Aspring 68a is connected to thehandle 68 to normally hold thehandle 68 in a first position where each of thepins 69 is maintained in the extended position. When thehandle 68 is rotated (for example, downward) against the biasing force of thespring 68a from the first position to a second position, the pins are retracted to permit the entrance of thestretcher 50 in the washing chamber. After thestretcher 50 has been placed in position within the washing chamber, thehandle 68 is released. Thus, thepins 69 are automatically moved to the extended position and are fitted into respective recesses (not shown) formed on the inside walls of the front and rear wall member, so that thestretcher 50 is prevented from displacing. By rotating thehandle 68 to the second position, thepins 69 are disengaged from the recesses to permit the exit of thestretcher 50 from the washing chamber. - The above-mentioned
feed tube 34 is connected to a warm water-supplyingdevice 25 as shown in Figs. 1 and 4. Afirst pump 27 is connected to a hot water source (boiler) 26 for increasing the pressure of hot water supplied thereto to a predetermined pressure of, for example, above 3.0 kg/cm2, while asecond pump 28 is connected to a water source for increasing the pressure of water supplied thereto to, for example, above 3 kg/cm2. Thepumps valves first pump 27 and the pressure of the water fed from thesecond pump 28, respectively, to a predetermined pressure of, for example, 2.5 kg/cm2. First and second flow switches 27a and 28a are interposed between thefirst pump 27 and thepressure controlling valve 29 and between thesecond pump 28 and thepressure controlling valve 30, respectively, and are operable to stoprespective pumps - Designated as 31 is a mixer connected to the

Thevalve 39 is connected to ahand shower 18 through a flexible hose extending out of thehousing member 2. - A
low temperature sensor 45 and a switchingvalve 46 are disposed in thefeed hose 40. Thesensor 45 is adapted for detecting the temperature of the warm water passing therethrough. When the temperature of the warm water detected by thesensor 45 is below a predetermined minimum value, for example 37°C, thevalve 46 electrically coupled to thesensor 45 is operated for switching the passage of the warm water fromfeed hose 40 to a discharge side. When the detected temperature is not lower than the minimum value, the switchingvalve 46 directs the warm water toward themain tube 47. Themain tube 47 is connected to the upper andlower feed pipes flexible tubes 49. - An automatic discharging
valve 48 of a spring-biased type is connected to themain tube 47 to release the warm water therefrom when the pressure therewithin is below a predetermined pressure. The automatic dischargingvalve 48 is closed by the pressure generated in themain tube 47 when the switchingvalve mechanism 35 is so shifted as to feed the warm water from thefeed hose 40 to themain tube 47, thereby permit the warm water to be injected through thenozzles main tube 47 is lowered to atmospheric pressure due to the close of themanual switching valve 36 or the shifting of the switchingvalve 46 to the discharge side, the automatic dischargingvalve 48 opens so that the warm water within themain tube 47,feed pipes flexible pipes 49 is discharged therefrom through a drain pipe, since thenozzles main tube 47 and theflexible pipes 49 is prevented during the non-operating stage, the liquid initially injected from thenozzles main tube 47 but is warm water freshly supplied through thefeed pipes - The operation of the above washing device will be described below with reference to Figs. 3 and 6. First, an assisting person (B) assists a user, such as a patient, (A) to lie on the
mat 65 of thestretcher 50 along the longitudinal direction thereof. In the case of the stretcher shown in Fig. 5, the assisting person can adjust the height of themat 65 by stepping thepedal 59. The assisting person (B) positions thestretcher 50 in parallel with thehousing 2 and then pushes the stretcher in the washing chamber in thehousing member 2. Theside openings 71 andfront opening 10 are then closed with theshutters 14 and the closure means 17, respectively. Thereafter, the assisting person (B) operates the operating panel to select thevalve mechanism 35 as desired. Thus, warm water mixed with a shampoo or a sterilizing liquid, if desired, is then injected downward and upward from the upper andlower nozzles window 15. Using thehand shower 18, the face and head of the patient (A) protruded from the closure means 17 are washed. - After washing has been completed, the valve mechanism is stopped and the
