Description

[Detailed Description of the Invention] The present invention mainly relates to a sanitary washer that cleans the anal area after defecation using warm water.

Generally, in this type of sanitary washer, a hot water pump in a water tank pumps hot water to a nozzle, and the hot water jetted out from the nozzle performs cleaning. The cold water that remained inside would gush out, causing significant discomfort to the user.

However, in the past, the discharge side of the pump and the nozzle were connected with a water supply hose, and the nozzle and the water storage tank were further connected with a return hose, and when the pump was driven with the nozzle valve closed, the pump By returning the cold water inside the pump to the water tank via the water supply hose, the inside of the nozzle, and the return hose, it prevents the cold water inside the pump from gushing out at the beginning of cleaning, eliminating discomfort. A cleaning device has been proposed (Japanese Utility Model Application Publication No. 57-64342). However, with this conventionally proposed structure, it is necessary to lead out two hoses from the washer body and connect them to the nozzle, so there is a risk of connecting the two hoses to the nozzle incorrectly during assembly. In addition, the nozzle itself has to have two connection ports and a switching passage with a valve, making the structure complicated.Furthermore, the nozzle must be operated while routing two hoses, making it difficult to operate. The result was a decrease in

The present invention has been developed in view of this point, and the embodiments of the present invention shown in the drawings will be described in detail below.

The lower end protrudes into the base 2 through the opening 10.

A switch board 49 is attached to the inside of the upper end of the upper cover 4 with screws 49a, and a cleaning switch 50 and a heat retention switch 5 are mounted on this switch board 49.
1 and an energizing lamp 52 are provided. The cleaning switch 50 is a slide type switch, and an operating knob 54 is fitted into the operating element through an operating port 53 of the upper cover 4, and the knob 54 is positioned on the upper surface of the upper cover 4. On the other hand, the heat retention switch 51 is a rotary type switch, and the operation knob 5 is connected to the operation knob 5 through the operation port 55 of the upper cover 4.
6 and position the knob 56 on the upper surface of the upper cover 4. Therefore, recesses 57 and 58 are formed on the upper surface of the upper cover 4 to suppress the amount of protrusion of the operation knobs 54 and 56. By opening the openings, water and other liquids are prevented from accumulating in the recesses 57 and 58. On the other hand, water walls 59 and 60 are protruded from the periphery of each operation port 53 and 55 to prevent liquid from entering the upper cover 4. Prevents the inflow of water, etc. Note that waterproof sheets 61 and 62 are attached to each of the operation knobs 54 and 56 to cover the operation ports 53 and 55. Further, a through hole is formed in the upper surface of the upper cover 4 to correspond to the energizing lamp 52, and a lamp cover 63 is attached to the through hole.

The switch board 49 has both ends bent downward to form inner pieces 64, 64, and these guide pieces 64,
64 to the inner surface of the upper cover 4,
This one guide piece 64 is extended to near the lower end of the upper cover 4, and a knob portion 65 is bent at the tip. Therefore, even at the deepest part of the upper end of the upper cover 4 whose width is narrowed due to the formation of the storage space 45, the cleaning switch 50 and the heat retention switch 51 can be easily aligned with the operation ports 53 and 55. Assembly workability can be significantly improved.

The cartridge type tank 5 has a handle 6 on the top opening.
6 is attached and also includes a removable cover plate 67,
A water supply port 68 is formed at the bottom of the water supply port 68 so as to protrude downward. A seal gasket 70 is clamped and supported between the water supply port 68 and a gasket presser 69 attached thereto, and the tank 5 is placed on the washer body 1.
When the part is fitted into the socket 43, both are kept in a watertight state. Further, the seal retainer 69 supports a valve shaft 72 having a valve body 71 at its upper end so as to be movable up and down. This valve shaft 72 is always biased by a spring 73 to keep the water supply port 68 closed by the valve body 71, and when the tank 5 is placed, it is pushed up against the spring 73 by the valve shaft abutting portion 44, thereby supplying water. Mouth 6
Open 8.

The tank 5 has a semicircular cross section, and its outer circumferential arc surface coincides with the outer circumferential surface of the base 2. or,
The tank 5 has a valve shaft 72 connected to the lower end of the outer circumferential arc surface.
A skirt portion 74 that protrudes downward from the lower end is integrally formed, and this skirt portion 74 allows the tank 5 to be
When the unit is placed on the floor, the valve shaft 72 is prevented from being pushed up by the floor.

When such a tank 5 is placed on the cleaning device main body 1, the water inside the tank 5 is supplied into the water tank 11 through the water supply port 68 and the socket 43, and the water inside the tank 5 is
Normally, the water level in the lower end of the socket 43, that is, the water supply port 68
It will rise to the lower end position and will not rise any further. This is because there is no escape route for the air in the water tank 11, and the upper part of the water tank 11 is filled with air. Therefore, the amount of water stored is small compared to the volume of the water tank 11, and the volume of the water tank 11 cannot be used effectively. However, in this embodiment, the ventilation pipe 72 of the base cover 3 is provided upright to provide an escape route for the air in the water tank 11, so that water can be stored in the entire water tank 11. That is, water tank 1
By fully utilizing the volume of 1, it is possible to store a large amount of water even in a small volume. The vent cylinder 75 is located inside the upper cover 4, and its upper end is located above the specified water level of the tank 5.

Although the water tank 11 becomes full of water, the O-ring 42 and seal packing 70 prevent the base cover 3
There will be no flooding on top. However, in consideration of the worst case, in this embodiment, the base cover 3 and the water tank 1 are
Water walls 76 and 77 are provided protrudingly on the peripheral edge of the base 1 to prevent water from entering the inside of the base 2 from the opening 10.

The nozzle 6 is equipped with a flow rate adjustment valve 78,
Flexible hose 7 wound so that it is always in a contracted state
9. Pump 27 via joint 80 and hose 81
It is connected to the discharge port 35 of. The flexible hose 79 is introduced into the base 2 through the hose storage tube 47 and is stored in the hose storage tube 47 in a contracted state. Further, the joint 80 is a T-shaped joint, which connects the flexible hose 79 and the hose 81 in a straight line, and connects the branched end perpendicular thereto to the inner bottom of the water tank 11 via the hose 82. .

In the figure, 83 indicates a power plug, and 84 indicates a power cord.

The sanitary washer of the present invention has the above-mentioned structure, and its electric circuit is formed as shown in FIG. The cleaning switch 50 is selectively switched to the contact a side when the operating knob 54 is set to the "ON" display, and to the contact B side when the operating knob 54 is set to the "OFF" display. In addition, the heat retention switch 51 switches the open contact c side when the operation knob 56 is set to the "Water" display, the contact d side when the control knob 56 is set to the "warm retention 1" display, and the contact e side to the contact e side when the operation knob 56 is set to the "warm retention 2" display. They are selectively switched.

Next, its effect will be explained.

First, I will explain the preparation stage. When the tank 5 is removed from the washer body 1 and filled with water, and the tank 5 is placed again in a predetermined position on the washer body 1, the valve body 71 is pushed up by the valve shaft 72 being pushed up against the spring 73. Open the water supply port 68. Therefore, the water in the tank 5 flows from the water supply port 68 through the socket 43 into the water tank 11, and when the water level in the water tank 11 reaches the specified water level, the reed switch 2 is activated.
0 is ON, that is, the water level switch 17 is in the ON state. Since the water level in the water tank 11 has an air escape route called the ventilation pipe 75, the water level in the water tank 11 rises further than the specified water level, and the water tank 11 becomes full of water.

Therefore, the sanitary washer is kept energized at all times. Now, when the power plug 83 is connected to an AC power source, the energization lamp 52 lights up to indicate the energization state. At this time, the user switches the heat retention switch 51 to an arbitrary position. Let's assume that the user selects hot water with a high temperature and sets the operation knob 56 to "warm retention 2". Heater 15
is the contact point b of the cleaning switch 50 in the "off" position,
Electricity is applied through the contact e of the heat retention switch 51 and the thermal reed switch 21 to heat the water in the water storage tank 11 and raise it to the operating temperature of the thermal reed switch 21. From then on, the electricity is applied intermittently by turning the thermal reed switch 21 ON and OFF. kept at a constant temperature. Therefore, hot water at a desired temperature is stored in the water tank 11 and is ready for use.

Note that the nozzle 6 is housed in a nozzle storage cylinder 48,
Since it is covered by the lid 46, it can be stored hygienically, and the lid 46 prevents the warm air inside from escaping to the outside when the room temperature drops below zero, especially at night in winter. Water remaining inside the flexible hose 79 etc. will not freeze.

Therefore, when using it after defecating, press the operation knob 5.
4 to switch the cleaning switch 50 to the contact a side.
The pump 27 is driven by turning on the heater 15, cutting off the power supply to the heater 15, and supplying power to the motor 28 via the transformer 37 and the rectifier 38. Then, the hot water in the water tank 11 is circulated through the pump chamber 31, the hose 81, the joint 80 and the hose 82,
While the temperature is made uniform by stirring by this circulation, the cold water remaining inside the pump chamber 31 and the like is returned to the water storage tank 11 and heated. In this state, if the nozzle 6 is taken out and the flow rate adjustment valve 78 is operated to open the flow path, the hot water in the water tank 11 is force-fed from the flexible hose 79 to the nozzle 6 and is vigorously jetted out, causing the anal region It will be used for cleaning. At the beginning of use, cold water is ejected from the nozzle 6, but only a small amount of water remains in the nozzle 6 and the flexible hose 79, and does not cause any particular discomfort to the user. Further, a portion of the hot water is circulated through the hose 82 into the water storage tank 11 to continue stirring.

After use, if the cleaning switch 50 is turned on by operating the operating knob 54 and the contact b side is turned on, the pump 27 is stopped, while the heater 15 is energized again, and as the water level in the water tank 11 decreases, the water level in the tank 5 decreases. By heating the newly supplied water, hot water at the desired temperature is stored again and prepared for next use.

In the above embodiment, if the tank 5 is used in an empty state and the water level in the water storage tank 11 drops to the level at which the water level switch 17 operates to shut off the power, the reed switch 20 will turn OFF, and the power shut off will also occur. The water level is set at the upper end of the water suction cylinder 14, that is, at the pump 2.
Since it is set slightly above the suction side opening portion of No. 7, it is possible to stop the pump 27 before it becomes idling. Also, in this state, turn the cleaning switch 50
Even if the contact b side is turned on and left unattended, the heater 15
is not energized by turning off the reed switch 20, which prevents the dangerous situation of dry firing.

As described above, according to the configuration of the present invention, it is possible to eliminate the discomfort caused by the spout of cold water inside the pump with an extremely simple configuration using a T-shaped joint, and also to connect it to the nozzle by drawing it out from the washer body. Because only one hose can be used to connect the hose, there is no need to make mistakes in connecting the hoses during assembly, and the structure of the nozzle itself can be simplified, and the operability of the nozzle is improved compared to when two hoses are routed. This is an excellent idea in practical terms.
