JP-A-2018-127489

In recent years, since the functions of sanitary cleaning devices are increasing, a large capacity is required for the control means, and as a result, the control means tends to be large. As a result, if the casing is attached to the case cover side above the internal space as in Patent Document 1, the casing becomes large and the floor is raised, which hinders the improvement of the design.

In order to solve this problem, there is a configuration in which the casing is miniaturized by attaching the control means to the case plate side, which has a relatively large space compared to the case cover side. However, a cleaning water supply means is provided on the case plate side, and the control means below the internal space is submerged due to water leakage, etc., increasing the possibility of malfunction or malfunction of the sanitary cleaning device. Challenges are born.

As described above, according to the configuration of the conventional sanitary cleaning device, it is difficult to reduce the risk of malfunction of the sanitary cleaning device and improve the design by reducing the size and floor of the casing.

The present invention has been made in view of the above problems, and achieves both a reduction in the risk of malfunction of the sanitary cleaning device and an improvement in design by downsizing and lowering the floor of the casing, and water in the casing. It is possible to provide a hygienic cleaning device with a high design that meets the needs of customers, such as an unprecedented low-floor design, while being able to use it for a long time without worrying about problems due to leakage.

The sanitary cleaning device according to one aspect of the present invention is a sanitary cleaning device provided with a water discharge means for discharging washing water for cleaning a local part of a human body, in which a device main body having a space formed inside a casing and the device main body. A washing water supply means for supplying at least the washing water of the water discharge means and a control means are arranged in the space, and the control means includes a first control means for controlling the water discharge means and a second control means. The lower surface of the second control means is attached at a position higher than the lower surface of the first control means, and the second control means performs signal processing from the human body detecting means for detecting the human body.

According to this configuration, by dividing the control means into the first control means and the second control means, the degree of freedom of arrangement in the casing internal space is increased, the casing can be made smaller and the floor is lowered, and the design is improved. Can be done. Further, by arranging the second control means above the first control means, it is unlikely that the second control means will be flooded even if the first control means is flooded. Further, since the second control means controls the human body detection means, when the first control means is exposed to water and causes a malfunction or malfunction, at least the human body can be detected, so that the risk of malfunction is reduced. It works. Therefore, it is possible to provide a hygienic cleaning device with a high design that matches the needs of customers, such as an unprecedented low-floor design, while being able to use it for a long time without worrying about problems due to water leakage in the casing. ..

In the sanitary cleaning device according to one aspect of the present invention, the second control means further controls the toilet lid opening / closing means.

According to this configuration, when the first control means is flooded and causes a malfunction or malfunction, at least the human body can be detected by the second control means that is not flooded and the toilet lid can be opened. If the human body detecting means and the toilet lid opening / closing means are not controlled by the second control means, the effect cannot be achieved, and the user can use the toilet bowl for the time being. Therefore, it is possible to provide a hygienic cleaning device with a high design that matches the needs of customers, such as an unprecedented low-floor design, while being able to use it for a long time without worrying about problems due to water leakage in the casing. ..

In the sanitary cleaning device according to one aspect of the present invention, preferably, a space having a smaller volume above the lower part is formed inside the casing, and the second control means has a smaller volume than the first control means.

According to this configuration, a small second control means having a small capacity is attached to the upper part where the volume of the casing internal space is small, and a first lower part having a relatively space length than the upper part to which the second control means is attached. Since the control means is provided, it is possible to reduce the size and floor of the sanitary cleaning device rather than providing a space for mounting the large first control means above the casing. Therefore, it is possible to provide a hygienic cleaning device with a high design that matches the needs of customers, such as an unprecedented low-floor design, while being able to use it for a long time without worrying about problems due to water leakage in the casing. ..

The lower surface of the case plate is attached so as to be covered, and the lower surface of the case plate is a slope that becomes lower from the rear to the front in order to allow water generated in the casing to flow in front of the casing, and both the first control means and the second control means are said. It is attached to the rear of the casing.

According to this configuration, the optimum miniaturization of the sanitary cleaning device can be realized. Further, since the water generated by the water leakage or dew condensation accumulated on the case plate flows to the front of the casing, the control means attached to the rear of the casing is less likely to be inundated. Therefore, it is possible to provide a hygienic cleaning device with a high design that matches the needs of customers, such as an unprecedented low-floor design, while being able to use it for a long time without worrying about problems due to water leakage in the casing. ..

In the sanitary cleaning device according to one aspect of the present invention, preferably, the first control means is attached to the case plate, and the second control means is attached to the case cover.

According to this configuration, when water leaks from the washing water supply means, the water accumulated in the case plate is drained from between the case cover and the case plate, so that the possibility of water entering the case cover is reduced. The possibility that the second control means will be exposed to water is further reduced as compared with the case plate to which the second control means is attached. Therefore, it is possible to provide a hygienic cleaning device with a high design that matches the needs of customers, such as an unprecedented low-floor design, while being able to use it for a long time without worrying about problems due to water leakage in the casing. ..

In the sanitary cleaning device according to one aspect of the present invention, preferably, the human body detecting means and the toilet lid opening / closing means are connected to the first control means via the second control means, and the first control means and the toilet lid opening / closing means are connected. The connecting line connecting the second control means has a length that allows the case cover and the case plate to bend in a combined state.

According to this configuration, the connection line connecting the functional means attached to the case cover and the control means attached to the case plate can be kept connected even when the case cover and the case plate are not combined. It is necessary to have a certain length, but if the number of connecting lines increases, the connecting lines become bulky when combined, which may lead to an increase in the size of the casing. According to this configuration, the function attached to the case cover is connected to the first control means attached to the case plate by a connecting wire extending from the second control means via the second control means also attached to the case cover. Therefore, the number of connecting lines can be reduced. Further, when the connecting line extending from the second control means to the first control means bends and the water generated due to vibration applied to the casing or the like splashes and adheres to the connecting line, the water bends along the connecting line. Can be prevented from flowing toward the control means because the water gathers and falls. Therefore, it is possible to provide a hygienic cleaning device with a high design that matches the needs of customers, such as an unprecedented low-floor design, while being able to use it for a long time without worrying about problems due to water leakage in the casing. ..

In the sanitary cleaning device according to one aspect of the present invention, preferably, the second control means executes a third control other than the human body detection when the first control means is abnormal.

According to this configuration, since the second control means executes the third control other than the human body detection when the first control means is abnormal, the user is closer to when there is no abnormality in the first control means when the first control means is abnormal. Can be used in the state. Therefore, it is possible to provide a hygienic cleaning device with a high design that matches the needs of customers, such as an unprecedented low-floor design, while being able to use it for a long time without worrying about problems due to water leakage in the casing. ..

On the other hand, the first microcomputer 10 is arranged on the left side where the water system unit is located, and the second microcomputer 20 is arranged on the right side where the wind system unit is located. According to this configuration, since the second microcomputer 20 is separated from the water system unit, the possibility of being flooded is reduced.

Here, the arrangement configuration of the first microcomputer 10 and the second microcomputer 20 in the casing 5 in the device main body 4 of the sanitary cleaning device 2 according to the present embodiment will be described with reference to FIG. FIG. 4 is a schematic diagram for promoting understanding, and in reality, as shown in FIG. 2, a plurality of functional means are arranged without gaps. In FIG. 4, the distance c and the distance d obtained by dividing the distance between the lowermost surface and the highest surface of the casing 5 are equal, the internal space of the casing 5 covering the range of the distance c is upward, and the casing 5 covering the range of the distance d. The internal space is on the bottom. Further, in FIG. 2, the distance a and the distance b obtained by dividing the distance between the frontmost surface and the rearmost surface of the casing 5 are equal, the internal space of the casing 5 covering the range of the distance a is rearward, and the casing 5 covers the range of the distance b. The internal space of is the front.

As shown in FIG. 4, the lower surface 20b of the second microcomputer 20 is attached at a position higher than the lower surface 10b of the first microcomputer 10. When the microcomputer has a protective part such as a cover, the lowermost surface including the cover is the lower surface.

If the opening and closing of the human body detection sensor 12 and the toilet lid 7 is not controlled by the second microcomputer 20, the effect cannot be achieved, and the user can use the toilet bowl for the time being.

A space having a smaller volume above the lower part is formed inside the casing 5, and the capacity of the second microcomputer 20 is smaller than that of the first microcomputer 10. The capacity is the number of PINs possessed by the microcomputer, and the larger the number of PINs, the larger the capacity. A small second microcomputer 20 having a small capacity is attached above the small volume of the internal space of the casing 5, and the first microcomputer 10 is placed below the upper part where the second microcomputer 20 is attached, which has a relatively long space. Therefore, it is possible to reduce the size and floor of the sanitary cleaning device 2 rather than providing a space for mounting the large first microcomputer 10 above the casing 5.

The casing 5 is composed of a case cover 5b and a case plate 5a, the height of the front surface of the case cover 5b is lower than that of the rear surface, the toilet lid 7 is attached so as to cover the front surface of the casing 5, and the lower surface of the case plate 5a is the casing. The slope becomes lower from the rear to the front because the water generated in the 5 flows to the front of the casing 5, and both the first microcomputer 10 and the second microcomputer 20 are attached to the rear of the casing 5. According to this configuration, the sanitary cleaning device 2 can be optimally miniaturized. Further, since the water generated by the water leakage or dew condensation accumulated on the case plate 5a flows to the front of the casing 5, the control means attached to the rear of the casing 5 is less likely to be inundated.

The first microcomputer 10 is attached to the case plate 5a, and the second microcomputer 20 is attached to the case cover 5b. According to this configuration, when water leaks from the washing water supply means 14, the water accumulated in the case plate 5a is drained from between the case cover 5b and the case plate 5a, so that there is a possibility that water may infiltrate into the case cover 5b. It gets lower. The possibility that the second microcomputer 20 is exposed to water is further reduced as compared with the case where the second microcomputer 20 is attached to the case plate 5a.

It is the length that bends when 5a is combined. According to this configuration, the wire harness 30 for connecting the functional means attached to the case cover 5b and the control means attached to the case plate 5a is in a connected state even when the case cover 5b and the case plate 5a are not combined. It is necessary to have a certain length so that the wire harness 30 can be maintained, but if the number of wire harnesses 30 is increased, the wire harnesses 30 become bulky when combined, which may lead to an increase in the size of the casing 5. According to this configuration, the function attached to the case cover 5b is the first microcomputer attached to the case plate 5a by the wire harness 30 extending from the second microcomputer 20 via the second microcomputer 20 attached to the case cover 5b. Since it is connected to 10, the number of wire harnesses 30 can be reduced. Further, when the wire harness 30 extending from the second microcomputer 20 to the first microcomputer 10 bends and water generated due to vibration applied to the casing 5 splashes and adheres to the wire harness 30, the wire harness 30 is aligned with the wire harness 30. Since water collects and falls in the deflection, it is possible to prevent the water from heading to each control means.

A space having a smaller volume above the lower part is formed inside the casing 5, and the capacity of the second microcomputer 20 is smaller than that of the first microcomputer 10. A small second microcomputer 20 having a small capacity is attached above the small volume of the internal space of the casing 5, and the first microcomputer 10 is placed below the upper part where the second microcomputer 20 is attached, which has a relatively long space. Therefore, it is possible to reduce the size and floor of the sanitary cleaning device 2 rather than providing a space for mounting the large first microcomputer 10 above the casing 5.

Here, an example of the inspection procedure of the second control means according to the embodiment of the present invention will be described with reference to FIG.

The second microcomputer 20 which is the second control means executes the third control other than the human body detection when the first microcomputer 10 has an abnormality. Since the second microcomputer 20 executes the third control other than the normal control (human body detection) when the first microcomputer 10 is abnormal, the user is closer to when there is no abnormality in the first microcomputer 10 when the first microcomputer 10 is abnormal. Can be used in the state.

The third control is, for example, a stool washing function for washing the bowl portion 3a with running water. According to this configuration, the user can continuously use the toilet bowl even when the first microcomputer 10 is abnormal.

As a means for the second microcomputer 20 to determine the abnormality of the first microcomputer 10, the second microcomputer 20 is provided with a function of detecting the abnormality of the first microcomputer 10. According to this configuration, it is not necessary to install a new component in the casing 5 for abnormality detection, and the size can be reduced. Further, a third means (not shown) for determining an abnormality in the first microcomputer 10 and reporting it to the second microcomputer 20 may be provided.
