Description

Technical Field

[0001] The invention relates to the technical field of decoration and renovation, and in particular to a floor drain and a bathroom floor system having the floor drain. Background Art

[0002] As is known, floor drains are used to drain water from bathrooms. In the case where a chassis is set up on the floor of the bathroom, a floor drain needs to be installed on the chassis to drain water from the chassis (ie, water on the chassis is drained away by means of the floor drain).

[0003] The floor drain in the prior art specifically generally comprises a cylindrical body and a cover assembly located at the upper end of the body. The cover assembly generally comprises a disc body, which is placed above the floor drain hole (the floor drain hole is formed on the bottom plate), and the main body is placed below the floor drain hole. The function of the disc body is:

[0004] The water on the bottom plate first passes through the plate body and then flows into the main body, that is, the water on the bottom plate enters the main body thereunder with the help of the plate body.

[0005] In the prior art, the disc is usually set to be a plate-shaped circle, and the radial dimension of the disc is inevitably set larger (relative to the radial dimension of the body) so that the disc can better play the above role. The reason is:

[0006] In the prior art, the radial dimension of the disc is set as large as possible so that the water on the bottom plate can smoothly pass through the disc into the main body to facilitate the water on the bottom plate to be drained away through the floor drain in real time.

[0007] However, the above-mentioned floor drain has the following defects:

[0008] Even if the floor drain is installed as close to the side of the chassis as possible (i.e., installed as close to the wall of the bathroom as possible), the occupants may still easily step on the relevant parts of the cover assembly, for example, the chassis (if there is no cover above the chassis), or the cover above the cover above the chassis (if there is a cover above the chassis), which may be detrimental to the use and life of the floor drain and the safety of the occupants.

DETAILED DESCRIPTION

[0069] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0070] Unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0071] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0072] Before introducing the floor drain of the present invention, the defects of the floor drain with a circular disk mentioned in the background art are further explained.

[0073] In the prior art, in order to prevent the floor drain from being frequently stepped on by the occupants, the floor drain is installed at the side position close to the chassis, that is, the floor drain is arranged at the position close to the wall 200 of the bathroom. Although this method of merely changing the layout of the floor drain does reduce the frequency of the floor drain being stepped on to a certain extent; however, since the disk body in the cover assembly 20 of the floor drain in the prior art is arranged in a circular shape (if a component such as a cover body is arranged above the disk body, such component should also be arranged in a circular shape that is at least not less than the diameter of the disk body), if Figure 1 As shown, the farthest area of ​​the tray 300 away from the wall 200 is still at a certain distance H1 from the wall 200, which results in: the probability of the part of the tray 300 away from the wall 200 being stepped on by the occupants is still very high, and this is also the case during actual use. In order to further reduce the probability of the tray 300 at this position (if there are parts such as a cover on the tray, these parts are stepped on directly, and the tray is stepped on indirectly), some technicians in the field of floor drains and bottom trays reduce the radial size of the tray 300 to reduce the distance H1 to reduce the probability of this area being stepped on. However, the tray with a reduced radial size is bound to increase the obstruction to water, resulting in the water on the bottom tray 100 not being discharged by the floor drain in real time.

[0074] like Figures 2 to 16 As shown, an embodiment of the present invention discloses a floor drain, which includes a body 10 and a cover assembly 20 .

[0075] like Figure 4 and Figure 5 As shown, the body 10 is used to be arranged below the floor drain hole 101 provided on the bottom plate 100 in the bathroom. In this embodiment, as shown in FIG. Figure 2 and Figure 3 As shown, the floor drain hole 101 is opened at a position of the bottom plate 100 near the bathroom wall 200. The body 10 may be cylindrical, and a drain pipe 13 is formed on the body 10. Water flowing through the body 10 can be discharged through the drain pipe 13. The arrangement position and manner of the drain pipe 13 may be various. In this embodiment, as shown in FIG. Fig.16 As shown, the drain pipe 13 can extend from one side of the body 10 and pass through the interior of the body 10; Figure 4 As shown, the drain pipe 13 may extend from the bottom of the body 10 and pass through the interior of the body 10 .

[0076] In this embodiment, if Figures 4 to 15 As shown, the cover assembly 20 includes a first plate 21, and the first plate 21 is placed above the floor drain hole 101. Fig.15As shown, the first plate 21 is arranged in a strip shape, and the first plate 21 is arranged parallel to the side of the chassis 100 closest to the floor drain hole 101 (or the preset wall 200 closest to the floor drain hole 101), as shown in FIG. Fig.10 As shown, a first hollow portion 211 opposite to the interior of the main body 10 is formed on the first plate body 21, and the first hollow portion 211 is used for allowing water on the chassis 100 to pass through, that is, the water on the chassis 100 enters the main body 10 through the first hollow portion 211 (the water entering the main body 10 flows through the main body 10 and is discharged with the help of the drain pipe 13).

[0077] The advantages of the above embodiment are:

[0078] The present invention sets the first plate body 21 in a strip shape, so that the first hollow portion 211 can be set in a non-circular shape, and the flow cross section (i.e., the cross section of the first hollow portion 211) that can ensure smooth passage of water can be obtained by reducing the width direction as much as possible and increasing the length direction in accordance with the first plate body 21. In this way, the distance between the farthest area of ​​the first plate body 21 and the side of the bottom plate 100 can be minimized, such as Figure 1 and Figure 2 As shown, under the condition that water can pass through the disc smoothly, the distance H2 between the farthest area of ​​the first disc 21 of the present invention and the side of the chassis 100 can be set to be much smaller than the distance H1. Therefore, compared with the disc of the chassis 100 in the prior art, the probability of the first disc 21 of the floor drain of the present invention being directly or indirectly stepped on is greatly reduced.

[0079] It should state:

[0080] 1. The indirect stepping on of the first tray 21 should be understood as follows: in some cases, the first tray 21 is arranged at the topmost layer of the floor drain cover assembly 20, and the occupant will directly step on the first tray 21; in other cases, the first tray 21 is not arranged at the topmost layer, that is, there is a component such as the decorative cover 25 described below above the first tray 21, and the occupant will directly step on the decorative cover 25, and at this time, the first tray 21 is said to be indirectly stepped on.

[0081] 2. It can be understood that if a component such as a decorative cover 25 is also provided above the first tray body 21, since the first tray body 21 is in a strip shape, it is possible to set such a component in a strip shape consistent with the first tray body 21. In this way, the frequency of being stepped on by residents can also be reduced by setting such a component in an outer size consistent with the first tray body 21.

[0082] In a preferred embodiment of the present invention, Figures 4 to 15As shown, the cover assembly 20 further includes a second plate 22, which is located below the floor drain hole 101 and corresponds to the first plate 21. Figures 6 to 9 As shown, the main body 10 is fixedly connected to the second plate 22 and is located below the second plate 22. For example, an annular slot is opened below the second plate 22, and the upper end of the main body 10 is inserted into the slot and fixed below the second plate 22 by adhesive bonding.

[0083] In this embodiment, the first plate 21 is extended at both ends in the length direction to form two first extensions 212, that is, the first extensions 212 are formed on both sides of the first hollow portion 211; the second plate 22 has a similar structure to the first plate 21, that is, a second hollow portion 224 opposite to the first hollow portion 211 is formed in the middle of the second plate 22, and the two ends of the second plate 22 are extended to form second extensions 222 located on both sides of the first hollow portion 211. The first extension 212 and the second extension 222 located on the same side are connected by fasteners, so that the chassis 100 at the periphery of the floor drain hole 101 is clamped between the first plate 21 and the second plate 22, so that the body 10 can be kept at the floor drain hole 101 and the first plate 21 and the second plate 22 can form a stable installation state.

[0084] In this embodiment, the second plate 22 is different from the first plate 21 in that: Fig.10 As shown, a covering portion 221 is formed in the middle of the second plate body 22, and the covering portion 221 has a radially extending arc edge so that the covering portion 221 can block the upper end of the main body 10. At this time, the second hollow portion 224 is opened on the covering portion 221, so that the water on the bottom plate 100 flows through the first hollow portion 211 and the second hollow portion 224 in sequence and enters the main body 10.

[0085] The advantages of the above embodiment are:

[0086] 1. The first plate 21 and the second plate 22 clamp the chassis 100 by fasteners so that the floor drain can be stably installed on the chassis 100.

[0087] 2. The extension portion extends in the length direction of the disc body and will not increase the size of the disc body in the width direction. Therefore, the probability of the disc body being directly or indirectly stepped on will not increase due to the formation of the extension portion.

[0088] In the case of using metal screws 2124 as fasteners to connect the two disk bodies, such as Figures 6 to 11As shown, in one embodiment of the present invention, a shielding and sealing structure is provided to prevent the metal screw 2124, especially the nut of the metal screw 2124, from being exposed to the outside and rusting. Specifically, a recessed groove 2121 is opened on the upper surface of the first extension portion 212, and a step surface 21211 is formed on the groove wall of the recessed groove 2121. The metal screw 2124 is arranged at the recessed groove 2121 and extends into the second extension portion 222 by passing through the first extension portion 212. A sealing gasket 2123 is placed on the step surface 21211, and a buckle cover 2122 is buckled at the recessed groove 2121 and pressed against the sealing gasket 2123. In this way, with the help of the shielding effect of the buckle cover 2122, the metal screw 2124 will not be exposed to the outside, and with the help of the sealing effect of the sealing gasket 2123, external water and even water vapor will not enter the recessed groove 2121, thereby effectively preventing the metal screw 2124, especially the nut of the metal screw 2124 located in the recessed groove 2121, from rusting.

[0089] It should be noted that in order to prevent the head of the metal screw 2124 from penetrating the second extension portion 222, a protrusion 223 is provided at the bottom of the second extension portion 222 at a position corresponding to the metal screw 2124, and the metal screw 2124 extends into the protrusion 223 without protruding out of the protrusion 223, thereby effectively preventing the metal screw 2124 from penetrating the second extension portion 222 and preventing the head of the metal screw 2124 from rusting.

[0090] In a preferred embodiment, Fig.11 As shown, the buckle cover 2122 is screwed onto the sink 2121 by means of a rotating engaging structure; and a strip-shaped force-applying groove 21221 is formed on the upper end surface of the buckle cover 2122 so that an external tool can be inserted into the force-applying groove 21221 to screw the buckle cover 2122. Specifically, the rotating locking structure includes a locking groove 21213 defined by the bottom of the groove 2121 and the protrusion 21212 arranged on the groove wall, and a wedge-shaped clamping head 21222 formed at the bottom of the buckle cover 2122; when the buckle cover 2122 is placed in the groove 2121, an external tool is extended into the force-applying groove 21221 to apply torque so that the clamping head 21222 is screwed into the locking groove 21213, thereby making the buckle cover 2122 screwed into the groove 2121 and will not fall out of the groove 2121. When the buckle cover 2122 needs to be removed, the buckle cover 2122 is rotated in the opposite direction to make the clamping head 21222 fall out of the locking groove 21213.

[0091] In a preferred embodiment of the present invention, an insert tube 214 is formed at the bottom of the first plate body 21, which is opposite to the first hollow portion 211. In a preferred solution, the insert tube 214 is integrally formed with the first plate body 21, and the insert tube 214 passes through the first hollow portion 211 and the second hollow portion 224. In this embodiment, a first sealing ring 215 is provided between the outer peripheral surface of the insert tube 214 and the side wall of the second hollow portion 224.

[0092] The advantages of the above embodiment are:

[0093] 1. By forming an insert tube 214 at the bottom of the first plate body 21 and passing through the second hollow portion 224, on the one hand, the first plate body 21 and the second plate body 22 are relatively stably positioned; on the other hand, water is effectively prevented from entering the space between the first plate body 21 and the second plate body 22 after passing through the first hollow portion 211.

[0094] 2. The first sealing ring 215 can effectively prevent the odor in the body 10 and / or the overflowing water in the body 10 from returning into the gap between the insert 214 and the second hollow portion 224 and returning into the first tray 21 and the second tray 22 and into the bathroom.

[0095] In a preferred embodiment of the present invention, the floor drain is configured to prevent the odor in the drain pipe 13 from returning to the bathroom, that is, the floor drain is configured to be an odor-proof floor drain. To this end, the body 10 is configured to include an outer tube 11 and an inner tube 12. The inner tube 12 is disposed in the outer tube 11, and the bottom of the inner tube 12 is closed. In view of the different locations and methods of the above-mentioned drain pipe 13, the inner tube 12 has different specific structures:

[0096] like Fig.16 As shown, when the drain pipe 13 extends from one side of the outer cylinder 11 and passes through the interior of the outer cylinder 11, the upper end of the outer cylinder 11 is inserted into the lower part of the sealing portion 221 of the second disk 22 and is fixedly connected to the second disk 22, and the upper end of the inner cylinder 12 is lower than the second disk 22 so that the water entering the inner cylinder 12 can flow into the gap between the upper end of the inner cylinder 12 and the sealing portion 221, and then be discharged through the drain pipe 13.

[0097] like Figures 4 to 11 As shown, when the drain pipe 13 extends from the bottom of the outer cylinder 11 and passes through the interior of the outer cylinder 11, the upper ends of the outer cylinder 11 and the inner cylinder 12 are inserted into the lower end of the sealing portion 221 of the second disk 22 and are fixedly connected to the second disk 22 at the same time. At this time, a circumferentially extending water groove 121 is opened on the cylinder wall of the inner cylinder 12 near its upper end. The water entering the inner cylinder 12 passes through the water groove 121 and flows into the space between the outer cylinder 11 and the inner cylinder 12, and then is discharged through the drain pipe 13.

[0098] It is worth noting that, in the case where the drain pipe 13 extends from one side of the outer tube 11 , the upper end of the inner tube 12 is made to be higher than the top area of ​​the drain pipe 13 as much as possible.

[0099] In this embodiment, it is necessary to add a water storage cylinder 23 to the floor drain to achieve the deodorization function. The water storage cylinder 23 is penetrated from top to bottom by the first hollow portion 211 and the insert cylinder 214 and extends into the inner cylinder 12 to a certain depth. In this way, when there is water on the bottom plate 100, the water on the bottom plate 100 flows into the inner cylinder 12 through the water storage cylinder 23 in real time. The water entering the inner cylinder 12 flows into the outer cylinder 11 from the upper end of the inner cylinder 12 (when the drain pipe 13 is formed on one side of the outer cylinder 11). Or it flows into the outer cylinder 11 from the water groove 121 of the inner cylinder 12 (when the drain pipe 13 is formed at the bottom of the outer cylinder 11), and is finally discharged from the drain pipe 13; and when there is no water passing through the water storage cylinder 23, under the holding effect of the inner cylinder 12, the water storage cylinder 23 has water at the same height as the upper end of the inner cylinder 12 or the water groove 121, and this water has the effect of blocking odor, which can prevent the odor in the drain pipe 13 from entering the bathroom through the water storage cylinder 23 to a certain extent.

[0100] In a preferred embodiment, a damping ring 233 is provided between the outer circumference of the water storage cylinder 23 and the side wall of the first hollow portion 211. Of course, the damping ring 233 can also be provided a little lower, that is, a damping ring 233 is provided between the outer circumference of the water storage cylinder 23 and the wall of the insert cylinder 214. The cross section of the damping ring 233 can be set to a rectangle, and the damping ring 233 is made of rubber material.
