Description

  The present invention relates to a sanitary washing device that discharges heated washing water toward a human body.

  Conventionally, a sanitary washing device for washing a local part of a human body is well known. This type of sanitary washing apparatus includes pulsation generating means for adding pulsation to washing water heated by a heat exchanger and obtaining a feeling of washing and washing power with a small amount of washing water. In addition, a cleaning nozzle that discharges cleaning water to a human body is advanced and retracted between a storage position and a cleaning position. When not in use, the cleaning nozzle is stored in the storage position in the casing, and when in use, the cleaning nozzle is moved by the nozzle drive means to the cleaning position so that the direction of discharge of the cleaning water is toward the user seated on the toilet seat The convenience of In addition, a hygienic cleaning device that adopts a mode (so-called move cleaning) in which the cleaning nozzle is moved by a minute distance during cleaning to change the cleaning position by using advance / retreat by the nozzle drive means of the cleaning nozzle has been commercialized. ing.

  Thus, in order to extend the cleaning nozzle in the sanitary cleaning apparatus, nozzle driving means such as a position adjusting motor is used.For example, when a position adjusting motor is used, a high torque one is required. The size of the position adjusting motor is relatively large. Therefore, an extremely large storage space is required for storage.

  On the other hand, as in Patent Document 1, the pump, the flow rate adjusting valve, the nozzle driving means, and the cleaning nozzle, which are pulsation generating means, are integrated as a unit via a support member, thereby reducing the size and size. The assembly is improved.

However, in the technique disclosed in Patent Document 1, since the nozzle driving means is housed immediately below the cleaning nozzle or the nozzle mount to which the cleaning nozzle is attached, the height of the cleaning nozzle is increased. There was a concern that the structure could not be made below the mounting height of the nozzle driving means.
Further, when a heavy nozzle driving means is attached to the side surface of the nozzle mount to which the cleaning nozzle is attached, the center of gravity of the nozzle is biased toward the driving means, which may affect the cleaning position.

JP 2004-100255 A

  It is an object of the present invention to provide a sanitary washing apparatus that can be miniaturized and made compact and that constitutes a nozzle unit with a stable washing position and can be attached to a casing.

According to the present invention, the water supply means for taking in the cleaning water from the water supply port, the pulsation generating means for adding pulsation to the cleaning water, and the flow for selectively supplying the cleaning water supplied from the pulsation generating means to the plurality of flow paths. Adjustment / flow path switching valve, cleaning nozzle for jetting cleaning water pulsated by the pulsation generating means to the human body, nozzle driving means for taking in and out the cleaning nozzle, pulsation generating means, the flow conditioning / flow path switching valve And a nozzle mount that integrally constitutes the cleaning nozzle, and a sanitary cleaning device including a casing that houses the nozzle mount, and the center of gravity of the pulsation generating means and the nozzle driving means is mounted on the nozzle mount to which the cleaning nozzle is attached. Is configured to be symmetrically attached to the axis of the cleaning nozzle in the extending direction.

According to the first invention, the water supply means for taking in the cleaning water from the water supply port, the pulsation generating means for adding pulsation to the cleaning water, and the cleaning water supplied from the pulsation generating means are selectively supplied to the plurality of flow paths. A flow control flow path switching valve, a cleaning nozzle for jetting cleaning water pulsated by the pulsation generating means to a human body, a nozzle driving means for taking in and out the cleaning nozzle, the pulsation generating means, and the flow regulating flow A sanitary washing apparatus comprising a nozzle mount that integrally forms a path switching valve and the washing nozzle, and a casing that houses the nozzle mount, wherein the pulsation is applied to the nozzle mount to which the washing nozzle is attached. The center of gravity of the generating means and the nozzle driving means is mounted symmetrically with respect to the axis in the extending direction of the cleaning nozzle.

According to the mounting structure of the pulsation generating means and the nozzle driving means, the nozzle driving means can be placed on either the left or right side with respect to the cleaning nozzle. Therefore, there is no restriction in the height direction of the nozzle, and the sanitary washing apparatus can be easily downsized and made compact. In addition, since the cleaning nozzle, the pulsation generating means, and the nozzle driving means can be integrally handled as a unit via the nozzle mount, the assembling property of the sanitary cleaning apparatus can be improved and the inspection process can be facilitated.
Further, since the center of gravity of the above-mentioned components is symmetrically attached to the casing via the nozzle mount, the rattling in the left-right direction when the cleaning nozzle is extended can be reduced, and comfortable water discharge can be provided.

Further, according to the second invention, the pulsation generating means reciprocates in the cylinder that forms part of the cleaning water supply path, and pulsates in the flow of the cleaning water by the reciprocating motion. A plunger that pumps wash water downstream of the cylinder, an electromagnetic solenoid that reciprocates the plunger, an excitation means that excites the solenoid, and a check valve that is provided in the plunger and allows the wash water to pass downstream. The direction of the reciprocating motion of the pulsation generating means is attached in parallel to the cleaning nozzle.

By attaching the vibration direction of the pulsation generating means in parallel to the extending direction of the cleaning nozzle, it is possible to minimize the lateral blur of the cleaning water discharge due to the vibration generated from the pulsation generating means.

According to a third aspect of the present invention, the pulsation generating means and the flow control / flow path switching valve are mounted on the side where the water supply means is installed with respect to the shaft in the extending direction of the cleaning nozzle.

Since the flow control flow path switching valve is mounted on the side where the water supply means is installed with respect to the shaft in the extending direction of the cleaning nozzle, the flow path from the pulsation generating means to the cleaning nozzle becomes the shortest. The pulsation added to the wash water by the means is not easily attenuated, and the user can be provided with a comfortable wash generated by adding the pulsation to the wash water.

  According to a fourth aspect of the invention, the pulsation generating means and the flow control / flow path switching valve are integrated and attached to the nozzle mount via the vibration isolating member.

  Since the pulsation generating unit and the flow control flow path switching valve are integrated, the weight increases with respect to the pulsation generating unit serving as a vibration source. For this reason, the natural frequency of the vibration source becomes larger than that when the pulsation generating unit is used alone, and a vibration suppressing effect is obtained.

  According to the aspect of the present invention, it is possible to provide a sanitary washing apparatus that can be miniaturized and made compact and that forms a nozzle unit with a stable washing position and can be attached to a casing.

  Hereinafter, a sanitary washing device according to an embodiment of the present invention will be described with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected about the same component and detailed description is abbreviate | omitted suitably.

  FIG. 1 is a style perspective view of a toilet apparatus provided with a sanitary washing device 11 according to an embodiment of the present invention. This toilet device has a toilet 10 and a sanitary washing device 11 installed thereon. The casing 12 of the sanitary washing device 11 has a toilet seat 13 and a toilet lid 14 that are pivotally supported so as to be opened and closed. The user sits on the toilet seat 14, and at the time of local cleaning, the cleaning nozzle 44 built in the casing 12 extends, and the local area is cleaned with water discharged from the cleaning nozzle 44.

  FIG. 2 is a block diagram illustrating a water channel configuration of the sanitary washing device according to the present embodiment. As shown in FIG. 2, the water channel system of the sanitary washing device includes a water supply unit 35 connected to the external water supply source 30, a heat exchanger 38, and a pulsation generator 40. Then, the cleaning water having the pulsation imparted by the pulsation generating device 40 is guided from the pulsation generating device 40 to the cleaning nozzle 44 through the flow control / flow path switching valve 42 and discharged from the cleaning nozzle 44.

  The pulsation generating means 40 will be described with reference to a sectional view showing the configuration of the pulsation generating means of FIG. As shown in FIG. 3, the pulsation generating means 40 includes a plunger 40 b slidably provided on a cylinder 40 a connected to the water supply channels 70 and 75. The plunger 40b is advanced and retracted upstream and downstream by excitation control of the electromagnetic coil 40c. The plunger 40b moves to the downstream side from the illustrated original position (plunger set position) by the excitation of the electromagnetic coil 40c. However, when the excitation of the coil disappears, the plunger 40b returns to the original position by receiving the restoring force of the lower spring 40e. At this time, the operation of the plunger 40b is buffered by the upper spring 40d.

  Since the plunger 40b has an elastomer check valve 40f inside, the plunger 40b pressurizes the washing water in the cylinder 40a and pushes it into the feed water channel 75 when moving from the plunger original position to the downstream side. At this time, since the plunger original position is constant, a certain amount of washing water is sent to the feed water channel 75. Thereafter, when returning to the original position, the cleaning water flows into the cylinder 40b through the check valve 40f, so that a certain amount of cleaning water is sent to the water supply channel 75 again by the next downstream movement of the plunger 40c. It will be. In addition, when the plunger is returned to the original position, the washing water in the downstream side of the plunger 40b, that is, in the water supply conduit 70, is drawn, so that the pulsation generator 40 periodically increases and decreases the pressure as the plunger 40b reciprocates. Fluctuating pulsation is caused, and the washing water is caused to flow through the water supply detour 75 in a pulsating state.

  FIG. 4 is an explanatory diagram for explaining the flow of washing water by the pulsation generator 40. In this case, as shown in FIG. 4, the pulsating flow generated by the pulsation generator 40 is supplied from the pulsation generator 40 to the water supply channel 75 with a pressure pulsating around the introduction water pressure Pin (primary pressure) to the pulsation generator 40, as shown in FIG. As a result, the water is sent to the cleaning nozzle 44 and discharged locally. Moreover, the washing water pressure sent downstream from the pulsation generator 40 does not become zero due to the washing water flowing into the cylinder 40a through the check valve 40f when the plunger 40b is returned to the original position as described above. This pulsation transition of the washing water pressure is reflected in the transition of the washing water flow rate. In this case, the introduction water pressure Pin, which is the center of pulsation, is regulated by the water supply unit 30, so that the pulsation can be shifted up and down with the locus shown in FIG.

  The pulsation cycle MT seen in FIG. 4 is synchronized with the excitation cycle of the pulsation generating coil 40c, and can be variously set through this excitation cycle change control. In addition, since only the excitation of the coil for reciprocating the plunger 40c is sufficient for generating the pulsating flow of the washing water, the configuration of the pulsating generating device 40 can be simplified.

  FIG. 5 shows a state in which a state in which the pulsation generator 40, the flow control flow path switching valve 42, the cleaning nozzle 44, and the nozzle driving means 50 according to the embodiment of the present invention are attached via the nozzle mount 55 is viewed from above. Yes. FIG. 6 is a perspective view showing the nozzle mount 55 according to the embodiment of the present apparatus. FIG. 7 is a schematic perspective view showing a pulsation flow adjustment unit in which the pulsation generator 40 and the flow adjustment flow path switching valve 42 according to the present embodiment are integrated.

As shown in FIG. 6, the cleaning nozzle 44 is installed along the guide rail portion 55 a provided in the nozzle mount 55. As shown in FIG. 7, the nozzle driving means 50 includes a nozzle driving motor 50a, a pinion 50b to which the rotation of the nozzle driving motor 50a is transmitted, an output gear 50c, and a cable rack (not shown). It is fixed by a screw on a flange 55f provided on 55. The cable rack is connected to the cleaning nozzle 44, and its extension length is changed by the rotation of the output gear 50c by the forward / reverse rotation of the nozzle drive motor 50a. Therefore, the cleaning nozzle 44 is driven back and forth between the storage position and the cleaning position along the guide rail portion 55a according to the rotation of the nozzle drive motor 50a.

  Further, a vibration-proof rubber (not shown) is attached to the bottom surface of the nozzle mount 55. The nozzle mount 55 is attached to the casing 12 by inserting protrusions (not shown) provided in the casing 12 into the insertion holes 55d and 55e.

As shown in FIG. 8, the pulsation generating device 40 and the flow adjustment flow path switching valve 42 are connected members 40g having the roles of the discharge side of the pulsation generation device 40 and the inflow side of the flow adjustment / flow path switching valve 42. Thus, the pulsation generation / flow adjustment unit 60 is integrally connected. In this case, the center of gravity of the pulsation generation / flow adjustment unit 60 exists on the connection member 40g and is attached to the nozzle mount 55 by the flange 40h. Thus, in addition to being integrated as a unit and increasing the mass of the vibration source, there are manufacturing advantages such as cost reduction due to the reduction in the number of members, and the apparatus can be downsized.

The pulsation generator 40 and the flow control / flow path switching valve 42 are provided with flanges 40k and flanges 42k, respectively. The flanges 40k and 42k are installed on bosses 55b and 55c on the nozzle mount 55 through vibration-proof rubber (not shown). By virtue of the vibration damping action of the vibration isolating rubber, it is possible to suppress vibration associated with the occurrence of pulsation and to suppress the generation of abnormal noise due to vibration.

  Furthermore, by attaching the pulsation generation / flow control unit 60 in parallel to the cleaning nozzle sliding direction 100, the sliding direction of the plunger 40b of the pulsation generating device 40 is parallel to the cleaning nozzle sliding direction 100. When a person cleans the local portion, it is possible to suppress blurring of discharged water due to vibration caused by the sliding of the plunger 40b described above with respect to the cleaning water discharged from the cleaning nozzle 44.

The center of gravity of the nozzle driving means 50 is set symmetrically about the cleaning nozzle sliding direction 100 with respect to the center of gravity of the pulsation / flow adjustment unit 60. As a result, when the nozzle mount 55 is installed on the casing 12 via the anti-vibration rubber, the front / rear / right / left balance is not impaired. Further, it is possible to suppress left-right blurring when the cleaning nozzle 44 is extended due to attachment.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and embodiments, and can of course be implemented in various modes without departing from the gist of the present invention. is there.
