Description

Technical Field

[0001] The invention relates to the technical field of building doors and windows, and in particular to a hidden drainage piece for doors and windows. Background Art

[0002] Doors and windows are very important components of buildings, and the impact of their performance on the indoor environment is self-evident. In order to avoid water accumulation in the door and window structure when it rains, a drainage mechanism must be set on the doors and windows. There are two main existing drainage methods. The first is open drainage. Drainage holes are opened on the cantilever of the door and window frame or connected to the outside to achieve the purpose of drainage. In order to prevent rainwater from backflowing in strong convection weather and prevent mosquitoes, a cover is generally added to the drainage hole, and a movable valve is added inside the cover. This method has the following disadvantages: 1. The horizontal pressure difference of rainwater discharge is small. In strong convection weather, there will be a problem of untimely drainage and overflow into the room when there is a lot of rainwater and water accumulation. 2. Due to the imperfect structural design of the valve itself, some rainwater will still backflow under wind and rain, and some will produce a whistling sound. 3. After the valve passes through the water, it sometimes adheres to the door and window frame, resulting in poor drainage. 4. The cover is exposed and protruding, and it is often lost before the decoration starts, and it seriously affects the outdoor decoration effect. The second type is groove drainage, which divides the cavity on the outdoor side of the door and window frame into two parts, the upper part of the cavity is open, and the drainage hole is set on the upper wall of the outdoor side of the door and window frame. Rainwater first flows down into the open cavity and is directly discharged to the outside. Compared with open drainage, groove drainage greatly improves the aesthetics, but it also has the following disadvantages: 1. The outdoor side of the door and window frame is divided into two parts, the upper part is open, and the corner code or connector cannot be placed, so the connection strength will be reduced. 2. Because of the groove, the bottom will be exposed if the spraying is not in place, which will affect the service life. 3. It is easier to hide dirt and inconvenient to clean. 4. There are grooved and non-grooved horizontal and vertical aluminum materials. They are not the same material, and the connection position is generally not too flat. 5. If it is not handled properly, it will produce a whistling sound. 6. Different horizontal and vertical materials increase inventory pressure. Therefore, the market needs a solution with beautiful appearance, less preparation, easy processing, and smooth drainage. Summary of the invention

[0008] Preferably, the drainage bucket is in the shape of a funnel that is wide at the top and narrow at the bottom and is roughly in the shape of an inverted "L" as a whole, and a supporting rib is provided in the middle of the lower part of the drainage bucket.

[0009] Preferably, the drainage bucket consists of a wide-mouth section, a closed-mouth section and a narrow-mouth section, wherein the closed-mouth section is formed by the lower end of one side of the wide-mouth section being inclined and closed toward the opposite side, the narrow-mouth section is adjacent to the closed-mouth section and extends downward and is offset to one side of the wide-mouth section, and the narrow-mouth section is located between the cantilever of the door and window frame and the glass.

[0010] Preferably, the lower end of the narrow mouth section forms an inclined surface structure with a certain angle.

[0011] Preferably, through-going air pressure balance holes extend outward from both sides of the lower end of the drainage bucket.

[0012] Preferably, a first mounting portion is provided on the side of the lower end of the narrow mouth section facing the cantilever of the door and window frame, and the first mounting portion is snap-connected with the rubber strip groove on the horizontal door and window frame; a second mounting portion is provided on the side of the wide mouth section away from the cantilever of the door and window frame, and the second mounting portion is snap-connected with the water-blocking retaining edge on the door and window frame.

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Explanation of the reference numerals of the components: drain pipe 1, drain bucket 2, upper horizontal wall 3, lower horizontal wall 4, upper drain hole 5, lower drain hole 6, drip eaves 7, guide ribs 8, convex limit blocks 9, positioning dividing line 10, insect-proof grille 11, insect-proof net 12, wide-mouth section 13, closing section 14, narrow-mouth section 15, door and window frame cantilever 16, first mounting part 17, rubber strip groove 18, second mounting part 19, water-blocking rib 20, inclined structure 21, supporting ribs 22, air pressure balance hole 23, door and window frame 24, guide angle 25, glass 26, contact surface S.

[0034] like Figure 1As shown in FIG2 , the present embodiment provides a quick-install hidden drainage component for doors and windows with a secondary drainage function, which is vertically installed on a horizontal door and window frame, and includes a drainage pipe 1 and a drainage bucket 2. Drainage holes are provided on the upper and lower horizontal walls 3 and 4 of the door and window frame 24. The drainage pipe 1 is vertically penetrated and installed in the drainage holes. The drainage holes are an upper drainage hole 5 and a lower drainage hole 6 that are completely symmetrical. Therefore, there is no need to distinguish the directions. During processing, positioning devices can be set at both ends of the processing equipment to avoid the process of measuring, marking and locating when processing the drainage holes, which can significantly improve the production efficiency. The outer tube wall of the drain pipe 1 extends downward to form a drip eave 7, and the drain bucket 2 is arranged directly below the drain pipe 1. The drain bucket 2 is clamped on the door and window frame 24 and the upper end of the drain bucket 2 can completely surround the opening of the lower drain hole 6. A gap of 0.5-15mm is formed between the drip eave 7 and the periphery of the lower drain hole 6. If the rain is too heavy, the rainwater may leak from the upper drain hole 5. The leaked rainwater can flow down along the drip eave 7 of the outer wall of the drain pipe 1 into the drain bucket 2 without accumulating between the upper horizontal wall 3 and the lower horizontal wall 4 of the door and window frame. At the same time, since the upper end of the drain bucket 2 can completely surround the opening of the lower drain hole 6, the rainwater flowing down along the drip eave 7 can flow into the drain bucket 2 through the gap without flowing into other parts of the door and window frame 24, thereby achieving a good seal without sealing and rubber pads, thereby forming a second waterproof line for the drainage component.

[0035] like Figure 2 and 9 As shown, the drain pipe 1 adopts a variable diameter structure with a larger upper portion and a smaller lower portion and is pressed into the drain hole from top to bottom. The upper end of the drain pipe 1 has a contact surface S that is interference fit with the drain hole, and there are 6 guide ribs 8 below the contact surface S to facilitate overall guidance of the drain pipe 1 during installation to prevent the drain pipe 1 from tilting when inserted into the drain hole, so that it can be smoothly pressed to the predetermined position.

[0036] like Fig.10 As shown, two guide angles 25 may also be provided below the contact surface S to achieve overall guidance.

[0037] like Figure 2, 3, 8, 9, and 11, the upper wall of the drain pipe 1 is provided with four convex stop blocks 9 protruding outward, and the convex stop blocks 9 abut against the upper transverse wall 3. When the drain pipe 1 is pressed into the drain hole, the convex stop blocks 9 abut against the upper transverse wall 3, thereby limiting the drain pipe 1 and preventing it from falling out of the drain hole. The upper wall of the drain pipe 1 is slightly concave in the upper transverse wall 3 of the door and window frame or flush with the upper transverse wall 3 of the door and window frame, so that water can be easily drained from the drain pipe 1 without accumulating on the transverse wall 3 of the door and window. In addition, the drain pipe 1 is made of soft material and is squeezed and sealed with the upper drain hole 5, without the need to apply sealing glue in advance, thereby forming the first waterproof line to prevent rainwater from pouring into the door and window frame. In addition, the drain pipe 1 is provided with one or more positioning dividing lines 10 on the pipe wall below the guide rib 8 or the guide angle 25, and can be shortened along the positioning dividing line 10 according to actual application to adapt to door and window frames of different thicknesses. A plurality of insect-proof grilles 11 are arranged at the upper end of the drain pipe 1, and the drain pipe 1 is a hollow tubular structure with a circular, flat or other arbitrary cross-section. The drain pipe 1 is a bilaterally symmetrical structure for easy insertion. A separate insect-proof net 12 can also be provided between the upper side of the drain bucket 2 and the lower side of the drain pipe 1.

[0038] like Figure 5-8 As shown, the drainage bucket 2 is funnel-shaped, which is wide at the top and narrow at the bottom and is roughly in an inverted "L" shape as a whole. It consists of a wide-mouth section 13, a closed section 14 and a narrow-mouth section 15, wherein the closed section 14 is formed by the lower end of one side of the wide-mouth section 13 being inclined and closed toward the opposite side, and the narrow-mouth section 15 is adjacent to the closed section 14 and extends downward and is offset to one side of the wide-mouth section 13, and the narrow-mouth section 15 is located between the door and window frame cantilever 16 and the glass 26, and the lower part of the wide-mouth section 13 is closed toward one side to form an escape space, and the lower end of the narrow-mouth section 15 forms a slope structure 21 with a certain angle, so that the setting of the drainage bucket 2 will not affect the opening and closing of window sashes and door sashes, thereby expanding the scope of use of the drainage component. At least one first mounting portion 17 is provided on the side of the lower end of the narrow mouth section 15 which is installed toward the cantilever 16 of the door and window frame. The first mounting portion 17 is snap-fitted with the rubber strip groove 18 on the transverse frame, and the first mounting portion may be a snap-fitting structure; a second mounting portion 19 is provided on the side of the wide mouth section 13 which is away from the cantilever 16 of the door and window frame. The second mounting portion 19 is snap-fitted with the water-blocking retaining edge 20 on the door and window frame 24, and the second mounting portion 19 may be a transverse linear protrusion, which may make the wide mouth section 13 and the water-blocking retaining edge 20 fit more tightly, and the drainage bucket 2 is snap-fitted and fixed to the door and window frame, without nails or glue, and can be quickly installed with one hand.

[0039] A support rib 22 is provided in the middle of the lower drainage part of the drainage bucket 2 to prevent the drainage bucket 2 from being flattened and deformed. Air pressure balance holes 23 extending from both sides of the lower end of the drainage bucket 2 can achieve air pressure balance, thereby achieving better drainage performance.

[0040] Independent closed cavities are formed at both ends of the door and window frames by injecting glue. In strong convective weather, if too much water seeps into the cavity of the door and window frames, since both ends of the door and window frames are blocked, the rainwater can flow into the drainage bucket from the above-mentioned gap instead of flowing into other parts of the door and window frames.

[0041] In addition, the number of drainage pieces in the present invention can be determined according to different sizes, and the material of the drainage pipe can also be selected to be hard material.

[0042] When rainwater flows into the drain pipe, it falls into the drainage bucket below and is directly discharged. If the amount of rainwater is large and seeps in from around the drain pipe, the seeped rainwater will flow down along the drip eaves and flow into the drainage bucket through the gap between the drip eaves and the periphery of the lower drainage hole to achieve secondary drainage. At this time, no matter whether a soft drain pipe or a hard drain pipe is used, there will be no leakage. Because the floor drain type vertical downward drainage is adopted, the drop is large, and because it is set inside the door and window frame, it is less affected by the headwind, so the drainage is smoother.

[0043] The above description is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention. The present invention may also have other various embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the claims of the present invention.
