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 lifting 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. 13 shows a state in which a toilet user (hereinafter simply referred to as “user”) stands up immediately after adding, or immediately after the previous user leaves the toilet, It is a side view which shows the state which approached. FIG. 14 is a side view showing a state in which the user suddenly falls to the toilet floor due to poor physical condition while adding. Further, FIG. 15 shows that the user or another person gets on the toilet 30 of the elevator 3 to clean the ceiling of the toilet or replace the light bulb provided on the ceiling with a new light bulb immediately after the addition. It is a side view which shows a state. FIG. 16 is a side view showing a state in which the user or another person wants to clean the bottom of the toilet immediately after the addition.

  In the lifting toilet described in Patent Document 1, when a user stands up in the middle of an add-on and tries to sit on the toilet seat again after leaving the toilet bowl, he / she comes to sit on the descending toilet seat and surprises the user ( FIG. 13 shows a toilet 30 of the conventional elevator toilet 3). In particular, when the user is an elderly person whose hearing has declined or a hearing impaired person, it is difficult to notice that the toilet seat is being 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 toilet home position (predetermined height at which the toilet returns when the toilet is not used) is high, the user lowers the height of the toilet and finishes adding, After leaving the toilet bowl, for example, when the user moves backward and approaches the toilet bowl again, the upper front part of the rising toilet bowl hits the rear side of the user's thigh and the buttocks, which surprises the user. In particular, when the user is an elderly person with weak legs, the body part may be pushed by an unexpected force by continuing to rise after the toilet hits the user's body part, and there is a possibility that the balance may be lost and fall down. Yes (see toilet bowl 30 of conventional elevator toilet 3 in FIG. 13). Since the toilet bowl is made of pottery and has a weight, even if a part of the toilet bowl hits the user, the user is pushed in an unexpected direction with a considerable force.

  Also, if the toilet home position is high, the user or another person can use the toilet in a lower position and move away from the toilet. If you try to get on the toilet to replace it with a new light bulb, the toilet is going up towards the home position, so if you don't stop the lift manually, the person will get out of the toilet (See the toilet bowl 30 of the conventional elevator toilet 3 in FIG. 15).

  On the other hand, when the home position of the toilet bowl is low, for example, when the toilet is lifted for boys' use and the urinal is lifted, and once it leaves the toilet bowl, it falls to the toilet floor due to some physical disorder, so it will return to the home position. There is a risk that a foot or a hand may be caught between the toilet bowl and the floor of the toilet (see the toilet bowl 30 of the conventional elevator toilet 3 in FIG. 14). 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.

  In addition, when the toilet home position is low, for example, when the urinal is moved away from the toilet immediately after the toilet is lifted for boys' use, and then the bottom of the toilet is wiped off, the toilet is directed to the home position. In addition to being difficult to wipe off if the downward movement of the toilet is not stopped, there is a risk that a hand may be caught between the bottom of the toilet and the floor of the toilet (conventional in FIG. 16). (Refer to the toilet 30 of the elevator 3).

  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,
When the detection unit detects that a human body is present in the toilet lifting / lowering effect area while the toilet body is moving up and down, the lifting operation of the toilet body is stopped.

  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.

  The lifting / lowering toilet according to the present invention includes a toilet lifting / lowering device, a toilet body installed on the toilet lifting / lowering device so as to be movable up and down, and a detection unit that detects the presence / absence of a human body. When the detection unit detects that a human body is present in the toilet lifting effect area, the lifting operation of the toilet body is stopped.

  The lifting / lowering toilet according to the present invention has such a configuration, so that when the preset height (home position) of the toilet is set to a higher position, the toilet is raised after the toilet is added at a lower position and the toilet is raised. While the toilet is automatically lifted toward the home position while dressing away from the home, if the user tries to sit on the toilet again for some reason, the lift of the toilet stops immediately, unlike a conventional elevator. There is no risk that the user will continue to ascend after the front upper part of the rising toilet collides with the rear side or buttocks of the user's thighs and pushes the user in an unexpected direction.

  In addition, when the home position of the toilet is set to a lower position, the user who prefers the higher position raises the toilet in the state where the toilet is lifted up, temporarily leaves the toilet and sits down on the toilet seat again after a while. When trying to do so, the toilet being lowered toward the home position stops immediately unlike the conventional elevator, and there is no possibility of surprise the user.

  In addition, if the home position of the toilet is in a lower position, even if the user's body suddenly gets worse with the toilet placed in a higher position and falls into the toilet floor, Unlike a conventional lift toilet, the toilet that is descending toward the position stops immediately, and there is no possibility that a part of the body such as a hand or a foot is caught between the toilet and the toilet floor.

  In addition, when the home position is in a lower position, when another boy approaches the toilet for small use immediately after the boy raises the toilet and uses the small toilet, the toilet is lowered toward the home position. However, unlike a conventional elevator, it stops immediately, and the next boy can add without having to lift the toilet from the home position, improving the usability of the elevator.

  Hereinafter, an elevator toilet according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an elevator toilet 1 according to an embodiment of the present invention, together with a toilet lifting / lowering influence area surrounded by an alternate long and short dash line. Moreover, FIG. 2 is a side view which shows the outer side boundary part of the toilet raising / lowering influence area | region shown in FIG. 1 with a dotted line. Moreover, FIG. 3 is a top view which shows the outer side boundary part of the toilet raising / lowering influence area | region shown in FIG. 1 with a dashed-dotted line. Moreover, FIG. 4 is a front view which shows the outer side boundary part of the toilet raising / lowering influence area | region shown in FIG. 1 with a dashed-two dotted line.

  An elevator toilet 1 according to an embodiment of the present invention includes a toilet lifting device (not shown), a toilet main body (hereinafter simply referred to as “toilet 10”) installed on the toilet lifting device, and a human body. A human body detection sensor 100 (see FIGS. 8 to 11) for detecting presence or absence, and when the toilet is lifted when the toilet user is sitting or around the toilet in the area where the toilet 10 moves up and down When the human body detection sensor 100 detects that a human body is present in an area that may pose some danger to the user (hereinafter referred to as a “toilet lift effect area”), the height is set to a preset height (home position). The toilet 10 that is moving up and down is immediately brought to an emergency stop.

  In addition, the toilet raising / lowering influence area said here means the space which put together the toilet raising / lowering area and the toilet raising / lowering peripheral area. The toilet lifting / lowering area is a space area in which the toilet 10 can be lifted / lowered, and an outer peripheral boundary portion thereof is indicated by a dotted line in FIG. Further, the toilet ascending / descending peripheral area has a width that allows a person to stand around the warm water flush toilet seat of the toilet 10, and the height from the toilet floor to the lower limit position of the toilet 10 and the upper limit position of the toilet 10 from the toilet ceiling. The outer peripheral boundary portion is indicated by a one-dot chain line in FIGS. 1 and 6, and the inner peripheral boundary portion is indicated by a dotted line in FIGS. In FIG. 6, a region sandwiched between the alternate long and short dash line is shown.

  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.

  The toilet bowl 10 is made of earthenware, and a warm water washing toilet seat 11 is provided on the upper surface of the toilet bowl. The warm water washing toilet seat 11 is provided with an operation switch unit 12 having a built-in control controller so that the user can perform local hot water washing after adding a supplement.

  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. 8 to 11) for detecting that a person is in the toilet lifting / lowering influence 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 a toilet as viewed from the lower limit of the toilet lifting / lowering influence area surrounded by a dotted line in FIG. 2, that is, above the toilet floor, and the upper limit of the toilet raising / lowering influence area, that is, lower than the toilet ceiling. Presence / absence of a human body in the toilet lifting / lowering influence area having the upper and lower projection areas of the outer zone of the band having a width enough to be raised by a person around the hot water washing toilet seat 11 having the projection area most widened with respect to the floor surface Is to be detected. The human body detected here includes at least 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 user finishes the addition and leaves the toilet 10 to set the toilet 10 in advance. When the human body detection sensor 100 detects that a human body is present in the toilet lifting / lowering effect area while moving up and down to the height (hereinafter referred to as “home position”), the toilet 10 is lifted and lowered immediately. It comes to stop.

  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.

  The lifting / lowering toilet 1 according to the present embodiment lifts and lowers the toilet while the toilet 10 is lifted and lowered toward the home position by a human body detection routine shown in FIG. 7 via a control box (not shown) and the human body detection sensor 100. It constantly monitors whether there is a human body in the affected area. That is, the human body detection routine is always repeated while the toilet 10 of the elevator 1 is moving up and down toward the home position. Then, for example, it is determined that a human body has been detected even if only a part of the body such as a person's hand, foot, or waist is within the toilet lift effect area.

  In the following description, “the user leaves the toilet bowl 10” means that the entire body of the user is completely removed from the toilet lifting / lowering effect area, and “the user approaches the toilet bowl 10” It means that at least a part of the body such as the user's hand or foot enters the toilet lifting effect area.

  Next, the human body detection routine described above will be described more specifically with reference to FIG. First, the toilet 10 receives a signal for starting the raising / lowering operation toward the home position, and at the same time, detects a human body in the toilet raising / lowering influence region (step S1). And when not detecting presence of a human body in the toilet raising / lowering influence area, this step S1 is repeated. When the toilet 10 is moved up and down toward the home position, if at least a part of the human body such as the user's hand, foot, and waist is present in the toilet lifting / lowering influence area, at least one of the human body detection sensors 100 configured of a plurality Any one of them detects this and immediately stops the raising / lowering operation toward the home position of the toilet 10 (step S2).

  Therefore, by this human body detection routine, the user finishes adding and temporarily moves away from the toilet bowl 10 to perform the raising / lowering operation to return the toilet bowl 10 to the home position. However, when the user approaches the toilet bowl 10 again, the human body detection sensor is activated. The user's limbs and the like are detected in the toilet lifting effect area, and the lifting / lowering of the toilet 10 is immediately stopped.

  The human body detection routine in the toilet lifting / lowering area is a priority routine over the control routine for returning the toilet 10 of the lifting / lowering toilet 1 to the home position so that the user can use the toilet safely.

  Next, a specific example of how the human body detection sensor 100 is installed in the toilet and how to detect the presence or absence of a human body in the toilet lift effect area will be described. In the present embodiment, a plurality of human body detection sensors 100 are provided on the front surface of the cabinet 50. This is an example of sensor arrangement, and the arrangement of sensors is not limited as long as the presence or absence of a human body in the affected area can be detected.

  In addition, as a human body detection sensor to be used, any sensor may be used as long as it is a sensor capable of detecting the presence or absence of a human body in the toilet lifting / lowering influence region which is the object of the present invention. For example, a photoelectric sensor, an infrared sensor, an ultrasonic sensor Various sensors such as a heat-sensitive sensor can be used.

  A method of human body detection in this embodiment will be described. FIG. 8 is a plan view showing a state in which the toilet 10 according to the present embodiment is at the lower limit position together with the detection range 100 </ b> A of the human body detection sensor 100. Moreover, FIG. 11 is a front view showing the installation positions of the human body detection sensors 110 and 120 (100) that detect the presence or absence of a human body when the toilet 10 is in the lower limit position together with the lifting / lowering toilet 1 in the present embodiment.

  When the home position of the toilet bowl 10 is at a high position, once the user stands up and leaves the toilet bowl 10, the toilet bowl 10 rises toward the home position. When entering, the presence of a part of the user's body is detected in the detection ranges 110A and 120A (see FIG. 10) of at least one of the human body detection sensors 110 and 120, and the ascending operation of the toilet 10 is immediately stopped. .

  FIG. 10 is a side view showing this human body detection state. As can be seen from a comparison between FIG. 10 and FIG. 13, the elevator toilet 1 according to the present embodiment is such that the toilet 10 continues to rise toward the home position as in the conventional example shown in FIG. It does not surprise the user by hitting a part of the user's body. Further, in the lifting toilet 1 according to the present embodiment, the toilet 30 is forcibly raised toward the home position as in the conventional example shown in FIG. The user or the buttocks is pushed in an unexpected direction, and this does not cause the user to fall on the toilet floor.

  In addition, in conventional elevators, when leaving the toilet and moving backwards and approaching the toilet again, especially elderly people with hearing loss or hearing-impaired persons, the rising sound of the toilet to the home position of the elevator The toilet bowl suddenly bumps into the back of the thigh and the buttocks and pushes up the back of the thigh and the buttocks, which may surprise the user and break the balance, leading to falling to the toilet floor. According to the lifting / lowering toilet 1 according to the embodiment, the safety that has been lacking in such a conventional lifting / lowering toilet can be reliably ensured.

  On the other hand, FIG. 9 is a plan view showing the state in which the toilet 1 according to the present embodiment is in the upper limit position together with the detection ranges 110A and 120A (100A) of the human body detection sensors 110 and 120 (100).

  By detecting the user with such a human body detection sensor 100 when the toilet 10 is raised, when the home position of the toilet 10 is set to be low, the user stands up from the toilet 10 and repairs away from the toilet 10. In the meantime, the toilet 10 descends toward the home position. Even if the user moves his / her foot below the toilet bottom while the toilet 10 is descending, the foot enters the detection range 120A of the human body detection sensor 120. The human body detection sensor 120 detects the presence of the human body and immediately stops the descent of the toilet 10 toward the home position. As a result, unlike the conventional example shown in FIG. 13, there is no possibility of the user's foot being pinched between the toilet bottom and the toilet floor.

  Further, when the home position is at a low position, when the boy completes the small use toward the toilet 10 positioned relatively high and leaves the toilet 10, the toilet 10 descends toward the home position, but immediately thereafter. When another boy enters the toilet and tries to use it, a part of the human body is detected by one of the human body detection sensors 100, and the lowering of the toilet 10 is immediately stopped. As a result, it is possible to prevent a subsequent user from wasting time and labor to raise the toilet 10 that has reached the home position at the low position to the high position again.

  Further, when the user leaves the toilet 10, the toilet 10 descends toward the home position. At that time, even if the user falls to the toilet floor due to sudden physical condition such as dizziness, hands, feet, head, etc. As soon as a part of the human body enters the detection range 120A of the human body detection sensor 120, the lowering of the toilet 10 is immediately stopped, and a part of the user's body is connected to the bottom of the toilet as in the conventional example shown in FIG. There is no risk of unexpected injury from being sandwiched between the toilet floor.

  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.

  FIG. 9 is a side view showing a detection range of the human body detection sensor 100 when the toilet is in the upper limit position together with a cleaner who draws a bottom portion of the toilet with a dotted line during cleaning. As shown in the figure, when the home position of the toilet bowl 10 is set to a relatively low position, for example, as described above, the male user immediately increases the position of the toilet bowl 10 and adds the small duty. When the bottom of the toilet bowl 10 is bent to be cleaned and the bottom of the toilet bowl is cleaned, at least one of the human body detection sensors 110 and 120 detects the presence / absence of a human body in the toilet lifting / lowering effect region. Is immediately stopped, the toilet 10 is easily cleaned, and the toilet 10 continues to descend toward the home position, so that the user's hand is placed on the bottom of the toilet and the toilet floor as in the conventional example shown in FIG. There is no risk of being caught between the surfaces.

  In addition, even if the user leaves the toilet 10 after adding, and the toilet 10 starts to descend toward the home position, even if the user feels sick and suddenly falls down on the toilet floor, By detecting a part of the body, such as the user's hand or foot, between the bottom of the toilet bowl and the toilet floor using the human body detection sensor 120, the lowering of the toilet 10 is immediately stopped. Accordingly, a part of the human body such as hands and feet is not sandwiched between the bottom of the toilet 10 and the toilet floor as in the conventional example shown in FIG.

  Moreover, immediately after the user adds the height of the toilet bowl 10 as the lower limit height, the toilet bowl 10 is left, and then the person or another person gets on the toilet bowl 10 to clean the ceiling or prepare for the ceiling. When the light bulb is replaced with a new light bulb, the user leaves the toilet bowl 10 and the toilet bowl 10 starts to rise toward the home position at a higher position. However, a person who wants to perform a cleaning operation or the like thereafter When entering the up-and-down influence area, at least one of the human body detection sensors 110 and 120 detects this and immediately stops the ascent of the toilet 10 toward the home position. Therefore, unlike the conventional example shown in FIG. 15, the cleaner does not need to temporarily stop the lifting operation of the toilet 30 by operating the toilet lift switch, and the cleaner can keep the toilet 30 rising toward the home position. There is no such thing as getting on the toilet 30 and losing balance and falling on the toilet floor.

  As shown in FIG. 10, when the user is about to sit on the toilet 10, the human body detection sensor 110 detects the presence of the user's foot or waist in the toilet lifting / lowering effect area, and the toilet 10 is placed in the home according to the routine shown in FIG. I try not to return to position.

  While the user is seated on the toilet 10, the user's arm and flank are in the detection range 110A of the human body detection sensor 110, and the toilet is moved up and down to the home position via the human body detection sensor 110. Do not do.

  Further, even when the user finishes adding and leaves the toilet 10 and starts to move upward toward the home position of the toilet 10, when the user sits again, the user is slightly bent as shown in FIG. At that time, the human body detection sensor 110 detects the presence of the user's buttocks and immediately stops rising toward the home position of the toilet 10. As a result, when the user sits on the toilet 10, the toilet 10 is completely stopped, so that the user is surprised, or the lifting force of the toilet 10 is applied to the rear side of the user's thigh and the buttocks. There is no risk that the user will turn forward and fall on the toilet floor.

  Although not shown in the figure, even when the user stands up completely and the user leaves the detection range 100A of the human body detection sensor 100 and the toilet 10 descends toward the lower home position, for example, one foot 7 again, it is determined that this foot exists within the detection range 120A of the human body detection sensor 120, and the descent of the toilet 10 to the home position is immediately stopped by the routine shown in FIG. To do.

  As a result, when the home position of the toilet bowl 10 is set to a low level and the user repairs away from the toilet bowl 10, the user's feet are placed on the toilet bowl 10 and the toilet floor surface while the toilet bowl 10 is lowered to the home position. If there is an accidental entry, the foot may not be caught between the bottom of the toilet 10 and the toilet floor, unlike the conventional example shown in FIG.

  In addition, in the case of this embodiment, there exists a merit peculiar to toilet bowl raising / lowering influence area | region including the space between a toilet bowl raising / lowering area | region and a toilet floor surface. Specifically, if the toilet lifting effect area does not include this space, if the user's hand or foot that has fallen into the toilet floor is below the toilet lower limit position, that is, outside the toilet lifting effect area, the human body The detection sensor detects that there is no human body in the toilet lifting effect area, and tries to return the toilet to the home position. Actually, the toilet 10 descends toward the home position, and then the toilet 10 stops descending at the lower limit position, so that the user's hand or foot is not sandwiched between the toilet bottom and the toilet floor. However, when the toilet 10 descends toward the hand or foot of a user who has fallen to the toilet floor and is psychologically panicked, the user is given further fear.

  However, in the case of the lifting / lowering toilet 1 according to the present embodiment, since the toilet lifting / lowering effect area includes the space between the toilet lifting / lowering area and the toilet floor, these hands and feet exist in the toilet lifting / lowering influence area. Thus, this is detected by the human body detection sensor 120 shown in FIGS. 8 to 11, and there is an advantage that the descent of the toilet 10 to the home position is urgently stopped so that such a feeling of 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.

  Further, the toilet lifting and lowering influence area may be an area surrounded by a rectangular parallelepiped indicated by a two-dot chain line in FIG. 12, or may be an area surrounded by a vertically long rectangular parallelepiped where the upper surface of the lifting and lowering area in FIG. .
