Abstract

A weep hole system having the function of a check valve is provided to improve the thermal insulating capacity, dew condensation resistance and sealing efficiency of windows and doors by cutting off the inflow of cold air current through a weep hole. A weep hole system having the function of a check valve comprises a body(10), a valve(20) and a cover(30). The body is formed in a cylindrical or square shape to make water and air move and provided with a holder to mount the valve, a cover mounting groove and an anchoring projection, the valve is manufactured with rubber or resin-based pad having low hardness and provided with a projection coupled to a mounting hole of the holder of the body, and the cover is provided with a projection attached to a mounting groove of the body to protect the valve and to improve in appearance and a drain hole(40) formed to discharge water.

           The present invention relates to a high-performance exterior windows and curtain walls, and in particular, to a high heat insulation, high airtight, anti-corrosion performance, and to a Weep hole system of an exterior window of an extended balcony and an exterior window of an energy-saving building.

         In the case of exterior windows or curtain walls, weep holes are installed on the outside of the isostatic space in order to discharge the water introduced into the interior through gaskets or joints. The thermal insulation is lowered and condensation is caused accordingly. Uncontrolled airflow can also reduce the airtightness of windows and windows, causing energy loss and thermal discomfort.

         In order to alleviate this problem, existing high-performance windows used baffle sponges attached to the inside of the weep holes to reduce the flow rate of water and airflow, thereby reducing side effects caused by cold air inflow.

          In addition, the cover of the existing drain hole (Weep Hole Cover) is used only as a design to decorate the appearance of the weep hole for the effect of building elevation, and takes the form for the inflow of water, but does not have the function to control the inflow of external cold air flow. It was a reality.

        Mitigating cold air movement of the weep hole using the baffle sponge described above not only lowers the flow velocity of the cold air but also lowers the flow rate of the discharged water at the same time, thereby significantly reducing the external discharge performance of rainwater that has flowed inwardly through the window joint or gasket gap. Had to take.

        In addition, in the super-energy-saving building, high insulation and high airtight windows are applied in principle, so it is necessary to control the small amount of airflow through the baffle sponge, and the bath, greenhouse, constant temperature and humidity room, clean room, and newborn room where performance is required by anti-corrosion. Condensation occurs in cold bridges caused by cold air flowing into the baffle sponge in the external windows.

       Therefore, the present invention is to solve the above problems, the outside of the cold air flows through the weep hole to smoothly discharge the rainwater flowing into the window frame joint and the gasket gap on the rainy day to prevent water from flowing through the weep hole to move Is to develop a deep hole system with a check valve function

       Ultimately, by attaching the present invention to the weep hole of the window, the water is discharged to the outside and the check valve is provided so that the cold air is not introduced, thereby blocking the inflow of the cold air through the weep hole to prevent insulation and anti-condensation, To improve

       In order to achieve the above object is composed of three parts, the body, the valve, the cover and the body 10 has a cylindrical or rectangular hollow form to flow water and air as shown in Figure 5 and the upper portion of the valve 20 There is a holder (11) to be mounted and the cover mounting groove 50 and the fixing projections 70 in the window is characterized in that the outside. The valve 20 is made of rubber or resin pads having a low hardness as shown in FIG. 4, and includes a protrusion 80 coupled to the holder 11 and the mounting hole 60 at the top of the body 10. The cover 30 is a drainage hole 40 for protecting the valve 20 and discharging water and a protrusion 90 attached to the mounting groove of the body 10 as a circular or rectangular component for the purpose of aesthetics as shown in FIG. 3. It is characterized by having).

     The assembled Weep Hole System as shown in FIG. 1 is inserted into the Weep Hole located at the lower end of the window by rotating 90 'left or right. Briefly explaining the principle of operation, the rainwater introduced through the window frame joint and the outer gasket first accumulates in the bite space inside the window frame, and when the head pressure occurs, the inner valve of the Weep Hole System opens to discharge the inflow rainwater to the outside. It's possible. On the contrary, if the rain stops and the inflow is lost and the wind blows, the cold air flows into the bite space and the inner gasket through the weep hole. The valve is then closed due to internal and external pressure differentials and the valve itself elastic to prevent the inflow of cold air.

     In addition, as shown in Figure 7, the sliding window is installed vertically the Weep Hole System to be installed on the inside, which makes the valve specific gravity smaller than water to operate as follows. If the water flows into the window frame gap, the valve inside the vertically installed Weep Hole System is opened by the buoyancy of the water, and when all the inflow water is released, the valve is closed by gravity to prevent the air from flowing out. In this case, the principle of operation of the Weep Hole System installed horizontally on the outside is the same.

      The present invention can be produced in a circular or rectangular shape according to the purpose of the design and can take the form of the release according to the needs of the design, the material of the valve, the body, the cover is also made of resin and rubber, etc. It can be made of wood, glass, porcelain, etc., and small spring or bimetal can be installed for smooth operation of the valve.

       As described above, the present invention is intended to improve the thermal insulation, anti-condensation, and airtight performance of high insulation airtight windows by blocking the inflow and outflow of cold air through the weep hole.

       This fundamentally solves the recent condensation of the exterior windows of the extended balcony to prevent the deterioration of the floorboard, which is the second damage caused by the condensation, the occurrence of mold, odors, and the like. Minimizing the energy consumption of buildings can be expected.

        In addition, the baffle sponge prevents the discharge of dust and debris from the bite space inside the window frame in the windows with existing baffle sponges, and minimizes the number of weep holes per unit area by the smooth flow of inflow water. have.

         In terms of durability, it is semi-permanent compared to the existing method of baffle sponge, and it is easy to maintain and replace parts in case of damage caused by uncertainty.
