[0002]
[Prior art]
In recent years, with the advent of the elderly, the nursing of bedridden elderly people at home has become a major social problem. In this care, the excrement is particularly difficult to process.
[0003]
In recent years, various portable toilets that can be placed like furniture in a room such as a hospital room have become commercially available. In this portable toilet, a toilet bowl upper edge is arranged in a portion corresponding to a seat portion of a chair, a container storage chamber is provided below the toilet bowl, and a portable container-like container is arranged in the container storage chamber. . The excrement of the care recipient falls into this container. This container is taken out from the container storage room by a caregiver in a timely manner and processed in a toilet room or the like.
[0004]
In recent years, portable portable toilets that incorporate a warm water washing device for washing the buttocks with warm water have come to be marketed. By using this warm water cleaning device, it is possible to clean the heel part and to obtain the merit that the filth accumulated in the container is covered with water and odor emission is prevented.
[0005]
[Problems to be solved by the invention]
A portable toilet incorporating a hot water cleaning device has a large amount of water stored in the container as much as the hot water cleaning device is used, and there is a risk that filth will overflow from the container. In addition, if the user forgets to stop the hot water washing apparatus, the filth may overflow from the container.
[0006]
An object of this invention is to prevent the overflow from the container resulting from use of such a warm water washing apparatus.
[0007]
[Means for Solving the Problems]
The portable toilet of the present invention spouts hot water so as to wash the toilet bowl, the container into which the excrement from the toilet bowl is introduced, the container storage chamber containing the container, and the buttocks of the toilet user with warm water. In a portable toilet having a hot water cleaning device, the means for measuring the amount of hot water jetted from the hot water cleaning device and the hot water jetting restricted when the integrated value of the hot water jetting amount measured by the measuring means reaches a predetermined value And a control means.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. FIG. 1A is a cross-sectional view of a portable toilet according to an embodiment, FIG. 1B is a block diagram thereof, and FIG. 2 is a flowchart showing control contents.
[0011]
A toilet 14 is installed on a box-like gantry 12 having legs 10. The upper edge of the toilet 14 is locked to the upper surface of the gantry 12, and the rest of the toilet bowl 14 is disposed in the gantry 12 except for the upper edge. An inner space is a container housing chamber 16 on a gantry below the toilet 14, and a container 18 is disposed. The container 18 is open at the top, and is adapted to receive fallen objects from the toilet bowl 14 therein.
[0012]
A stopper 20 is provided in the back of the container housing chamber 16, and a reed switch 22 is provided on the stopper 20. A magnet 24 is provided on the back side of the container 18 so as to face the reed switch 22. A door 26 is provided in the lower front portion of the gantry 12 so that the container 18 can be taken in and out by opening the door 26. A handle 18 a is provided on the front surface of the container 18.
[0013]
A toilet seat box 30 is installed on the rear upper surface of the gantry 12, and a toilet seat 32 is connected to the toilet seat box 30 so as to be rotatable in the up-down direction.
[0014]
The toilet seat box 30 includes a shower nozzle 34 for washing the buttocks of a human body seated on the toilet seat with warm water, a hot water tank 36 for supplying warm water to the shower nozzle 34, a pump 38, and the pump 38. A control circuit 40 and the like are installed.
[0015]
In addition to the cleaning switch 42, the cleaning strength adjusting switch 44, and the cleaning stop stop switch 46 provided on the remote control (not shown) of the remote control or the toilet seat box 30, the reed switch 22 A signal is input from. Although not shown, the hot water tank 36 is provided with a heater and a temperature sensor, and energization of the heater is controlled so that the detected water temperature of the temperature sensor becomes a set temperature. Further, the remote controller or the overhanging portion is provided with a switch for adjusting the set temperature, and the control circuit 40 is also provided with an energization control portion for the heater.
[0016]
The shower nozzle 34 has a cylinder 34a and a nozzle body 34b protruding from the cylinder 34a. When warm water is supplied into the cylinder 34a, the nozzle main body 34b moves forward, the warm water is spouted upward from its tip, and the human buttock is washed with warm water.
[0017]
In this embodiment, the amount of hot water ejected per unit time (washing strength) from the shower nozzle nozzle 34 is adjusted by adjusting the rotation speed of the pump 38. Further, the hot water ejection amount (integrated value) is calculated by integrating the rotation speed of the pump 38.
[0018]
An operation example of the portable toilet configured as described above will be described with reference to FIG.
[0019]
Zero is stored as an initial value in the ejection amount integrated value memory of the control circuit 40.
[0020]
If the container 18 is inserted deeply into the container housing chamber 16 until the reed switch 22 is turned on, the process proceeds from step 1 to step 4 and waits until the cleaning switch 42 is operated. When the washing switch 42 is operated, the process proceeds from step 4 to step 5 to activate the pump 38 and integrate the ejection amount (steps 6 to 7). If the stop switch 46 is operated before the integrated value of the ejection amount reaches the set amount A, the process proceeds from step 7 to step 8, the pump 38 is stopped, and the process returns to step 1. The set amount A is smaller than the capacity of the container 18. Also in step 6, when the integrated value of the ejection amount reaches the set amount A before the stop switch 46 is operated, the process proceeds from step 6 to step 8, the pump 38 is stopped, and the process returns to step 1.
[0021]
If the second use is made without taking out the container 18 after returning to Step 1, the same procedure as described above is repeated. In this case, the warm water ejection amount integrated value is added to the first ejection amount, and when the total ejection amount (integrated value) reaches the set amount A, the pump 38 is stopped. The same applies when a use other than the third is subsequently performed.
[0022]
If the container 18 is taken out while the pump 38 is in a stopped state, the reed switch 22 is turned off, so the process proceeds from step 1 to step 2 and waits until the reed switch 22 is turned on. Then, when the container 18 is mounted and the reed switch 22 is turned on, the process proceeds from step 2 to step 3, the ejection amount integrated value memory is reset to zero, and then the process proceeds to step 4. The subsequent procedure is the same as above.
[0023]
Thus, according to this embodiment, since the warm water washing water does not accumulate in the container 18 more than the set amount A, the overflow from the container 18 due to the use of the warm water washing apparatus is prevented.
[0024]
In the above embodiment, the hot water ejection amount is calculated from the integrated value of the rotation speed of the pump 38, but the hot water ejection amount may be measured using a flow meter.
[0025]
In the above embodiment, the gantry 12 and the toilet seat box 30 are separate bodies, but both may be integrally formed with a synthetic resin. A deodorizing device may be provided in the gantry 12. In addition, a sensor for detecting the total weight of the container 18 may be provided so that the hot water ejection is stopped when the total weight of the contents of the container 18 exceeds a set amount.
[0026]
【The invention's effect】
As described above, according to the present invention, in a portable toilet equipped with a hot water cleaning device, overflow from the container due to the operation of the hot water cleaning device can be prevented.
