Deodorization cover

Abstract

To provide a deodorization cover that can be easily attached to a drainage device and can prevent the diffusion of odors for a long period of time.SOLUTION: A western-style toilet 100 is structured so that a certain amount of water is stored in a puddle section 101 by providing a weir 105. By providing the weir 105, the drainage path of a drainage channel 120 is blocked by the water stored in the puddle section 101. This blocks odors rising from the drainage channel 120. If the level of water stored in the puddle section 101 drops for some reason, the puddle section 101 and the drainage channel 120 are directly connected without water intervening, and the odor reaches the puddle section 101 via the drainage channel 120 and is diffused to the outside. A deodorization cover 1 covers the upper part of a wall surface 102 that defines the puddle section 101 of the western-style toilet 100 while in contact with it, thereby preventing evaporation of water stored in the weir 105, and is equipped with a contact part 10, a cover part 20, and a support part 30.SELECTED DRAWING: Figure 1

Description

[Technical Field]

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

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

[0003] In this case, residents will feel uncomfortable when they enter the room. Also, measures such as ventilation must be taken to eliminate the odor. Even if the odor that fills the room is expelled outside through ventilation, the odor will permeate the walls and furnishings and will not be completely eliminated, and it is possible that residents will feel uncomfortable for a long time afterwards.

[0004] Patent Document 1 proposes a toilet odor prevention plug. This toilet odor prevention plug is composed of a lid with a diameter larger than the diameter of the opening of the toilet bowl, 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 close 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. Furthermore, if a gap occurs between the opening and the plug for some reason, water may evaporate from the gap.

[0007] The present invention addresses these problems and provides 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 to solve the above problem is an odor-proof lid for use in a drainage device that has the function of preventing the spread of odors by utilizing stored water, and is characterized by comprising a contact portion having a ring-shaped swelling portion with swelling properties, 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 swelling portion comes into contact with a wall surface provided on the inner side of the drainage device, thereby suppressing the evaporation of water stored in the drainage device.

[0009] With this configuration, the swelling portion contacts the wall surface surrounding the drain outlet, thereby covering the upper portion of the drain outlet with the cover portion. Therefore, even if the water stored in the drainage device evaporates, it remains in the space defined by the odor-proof lid and the wall surface and does not leak to the outside. Because the odor-proof lid prevents the water stored in the drainage device from evaporating, odors do not diffuse to the outside via the drain outlet. Furthermore, even if a gap develops between the wall surface and the contact portion for some reason and the water stored in the drainage device diffuses to the outside through that gap, the swelling portion absorbs the water and swells to fill the gap. As a result, the diffusion of water stored in the drainage device to the outside can be suppressed.

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

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

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

[0013] According to this configuration, the support portion has a first support portion that extends in a first direction and has both ends connected to the holding portion, and a second support portion that extends in a second direction that intersects the first direction and has both ends connected to the holding portion, so that the cover portion that covers the internal region of the contact portion can be stably supported.

[0014] Preferably, the first support portion has a first rod member having a convex arch shape, and the second support member has a second rod member which is also a convex rod member, and 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 member has a first rod member that is convexly bow-shaped, and the second support member has a second rod member that is also a convexly bow-shaped member.The first rod member and the second rod member are connected at a position where they intersect in a planar view, so that the first rod member and the second rod member mutually restrict displacement under load, thereby enabling the convexly bow-shaped member to 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 weight is attached to the cover portion, and the swelling portion is pressed against the wall surface by the weight via the support portion, thereby further increasing the adhesion between the swelling portion and the wall surface.

[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 Figure 1, the odor-proof lid 1 is dome- or basket-shaped and covers the upper side while contacting the inner peripheral wall surface 102 that defines the water pool 101 of a Western-style toilet 100 serving as a drainage device. This suppresses the loss of water stored in the weir 110 due to evaporation, and prevents odors from rising up the drainage channel 120 and attempting to diffuse to the outside for a long period of time. The odor-proof lid 1 comprises a contact portion 10, a cover portion 20, and a support portion 30. In this embodiment, a Western-style toilet 100 is used 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 water pool 101 by providing a weir 110 in the drainage channel 120. When water is supplied to the water pool 101, the water level in the water pool 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 water pool 101. This blocks odors rising from the drainage channel 120. Therefore, if the level of 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 from the outflow sewer pipe 105 reaches the water pool 101 via the drainage channel 120 and rises up, causing it to be diffused from inside the Western-style toilet 100 to the outside.

[0022] The contact portion 10 of the odor-proof lid 1 is an annular member that corresponds to and adheres to a wall surface 102 located in the outer region of the water stored in the puddle portion 101. The interior region of the contact portion 10 is covered by a cover portion 20. The cover portion 20 is a membrane-like sheet-like member that covers the interior region of the contact portion 10 and can be unfolded into a dome shape. The outer peripheral edge is connected to the contact portion 10, and the interior region is supported by a support portion 30. A weight WT is attached near the top of the center of the odor-proof lid 1. The weight WT is equipped with a handle WT1 for gripping. The cover portion 20 is preferably made of a sheet material that is impermeable to water vapor and has high airtightness. The weight WT is preferably made of a material that is resistant to deterioration over time and has a high specific gravity. For example, stainless steel is exemplified, but is not limited to this. The weight WT may be a separate component 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 end parts of the first support part 31 and the second support part 32 are connected to the holding part 12, which will be described later. The center part of the support part 30 supports the cover part 20. Here, the first direction D1 is a direction that intersects with the second direction D2.

[0024] The first support portion 31 has a first rod member 41 that is convexly arched. The second support portion 32 has a second rod member 42 that is also convexly arched. 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 first rod members 41 and second rod members 42 is illustrated as three, but this is not limited thereto. The number of first rod members 41 and second rod members 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 orthogonal to each other in a plan view, but this is not limited thereto. The angle at which the first rod member 41 and the second rod member 42 intersect is preferably 70 to 90 degrees in a plan view. More preferably, it is 80 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 limitative. The second rod member 42 may also 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, glass fiber rod members.

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

[0028] The swelling portion 11 is preferably made of a material that has plasticity and swells when it absorbs moisture. By having plasticity, it can adhere closely to the wall surface 102 while conforming to the uneven surface of the wall surface 102. Furthermore, even if a gap occurs between the wall surface 102 and the swelling portion 11 due to swelling when it absorbs moisture, the gap is naturally filled and disappears as the water stored in the puddle portion 101 evaporates from the gap and diffuses to the outside, and the swelling portion 11 adheres closely to the wall surface 102. Examples of the material for the swelling portion 11 include, but are not limited to, a material containing a water-absorbent resin and a water-swellable plastic water-stop material blended with bentonite.

[0029] The retaining portion 12 preferably has enough 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 in a Western-style toilet 100 will now be described.

[0032] When the Western-style toilet 100, sink, etc. are not used for an extended period of time for some reason, such as when the residence is left unattended for an extended period of time, the water stored in the water reservoir 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, when the water stored in the trap pipe of the sink, etc. evaporates, odors rise up the drainage channel 120 and diffuse to the outside via the trap pipe. The odor-proof lid 1 prevents the odor from diffusing to the outside by suppressing the evaporation of water stored in the water reservoir 101 and trap pipe.

[0033] The handle WT1 is grasped to place the odor-proof lid 1 on the water basin 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 basin 101. At the same time, due to the effect of the weight WT attached to the cover portion 20, the weight 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 receives the weight load from the weight WT and is pressurized and biased, coming into airtight contact with the wall surface 102. 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-proof 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 airtightly sealed 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 through the gap. At this time, the swelling portion 11 absorbs the evaporating 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 reservoir 101 can be prevented from disappearing because evaporation is suppressed for a long period of time by the installation of the odor-proof lid 1. As a result, the emission of odor from the weir 105 can be prevented.

[0037] This embodiment is merely 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 used as an example of the drainage device, but it may also be a Japanese-style toilet, or as shown in FIG. 5, it may also be a washbasin 200. It may also be a sink. Furthermore, the odor-proof lid 1 is not limited to being dome-shaped or basket-shaped, but may also be hat-shaped, polygonal, or flat, and the point is that it may be anything that allows the swelling portion 11 of the holding portion 12 to be in close contact with the wall surface 102.

[0038] When using the odor-proof lid 1 on the sink 200, it is sufficient to install the swelling portion 11 in close contact with the wall surface 202 of the bowl 201. The installation of the odor-proof lid 1 prevents the water stored in the trap pipe 210 from evaporating over a long period of time, thereby preventing the water from being lost. As a result, the emission of odors from the trap pipe 210 can be prevented. The odor-proof lid 1 can also be used on sinks that have a trap pipe.

[0039] When using it on a washbasin or sink, the installation procedure can be done in almost the same way, so we will omit the explanation of the installation procedure. [Industrial Applicability]

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