Description

  The present invention relates to a lifting toilet that can be installed in a toilet and the toilet itself can be raised and lowered.

  2. Description of the Related Art Conventionally, an elevating toilet that automatically raises and lowers a toilet seat and a toilet so that a user can easily use the toilet when using the toilet is known (see, for example, Patent Document 3).

  Here, the toilet described in Patent Document 1 detects that the user has stood in front of the toilet and raises the toilet seat. This makes it easy for an elderly person with weak legs to sit on the toilet seat, for example. In addition, the lifting toilet of Patent Document 1 has a function of lowering the toilet seat after a predetermined time when the user rises up and leaves the toilet seat. In this way, the user can sit on the toilet seat in a posture familiar to ordinary users by changing the settings as appropriate.

On the other hand, the lifting toilet described in Patent Document 2 detects that the user has left the toilet seat and moves the toilet up and down to a standard height position. As a result, the amount of lifting and lowering of the toilet is minimized when an adult or a child uses the toilet, or when the toilet is shared for stool or urine.
Japanese Unexamined Patent Publication No. 10-328076 (paragraph (0007), paragraph (0008), FIG. 3) JP-A-3-72126 (page 8, FIG. 10) JP 2008-19578 A

  These conventional techniques aim to improve the convenience of the toilet for the user, and achieve this purpose in each configuration. However, these conventional techniques have a fundamental problem to be solved when viewed from another viewpoint.

  Hereinafter, these problems of the prior art will be described in detail with reference to the drawings. FIG. 17 is a side view showing a state in which a toilet user stands up immediately after adding a hand, or a state in which the next user approaches the toilet 30 of the elevator toilet 3 immediately after the previous user leaves the toilet. FIG. 19 is a side view showing a state in which the toilet user suddenly falls to the toilet floor surface due to poor physical condition during the addition. FIG. 18 shows that immediately after the addition, the person or another person gets on the toilet 30 of the elevator 3 in order to clean the ceiling of the toilet or to replace the light bulb provided on the ceiling with a new light bulb. It is a side view which shows a state. FIG. 20 is a side view showing a state in which the person or another person wants to clean the toilet floor immediately after the addition.

  In the lifting toilet described in Patent Document 1, when the user stands up in the middle of the erection and tries to sit down again after a while, the toilet seat is already lowered and the height of the toilet seat is lowered. (See the toilet 30 of the conventional lift toilet 3 in FIG. 17). In particular, when the user is an elderly person whose hearing ability has deteriorated or a hearing impaired person, it is difficult to notice that the height of the toilet seat has been lowered because it is difficult to hear the sound of raising and lowering the toilet seat and it stands up toward the entrance of the toilet. This not only surprises the user, but also may cause the user to fall from the toilet seat to the toilet floor.

  Further, in the lifting toilet described in Patent Document 2, when the home position of the toilet bowl (a predetermined height at which the toilet bowl returns when the toilet bowl is not used) is high, when the user lowers the height of the toilet bowl and finishes adding, The toilet bowl also rises accordingly, and the upper front part of the toilet bowl may hit the back of the user's thigh or the buttocks, which may surprise the user. In particular, when the user is an elderly person with weak legs and legs, there is a risk that the toilet may fall out of balance due to the momentum that hits the body part (see the toilet 30 of the conventional elevator toilet 3 in FIG. 17).

  Also, if the toilet home position is high, immediately after the user places the toilet in a lower position, the user or another person cleans the toilet ceiling or replaces the bulb on the toilet ceiling with a new bulb. When riding on the toilet, the person may be surprised when the toilet rises toward the home position, or the person may fall from the toilet onto the toilet floor (the conventional elevator 3 shown in FIG. 18). (See toilet 30).

  On the other hand, when the home position of the toilet bowl is low, for example, after finishing adding the toilet with the toilet raised for a boy's small, the toilet and toilet that try to return to the home position when it falls to the toilet floor due to some physical disorder There is a risk that a foot or a hand may be pinched between the floor and the floor (see the toilet 30 of the conventional lift toilet 3 in FIG. 19). Toilet bowls are generally made of earthenware, and if you put your feet or hands between such heavy objects and the floor of the toilet, it can lead to serious injuries such as broken bones.

  Also, if the toilet home position is low, for example, if you try to wipe off the dirt on the bottom of the toilet immediately after adding the toilet in the boy's small state, the toilet will be placed between the toilet and the toilet floor. (See the toilet bowl 30 of the conventional lift toilet 3 in FIG. 20).

  In addition, if the user raises or lowers using a seating or a user standing in front of the toilet as a trigger, the toilet will move up and down during use when used without being seated, such as for boys. There are also problems such as poor usability and accidents due to contact with the user.

  An object of the present invention is to provide an elevating toilet that is not only excellent in usability but also ensures safety.

In order to solve the above-described problems, an elevator toilet according to the present invention is
A toilet lifting device;
A toilet body installed in the toilet lifting device so as to be movable up and down;
In a lifting toilet equipped with a detection unit that detects the presence or absence of a human body,
After the detection unit detects that no human body is present in a region where the toilet body can be raised and lowered, the toilet is automatically raised and lowered to a preset height.

  According to the present invention, it is possible to provide an elevating toilet that is not only excellent in usability but also ensures safety.

  Prior to describing the best mode for carrying out the present invention, the operation and effect of the present invention will be described.

  A first lifting toilet according to the present invention includes a toilet lifting and lowering device, a toilet main body installed on the toilet lifting and lowering device, and a detection unit that detects the presence or absence of a human body. After the detection unit detects that no human body is present in the liftable area, the toilet is automatically raised and lowered to a preset height.

  With the first lifting toilet according to the present invention having such a configuration, when the preset height (home position) of the toilet is set to a higher position, unlike the conventional lifting toilet, The toilet bowl does not automatically move up to the home position while standing up and repairing on the spot after adding a lower position, and the upper part of the front of the toilet bowl may hit the back of the user's thigh or the buttocks. There is no fear of surprise the user.

  In addition, when the toilet home position is set to a lower position, when the user who prefers the higher position raises the toilet bowl and then stands up while sitting on the toilet seat, Unlike a lifting toilet, the toilet is lowered to the home position and the height of the toilet seat is not lowered, and there is no possibility of surprise the user.

  Moreover, the 2nd raising / lowering toilet bowl which concerns on this invention is a toilet bowl provided with the toilet raising / lowering apparatus, the toilet bowl main body installed so that raising / lowering was possible in the toilet raising / lowering apparatus, and the detection part which detects the presence or absence of a human body, After the detection unit detects that there is no human body in the region in which the main body can be raised and lowered and the peripheral region of the region in which the body can be raised and lowered, the toilet is automatically raised and lowered to a preset height.

  In addition to the operation of the first elevator toilet described above, the second elevator toilet according to the present invention has the following operation. Specifically, when the home position of the toilet bowl is in a low position, even if the user suddenly gets sick and falls down on the floor of the toilet while adding, the toilet bowl is different from the conventional lifting toilet Is not lowered toward the home position, and there is no possibility that a part of the body such as a hand or a foot is caught between the toilet bowl and the toilet floor.

  Also, when the home position is in a lower position, even if another boy approaches the toilet for small use immediately after the boy has finished using the small toilet, unlike the conventional lift toilet, the toilet will descend toward the home position. The next boy can add as it is, and the convenience of the elevator is improved.

  Hereinafter, an elevator toilet according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a lifting / lowering toilet 1 according to the first embodiment of the present invention together with a toilet lifting / lowering region surrounded by a dotted line. FIG. 2 is a side view showing the state in which the toilet 1 shown in FIG. 1 is at the lower limit position together with the toilet lifting area surrounded by a dotted line. FIG. 3 is a side view showing a state in which the toilet shown in FIG. 1 is at the upper limit position together with a toilet raising / lowering region surrounded by a dotted line.

  An elevator toilet 1 according to the first embodiment of the present invention includes a toilet lifting device (not shown) and a toilet body (hereinafter simply referred to as “toilet bowl 10”) installed in the toilet lifting device so as to be lifted and lowered. A human body detection sensor 100 (see FIGS. 5 to 7) for detecting the presence or absence of a human body, and detecting that a human body does not exist in an area in which the toilet 10 can be raised and lowered (hereinafter referred to as a “toilet lifting area”). After the detection by the sensor 100, the toilet 10 is automatically raised and lowered to a preset height (home position).

  The elevating toilet 1 includes a toilet elevating device (not shown) for elevating the toilet 10 in the cabinet 50 shown in FIG. The toilet lifting / lowering device has a U-shape in a planar view that is not shown here and is a base plate that is flush with the toilet floor, a fixed portion that is suspended from the base plate, and supported by the fixed portion so as to be movable up and down. It consists of a moving part.

  The fixed part is provided with a guide part and a drive motor for raising and lowering the movable part, a control box for controlling the raising and lowering of the toilet 10, a water storage tank and the like. Further, the movable part is provided with a slider that slidably engages with the guide part of the fixed part, and a toilet coupling part with a protruding bolt that is coupled with the back part of the toilet bowl 10.

  Although it is not shown here on the side wall or counter of the toilet, the toilet bowl of the elevator 1 is raised or lowered according to the usage mode or preference of the user in the toilet or the height of the toilet bowl when the toilet bowl is not used ( It has a toilet lifting / lowering switch for setting the home position. The toilet lifting / lowering operation switch is electrically connected to the control box of the toilet lifting / lowering unit in a contact or non-contact manner, and enables two-way communication or one-way communication between the two.

  Around the toilet 10, there is provided a human body detection sensor 100 (see FIGS. 5 to 7) that detects the presence of a person in the toilet lifting / lowering region surrounded by a boundary region indicated by a dotted line in FIG. A specific example of the installation location of the human body detection sensor 100 will be described later.

  The human body detection sensor 100 is above the lower limit height Hd of the toilet lifting / lowering area surrounded by a dotted line in FIG. 2 and below the upper limit height Hu of the toilet lifting / lowering area surrounded by a dotted line in FIG. The presence / absence of a human body in the toilet lifting / lowering area is detected with the upper and lower projection areas of the toilet 10 having the projection area most widened with respect to the toilet floor as viewed. In addition, the human body detected here refers to a part of the body such as the user's hand, foot, and head, and is not limited to the entire body.

  The toilet 10 is moved up and down via the control circuit and the drive motor in the control box by the user operating the toilet lifting / lowering operation switch, and the human body is present in the lifting area of the toilet 10 after the user finishes adding. The toilet 10 is automatically raised and lowered to a preset height (hereinafter referred to as “home position”) only when the human body detection sensor 100 detects that it is not.

  The home position can be arbitrarily set according to the user's preference. For example, a child, a small woman, or a user who settles down when the height of the toilet bowl is used mainly lowers the home position. Depending on how the elevator 1 is used, such as large men or elderly people who are difficult to bend or bend their knees, etc. The user can freely set the home position as appropriate. Since this control routine is a well-known routine, the description with the flowchart is omitted.

  Unlike the control routine described above, the lift toilet 1 according to the present embodiment constantly monitors whether or not there is a person in the toilet lift area by means of a human body detection routine shown in FIG. 4 via a control box. That is, when the toilet 1 is turned on, this human body detection routine is always repeated. Then, for example, it is determined that a human body has been detected even if only a part of the body such as a human hand, foot, or waist is within the toilet lifting / lowering region.

  Specifically, the human body in the toilet lifting / lowering area is detected by turning on the power of the lifting / lowering toilet 1 (step S1). And when a human body exists in a toilet bowl raising / lowering area | region, this step S1 is repeated. That is, while at least a part of the human body is present in the toilet lifting / lowering region, for example, while the human body detection sensor detects a part of the body such as the user's hand, foot, or waist, the toilet 10 is in the home position. Avoid moving up and down. Then, the toilet 10 is raised and lowered to the home position when at least a part of the human body is no longer detected in the toilet raising and lowering region (step S2).

  Therefore, even if the user completes the add-on by this human body detection routine and sits away from the toilet 10, as long as the human body detection sensor detects the user's limbs and the like in the toilet lifting / lowering area, the toilet 10 is brought to the home position. The lifting / lowering operation is not performed.

  The human body detection routine in the toilet lifting / lowering area is a preferential routine compared with the automatic control routine of the lifting / lowering toilet 1 so that the user can use the toilet safely. Note that a timer counter step may be interposed between step S1 and step S2 of this human body detection routine, or a fixed time between steps S1.

  Next, a specific example of how to detect the presence / absence of a human body in the toilet installation location and the toilet lifting / lowering area will be described.

  The human body detection sensor used may be a sensor that can detect the presence or absence of a human body in the toilet lifting / lowering area according to the first embodiment of the present invention and the toilet lifting / lowering peripheral area according to the second embodiment described later. Any sensor may be used, for example, various sensors such as a photoelectric sensor, an infrared sensor, an ultrasonic sensor, and a heat sensitive sensor can be used.

  Here, a method of human body detection in the first embodiment will be described. FIG. 5 is a plan view showing an installation position of the human body detection sensor 110 (100) and a detection range 110A (100A) indicated by hatching. FIG. 6 is a front view showing a state where the user indicated by the dotted line is seated on the toilet 10 in FIG. 5 together with the installation positions of the human body detection sensors 110 and 120 (100). 7 is a side view showing a state where the user is going to sit away from the toilet 10 in FIG. 5 together with the installation positions of the human body detection sensors 110, 120, (100) and detection ranges 110A, 120A (100A) indicated by hatching. FIG.

  As shown in FIGS. 5 and 6, the human body detection sensor 110 detects the user's arm and flank, so that the toilet 10 is not returned to the home position by the routine shown in FIG. Also, as shown in FIG. 7, even after the user has finished adding, the human body detection sensor 110 detects the presence of the user's buttocks and returns the toilet 10 to the home position even when the user stands up with a slight bend. Do not.

  As a result, when the home position of the toilet 10 is set to a higher position as shown in FIG. 7, after the toilet 10 is placed in a lower position and added, the user can stand up and be dressed with his knees bent. Even so, the detection range 100A of the human body detection sensor 110 detects the rear side of the user's thigh and the presence of the buttocks, and the toilet 10 is automatically raised toward the home position unlike the conventional example shown in FIG. As a result, the front upper part of the toilet 10 hits the rear side or the buttocks of the user's thigh and surprises the user, or the user may turn forward and fall on the toilet floor. Absent.

  Although not shown in FIG. 7, even if the user stands up completely and the user leaves the detection range 110A of the human body detection sensor 110, for example, the ankle of one foot is within the detection range 120A of the human body detection sensor 120. In some cases, it is determined that the user is in the toilet lifting / lowering area, and the toilet 10 is not returned to the home position by the routine shown in FIG.

  Thus, when the home position of the toilet bowl 10 is set low, the toilet bowl 10 is lowered toward the home position unlike the conventional example shown in FIG. 17 even if the user is dressed up while standing up from the toilet bowl 10. There is no possibility that the foot is caught between the bottom of the toilet 10 and the toilet floor.

  In this case, particularly elderly persons with hearing loss and hearing-impaired persons are standing in a front-facing state, and according to the conventional elevator, it is difficult to notice the toilet rising sound to the home position, and the toilet 10 is behind the thigh. There is a risk of suddenly colliding with the side or the buttocks and causing the balance to fall to the toilet floor, but according to the elevator 1 according to the present embodiment, the safety that has been lacking in such a conventional elevator Sexuality can be ensured.

  Even if the user falls down on the toilet floor due to sudden physical condition deterioration such as dizziness after closing the lid 13 of the toilet 10, a part of the human body such as hands, feet, and head is detected by the human body detection sensor 120. As long as it is within the detection range 120A, unlike the conventional example shown in FIG. 19, the toilet 10 does not descend toward the home position, and a part of the user's body is sandwiched between the toilet bottom and the toilet floor. There is no risk of unexpected injury.

  In addition, since the toilet bowl 10 is generally made of earthenware and is a heavy article, it can be said that such a security guarantee according to the present invention is an excellent feature that is not found in a conventional lift toilet bowl.

  Subsequently, an elevator toilet according to a second embodiment of the present invention will be described with reference to the drawings. The lifting / lowering toilet 2 according to the second embodiment of the present invention is common to the lifting / lowering toilet 1 according to the first embodiment in terms of the basic configuration, but the human body detection region is lifted / lowered as in the first embodiment. In addition to the area, the toilet raising / lowering area is included in addition to the toilet raising / lowering area.

  Here, the toilet lifting / lowering peripheral region has a width that allows a person to stand around the warm water washing toilet seat of the toilet 20, and the height from the toilet floor to the lower limit position of the toilet 20 and the toilet ceiling from the toilet ceiling. A spatial region formed at a height up to the upper limit position.

  In addition, FIG. 8 is a perspective view showing the elevator toilet 2 according to the second embodiment of the present invention together with the outer boundary portion of the toilet raising / lowering peripheral region indicated by a one-dot chain line. Moreover, FIG. 9 is a side view which shows the outer side boundary part of the toilet bowl raising / lowering peripheral area | region shown in FIG. 8 with a dotted line. Moreover, FIG. 10 is a top view which shows the outer side boundary part of the toilet bowl raising / lowering periphery area | region shown in FIG. 8 with a dashed-dotted line. Moreover, FIG. 11 is a front view which shows the outer side boundary part of the toilet bowl raising / lowering periphery area | region shown in FIG. 8 with a dashed-dotted line. 12 is a perspective view showing the toilet lifting / lowering peripheral area formed between the outer boundary of the toilet lifting / lowering area indicated by a dotted line in FIG. 1 and the outer boundary of the toilet lifting / lowering peripheral area indicated by a dashed line in FIG. It is.

  In the elevator toilet 2 according to the second embodiment, the toilet raising / lowering region and the toilet raising / lowering peripheral region are detected by a common human body detection sensor 200.

  Hereinafter, a specific example of the human body detection sensor 200 will be described. Actually, an appropriate number of human body detection sensors are provided on the front surface of the cabinet or the upper part of the cabinet so that the human body can be detected in the toilet raising / lowering region and the toilet raising / lowering peripheral region. Located on the back wall of the toilet.

  FIG. 13 is a plan view showing the installation position of the human body detection sensor 210 (200) and the detection range 210A (200A) together with the toilet bowl 20 in the second embodiment. FIG. 14 is a front view showing the installation positions of the human body detection sensors 210 and 220 (200) for detecting the presence or absence of a human body together with the toilet bowl 20 in the second embodiment. FIG. 15 is a side view showing the installation positions of the human body detection sensors 210 and 220 (200) and the detection ranges 210A and 220A (200A) together with the user drawn with dotted lines standing in front of the toilet bowl 20. FIG. 16 is a side view showing detection ranges 210A and 220A of the human body detection sensors 210 and 220 together with a cleaner who draws the bottom of the toilet 20 with a dotted line during cleaning.

  As apparent from FIGS. 13 to 15, according to the lifting / lowering toilet 2 in the second embodiment, the user moves from the toilet 20 in which the home position is at a high position but is actually at a relatively low height. Immediately after standing up, unlike the conventional example shown in FIG. 17, the toilet 20 is raised toward the home position, and the front upper part of the toilet 20 hits the rear part or the buttocks of the user to surprise the user. Therefore, it is possible to prevent the user from falling over as a result.

  FIG. 17 shows a case where another boy enters the toilet and tries to use the toilet immediately after the boy has finished his small use toward the toilet 20 at a relatively low height and leaves the toilet. Unlike the conventional example, the toilet 20 does not rise to the home position on the upper side and surprise the person.

  In addition, when one boy stands in front of a toilet for a long time including the time to dress and tries to do small use, the toilet 20 starts to move up and down automatically during the small use. Also, there is no problem that the user experience is very poor and that an accident occurs in contact with the user.

  When the home position of the toilet 20 is set to a relatively low position, for example, a male user immediately increases the position of the toilet 20 and adds small use as shown in FIG. FIG. 20 shows the presence or absence of a human body in the toilet raising / lowering region and the toilet raising / lowering peripheral region by the human body detection sensor 220 when the user cleans the bottom of the toilet and cleans the toilet bottom by hand. Unlike the conventional example, the toilet 20 does not descend toward the home position and surprise the user, and there is no possibility that the user's hand is pinched between the toilet bottom and the toilet floor.

  In addition, by detecting the presence or absence of a human body in the space between the toilet bottom and the toilet floor, which is a part of the toilet bowl raising / lowering area, the human body detection sensor 220 detects the presence of a human body and suddenly becomes unwell Unlike the conventional example shown in FIG. 19, the toilet 20 does not descend toward the home position even if the user falls on the floor of the toilet, and a part of the human body such as a hand or a foot is placed between the bottom of the toilet 20 and the toilet floor. It is possible to reliably prevent pinching.

  In addition, immediately after the user adds the height of the toilet bowl 20 as the lower limit height, the person or another person gets on the toilet bowl 20 to clean the ceiling, or replaces the bulb provided on the ceiling with a new bulb. , The presence / absence of a human body in the toilet lifting / lowering area and the toilet lifting / lowering peripheral area is detected by at least one of the human body detection sensors 210 and 220, so that the toilet 20 is brought into the home position unlike the conventional example shown in FIG. It does not suddenly rise up and surprise the person, and this can prevent the person from falling onto the toilet floor.

  In the case of the second embodiment, even when there is a gap that does not allow a hand or a foot to be sandwiched between the toilet bottom and the toilet floor at the lower limit position of the toilet 20, the effect of the present invention can be exhibited. it can. Specifically, this interval belongs to the toilet raising / lowering peripheral region and does not belong to the toilet raising / lowering region. Therefore, in the form in which the human body detection sensor as in the first embodiment detects that there is no human body only in the toilet lifting / lowering area, the user's hand that has fallen into the toilet floor or Since the foot is below the toilet lower limit position, that is, outside the toilet lifting / lowering area, the toilet 20 descends toward the home position. After that, since the toilet 20 stops descending at the lower limit position, the user's hand or foot is not sandwiched between the toilet bottom and the toilet floor, but falls to the toilet floor and psychologically panics. If the toilet bowl 20 descends toward the user's hand or leg that has fallen, the user will be given further fear. However, in the case of the lifting / lowering toilet 2 according to the second embodiment, these hands and feet are in the toilet lifting / lowering peripheral region, so that this is detected by the human body detection sensor 220 shown in FIGS. There is an advantage that the descent to the position is stopped and the fear is not given to the user.

  The installation location of the human body detection sensor is not limited to the front surface of the cabinet as in the above-described embodiment, but other facilities installed in the toilet space such as the toilet body, remote control, cigarette, and counter, and the toilet space It may be an inner wall or the like.
