Description

[Technical field]

[0001] The present invention relates to a posterior cleaning device capable of cleaning a user's anus with water or hot water during toileting, and relates to a posterior cleaning device of a type that can be carried by the user. [Background technology]

[0002] The use of a warm water washing toilet seat allows the patient to cleanse the anus without having to wipe it with toilet paper, and is therefore extremely useful for patients with anal diseases such as hemorrhoids. However, there are quite a few public toilets that are used by an unspecified number of people that are not equipped with warm water washing toilet seats. Also, in quiet, remote areas (so-called "rural areas") away from urban areas, the prevalence of warm water washing toilet seats is still not high. Therefore, when patients with anal diseases use public toilets or live in quiet, remote areas, they cannot use a warm water washing toilet seat when using the toilet outside of their own home, and are forced to wipe their anus with toilet paper. This can hinder the healing of anal diseases.

[0003] In addition, water and electrical equipment are essential to install a warm water washing toilet seat, but in scenic areas where it is mandatory to maintain a natural state, for example, it can be difficult to install water and electrical equipment. Therefore, there is a demand for a portable type of rear washing device that can wash the user's anus with water or hot water when using the toilet. However, a portable posterior washer that can reliably spray water or hot water onto the user's anus to clean it without causing stress to the user and that can be easily carried around has not yet been proposed.

[0004] As an example of prior art, there is a portable bottom washer that has a structure similar to that of a commercially available household spray bottle and is configured to spray liquid from the nozzle without diffusing (see Patent Document 1). However, for example, when using the toilet while sitting on the toilet, the space under the user's buttocks is small and limited, and it is difficult to place a device the same size as a household sprayer in such a small and limited space. Similarly, in a small, confined space, it is extremely difficult to adjust the position of the spray-type cleaning device of the prior art (Patent Document 1) so that the water sprayed from the cleaning device is aimed at the user's anus, and there is a risk that part of the spray bottle will interfere with the user's buttocks. Furthermore, the water sprayed into the anus will likely bounce back with dissolved feces and stick to the cleaning device placed in the space under the user's buttocks, creating an unsanitary and dirty environment.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 11-18995 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been proposed in consideration of the problems with the conventional technology described above, and aims to provide a portable bottom washer that can reliably spray water or hot water into the user's anus to clean it without causing stress to the user, and that can be easily carried around. [Means for solving the problem]

[0007] The portable posterior cleansing device (10) of the present invention comprises: A container (1) capable of storing water or hot water therein; A lid portion (2) that can be engaged (screwed) with the opening of the container (1) to close it; A pump unit (3) for pressurizing the inside of the container (1), The device includes a pump discharge pipe (4A) provided on the discharge side of a pressurizing pump (4) provided in the pump section (3), and a spray pipe (5) extending from a region in the container (1) in which cold or hot water is stored to an outlet section (3A) of the pump section (3). An on-off valve (6) is interposed in the spray pipe (5), and a valve operation button (7) for operating the on-off valve (6) is provided. A pump discharge pipe (4A) and a spray pipe (5) of the pump portion (3) pass through the cover portion (2), and a seal material is disposed to make the pass-through portion watertight; The toilet has a hose (8) connected to the outlet portion (5A) of the spray pipe (5) at the outlet portion (3A) of the pump portion (3), and the hose (8) is made of a flexible and water-impermeable material and is longer than the length from a position beside the toilet bowl (20) through the crotch (UA) of the user (U) to the anus (UB).

[0008] In the portable posterior cleansing device (10) of the present invention, It is preferable that a curved portion (8B) having a curvature radius of about 2 to 5 cm is formed near the hose tip (8A) on the side opposite to the side connected to the outlet portion (5A) of the spray pipe (5) of the pump portion (3) of the hose (8). In this case, it is preferable that the hose tip 8A in the vicinity of the curved portion 8B has an inner diameter (caliber) smaller than that of other regions of the hose 8. Alternatively, it is preferable that a spray nozzle is attached to the hose tip 8A in the vicinity of the curved portion 8B.

[0009] The method of using the portable posterior cleansing device (10: the portable posterior cleansing device according to any one of claims 1 and 2) is as follows: After using the toilet ("YES" in step S2), a step (step S3) is performed in which the curved portion (8B) of the hose (8) or a region of the curved portion (8B) closer to the pump portion (3) is pinched with fingers, and the hose tip (8A) is brought closer to the anus (UB) of the user (U) via the crotch (UA) of the user (U); a step (step S4) of operating (pressing) the valve operating button (7) to open the on-off valve (6) and pushing the water from within the container (1) by the pressure within the container (1) so that the water is sprayed from the hose tip (8A); a step (S5) of adjusting the collision position of the water (hot water) jetted from the tip of the hose (8A) by pinching the curved portion (8B) or a portion closer to the pump (3) than the curved portion (8B) so that the jet of water impinges on the anus (UB); Once the anus (UB) has been cleansed with the jet (cold or hot water) from the hose tip (8A) (step S6 is "YES"), the method includes a step (step S7) of operating the valve operation button (7) to close the on-off valve (6) and terminate the jet from the hose tip (8A).

[0010] The manufacturing method of the portable posterior cleansing device (10: the portable posterior cleansing device according to any one of claims 1 and 2) is as follows: A process of processing the outlet portion (5A) of the injection pipe (5) of the pump portion (3) so as not to diffuse cold or hot water; a step of connecting the hose (8) to an outlet portion (5A) of the injection pipe (5) of the pump portion (3); forming a curved portion (8B) in the hose (8); The method is characterized by including a step of reducing the inner diameter of the hose at the hose tip (8A). Effect of the Invention

[0011] According to the present invention having the above-mentioned configuration, by simply performing the operations of pressurizing the pump (3), arranging (routing) the hose (8) in a path that runs from a position beside the toilet bowl (20) through the crotch (UA) of the user (U) to the vicinity of the anus (UB) of the user (U), adjusting the position where the water or hot water impinges, and pressing the pump operation button (7), the anus (UB) of the user (U) can be cleaned and washed when using the toilet, even if the toilet seat is not equipped with a warm water washing function, and without using toilet paper. According to the present invention, only the hose (8) is positioned below the buttocks of the user (U), and by positioning the hose (8) below the buttocks via the crotch (UA) of the user (U), the spray direction can be easily adjusted so that water or hot water is sprayed toward the anus even in the narrow and limited space below the buttocks. In addition, since the surface area of ​​the hose (8) is much smaller than that of a spray bottle or the like, there is little possibility that the hose (8) will interfere with the buttocks or anus (UB) of the user when adjusting the direction of the water or hot water spray, or that the water or hot water will hit the anus and splash back onto the hose (8). Even if the water or hot water does splash onto the hose (8), the hose (8) is easy to wash, so it can always be kept clean. Furthermore, since the hose (8) is made of a flexible and water-impermeable material, the hose (8) can be easily arranged (wired) even along a curved path from a position beside the toilet bowl (20) through the crotch (UA) of the user (U) to the vicinity of the anus (UB) of the user (U).

[0012] Here, in order to make a jet of water hit the anus (UB), it is necessary to spray the jet straight up from the tip of the hose. However, in the inventor's research, it was found that it was difficult to spray the jet straight up from the tip of the hose by holding a flexible hose with the fingers of one hand. On the other hand, if a curved portion (8B) is provided near the hose tip (8A), it becomes extremely easy to position the tip side of the curved portion (8B) so that it faces upward, and it becomes easy to spray water or hot water straight up from the hose tip (8A).

[Figure 4] 4 is a flowchart showing a procedure for use in the illustrated embodiment. [Diagram 5] 4 is a flowchart showing a manufacturing procedure in the illustrated embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In Figure 1, the portable posterior washing device, generally designated by the reference symbol 10, comprises a container 1 capable of storing water or hot water W therein, a lid portion 2 that can engage (screw) with the opening of the container 1 to close it liquid-tight, a pump portion 3 that pressurizes the inside of the container 1, and a hose 8. The container 1 may be of any size so long as it is portable, and for example, a container made of polyethylene terephthalate (a so-called "PET bottle") can be used. It is preferable that the container has a size necessary and sufficient to store the amount of water required for buttocks (anus) washing, for example, a capacity of about 1 liter. And, since it is difficult to deform when pressurized, for example, a PET bottle for strong carbonated water is suitable. If it is a PET bottle that is difficult to deform, its bottom will not expand even when pressurized, and even if the container 1 is placed on the floor of the toilet, there is no risk of it (the container 1 made of a PET bottle that is difficult to deform) tipping over when pressurized. Furthermore, it is preferable that the container 1 has a degree of stability so that it does not tip over when placed next to the toilet bowl 20 (see Figs. 2 and 3).

[0015] 1, the pump section 3 has a pressurizing pump 4 and a spray pipe 5. The pressurizing pump 4 is operated by reciprocating an operating handle 4B. A pump discharge pipe 4A is provided on the discharge side of the pressurizing pump 4, and the pump discharge pipe 4A passes through the lid section 2, with its tip disposed inside the container 1. One end of the injection pipe 5 is disposed in the area in the container 1 where cold or hot water W is stored, and extends through the lid 2 to the outlet 3A of the pump section 3. An opening / closing valve 6 is disposed in the area near the outlet 3A (of the pump section 3) on the other end side of the injection pipe 5. A valve operation button 7 for operating the opening / closing valve 6 is provided. A pump discharge pipe 4A and a spray pipe 5 penetrate the lid 2 of the container 1, and a sealing material (not shown) is placed at the penetration point to make it airtight and liquidtight, so that the water W (or hot water) in the container 1 does not leak from the penetration point and the pressure inside the container 1 does not leak out of the container 1. Although not clearly shown in the figure, the on-off valve 6 and the valve operation button 7 are configured so that when the on-off valve 6 is closed and the valve operation button 7 is pressed once, the on-off valve 6 is placed in an open state, and when the on-off valve 6 is open and the valve operation button 7 is pressed once, the on-off valve 6 is placed in a closed state. It should be noted that the pump section 3 may be a commercially available product that has been modified.

[0016] One end of the hose 8 is connected to the outlet 5A of the injection tube 5 at the outlet 3A of the pump section 3, and the user U uses the hose 8 by pinching the other end (tip) of the hose 8 and bringing it close to the anus UB (FIGS. 2 and 3) of the user U. There are no particular limitations on the material of the hose 8 as long as it is made of a flexible and water-impermeable material, and for example, a silicone hose can be used. The length of the hose 8 is set to be longer than the length of a curved path that runs from the position beside the toilet 20 where the cleaning device 10 is placed, through the crotch UA of the user U, to the vicinity of the anus UB of the user U. The length of the hose 8 varies depending on the height and arm and leg lengths of the user U, but is set within the range of 1 m ± 15 cm, for example. Here, if the length of the hose 8 is less than 85 cm, the hose tip 8A will not reach the area near the anus UB of the user U, and the hose tip 8A will be too far away from the anus UB, making it difficult for the water (hot water) sprayed from the hose tip 8A to reach the anus UB of the user U. On the other hand, if the length of the hose 8 is set to 115 cm or more, it will be bent and positioned in the space below the anus UB of the user U, and there is a risk that the water will hit the anus UB of the user UB and splash back with dissolved feces, causing it to become unsanitary.

[0017] With reference to FIG. 1, the configuration and function of the area near the tip 8A of the hose 8, in other words, the area opposite the side of the hose 8 connected to the outlet 5A of the spray pipe 5, will be described. The hose 8 is formed with a curved portion 8B curved with a radius of curvature of about 2 to 5 cm near the tip 8A. By providing such curved portion 8B, it becomes easier to adjust the water or hot water sprayed from the hose tip 8A so that it hits the anus UB of the user U who is holding the hose 8. Here, in order to make a jet of water or hot water collide with the anus UB, it is necessary to spray a jet of water from the hose tip 8A toward the anus UB, from below toward the anus UB (a jet of water directed straight up). Research by the inventors has shown that pinching a flexible hose with the fingers of one hand to direct the jet from the hose tip straight up makes the shape of the hose unstable due to the flexibility (or pliability) of the hose 8, and it is difficult to accurately adjust the direction of the jet of water sprayed from the hose tip 8A. However, if the curved portion 8B is provided, it becomes extremely easy to arrange the hose tip 8A so that it faces upwards by pinching the curved portion 8A or a portion of the hose 8 near the curved portion 8B, and therefore the water or hot water sprayed from the hose tip 8A can be easily sprayed straight up, and the water or hot water sprayed from the hose tip 8A can be adjusted to collide with the anus UB. In the illustrated embodiment, as described later with reference to Fig. 5, the curved portion 8B is formed by wrapping a fibrous member (e.g., "octopus thread") around the hose and solidifying it with an epoxy resin adhesive. Therefore, the direction of the hose tip 8A can be easily adjusted by pinching the curved portion 8A or its vicinity, and by pinching the curved portion 8B, it is easy to adjust the water (or hot water) sprayed from the hose tip 8A to hit the anus UB.

[0018] Although not shown in Figure 1, the hose tip 8A near the point where the curved portion 8B is formed is, for example, heated and stretched to reduce the inner diameter of the hose, thereby increasing the speed of the jet of water (or hot water) W sprayed therefrom. However, it is also possible to not reduce the inner diameter of the hose at the hose tip 8A and to attach a nozzle (not shown) to the hose tip.

[0019] When using the portable posterior cleaning device 10 shown in Fig. 1, the hose 8 is routed from a position beside the toilet 20 on which the portable posterior cleaning device 10 is placed, through the crotch UA of the user U, to below the anus UB, and the curved portion 8B is pinched to adjust the collision position of the water or hot water W (adjust so that the collision position is the anus UB).Then, the handle 4B of the pressurizing pump 4 is operated (the handle 4B is pushed back and forth several times to cause reciprocating motion) to pressurize the inside of the container 1, and the valve operating button 7 is operated to open the opening / closing valve 6, and the pressurized water or hot water W in the container 1 flows through the spray pipe 5 and hose 8, and is sprayed from the reduced diameter hose tip 8A. By such a simple operation, even if the toilet does not have a warm water washing toilet seat, the anus UB of the user U can be cleanly washed with water or hot water when using the toilet without using toilet paper. Furthermore, if the hose 8 is made of a flexible, non-permeable material, it can be easily routed along a curved path from a position next to the toilet 20 through the crotch UA of the user U to the vicinity of the anus UB. Here, since the surface area of ​​the hose 8 is far smaller than that of a spray bottle or the like, when the water (hot water) sprayed into the anus UB hits the buttocks or the vicinity of the anus UB of the user U, there is little chance that the rebounded water or hot water will splash onto the hose 8, and even if the water or hot water does splash onto the hose 8 (the water or hot water that hits the vicinity of the anus UB), the hose 8 can be easily washed. A specific washing procedure using the portable bottom washing device 10 will be described later with reference to FIG.

[0020] When using the portable posterior cleaning device 10 shown in Fig. 1, the portable posterior cleaning device 10 is placed on the side of the toilet bowl 20 as shown in Fig. 2 and Fig. 3. In Fig. 2 and Fig. 3, the portable posterior cleaning device 10 is shown with a solid line, the toilet with a dashed line, and the user U with a dashed line. To avoid complication, the user U is not shown in Fig. 3. In Fig. 2, a user U sits on a toilet seat 21 and grasps (with one hand) a curved portion 8B near a tip 8A of a hose 8. Here, the hose 8 extends from the container 1 and the pump unit 3 of the cleansing device 10, and is routed through (passes through) the crotch UA of the user U and the toilet seat 21 so that the tip 8A is located below the anus UB. 2, only the vicinity of the tip 8A of the hose 8 extending from the main body of the cleansing device 10 exists in the narrow, limited space below the anus UB inside (below) the toilet seat 21. The user U can easily adjust the position of the hose tip 8A in the space. 3, reference numeral 7 denotes a valve operating button for starting or stopping the spray of cold or hot water from a hose tip 8. Reference numeral 22 in FIGS. Although not shown in Figs. 2 and 3, the user U can also use the portable bottom cleaning device 10 while holding it in front of his / her stomach or on his / her knees.

[0021] Next, mainly with reference to FIG. 4, a method of using (procedure for using) the portable bottom washing device 10 according to the illustrated embodiment will be described. Here, the portable bottom washing device 10 according to the illustrated embodiment may be carried in an assembled state as shown in FIG. 1, or it may be disassembled and carried into the container 1 and a part in which the lid 2 and hose 8 of the container 1 are attached to the pump section 3 (a collective term for the pressurizing pump 4, pump discharge pipe 4A, pump operation handle 4B, spray pipe 5, on-off valve 6, and valve operation button 7). In the case where the pump unit 3 is disassembled into the container 1 and the part with the lid 2 and hose 8 of the container 1 attached thereto, and the container 1 itself is carried out, a procedure not shown in Fig. 4 is carried out before step S1. That is, the procedure is to fill the container 1 with water W (or hot water), screw the lid 2 onto the container 1, insert the pump discharge pipe 4A and the injection pipe 5 into the container 1 (through the lid 2) and assemble it as shown in Fig. 1, and to pressurize the inside of the container 1 by pressing the handle 4B of the pressurizing pump 4 several times. However, the procedure of pressurizing the inside of the container may be carried out after using the toilet and before washing the bottom. The container 1 is filled with water W (or hot water) to, for example, about half the capacity.

[0022] In FIG. 4, in step S1, when using the toilet, the portable posterior cleansing device 10 shown in FIG. 1 is placed on the side of the toilet 20 as shown in FIGS. After relieving oneself, step S2 judges whether the user has finished relieving himself / herself. If the user has not finished relieving himself / herself, the process loops to "NO" in step S2. If the user U has finished using the toilet, the result of the determination in step S2 is "Yes", and the process proceeds to step S3. In step S3, the user U holds the curved portion 8B of the hose 8 or the area of ​​the curved portion 8B closer to the pump portion with his / her fingers, and moves the hose tip 8 through the crotch UA to approach the anus UB (routing the hose 8). Then, the process proceeds to step S4. Although not shown in FIG. 4, the user U operates the handle 4B of the pressurizing pump 4 to pressurize the inside of the container 1 at a stage prior to step S4. In step S4, the valve operation button 7 is pressed. When the valve operation button 7 is pressed while the on-off valve 6 is closed, the on-off valve 6 is opened, and the cold or hot water W in the container 1 is pushed out by the pressure in the container 1. Then, the cold or hot water W flows through the hose 8 and is sprayed from the hose tip 8A. When water W (hot water) is sprayed from the hose tip 8A and strikes the anus UB or its surroundings, in step S5, the user U adjusts how he or she grips the curved portion 8B of the hose 8 or the portion closer to the pump than the curved portion 8B, the direction of the jet, and the spray position (impact position) so that the jet strikes the anus UB reliably. Then, the process proceeds to step S6.

[0023] In Fig. 4, in step S6, the user U judges whether the anus UB has been washed after using the toilet. Washing continues until the user U judges that a predetermined amount of water (hot water) hits the anus UB and the anus UB has been sufficiently washed (a loop of NO in step S6). If the user U judges that "the anus UB has been cleaned" by the jet (cold or hot water) from the hose tip 8A ("YES" in step S6), the process proceeds to step S7. In step S7, the user U presses the valve operation button 7 to close the on-off valve 6, thereby cutting off (terminating) the jet flow from the hose tip 8A. In the next step S8, moisture around the anus is wiped off using toilet paper etc. However, step S8 (the procedure of wiping moisture around the anus using toilet paper etc.) can be omitted. When step S8 is completed, the user U takes the portable bottom cleansing device 10 and leaves the toilet. When the portable bottom washing device 10 according to the illustrated embodiment is disassembled into the part having the lid 2 of the container 1 and the hose 8 attached to the pump unit 3 and the container 1, after step S8, the lid 2 is unscrewed from the container 1, and the part having the lid 2 of the container 1 and the hose 8 attached to the pump unit 3 and the container 1 are disassembled and carried. Although not shown in FIG. 4, a procedure for cleaning the hose 8 and the like may be performed after step S8.

[0024] Next, a manufacturing method for the portable bottom washing device 10 according to the illustrated embodiment will be described with reference to FIG. A manufacturing method will be described for the portable bottom washing device 10 described in Figures 1 to 4 in the case where the pump section 3 has a simple pump (corresponding to the pressurizing pump 4, pump discharge pipe 4A, and pump operation handle 4B in Figure 1) and a discharge pipe (spray pipe 5) having an on-off valve 6 and a valve operation button 7. In this manufacturing method, it is possible to modify and use a commercially available product as the pump portion 3, and the following description will be given assuming that a commercially available product is modified and used. In the description, the reference numerals in FIG. 1 are used to denote the respective parts. When using a modified version of a commercially available product as the pump section, there is no need for a mechanism to diffuse the water or hot water to be sprayed at the outlet 5A of the spray pipe 5. Conversely, the outlet 5A of the spray pipe 5 must be configured so that the water (hot water) to be sprayed does not diffuse. In addition, the pump discharge pipe 4A and the spray pipe 5 must be passed through the lid 2 of the container 1 to communicate the pump discharge pipe 4A with the inside of the container 1 and to supply water or hot water W in the container 1 to the spray pipe 5. Furthermore, it is necessary to connect a hose 8 to the outlet portion 5A of the injection pipe 5. Also, it is necessary to fabricate a curved portion 8B near the tip 8A of the hose 8, and in addition, the inner diameter of the hose at the hose tip 8A must be reduced.

[0025] FIG. 5 shows the procedure for manufacturing the illustrated portable posterior cleansing device, which includes a processing step (step S11) for carrying out the above-mentioned processing required for each component, and an assembly step (step S12). In step S11, as described above, (1) The outlet 5A of the injection pipe 5 is processed so as not to diffuse the water or hot water W (the diffusion mechanism is removed), (2) The pump discharge pipe 4 and the injection pipe 5 penetrate the lid 2 of the container 1; (3) Connect the hose 8 to the outlet 5A of the injection pipe 5. (4) A curved portion 8B is formed near the hose tip 8. (5) The inner diameter of the hose tip 8A is reduced.

[0026] Each of the processing steps constituting step S11 will now be described. In step S11, in order to "remove the diffusion mechanism of the outlet portion 5A of the injection pipe 5" in (1), for example, a member (diffusion mechanism) such as a screw of the outlet portion 5A of the injection pipe 5 may be removed, and a tool with a sharp tip (for example, a drill bit) may be used to pierce the outlet portion (5A) of the injection pipe 5. If the outlet portion (5A) of the injection pipe 5 does not have a diffusion mechanism, this process is not necessary. To "pass the pump discharge pipe 4A and the spray pipe 5 through the lid 2 of the container 1" in step S11(2), for example, a through hole having the same outer diameter as the pump discharge pipe 4A and a through hole having the same outer diameter as the spray pipe 5 are drilled in the lid 2 of the container 1, a sealant is placed in each of the two through holes to make them airtight and liquidtight, and the pump discharge pipe 4A and the spray pipe 5 are inserted into the corresponding through holes. Then, the pump discharge pipe 4A and the spray pipe 5 are fixed to the lid 2 of the container 1. Here, when a commercially available pump is used, the pump discharge pipe 4A and the spray pipe 5 may be processed integrally with the container 2, and in such a case, the process of passing the pump discharge pipe 4A and the spray pipe 5 through the lid of the container 2 is not necessary.

[0027] 5, when "connecting the hose 8 and the outlet 5A of the spray pipe 5" in step S11(3), the inner diameter of the hose 8 and the outer diameter of the outlet 5A of the spray pipe 5 often do not match. In such a case, the end of the hose 8 (to be connected to the outlet 5A of the spray pipe 5) may be enlarged in diameter with a tool (e.g., needle-nose pliers), and the enlarged end of the hose 8 may be placed over the outlet of the spray pipe 5 to connect them. To "machine the curved portion 8B near the hose tip 8" in step S11(4), for example, first, wind a fiber (e.g., "octopus thread") many times around the area of ​​the hose 8 where the curved portion 8B is to be formed, curve the area around which the octopus thread is wound to a predetermined radius of curvature, and then fix it in that state. When fixing, an adhesive (e.g., epoxy adhesive) is applied to the curved area and allowed to harden, so that the predetermined curved portion 8B can be formed at the desired position of the hose 8. In order to "reduce the hose inner diameter at the hose tip 8A" in step S11 (5), if the hose 8 is made of a thermally deformable material such as a silicon-based material or a resin-based material, the hose inner diameter can be reduced by heating and stretching the hose 8. Alternatively, instead of reducing the inner diameter of the hose tip, a nozzle with a predetermined nozzle diameter may be attached.

[0028] In step S12, the lid 2 of the container 1 is screwed onto the container 1, so that the components other than the container 1 (the pump unit 3 and the hose 8) can be assembled to the container. In the manufacturing method of the portable bottom washing device 10 according to the embodiment, each of the components can be manufactured by oneself to manufacture the washing device 10 shown in Fig. 1, but it is also possible to manufacture the pump unit 3 by modifying a commercially available product such as a household sprayer. When manufacturing the washing device 10 by such modification, the washing device 10 can be manufactured by a simple method as shown in steps S11 and S12 of Fig. 5.

[0029] It should be noted that the illustrated embodiment is merely an example and is not intended to limit the technical scope of the present invention.
