Description

Corner drainage system and windows having the same {CORNER DRAINAGE APPARATUS AND WINDOW INCLUDING SAME}

The present invention relates to a corner drainage device and a lift sliding type window including the same.

In the interior and exterior of the building, windows may be formed in the opening for the purpose of controlling access and lighting. Such windows can be divided into sliding, opening, or fixed types depending on the opening and closing method. In order to increase it, it can be classified as a system window that opens and closes by organically combining and operating the parts in the profile.

System windows are divided into Tilt & Turn (windows are lifted and folded), Parallel (windows are lifted and overlapped), and Lift & Sliding (windows are lifted and sliding) according to the opening and closing method. Among them, the lift sliding window includes a sliding or fixed window, and a window frame that is fixed to the inner and outer walls of the building surrounding the window. The opening formed by the window frame can be opened and closed using a sliding window sill. On the other hand, the lift sliding window raises and lowers the window through the runner in the profile through the lift-up and down operation of the handle, thereby locking and unlocking the window.

That is, in the locked state, the slidable slats are in the down state, and when the user rotates the handle to operate the runner, the slidable slats can slide to the up state.

The window sill used in the lift sliding window has a state of being pressed or not pressed on the inner surface located on the lower side of the inner surface of the window frame to improve airtightness. Due to this type of operation, the height of the steps or rails formed on the window frame may be lower than that of general Miseogi windows. This is because when the step of the window frame or the height of the rail is formed high, the height at which the window must be lifted for the lift operation becomes very large, which is very disadvantageous for maintaining the airtightness of the window.

Therefore, unlike the existing Miseogi windows, lift sliding windows are formed by the step of the window frame, so there may not be enough space for fresh water flowing in from the outside. and has a problem of overflowing to the interior side.

In order to solve this problem, a general lift sliding window can be formed in such a way as to prevent water from flowing into the indoor side as much as possible by providing a height difference between the fixed window formed on the outdoor side of the window frame and the sliding window portion formed on the relatively indoor side of the window frame. have. In addition, a method of processing drainage holes in various parts of the frame of the window frame may be used so that the introduced water can be sufficiently drained to the outdoor side.

However, as the height of the sash frame increases, the area of the sash frame becomes wider and the opening portion is reduced, which not only impairs the occupant's view and the aesthetics of the building, but also reduces the area of incidence of sunlight, and thermal insulation of the entire building It has a disadvantage in that it causes a decrease in performance and increases the consumption of heating and cooling energy.

The present invention has been devised to solve these problems, and a corner drainage device that smoothly drains the water from the outside to the outside to prevent overflow (water overflow) into the room, and a lift sliding method having the same to provide a window of

The upper end of the plate-shaped damper 46 may be rotatably coupled to the drain 43 through a hinge or the like on a portion of the front surface of the drain 43 positioned above the drain 482 . In the general case where the inflow water is not discharged to the outdoor side, there is a damper 46 provided to close the drain port 482, so that water located outdoors can be prevented from flowing back to the indoor side through the drain port 482, and pests, It can prevent foreign substances such as foreign substances and fine dust from entering.

10 is a view showing the path through which the inflow water exits through the corner drainage device 40 in a state in which the sliding area A1 and the fixed window pane area A2 of the window 1 according to an embodiment of the present invention are viewed from the top down. It is a view showing the drainage path (P). Specifically, the inflow water flowing from the outdoor side to the indoor side flows into the fresh water space 140 through the water collecting port 145, flows into the drain space 430 of the connected corner drainage device 40, and flows through the drain port 482. It can be drained outdoors. 11 is a longitudinal cross-sectional view showing a path P through which the inflow water exits through the corner drainage device 40 in the sliding area A1 of the window 1 according to an embodiment of the present invention. 12 is a longitudinal sectional view of the fixed window sill area A2 in which the corner drainage device 40 of the window 1 according to an embodiment of the present invention is not disposed.

At the rear end of the middle region of the profile cover lower material 141 based on the left and right directions, a water collecting port 145 that is opened in the vertical direction may be formed. 12 is a cross-sectional view of a portion in which the water catchment port 145 is formed among the fixed window-jaw area A2 of the window and door 1 . The sliding area A1 is a portion where the changjjak 30 is positioned when the window 1 is closed, and the fixed changjjak area A2 is a portion where the fixed window 20 is disposed.

The inflow water flowing over the profile from the outdoor side to the indoor side falls on the profile cover lower material 141, and the fresh water space 140 formed between the profile covers 141 and 144 and the inner profile 13 through the water collecting port 145. is introduced into The inflow water introduced into the fresh water space 140 flows toward the corner drainage device 40 disposed outside in the left-right direction. The inflow water may be delivered from the fresh water space 140 to the inlet space 420 formed between the inlet 42 and the inner profile 13 of the corner drainage device 40 . The inflow water flowing into the acquisition space 420 may reach the drainage space 430 by moving to the outdoor side through the inlet 481 opened along the front-rear direction. The inflow water reaching the drain space 430 may be guided to the drain port 482 by the inclined bottom surface of the drain part 43 , and may be drained outdoors while pushing the damper 46 . Since the influent water drained to the outdoor side does not have a section that becomes higher as it goes to the outdoor side, the influent does not flow back into the indoor side and can be drained to the outdoors through the intermediate profile 12 and the outer profile 11. Among these drainage paths P of the influent, the path of the influent coming in from the outside is indicated by a solid arrow, and the path of the influent entering the interior is indicated by a dotted line in FIGS. 10 and 11 . As can be seen, the water collecting port 145, the fresh water space 140, the drain space 430, and the drain port 482 are sequentially communicated to form an influent drainage path P, which is a path through which the influent is discharged from the indoor side to the outdoor side. can be

As such, by having a drainage structure that diverts the inflow water to the corner drainage device 40 and drains it, the lack of the fresh water space 140 formed between the inner profile 13 and the profile covers 141 and 144 is compensated for overflowing with water. can be prevented, and a situation in which water flows backward through the corner drainage device 40 from the outside to the inside can be prevented.

Therefore, since the lift sliding window of the present invention enables smooth drainage of influent water through the corner drainage device, it is not necessary to process multiple drainage holes in various parts of the window frame frame, thereby preventing the inflow of foreign substances such as dust or insects into the interior through the drainage holes can do. In addition, since the inflow water does not overflow to the indoor side even if the height of the window frame is not formed high, the area of the window frame is relatively reduced and the opening part is improved, which not only gives beauty to the building, but also gives the view of the occupants and the incident area of sunlight. It is possible to reduce heating and cooling energy consumption by increasing the efficiency of the overall insulation performance of the building.
