Description

  The present invention relates to a heating toilet seat device and a toilet device, and more specifically to a heating toilet seat device that heats a toilet seat with warm air and a toilet device including the same.

  If the toilet seat of the flush toilet can be heated, the toilet can be used comfortably even in winter when the temperature is low. As a means for heating the toilet seat, there is a method of circulating hot air (Patent Document 1). When the hot air is circulated, the toilet seat can be efficiently heated with less heater power while suppressing exhaust heat.

By the way, if warm air is blown and dried on the user's “tail” sitting on the toilet seat or the user's body is warmed, a more comfortable and comfortable heating toilet seat device can be realized. However, in many cases, the temperature and air volume of the warm air for heating the toilet seat are not necessarily the same as the temperature and air volume of the hot air blown out toward the user. Therefore, when switching the air path of the warm air, control is required so as not to give the user unpleasant feeling.

  ADVANTAGE OF THE INVENTION According to this invention, the heating toilet seat apparatus which enabled control which does not give a user a discomfort at the time of switching of an air path, and a toilet apparatus provided with the same can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic perspective view of a toilet apparatus provided with a heating toilet seat apparatus according to an embodiment of the present invention.

  The heating toilet seat device of this specific example includes a casing 500 provided on the upper part of the flush toilet 300. The washing mechanism of the flush toilet 300 may be a so-called “low tank type” or a “water direct pressure type” that does not use a low tank.

  A toilet seat 410 and a toilet lid 400 are pivotally supported on the casing 500 so as to be freely opened and closed. The toilet seat 410 and the toilet lid 400 can be opened and closed manually, and can be automatically opened and closed by an electric opening and closing mechanism. In the present embodiment, the hot air supply means 550 is provided in the casing 500, and the toilet seat 410 can be heated by introducing the hot air into the toilet seat 410.

  Furthermore, the casing 500 may be provided with a functional unit as a sanitary washing device. In other words, the heating toilet seat apparatus appropriately includes a cleaning function unit having a water discharge nozzle 615 that ejects water toward a “butt” of a user sitting on the toilet seat 410. In the present specification, “water” includes not only cold water but also heated hot water. And the heating toilet seat apparatus of this example is provided with the warm air drying function which blows and dries warm air toward the "buttock" etc. of the user who sat on the toilet seat. Furthermore, it has a deodorizing function for sucking air in the bowl of the toilet bowl and reducing odor components through a filter, a catalyst, etc., and an indoor heating function for heating the toilet room by blowing hot air into the toilet room. be able to. These operations may be operable by a remote controller 200 provided separately from the casing 500, for example. However, in the present invention, the water discharge nozzle 615 and other additional functional parts are not necessarily provided, and the hot air heating mechanism of the toilet seat 410 and the functional part for ejecting hot air toward the human body such as the hot air drying function. As long as it is provided.

FIG. 2 is a conceptual diagram illustrating the toilet seat heating mechanism of the present embodiment. 2 and the subsequent drawings, the same elements and steps as those described in the previous drawings are denoted by the same reference numerals, and detailed description thereof is omitted as appropriate.
In the casing 500, for example, a fan 552 and a heater 554 are provided as the hot air supply means 550. The air sent from the fan 552 is heated by the heater 554 to generate hot air, and this hot air is introduced into the toilet seat 410 via the sending unit 560. A toilet seat internal air passage 412 as a warm air passage is formed in the toilet seat 410, and the warm air introduced from the sending section 560 into the toilet seat internal air passage 412 is contained in the toilet seat 410. , And returns to the hot air supply means 550 of the casing 500 through the return portion 570. That is, the toilet seat heating mechanism of this specific example forms a circulation path of the warm air supply means 550, the delivery section 560, the air flow path 412 in the toilet seat, the return section 570, and the warm air supply means 550, and the warm air passes through this circulation path. It is made to flow repeatedly. If it does in this way, exhaust air will be suppressed and warm air heating excellent in thermal efficiency will be attained. The operation of the warm air heating mechanism can be controlled by the remote controller 200, for example. That is, the temperature of the toilet seat 410 can be displayed on the remote controller 200 or the temperature can be set.

  In the delivery section 560, a hot air outlet is provided on the casing 500 side, and an inlet corresponding to the outlet is provided on the toilet seat 410 side. The return part 570 can also be provided with a warm air outlet on the toilet seat 410 side and an inlet corresponding to the outlet on the casing 500 side. As will be described later with reference to FIG. 4, the reversing unit 570 may be adjacent to the sending unit 560.

  As described above, in this specific example, warm air can be introduced into the toilet seat 410 to enable heating. According to this specific example, when the toilet seat 410 is removed from the casing 500 and cleaned or washed with water, it can be easily removed and remounted. However, the present invention is not limited to this specific example, and can be similarly applied to heating toilet seat devices having various structures as long as warm air is introduced into the toilet seat 410 and heated.

In the present embodiment, it is possible to switch from the toilet seat heating operation to the operation for blowing out the warm air toward the human body by switching the warm air path.
FIG. 3 is a schematic diagram for explaining switching of the air path of the warm air.

  The casing 500 is provided with a suction port 580 for taking in outside air and a discharge port 582 for discharging air. Openable and closable dampers (second opening / closing portions) 546 and 548 are provided in the air passages communicating with the suction port 580 and the discharge port 582, respectively. In the middle of the air path opened and closed by these dampers 546 and 548, for example, a fan (blower unit) 552 and a heater (heating unit) 554 are provided as the hot air supply unit 550. Further, a duct 592 communicating with the outside is provided on the downstream side of the heater 554, and a damper 590 is provided so as to be able to open and close the duct 592.

  As shown in FIG. 3A, in the circulation air blowing mode (toilet seat heating operation), the dampers 546 and 548 are closed, and the damper 590 is in a state in which the duct 592 is closed. An air path is formed. In this state, the air sent from the fan 552 is heated by the heater 554 to generate hot air, and this hot air is introduced into the toilet seat 410 via the sending unit 560. In the toilet seat 410, a warm air inner air passage 412 of warm air partitioned by a partition 418 is formed. The warm air introduced into the air passage 412 of the toilet seat 410 from the delivery unit 560 flows through the toilet seat 410 as indicated by an arrow, and returns to the upstream side of the fan 552 of the casing 500 via the return portion 570.

  On the other hand, as shown in FIG. 3B, when the dampers 546, 548, and 590 are opened, the warm air heated by the heater 554 flows into the duct 592. At this time, both ends of the air passage 412 in the toilet seat are closed by the dampers 590 and 594, the internal warm air is maintained, and the temperature of the toilet seat 410 can be prevented from rapidly decreasing.

FIG. 4 is a schematic diagram showing a specific example in which the drying operation is enabled by the duct 592.
FIG. 4A shows a state in which the toilet seat heating operation (first mode) is executed in the circulation air blowing mode. On the other hand, for example, as shown in FIG. 4B, the damper (first opening / closing portion) 590 and the duct (first air passage) 592 are below the air passage of the warm air sent from the heater 554. Can be provided. That is, the duct 592 extends below the circulation air passage that heats the toilet seat 410, and blows warm air toward the “butt” of the user sitting on the toilet seat 410 (drying operation: second mode). Can be. In this way, the user's “tail” can be dried with warm air, and a convenient and easy-to-use heated toilet seat device can be realized.

  The duct 592 is not limited to an application for drying the user's “buttock”, and may provide a heating effect by blowing hot air toward the user's body, for example. However, in each embodiment of the present application, a drying operation will be described as an example as a specific example.

FIG. 5 is a block diagram showing the main configuration of the heating toilet seat device of this example. In addition, in the same figure, the electrical connection between each element was represented by the continuous line, and the air path was represented by the broken line.
The casing 500 is provided with a first temperature detection unit 540, a damper 594, a damper 548, a damper 546, a blower unit 552, a heating unit 554, a second temperature detection unit 540, and a damper 590 in order from the upstream side of the air path. Yes. The control unit 510 controls operations of the air blowing unit 552, the heating unit 554, and the like based on the detection results of the first temperature detection unit 540 and the second temperature detection unit 542. In addition, about the arrangement | positioning relationship of each of these elements, the number of dampers, etc. which added various changes are also included in the scope of the present invention.
In the circulation air blowing mode, a circulation air passage including these elements is formed, and warm air circulates in the toilet seat air passage 412. Then, when an instruction for the drying operation is given, the control unit 510 appropriately operates these elements to switch to the drying operation.

  FIG. 6 is a flowchart showing the control when switching from the toilet seat heating operation to the drying operation.

First, as described above with reference to FIG. 4A, the toilet seat 410 is heated by warm air in the circulating air blowing mode (step S102). Then, for example, the user operates a “wet dry” switch on the remote controller to instruct a drying operation (step S104).
FIG. 7 is a schematic diagram illustrating a switch provided in the remote controller 200.
On the upper surface of the remote controller 200, infrared transmissive windows 231 for communication with the casing 500 are provided at both ends thereof. Further, a large washing switch 232, a small washing switch 234, a toilet lid closing switch 236, a toilet lid opening switch 238, a toilet seat opening switch 240, and the like are provided.

  Various switches are also provided on the front surface of the remote controller 200. In the remote controller of this specific example, a “dry” switch 242 for drying “wet” or the like is provided. Each time the user presses the switch 242, the start and stop of the drying operation are instructed alternately.

  Returning to FIG. 6 again, when the “drying” switch 242 of the remote controller is pressed, the control unit 510 receives an instruction to start the drying operation (step S104). Then, control unit 510 first controls air blowing unit 552 and heating unit 554 to change the air volume and temperature of the hot air (step S106). That is, the air volume and temperature of the warm air are changed from the air volume / temperature set for heating the toilet seat 410 to the air volume / temperature set for drying such as “wet”. And the amount and temperature of warm air are stabilized. This stabilization process may be executed, for example, by waiting for a predetermined time after changing the output to the air blowing unit 552 and the heating unit 554, or the first temperature detection unit 540 or the second temperature detection. The temperature of the warm air may be checked by the unit 542 or the like, and the apparatus may wait until the detected value reaches a predetermined target value. Since it is not desirable to make the user wait for a long time until the drying operation is started, the stabilization in step S106 is performed in a range in which the air volume and temperature of the hot air do not cause discomfort to the user. It is desirable to make it as short as possible.

  Thereafter, control unit 510 switches the air path (step S108). That is, the dampers 546, 548, 590, and 594 are operated to switch from the state shown in FIG. 3A or 4A to the state shown in FIG. 3B or 4B. Then, the drying operation is started (step S110).

  In this way, when the hot air blows out toward the “buttock” of the user sitting on the toilet seat 410, the air volume and temperature of the hot air are at or close to the set values for the drying operation. Therefore, when the hot air is blown toward the user's “tail” or the like by switching the air path, it is possible to prevent discomfort caused by the blowing of cold hot air or hot hot air.

FIG. 8 is a flowchart showing a second specific example of control when switching from toilet seat heating operation to drying operation.
FIG. 9 is a control timing chart of this example.

In this specific example, the control unit 510 controls the air blowing unit 552 to change the air volume (step S106A), then controls the heating unit 554 to change the temperature (step S106B). Switching is executed (step S108).
For example, if there is a relatively large difference between the air volume during the toilet seat heating operation and the air volume during the drying operation, the air volume is changed first so that the toilet seat heating operation can be performed in a shorter time. It becomes possible to switch to.

FIG. 10 is a flowchart illustrating a third specific example of control when switching from toilet seat heating operation to drying operation.
In this specific example, control unit 510 first controls heating unit 554 to change the temperature of the hot air (step S106B), then controls air blowing unit 552 to change the air volume (step S106A), and then Then, the air path is switched (step S108).
For example, in the case where the difference between the temperature of the warm air during the toilet seat heating operation and the temperature of the warm air during the drying operation is relatively large, the temperature can be changed in a shorter time by changing the temperature first. It is possible to switch from the toilet seat heating operation to the drying operation.

Next, control when switching from the drying operation to the toilet seat heating operation will be described.
FIG. 11 is a flowchart illustrating control when switching from the drying operation to the toilet seat heating operation.
When the drying operation is being performed (step S110), for example, when the user presses the “drying” switch 242 (see FIG. 7) of the remote controller, the control unit 510 receives an instruction to stop the drying operation (step S112). ). Then, control unit 510 first switches the air path (step S114). That is, the dampers 546, 548, 590, and 594 are operated to switch from the state shown in FIG. 3B or 4B to the state shown in FIG. 3A or 4A. And it changes to the set air volume and temperature (step S116), and the toilet seat heating operation is started (step S102).

  In this way, while the hot air is blowing out toward the “buttock” of the user sitting on the toilet seat 410, the air volume and temperature of the hot air are set to the set value of the drying operation or a state close to this. maintain. In other words, the warm air set for the toilet seat heating operation does not blow out toward the user. As a result, even when switching from the dry operation to the toilet seat heating operation, it is possible to prevent discomfort caused by the cold warm air or hot warm air blowing out toward the user's “buttock” or the like.

  Also in this specific example, the change in the air volume and temperature in step S116 may be performed substantially simultaneously, or the air volume may be changed first as described above with reference to FIG. 8, or as described above with reference to FIG. As described above, the temperature may be changed first.

  In the specific examples shown in FIGS. 6 to 11, the four dampers 546, 548, 590, and 594 are operated almost simultaneously at the time of switching the air path, but the present invention is not limited to this. That is, the opening / closing timings of these four dampers 546, 548, 590, and 594 do not have to be the same, and the air volume and temperature can be stabilized more quickly by appropriately shifting the opening / closing timing.

FIG. 12 is a flowchart showing a specific example in which the opening / closing timing of the damper is shifted. FIG. 13 is a conceptual diagram showing changes in the air path corresponding to this specific example.
Also in this specific example, when an instruction to start the drying operation is received (step S104) when the toilet seat heating operation is performed in the circulating air blowing mode (step S102) as shown in FIG. First, the air volume and temperature are changed (step S106). That is, the air volume and temperature of the warm air are changed to settings suitable for the drying operation. Note that this step may be divided into a plurality of steps as described above with reference to FIGS.

  Thereafter, control unit 510 changes to the outside air introduction mode (step S118). That is, as shown in FIG. 13B, the dampers 546 and 548 are opened. In this mode, outside air is introduced from the suction port 580 and is discharged from the discharge port 582 through the fan 552, the heater 554, and the toilet seat air passage 412. Thereafter, control unit 510 closes dampers 590 and 594 (step S119). Then, as shown in FIG. 13C, the warm air is discharged from the duct 592 and the drying operation is started (step S110).

  Thus, by shifting the timing of opening and closing the dampers 546, 548, 590, and 594 and first executing the outside air introduction mode, it becomes possible to bring the air volume and temperature of the warm air closer to the drying operation mode more quickly. . That is, in the circulating air blowing mode (FIG. 13A), since the warm air circulates in the toilet seat air passage 412, for example, to the heater 554 required to maintain the warm air at a predetermined temperature. The input power of can be small. On the other hand, in the dry operation mode (FIG. 13C), outside air is introduced and heated by the heater 554 to generate warm air, so that the power to be supplied to the heater 554 becomes relatively large.

  That is, if the circulation air blow mode is immediately shifted to the drying operation mode, the power supplied to the heater is insufficient immediately after the switching, and the temperature of the hot air may be lowered. On the other hand, in this specific example, as shown in FIG. 13B, first, the mode is changed to the outside air introduction mode, and the electric power necessary to warm the outside air to the temperature of the drying operation is input to the heater 554. To form a state. Thereafter, by opening the damper 590 and closing the damper 594, hot air having a temperature suitable for the drying operation can be immediately blown out from the duct 592.

  Also, regarding the air volume, the load on the fan 552 may be different because the conductance of the air path is different between the circulating air blowing mode (FIG. 13A) and the drying operation (FIG. 13C). On the other hand, by first executing the outside air introduction mode (FIG. 13B), the conductance of the air passage can be brought close to the state of the drying operation mode, and the operation state of the fan 552 can be made more quickly according to the conditions of the drying operation. It is possible to approach.

FIG. 14 is a flowchart showing a second specific example in which the opening / closing timing of the damper is shifted.
In this specific example, upon receiving an instruction to start a drying operation (step S104), control unit 510 first executes an outside air introduction mode (FIG. 13B) (step S118). Thereafter, the air volume / temperature is changed (step S106). That is, the air volume and temperature of the warm air are changed to settings suitable for the drying operation. Here, as described above with reference to FIGS. 8 to 10, the steps may be divided into a plurality of steps.
Thereafter, control unit 510 closes dampers 590 and 594 (step S119). Then, as shown in FIG. 13C, the warm air is discharged from the duct 592 and the drying operation is started (step S110).

  That is, in this specific example, after setting the outside air introduction mode, the settings of the fan 552 and the heater 554 are changed to change the air volume / temperature. Even in this case, the predetermined air volume and temperature can be obtained more quickly by bringing the load on the fan 552 and the heater 554 closer to the conditions of the drying operation.

Next, control when switching between the indoor heating operation and the drying operation will be described.
FIG. 15 is a conceptual diagram showing a heating toilet seat device that enables indoor heating operation and drying operation.
In this specific example, the downstream of the duct 592 branches into a duct (second air passage) 597 and a duct (first air passage) 598. A damper (first opening / closing part) 596 is provided at the branch part. The damper 596 can open and close the duct 597 and the duct 598 alternately. For example, by opening the duct 597 to the side surface or the rear surface of the casing 500, it is possible to heat the toilet room with warm air. On the other hand, if the duct 598 is opened toward the “butt” of the user sitting on the toilet seat as illustrated in FIG. 4, the drying operation can be performed. In this case, FIG. 15A shows the state of the indoor heating operation (third mode), and FIG. 15B shows the state of the drying operation (second mode).
In such a heating toilet seat device, it is desirable to devise control even when switching between the indoor heating operation and the drying operation.

  FIG. 16 is a flowchart showing control for switching from the indoor heating operation to the drying operation.

That is, when the indoor heating operation is performed in the state shown in FIG. 15A, when receiving an instruction to start the drying operation (step S104), the control unit 510 first changes the air volume / temperature. (Step S122). That is, the air volume / temperature of the warm air is changed to a setting suitable for the drying operation. Here, as described above with reference to FIGS. 8 to 10, the steps may be divided into a plurality of steps.
Thereafter, control unit 510 operates damper 596 to switch the air path (step S124). Then, as shown in FIG. 15B, the hot air is discharged from the duct 598, and the drying operation is started (step S110).

  That is, also in this specific example, the air volume / temperature is first changed, and then the blowing of warm air from the duct 598 is started. By doing so, it is possible to prevent the warm air of the air volume and temperature under the conditions of the room temperature heating operation from being blown on the user's “tail” and the like, and it is possible to realize a comfortable toilet seat device that is excellent in use feeling.

Here, control in the case of performing indoor heating during toilet seat heating will be described with reference to FIG. 3 as an example.
In the indoor heating operation, the damper 590 is opened, and the indoor heating of the toilet room is performed by the warm air blown from the duct 592. However, if only room heating is performed by the single hot air supply means 550, the toilet seat heating operation cannot be performed during that time. Therefore, when the toilet seat heating and the indoor heating are performed simultaneously, for example, the damper 590 is not fully opened and closed, but is maintained in a half-open state, and hot air is supplied to both the damper 590 and the air passage 412 in the toilet seat. What is necessary is just to control it. Note that the half-open state is included in the third mode described above. In this case, it is desirable to control the temperature of the warm air so as to warm the toilet seat to an appropriate temperature. Alternatively, the damper 590 may be opened and closed at a predetermined time interval to switch between the first mode and the third mode described above. In this case, the hot air supply means 550 is operated with the output for indoor heating when performing indoor heating, and the hot air supply means 550 is operated with the output for heating the toilet seat when performing toilet heating. It is desirable.

  FIG. 17 is a flowchart showing control for switching from the drying operation to the indoor heating operation.

  That is, when the drying operation is being performed in the state shown in FIG. 15B, when the instruction to stop the drying operation is received (step S112), the control unit 510 first operates the damper 596 to The path is switched (step S126). Then, as shown in FIG. 15A, the warm air is discharged from the duct 597. Thereafter, control unit 510 changes the air volume / temperature of the hot air (step S128), and room temperature heating is started (step S120).

  That is, also in this specific example, the air path is first switched, and then the air volume / temperature setting is changed. By doing so, it is possible to prevent the warm air of the air volume and temperature under the conditions of the room temperature heating operation from being blown on the user's “tail” and the like, and it is possible to realize a comfortable toilet seat device that is excellent in use feeling.

The embodiment of the present invention has been described above with reference to FIGS.
Hereinafter, configurations that can be added to each of these specific examples will be described.
FIG. 18 is a conceptual diagram illustrating the cross-sectional structure of the delivery unit 560 provided between the casing 500 and the toilet seat 410.
In the case of this specific example, the casing 500 is provided with a protruding duct 562. A damper 564 is provided at the end of the duct 562 so as to be freely opened and closed. The duct 562 may be retracted when the toilet seat 410 is opened, and the front end surface of the casing 500 may be a substantially flat surface. In the state where the toilet seat 410 is closed, the duct 562 protrudes and is inserted into the introduction port 414 provided in the toilet seat 410. In this state, warm air can be introduced into the air passage 412 of the toilet seat 410. Further, by appropriately providing a packing 568 made of an elastic material around the duct 562, it is possible to suppress the “leak” of warm air in the delivery unit 560. A similar structure can also be adopted for the reversing part 570.
With such a structure, when the toilet seat 410 is removed from the casing 500 and cleaned or washed with water, it can be easily removed and reattached.
