BACKGROUND OF THE INVENTION
The present invention relates to a cleaning device used when cleaning a human body part.
[0002]
[Prior art]
The human body cleaning apparatus cleans the human body part with warm water after stool. The operation principle of the conventional human body local cleaning apparatus will be described with reference to FIGS.
The tap water (cold water) branched from the main water pipe is drawn into the human body local cleaning device 1 by opening and closing the water shut-off valve 2 disposed in the main body casing 5, and the hot water tank (washing water heating means) 3 It heats and it ejects toward the human body part from the washing nozzle 4 to wash the human body part.
Here, as the washing water heating means, a sheathed heater 6 is installed in the casing of the hot water tank 3, and a hot water storage type that heats and keeps cold water, and an instantaneous type that does not wait for a heat keeping function that instantaneously heats inflowing cold water. There is.
The hot water storage type has a problem that a large amount of electric power necessary for heat insulation is required to store the wash water and maintain the temperature of the water.
[0003]
[Problems to be solved by the invention]
In addition, the instantaneous cleaning device that avoids power consumption due to heat retention by heating the cleaning water only during cleaning increases the flow path to ensure contact (heat transfer) time with the heater. There was a need to do. Here, a long flow path can be formed by using a ceramic heater whose shape can be freely changed. However, when an inexpensive sheathed heater is used, there is a limitation on the bending curvature (R), and a free shape is taken. I could not.
[0004]
In addition, in order to provide an economical cleaning device, when a sheathed heater is used, the length of the sheathed heater and the hot water tank casing is approximately the same as the full width of the main body casing (300 to 300 mm) so as to secure the flow path length without bending. 500 mm), during heating, stress was applied to the fixing portion between the casing and the sheathed heater due to the difference between the thermal expansion of the sheathed heater and the thermal expansion of the hot water tank casing.
In addition, the main body casing is fixed to the toilet bowl with two mounting bolts, but the casing is deformed by the undulation of the main body casing mounting surface of the toilet bowl, and among the built-in parts, parts that are fixed across both sides of the mounting bolt, for example, The inconvenience which affects the case which accommodates a straight tubular sheathed heater and a heater generate | occur | produced.
[0005]
Therefore, in the present invention, the problems to be solved are the stress applied to the fixed portion due to the difference in thermal expansion between the straight tubular sheathed heater and the straight tubular case during heating, and the straight tubular seeds due to the deformation of the main casing. This is to prevent the heater and the pipe-like case from being deformed.
[0006]
[Means for Solving the Problems]
The human body local cleaning device of the present invention includes a cleaning nozzle that ejects water, a water shut-off valve that branches from the water main and supplies the cleaning water to the cleaning nozzle, a straight pipe-shaped case, and a pipe-shaped case And a washing water heating means for heating the washing water is housed in the main body casing.
The sheathed heater in the washing water heating means has one end fixed to the pipe-shaped case and the other end held in the pipe-shaped case so as to be slidable in the central direction of the sheathed heater. The structure which comprises packing at both end portions of the is provided.
The straight pipe-shaped case of the washing water heating means has a configuration in which one end is fixed to the main body casing and the other end is slidably held in the central axis direction of the pipe-shaped case.
Furthermore, the straight pipe-like case of the washing water heating means has a configuration in which one end is fixed to the main body casing and the other end is slidably held in the vertical direction.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a toilet bowl with a human body local cleaning device, and FIG. 2 is a schematic explanatory diagram of the configuration of the human body local cleaning device.
The toilet bowl 10 with the human body local washing device has an operation unit 12 disposed beside the toilet seat 11 and heats water introduced from the water main 15 by an operation button of the operation unit 12 by a heating unit (not shown). However, it is configured to eject from the cleaning nozzle 21.
[0008]
In the human body local cleaning device 20, a water shut-off valve 23, a cleaning water heating device 25, and a cleaning nozzle 21 are connected to pipes 22 a and 22 b and are disposed in a main body casing 29.
The water shut-off valve 23 is in a water path from the water main 15 to the cleaning nozzle 21 and is configured to be able to selectively open and close the water path selectively by an electromagnetic valve or the like.
When washing is instructed by the operation button, the washing nozzle 21 moves the spout 210 from the standby position to the washing position and ejects water. When the operation button is instructed to stop, the washing nozzle 21 stops the ejection of water from the washing position. It is configured to be stored in the standby position. The nozzle 210 is moved by a water pressure expansion / contraction type nozzle that is moved by the pressure of the washing water or a motor expansion / contraction nozzle that is moved by an electric drive means (motor).
[0009]
Next, the configuration of the cleaning water heating apparatus will be described with reference to FIG.
The washing water heater 25 includes a straight tubular sheathed heater 250 and a pipe-shaped case 260 that accommodates the heater 250.
The pipe-like case 260 has a water inlet 261 communicating with the water shutoff valve 23 at one end, and a water outlet 263 communicating with the cleaning nozzle 21 at the other end. A water flow path 30 is formed between the straight tubular sheathed heater 250 to be accommodated.
[0010]
The seed heater 250 and the pipe-like case 260 hold nectar by loading packing 40 at both ends in the longitudinal direction. The sheathed heater 250 and the pipe-shaped case 260 are fixed on the water inlet 261 side. In this fixing, the sheathed heater 250 has a flange 251 at the edge, and is fixed by a stopper 50 so that the flange 265 of the pipe-like case 260 is matched. The packing 40 is attached to the flange 251 of the sheathed heater 250 to seal between the pipe-shaped case 260.
[0011]
The edge of the pipe-shaped case 260 on the water outlet 263 side is sealed with a bush 253 disposed on the edge of the sheathed heater 250 and a packing 40 attached to the bush 253.
The pipe-shaped case 260 has a fixing flange 267 protruding at a position close to the water inlet 261. The fixing flange 267 is fixed to a boss 291 protruding from the main casing 29 with a screw 50 (see FIG. 4). Further, the other end of the pipe-shaped case 260 is sandwiched and held by a holding rib 293 protruding from the main body casing 29 as shown in FIG.
[0012]
In the washing water heating apparatus 25 configured as described above, when washing is selected, the sheathed heater 250 is heated by energization to heat the water in the flow channel 30 flowing in from the inflow port 261. At this time, the sheathed heater 250 extends in the longitudinal direction (the central axis direction of the sheathed heater 250) due to thermal expansion. The sheath heater 250 is fixed to the pipe-shaped case 260 on the water inlet 261 side, but the bush 253 on which the packing 40 is mounted is fitted to the pipe-shaped case 260 on the water outlet 263 side so that it is a free end. A bushing 253 attached to the end of the sheathed heater 250 slides inside the case 260 and corresponds to the expansion due to thermal expansion.
In this way, stress due to thermal expansion of the sheathed heater 250 is not applied to the fixing portion with the pipe-shaped case 260.
[0013]
Further, the pipe-like case 260 expands with the temperature rise of water. However, one end of the pipe-shaped case 260 is fixed to the boss 291 of the main casing 29, but the other end is only held by the holding rib 293 of the main casing 29 and is a free end. It is possible, and no stress is applied to the fixed portion due to the difference in thermal expansion during heating.
Moreover, although the human body local washing | cleaning apparatus 20 is mounted in the toilet bowl 10, when there exists a wave | undulation etc. in the mounting surface, the main body casing 29 will deform | transform. However, one end of the pipe-shaped case 260 is guided by the holding rib 293 with respect to the main body casing 29 and is held so as to be movable in the vertical direction (perpendicular to the central axis of the case). Moves and absorbs strain, and the tube device does not deform.
[0014]
FIG. 6 shows another example of the holding rib of the main body casing 29.
The holding rib 293 has a claw portion 295 protruding inward at the tip.
With this configuration, even if the pipe-like case 260 held by the holding rib 293 moves in the vertical direction, the pipe-like case 260 is regulated by the claw portion 295 and does not fall off from the holding rib.
[0015]
FIG. 7 shows another configuration of the fixing portion between the pipe-shaped case 260 and the sheathed heater 250.
The fixing portion is configured such that the flange 251 of the sheathed heater 250 and the flange portion 265 of the pipe-like case 260 are sandwiched by fixing ribs 297 protruding from the main body casing 29 and the upper portion is locked by the claw portion 295. Yes.
This configuration does not require a fastener such as a screw and can reduce assembly man-hours.
