Description

Technical Field

[0001] The utility model relates to a door and window, in particular to a window frame and an inward-opening window. Background Art

[0002] Doors and windows are categorized as outward-opening, inward-opening, and sliding windows, depending on how the sash opens. These windows employ different sealing structures to enhance their airtightness and waterproofing. For inward-opening windows, existing window frames typically feature drainage holes on the exterior side. When rainwater flows through the screen and onto the top of the window frame, it drains out through the holes to the outside. However, when the amount of rain is high, it accumulates on the frame, and the drainage holes on the exterior side of the frame are unable to drain the water quickly enough, causing rainwater to seep into the room. Therefore, a more waterproof inward-opening window frame is urgently needed. Utility Model Content

[0003] The purpose of the present utility model is to provide a window frame and an inward-opening window to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is:

[0005] A window frame comprises: a lower frame, an outer baffle extending upward is provided on the outdoor side of the lower frame, a drainage groove is provided on the lower side of the lower frame below the outer baffle, a water storage tank is provided on the middle top side of the lower frame, a first drainage hole connected to the drainage groove and the water storage tank is provided on the lower frame, and an inner concave corner is provided on the top of the indoor side of the lower frame.

[0006] This technical solution has at least the following beneficial effects: the lower frame is installed at the bottom side of the wall hole, the side close to the outside of the wall hole is the outdoor side, and the side close to the inside of the wall hole is the indoor side. When the external glass window sash and the screen window sash are closed, the bottom side of the screen window sash abuts the indoor side of the outer baffle, and the outer baffle is used to limit the stroke of the screen window sash, while the bottom side of the glass window sash abuts the inner concave angle. The inner concave angle can be used to limit the stroke of the glass window sash and form a seal for the glass window sash at the inner concave angle position of the lower frame. When rainwater flows through the screen into the top side of the lower frame, the water storage tank can be used to transfer and buffer the rainwater to prevent excessive rainwater from flowing directly into the room. The rainwater in the water storage tank can enter the drainage tank through the first drainage hole and be discharged from the drainage tank to the outside. In this way, by temporarily storing and buffering the rainwater, the problem of excessive rainwater flowing back into the room can be effectively prevented, effectively improving the waterproofness of the inward-opening window and the overall usage experience.

[0007] As a further improvement of the above technical solution, the lower frame includes a bottom frame, an outer frame and a conversion frame. The top side of the bottom frame is connected to a connecting baffle extending upward, and the bottom of the connecting baffle is provided with the first drainage hole. The outer frame is connected to the outdoor side of the connecting baffle, and the outer baffle is formed on the outdoor side of the outer frame. The drainage groove is formed between the bottom side of the outer frame, the outdoor side of the connecting baffle and the top side of the lower frame. The conversion frame is connected to the top side of the bottom frame, and the conversion frame is spaced apart on the indoor side of the connecting baffle. The water storage tank is formed between the conversion frame and the connecting baffle. The bottom frame is used to be connected to the wall hole. The bottom frame can be used as a universal frame and can be used on frames other than the lower frame. In the lower frame, the outer frame is connected to the connecting baffle. The outer baffle formed on the outer frame can be used to block and limit the screen fan. The conversion frame is installed on the top side of the lower frame close to the indoor position for blocking and limiting the window sash. A drainage groove is formed between the bottom side of the outer frame, the outdoor side of the outer baffle and the top side of the bottom frame. A water storage tank is formed between the indoor side of the outer baffle, the top side of the bottom frame and the outdoor side of the conversion frame. The water storage tank and the drainage tank are connected to each other through the first drainage hole at the bottom of the connecting baffle. In this way, a water storage tank is formed by using the connecting baffle on the bottom frame and the connected and installed conversion frame to transfer and buffer rainwater before discharging it outward.

[0008] As a further improvement to the above technical solution, a diversion slope is provided on the indoor side of the outer frame, extending obliquely toward the interior of the room to the top side of the connecting baffle. During use, the gap between the screen frame and the glass frame is aligned with the diversion slope. When rainwater passes through the screen frame, it flows from the gap between the screen frame and the glass frame onto the diversion slope. Guided by the diversion slope, the rainwater is better collected into the water storage tank, thereby better unifying the flow of rainwater on the lower frame and improving rainwater drainage efficiency.

[0009] As a further improvement to the above technical solution, a second drainage hole is provided on the diverter slope near the connecting baffle, and a third drainage hole is provided on the bottom side of the outer frame directly opposite the second drainage hole. Rainwater flows from the diverter slope to the connecting baffle through the second drainage hole. At this point, some rainwater flows directly into the gutter after passing through the second and third drainage holes, and is discharged outdoors from the gutter. This improves rainwater drainage efficiency and reduces the pressure on the water storage tank to buffer rainwater transfer.

[0010] As a further improvement to the above technical solution, a fourth drainage hole is provided in the middle of the top side of the outer frame, and a fifth drainage hole is provided on the bottom side of the outer frame, directly opposite the fourth drainage hole. If excessive rainwater seeps in through the screen frame, some of the rainwater will spread to the top side of the outer frame. At this time, it can flow through the fourth and fifth drainage holes into the drainage trough, and then be discharged outdoors from the drainage trough, thereby reducing the accumulation of rainwater on the outer frame.

[0011] As a further improvement to the above technical solution, a sealing strip is provided between the bottom of the outdoor side of the conversion frame and the bottom frame. The sealing strip can improve the sealing between the outdoor side of the conversion frame and the bottom frame, making it difficult for rainwater in the water storage tank to seep into the area between the conversion frame and the bottom frame, thereby improving the reliability of the overall structure.

[0012] As a further improvement to the above technical solution, a positioning step is provided on the indoor bottom of the conversion frame, and the indoor top of the bottom frame fits into the positioning step. When the conversion frame is installed, the indoor top of the lower frame and the positioning step on the indoor bottom of the conversion frame cooperate with each other, allowing for quick connection and positioning between the two. This also reduces exposure at the connection point, improving the appearance and sealing of the connection.

[0013] As a further improvement of the above technical solution, a heat insulating strip is provided inside the conversion frame, which can reduce the direct conduction of indoor and outdoor heat through the conversion frame, thereby improving the heat preservation performance of the conversion frame.

[0014] As a further improvement to the above technical solution, the top side of the thermal insulation strip is provided with a main slot, and the conversion frame is provided with sub-slots on either side of the thermal insulation strip. During use, the external strip can be snapped into the main slot and the sub-slot, thereby securing it to the conversion frame, forming a partition and sealing structure between the conversion frame and the glass sash frame. Due to the multiple connection points between the strip and the conversion frame, the stability of the strip connection is greatly improved, and the sealing between the strip and the conversion frame is enhanced.

[0015] An inward-opening window comprises the above-mentioned window frame.

[0016] This technical solution has at least the following beneficial effects: since the inward-opening window has the above-mentioned window frame, when in use, when rainwater flows through the screen into the top side of the lower frame, the water storage tank can be used to transfer and buffer the rainwater to prevent excessive rainwater from flowing directly into the room. The rainwater in the water storage tank can enter the drainage trough through the first drainage hole and be discharged to the outside from the drainage trough. In this way, by temporarily storing and buffering the rainwater, the problem of excessive rainwater flowing back into the room can be effectively prevented, and the waterproofness of the inward-opening window and the overall user experience can be effectively improved.

[0025] Reference Figure 1 A window frame includes a lower frame, an outer baffle 210 extending upward is provided on the outdoor side of the lower frame, a drainage groove 110 is provided on the lower frame below the outer baffle 210, a water storage tank 120 is provided on the middle top side of the lower frame, a first drainage hole connected to the drainage groove 110 and the water storage tank 120 is provided on the lower frame, and an inner concave corner 130 is provided on the indoor top of the lower frame. In actual application, the window frame also includes an upper frame and a side frame, and the upper frame and the lower frame are respectively installed on the upper and lower sides of the wall hole along the up and down direction, and the side frames are respectively connected between the left and right ends of the upper frame and the left and right ends of the lower frame.

[0026] As can be seen from the above, the lower frame is installed at the bottom side of the wall hole, the side close to the outside of the wall hole is the outdoor side, and the side close to the inside of the wall hole is the indoor side. When the external glass window sash and the screen window sash are closed, the bottom side of the screen window sash abuts against the indoor side of the outer baffle 210, and the outer baffle 210 is used to limit the travel of the screen window sash, and the bottom side of the glass window sash abuts against the inner concave angle 130. The inner concave angle 130 can be used to limit the travel of the glass window sash and control the position of the glass window sash in the lower frame. The concave corner 130 forms a seal. When rainwater flows through the screen window into the top side of the lower frame, the water storage tank 120 can be used to transfer and buffer the rainwater to prevent excessive rainwater from flowing directly into the room. The rainwater in the water storage tank 120 can enter the drainage tank 110 through the first drainage hole and be discharged to the outside from the drainage tank 110. In this way, by temporarily storing and buffering the rainwater, the problem of excessive rainwater flowing back into the room can be effectively prevented, thereby effectively improving the waterproofness of the inward-opening window and the overall user experience.

[0027] The lower frame can be an integrally formed structure, and in order to improve the versatility of the profile and reduce production costs, the lower frame can be formed by splicing multiple structures. In this embodiment, the lower frame includes a bottom frame 100, an outer frame 200 and a conversion frame 300. The top side of the bottom frame 100 is connected to a connecting baffle 140 extending upward, and the bottom of the connecting baffle 140 is provided with the first drainage hole. The outer frame 200 is connected to the outdoor side of the connecting baffle 140, and the outer baffle 210 is formed on the outdoor side of the outer frame 200. The bottom side of the outer frame 200, The drainage groove 110 is formed between the outdoor side of the connecting baffle 140 and the top side of the lower frame. The conversion frame 300 is connected to the top side of the bottom frame 100. The conversion frame 300 is spaced apart on the indoor side of the connecting baffle 140. The water storage tank 120 is formed between the conversion frame 300 and the connecting baffle 140. In actual application, screws can be inserted into the connecting baffle 140 and connected to the outer frame 200 to connect and fix the two to each other, and screws can be inserted into the conversion frame 300 and connected to the bottom frame 100 to connect and fix the two. The bottom frame 100 is used to connect to the wall hole. The bottom frame 100 can be used as a universal frame and can be used on frames other than the lower frame. In the lower frame, the outer frame 200 is connected to the connecting baffle 140. The outer baffle 210 formed on the outer frame 200 can be used to block and limit the screen fan. The conversion frame 300 is installed at a position close to the indoor position on the top side of the lower frame to block and limit the window sash. The bottom side of the outer frame 200, the outdoor side of the outer baffle 210 and the bottom frame are connected. A drainage trough 110 is formed between the top sides of the body 100, and a water storage tank 120 is formed between the indoor side of the outer baffle 210, the top side of the bottom frame 100 and the outdoor side of the conversion frame 300. The water storage tank 120 and the drainage trough 110 are connected to each other through the first drainage hole at the bottom of the connecting baffle 140. In this way, the water storage tank 120 is formed by utilizing the connecting baffle 140 on the bottom frame 100 and the connected and installed conversion frame 300, which can transfer and buffer rainwater and then discharge it outward.

[0028] In the above embodiment, the water storage tank 120 may be positioned directly opposite the gap between the screen window frame and the glass sash frame. In this case, rainwater flows directly through the gap into the water storage tank 120, which may easily cause rainwater to splash on the lower frame. To reduce this, a guide structure may be provided at the location where the rainwater falls. Specifically, a diversion slope 220 is provided on the indoor side of the outer frame 200. The diversion slope 220 extends obliquely in a direction closer to the indoor environment to the top side of the connecting baffle 140. During use, the gap between the screen window frame and the glass sash frame is positioned directly opposite the diversion slope 220. When rainwater passes through the screen window frame, it flows from the gap between the screen window frame and the glass sash frame to the diversion slope 220. The guidance of the diversion slope 220 can better collect the rainwater into the water storage tank 120, thereby better unifying the flow direction of rainwater on the lower frame and improving the efficiency of rainwater discharge.

[0029] To improve drainage efficiency, in this embodiment, a second drainage hole is provided on the inclined diversion surface 220 near the connecting baffle 140, and a third drainage hole is provided on the bottom side of the outer frame 200, directly opposite the second drainage hole. Rainwater flows from the inclined diversion surface 220 to the connecting baffle 140 through the second drainage hole. At this point, some rainwater flows directly into the gutter 110 after passing through the second and third drainage holes, and is discharged outdoors from the gutter 110. This improves drainage efficiency and reduces the pressure on the water storage tank 120 to buffer the rainwater during transit.

[0030] In actual use, rainwater that penetrates the screen window sash frame tends to spread along the sidewalls of the screen window sash frame to its bottom side and drip onto the outer frame 200. To drain the rainwater that accumulates on the outer frame 200, in this embodiment, a fourth drainage hole is provided in the middle of the top side of the outer frame 200, and a fifth drainage hole is provided on the bottom side of the outer frame 200, directly opposite the fourth drainage hole. When the amount of rainwater that penetrates the screen window sash frame is too large, some of the rainwater will spread to the top side of the outer frame 200. At this time, the rainwater can flow into the drainage groove 110 through the fourth and fifth drainage holes, and then be discharged to the outside through the drainage groove 110, thereby reducing the accumulation of rainwater on the outer frame 200.

[0031] Because rainwater tends to accumulate between the outer baffle 210 and the conversion frame 300, in order to better reduce rainwater seepage from the connection between the conversion frame 300 and the bottom frame 100, in this embodiment, a sealing strip is provided between the bottom of the outdoor side of the conversion frame 300 and the bottom frame 100. The sealing strip improves the sealing performance of the connection between the outdoor side of the conversion frame 300 and the bottom frame 100, making it difficult for rainwater in the water storage tank 120 to seep into the area between the conversion frame 300 and the bottom frame 100, thereby improving the reliability of the overall structure.

[0032] When the conversion frame 300 is connected to the bottom frame 100, the indoor surface of the conversion frame 300 can be flush with the indoor surface of the bottom frame 100. In order to facilitate mutual positioning when the conversion frame 300 is connected to the bottom frame 100, in this embodiment, a positioning step 310 is provided at the bottom indoor side of the conversion frame 300, and the top indoor side of the bottom frame 100 is fitted and connected within the positioning step 310. When installing the conversion frame 300, the top indoor side of the lower frame and the positioning step 310 at the bottom indoor side of the conversion frame 300 cooperate with each other, thereby achieving quick connection and positioning between the two, reducing the exposure of the connection position between the two, and improving the appearance and sealing of the connection position.

[0033] To improve the thermal insulation performance of the lower frame, in this embodiment, thermal insulation strips 320 are provided within the conversion frame 300. In actual use, thermal insulation strips are also provided within the bottom frame 100 to improve the thermal insulation performance of the bottom frame 100 itself. The thermal insulation strips 320 can reduce the direct conduction of heat between indoor and outdoor spaces through the conversion frame 300, thereby improving the thermal insulation performance of the conversion frame 300.

[0034] In some embodiments, a main slot 330 is provided on the top side of the thermal insulation strip 320, and sub-slots 340 are provided on both sides of the thermal insulation strip 320 of the conversion frame 300. In actual application, the top side of the thermal insulation strip 320 may be formed with two upwardly protruding main hooks, with the main slot 330 formed between the two main hooks. Sub-hooks are spaced apart on the conversion frame 300 at the positions of the two main hooks, and sub-slots 340 are formed between the two opposing main hooks. During use, the external rubber strip can be clipped into the main slot 330 and the sub-slot 340, thereby fixing it to the conversion frame 300, forming a partition sealing structure between the conversion frame 300 and the glass sash frame. Because there are multiple connection points between the rubber strip and the conversion frame 300, the stability of the rubber strip connection is greatly improved, and the sealing between the rubber strip and the conversion frame 300 is enhanced.

[0035] An inward opening window comprises the above-mentioned window frame. In actual application, a screen fan and a window sash are installed in the window frame. The screen fan and the window sash are respectively rotatably connected to one side of the window frame, that is, the side frame of the window frame.

[0036] In this inward-opening window, since the inward-opening window has the above-mentioned window frame, when in use, when rainwater flows into the top side of the lower frame through the screen, the water storage tank 120 can be used to transfer and buffer the rainwater to prevent excessive rainwater from flowing directly into the room. The rainwater in the water storage tank 120 can enter the drainage tank 110 through the first drainage hole and be discharged to the outside from the drainage tank 110. In this way, by temporarily storing and buffering the rainwater, the problem of excessive rainwater flowing back into the room can be effectively prevented, thereby effectively improving the waterproofness of the inward-opening window and the overall user experience.

[0037] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
