Odor-proof cover

Abstract

To provide an odor-proof lid which can be easily attached to a drainage device and can prevent the diffusion of odors for a long period of time. [Solution] The Western-style toilet 100 is structured so that a certain amount of water is stored in the water pool 101 by providing a weir 105. By providing the weir 105, the drainage path of the drainage channel 120 is blocked by the water stored in the water pool 101. This blocks the odor rising from the drainage channel 120. When the level of the water stored in the water pool 101 drops for some reason, the water pool 101 and the drainage channel 120 are directly connected without water being interposed, and the odor reaches the water pool 101 via the drainage channel 120 and is diffused to the outside. The odor-proof lid 1 covers the upper part of the wall surface 102 that defines the water pool 101 of the Western-style toilet 100 while in contact with it, thereby suppressing the evaporation of the water stored in the weir 105, and includes a contact part 10, a cover part 20, and a support part 30.

Description

[Technical field]

[0001] The present invention relates to an odor-proof cover that prevents odors from being generated from a drainage device. [Background technology]

[0002] When a resident is away for an extended period of time, or for some other reason goes unusable for a long period of time, the water stored in the toilet bowl evaporates, causing odors to rise up the drain and disperse through the trap to the outside. Also, when water stored in the trap of the sink evaporates, odors rise up the drain and disperse through the trap to the outside, causing odors to permeate the room.

[0003] In this case, residents will feel uncomfortable when they enter the room. It is necessary to take measures such as ventilating the room to get rid of the odor. Even if the odor that fills the room is expelled to the outside through ventilation, it will not disappear completely as it will permeate the walls and furnishings, and it is possible that residents will feel uncomfortable for a long time afterwards.

[0004] Patent Document 1 proposes a toilet deodorizing plug. This toilet deodorizing plug is composed of a lid part having a diameter larger than the diameter of the opening of the toilet bowl part, and an elastically deformable material that closes the opening. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7371994 Summary of the Invention [Problem to be solved by the invention]

[0006] The odor-proof plug proposed in Patent Document 1 can block an opening by applying force to the plug and inserting it into the opening. Therefore, if the direction of the force is not appropriate, it may be difficult to insert the plug into the opening. Also, if a gap occurs between the opening and the plug for some reason, water may evaporate from the gap.

[0007] The present invention has been made with attention to these problems, and aims to provide an odor-proof cover that can be easily attached and can prevent the diffusion of odors for a long period of time. [Means for solving the problem]

[0008] The invention for solving the above problems is an odor-proof lid for use in a drainage device that has the function of preventing the diffusion of odors by utilizing stored water, and is characterized in that it comprises a contact portion having a ring-shaped swelling portion that has swelling performance, a membrane-shaped cover portion that covers the internal area of ​​the contact portion, and a support portion that is connected to the contact portion and supports the cover portion, and is characterized in that the evaporation of water stored in the drainage device can be suppressed by the swelling portion coming into contact with a wall surface provided on the inner side of the drainage device.

[0009] According to this configuration, the swelling portion comes into contact with the wall surface provided on the outer periphery of the drain outlet, so that the upper part of the drain outlet is covered with the cover portion. Therefore, even if the water stored in the drain device evaporates, it remains in the space defined by the odor-proof lid and the wall surface, and does not leak to the outside. Since the odor-proof lid can prevent the water stored in the drain device from evaporating, odors do not diffuse to the outside via the drain outlet. In addition, even if a gap occurs between the wall surface and the contact portion for some reason, and the water stored in the drain device diffuses to the outside through the gap, the swelling portion absorbs the water and swells to fill the gap. As a result, the diffusion of the water stored in the drain device to the outside can be suppressed.

[0010] Preferably, the contact portion has an annular holding portion for holding the swelling portion.

[0011] According to this configuration, since the contact portion has an annular holding portion that holds the swollen portion, the shape of the swollen portion can be stably maintained.

[0012] Preferably, the support portion has a first support portion extending in a first direction and having both ends connected to the holding portion, and a second support portion extending in a second direction intersecting the first direction and having both ends connected to the holding portion.

[0013] According to this configuration, the support portion has a first support portion extending in a first direction and having both ends connected to the holding portion, and a second support portion extending in a second direction intersecting the first direction and having both ends connected to the holding portion, so that the cover portion covering the internal area of ​​the contact portion can be stably supported.

[0014] Preferably, the first support has a first bar member having a convex arc shape, and the second support The part , convex Bow Shape The first rod member and the second rod member are connected at a position where they intersect in a plan view.

[0015] According to this configuration, the first support portion has a first rod member having a convex bow shape, and the second support The part , convex Bow Shape Since the first rod member and the second rod member are connected at a position where they intersect in a planar view, the first rod member and the second rod member mutually restrict displacement under load, and therefore the convex bow shape can be stably maintained.

[0016] Preferably, a weight is attached to the cover portion, and the swelling portion is pressed against the wall surface by the weight via the support portion.

[0017] According to this configuration, the cover portion has a weight attached thereto, and the swelling portion is pressed against the wall surface by the weight via the support portion, so that the adhesion between the swelling portion and the wall surface can be further improved.

[Diagram 3] 3 is a cross-sectional view taken along the line AA in FIG. 2. [Figure 4] 3 is a cross-sectional view taken along the line BB in FIG. 2. [Diagram 5] 1 is a schematic front cross-sectional view of the odor-proof lid installed on a washbasin. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the odor-proof lid of the present invention will be described in detail with reference to Figs.

[0020] As shown in Fig. 1, the odor-proof lid 1 is dome- or basket-shaped, and covers the upper part of a Western-style toilet 100 serving as a drainage device while contacting the inner peripheral wall surface 102 that defines a water pool 101. This suppresses loss of water stored in the weir 110 due to evaporation, and prevents odors from rising from the drainage channel 120 and diffusing to the outside for a long period of time. Such an odor-proof lid 1 includes a contact portion 10, a cover portion 20, and a support portion 30. In this embodiment, a Western-style toilet 100 is shown as an example of a drainage device, but the present invention is not limited to this.

[0021] The Western-style toilet 100 is structured so that a certain amount of water is stored in the puddle 101 by providing a weir 110 in the drainage channel 120. When water is supplied to the puddle 101, the water level of the water stored in the puddle 101 rises and flows out into the drainage channel 120 via the weir 110. By providing the weir 110, the drainage path of the drainage channel 120 is blocked by the water stored in the puddle 101. This blocks the odor rising from the drainage channel 120. Therefore, when the level of the water stored in the puddle 101 drops for some reason, the puddle 101 and the drainage channel 120 are directly connected without water being interposed, and the odor from the outflow sewer pipe 105 rises up through the drainage channel 120 to the puddle 101, and is diffused from inside the Western-style toilet I00 to the outside.

[0022] The contact portion 10 of the odor-proof lid 1 is an annular member, and is in close contact with the wall surface 102 located in the outer region of the water stored in the puddle portion 101. The inner region of the contact portion 10 is covered with the cover portion 20. The cover portion 20 is a membrane-shaped sheet-like member that covers the inner region of the contact portion 10 and can be expanded into a dome shape, and the outer peripheral edge is connected to the contact portion 10, and the inner region is supported by the support portion 30. In addition, a weight WT is attached near the top of the center of the odor-proof lid 1. The weight WT is attached with a handle WT1 for holding. The material of the cover portion 20 is preferably a sheet material that is difficult for water vapor to pass through and has high airtightness. In addition, the material of the weight WT is preferably one that is difficult to change over time and has a large specific gravity. For example, stainless steel is exemplified, but is not limited to this. The weight WT may be a separate object attached to the cover portion 20, or may be formed integrally with the cover portion 20 by insert molding or the like.

[0023] 2, the support part 30 has a first support part 31 extending in a first direction D1 and a second support part 32 extending in a second direction D2. Both ends of the first support part 31 and the second support part 32 are connected to the holding part 12 described below. In addition, the center part of the support part 30 supports the cover part 20. Here, the first direction D1 is a direction intersecting the second direction D2.

[0024] The first support part 31 has a first rod member 41 having a convex arch shape. The second support part 32 has a second rod member 42 having a convex arch shape. The first rod member 41 and the second rod member 42 are preferably composed of at least two members. In this embodiment, the number of the first rod member 41 and the second rod member 42 is illustrated as three, but is not limited to this. The number of the first rod member 41 and the second rod member 42 may be one or three or more. In this embodiment, the first rod member 41 and the second rod member 42 are illustrated as being perpendicular to each other in a plan view, but are not limited to this. The angle at which the first rod member 41 and the second rod member 42 intersect is preferably 70 degrees to 90 degrees in a plan view. More preferably, it is 80 degrees to 90 degrees.

[0025] In addition, in this embodiment, the second rod member 42 is located below the first rod member 41 (in the direction approaching the contact portion 10), but this is not limited to this. The second rod member 42 may be located above the first rod member 41.

[0026] The first rod member 41 and the second rod member 42 are preferably made of a lightweight and highly elastic material, for example, fiberglass rod members.

[0027] As shown in Fig. 3, the contact portion 10 has a swelling portion 11 and a retaining portion 12. The swelling portion 11 is an annular portion that can be in close contact with the wall surface 102, and is retained by the retaining portion 12 over its entire circumference. The retaining portion 12 is an annular portion that retains the swelling portion 11 over its entire circumference, and supports a first rod member 41 and a second rod member 42. In order to integrate the swelling portion 11 and the retaining portion 12, it is preferable to have a structure in which a portion of the swelling portion 11 is fitted into a groove portion 12a provided in the retaining portion 12 over its entire circumference.

[0028] The swelling portion 11 is preferably made of a material that has plasticity and swells by absorbing moisture. By having plasticity, the swelling portion 11 can adhere closely to the wall surface 102 while following the uneven surface of the wall surface 102. In addition, even if a gap occurs between the wall surface 102 and the swelling portion 11 due to some factor due to swelling by absorbing moisture, the swelling portion 11 absorbs moisture and swells in the process in which the water stored in the puddle portion 101 evaporates from the gap and diffuses to the outside, so that the gap is naturally filled and disappears, and the swelling portion 11 adheres closely to the wall surface 102. Examples of the material of the swelling portion 11 include a material containing a water-absorbent resin and a water-swellable plastic water-stop material containing bentonite, but are not limited thereto.

[0029] The retaining portion 12 preferably has the rigidity to maintain the predetermined annular shape. It also preferably has some plasticity, which allows it to accommodate precision errors due to individual differences in toilets and changes in the attachment position of the odor prevention lid 1 to the toilet.

[0030] 4, the first rod member 41 and the second rod member 42 are connected via a connecting member 45 at a position where they intersect in a plan view. The connecting member 45 is a cross-shaped cross member, and is provided with a first fitting recess 51 and a second fitting recess 52. The first rod member 41 and the second rod member 42 are connected via the connecting member 45 by fitting the first rod member 41 into the first fitting recess 51 and fitting the second rod member 42 into the second fitting recess 52.

[0031] The use of the odor-proof lid 1 with the Western-style toilet 100 will now be described.

[0032] When the Western-style toilet 100, washbasin, etc. are not used for a long period of time for some reason, such as being away from home for an extended period of time, the water stored in the water pool 101 of the Western-style toilet 100 evaporates, causing odors to rise up the drainage channel 120 and diffuse to the outside via the weir 105. Also, the water stored in the trap pipe of the washbasin, etc. evaporates, causing odors to rise up the drainage channel 120 and diffuse to the outside via the trap pipe. The odor-proof lid 1 prevents the odors from diffusing to the outside by suppressing the evaporation of the water stored in the water pool 101 and the trap pipe.

[0033] The handle WT1 is grasped to place the odor-proof lid 1 on the water pool 101 of the Western-style toilet 100. At this time, the annular swelling portion 11 comes into contact with the wall surface 102 of the water pool 101. At the same time, due to the effect of the weight WT attached to the cover portion 20, the weight load of the weight WT is transmitted to the swelling portion 11 of the contact portion 10 via the first and second support portions 31 and 32. As a result, the swelling portion 11 comes into airtight contact with the wall surface 102 while being pressurized and urged by the weight load from the weight WT. Therefore, even if a gap occurs between the wall surface 102 and the swelling portion 11 for some reason, the gap can be filled and sealed, or made extremely small.

[0034] When the odor prevention lid 1 is installed in the Western-style toilet 100 (see FIG. 1), the upper part of the water pool 101 is covered with the cover part 20. In other words, the space above the water pool 101 is completely sealed airtight by the cover part 20.

[0035] When a gap occurs between the wall surface 102 and the swelling portion 11, either from the beginning of installation or for some reason, the water stored in the puddle portion 101 (stored water 101A) will evaporate from the gap. At this time, the swelling portion 11 absorbs the evaporated water and swells, thereby filling the gap. As a result, loss of the water stored in the puddle portion 101 (stored water 101A) due to evaporation can be effectively suppressed. Furthermore, the water discharged from the swelling portion 11 due to evaporation is blocked by the cover portion 20, so it is prevented from rising and does not diffuse upward to the outside.

[0036] The water (reserved water 101A) stored in the water pool 101 can be prevented from disappearing because evaporation is suppressed for a long period of time by the installation of the odor prevention lid 1. As a result, the emission of odor from the stagnation 105 can be prevented.

[0037] This embodiment is an example, and it goes without saying that modifications can be made without departing from the technical spirit of the present invention. In this embodiment, a Western-style toilet is exemplified as the drainage device, but it may be a Japanese-style toilet, or may be a washbasin 200 as shown in FIG. 5. It may also be a sink. In addition, the odor-proof cover 1 is not limited to being dome-shaped or basket-shaped, and may be hat-shaped, polygonal, or flat, and the point is that it may be anything that can bring the swelling portion 11 of the holding portion 12 into close contact with the wall surface 102.

[0038] When the odor-preventing lid 1 is used for the washbasin 200, it is sufficient to install the swelling portion 11 so that it is in close contact with the wall surface 202 of the bowl 201. The installation of the odor-preventing lid 1 suppresses evaporation of the water stored in the trap pipe 210 for a long period of time, and thus the loss of the water can be prevented. As a result, the emission of odor from the trap pipe 210 can be prevented. I do. Well In addition, the odor-proof cover 1 can also be used for a sink having a trap pipe.

[0039] When used on a washbasin or sink, the installation procedure can be almost the same, so an explanation of the installation procedure will be omitted. [Industrial Applicability]

[0040] The odor-proof cover 1 according to the present invention can keep the living space of a rental apartment in a comfortable state even when the occupants are absent for a certain period of time. This makes it easier to manage rental apartments, and has great industrial applicability. [Explanation of symbols]
