<2> Configuration of Hot Water Tank FIG. 3 is a perspective view showing the appearance of the hot water tank, FIG. 4 is a perspective view showing a state in the middle of attaching the hot water tank to the main body, and FIG. 5 is a state with the hot water tank attached. A sectional view is shown.

  As shown in FIG. 3, the tank body 510 of the hot water tank 500 is formed integrally by welding an upper member 511 and a lower member 512, which are molded from a resin material that is made by adding glass fiber to ABS resin to increase its strength. .

A water supply port 513 through which cleaning water flows is provided in the lower front part of the side surface of the tank body 510, and a water supply port 514 through which cleaning water is supplied is provided in the upper rear part. A vacuum breaker 520 for introducing air from the outside when the pressure in the tank becomes negative is installed on the upper surface of the tank body 510.

  A U-shaped sheathed heater 530 is installed as a heating means for heating the wash water at a position near the bottom surface 515 at the lower part of the hot water tank 500, and as a temperature detecting means for detecting the hot water temperature near the sheathed heater 530. A thermistor (not shown) is installed.

  Further, a drain valve 540 capable of discharging all the water in the tank is installed at the lowest position of the bottom surface 515 of the tank body 510, and the drain valve 540 is directed obliquely downward from the front of the tank body 510. It is installed. The drain valve 540 is used for preventing freezing in a cold region or discharging polluted water when not used for a long time.

  As shown in FIG. 4, a rectifying means 550 is provided inside the water supply port 513 of the tank body 510 so as to make the flow of the wash water that has flown uniform. The rectifying means 550 is configured to change the cross-sectional area of the flow path and the flow direction by combining the rectifying ribs 516 formed on the bottom surface 515 of the tank body 510 and the rectifying member 551.

  By providing the rectifying means 550 having the above-described configuration, the cleaning water flowing in from the water supply port 513 has a uniform flow, and is sent out below the sheathed heater 530 along the bottom surface 515.

  As shown in FIG. 5, a plurality of internal reinforcing ribs 517 are provided in the lateral direction on the rear inner surface of the lower member 512 of the tank body 510. A plurality of external reinforcing ribs 518 are also provided outside the bottom surface 515 of the lower member 512, and the pressure resistance strength of the tank body 510 is increased by these internal reinforcing ribs 517 and the external reinforcing ribs 518.

  Although it is feared that the surface of the tank body 510 is increased by providing the ribs on the tank body 510 and the heat of the stored cleaning water is easily radiated, the internal reinforcing ribs 517 provided at the rear portion of the tank body 510 have a tank. Since it is installed on the inner surface of the main body 510, there is almost no influence on heat dissipation, and the external reinforcing rib 518 disposed on the outside of the bottom surface 515 has some influence on heat dissipation, but the washing water stored at the bottom of the hot water tank 500 is Can be kept to a minimum due to the longer period of time at which the temperature is lower than the wash water stored in the upper part.

  A joining surface that joins the upper member 511 and the lower member 512 of the tank main body 510 has a substantially diagonal line shape between a rear upper portion and a front lower portion of the tank main body 510. Further, a reinforcing edge reinforcing edge projecting outward is provided on the outer periphery of the opening edge of the upper member 511 and the opening edge of the lower member 512, which are joint portions, to reinforce the pressure strength of the side surface of the tank body 510. In particular, the length of the reinforcing edge can be maximized by making the joint surface diagonal, which greatly contributes to reinforcement.

  The outer surface of the tank body 510 is provided with a heat insulating material 560 on all surfaces. The heat insulating material 560 is a two-layer sheet shape in which an aluminum sheet is bonded to the surface of foamed urethane, has a thickness of about 3 mm, and is placed with the urethane foam side in close contact with the outer surface of the tank body 510.

  As shown in FIG. 4, the top surface, front surface, back surface, and both side surfaces of the tank main body 510 are attached with a heat insulating material 560 in a single state of the hot water tank 500. The heat insulating material 560 used for these parts is a foamed urethane surface coated with an adhesive, and is adhesively fixed to the surface of the tank body 510 via the adhesive.

On the other hand, the heat insulating material 560 to be installed on the bottom surface 515 is difficult to attach using an adhesive because the external reinforcing ribs 518 are disposed on the bottom surface 515, and the bottom surface of the hot water tank 500 is washed at a low temperature. Since water and heated hot water are supplied alternately, the temperature difference is large and the strength of the pressure-sensitive adhesive tends to decrease in a short time, so that pressure-sensitive adhesive fixing with pressure-sensitive adhesive is not suitable.

  In the present embodiment, as shown in FIG. 4, a heat insulating material 560 having substantially the same shape as the bottom surface 515 of the tank main body 510 is temporarily placed at a predetermined position on the bottom plate 260 of the main body 200 and preliminarily placed on a surface other than the bottom surface 515 from above. The hot water tank 500 to which the heat insulating material 560 is adhesively fixed is installed, and the hot water tank 500 is fixed to the bottom plate 260 via screws (not shown), so that the heat insulating material 560 is attached to the hot water tank 500 and the bottom plate 260 of the main body 200. It is configured to be held and fixed.

  FIG. 5 is a sectional view showing a state in which the hot water tank 500 is attached to the bottom plate 260. The heat insulating material 560 disposed below the bottom surface 515 of the hot water tank 500 includes the upper surface of the bottom plate 260 of the main body 200 and the tank main body. 510 is sandwiched between external reinforcing ribs 518 formed with a bottom surface 515 of 510.

  As described above, in the sanitary washing device in the present embodiment, all the outer surfaces of the hot water tank are covered with the heat insulating material, and a high heat insulating effect can be obtained. In particular, it is possible to stably maintain the installation state without being affected by temperature changes by sandwiching the heat insulating material placed on the bottom surface of the hot water tank between the bottom surface of the hot water tank and the bottom plate of the main body. A stable heat insulating effect can be obtained.

  In addition, the hot water tank of the present embodiment is provided with a rectifying means in the vicinity of the water supply port, thereby diffusing low temperature wash water supplied from the water supply port along the bottom surface, thereby increasing the temperature inside the hot water tank. Since changes can be concentrated on the bottom, by suppressing temperature changes on the front, back, both sides, and top surface other than the bottom surface, the adhesive strength of the heat insulating material attached to those surfaces can be maintained over a long period of time. It can be maintained stably.

  As described above, since the sanitary washing device according to the present invention can maintain the installation strength of the heat insulating material installed in the hot water tank for a long period of time, it can be used for other heat appliances and the like having a large temperature change. Is also applicable.
