Abstract

PROBLEM TO BE SOLVED: To provide a urinal device capable of suppressing emission of an odor.SOLUTION: A urinal device includes: washing water supply means for supplying water to a bowl part of a urinal; a trap part that is provided in a lower part of the bowl part and into which urine and the water flow; and washing water spray means for spraying the water, which is changed into droplets, to an area within the bowl part and either of areas between the trap part and a position of a user's nose facing the bowl part. Timing when the washing water spray means sprays the water changed into droplets is different from timing when the washing water supply means supplies the water.

Description

  Aspects of the present invention generally relate to a urinal device.

  Regarding the odor generated from the urinal device, the odor of the urinal device may not be sufficiently removed by simply washing the bowl portion of the urinal device with water. Therefore, various deodorizing devices for removing the odor of the urinal device have been proposed. It is considered that the main source of the odor of the urinal device is ammonia produced by the decomposition of urine remaining in the urinal device by general bacteria. Specifically, urine remaining in the trap of the urinal device is decomposed by an enzyme to produce ionized ammonia and gasified ammonia.

  When energy from urination (for example, heat or water flow) is added to ammonia ions, the ammonia ions become ammonia gas. When a temperature difference occurs due to urination, the ammonia gas rides on the rising airflow and reaches the position of the user's nose. Thus, the ammonia gas generated within a few seconds after urination reaches the position of the user's nose, so that the user feels an unpleasant odor.

  As one of the measures for removing the odor of the urinal device, a toilet unit with a sterilizing water supply function that suppresses generation of odor caused by ammonia or the like by sterilizing general bacteria has been proposed (Patent Document 1). However, it is difficult to completely sterilize general bacteria. In this regard, there is room for improvement in the toilet unit with the sterilizing water supply function described in Patent Document 1.

  In addition, when the flush valve is operated with the cartridge installed in the hole, the cleaning agent flowing into the empty space partially elutes the cleaning agent in the cartridge and flows out of the sprinkling hole into the urine receiving recess. There is a flushing device for urinals (Patent Document 2). However, the water urinal washing apparatus described in Patent Document 2 supplies a cleaning agent into the male urinal together with the washing water when the male urinal is washed. For this reason, it is not possible to suppress the urine remaining in the male urinal after use of the male urinal from being decomposed by general bacteria and producing ammonia.

  The present invention has been made on the basis of recognition of such a problem, and an object thereof is to provide a urinal device capable of suppressing the generation of odor.

  A first invention is a washing water supply means for supplying water to a bowl portion of a urinal, a trap portion provided at a lower portion of the bowl portion, into which urine and water flow, and an area inside the bowl portion, Cleaning water sprinkling means for sprinkling water droplets in any region between the position of the user's nose facing the bowl portion and the trap portion, wherein the cleaning water sprinkling means is the liquid The urinal apparatus is characterized in that the timing of spraying the dropletized water is different from the timing at which the washing water supply means supplies water.

  According to this urinal device, the washing water supply means cleans the bowl portion of the urinal. The washing water sprinkling means sprinkles droplets of water and dissolves ammonia generated from the trap portion. Thereby, it can suppress that a user senses the smell by the ammonia which generate | occur | produces from a trap part. Moreover, according to this urinal device, the odor due to ammonia generated from the urinal can be efficiently suppressed.

  In a second aspect based on the first aspect, the cleaning water sprinkling means has a water sprinkling portion provided at an upper portion of the bowl portion, and the water sprinkling portion is formed into droplets below the bowl portion. A urinal device characterized by sprinkling water.

  According to this urinal device, since the water sprinkling part sprays the water droplets downward from the bowl part, an air flow downward from the water sprinkling part is generated inside the bowl part. Therefore, the airflow generated inside the bowl portion can suppress the increase in ammonia. Moreover, the water sprayed from the water spray part dissolves ammonia. Thereby, it can suppress that a user senses the smell by the ammonia generated from a urinal.

  In addition to sprinkling water droplets, the smell of ammonia near the ammonia generation source on the surface of the bowl can be suppressed, and when the droplets pass through the space, The odor caused by the existing ammonia can also be suppressed. Furthermore, the surface area of the water per unit water amount can be made significantly wider in the dropletized water than in the state of water traveling on the surface of the bowl portion. As a result, the area where water contacts with ammonia can be increased, and the odor can be efficiently suppressed. The odor present in the space includes not only ammonia caused by urine but also odor of the urine itself after the user urinates (for example, an odor derived from ingested food such as coffee odor). Regarding the odor, the odor can be suppressed by sprinkling water droplets.

  In a third aspect based on the first aspect, the cleaning water sprinkling means has a water sprinkling portion provided at a lower portion of the bowl portion, and the water sprinkling portion is formed into droplets above the bowl portion. A urinal device characterized by sprinkling water.

  According to this urinal device, since the water sprinkler sprinkles the water droplets above the bowl portion, at least a part of the water sprinkled from the water sprinkler can float outside the bowl portion. . The water drifting outside the bowl portion can dissolve the ammonia gas existing outside the bowl portion. This makes it difficult for the user to feel not only the smell of the urinal but also the smell around the urinal.

  4th invention is further equipped with the human body detection means which detects the user who exists ahead of the said urinal in any one invention of 1-3, When the said human body detection means detects the said user, The washing water sprinkling means is a urinal device that sprinkles the water droplets.

  According to this urinal device, before the user approaches the urinal and feels the odor due to ammonia gas, the washing water sprinkling means can spray water into the bowl portion and suppress the odor due to ammonia gas.

  According to the aspect of the present invention, a urinal device capable of suppressing the generation of odor is provided.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a block diagram showing a main part configuration of a urinal apparatus according to an embodiment of the present invention. In addition, FIG. 1 represents together the principal part structure of a waterway system and an electrical system.

  The urinal device 100 according to the present embodiment includes a first washing water supply unit 140, a second washing water supply unit (ammonia dissolving unit, washing water sprinkling unit) 160, and a urinal 170. The urinal device 100 according to the present embodiment may include a control unit 110, a human body detection unit 120, a flow path switching valve 130, and a functional water generation unit 150.

  The urinal 170 is a urinal for boys. The urinal 170 has a bowl portion 171 (see FIGS. 2 and 3) and a trap portion 173 (see FIG. 5). The trap part 173 is provided in the lower part of the bowl part 171, and forms sealed water inside the trap part 173 itself. Thereby, the trap part 173 can prevent a bad odor, pests, etc. invading a toilet room etc. from the horizontal drawing drain piping etc. which are provided in the back of the urinal apparatus 100, etc. Urine and water flow into the trap portion 173.

  Based on the signal transmitted from the control unit 110, the flow path switching valve 130 is in a state where water supplied from a water supply source (not shown) (for example, a water supply or a tank) is guided to the first washing water supply means 140, The state in which the water supplied from the water supply source is led to the second washing water supply means 160 is switched.

  The first washing water supply means 140 has a spreader 141 and supplies the water supplied from the water supply source to the bowl portion 171 of the urinal 170 via the flow path switching valve 130.

  The second washing water supply means 160 has a watering part 161, and water supplied from the water supply source via the flow path switching valve 130 and formed into droplets is supplied from the watering part 161 to the urinal 170. Supply to bowl 171. The water supplied from the sprinkler 161 to the bowl 171 of the urinal 170 can dissolve ammonia. The diameter of the water droplets sprayed by the second washing water supply means 160 is, for example, about 10 micrometers (μm) or more and 12000 μm or less. Details of the diameter of the water droplets sprayed by the second cleaning water supply means 160 will be described later.

Here, the mechanism of ammonia generation is, for example, as follows.
That is, when urination is performed in the toilet bowl, the urine adheres to the surface of the toilet bowl or stays in the sealed water (retained water) of the trap portion. General bacteria present in the air, on the toilet surface, etc., adhere to the retained urine. General bacteria absorb nutrients from urine, activate the activity of producing urease enzyme, and promote urea decomposition inhibition by urease enzyme. Urea is broken down into ammonia and carbon dioxide, which contributes to malodor. In addition, if the hydrogen ion concentration (pH) of the decomposed product is biased to alkaline due to the generated ammonia, and the pH is biased to alkaline exceeding 8.0 to 8.5, calcium ions dissolved in urine are difficult to be dissolved. It becomes a soluble calcium compound (such as calcium phosphate, also commonly called urolith). This urine stone becomes a hotbed of bacteria and accelerates the process so far to generate more ammonia.

  The functional water generating means 150 can generate functional water from the water supplied from the water supply source via the flow path switching valve 130 based on the signal transmitted from the control unit 110. Functional water can dissolve and decompose ammonia.

For example, the functional water generating means 150 has an anode plate (not shown) and a cathode plate (not shown) inside, and can electrolyze tap water and miscellaneous water flowing inside based on a signal transmitted from the control unit 110. Here, tap water contains chloride ions. Chloride ions are contained as salt (NaCl), calcium chloride (CaCl ₂ ) and the like in a water source (for example, groundwater, dam water, river water, etc.). Therefore, hypochlorous acid is produced by electrolyzing chloride ions. As a result, the water electrolyzed in the functional water generator 150 (electrolyzed water) changes to a liquid containing hypochlorous acid (functional water).
Hypochlorous acid functions as a deodorizing component or a bactericidal component. The liquid containing hypochlorous acid can dissolve or decompose ammonia or sterilize general bacteria.

  In addition, the functional water production | generation means 150 of this embodiment is not necessarily limited to producing | generating the liquid containing hypochlorous acid. The functional water generated in the functional water generating means 150 may be a liquid containing metal ions such as silver ions and copper ions. Or the functional water produced | generated in the functional water production | generation means 150 may be a liquid containing electrolytic chlorine, ozone, etc. Alternatively, the functional water generated in the functional water generating unit 150 may be acidic water or alkaline water. Among these, the solution containing hypochlorous acid can dissolve and decompose ammonia more. Further, the functional water generating means 150 is not limited to an electrolytic cell unit having an anode plate and a cathode plate.

When the functional water generating unit 150 generates functional water based on a signal transmitted from the control unit 110, the second washing water supply unit 160 uses the functional water generated by the functional water generating unit 150 to sprinkle the water. 161 is supplied to the bowl portion 171 of the urinal 170.
On the other hand, when the functional water generating means 150 does not generate functional water, the second washing water supply means 160 uses the water supplied from the water supply source via the flow path switching valve 130 and the functional water generating means 150 ( This water is referred to as fresh water, which is tap water or miscellaneous water supplied from a water supply source) from the sprinkler 161 to the bowl 171 of the urinal 170.

  The human body detection means 120 can detect a user who is in front of the urinal 170, that is, a user who is present at a position spaced forward from the urinal 170. As such a human body detection means 120, for example, an infrared light projecting / receiving distance measuring sensor, a pyroelectric sensor, a microwave sensor such as a Doppler sensor, or the like can be used.

  According to the present embodiment, the second washing water supply means 160 supplies water to the bowl portion 171 of the urinal 170, and ammonia generated inside the bowl portion 171 and ammonia present around the bowl portion 171. Is dissolved and decomposed. Ammonia existing around the bowl portion 171 refers to, for example, ammonia floating around the bowl portion 171 or ammonia floating around the bowl portion 171. Thereby, the 2nd washing-water supply means 160 can suppress the smell by the ammonia which generate | occur | produces from the urinal apparatus 100. FIG. Moreover, the 1st washing water supply means 140 can supply water to the bowl part 171 of the urinal 170, and can remove the urine adhering to the urinal 170, for example, can remove foreign substances, such as a body hair. In addition, the first washing water supply means 140 can supply water to the trap unit 173 of the urinal 170 and replace the sealed water inside the trap unit 173 with newly supplied water.

  The water sprayed from the second washing water supply means 160 and made into droplets efficiently uses at least one of ammonia generated inside the bowl portion 171 and ammonia existing around the bowl portion 171. Dissolves. As a result, when the second washing water supply means 160 sprinkles droplets of water from the sprinkler 161 to the bowl 171 of the urinal 170, the odor due to ammonia generated from the urinal device 100 is further suppressed. can do.

  The functional water sprayed from the second washing water supply means 160 dissolves and decomposes at least one of ammonia generated in the bowl portion 171 and ammonia present in the vicinity of the bowl portion 171. Thereby, when the second washing water supply means 160 sprinkles the functional water, for example, even if water in which ammonia is dissolved adheres around the urinal 170 and evaporates, the odor due to ammonia is generated again. Can be suppressed.

  As described above, the diameter of the water droplets sprayed by the second cleaning water supply means 160 is about 10 μm or more. Thereby, the extent to which the droplets sprayed from the second cleaning water supply means 160 continue to float in the space is reduced, and it is possible to suppress scattering to an unintended space. Therefore, it is possible to prevent the user from getting wet or the surroundings of the urinal 170 from being wetted by the droplets sprayed from the second washing water supply means 160. Moreover, the diameter of the water droplets sprinkled by the second washing water supply means 160 is about 1200 μm or less. Thereby, it can suppress that the droplet sprinkled from the 2nd washing water supply means 160 falls comparatively early, and the effect which melt | dissolves ammonia falls.

  Here, the definition of the numerical value of the diameter of water is described. The diameter of the water sprayed from the second washing water supply means 160 generally has a certain range. The particle diameter at the point where the distribution curve of the cumulative percentage of particle diameter intersects the horizontal axis of 50% is the 50% diameter (generally called the median diameter) as the water diameter.

FIG. 2 is a schematic perspective view illustrating the installation form of the second cleaning water supply means of the present embodiment.
As shown in FIG. 2, for example, the watering part 161 of the second washing water supply means 160 is provided on the upper part of the bowl part 171 of the urinal 170. The water sprinkling unit 161 sprinkles the water droplets downward from the bowl unit 171. Here, “downward” is not limited to the downward direction in the vertical direction, but includes the direction from the horizontal direction to the lower side. In other words, “downward” here refers to the direction excluding the horizontal direction and the direction above the horizontal direction.

  According to this, since the water sprinkling part 161 sprinkles water formed into droplets from the upper part of the bowl part 171, an air flow directed downward from the water sprinkling part 161 is generated inside the bowl part 171. Therefore, the airflow generated inside the bowl portion 171 can suppress the increase in ammonia. Moreover, the water sprayed from the water sprinkling part 161 melt | dissolves ammonia. Furthermore, when the water sprayed is functional water containing hypochlorous acid, in addition to dissolving ammonia, ammonia is decomposed into odorless substances. Thereby, a user becomes difficult to feel the smell by ammonia generated from the urinal device 100.

  In addition to sprinkling water droplets, the smell of ammonia near the ammonia generation source on the surface of the bowl portion 171 can be suppressed, and when the droplets pass through the space, It is also possible to suppress the odor caused by ammonia present in Furthermore, the surface area of the water per unit water amount can be made significantly wider in the droplet water than in the state of the water that travels on the surface of the bowl portion 171 supplied from the first washing water supply means 140. . As a result, the area where water contacts with ammonia can be increased, and the odor can be efficiently suppressed. The odor present in the space includes not only ammonia caused by urine but also odor of the urine itself after the user urinates (for example, an odor derived from ingested food such as coffee odor). Regarding the odor, it is possible to suppress the odor by sprinkling water droplets.

FIG. 3 is a schematic perspective view illustrating another installation form of the second cleaning water supply unit of the present embodiment.
As shown in FIG. 3, for example, the watering part 161 of the second washing water supply means 160 is provided in the lower part of the bowl part 171 of the urinal 170. The water sprinkling unit 161 sprinkles water that has been made droplets above the bowl unit 171. Here, “upward” is not limited to the upward direction in the vertical direction, but includes the upward direction from the horizontal direction. That is, the term “upward” here refers to a direction excluding the horizontal direction and the direction below the horizontal direction.

  According to this, since the water sprinkling part 161 sprinkles the water droplet-formed upward from the lower part of the bowl part 171, at least a part of the water sprinkled from the water sprinkling part 161 is outside the bowl part 171. Can drift. The water drifting outside the bowl portion 171 can dissolve the ammonia gas existing outside the bowl portion 171. This makes it difficult for the user to feel not only the odor of the urinal 170 but also the odor around the urinal 170.

FIG. 4 is a schematic perspective view showing an area of water supplied to the bowl portion of the present embodiment.
FIG. 4A is a schematic perspective view showing an area of water supplied from the first cleaning water supply means 140 of the present embodiment to the bowl portion 171. FIG. 4B is a schematic perspective view showing an area of water supplied from the second cleaning water supply means 160 of the present embodiment to the bowl portion 171.

  As shown in FIG. 4A, for example, the spreader 141 of the first washing water supply unit 140 is provided on the upper portion of the bowl portion 171 of the urinal 170. The installation form of the spreader 141 is not limited to the example shown in FIG. As in the first region 171 a illustrated in FIG. 4A, the spreader 141 supplies water to the substantially central portion of the bowl portion 171. That is, the first region 171a is a region inside the bowl portion 171 that is cleaned by the water supplied from the spreader 141 of the first cleaning water supply unit 140.

  Inside the bowl part 171, the 2nd area | region 171b exists in the right-and-left both sides (lateral side) of the 1st area | region 171a. The second region 171 b is a region inside the bowl portion 171 that is not cleaned by the water supplied from the spreader 141 of the first cleaning water supply unit 140. A third region 171 c exists in the lip portion 175 inside the bowl portion 171. Similar to the second region 171b, the third region 171c is a region inside the bowl portion 171 that is not cleaned by the water supplied from the spreader 141 of the first cleaning water supply means 140. In the present specification, the “lip portion” refers to a portion protruding forward from the side surface 179 of the urinal 170.

  As illustrated with reference to FIG. 2, for example, the sprinkling portion 161 of the second washing water supply means 160 is provided on the upper portion of the bowl portion 171 of the urinal 170. As in the fourth region 171 d shown in FIG. 4B, the water sprinkling unit 161 supplies water to substantially the entire bowl unit 171. That is, the fourth area 171 d is an area inside the bowl portion 171 and is a water spray area for water supplied from the water spray section 161 of the second cleaning water supply means 160. As shown in FIG. 4B, the fourth region 171d includes at least a part of the second region 171b. The fourth region 171d includes at least a part of the third region 171c.

  According to this, the second washing water supply means 160 is provided in at least a part of the areas (the second area 171b and the third area 171c) where water is not supplied by the first washing water supply means 140. Water can be sprinkled and supplied. Therefore, the first washing water supply means 140 can suppress the odor caused by ammonia generated from urine adhering to the area where water is not supplied. Thereby, the smell by the ammonia which generate | occur | produces from the urinal apparatus 100 can be suppressed. In addition, the region where water is not supplied can be cleaned by the first cleaning water supply unit 140.

  The amount of water supplied to the bowl part 171 by the second cleaning water supply means 160 in one operation is larger than the amount of water supplied to the bowl part 171 by the first cleaning water supply means 140 in one operation. Few. The amount of water supplied to the bowl part 171 by the second washing water supply means 160 in one operation is, for example, about 20 milliliters (mL) to about 100 mL. The amount of water supplied to the bowl portion 171 by the first cleaning water supply unit 140 in one operation is, for example, about 0.4 liter (L) or more and 1.5 L or less.

  According to this, the second cleaning water supply means 160 is a region inside the bowl portion 171 that is not cleaned by the water supplied from the first cleaning water supply means 140 (the second region 171b and the third region). 171c) can be efficiently washed with a relatively small amount of water. Therefore, water saving can be realized.

  The user's urination action is performed in the left and right central region of the bowl portion 171 so that urine does not jump out of the bowl portion 171. Therefore, a large amount of urine from the user adheres to the entire area directly below the spreader 141 attached to the upper left and right central areas of the bowl portion 171 of the urinal 170. By supplying a large amount of water entirely from the first washing water supply means 140 to the region immediately below the spreader 141 and washing away the urine from the bowl portion 171, generation of ammonia gas caused by urine can be suppressed. it can. On the other hand, scattering of urine from the user locally adheres to the region including the lateral side of the spreader 141.

  On the other hand, as shown in FIG. 4B, the spreader 141 sprinkles and supplies water near the lateral side of the spreader 141 itself, so that the lateral side of the spreader 141 can be cleaned. . For this reason, the water sprayed from the spreader 141 allows urine from the user to adhere locally and dissolve ammonia gas caused by the urine. Alternatively, the water sprayed from the spreader 141 can clean the surface of the urinal 170 in the vicinity of the spreader 141. Thereby, the smell by the ammonia which generate | occur | produces from the urinal apparatus 100 can be suppressed.

The region that is not cleaned by the water supplied from the first cleaning water supply unit 140 includes a third region 171c. The third region 171 c includes the tip portion of the lip portion 175. Urine is relatively easy to adhere to the lip portion 175.
In contrast, the second cleaning water supply means 160 can spray and supply water to the tip of the lip 175. Thereby, the smell by the ammonia which generate | occur | produces from the urinal apparatus 100 can be suppressed.

  The water supplied from the first washing water supply means 140 to the bowl portion 171 flows downward along the surface of the bowl portion 171. The water supplied from the second washing water supply means 160 to the bowl portion 171 and adhered to the surface of the bowl portion 171 flows downward along the surface of the bowl portion 171. At this time, the speed of the water supplied from the second cleaning water supply means 160 to the bowl portion 171 and transmitted through the surface of the bowl portion 171 is supplied from the first cleaning water supply means 140 to the bowl portion 171. Slower than the speed of water. The water supplied to the bowl portion 171 by the second cleaning water supply means 160 is water that has been made into droplets.

  According to this, the water supplied from the second cleaning water supply means 160 and transmitted through the surface of the bowl portion 171 is transferred to the bowl portion 171 more than the water supplied from the first supply means 140 and transmitted through the surface of the bowl portion 171. The contact time can be lengthened, and the action time on urine can be lengthened. Accordingly, the surface of the bowl portion 171 can be washed away with a relatively small amount of water, and the bowl portion 171 can be efficiently washed. Thereby, the smell by the ammonia which generate | occur | produces from the urinal apparatus 100 can be suppressed.

FIG. 5 is a schematic diagram for explaining the shape of water discharged by the second cleaning water supply means of the present embodiment.

That is, the water sprayed from the sprinkling part 161 of the second washing water supply means 160 does not proceed directly to the outside of the bowl part 171.

  Thereby, it is suppressed that the water sprinkled from the water sprinkling part 161 adheres to the outer side of the bowl part 171. FIG. Therefore, it is possible to prevent the user from getting wet or the surroundings of the urinal 170 from being wet by the water sprayed from the water sprinkling portion 161.

  As shown in FIG. 5A, the watering part 161 of the second cleaning water supply unit 160 sprinkles water toward the inside of the bowl part 171. In other words, the water sprayed from the water spraying part 161 of the second washing water supply means 160 has a direction toward the inside of the bowl part 171. Specifically, the water shaft 169 c of the conical shape 169 sprinkled from the water sprinkling part 161 of the second washing water supply means 160 faces rearward when viewed from the water sprinkling part 161.

  According to this, it is possible to further suppress the user from getting wet or the surroundings of the urinal 170 from getting wet by the water sprayed from the water sprinkling part 161. In addition, even if urine adheres to an area that is not cleaned by the water supplied from the first cleaning water supply unit 140, the second cleaning water supply unit 160 causes the urine that has adhered to the surface of the bowl portion 171 to sprinkle. The water sprayed from 161 can be washed away. Thereby, the smell by the ammonia which generate | occur | produces from the urinal apparatus 100 can be suppressed.

  The watering part 161 is an area inside the bowl part 171 of the urinal 170 and is water droplets formed in any area between the position of the user's nose facing the bowl part 171 and the trap part 173. Watering. In the present specification, the “position of the user's nose” means a position having a height in the range of about 140 centimeters (cm) to 170 cm from the floor surface 201 of the toilet room where the urinal device 100 is installed. And Note that the urinal device 100 is not necessarily placed on the floor surface 201 of the toilet room, and may be installed on a wall surface (not shown) of the toilet room. Even in this case, the “position of the user's nose” in the present specification means a position having a height in the range of about 140 centimeters (cm) to 170 cm from the floor surface 201 of the toilet room.

FIG. 6 is a schematic diagram for explaining another shape of water discharged by the second cleaning water supply unit of the present embodiment.
Fig.6 (a) is typical sectional drawing when the urinal apparatus of this embodiment is seen from the side. FIG. 6B is a schematic plan view when the water discharged by the second cleaning water supply means is viewed in the direction of the arrow B shown in FIG.

  As shown in FIG. 6A and FIG. 6B, the shape of the water discharged from the spray watering portion 161 of the second washing water supply means 160 has a sector shape 169a. The sprinkling part 161 of the second washing water supply means 160 sprinkles water toward the inside of the bowl part 171. In other words, the water sprayed from the water spraying part 161 of the second washing water supply means 160 has a direction toward the inside of the bowl part 171. Specifically, the water shaft 169 d of the fan-shaped 169 a sprayed from the water spraying part 161 of the second cleaning water supply means 160 faces substantially downward as viewed from the spray water spraying part 161. Other discharge modes are the same as those described above with reference to FIG.

  According to this, it is possible to reduce the amount of water sprayed on the wall surface of the urinal 170 (water transmitted through the surface of the bowl portion 171) and to maximize water spraying into the space. Thereby, the deodorization of the odor component existing in the space can be maximized rather than the cleaning of the ammonia generation source caused by the urine adhering to the surface of the bowl portion 171.

  According to the discharge mode shown in FIGS. 5 and 6, the water sprinkled from the sprinkler 161 dissolves ammonia generated from the trap 173. Furthermore, when the water sprayed is functional water containing hypochlorous acid, in addition to dissolving ammonia, ammonia is decomposed into odorless substances. Therefore, the user is less likely to feel the odor due to ammonia generated from the trap portion 173.

FIG. 7 is a schematic view illustrating a specific example of the first cleaning water supply unit and the second cleaning water supply unit of the present embodiment.
FIG. 7A is a schematic perspective view illustrating a specific example of the first cleaning water supply unit and the second cleaning water supply unit. FIG.7 (b) is typical sectional drawing in cut surface A1-A1 represented to Fig.7 (a). FIG.7 (c) is typical sectional drawing in cut surface A2-A2 represented to Fig.7 (a).

  In the specific examples shown in FIGS. 7A to 7C, the first cleaning water supply unit 140 and the second cleaning water supply unit 160 are integrated with each other. As shown in FIG. 7B, the first cleaning water supply unit 140 includes a spreader 141. Inside the spreader 141, a spreader flow path 143 is provided. As shown in FIG. 7B and FIG. 7C, a water outlet 145 is formed at one end of the spreader flow path 143. The water guided through the spreader channel 143 is discharged from the water outlet 145 and supplied to the bowl portion 171 of the urinal 170.

  The second washing water supply unit 160 includes a water sprinkling unit 161 and a tube 163. The watering part 161 has a nozzle etc., for example, and is connected to one end of the tube 163. The water or functional water guided through the tube 163 is sprinkled from the sprinkler 161 as dropletized water or dropletized functional water and supplied to the bowl 171 of the urinal 170.

As shown in FIG. 7A and FIG. 7B, the human body detection means 120 is provided inside the first washing water supply means and the second washing water supply means of this specific example. . The human body detection means 120 is as described above with reference to FIG.
In the present embodiment, the first cleaning water supply unit 140 and the second cleaning water supply unit 160 are not limited to being integrated with each other.

FIG. 8 is a timing chart illustrating the operation of the urinal device according to this embodiment.
First, when the human body detection unit 120 detects a user in front of the urinal 170, the control unit 110 controls the operation of the second washing water supply unit 160, and the sprinkling unit 161 of the second washing water supply unit 160. To supply water to the bowl portion 171 (timing t1). That is, the 2nd washing water supply means 160 supplies water to the bowl part 171 from the water sprinkling part 161 in the state before a user approaches the urinal 170 and uses the urinal 170 (timing t1).

  Subsequently, when the human body detection unit 120 detects a stationary user in front of the urinal 170, the control unit 110 controls the operation of the second washing water supply unit 160, and the water sprayed from the sprinkling unit 161 is discharged. Stop (timing t2). In addition, the control part 110 is sprinkled from the water sprinkling part 161 not based on the signal which the human body detection means 120 detected the user who stopped still in front of the urinal 170 but based on the amount of water sprinkled by the sprinkling part 161. Water may be stopped.

  “On” regarding the second cleaning water supply unit 160 shown in FIG. 8 indicates an operation or a state in which the second cleaning water supply unit 160 supplies water to the bowl portion 171. “OFF” regarding the second washing water supply unit 160 shown in FIG. 8 represents an operation or state in which the second washing water supply unit 160 does not supply water to the bowl portion 171.

  Subsequently, when the user finishes urination and the human body detecting means 120 detects the user moving away from the front of the urinal 170, the control unit 110 controls the operation of the first washing water supply means 140, Water is supplied from the spreader 141 of the first cleaning water supply means 140 to the bowl portion 171 (timing t3). When a predetermined amount of water is supplied to the bowl portion 171, the control unit 110 controls the operation of the first cleaning water supply unit 140 and stops the water supplied from the spreader 141 (timing t <b> 4).

  “On” regarding the first cleaning water supply unit 140 shown in FIG. 8 indicates an operation or a state in which the first cleaning water supply unit 140 supplies water to the bowl portion 171. “OFF” relating to the first cleaning water supply unit 140 shown in FIG. 8 represents an operation or state in which the first cleaning water supply unit 140 does not supply water to the bowl portion 171.

  Subsequently, when the human body detection unit 120 detects that the user is no longer in front of the urinal 170, the control unit 110 controls the operations of the functional water generation unit 150 and the second washing water supply unit 160. The functional water is generated in the functional water generating means 150, and the functional water is supplied from the sprinkling portion 161 of the second washing water supply means 160 to the bowl portion 171 (timing t5). When a predetermined amount of functional water is supplied to the bowl unit 171, the control unit 110 controls the operation of the functional water generation unit 150 and the second washing water supply unit 160, and the functional water sprayed from the water spray unit 161. Is stopped (timing t6).

  Subsequently, when a predetermined time elapses after the first cleaning water supply unit 140 supplies water to the bowl unit 171 (timing t3), the control unit 110 controls the operation of the first cleaning water supply unit 140. Then, water is supplied from the spreader 141 of the first cleaning water supply means 140 to the bowl portion 171 (timing t7). When a predetermined amount of water is supplied to the bowl portion 171, the control unit 110 controls the operation of the first cleaning water supply unit 140 and stops the water supplied from the spreader 141 (timing t <b> 8). Thereby, the sealed water inside the trap part 173 of the urinal 170 can be replaced with newly supplied water.

  The operations at timings t7 to t8 may be executed when a predetermined time has elapsed after the first cleaning water supply unit 140 supplies water to the bowl portion 171 (timing t4). Or the operation | movement of timing t7-t8 may be performed when the predetermined time passes, after the 2nd washing water supply means 160 supplies functional water to the bowl part 171 (timing t5). Or the operation | movement of timing t7-t8 may be performed when predetermined time passes, after the 2nd washing water supply means 160 supplies functional water to the bowl part 171 (timing t6).

  As described above, the timing at which the second cleaning water supply unit 160 supplies water from the sprinkling unit 161 to the bowl unit 171 to dissolve and decompose the ammonia is such that the first cleaning water supply unit 140 supplies water to the bowl unit 171. The timing is different. Thereby, the smell by the ammonia which generate | occur | produces from the urinal apparatus 100 can be suppressed efficiently.

  Further, as described above with respect to the operation at the timing t1, the second washing water supply means 160 supplies water from the water sprinkling portion 161 to the bowl portion 171 before the user approaches the urinal 170 and uses the urinal 170. Supply. Thereby, before the user approaches the urinal 170 and feels the odor due to ammonia gas, the second washing water supply means 160 can supply water to the bowl portion 171 and suppress the odor due to ammonia gas. If the number of times the urinal 170 is used exceeds a certain value, that is, if the urinal 170 is continuously used at a certain time interval, the user who uses the urinal 170, for example, performs the second cleaning by the operation at the timing t5 to t6 of the previous user. The effect of supplying the functional water from the water supply unit 160 is substantially the same as the effect of supplying the functional water from the second washing water supply unit 160 by the operation at the timings t1 to t2. Therefore, it is possible to omit either functional water supply at timings t1 to t2 and functional water supply at timings t5 to t6. Further, by omitting the supply of the functional water from the second washing water supply means 160 by the operation from t1 to t2, it is ensured that the user who uses the urinal 170 this time is sprayed with the functional water. It is preferable because it prevents water exposure.

  Note that the operation of the urinal device 100 described with reference to FIG. 8 is an example, and is not limited thereto.

Next, an example of the result of the study conducted by the present inventor will be described with reference to the drawings.
FIG. 9 is a graph showing an example of the result of the study conducted by the present inventor.
The inventor put pseudo urine (ammonia warm water) in a box having a volume of 0.6 cubic meters (m ³ ), and sprayed water and functional water into the box from a nozzle attached to the box. The inventor used a liquid containing hypochlorous acid as functional water. The concentration of hypochlorous acid is about 2.5 ppm (parts per million).

  The vertical axis of the graph shown in FIG. 9 represents the residual ratio (%) of ammonia in the box. The horizontal axis of the graph shown in FIG. 9 represents time (seconds) that has elapsed since water and functional water were sprinkled in the box. In the graph shown in FIG. 9, the residual ratio of ammonia before water and functional water are sprinkled in the box is 100 percent (%).

  The transition of the residual ratio of ammonia in the box after water and functional water are sprinkled is as shown in FIG. That is, when water is sprinkled into the box, the ammonia in the box is dissolved in the water. Moreover, when functional water is sprinkled in the box, ammonia in the box is dissolved in the functional water. Thereby, it turns out that water and functional water can dissolve and remove ammonia in a relatively short time. It can be seen that functional water can dissolve and remove a larger amount of ammonia compared to water (here, fresh water). This is because ammonia is decomposed into an odorless substance called chloramine. That is, the deodorizing effect with respect to ammonia of functional water is higher than the deodorizing effect with respect to ammonia of water (here, fresh water).

FIG. 10 is a graph showing an example of the result of another study conducted by the present inventor.
The present inventor put simulated urine (ammonia warm water) into the bowl portion 171 of the urinal 170 and performed a sensory evaluation of the level of odor generated from the bowl portion 171. Specifically, the present inventor selected seven subjects, and asked each of the seven subjects to perform sensory evaluation on the level of odor generated from the bowl portion 171 in 10 stages. The sensory evaluation is performed after the pseudo urine is placed in the bowl portion 171 of the urinal 170, after the first washing water supply means 140 supplies water to the bowl portion 171, and the second washing water supply means 160. Is after supplying water to the bowl portion 171.

  The result of this examination is as shown in FIG. That is, the water supplied from the first cleaning water supply means 140 to the bowl portion 171 wash away the urine adhering to the surface of the bowl portion 171. Thereby, the level of the odor generated from the bowl part 171 can be reduced. Further, the water supplied from the second cleaning water supply means 160 dissolves the ammonia generated in the bowl portion 171. Thereby, the level of the odor generated from the bowl part 171 can be further reduced.

FIG. 11 is a graph showing an example of the result of still another study conducted by the present inventor.
Fig.11 (a) is a typical perspective view explaining the measurement position of the density | concentration of ammonia. FIG. 11B is a graph illustrating the transition of the ammonia concentration at the first position. FIG. 11C is a graph illustrating the transition of the ammonia concentration at the second position.

  The inventor measured the concentration of ammonia in the bowl portion 171 of the urinal 170 for about two months. Specifically, the present inventor has a frequency of about 10 millimeters (mm) on the eye plate 177 provided in the bowl portion 171 at a frequency of about once a day for about two months (first Position) 177a and the concentration of ammonia at a position (second position) 175a of about 10 mm above the tip of the lip 175 were measured.

  The inventor conducted this examination using two urinals 170. In the first urinal 170a, the first washing water supply means 140 does not supply water to the bowl portion 171 and the second washing water supply means 160 has a hypochlorous acid concentration of about 2.5 ppm. Functional water is supplied to the bowl portion 171. In the second urinal 170 b, the first washing water supply unit 140 and the second washing water supply unit 160 do not supply water to the bowl portion 171.

  In the first urinal 170a, the second flushing water supply means 160 sprinkles functional water in the bowl portion 171 every time the first urinal 170a is used. The amount of water supplied to the bowl portion 171 by the second washing water supply means 160 is about 60 mL per time. The present inventor washed the first urinal 170a and the second urinal 170b with a toilet detergent before starting the examination. The inventor measured the concentration of ammonia using a detector tube.

  The transition of the ammonia concentration in the first urinal 170a and the second urinal 170b is as shown in FIG. 11 (b) and FIG. 11 (c). That is, if the first cleaning water supply means 140 and the second cleaning water supply means 160 do not supply water to the bowl portion 171, the ammonia concentration at the first position 177 a and the second position 175 a increases (first 2 urinals 170b). Further, even if the first cleaning water supply means 140 does not supply water to the bowl portion 171, the second cleaning water supply means 160 supplies water or functional water to the bowl portion 171, so that the first position 177 a. And the raise of the density | concentration of ammonia in the 2nd position 175a can be suppressed (1st urinal 170a).

FIG. 12 is a graph showing an example of the result of still another study conducted by the present inventor.
FIG. 12A is a schematic perspective view for explaining the conditions of this study. FIG. 12B is a graph showing the amount of water scattered with respect to the diameter of the dropletized water.
The vertical axis of the graph shown in FIG. 12B represents the scattering amount (scattering amount) (mL). The horizontal axis of the graph shown in FIG. 12B represents the diameter (μm) of the water droplets.

  The inventor has studied the difference in the amount of scattered water in the principle model environment due to the difference in the diameter of the dropletized water sprayed by the sprinkler 161. That is, the present inventor prepared a plate 210 having holes 211 and water sensitive paper 220. The diameter of the hole 211 is about 20 mm. As shown in FIG. 12A, the present inventor installed the watering part 161 on one side as viewed from the plate 210 and installed the water sensitive paper 220 on the other side as viewed from the plate 210. In the state shown in FIG. 12A, the present inventor sprayed water droplets from the water sprinkling portion 161 and measured the amount of water adhering to the water sensitive paper 220.

  The amount of water adhering to the water-sensitive paper 220 (amount of scattering: amount of scattering) is as shown in FIG. That is, when the diameter of the water droplets sprayed by the water sprinkling unit 161 is 10 μm or more and 1200 μm or less, the amount of water adhering to the water sensitive paper 220 is less than 1 mL. On the other hand, when the diameter of water droplets sprinkled by the water sprinkling unit 161 is 1500 μm, the amount of water adhering to the water sensitive paper 220 is 1 mL or more.

  Here, according to the knowledge obtained by the present inventor, when the amount of water adhering to the water sensitive paper 220 (spatter amount: spatter amount) is 1 mL or more, in an actual urinal installation environment, Can recognize splatters. Therefore, in order to prevent the user from recognizing the splash of water on the user or the floor, the diameter of the water droplets is preferably 1200 μm or less.

  In addition, when the diameter of the dropletized water is smaller than 10 μm, the dropletized water has a high degree of floating in the space or floating in the space. Therefore, in order to prevent the user from recognizing the splash of water on the user or the floor, the diameter of the water droplets is preferably 10 μm or more.
