Further, inside the casing 4, a “toilet seat heater” for warming the toilet seat 2, a “warm air drying function” for drying by blowing warm air toward the “buttock” of the user sitting on the toilet seat 2, A “deodorizing unit”, an “indoor heating unit”, or the like may be provided as appropriate.

Next, the structure of the nozzle unit 10 provided in the sanitary washing device 1 will be described with reference to FIG.
FIG. 2 is a cross-sectional view illustrating a part of the sanitary washing device according to the embodiment.

  As shown in FIG. 2, the nozzle unit 10 includes a cleaning nozzle 100, a cable rack 130, a drive unit 140, a base 150, and a cleaning unit 160.

  In the following description of the embodiment, the advancing direction of the cleaning nozzle 100 toward the bowl 6a is “front”, and the opposite direction is “rear”. Also, two directions that are perpendicular to the front-rear direction and that are along the horizontal direction are “right side” and “left-side”, and two directions that are perpendicular to the front-rear direction and left-right direction are “upward” and “lower”. To do.

  The cleaning nozzle 100 has a nozzle head 110 and a cylinder 120. The nozzle head 110 has a water discharge port 111 and a joint 112. When the cleaning water is supplied to the nozzle head 110 via the joint 112, the cleaning water is discharged from the water outlet 111. Water is discharged from the water outlet 111 toward the “butt” and the like, so that the human body is locally cleaned. The cylinder 120 is configured to be able to store at least a part of the nozzle head 110.

  The cleaning nozzle 100 is provided on the base 150, and the nozzle head 110 and the cylinder 120 are provided to be slidable with respect to the base 150. The nozzle head 110 is slidable with respect to the cylinder 120.

  The cable rack 130 is made of a flexible material. Concavities and convexities are formed on the side surface of the cable rack 130 and engaged with the gear 142. The drive unit 140 is fixed to the base 150 and includes, for example, a motor and a gear. The drive unit 140 can appropriately reduce the drive output and output it to the gear 141 and the gear 142. By driving the drive unit 140, the gears 141 and 142 rotate, and the rotational driving force is converted into a linear driving force via the cable rack 130.

  One end of the cable rack 130 is fixed to the nozzle head 110 of the cleaning nozzle 100. For this reason, when the cable rack 130 is driven by the drive unit 140, a force is applied to the cleaning nozzle 100, and the cleaning nozzle 100 is moved forward and backward.

  Locking pieces (not shown) are provided at the rear end of the outer wall of the nozzle head 110 and the front end of the inner wall of the cylinder 120. When the nozzle head 110 slides a predetermined distance toward the front, these locking pieces are locked with each other, and the sliding of the nozzle head 110 with respect to the cylinder 120 is restricted. For this reason, the force applied to the nozzle head 110 by the drive unit 140 is transmitted to the cylinder 120 through the engaged locking piece, and the cylinder 120 is slid.

  The cleaning unit 160 is provided in the front part of the nozzle unit 10. The cleaning unit 160 is positioned in front of the cleaning nozzle 100 when the cleaning nozzle 100 is accommodated in the nozzle unit 10. The cleaning unit 160 is provided so as to be rotatable with respect to the cap 168 fixed to the base 150. When the cleaning nozzle 100 slides forward, the cleaning section 160 is pushed upward by the cleaning nozzle 100.

Next, the cleaning unit 160 will be described with reference to FIGS. 3 and 4.
FIG. 3 is a rear view illustrating the cleaning unit of the sanitary cleaning device according to the embodiment.
FIG. 4 is a side view illustrating a part of the cleaning unit of the sanitary cleaning device according to the embodiment.
FIG. 4 shows a state where the cleaning unit 160 is pushed up by the cleaning nozzle 100 and water is discharged from the cleaning unit 160. 4A shows a state when water is discharged from the water outlets 163 to 166, and FIG. 4B shows a state when water is discharged from the water outlets 161 and 162. Yes.

  As illustrated in FIG. 3, the cleaning unit 160 includes water discharge ports 161 to 166 and a connection unit 167. The connection unit 167 is connected to a tube or the like (not shown), and water is supplied into the cleaning unit 160 via the connection unit 167. The water discharge ports 161 to 166 are provided on the back side of the cleaning unit 160 side by side in a substantially horizontal direction.

  The water discharge ports 161 and 162 are provided near the center in the left-right direction of the cleaning unit 160. The water outlets 163 and 164 are provided on the right side of the water outlets 161 and 162, and the water outlets 165 and 166 are provided on the left side of the water outlets 161 and 162. When the cleaning unit 160 is pushed up by the cleaning nozzle 100, the water discharge ports 161 and 162 face the approximate center of the cleaning nozzle 100 in the left-right direction. The water discharge ports 163 and 164 face the right side portion of the cleaning nozzle 100, and the water discharge ports 165 and 166 face the left side portion of the cleaning nozzle 100.

  As shown in FIG. 4A and FIG. 4B, the water discharge angles are different between the water discharge ports 161 and 162 and the water discharge ports 163 to 166. Specifically, the water outlets 161 and 162 are inclined more toward the rear than the water outlets 163 to 166.

  Below, a more specific example is shown. The water discharge ports 161 to 166 are provided on the surface S <b> 1 of the cleaning unit 160. The water discharge ports 163 and 165 discharge water in a direction inclined at an angle α forward with respect to the orthogonal direction of the surface S1. Similarly, the water discharge ports 164 and 166 discharge water in a direction inclined by an angle β toward the front side with respect to the orthogonal direction of the surface S1. The angle α is equal to the angle β, for example. On the other hand, the water discharge ports 161 and 162 discharge water in a direction inclined at an angle γ toward the rear side with respect to the orthogonal direction of the surface S1.

  Not limited to this example, the water discharge ports 163 to 166 discharge water in the direction orthogonal to the surface S1 (that is, the angles α and β are 0), and the water discharge ports 161 and 162 discharge water in the direction inclined by the angle γ toward the rear side. May be. Alternatively, the water discharge ports 161 and 162 may discharge water in the direction orthogonal to the surface S1 (that is, the angle γ is 0), and the water discharge ports 163 to 166 may discharge water in the directions inclined by the angles α and β toward the front side. That is, the water discharge angles of the water discharge ports 161 and 162 provided on the central side in the left-right direction of the cleaning unit 160 are inclined rearward from the water discharge angles of the water discharge ports 163 to 166 provided on the side of these water discharge ports. If it is, each water discharge angle can be changed appropriately.

Next, the operation of the cleaning nozzle 100 and the cleaning operation of the cleaning nozzle 100 by the cleaning unit 160 will be described with reference to FIGS. 5 and 6.
5 and 6 are side views illustrating the operations of the cleaning nozzle and the cleaning unit in the sanitary cleaning device according to the embodiment.

  The cleaning nozzle 100 is accommodated in the casing 4 as shown in FIG. 5A when not in use. In this state, the front of the cleaning nozzle 100 is covered with the cleaning unit 160 and the shutter 4a.

  When local cleaning is performed by the cleaning nozzle 100, the cleaning nozzle 100 slides forward. When the cleaning nozzle 100 slides forward, as shown in FIG. 5B, the cleaning nozzle 100 comes into contact with the cleaning unit 160, and the cleaning unit 160 and the shutter 4a are pushed upward. When the cleaning unit 160 and the shutter 4 a are pushed up by the cleaning nozzle 100 and the tip of the cleaning nozzle 100 advances forward from the tip of the cap 168, water discharge is started from the water discharge ports 161 to 166. At this time, for example, water is directly applied from the water discharge ports 161 and 162 to the front surface S2 of the cleaning nozzle 100.

  Thereafter, the cleaning nozzle 100 slides forward as shown in FIG. 6A until the water discharge port 111 reaches a predetermined position. When the cleaning nozzle 100 reaches a predetermined position, water is discharged from the water outlet 111 of the nozzle head 110 toward the user's local area, and cleaning is performed. When the local cleaning is completed, the cleaning nozzle 100 slides backward toward the casing 4. While the cleaning nozzle 100 advances and retracts, water is discharged from the cleaning unit 160 toward the cleaning nozzle 100, and the cleaning nozzle 100 is cleaned.

  As shown in FIG. 6B, when the cleaning nozzle 100 moves backward and immediately before being stored in the casing 4, water is again directly applied to the front surface S <b> 2 of the cleaning nozzle 100 from the water outlets 161 and 162. It is done. Thereafter, water discharge by the water discharge ports 161 to 166 is stopped, and the cleaning operation of the cleaning nozzle 100 by the cleaning unit 160 is completed. Thereafter, the cleaning nozzle 100 is retracted to a predetermined position, and is stored in the casing 4 as shown in FIG.

Next, the cleaning effect on the cleaning nozzle 100 will be described with reference to FIG.
FIG. 7A is a simulation result showing the cleaning effect on the cleaning nozzle.
FIG. 7B and FIG. 7C are schematic diagrams for explaining the parameters of the simulation.
FIG. 7A shows a simulation result when water is discharged from the water discharge ports 161 to 166 of the cleaning unit 160 to the cleaning nozzle 100 at the same water discharge angle.

  In FIG. 7A, the horizontal axis represents the water discharge angle θ with respect to the cleaning nozzle 100, and the vertical axis represents the removal rate of dirt attached to the cleaning nozzle 100. FIG. 7A shows the change in the removal rate when the angle θ is changed on the front surface, the upper surface, the lower surface, the right side surface, and the left lower surface of the cleaning nozzle 100.

  The angle θ represents the angle at which water is discharged with respect to the advance direction (front) of the cleaning nozzle 100, as shown in FIG. 7B. Each surface of the cleaning nozzle 100 is as represented in the schematic front view of FIG. That is, the front end surface of the cleaning nozzle 100 is the front surface, and the upper, lower, left, and right curved surfaces of the cleaning nozzle 100 are divided into upper, lower, left, and right side regions to simulate the removal rate on each surface. .

  As can be seen from FIG. 7A, the upper surface of the cleaning nozzle 100 has a very high removal rate regardless of the angle θ. This is because water is discharged directly from the water discharge ports 161 to 166 while being close to the cleaning unit 160. The removal rate of the right side surface, the left side surface, and the lower surface increases as the angle θ decreases. This is because water becomes easier to flow along the surface of the cleaning nozzle 100 as θ decreases. That is, as the distance of the water flowing on the surface of the cleaning nozzle 100 becomes longer, the surface dirt is easily removed.

  On the other hand, the removal rate of the front surface decreases as the angle θ decreases. This is due to the following reason. The water spouted on the upper surface flows on the right or left side, flows down from the lower surface, and does not flow much on the front surface. The dirt adhering to the front surface mainly causes water to be spouted near the tip of the cleaning nozzle 100 when moving out of the casing 4 and when storing in the casing 4 is completed. Removed by direct contact with water. As the angle θ decreases, it becomes difficult for water to hit the front surface, and the water flowing through the front surface also decreases, so the removal rate with respect to the front surface decreases.

  In this embodiment, in this embodiment, the water discharge angle of the water discharge ports 161 and 162 that discharge water to the center side of the cleaning nozzle 100 in the left-right direction is behind the water discharge angle of the water discharge ports 163 to 166 that discharge water to the left and right of the cleaning nozzle 100. Tilt to. That is, the angle θ is increased for water discharge to the center side of the cleaning nozzle 100, and the angle θ is decreased for water discharge to the left and right of the cleaning nozzle 100.

  According to such a configuration, it is possible to increase the removal rate for the right side surface, the left side surface, and the bottom surface by the water discharge ports 163 to 166 while increasing the removal rate for the front surface by the water discharge ports 161 and 162. Therefore, according to the sanitary washing device according to this embodiment, the washing nozzle can be effectively washed and kept clean.

  In addition, from the result shown to Fig.7 (a), it is also considered that the water discharge angle of the water outlets 163-166 inclines back rather than the water discharge angle of the water outlets 161 and 162. FIG. However, since the water discharged from the water discharge ports 163 to 166 does not easily hit the center in the left-right direction of the front surface, the front surface is not sufficiently removed and the removal rate is reduced. Therefore, by tilting the water discharge angle of the water discharge ports 161 and 162 to the rear side from the water discharge angle of the water discharge ports 163 to 166, the water discharge angle of the water discharge ports 163 to 166 is rearward of the water discharge angle of the water discharge ports 161 and 162. The cleaning effect of the cleaning nozzle 100 can be further enhanced as compared with the case where the nozzle is tilted to the side.

  In a part of the cleaning operation, it is desirable that water is directly applied to the front surface of the cleaning nozzle 100 from the water discharge ports 161 and 162. By directly applying water to the front surface from the water discharge ports 161 and 162 whose water discharge angle is inclined to the rear side, it is possible to further increase the removal rate of dirt on the front surface.

  As the timing of directly applying water to the front surface of the cleaning nozzle 100, as shown in FIGS. 5B and 6B, when the cleaning nozzle 100 advances from the casing 4, and when the cleaning nozzle 100 moves to the casing 4. It is possible to move back in.

When water is directly applied to the front surface when the cleaning nozzle 100 advances from the casing 4, it is desirable that the front end of the cleaning nozzle 100 protrude from the casing 4 as shown in FIG. By discharging water from the cleaning unit 160 with the front end of the cleaning nozzle 100 coming out of the casing 4, water discharged from the cleaning unit 160 enters the nozzle unit 10, or the nozzle unit 10, the casing 4, Can be prevented from entering the gap.
The state in which the tip of the cleaning nozzle 100 protrudes from the casing 4 means that the cleaning unit 160 and the shutter 4a are pushed up by the cleaning nozzle 100 as shown in FIG. Also means that it has advanced forward.

After the cleaning nozzle 100 has advanced from the casing 4, cleaning is continuously performed by the cleaning unit 160 until the cleaning nozzle 100 moves back into the casing 4. The water discharged toward the cleaning nozzle 100 flows on the surface of the cleaning nozzle 100 together with the removed dirt. At this time, part of the water may flow to the front surface of the cleaning nozzle 100, and dirt flowing from the upper surface may reattach to the front surface.
In this regard, when the cleaning nozzle 100 is retracted into the casing 4, water is directly applied to the front surface of the cleaning nozzle 100, thereby removing dirt that has flowed from the outer peripheral surface of the cleaning nozzle 100 to the front surface and reattached to the front surface. As a result, the cleaning nozzle 100 can be kept clean.
The outer peripheral surface of the cleaning nozzle 100 means an upper surface, a lower surface, a right side surface, and a left side surface other than the front surface of the cleaning nozzle 100.

  Further, for example, as shown in FIG. 6A, it is desirable that the cleaning nozzle 100 (nozzle head 110) is not curved and smoothly curved between the outer peripheral surface and the front surface. By curving between the outer peripheral surface and the front surface, water flowing on the outer peripheral surface can easily flow to the front surface, and dirt on the front surface can be more effectively removed.

  In the above-described embodiment, an example in which the cleaning unit 160 is provided with six water discharge ports has been described, but the present embodiment is not limited to this. The cleaning unit 160 includes a water outlet that applies water to the left side of the cleaning nozzle 100, a water outlet that applies water to the right side of the cleaning nozzle 100, and a water outlet that applies water to the center in the left-right direction of the cleaning nozzle 100 from these water outlets. It is sufficient that at least three water outlets of the water outlet are provided. Among these three water outlets, the water discharge angle of the water outlet that applies water to the central side of the cleaning nozzle 100 is inclined rearward from the water discharge angle of the water outlet that applies water to the left and right, thereby cleaning the cleaning nozzle 100. It can be effectively removed.

  However, it is desirable that the water discharged to the center in the left-right direction of the cleaning nozzle 100 does not directly hit the water outlet 111. This is because when water directly hits the water outlet 111, water is scattered at the water outlet 111 and the removal rate of dirt is also reduced. For this reason, in order to remove dirt effectively, as shown in FIG. 3, a plurality of water discharge ports 161 and 162 are formed at the center in the left-right direction of the cleaning unit 160 so as to be separated from each other. It is desirable to configure so that water does not come into direct contact with water.

  In the above-described embodiment, the case where the cleaning nozzle 100 includes the nozzle head 110 and the cylinder 120 and the two-stage advance / retreat operation is performed by these members has been described. However, the cleaning nozzle 100 includes only the nozzle head 110. You may have. Alternatively, the cleaning nozzle 100 may further include other cylinders configured to be slidable with respect to the base 150 in addition to the nozzle head 110 and the cylinder 120. The cleaning nozzle 100 may include a plurality of nozzle heads 110 arranged in the left-right direction, for example. In this case, for example, the above-described cleaning unit 160 is provided for each nozzle head 110.

The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention. For example, the shape, dimensions, material, arrangement, installation form, and the like of each element included in the cleaning nozzle 100 of the nozzle unit 10 are not limited to those illustrated, and can be changed as appropriate.
Moreover, each element with which each embodiment mentioned above is provided can be combined as long as technically possible, and the combination of these is also included in the scope of the present invention as long as it includes the features of the present invention.
