Description

  Aspects of the present invention generally relate to a toilet apparatus, and more specifically, to a toilet apparatus that can wash a user's “butt” or the like sitting on a Western-style toilet bowl with water.

  The initial local cleaning equipment was not equipped with a hot-air drying function or deodorizing function, so the parts such as the cleaning nozzle, instantaneous heat exchanger, and control board were placed inside the functional casing. (For example, see Patent Document 1).

  On the other hand, as the local cleaning apparatus has been recognized by the world, additional functions such as a hot air drying function and a deodorizing function have been gradually added. At present, many functional components such as a cleaning nozzle, a hot air drying device, a deodorizing device, and a control board are arranged inside the casing (see, for example, Patent Document 2). Therefore, the casing is larger than the initial local cleaning device. The increase in the size of the casing leads to a reduction in the product function of the local cleaning device. An example of this is a decrease in comfort in the toilet seat.

This is due to the fact that the hinge position of the toilet seat becomes higher than that of the initial local cleaning device due to the increase in size of the casing. That is, the rear part of the seat surface of the toilet seat rises obliquely upward, and the rear part of the buttocks of the person sitting on the toilet seat comes into contact with the inclined part. The contact of foreign matter at the back of the buttock causes a sloppy sensation, and in the case of a heated toilet seat with a heater inside the toilet seat, it causes a cold sensation, which causes a decrease in sitting comfort on the toilet seat. ing.

Similarly, the toilet lid 400 is automatically opened and closed using a toilet lid electric opening / closing unit described later according to the detection status of the human body detection sensor 202A and the human body detection sensor 202B or the operation of a switch (not shown) by the user. be able to.

FIG. 3 is a schematic side view for explaining the hot air drying apparatus of the present embodiment.
FIG. 4 is a schematic cross-sectional view showing the inside of the casing in a state where the cleaning nozzle is housed. That is, FIG. 4 corresponds to the AA cross-sectional view in FIG. In the toilet apparatus shown in FIG. 3, the cleaning nozzle is stored in the notch 102 of the toilet 100.

  Inside the casing 200, there is provided a warm air drying device that blows hot air toward a “buttock” of a user sitting on the toilet seat 300 to dry it. The hot air drying device includes a hot air duct 500 for guiding the hot air into the bowl 104 of the toilet 100, a hot air blowing fan 504, and a heater 506. The hot air blowing fan 504 is disposed in the rear part inside the casing 200. Note that most of the hot air blowing fan 504 is disposed below the upper surface of the toilet 100. The hot air duct 500 has a jet outlet 502 at one end on the bowl 104 side, and the other end communicates with the hot air blowing fan 504. Further, the hot air duct 500 has a bent portion 512 bent upward between the hot air blowing fan 504 and the jet port 502. The heater 506 is provided in the hot air duct 500 between the bent portion 512 and the end portion on the side communicating with the hot air blowing fan 504. Note that, as will be described in detail later, the entire warm air blowing fan 504 may be disposed below the upper surface of the toilet 100.

  The hot air duct 500 further includes a hot air damper 508 that closes the ejection port 502, and the hot air damper 508 is pivotally supported by the hot air duct 500 so as to be openable and closable around an opening / closing shaft 510. Note that the hot air damper 508 illustrated in FIG. 4 represents an open state. The hot air damper 508 may be opened by opening / closing means (not shown), or may be opened by the wind pressure of the warm air sent from the hot air blowing fan 504 through the inside of the hot air duct 500. The warm air sent from the warm air blower fan 504 through the heater 506 is directed from the outlet 502 toward the user's “buttock” or the like with the warm air damper 508 opened as shown in FIG. Be sprayed.

  A cleaning nozzle unit is further provided inside the casing 200. The cleaning nozzle unit has a cleaning nozzle 520 that moves into the bowl 104 of the toilet 100 by a driving force transmitted from a nozzle motor (not shown), and a nozzle cleaning that cleans the outer peripheral surface of the cleaning nozzle 520 in a state where the cleaning nozzle 520 is housed. A chamber 522 and a cylinder portion 526 that houses at least a part of the cleaning nozzle 520 are provided.

  The cleaning nozzle 520 is provided slidably with respect to the cylinder portion 526 and the nozzle cleaning chamber 522, and at least a part of the cleaning nozzle 520 can be accommodated in the cylinder portion 526. In the state in which the cleaning nozzle 520 is stored, as shown in FIG. 4, the cleaning nozzle tip 524 is disposed inside the notch 102 of the toilet 100 and stored in the nozzle cleaning chamber 522. Most of the parts other than the cleaning nozzle tip 524 are accommodated in the cylinder part 526. At this time, the cleaning nozzle 520 is in a state of being inclined forward and downward.

  Therefore, as shown in FIG. 4, the jet port 502 of the hot air duct 500 is disposed closer to the front side (closer to the bowl 104) than the cleaning nozzle 520 in the housed state. That is, the jet outlet 502 of the hot air duct 500 is not disposed directly above the cleaning nozzle 520 or the nozzle cleaning chamber 522 in the housed state. Therefore, the height of the casing 200 in the vertical direction can be kept low. Thereby, the sitting comfort when the user sits on the toilet seat 300 becomes better.

  This is because the height of the casing 200 can be kept low, whereby the height of the opening / closing shaft 210 of the toilet seat 300 can be kept low, that is, the height of the rising portion 304 at the rear portion of the toilet seat 300 can be kept low. This is because it can. The toilet seat 300 includes a flat portion 302 that extends from the front end portion to the rear portion, and a rising portion 304 that is gently inclined at the rear portion. And in order to stabilize the posture when the user is sitting on the toilet seat 300, the user tries to place the buttocks behind the toilet seat 300. Therefore, if the flat part 302 is extended long to the back part and the height of the rising part 304 is further lowered, the sitting comfort on the toilet seat 300 becomes better. This is because the foreign object does not contact the rear part of the buttocks, so that the user does not feel terrible or feels cold when the toilet seat is a heated toilet seat.

  In the toilet apparatus according to the present embodiment, as described above, the height of the casing 200 can be kept low by disposing the spout 502 closer to the front than the cleaning nozzle 520 in the housed state. The sitting comfort when the user sits on the toilet seat 300 becomes better. Moreover, since the jet nozzle 502 is disposed at a substantially central portion with respect to the left-right direction of the casing 200 and close to the bowl 104, the jet nozzle 502 can be brought close to the user's buttocks. Therefore, drying efficiency such as “wet” can be further increased.

FIG. 5 is a schematic side view for explaining the deodorizing apparatus of the present embodiment.
FIG. 6 is a schematic cross-sectional view showing the inside of the casing in a state where the cleaning nozzle has advanced. That is, FIG. 6 corresponds to the AA cross-sectional view in FIG. In the toilet apparatus shown in FIG. 5 as well, the cleaning nozzle represents a state where it has advanced into the bowl.

  Inside the casing 200 is provided a deodorizing device that sucks air in the bowl 104 to remove odor components. The deodorizing device includes a deodorizing blower fan 534 that sucks air in the bowl 104, a deodorizing duct 530 for guiding the air in the bowl 104 to the deodorizing blower fan 534, and an odor component from the air discharged from the deodorizing blower fan 534. And a deodorizing catalyst 536 to be removed. As will be described in detail later, the deodorization duct 530 has a suction port near one end on the bowl 104 side, and the other end communicates with a deodorization blower fan 534. Further, half or more of the deodorizing blower fan 534 is disposed below the upper surface of the toilet 100. Furthermore, the entire deodorizing catalyst 536 disposed below the deodorizing blower fan 534 is disposed below the upper surface of the toilet 100. In addition, as will be described in detail later, the entire deodorizing blower fan 534 may be disposed below the upper surface of the toilet 100.

  The air in the bowl 104 is sucked from the suction port of the deodorizing duct 530 and is sucked into the deodorizing blower fan 534 through the deodorizing duct 530. Subsequently, the air sucked into the deodorizing blower fan 534 is blown out toward the deodorizing catalyst 536 and passes through the deodorizing catalyst 536. By doing so, the odor component of the air in the bowl 104 is removed.

  The cleaning nozzle 520 illustrated in FIG. 6 represents a state where the cleaning nozzle 520 has advanced into the bowl 104. At this time, it is more preferable that the warm air damper 508 is closed. This is because the water discharged from the cleaning nozzle 520 may be rebounded by the user's “wet” or the like, and the water may be applied to the heater 506 disposed in the hot air duct 500. If water is applied to the heater 506, the heater 506 may be damaged. Therefore, it is more preferable that the hot air damper 508 is closed when the cleaning nozzle 520 has advanced into the bowl 104.

  Further, the hot air duct 500 has a bent portion 512 bent upward, and the heater 506 includes the bent portion 512 and a hot air blowing fan 504 communicated with an end portion on the opposite side to the jet port 502. Even if water or small water enters from the jet port 502, the water or small water gets over the bent portion 512 bent upward and is applied to the heater 506. There is little fear.

FIG. 7 is a schematic enlarged view in which a part of the inside of the casing of the present embodiment is enlarged and viewed.
Moreover, FIG. 8 is the schematic diagram which looked at a part inside the casing of this embodiment from front diagonally.
FIG. 9 is a schematic top view of a part of the inside of the casing according to this embodiment as viewed from above.
In the toilet apparatus shown in FIGS. 7 to 9, the cleaning nozzle 520 represents the state of having advanced into the bowl 104.

  As shown in FIG. 7 to FIG. 9, the hot air duct 500 passes through the hot air blowing fan 504 to the side of the cylinder portion 526 of the cleaning nozzle unit, that is, to the side of the cleaning nozzle 520 in the housed state. Through the upper side of the nozzle 520, it extends further forward (closer to the bowl 104) than the cleaning nozzle 520 in the housed state. Therefore, as described above with reference to FIG. 4, the ejection port 502 is provided closer to the front than the cleaning nozzle 520 in the housed state. The hot air duct 500 is a wind direction rib that adjusts the air direction in the vicinity of the jet port 502 in order to blow the hot air sent from the hot air blowing fan 504 toward the user's buttocks more reliably. You may have.

  On the other hand, as shown in FIGS. 7 to 9, the deodorizing duct 530 passes through the side of the hot air duct 500 from the deodorizing blower fan 534 (see FIG. 5) and is a suction port provided near one end on the bowl 104 side. 532 is placed in the bowl 104. At this time, the suction port 532 is spaced apart from the side of the jet port 502 of the hot air duct 500. That is, the jet port 502 and the suction port 532 are not superposed in the vertical direction. For this reason, the warm air duct 500 and the deodorizing duct 530 are not superposed in the vertical direction in the vicinity of the suction port 532.

  As a result, the height of the casing 200 in the vertical direction can be kept low. Thereby, as described above with reference to FIG. 4, the sitting comfort when the user sits on the toilet seat 300 becomes better. Further, with respect to other effects, the same effects as those described above with reference to FIG. 4 can be obtained.

Furthermore, a toilet seat electric opening / closing unit 310 for automatically opening and closing the toilet seat 300 is provided at the right front portion in the casing 200.

  As shown in FIG. 11, a deodorizing blower fan 534 that sucks air in the bowl 104 is provided below the casing 200 and on the right side of the toilet 100. A controller board 560 is provided below the deodorizing blower fan 534. The controller board 560 determines the operation of the cleaning nozzle unit, the hot air drying device, the deodorizing device, etc. based on the operation of the switch (not shown) by the user or the detection status of the human body detection sensor 202A, the human body detection sensor 202B, the seating sensor 206, etc. Can be controlled.

  As described above, the human body detection sensor 202A and the seating sensor 206 are provided on the upper surface of the casing 200. A hot air blower fan 504 is disposed below the casing 200 and below the upper surface of the toilet 100. A hot air duct 500 is provided in front of the hot air blowing fan 504. As described above with reference to FIGS. 7 to 9, the hot air duct 500 passes through the side of the cylinder portion 526 and is stored. It is arranged over the front side of the cleaning nozzle 520.

  A cleaning nozzle unit is provided at the center front portion in the casing 200. As described above with reference to FIGS. 1 and 2, the cleaning nozzle unit advances the cleaning nozzle 520 into the bowl 104 from the notch 102 of the toilet 100 and supplies water from the water outlet 528 provided near the tip of the cleaning nozzle 520. The user can sit on the toilet seat 300 to wash the “butt” and the like.

  In the toilet apparatus according to the present embodiment, the whole or part of the hot air blowing fan 504 of the hot air drying apparatus and / or the whole or part of the deodorizing catalyst 536 and the deodorizing fan 534 of the deodorizing apparatus are used as a casing. It can be disposed below 200 and below the upper surface of the toilet 100, that is, at a site hidden by the side panel 150. As a result, the casing 200 can be made into a small size, and the height can be kept low from the front part to the rear part of the casing 200, and the upper surface of the casing 200 has a flat shape with little unevenness. be able to. Therefore, a toilet device with high design can be realized.

  FIG. 12 is a block diagram illustrating a water channel system for explaining the tank of the present embodiment. The water supply valve unit 552 has a strainer, a constant flow valve, and an electromagnetic valve, and is connected to a water supply source such as a water supply or a water storage tank. The strainer is a filter having a mesh structure, for example, and removes foreign matters mixed in the water supply. A tank 556 is provided on the downstream side of the water supply valve unit 552. The tank 556 is provided with an overflow port. Further, on the downstream side of the tank 556, a pump unit 554, a heat exchange unit 550, a vacuum breaker, a flow control / switching valve, a cleaning nozzle 520, and the like are provided.

  Here, when the user operates a switch (not shown), the toilet apparatus of the present embodiment opens the electromagnetic valve of the water supply valve unit 552 and further drives the pump unit 554 to be provided near the tip of the cleaning nozzle 520. Water is jetted from the discharged water outlet 528. At this time, the water that has passed through the water supply valve unit 552 is temporarily stored in the tank 556. Since the tank 556 has an overflow port, when the water level in the tank 556 rises above a predetermined water level, water flows out from the overflow port to the water channel connected to the bowl 104. In this way, it is possible to prevent water from flowing backward from the pump unit 554 to the water supply valve unit 552.

  As described above, according to the present embodiment, the jet port 502 of the hot air duct 500 is disposed closer to the front (closer to the bowl 104) than the cleaning nozzle 520 in the housed state.
