Description

Technical Field

[0001] The utility model relates to the technical field of washing machine accessories, in particular to an anti-odor and anti-backflow joint for a washing machine floor drain pipe. Background Art

[0002] The washing machine floor drain, that is, the washing machine drainage floor drain, is an important interface connecting the drainage pipe system and the indoor floor. As an important component of the drainage system in the house, its performance directly affects the indoor environmental quality and air quality. At present, the washing machine floor drain is usually used in conjunction with a three-way joint. However, the three-way joint in the prior art has the following problems:

[0003] At present, the three-way joint in the prior art does not have a blocking valve, which may cause the odor in the floor drain or sewer to enter the washing machine or the room from the washing machine pipe through the joint. The three-way joint or multi-way joint may cause water and odor to leak between two or more washing machines when draining water. If the pipe is blocked, the backflow caused by the backflow will also flow back into the washing machine through the joint or the tee. Therefore, we propose an anti-odor and anti-backflow joint for the washing machine floor drain pipe to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an anti-odor and anti-backflow joint for a washing machine floor drain pipe, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: an anti-odor and anti-backflow joint for a washing machine floor drain pipe, comprising a joint pipe, one end of which is fixedly mounted with a reducer, both ends of the joint pipe are provided with connecting components, and one end of the two connecting components is provided with an anti-odor component;

[0006] The connection assembly comprises two conical sleeves, one end of each of the two conical sleeves is movably sleeved with a sealing ring, the sealing ring is movably plugged with one end of the joint pipe, and one end of each of the two conical sleeves away from the sealing ring is movably sleeved with an elastic gasket;

[0007] The deodorizing assembly comprises two cover plates, one end of the two conical sleeves is fixedly mounted with an inner tube, one end of the two inner tubes away from the conical sleeves is fixedly mounted with a top block, and the cover plates and the top block are hinged.

[0008] As a preferred technical solution of the utility model, a limiting disk is fixedly installed at one end of the two conical sleeves, and one side of the limiting disk is in active contact with one end of the joint pipe.

[0009] As a preferred technical solution of the utility model, a cap is fixedly installed on the outer wall of the reducer.

[0010] As a preferred technical solution of the utility model, the outer walls of the two conical sleeves are both provided with an annular groove.

[0011] As a preferred technical solution of the utility model, one side of the cover plate is fitted with one side of the inner tube, and the cover plate and the top block are in an inclined shape.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The washing machine drain pipe is sleeved on the outer wall of the conical sleeve, and the inner wall of the elastic gasket is in contact with the outer wall of the washing machine drain pipe. The elastic force of the elastic gasket fixes the washing machine drain pipe on the outside of the conical sleeve. At the same time, the conical surface design of the conical sleeve facilitates the connection of washing machine drain pipes of different diameters, thereby conveniently realizing the fixed connection between the washing machine drain pipe and the joint pipe, thereby effectively improving the convenience of fixing the washing machine drain pipe;

[0014] 2. When the water in the washing machine drain pipe enters the inner pipe through the joint pipe, the water pressure causes the cover plate to flip open. When the washing machine drain pipe stops draining water, the cover plate flips back and returns to its original state, thus forming a closed odor-proof space, thereby preventing flying insects and odors in the floor drain from entering the washing machine or the room, and preventing water from backflowing when the washing machine drain pipe drains water.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1-3 As shown, the utility model provides an anti-odor and anti-backflow joint for a floor drain pipe of a washing machine, comprising a joint pipe 1, one end of which is fixedly mounted with a reducer 11, both ends of the joint pipe 1 are provided with connecting components 2, one end of the two connecting components 2 are provided with an anti-odor component 3, the connecting component 2 can conveniently realize the connection between the joint pipe 1 and the drain pipe of the washing machine, the anti-odor component 3 can prevent flying insects and odors in the floor drain or sewer from entering the washing machine or the room, and at the same time prevent the backflow of water when the drain pipe of the washing machine is discharged;

[0021] The connecting assembly 2 includes two conical sleeves 21, one end of each of the two conical sleeves 21 is movably sleeved with a sealing ring 23, and the sealing ring 23 is movably plugged with one end of the joint pipe 1, and one end of each of the two conical sleeves 21 away from the sealing ring 23 is movably sleeved with an elastic gasket 25. By inserting the sealing ring 23 at the end of the conical sleeve 21 into the inner wall of the joint pipe 1, the outer wall of the sealing ring 23 fits with the inner wall of the joint pipe 1. Since the sealing ring 23 has a certain elasticity, the conical sleeve 21 and the joint pipe 1 are connected by their own tension, thereby conveniently realizing the connection between the conical sleeve 21 and the joint pipe 1. When the external washing machine drain pipe is sleeved on the outer wall of the conical sleeve 21, the inner wall of the elastic gasket 25 is sleeved on the outer wall of the washing machine drain pipe by moving the elastic gasket 25, so that the washing machine drain pipe can be fixed to the outside of the conical sleeve 21, thereby realizing the connection between the washing machine drain pipe and the joint pipe 1;

[0022] The deodorizing component 3 includes two cover plates 33. The inner tube 31 is fixedly installed at one end of the two conical sleeves 21. The top block 32 is fixedly installed at the end of the two inner tubes 31 away from the conical sleeves 21. The cover plates 33 and the top blocks 32 are hinged. The length of the upper end of the inner tube 31 is smaller than the length of the lower end. When water in the drain pipe of the washing machine enters the interior of the inner tube 31, the water pressure causes the cover plates 33 to flip open. When the drain pipe of the washing machine stops draining water, the cover plates 33 flip back and return to the initial state, thereby forming a closed deodorizing space.

[0023] Furthermore, a limit plate 22 is fixedly installed at one end of each of the two conical sleeves 21, and one side of the limit plate 22 is in movable contact with one end of the joint pipe 1. When the conical sleeve 21 and the joint pipe 1 are connected, the limit plate 22 can limit the horizontal position of the conical sleeve 21.

[0024] Furthermore, a cover cap 12 is fixedly mounted on the outer wall of the reducer 11 . When the reducer 11 is vertically inserted into the floor drain, the cover cap 12 can cover the edge of the floor drain.

[0025] Furthermore, the outer walls of the two conical sleeves 21 are each provided with an annular groove 24. By providing the annular groove 24, the tightness of the conical sleeve 21 and the external washing machine drain pipe can be improved. At the same time, the design of the conical sleeve 21 can facilitate the connection of washing machine drain pipes of different diameters.

[0026] Furthermore, one side of the cover plate 33 is in contact with one side of the inner tube 31 , and the cover plate 33 and the top block 32 are in an inclined shape.

[0027] Working principle: When using the device, the user first vertically inserts the end of the reducer 11 into the floor drain, and the lower end of the cap 12 contacts the ground and covers the floor drain. (It should be noted that when only one washing machine drain pipe is connected, an external sealing plug is used to block the end of a conical sleeve 21);

[0028] Subsequently, the two elastic washers 25 are moved horizontally, and the two elastic washers 25 move toward each other along the outer walls of the corresponding conical sleeves 21 and toward one end of the connecting pipe 1, and then the two washing machine drain pipes are respectively sleeved on the outer walls of the two conical sleeves 21. After the sleeve connection is completed, the two elastic washers 25 are moved in the opposite direction to make the inner walls of the two elastic washers 25 contact with the outer walls of the two washing machine drain pipes. Since the two elastic washers 25 have a certain elasticity, the two washing machine drain pipes are fixed to the outside of the two conical sleeves 21 through the elastic force of the two elastic washers 25. At the same time, the conical surface design of the two conical sleeves 21 is convenient for connecting washing machine drain pipes of different diameters, thereby conveniently realizing the fixed connection between the washing machine drain pipe and the connecting pipe 1, thereby effectively improving the convenience of fixing the washing machine drain pipe.

[0029] When the water in the drain pipes of the two washing machines enters the interior of the two inner tubes 31 through the joint pipe 1, the water pressure causes the two cover plates 33 to flip open. When the drain pipes of the washing machines stop draining water, the two cover plates 33 flip in the opposite direction and return to their initial states, thereby forming a closed odor-proof space, thereby preventing flying insects and odors in the floor drain from entering the washing machine or the room, and preventing water from flowing back when the drain pipes of the washing machines drain water.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
