Summary of the Invention

Problems to be Solved by the Invention

[0004] The handwashing device as described in Patent Document 1 is a large device formed by processing a drum can and cannot be easily carried and used.

[0005] Note that such a problem is not limited to the device for handwashing, but is the same for all liquid discharging units that circulate liquid internally for filtration and liquid discharging.

[0006] Therefore, an object of the present invention is to provide a liquid discharging unit that can compactly accommodate a mechanism for liquid circulation.

Means for Solving the Problems

[0007] The discharge unit of the present invention comprises a housing having a bottom plate and an outer wall rising upward from the bottom plate, a pump, and a filter, wherein the housing comprises a discharge section for discharging liquid, a receiving section for receiving the liquid discharged by the discharge section, a reservoir for storing the liquid received by the receiving section, and a housing section for housing the pump, wherein the pump is configured to send the liquid stored in the reservoir to the discharge section, the filter is provided to filter the liquid from the time the liquid received by the receiving section is sent to the discharge section, the receiving section comprises a receiving bottom located spaced upward from the bottom plate, the reservoir is located between the receiving bottom and the bottom plate and is configured to allow the liquid received by the receiving section to flow in, and the housing section is located between the reservoir and the outer wall in a horizontal direction perpendicular to the vertical direction.

[0008] With this configuration, the housing section for the pump is located horizontally between the reservoir section and the outer wall section, allowing the pump to be compactly housed within the casing.

[0009] Furthermore, the housing can be configured to be a cylindrical shape extending vertically with an open top, and the reservoir portion can be positioned off-center from the horizontal center of the bottom plate portion.

[0010] With this configuration, since the reservoir is positioned off-center from the bottom plate, the distance from the reservoir to the outer wall can be increased. Therefore, the housing can be placed in the wider horizontal section, making it easier to place the pump in the housing.

[0011] Furthermore, the receiving base can be configured to be positioned below the vertical center of the housing.

[0012] With this configuration, the vertical length of the receiving section can be increased, which helps to prevent liquid splashing inside the receiving section from spilling out.

[0013] Further, the housing is a tubular shape extending in the vertical direction with an open upper portion, the receiving portion is a tubular shape with an open upper portion, having a receiving bottom portion and a receiving side wall portion extending in the vertical direction from the receiving bottom portion to the upper end portion of the housing, and the liquid discharging portion can be configured to discharge liquid radially inward from the receiving side wall portion.

[0014] According to such a configuration, since the liquid discharging portion discharges liquid radially inward from the receiving side wall portion, it is possible to suppress the liquid discharging portion from protruding above the housing, and the liquid discharging unit can be arranged compactly.

[0015] The filter can be arranged between the receiving bottom portion and the storage portion and configured to filter the liquid flowing from the receiving portion to the storage portion.

[0016] According to such a configuration, since the pump feeds the filtered liquid, it is possible to suppress the pump from being clogged by foreign matters or the like.

Advantages of the Invention

[0017] According to the present invention, it is possible to obtain a liquid discharging unit that can compactly accommodate a mechanism for liquid circulation.

[0019] The saliva unit 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. For the sake of explanation, the vertical direction, the horizontal direction, and the front-back direction will be described based on the directions shown in FIGS. 1 and 2.

[0020] As shown in FIGS. 1 to 3, the saliva unit 1 includes a housing 2, a pump 3, a power supply unit 4, a filter 5, and a saliva discharging unit 6. The saliva unit 1 of the present embodiment has a bottomed cylindrical shape with an open top, specifically, a cylindrical shape. Further, the saliva unit 1 is a filtration circulation type saliva unit 1 that circulates the liquid inside while filtering it. Furthermore, the saliva unit 1 is of a size that can be lifted and carried by a person. Specifically, the total weight of the whole is 20 kg or less, and the total length of the three sides (the sum of the vertical length, the horizontal length, and the front-back length) is 180 cm or less. The saliva unit 1 of the present embodiment is of a size that can be lifted and carried by a person with one hand, the total weight of the whole is 2 kg or less, and the total length of the three sides is 100 cm or less. Note that the weight of the saliva unit 1 is the weight in the state where no liquid is contained.

[0021] The housing 2 includes an outer surface portion 21 of a bottomed cylindrical shape, a receiving portion 22 disposed in the internal space of the outer surface portion 21, a storage portion 23 disposed below the receiving portion 22 in the internal space of the outer surface portion 21, a storage portion 24 disposed between the outer surface portion 21 and the storage portion 23, and a saliva storage portion 25 disposed between the outer surface portion 21 and the receiving portion 22.

[0022] The outer surface portion 21 includes a flat plate-shaped bottom plate portion 211 that extends in the horizontal direction, and an outer wall portion 212 that rises upward from the outer edge portion of the bottom plate portion 211. The bottom plate portion 211 is a plate-like body having a circular shape in plan view. Specifically, the bottom plate portion 211 includes a bottom plate body 213 in which a hole penetrating in the vertical direction is formed in a part of the horizontal direction, and a detachable plate portion 214 that is detachable from below the bottom plate body 213 and covers the hole formed in the bottom plate body 213 from below.

[0023] The outer wall portion 212 is cylindrical in shape, with its lower end connected to the outer edge of the base plate body 213 and extending upward. The outer wall portion 212 has a smooth outer surface extending in the vertical direction. Specifically, the outer wall portion 212 includes a bulging portion 215 whose outer diameter increases as it moves upward from the lower end, a reduced diameter portion 216 extending from the upper end of the bulging portion 215 to the upper end of the outer wall portion 212, with its outer diameter decreasing as it moves upward, and an upper end fitting portion 217 provided at the upper end of the reduced diameter portion 216 into which the discharge portion 6, described later, is fitted. The vertical length of the bulging portion 215 is shorter than the vertical length of the reduced diameter portion 216, specifically, it is less than half the vertical length of the reduced diameter portion 216. The bulging portion 215 and the reduced diameter portion 216 are smoothly connected, so that the outer surface of the outer diameter portion forms a smooth surface. Furthermore, the maximum outer diameter of the bulging portion 215 is 1.2 times or less the outer diameter of the base plate body 213, and the minimum outer diameter, which is the outer diameter at the upper end of the reduced diameter portion 216, is approximately the same as the outer diameter of the base plate body 213. In addition, the radial length (thickness) of the bulging portion 215 and the reduced diameter portion 216 is approximately constant.

[0024] The upper end fitting portion 217 is a projection that protrudes inward from the upper end of the reduced diameter portion 216 and is provided to extend continuously around the circumference. The upper end fitting portion 217 also has an upwardly concave groove formed on its lower end surface. This groove is formed to extend continuously around the circumference and is configured to allow the discharge portion 6 to be fitted from below.

[0025] The receiving portion 22 is a bottomed cylindrical body with an open top, positioned inside the outer surface portion 21. Specifically, the receiving portion 22 is a plate-like structure extending horizontally, comprising a receiving bottom portion 221 that forms the bottom of the receiving portion 22, and a receiving side wall portion 222 that extends upward from the outer edge of the receiving bottom portion 221 and forms the side wall of the receiving portion 22. The receiving portion 22 is a cylindrical body whose outer diameter is smaller than the inner diameter of the outer surface portion 21, and in this embodiment, it has a substantially constant outer diameter in the vertical direction. The receiving portion 22 is positioned substantially concentrically with the housing 2. Furthermore, the vertical length of the receiving portion 22 is shorter than the vertical length of the outer surface portion 21. In this embodiment, the vertical length of the receiving portion 22 is more than half the vertical length of the entire housing 2, and less than or equal to 3 / 4 of the vertical length.

[0026] The receiving base portion 221 is a plate-like body with an inclined shape such that its radially outer side is located upward and its central portion is located downward. The receiving base portion 221 also has a receiving hole 22a that penetrates vertically. The receiving hole 22a is formed at a position off-center from the horizontal central portion of the receiving base portion 221, and in this embodiment, it is formed at a position off-center to the front. Furthermore, the inner diameter of the receiving hole 22a is at least half the outer diameter of the receiving base portion 221, and less than half the outer diameter of the outer wall portion 212.

[0027] The support base 221 is positioned above and spaced apart from the bottom plate 211, and a space extending vertically is formed between the lower surface of the support base 221 and the upper surface of the bottom plate 211. The distance from the support base 221 to the bottom plate 211 is less than half the vertical length of the housing 2 and more than one-quarter of it.

[0028] The receiving side wall portion 222 is a cylindrical body extending upward from the outer edge of the receiving bottom portion 221, with its inner surface extending straight along the vertical direction. The receiving side wall portion 222 is positioned spaced apart from the inner circumferential surface of the outer wall portion 212, and a gap is formed between the outer circumferential surface of the receiving side wall portion 222 and the inner circumferential surface of the outer wall portion 212.

[0029] The reservoir 23 is located below the receiving bottom 221 and is positioned so that liquid can flow from the receiving portion 22. Specifically, the reservoir 23 is a cylindrical body that extends continuously downward from the receiving hole 22a and extends continuously from the receiving bottom 221 to the bottom plate 211. Specifically, the reservoir 23 comprises a reservoir cylinder 231 whose upper end is connected to the periphery of the receiving hole 22a and whose lower end is connected to the upper surface of the bottom plate 211, and a liquid discharge portion 232 for discharging liquid from the inside of the reservoir cylinder 231 to the outside. The reservoir 23 is positioned off-center from the central part of the receiving bottom 221 in the horizontal direction. In other words, in this embodiment, the axis of the outer surface 21 and the axis of the receiving portion 22 are configured to coincide, and the axis of the reservoir 23 is positioned offset outward from the axes of the outer surface 21 and the receiving portion 22.

[0030] The reservoir cylinder portion 231 is a cylindrical body that extends straight in the vertical direction and has a substantially constant inner diameter along the vertical direction. The inner diameter of the reservoir cylinder portion 231 is substantially the same as the inner diameter of the receiving hole 22a, specifically, the inner diameter is more than half the outer diameter of the receiving bottom portion 221 and less than half the outer diameter of the outer wall portion 212. Furthermore, the vertical length of the reservoir cylinder portion 231 is shorter than half the vertical length of the housing 2 and longer than 1 / 4.

[0031] As shown in Figures 3 and 4, the liquid discharge section 232 is a tubular body that connects the inside and outside of the reservoir section 231 and extends radially outward from the reservoir section 231. In this embodiment, the liquid discharge section 232 is a tubular body that extends radially outward from an opening formed at the lower end of the reservoir section 231 and is configured so that liquid can flow through its interior. The liquid discharge section 232 extends from the reservoir section 231 to the pump 3, and can discharge the liquid in the reservoir section 231 to the pump 3.

[0032] As shown in Figures 3 and 4, the housing section 24 is located between the outer wall section 212 and the reservoir section 23, and houses the pump 3 and the power supply section 4. Specifically, the housing section 24 is formed by the inner surface of the outer wall section 212, the upper surface of the bottom plate section 211, the outer surface of the reservoir section 23, and the lower surface of the receiving bottom section 221, forming a housing space S that extends in the vertical and radial directions.

[0033] As shown in Figure 4, the storage space S includes a wide space S1 located on the opposite side of the side where the storage section 23 is located off-center in the horizontal direction perpendicular to the vertical direction, and a narrow space S2 located on the side where the storage section 23 is located off-center. The wide space S1 is wider in the front-to-back direction than the narrow space S2. In this embodiment, the wide space S1 is the area behind the center of the housing 2 in the horizontal direction, and the narrow space S2 is the area in front of the center of the housing 2 in the horizontal direction. The wide space S1 also includes a first wide space S11, which is the area to the left of the center of the housing 2 in the horizontal direction, and a second wide space S12, which is the area to the right of the center of the housing 2 in the horizontal direction. The narrow space S2 includes a first narrow space S21, which is the area to the left of the center of the housing 2 in the horizontal direction, and a second narrow space S22, which is the area to the right of the center of the housing 2 in the horizontal direction.

[0034] Furthermore, as shown in Figure 3, the housing section 24 is provided in the range where the bulging section 215 is located in the vertical direction. In other words, the radially outer surface of the housing section 24 is formed by the inner surface of the bulging section 215. Therefore, the housing space S is formed so that it is wider at the top than at the bottom.

[0035] The discharge portion 25 is located between the receiving portion 22 and the outer wall portion 212 and accommodates the discharge portion 6. Specifically, the discharge portion 25 is formed by the inner surface of the outer wall portion 212 and the outer surface of the receiving side wall portion 222, forming a space that extends in the vertical and radial directions. Furthermore, the discharge portion 25 is arranged continuously with the storage portion 24 in the vertical direction, and the storage space S and the internal space of the discharge portion 25 are in communication in the vertical direction.

[0036] As shown in Figure 4, the pump 3 pumps the liquid from the reservoir 23 to the discharge section 6. Specifically, the pump 3 comprises a liquid pumping drive unit 31 that generates driving force for pumping liquid, and a liquid pumping body unit 32 that operates and pumps liquid using the driving force of the liquid pumping drive unit 31. In this embodiment, the liquid pumping drive unit 31 is a motor that receives electricity and generates rotational force as driving force, and the liquid pumping body unit 32 has an impeller (not shown) that rotates with the rotational force, and is configured to pump liquid by the rotation of the impeller. In this embodiment, the outer diameter of the liquid pumping body unit 32 is larger than the outer diameter of the liquid pumping drive unit 31, and the liquid pumping body unit 32 is connected to the liquid pumping drive unit 31 so as to be aligned in the direction in which the motor shaft extends and become one unit. With the liquid pumping body unit 32 and the liquid pumping drive unit 31 connected, the longitudinal direction of the pump 3 in the horizontal direction coincides with the direction in which the motor shaft extends, and the short direction coincides with the direction perpendicular to the motor shaft in the horizontal direction. Furthermore, the liquid delivery main body 32 is configured such that the reservoir 23 and the discharge section 6 can be connected to the end opposite to the side to which the liquid delivery drive unit 31 is connected.

[0037] The power supply unit 4 is configured to supply power to the pump 3. Specifically, the power supply unit 4 includes a battery installation unit 41 where a battery for supplying power to the pump 3 is installed, and a main power supply unit 42 and a sensor unit 43 that open and close the circuit between the pump 3 and the power supply unit 4.

[0038] The battery mounting section 41 is a box-shaped body having a longitudinal direction and a transverse direction, and in this embodiment, it is a rectangular parallelepiped. The battery mounting section 41 has terminals that come into contact with the battery to be installed, located at one end and the other end in the longitudinal direction. In addition, a primary battery can be installed in the battery mounting section 41 of this embodiment. The battery installed in the battery mounting section 41 is replaced by removing the attachment plate section 214.

[0039] The main power supply unit 42 is a switch for opening and closing the circuit between the pump 3 and the power supply unit 4. In this embodiment, the main power supply unit 42 has an operating part for opening and closing the circuit exposed below the bottom plate 211, and is configured so that the circuit can be opened and closed from outside the housing 2.

[0040] As shown in Figure 1, the sensor unit 43 is a motion sensor provided at the upper end of the receiving unit 22. It is configured to detect moving objects at the upper end of the receiving unit 22, such as a person's fingers entering the receiving unit 22, and to close the circuit between the pump 3 and the power supply unit 4 for a predetermined time after detection. In other words, the power supply unit 4 in this embodiment is configured to supply power from the battery installation unit 41 to the pump 3 when the main power supply unit 42 is in a closed circuit state and the sensor unit 43 is in a closed circuit state.

[0041] As shown in Figure 4, the discharge unit 6 comprises a tubular fluid guide section 61 connected to the pump 3, and a discharge unit 62 connected to the fluid guide section 61 that discharges the supplied fluid. The fluid guide section 61 is a flexible tubular body that can be bent in the axial direction.

[0042] The discharge body 62 is an annular body provided along the upper end of the receiving portion 22, and has multiple discharge holes 6b formed on its inside for discharging water. Specifically, the discharge body 62 has a discharge space 6a that can store the liquid sent from the fluid guide portion 61, and discharge holes 6b are formed that penetrate radially through the discharge surface 6c, which is the radially inward end face, and communicate the inside and outside of the discharge space 6a. The discharge space 6a is formed to extend continuously in the circumferential direction. The discharge surface 6c also extends continuously in the vertical direction with respect to the inner surface of the receiving side wall portion 222.

[0043] The discharge holes 6b are holes that extend radially along the housing 2 and are formed in multiple locations spaced apart in the circumferential direction. There are eight or more discharge holes 6b formed at equal intervals in the circumferential direction, and in this embodiment there are 18 (see Figure 2). Furthermore, the discharge holes 6b are smaller than the inner diameter of the fluid guide section 61 and are of a size that allows liquid to be ejected inward from the discharge body section 62 by the pressure supplied by the pump 3.

[0044] The discharge body 62 is connected to the housing 2 by fitting its upper end into the upper end fitting portion 217. Furthermore, the entire discharge body 62 and the fluid guide portion 61 are housed in the discharge reservoir portion 25. In other words, the entire discharge portion 6 is located below the upper end of the housing 2.

[0045] In this embodiment, the discharge section 6, receiving section 22, reservoir section 23, and bottom plate body 213 are integrally formed, and the parts forming the discharge section 6, receiving section 22, reservoir section 23, and bottom plate body 213 are joined to the parts constituting the outer wall section 212 to form the housing 2 and the discharge section 6.

[0046] As shown in Figure 5, the filter 5 comprises a pre-filter section 51 located upstream in the direction of liquid flow, a main filter section 52 located downstream of the pre-filter section 51, and a cover section 53 that covers the pre-filter section 51. In this embodiment, the filter 5 has the cover section 53, the pre-filter section 51, and the main filter section 52 arranged in a vertical direction. The filter 5 is a plate-like body that extends horizontally and is sized to fit into the receiving hole 22a, and is positioned by being fitted into the receiving hole 22a, for example, via an O-ring. In other words, the filter 5 filters the liquid that flows through the receiving hole 22a to the reservoir section 23 before it flows into the reservoir section 23.

[0047] The pre-filter section 51 is a plate-like body with multiple holes formed through it in the thickness direction, and in this embodiment, it is a mesh plate with multiple circular holes. The pre-filter section 51 removes dust particles larger than the diameter of the circular holes formed from the flowing liquid.

[0048] The main filter section 52 comprises a filtration member 54 that further filters the liquid filtered by the pre-filter section 51, and a filter support section 55 that supports the filtration member 54. The filter support section 55 is a bottomed cylindrical shape with an open top, comprising a plate-shaped support bottom plate 56 and a support side wall 57 that rises upward from the outer edge of the support bottom plate 56. In this embodiment, the filter support section 55 is circular in plan view. Furthermore, the main filter section 52 is configured such that the outer edge of the pre-filter section 51 and the upper end of the support side wall 57 are liquid-tightly connected below the pre-filter section 51, so that only the liquid that has passed through the pre-filter section 51 reaches the main filter section 52. In this embodiment, the liquid that has passed through the pre-filter section 51 temporarily accumulates in the filter support section 55.

[0049] The filtration member 54 is cylindrical in shape, allowing liquid to penetrate from its outer surface to the interior, and is configured to remove solid matter as the liquid penetrates. The filtration member 54 in this embodiment is a cylindrical ceramic filter. The filtration member 54 is a cylindrical body with one end and the other end open in the axial direction. These filtration members 54 are arranged horizontally on the upper surface of the support base, and are configured so that the axial lengths of adjacent filtration members 54 differ so that they fit within the filter support portion 55 in a plan view. Specifically, the axial length of the filtration members 54 is such that one end and the other end of the horizontally aligned filtration members 54 are aligned along the outer edge of the filter support portion 55. Because the filtration members 54 are arranged in this way, the entire filter portion 52 is formed in a plate shape in a plan view. Furthermore, the filtration member 54 is positioned so that one end and the other end in the axial direction penetrate the support side wall 57, thereby being supported by the support side wall 57, and both ends in the axial direction are exposed to the radially outward side of the support side wall 57.

[0050] The filtration member 54 is configured to filter the liquid accumulated in the filter support portion 55 and discharge the filtered liquid from one end and the other end in the axial direction. In this embodiment, the liquid accumulated in the filter support portion 55 is filtered as it permeates from the outer circumferential surface of the filtration member 54 into the interior, and the filtered liquid is discharged to the outside of the filter portion 52 from one end and the other end in the axial direction.

[0051] The cover portion 53 is positioned above the pre-filter portion 51 at a distance from it and is a plate-like body that covers the pre-filter portion 51 from above. The cover portion 53 is connected to the pre-filter portion 51, for example, by a shaft that extends upward from the upper surface of the pre-filter portion 51.

[0052] Next, the arrangement of the pump 3 and the power supply unit 4 in the housing section 24 will be explained with reference to Figure 4.

[0053] As shown in Figure 4, the pump 3 is positioned in the wide space S1 for the majority of its size (more than 90% of the combined volume of the liquid delivery drive unit 31 and the liquid delivery body 32). The pump 3 is also positioned to extend from the first wide space S11 to the second wide space S12. Furthermore, the pump 3 is positioned such that the liquid delivery drive unit 31 is located on the second wide space S12 side and the liquid delivery body 32 is located on the first wide space S11 side. The liquid delivery body 32 is positioned across the first wide space S11 and the first narrow space S21, and the liquid delivery body 32 and the reservoir 23 are connected within the first narrow space S21. The liquid delivery drive unit 31 is also positioned across the first wide space S11 and the second wide space S12. Specifically, the motor shaft of the liquid delivery drive unit 31 of the pump 3 is positioned to extend in a direction that intersects the front-to-back and left-to-right directions of the housing 2. In this embodiment, the motor shaft of the liquid transfer drive unit 31 of the pump 3 is positioned such that it extends from the left end side of the housing unit 24 (opposite the side where the reservoir unit 23 is located off-center) toward the rear end side.

[0054] The power supply unit 4, excluding the sensor unit 43, is located spanning from the second wide space S12 to the second narrow space S22. Specifically, the power supply unit 4 has a battery mounting section 41 that spans from the second wide space S12 to the second narrow space S22, and a main power supply unit 42 located in the second wide space S12 between the battery mounting section 41 and the fluid supply drive unit 31. The main power supply unit 42 is positioned so that its longitudinal direction coincides with the left-right direction, with one end of the longitudinal direction located in the second narrow space S22 and the other end located in the second wide space S12. The power supply unit 4 is electrically connected to the fluid supply drive unit 31 via wiring provided in the second wide space S12 and the second narrow space S22.

[0055] The method of using the discharge unit 1 with the above configuration will be explained with reference to Figure 6.

[0056] As shown in Figure 6, when using the dispensing unit 1, first, the dispensing unit 1 is carried to the place of use, positioned, and liquid is collected in the reservoir 23. In this embodiment, the liquid is, for example, tap water for handwashing, and tap water is collected in the reservoir 23. Next, the main power supply unit 42 is operated to supply power from the power supply unit 4 to the pump 3. In this state, by placing an object (for example, fingers) into the receiving unit 22, the sensor unit 43 detects the movement and closes the circuit connecting the power supply unit 4 and the pump 3, thereby supplying power to the pump 3 and driving the pump 3.

[0057] When pump 3 is activated, it draws liquid from the reservoir 23 and sends the drawn liquid to the discharge section 6. The liquid sent to the discharge section 6 passes through the fluid guide section 61 and reaches the discharge body section 62, where the liquid accumulates in the discharge space 6a. When more liquid is pumped from pump 3 in this state, the liquid pressure from the pumping causes the liquid in the discharge space 6a to be ejected radially inward from the discharge holes 6b. Here, since the liquid pressure is applied almost uniformly to the liquid in the discharge space 6a, the force of the liquid ejected from each discharge hole 6b is also almost uniform. The liquid ejected from each discharge hole 6b intersects at the liquid intersection position P in the radial center of the receiving section 22. The liquid intersection position P is located above the central part in the vertical direction of the receiving section 22, and in this embodiment, it is located within the upper 1 / 3 range. This ejected liquid can be used, for example, to wash hands or objects.

[0058] The liquid ejected from the discharge port 6b moves downward due to gravity and flows to the filter 5. There, it is filtered, and the filtered liquid is collected again in the collection section 23. In this way, the discharge unit 1 can reuse the discharged liquid by filtering and collecting it, so it can continuously discharge even small amounts of liquid.

[0059] With the discharge unit 1 configured as described above, the housing section 24 that houses the pump 3 is located horizontally between the reservoir section 23 and the outer wall section 212, so the pump 3 can be compactly housed inside the housing 2.

[0060] Furthermore, since the pump 3 is configured to extend in directions that intersect the front-to-back and left-to-right directions within the housing section 24, the pump 3 can be positioned efficiently in terms of space.

[0061] Furthermore, the liquid supply main body 32 is arranged across the first wide space S11 and the first narrow space S21, and is configured to be connected to the reservoir 23 and the discharge section 6 in the first wide space S11 and the first narrow space S21, the liquid supply drive unit 31 is arranged across the first wide space S11 and the second wide space S12, the power supply unit 4 is arranged across the second wide space S12 and the second narrow space S22, and the power supply unit 4 and the liquid supply drive unit 31 are connected in the second wide space S12. Thus, the connection of the liquid to the pump 3 can be completed in the first wide space S11 and the first narrow space S21, and the connection of the power to the pump 3 can be completed in the second wide space S12, so that the arrangement and connection of components within the housing 24 can be carried out space efficiently.

[0062] Furthermore, since multiple discharge holes 6b are formed spaced apart in the circumferential direction, liquid can be discharged from multiple points in the circumferential direction. Therefore, even if the amount of liquid to be discharged is small, it is easy to use. In particular, when washing hands or objects, liquid is supplied from multiple points on the outside of the object being washed, making washing easier.

[0063] Furthermore, since the liquid discharged from each discharge port 6b intersects at the liquid intersection point P, the liquid is supplied evenly from multiple points in the circumferential direction at the liquid intersection point P. Therefore, even if the amount of liquid to be discharged is small, it is easy to utilize the liquid.

[0064] Furthermore, since the filter 5 is positioned to fit into the receiving hole 22a, the liquid is filtered before it flows into the reservoir 23. This prevents the reservoir 23 from becoming contaminated.

[0065] Although embodiments of the present invention have been described above with reference to one example, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0066] For example, although the discharge unit 1 was described using the example of its use for washing hands or objects, it is not limited to this configuration and can be used for a variety of purposes.

[0067] Furthermore, although the example described shows the discharge section 6 located below the upper end of the housing 2, the configuration is not limited to this, and it can also be configured to be located above the upper end of the housing 2.

[0068] Furthermore, although the explanation has used a top-opening housing 2 and receiving portion 22 as an example, the configuration is not limited to this, and for example, the housing 2 and receiving portion 22 can also be configured as a cylindrical shape with openings on the sides.

[0069] Furthermore, although the example described uses a case where the reservoir 23 is positioned off-center from the horizontal center, the configuration is not limited to this, and the reservoir 23 can also be positioned in the central part.

[0070] Furthermore, although the receiving portion 22 was described as being cylindrical with a receiving bottom portion 221 and a receiving side wall portion 222, it is not limited to this configuration and can be configured in other shapes such as a mortar shape.

[0071] Furthermore, although the filter 5 was described using the example of having multiple cylindrical filter members 54, it is not limited to this configuration, and for example, it can also be configured to have a single plate-shaped filter member 54. Also, although the filter 5 was described using the example of having a pre-filter section 51 and a main filter section 52, it is not limited to this configuration, and it can also be configured without a pre-filter section 51. Furthermore, even when a pre-filter section 51 is provided, it can be configured to have a pre-filter section 51 with the same performance as the main filter section 52. In addition, although the filter member 54 was described using the example of a ceramic filter, for example, a filter 5 using activated carbon (specifically, a laminated activated carbon filter) can also be used. Moreover, even when multiple cylindrical filter members 54 are provided, they are not limited to being arranged so that the axial direction of the filter members 54 is horizontal, but can also be configured so that the axial direction of the filter members 54 is vertical. In such a configuration, for example, the upper axial end portion of the filter member 54 may be left open while the lower end portion is closed, so that the liquid before filtration flows into the interior from the upper end of the filter member 54. The filtered liquid is filtered as it permeates from the interior to the outer surface of the filter member 54, and the filtered liquid moves from the outer surface of the filter member 54 to the reservoir 23.

[0072] Furthermore, although the explanation described an example where the power supply unit 4 is equipped with a battery installation unit 41 and is driven by power supplied from the battery, the configuration is not limited to this, and it is also possible to configure it to be driven by power supplied from an external power source. In such a configuration, a conversion device that converts the external power source so that it can drive the motor can be placed in place of the battery installation unit 41.
