Technical Field

[0001] The utility model relates to the technical field of toilet doors, in particular to a toilet door. Background Art

[0002] The bathroom door is an important part used to separate the bathroom from the outside space. The door panel makes the bathroom a private space. In existing families, glass sliding doors and wooden doors are generally used as bathroom doors according to the size of the space. Nowadays, through the popularization of fire awareness, people know that when a fire occurs in a high-rise building, if there is thick smoke outside the door, escaping directly outside is likely to cause smoke to enter the body and cause suffocation, thus endangering life. In this case, the best way for residents to hide in the bathroom, plug the gap of the bathroom door with a wet towel, and wait for rescue is;

[0003] The wooden doors and glass doors used in existing bathrooms are easy to burn and have poor sealing performance. If a fire breaks out outside and the smoke density is high, the bathroom door cannot effectively block the fire source or the smoke.

[0004] Therefore, in view of the problems that the existing bathroom doors have a single structure, are easy to burn, have poor sealing performance, and cannot effectively block fire sources and thick smoke, a bathroom door with optimized structure is designed to solve the above problems, which can effectively block fire sources and thick smoke when a fire occurs and turn the bathroom into a favorable survival space. Utility Model Content

[0035] See also Figure 1-Figure 7 As shown;

[0036] A toilet door, comprising:

[0037] A door frame 1 and a door panel 2 which are matched and have the same internal structure are installed by hinges;

[0038] The door frame 1 and the door panel 2 are covered with a wooden board portion 3;

[0039] The aluminum plate part 4 is fitted inside the wooden plate part 3;

[0040] The wooden board part 3 and the aluminum board part 4 enclose and form an internal hollow installation space;

[0041] An intumescent fireproof cotton block 5 and a heat insulation board 6 are installed in the installation space;

[0042] A fire-receiving cavity 7 is formed between the intumescent fireproof cotton block 5 and the aluminum plate portion 4;

[0043] A back-fire cavity 8 is formed between the heat insulation board 6 and the aluminum plate portion 4 .

[0044] The inner wall of the door frame 1 is provided with a groove 11;

[0045] A sealing strip 9 is installed around the outer wall of the door panel 2 corresponding to the inner wall of the door frame 1;

[0046] The door panel 2 and the door frame 1 are closed to form a sealing strip 9 which is embedded in the groove 11 .

[0047] The groove 11 extends inwardly to the intumescent fireproof cotton block 5;

[0048] The intumescent fireproof cotton block 5 expands when encountering fire and increases in volume to fill the groove 11 to prevent flames and smoke from entering.

[0049] Specifically, the door frame 1 and the door panel 2 of the bathroom door are installed by hinges. After installation, a gap will be generated between the door frame 1 and the door panel 2. When a fire occurs, smoke can easily enter the bathroom through the door gap. Therefore, the outer circumference of the door frame 1 and the inner circumference of the door panel 2 are sealed. Specifically, a groove 11 is provided on the outer circumference of the door frame 1, and a sealing strip 9 is installed on the outer circumference of the door panel 2. When the door frame 1 and the door panel 2 are closed, the sealing strip 9 is embedded in the groove 11, and the gap between the door frame 1 and the door panel 2 is filled, thereby forming a closed space inside the bathroom.

[0050] Among them, the door frame 1 and the door panel 2 are optimized in terms of installation structure and material. Taking the door panel 2 as an example, the outermost part of the door panel 2 is a wooden board part 3, and the wooden board part 3 is a wooden structure, so that the door panel 2 is the same as a conventional door in appearance and conforms to the home decoration style; the wooden board part 3 is covered on the outermost part, and aluminum board parts 4 are installed on both sides of its interior. The two sides inside the wooden board part 3 are one side and the other side close to the inside of the bathroom. The aluminum board part 4 is made of aluminum board, which can not only play a supporting role, but also is more fireproof than the wooden structure. For the bathroom door, non-combustible or non-flammable aluminum board is selected; an intumescent fireproof cotton block 5 and a heat insulation board 6 are installed between the two groups of aluminum board parts 4, and a fire cavity 7 is formed between the aluminum plate close to the outside and the intumescent fireproof cotton block 5 That is, the fire source attacks from the direction of the fire cavity 7. When the fire source transfers heat to the expandable fireproof cotton block 5 through the wooden board part 3 and the aluminum plate part 4, the expandable fireproof cotton block 5 gradually expands to the surroundings, and the expandable fireproof cotton block 5 gradually fills the fire cavity 7 and fills the groove 11 together with the sealing strip 9. The gap between the fire cavity 7 and the door gap is filled, blocking external open flames and smoke from entering the bathroom; at the same time, an insulation board 6 is installed on the back of the expandable fireproof cotton block 5. The insulation board 6 is not easy to burn and can block the heat generated by the external fire source. A back-fire cavity 8 is arranged between the insulation board 6 and the aluminum plate part 4. The back-fire cavity 8 forms a buffer for the entry of the fire source, slows down the burning of the fire, and turns the bathroom into a favorable survival space, further prolonging the rescue time and ensuring life safety.

[0051] Preferably, the intumescent fireproof wool block 5 meets the EN45545HL3 grade.

[0052] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
