The intake valve is integrated with the hot water tank.

Description

  The present invention relates to a human body local cleaning device, and more particularly to a human body local cleaning device that is provided in a toilet seat and that discharges hot water for human body local cleaning.

  In the human body local washing device that is provided in the toilet seat and cleans the human body part by discharging hot water from the nozzle, the water taken from an external water supply source such as public water supply is stored in the hot water tank and heated, as local washing water Supply to the nozzle. Normally, an electromagnetic valve (water intake valve) is provided between the water supply source and the hot water tank, and switching between inflow and stop of water from the water supply source to the hot water tank is performed by opening and closing control. While the local cleaning water is discharged from the nozzle and used for local cleaning, the electromagnetic valve is opened, and water flows from the water supply source into the hot water tank.

  Conventionally, the solenoid valve and the hot water tank have generally been connected using a tubular connecting member such as a hose or a pipe. In order to eliminate the connection using such a connection member and simplify the attachment of the solenoid valve to the hot water tank, in Patent Document 1, the water supply block provided with the solenoid valve is provided with a lower case (base plate). It is directly connected to the hot water tank.

Japanese Patent Laid-Open No. 11-81418

  If the connection between the water supply block including the solenoid valve and the hot water tank is performed by fixing via a base plate as in Patent Document 1, it is possible to avoid using a connection member between the solenoid valve and the water supply block. . However, because the fixture is necessary for fixing the block to the base plate, and multiple steps are required for fixing the water supply block to the base plate and connecting the water supply block and the hot water tank, the number of components can be reduced. It is not very effective in reducing or simplifying the assembly process. Moreover, it is necessary to manage the sealing performance of the connecting portion by seal inspection or the like so that water leakage does not occur at the connecting portion between the water supply block and the hot water tank.

  The problem to be solved by the present invention is that a water intake valve that switches inflow and stop of water into a hot water tank is connected to the hot water tank and an external device without requiring the use of a large number of independent parts and the execution of a large number of processes. An object of the present invention is to provide a human body local cleaning device that can be provided between a water supply source and a water supply source.

  In order to solve the above-described problems, a human body local cleaning device according to the present invention includes a nozzle that discharges local cleaning water, a hot water tank that stores and heats the local cleaning water, and supplies the nozzle to the nozzle, and an external water supply source The intake valve is configured to be integrated with the hot water tank. The intake valve is configured to switch between inflow and stop of water from the water to the hot water tank.

  Here, the human body local cleaning device is further formed integrally with the hot water tank on at least one of the upstream side and the downstream side of the intake valve, and the cold water supplied from the water supply source is heated in the hot water tank. It is preferable that an inflow water channel that is separated from the hot water and led into the hot water tank is provided, and the inflow water channel is provided with a pressure adjusting unit that adjusts a water pressure in the hot water tank.

  Further, the pressure adjusting means is provided in the inflow water channel formed on the downstream side of the intake valve, and the local washing water in the hot water tank is supplied to the outside of the human body local washing device according to the water pressure in the hot water tank. It may be a relief valve that discharges to

  And, in the hot water tank, a partition member that divides a part into which cold water flows through the intake valve and a part that heats water with a heating means, having a circulation part capable of circulating water, It is preferable to be formed integrally with the wall surface of the hot water tank.

  Furthermore, in this case, the circulation part is a gap formed between the lower end part of the partition member and the wall surface of the hot water tank, and the lower end part of the partition member is positioned below the upper end part of the heating means. It is preferable to do.

  According to the human body local cleaning device according to the above invention, since the intake valve is formed integrally with the hot water tank, independent parts such as connecting members such as hoses and pipes are used, connection by these parts, etc. Even if this process is not executed, a water intake valve is provided on the upstream side of the hot water tank. Thereby, compared with the case where a water intake valve is formed as a separate body from the hot water tank and connected to the hot water tank, the number of parts and the number of processes required for assembling the human body local cleaning device are reduced. In addition, since water does not leak between the intake valve and the hot water tank, high sealing performance can be obtained at this location, and the seal inspection of the intake valve and the hot water tank can be performed in a lump so that the time required for the seal inspection can be obtained. And can save time and effort.

  Here, the human body local cleaning device is further formed integrally with the hot water tank on at least one of the upstream side and the downstream side of the intake valve, and separates the cold water supplied from the water supply source from the hot water heated in the hot water tank. If there is an inflow channel that leads into the hot water tank and the inflow channel is equipped with pressure adjustment means that adjusts the water pressure in the hot water tank, the water pressure in the hot water tank should be kept constant by the pressure adjustment means. Can do. And since the pressure adjusting means and the intake valve and / or the hot water tank are connected by an inflow water passage formed integrally with the hot water tank, a separate part such as a hose or pipe is also provided between these parts. There is no need to use a connecting member.

  Further, the pressure adjusting means is a relief valve provided in an inflow water channel formed on the downstream side of the intake valve, and discharges the local cleaning water in the hot water tank out of the human body local cleaning device according to the water pressure in the hot water tank. In some cases, it is not the hot water heated in the hot water tank but the cold water immediately after flowing in from the water supply source that is discharged to the outside through the relief valve in order to adjust the water pressure in the hot water tank. By not releasing the already heated warm water, the heating efficiency in the warm water tank can be increased.

  And the partition member which divides the part which cold water flows into a warm water tank via an intake valve, and the part which heats water with a heating means with a circulation part which can circulate water is a warm water tank. When formed integrally with the wall surface, the flow of flowing water flowing into the hot water tank is relaxed by the partition member, and the flowing cold water is directly mixed with the already heated hot water in the same water flow. Is prevented. Thus, the local cleaning water that is sufficiently heated and has a stable temperature is discharged from the nozzle.

  Furthermore, in this case, according to the configuration in which the flow portion is a gap formed between the lower end portion of the partition member and the wall surface of the hot water tank, and the lower end portion of the partition member is positioned below the upper end portion of the heating means. The cold water that has flowed into the hot water tank is guided to the lower side of the heating means and heated while being gradually pushed upward, so that the local cleaning water discharged from the nozzle is heated to a sufficiently high and stable temperature. Is further enhanced.

The main body 2 has devices, a control unit, and the like that discharge hot water, generate hot air, and the like while being covered with a casing 4. The human body local cleaning apparatus 1 is characterized by the structure of the main body 2, particularly the structure of the portion where water flows into the hot water tank 10 that stores hot water. In the present specification, the side on which the toilet seat 3 is provided is the front, the side on which the main body 2 is provided is the rear, and the vertical direction follows the direction of gravity. And the direction orthogonal to the front-back direction and the up-down direction is defined as the width direction.

  1-4, the structure of the hot water tank 10 vicinity of the main-body part 2 is shown in the state except the casing 4. FIG. 1 and 2 are perspective views from different angles, FIG. 3 (a) is a side view of the hot water tank as seen from the water inlet side, and FIGS. 3 (b), 3 (c) and 4 are cross-sectional views at predetermined cross sections. is there.

  Each device and member constituting the main body 2 including the hot water tank 10 are fixed to the base plate 40. The toilet seat 3 is rotatably coupled to the front of the base plate 40. The main body 2 and the toilet seat 3 are attached to the toilet 100 by fixing the base plate 40 to the rear upper surface of the toilet 100.

  The nozzle pair 30 composed of the long nozzles 31 and 32 is aligned with the center position between the nozzles 31 and 32 at a position corresponding to the center of the toilet seat 3 in the width direction, and the longitudinal axis is substantially parallel to the front-rear direction. Has been placed. The nozzles 31 and 32 each have a hollow cylindrical cylinder part and a nozzle body part (which is accommodated in the cylinder in the state of each figure and is not shown) that is movably held in the hollow part of the cylinder part. . The local washing water supplied from the hot water tank 10 is discharged from the vicinity of the tip of the advanced nozzle body, and the human body part is washed. The two nozzles 31 and 32 are selectively used depending on the body part to be cleaned and the difference in purpose (for example, for anal cleaning and for so-called bidet cleaning). The front end portions 31 a and 32 a of the cylinder portions of the nozzles 31 and 32 are held by a base front end surface 41 erected on the front end portion of the base plate 40, and the base end portions 31 b and 32 b are centered in the vertical direction of the hot water tank 10. It is fixed to the hot water tank 10 at a position above the position.

  The hot water tank 10 is configured as a hollow container, is supplied with water from a water supply source outside the human body local washing apparatus 1 such as a public water supply, stores the water, and is heated by the heater 80. The heater 80 includes a cylindrical heating unit 81 such as a ceramic heater and temperature measuring means such as a thermistor. The heater 80 is inserted into the hot water tank 10 to store water stored in the hot water tank 10 with a predetermined amount. Heating is controlled at the temperature. The heating part 81 of the heater 80 is provided below the central part in the vertical direction of the hot water tank 10.

The hot water tank 10 is made of a resin such as polypropylene. The hot water tank 10 is composed of two members divided in the width direction, that is, a water inlet side tank member 11 and a water discharge side tank member 12. Edges 11 a and 12 a projecting outward are provided at the edge of each opening of the water inlet side tank member 11 and the water discharge side tank member 12. And the edge parts 11a and 12a are welded mutually, and the water-inlet side tank member 11 and the water discharge side tank member 12 are joined in the opening part, and it is set as the hollow warm water tank 10. FIG. The surface formed by the welded portion is substantially parallel to the vertical direction.

  A water supply pipe 52, an electromagnetic valve (water intake valve) 51, a relief valve 53, and an inflow water channel 54 are formed in the water inlet side tank member 11 in order to take in water from an external water supply source. The structure of the part provided with these members is shown in particular detail in FIG.

  The water supply pipe 52 is a tubular member that protrudes outward in the width direction from the water inlet side tank side wall 11 b that is the side wall of the water inlet side tank member 11, and the hollow portion communicates with the space inside the water inlet side tank member 11. . The water supply pipe 52 is connected to an external water supply source. And the water supplied from the water supply source passes into the hot water tank 10 through the water supply port 52a provided as the base end portion of the water supply pipe 52 (joint portion between the water supply pipe 52 and the water inlet side tank side wall 11b). Inflow. Note that the tip of the water supply pipe 52 protrudes to the outside of the base side surface 42 through a through-hole provided in the base side surface 42 so that the connection work to a water supply source using a joint or the like can be easily performed.

  The inflow water channel 54 includes a water channel partition wall 54 a formed integrally with the water inlet side tank member 11 so as to partition a space in the water inlet side tank member 11, and a wall surface of the water inlet side tank member 11. As a space between the two, the hot water tank 10 is provided integrally with the hot water tank 10. The water channel partition 54 a is continuous with the wall surface of the water supply pipe 52, and the space in the inflow water channel 54 communicates with the hollow portion of the water supply pipe 52. Thereby, all the water supplied from the water supply source through the water supply pipe 52 flows into the hot water tank 10 through the inflow water channel 54.

  A solenoid valve 51 is provided in the middle of the inflow water channel 54. The electromagnetic valve 51 is controlled to open and close in response to an electric signal. When discharging the local cleaning water from the nozzles 31 and 32, the electromagnetic valve 51 is opened, and the hot water tank 10 is supplied from the water supply source through the inflow water channel 54. And water flows in. When the solenoid valve 51 is in the closed state, the flow of water is interrupted in the middle of the inflow water channel 54, and the inflow of water from the water supply source to the hot water tank 10 is stopped.

  The solenoid valve 51 is formed integrally with the hot water tank 10. That is, the valve box 51a made of resin on which the valve seat 51b is formed is formed integrally with the wall surface of the inflow-side tank member 11 by integral molding using a mold or the like. A valve body unit 51e having a valve body 51c, a solenoid 51d, etc. formed separately from the valve box 51a is disposed so as to cover the valve box 51a, and is fixed to the valve box 51a by screwing. ing.

  A relief valve 53 is further provided on the downstream side of the solenoid valve 51 in the midway portion of the inflow water channel 54. The relief valve 53 is a valve whose opening amount can be adjusted by using the spring member 53c. The relief valve 53 is opened greatly as the water pressure in the hot water tank 10 increases due to the inflow of water into the hot water tank 10, and the relief valve 53 in the hot water tank 10 is opened. Water is thrown into the toilet 100 through the relief port 53d. Thereby, the relief valve 53 plays the role of keeping the water pressure in the hot water tank 10 constant.

  The relief valve 53 is also formed integrally with the hot water tank 10. That is, similarly to the electromagnetic valve 51, the valve box 53 a having the valve seat 53 b is formed integrally with the water-inlet side tank member 11. A valve body unit 53f having a valve body 53e, a spring member 53c, and a relief port 53d is fixed to the valve box 53a. Note that the relief port 53d is provided so as to protrude in the horizontal direction or below it so that the water discharged from the relief port 53d does not scatter.

  The water discharge side tank member 12 is connected to the base end portions 31b and 32b of the nozzles 31 and 32 at a portion above the central portion in the vertical direction. A flow path switching valve 60 is provided between the space in the water discharge side tank member 12 and the nozzles 31 and 32. The flow path switching valve 60 plays a role of selecting one of the nozzles 31 and 32 and causing the local cleaning water in the hot water tank 10 to flow out, and adjusting the outflow amount.

  Furthermore, a partition member 70 including a first partition plate 71 and a second partition plate 72 is provided in the space inside the water inlet side tank member 11 and the water discharge side tank member 12 as shown in FIG. Yes. These partition plates 71, 72 have a flat plate shape inclined obliquely downward toward the rear, and are integrally formed from the front wall surfaces 11 c, 12 c of the water inlet side tank member 11 and the water discharge side tank member 12. It is extended. The lower end edges 71 a and 72 a of the two partition plates 71 and 72 are not in contact with the bottom surface of the hot water tank 10, and a gap G is formed between the bottom surface of the hot water tank 10 and functions as a circulation part through which water can flow. Has been. The lower end edges 71 a and 72 a of the partition plates 71 and 72 are disposed below the upper end portion 81 a of the heating unit 81 of the heater 80.

  Further, in the human body local cleaning device 1 according to the present embodiment, the heating unit 81 of the heater 80 is provided below the central portion in the vertical direction of the hot water tank 10, and the base end portions 31 b and 32 b of the nozzles 31 and 32 are hot water. The tank 10 is provided above the center in the vertical direction. Due to this configuration and the configuration of the partition member 70, the hot water heated by the heating unit 81 and raised to the position of the nozzle base end portions 31b and 32b is sufficiently high from the nozzles 31 and 32 at a stable temperature without unevenness. It can be discharged.

  In a conventional general human body local cleaning apparatus, an electromagnetic valve is formed separately from the hot water tank, and the hot water tank and the electromagnetic valve are connected by a tubular connecting member made of a separate body such as a hose or a pipe. . On the other hand, in the human body local cleaning apparatus 1 according to the present embodiment, the electromagnetic valve 51 is integrally formed in the hot water tank 10. Thereby, the connection member for connecting between the solenoid valve 51 and the hot water tank 10 becomes unnecessary, and the process for connecting them is also unnecessary. In addition to the connection member, the electromagnetic valve 51 and the hot water tank 10 are connected via other parts of the human body local cleaning device 1 such as a fixing member for fixing the electromagnetic valve 51 to the base plate 40 as in the case of Patent Document 1. There is also no need for a member for fixing them together. Thus, the structure of the site | part between the hot water tank 10 and the solenoid valve 51 is very simple.

  In addition, since a connecting member such as a hose or a pipe is not used between the hot water tank 10 and the electromagnetic valve 51, high sealing performance against water leakage is exhibited between the hot water tank 10 and the electromagnetic 51 valve. Furthermore, since the hermetic inspection, which has conventionally been performed separately for the hot water tank and the electromagnetic valve, can be performed collectively with the hot water tank 10 and the electromagnetic valve 51, the time and cost required for the inspection process are greatly reduced. .

  In the human body local cleaning device 1, not only the electromagnetic valve 51 but also the water supply pipe 52, the relief valve 53, and the inflow water channel 54 are formed integrally with the hot water tank 10. This eliminates the need for connecting members such as hoses and pipes between any of the water supply source, the electromagnetic valve 51, the relief valve 53, and the hot water tank 10. Thereby, the parts cost and assembly cost of the human body local cleaning apparatus 1 are further reduced. Further, the airtight inspection can be performed all at once for the water flow path from the water supply pipe 52 to the hot water tank 10. In addition, in the water discharge side tank member 12, if the connection part to which the base end parts 31b and 32b of the nozzles 31 and 32 are connected and the flow path switching valve 60 are also formed integrally with the water discharge side tank member 12, an airtight inspection is performed. Can be collectively performed on the entire water flow path from the water supply pipe 53 to the nozzles 31 and 32.

  In the above-described human body local cleaning apparatus 1, the inflow water channel 54 is formed, so that unheated cold water flowing from the water supply source is filled in the hot water tank 10 and heated with the heater 80. Are separated by a water channel partition wall 54a. Since the relief valve 53 is provided along with the electromagnetic valve 51 on the inflow water passage 54, when adjusting the water pressure in the hot water tank, the relief valve 53 passes through the inflow water passage 54, not the hot water heated by the heater 80. Thus, the cold water immediately after flowing into the hot water tank 10 can be selectively discharged. Thereby, the fall of the heating efficiency by the warm water already heated being discharged | emitted from the relief valve 53 is suppressed.

  Further, in the above-described human body local cleaning device 1, the partition member 70 is provided, so that the water flow of the cold water flowing into the hot water tank 10 from the water supply pipe 52 via the electromagnetic valve 51 is relieved, and the cold water and the heater 80 The hot water heated by the heating unit 81 is not directly mixed. Thereby, the temperature of the local cleaning water discharged from the nozzles 31 and 32 is sufficiently high and stable. Such a role of the partition member 70 is exhibited even when the inflow path of the cold water is not defined by the inflow water path 54, but as described above, the cold water passes through the narrow inflow water path 54 and enters the hot water tank 10. When introduced, the cold water is guided into the hot water tank 10 with a high water flow and directivity, so that the partition member 70 effectively reduces the water flow and directivity.

  Furthermore, in the partition member 70 described above, the lower end edges 71 a and 72 a of the partition plates 71 and 72 are positioned below the upper end portion 81 a of the heating unit 81, thereby passing through the inflow water channel 54 and more than the partition member 70. The cold water flowing downward is weakened by the partition member 70 and gradually rises through the gap G and is heated by the heating unit 81 while being gradually mixed with the already heated hot water. The heated hot water is supplied to the base end portions 31b and 32b of the nozzles 31 and 32 provided above the center of the hot water tank 10 so as to be gradually pushed upward. Thereby, the temperature of the local cleaning water discharged from the nozzles 31 and 32 is higher and more stable.

  In view of the role of the partition member 70, the distance between the two partition plates 71 and 72 is preferably small and more preferably not provided. Since the hot water tank 10 is comprised from the side tank member 12, it arises unavoidable. Even if the partition plate is not provided in both the water inlet side tank member 11 and the water discharge side tank member 12, even if only one side is provided, a certain degree of effect is exhibited.

  As described above, when the electromagnetic valve 51, the water supply pipe 52, the relief valve 53, the inflow water channel 54, and the partition plates 71 and 72 are formed integrally with the hot water tank 10, the hot water tank 10 enters the water as described above. It is advantageous in manufacturing that the side tank member 11 and the water discharge side tank member 12 are divided into two members. The water inlet tank member 11 and the water discharge side tank member 12 provided with the respective members to be integrally formed are separately formed by molding, and then joined together in the width direction, so that the hot water tank 10 can be simply formed. It is because it can form. Furthermore, it is preferable that the solenoid valve 51 and the relief valve 53 are provided in parallel with each other from the viewpoint of facilitating molding using the split mold. The water supply pipe 52 and the water channel partition wall 54a are preferably parallel to the partition plates 71 and 72.

(Other embodiments)
The human body local cleaning device 1 according to the above embodiment can be modified as follows.
(1) In the above-described embodiment, the relief valve 53 is provided on the downstream side of the solenoid valve 51 as a pressure adjusting means for adjusting the water pressure in the hot water tank 10, but instead of the relief valve 53, the solenoid valve A regulator may be provided on the upstream side of 51. The regulator is a pressure adjusting means capable of continuously changing the pressure of water passing therethrough, and can keep the pressure in the hot water tank 10 constant without throwing water outside. Although the regulator is a pressure adjustment means that is more expensive than the relief valve, it can be suitably employed from the viewpoint of water saving. When a regulator is provided on the upstream side of the solenoid valve 51, the water supply pipe 52 may be connected to the water supply source via the regulator. Then, it is possible to connect the regulator and the electromagnetic valve 51 without using a connecting member such as a hose or a pipe.

  In the above, for convenience of explanation, the water supply pipe 52 and the inflow water channel 54 are handled as separate members. However, the water supply pipe 52 is formed integrally with the hot water tank 10, and cold water supplied from a water supply source is used as the hot water tank 10. It can be regarded as a part of the inflow water channel 54 in the sense that it is separated from the hot water heated inside and led into the hot water tank 10. An inflow water channel 54 is formed on at least one of the upstream side and the downstream side of the electromagnetic valve 51, and pressure adjusting means is provided in the inflow water channel 54 (in the case of a relief valve, on the downstream side of the electromagnetic valve 51, in the case of a regulator, the electromagnetic It is no longer necessary to provide a connecting member such as a hose or pipe between the solenoid valve 51, the hot water tank 10, and the pressure adjusting means. Furthermore, a flow rate adjusting valve may be appropriately provided upstream of the electromagnetic valve 52 and the pressure adjusting means.

(2) The partition member 70 does not need to be composed of the partition plates 71 and 72 having the shape and arrangement as described above. The partition member 70 divides a region where cold water flows and a region where hot water exists, and water flows. What is necessary is just to have the distribution part which can do. However, the degree of the effect of preventing the mixing of cold water and hot water depends on the specific configuration of the partition member.

(3) For the purpose of simplifying the installation part of the solenoid valve 51 to the hot water tank 10, the inflow water channel 54 and the partition member 70 are required as long as the solenoid valve 51 has a configuration integrally formed with the hot water tank 10. May not necessarily be provided, and even if provided, may not be formed integrally with the hot water tank 10. Further, the relief valve 53 does not need to be formed integrally with the hot water tank 10 and does not need to be provided in the middle portion of the inflow water channel 54 so that only cold water can be discharged.

(4) In the above-described embodiment, the hydraulic nozzles 31 and 32 are provided which are composed of a cylinder part and a nozzle body part, and the nozzle body part moves forward and backward in the cylinder by the water pressure of the local cleaning water. However, instead of the hydraulic nozzles 31 and 32, it is also possible to employ an electric nozzle that does not have a cylinder and is driven by a motor to move forward and backward. In this case, a water supply adapter that is fixed to a guide member that holds the nozzle so as to be able to advance and retract and serves as an inlet of water for supplying cleaning water to the nozzle is provided above the center in the vertical direction of the heat retaining tank 10. What is necessary is just to connect to a water inlet.

As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention. In addition, although not deviating from the embodiment of the present invention, if the configuration of each element other than the electromagnetic valve 51 employed in the above embodiment is applied alone or in combination, the effects of each configuration can be enjoyed. Can do. Examples of such a configuration include the following.
(I) An inflow channel formed integrally with a hot water tank on at least one of the upstream side and the downstream side of the solenoid valve, and separates the cold water supplied from the water supply source from the hot water heated in the hot water tank and guides it into the hot water tank And a pressure adjusting means for adjusting the water pressure in the hot water tank is provided in the inflow water channel.
