I feel better.

The functions of the present invention basically comprise the automatic processing mode shown in FIGS.
The points improved or changed by the present invention are as follows.
(1) Separation of defecation, urination and air by the defecation separation unit 111 When the defecation and urination of the diaper cup 110 are sucked into the defecation separation unit defecation separation unit 111 together with the washing water by the suction motor 154, the defecation introduction cover 119 Solids and moisture collide with the collision plate 128 and fall into the defecation tank 118. At the same time, the air containing water that has been sucked up rises from the air discharge port 129 and is removed when passing through the filter 135 in units of microns, and only the air travels around the partition plate 134 and is discharged from the air discharge port 136. . The water separated by the filter 135 flows down the upper surface 132 and falls from the air discharge port 129 to the defecation tank 118. In this way, only air is separated from defecation, urination and moisture and sent to the deodorizing unit 112.

(2) Improvement or Change of Hot Water Unit 115 The heat retaining tank 173 is disposed directly below the washing water supply tank 175. When the washing water supply tank 175 is placed on the outer box 174 integrated with the heat retaining tank 173, the valve 180 is opened by the protrusion 177, and when the water is full, the lower end surface of the cap-equipped cap 179 is covered with the water in the heat retaining tank 173. Closed. When the water in the heat retaining tank 173 is exhausted, the valve 180 is open, so that it is dropped and replenished by its own weight. When the water in the washing water supply tank 175 is exhausted, the level sensor 184 detects a decrease in the water level in the heat retaining tank 173 and notifies the display unit 207 and the buzzer 215.

The washing water sent out from the washing pump 186 is sent out to the diaper cup 110 through the check valve 182 and the safety tank 188. The check valve 182 is used in place of the conventional cleaning valve 46 shown in FIG. 11, thereby enabling cost reduction and space saving. A temperature sensor 185 is provided in the heat retaining tank 173 to monitor the temperature. In this heat retaining tank 173, the cleaning water heated by the heater 183 is only naturally convected, and the entire temperature is constant. Since the temperature is not limited, the temperature sensor 189 is provided in the safety tank 188 so that the temperature immediately before the cleaning water sprayed on the diaper cup 110 is monitored again so that the temperature becomes an appropriate temperature (for example, 38 to 40 ° C.). I have control. In addition, the safety tank 188 is provided with an excessive temperature detection switch 190 so that when the washing water temperature rises excessively (for example, 46 ° C.), the apparatus is stopped by turning off the power, and the like. This is notified by the display unit 207 or the buzzer 215.
The cleaning pump 186 is provided with a pump operating current sensor 219 to detect an operating current flowing through the cleaning pump 186. When the operating current exceeds a set value, the cleaning water hose 139 is bent, a diaper cup and a diaper cup. The display unit 207 is notified of an overload state such as a clogging of the injection nozzle in 110.

(3) Connection of Defecation Tank Outer Box 199 and Main Body Side Outer Box 201 The main body side outer box 201 was fixedly attached to the carriage 116, and the defecation tank outer box 199 was detachably attached to the carriage 116. Therefore, the electric power supplied from the control panel 203 on the main body side outer box 201 side intervenes an isolator 211 such as electromagnetic induction and photo coupling as shown in FIG. The creepage distance and the spatial distance are greatly increased and wirelessly combined. As a result, power is prevented from flowing directly from the control panel 203 or the like to the diaper cup 110, thereby improving safety.

(4) Improvement of the cooling unit 114 The work wind flowing between the diaper cup 110 and the excrement disposal apparatus is heated by the suction unit 113 as it circulates repeatedly. The cooling fan 170 is attached to the radiator 169 so that the work air discharged from the suction unit 113 does not exceed 50 ° C., the outside air from the cooling fan 170 is introduced, cooled, and discharged to the atmosphere.
In addition, the air passage and the light air passage between the main body side outer box 201 and the defecation tank outer box 199 are coupled with each other via the joint box 192. Thereby, connection with the main body side exterior box 201 and the defecation tank exterior box 199 can be performed reliably and simply. The air temperature is monitored by the air temperature sensor 217 in the joint box 192, the excessive temperature rise is detected by the excessive temperature detection switch 218, the apparatus is stopped by turning off the power, and the display. This is notified by the unit 207 and the buzzer 215.

(5) Improvement of Breeze Channel When the breezes channel is sucked by the breezes pump 152 as shown by the dotted line in FIG. 7, the sterilization filter 193, the joint box 192, the radiator 169, the suction fin portion 155, and the filter container are drawn from the diaper cup 110. It is discharged to the atmosphere through a light wind channel consisting of 144. The fine wind pump 152 can perform suction efficiently by using a pump that can increase the suction pressure. Since this fine wind passage uses the same work wind passage in the opposite direction, the check valve 194 and the check valve 147 do not flow except for the fine wind passage.

(6) Improvement of the deodorizing unit 112 By providing a filter replacement lid 145 in the filter container 144 of the deodorizing unit 112, the deodorizing filter 146 can be easily replaced. Moreover, it sterilizes by installing the ultraviolet light emitter 151. Further, even if sterilized by the deodorizing unit 112, there is a possibility that various germs may adhere in the flow path to the diaper cup 110. Therefore, the germs are removed by providing a sterilization filter 193 immediately before the diaper cup 110 is blown.
The diaper cup 110 is worn on the human body using a diaper, but may be loose or tight depending on individual differences of caregivers. If it is tightly attached, the outside air will not flow into the diaper cup 110, and the suction pressure may increase and the excrement disposal apparatus may stop. Therefore, a negative pressure sensor 150 is provided in the filter container 144 to monitor whether or not it is properly attached from the negative pressure value. If it becomes larger than the set value, it is displayed on the display unit 207 so that the excrement disposal apparatus is properly worn before it stops.
