operating section 430 is configured as a well-known electromagnetic valve mechanism, and establishes and blocks communication between the water supply port 414 and the hot water tank 50 via the strainer 422.
[0018]
The cap 420 integral with the strainer 422 seals the opening on one side of the passage 412 as the strainer 422 fits into the passage 412. The cap 420 protrudes slightly from the one side wall 14BL of the sleeve 14B of the case 14 to the outside. By operating the cap 420 from outside the sleeve 14B, the strainer 422 can be inserted into and removed from the passage 412. It can be done from outside. That is, the strainer 422 can be easily inserted into and removed from the passage 412 of the body 410 of the solenoid valve 40 from one opening of the passage 412 extending in the width direction of the toilet 2.
[0019]
The water supply port 414 of the body 410 of the solenoid valve 40 is connected to the hose 72 outside the sleeve 14B, which projects the base plate 14H of the case 14 vertically downward on the sleeve 14B side.
[0020]
As particularly clearly shown in FIGS. 4 and 7, the resin body 410 of the solenoid valve 40 includes a pair of stepped flanges 410A and 410B. Thus, the flange 410A is fixed to the land 14M protruding from the base plate 14H inside the case body 14A by the screw 499A. The flange 410B is located inside the case body 14A between the stepped portion 14S behind the case body 14A and the land 14N protruding from the base plate 14H. The screw 499B secures the flange 410B directly to the land 14N protruding from the base plate 14H, and the stepped portion 14S behind the main body 14A of the case to the land 14N indirectly via the flange 410B. Is done. As described above, by using the screw for fixing the main body portion 14A of the case to the base plate 14H together with the fixation of the solenoid valve 40 to the base plate 14H, it is possible to reduce the screwing locations and the number of work steps.
[0021]
As shown in FIG. 4, the hot water cleaning device 10 is provided with a hot air drying device 900. The hot air drying device 900 adheres hot air around the part to be cleaned after the hot water cleaning. The dried water drops are dried.
[0022]
The hot air drying device 900 will be described in detail with reference to FIG. The hot-air drying device 900 includes a duct 910 made of resin. The duct 910 includes a main body 912 disposed substantially parallel to the nozzle 62 and a root 914 integrally bent in the longitudinal direction of the case 14 from the rear of the main body 912. The root portion 914 is open, and a fan unit 920 is mounted on the open portion. The fan unit 920 includes a motor 922 and a fan 924 driven to rotate by the motor 922. The distal opening 916 of the main body 912 is aimed at the buttocks of the human body (near the anus, which is the part to be cleaned), and has a shutter 950 mounted thereon.
[0023]
Inside the main body 912 of the duct 910, a heater device 940 is provided. The space 910S defined by the rear surface of the heater device 940, the front portion of the fan 924, and the outer R portion 910R at the boundary between the main body portion 912 and the root portion 914 forms a fan shape in a horizontal cross section. Rectifying fins 960 are provided in the space 910S so as to be located between the fan 924 and the heater device 940. The curvature of this rectifying fin 960 is set to be substantially the same as the curvature of the outer R portion 910 </ b> R, and the space 910 </ b> S serving as a passage of the flow of the air supplied from the fan unit 920 to the heater device 940 is radially divided into two parts. Thus, the air flows into the heater device 940 at right angles without being disturbed.
[0024]
As is well known, the heater device 940 heats an internal heating element (not shown) to a predetermined temperature and warms surrounding air. This air is pushed out as warm air by the air supplied from the fan unit 920 to the heater device 940, pushes up the shutter 950, and is blown to the buttocks from the front end opening 916 to be used for drying the buttocks.
[0025]
Thus, a pair of rectifying fins 980 and 990 are provided immediately in front of the tip opening 916 so that the warm air blown out from the tip opening 916 reaches the buttocks reliably. In other words, the rectifying fins 980 are disposed so as to divide the distal end opening 916 in the left-right direction into approximately two equal parts and aim at the anus located at the center of the buttocks of the human body. The rectifying fin 980 is provided so as to further divide the right side of the distal end opening 916 defined by the rectifying fin 980 into approximately two equal parts and to aim at the anus located at the center of the buttocks of the human body. That is, the pair of rectifying fins 980 and 990 divide the tip opening 916 into a left part 916L, a center part 916C, and a right part 916R, and the opening area of the left part 916L is approximately equal to the center part 916C and the right part. It is twice as large as 916R. Further, the length of the rectifying fin 980 is substantially twice the length of the rectifying fin 990 in order to equalize the amount of hot air passing through the central portion 916C and the right portion 916R.
[0026]
A voltage is applied to the motor 922 and the heater device 940 of the fan unit 920 from a not-shown AC power supply via a two-wire cord 930 having a common bus.
[0027]
As described above, the embodiment of the present invention has been described, but the present invention is not intended to be limited to the above-described embodiment, and any warm water flush toilet seat device according to the gist of the present invention can be used. May be.
[0028]
【The invention's effect】
According to the first aspect of the present invention, there is provided a hot air drying apparatus in which the air heated by the heater device is blown out from the opening at the distal end of the duct toward the buttocks of the human body by the fan rotated by the motor. Since the rectifying fins are provided in the internal space of the duct so as to be located between the fan and the heater device, the rectifying fins can supply air from the fan to the heater device substantially concentrically. The hot air generated by the heater device is not disturbed. Thus, even if the fan and the heater device are not disposed coaxially, the turbulence and unevenness of the hot air discharged from the heater device are eliminated, and a great effect is obtained in practical use. The rectifying fins can also serve as a duct reinforcing member.
