  1 and 2 show a Western-style toilet 1 having a toilet seat 3 with a cleaning function, which is an example of an embodiment of the present invention. The toilet seat 3 with a cleaning function is used in place of the toilet seat 21 of the conventional Western-style toilet 20 provided with the sanitary cleaning device 2, and is installed at the bottom of the toilet seat 3a and the toilet seat 3a that is rotatably connected to the main body 8. It consists of a wide area cleaning unit 4. Although the main body 8 is different from the conventional main body 22 in that a device that guarantees the function of the toilet seat 3 with the cleaning function of the present invention is incorporated, the device that drives the conventional sanitary washing device 2 is similar to the conventional Western toilet 20. I have.

  The wide area cleaning unit 4 includes left and right nozzles 5 and 6, a slide mechanism (not shown) for inserting and removing the left and right nozzles into the bowl 7a of the toilet bowl 7, and a water supply means for supplying cleaning water for the shower 4a to the left and right nozzles ( (Not shown).

  The left and right nozzles 5 and 6 are provided with a plurality of ejection holes 5a and 6a for showering water 4a upward in a substantially L-shaped plane at the bottom and rear of the toilet seat 3a. The left and right nozzles 5 and 6 are arranged along the shape of the facing toilet seat. And it is installed in the bowl 7a of the toilet bowl 7 so that a slide is possible.

  In FIG. 2, the state after the left and right nozzles 5 and 6 slide in the direction of the bowl 7a is indicated by dotted lines. Holes 5a and 6a are located in the opening 3d. When spraying the shower 4a from the left and right nozzles 5 and 6, it is preferable because the cleaning efficiency is increased by swinging the left and right nozzles 5 and 6 in the sliding direction.

  The holes 5a and 6a may be provided not only on the upper surfaces of the left and right nozzles but also on the side surfaces. Further, the side surfaces of the left and right nozzles inside the bowl 7a may be formed in a trapezoidal shape with a long bottom in the cross section, and the holes 5a and 6a may be provided in the side surfaces. The positions of the holes 5a and 6a are appropriately changed in consideration of the shape of the toilet seat 3a so that a suitable injection direction can be obtained.

  As shown in FIG. 2, the front end portions 5d and 6d of the toilet 7 of the left and right nozzles 5 and 6 are preferably located at a substantially central portion in the front-rear direction of the toilet seat 3a. The buttock can be washed extensively and sufficiently, and the thigh can be prevented from being unnecessarily wetted by the shower 4a.

  For example, as shown in FIG. 2, the slide mechanism of the left and right nozzles 5 and 6 is lanes 5c and 6c for guiding the slide direction, and the left and right nozzles 5 and 6 slidably attached to the rails 5c and 6c are inserted and removed by motor drive. To do. The motor may be stored in the main body 8 or the toilet seat 3a. Further, the sliding mechanism of the left and right nozzles 5 and 6 is not limited as long as the right and left nozzles can be inserted and removed without dropping.

  As shown in FIG. 2, the water supply means to the left and right nozzles 5 and 6 supplies cleaning water to the left and right nozzles 5 and 6 through water channels 5b and 6b such as tubes, and showers from the ejection holes 5a and 6a. 4a is ejected. As a water source, you may acquire from the supply water path | route to the conventional local flushing means 2a, or you may acquire from a tap water and the tank 11 separately. Regarding the water pump, a water pump for the local water washing means 2a may be used, or a dedicated pump for jetting the shower 4a from the left and right nozzles 5 and 6 may be separately installed in the main body 8. Moreover, it is preferable that the temperature of the shower 4a is controlled by a heat exchanger in the main body 8 as in the conventional shower 2b.

  For example, the water source of the shower 4a is obtained after branching from the place where the heat exchanger also passes after the water pump of the local flushing means 2a, so that the temperature adjustment water by the water pump and the heat exchanger of the local flushing means 2a is adjusted. If it uses, the water supply means to the right-and-left nozzles 5 and 6 can be added to the toilet seat 21 of the conventional Western-style toilet 20 simply and compactly.

  When the shower 4a is ejected from the left and right nozzles 5 and 6, it is preferable to control the water supply pump so as to increase or decrease the ejection pressure of the shower 4a because the buttock cleaning effect is enhanced.

  The driving of the wide area washing unit 4, that is, the slide control of the left and right nozzles 5 and 6 and the drive control of the shower 4 a are performed by the wide area washing switch 9 a of the operation unit 9 provided continuously with the main body 8. Separately, a wide-area cleaning switch for driving the wide-area cleaning unit 4 may be provided on the wall 13. The power is supplied from a commercial power outlet 8d as in the prior art.

  Since the toilet seat 3 has the left and right nozzles 5 and 6 disposed on the bottom surface, the buffer member 3b needs to be disposed at a position that does not interfere with the arrangement of the left and right nozzles and the slide. Moreover, in order to allow the left and right nozzles 5 and 6 to slide, that is, when the user sits on the toilet seat 3a, a certain height is secured so that the left and right nozzles 5 and 6 are not pressed against the upper end surface of the toilet bowl 7 by the toilet seat 3a. There is a need to.

  The toilet seat 3 is further provided at the bottom of the toilet seat 3a in order to prevent the shower 4a from seeping out from between the toilet seat 3a and the toilet bowl 7 from the front end portions 5d and 6d when the left and right nozzles 5 and 6 are stored. A stopper 3c may be provided.

  The stopper 3c may be the same height and the same material as the buffer member 3b. Moreover, it is better to form the part which contacts the toilet bowl 7 upper end with the material which has cushioning property and has much better adhesiveness than the buffer member 3b. For example, rubber etc. can be illustrated. Further, in consideration of replacement due to dirt, it may be detachably fixed to the toilet seat 3a with a screw 3e or the like.

First, the cared person 12 is seated on the toilet seat 3a of the toilet seat 3 with the cleaning function. At this time, by closing both thighs 12b, leakage and ejection of the shower 4a from the thighs 12b can be suppressed.

  After confirming that the seating and thigh 12 have been closed, the caregiver presses the wide-area washing switch 9 a for starting the wide-area washing section 4 of the operation section 9. Then, the left and right nozzles 5 and 6 slide toward the opening 3d of the toilet seat 3a by the rotational drive of the motor housed in the main body 8, and stop at the dotted line position in FIG. At that time, the holes 5a and 6a are located inside the toilet seat 3a. Further, when the left and right nozzles 5 and 6 are desired to be pushed out, if the rear end portions of the toilet bowls 7 of the left and right nozzles 5 and 6 are in contact with each other, the upper end of the toilet bowl 7 and the toilet seat 3a behind the toilet bowl 7 of the shower 4a. Leakage from between can be prevented.

  After the left and right nozzles 5 and 6 are slid and pushed out and stopped, the shower 4a (broken arrows in FIGS. 3 to 5) is ejected toward the collar 12a. Thereby, as shown in FIG. 5, the wide range (gray part) of the collar part 12a can be lined up.

  After sufficiently cleaning the collar part 12a, the caregiver presses the wide area washing switch 9a of the operation part 9 to finish the injection of the shower 4a, and the left and right nozzles 5 and 6 are placed on the bottom part of the original toilet seat 3a. Stored. Note that the spraying time of the shower 4a may be controlled by a timer.

  After the cleaning of the heel part 12a by the shower 4a is completed, the caregiver presses a switch that activates the drying means of the operation unit 9. Thereby, the attached water droplet of the shower 4a is blown off by the drying means 2c equipped in the western style toilet 20 conventionally, and the collar part 12a is air-dried. Moreover, it is good also as a structure which sprays a warm air from the ejection hole 6a of the shower 4a toward a collar part, blows off a water droplet with a wind pressure, and dries. In this case, even if the air of the conventional drying means is introduced, it may be configured to have a separate hot air fan system. Alternatively, the water droplets after washing may be blown off by the wind pressure from the ejection hole 6a of the shower 4a and then dried using conventional drying means.

  When a large amount of water droplets remain, the caregiver may put his hands in the gap between the thighs 12b of the care recipient 12 and wipe the water droplets with a towel or the like. Then, the cared person can stand up and the caregiver can wipe off the water. Such a work can be performed in a simpler and shorter time than a conventional bath shower and towel wiping, and the burden on both the caregiver and the cared person is greatly reduced.
