Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of sliding doors, in particular to a screen door integrated lifting sliding door with staggered drainage holes. BACKGROUND

[0002] The screen door integrated lifting sliding door has been widely used in various scenes such as residences, commercial buildings, and office spaces, and has become one of the important choices for modern building exterior windows and entrance doors, because it combines the lighting of glass doors with the mosquito prevention function of screen doors, and has the advantages of high space utilization and convenient operation. However, in the long-term actual use process, the drainage system of the existing screen door integrated lifting sliding door still has many technical defects, which are difficult to adapt to the needs of different seasonal climate conditions (such as low temperature icing in winter, heavy rain and strong wind in summer) and complex use environment. The specific problems are as follows: 1. The drainage hole and drainage cavity design is unreasonable, and the risk of rainwater backflow is high The drainage structure design of the existing screen door integrated lifting sliding door is single, such as the direct communication between the water tank drainage hole and the track outer side drainage hole. When encountering heavy rain or strong wind weather in summer, outdoor rainwater is easy to directly backflow into the indoor along the drainage hole path driven by wind force, especially in coastal or rainy areas, the backflow problem is more prominent; 2. It is difficult to consider the winter drainage needs by setting foam or other porous drainage materials in the drainage hole to prevent backflow Some products set foam or other blocking pieces in the drainage hole to prevent backflow, but the foam is not easy to dry and melt ice due to its internal residual rainwater and porous structure, and the water in the foam will not be easy to drain after icing in winter; 3. Winter low temperature icing blocks the drainage hole, affecting the drainage function and the service life of the components In the winter low temperature environment, the bottom water tank and the surrounding of the drainage hole of the sliding door are easy to form thin ice due to the residual rainwater, and the existing structure lacks effective design for ice body processing: on the one hand, thin ice is easy to adhere to the inner wall of the water tank, and gradually thickens and blocks the drainage hole as the temperature decreases, which causes the rainwater to be unable to be normally drained, and even the stress generated by the expansion of the ice extrudes the water tank, track and other components, causing the water tank to crack and the track to deform; on the other hand, the ice body needs to be cleaned manually after being blocked, which is not only inconvenient to operate, but also easy to scratch the inner wall of the water tank or the edge of the drainage hole during the cleaning process, further shortening the service life of the components, and it is difficult to meet the user's use demand of "maintenance free"; 4. The rainwater collection efficiency is low, and the drainage rate is difficult to adapt to the heavy rain scene The existing door screen integrated lifting sliding door water tank is designed in a plane type, lacks a rainwater collection structure, and rainwater flows dispersedly in the water tank, so that sufficient water pressure cannot be formed to push the rainwater out quickly. Especially in heavy rain weather, the rainfall is far more than the drainage rate, which easily leads to the increase of the water depth in the water tank, increases the risk of backflow, and may cause the water to seep into the gap at the bottom of the door leaf, affect the smooth sliding of the door leaf, and even cause the hardware to rust and shorten the service life of the overall product.

[0003] 5. The anti-backflow component in the prior art cannot adjust the opening degree of the drainage hole The anti-backflow component in the existing drainage system cannot adaptively adjust the opening degree of the drainage hole according to seasonal temperature changes. In winter, a large opening degree is needed for ice and water drainage, and in summer, the opening degree of the drainage hole is reduced to prevent backflow and mosquitoes. The fixed opening degree design cannot meet the different needs in winter and summer, which limits the product adaptability.

[0004] In summary, the drainage system of the current door screen integrated lifting sliding door has obvious technical shortcomings in anti-backflow, anti-ice blockage, drainage efficiency and seasonal adaptability, and a new type of drainage structure that can adapt to the differences between winter and summer, and balance the functions of drainage efficiency and anti-backflow and anti-ice blockage is needed to solve the defects of the existing technology and improve the use performance and market competitiveness of the product.

DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings, which show several embodiments of the present application. However, the present application can be realized in different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can be a middle element, and when an element is referred to as being "connected to" another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] Please refer to the drawings Figures 1-15The application discloses a door screen integrated lifting sliding door with staggered drainage holes, which comprises an outer track 1 for slidingly arranging a glass door leaf, an inner track 2, an inner side of the inner track 2 being integrated with a screen door track 3 for slidingly arranging a screen door, and a multifunctional water tank 4 arranged on the outer track 1 and the inner track 2, the multifunctional water tank 4 being located below the outer glass door leaf and the inner glass door leaf, and the bottom of the multifunctional water tank 4 being provided with a water tank drainage hole 5. The outer track 1 is provided with a plurality of track drainage holes staggered with the water tank drainage hole 5 in a direction perpendicular to the glass door leaf, and the outer track 1 is provided with a plurality of track drainage cavities for connecting the water tank drainage hole 5 and the track drainage holes. The inner side of the multifunctional water tank 4 and the inner side of the water tank drainage hole 5 are provided with a sandwich layer 6, and the sandwich layer 6 is filled with a gas material. One side of the sandwich layer 6 close to the water tank drainage hole 5 is provided with a curved sandwich layer side wall 7, the top of the sandwich layer 6 is provided with a sandwich layer upper wall 8, and the outer side of the sandwich layer upper wall 8 is connected with the sandwich layer side wall 7. The sandwich layer side wall 7 and the opposite tank wall of the multifunctional water tank 4 form an ice falling tank 9, the ice falling tank 9 is located above the water tank drainage hole 5 and is communicated with the water tank drainage hole 5. The bottom of the multifunctional water tank 4 is provided with an opening degree adjusting air bag 10 communicated with the sandwich layer 6, the volume of the sandwich layer 6 is greater than the volume of the opening degree adjusting air bag 10, the opening degree adjusting air bag 10 has a plurality of air bag branches 11 arranged at intervals at the water tank drainage hole 5, and the air bag branches 11 adjust the size of the aperture between adjacent air bag branches 11 by expansion and contraction.

[0023] The technical scheme of the application is described below by taking the application scenarios in summer and winter as examples. In winter, the gas material in the sandwich layer 6 is reduced in volume due to the decrease of air temperature, so that a negative pressure is formed in the sandwich layer 6, the opening degree adjusting air bag 10 is shrunk due to the gas being sucked into the sandwich layer 6, and the aperture between adjacent air bag branches 11 is increased. At the same time, the sandwich layer side wall 7 on the outer side of the sandwich layer upper wall 8 is more easily bent and deformed than the tank wall of the multifunctional water tank 4 on the inner side of the sandwich layer upper wall 8, so that the outer side of the sandwich layer upper wall 8 is further bent downward due to the negative pressure in the sandwich layer 6, and the bending amplitude of the sandwich layer upper wall 8 is also increased with the decrease of air temperature. On the one hand, the thin ice formed on the sandwich layer upper wall 8 is peeled off and broken at the initial stage of formation due to the change of the bending amplitude of the sandwich layer upper wall 8, and the thin ice is further peeled off and broken due to the repeated bending of the sandwich layer upper wall 8 with the change of day and night temperature. On the other hand, the thin ice peeled off from the sandwich layer upper wall 8 is slid downward to the ice falling tank 9 due to the downward bending of the outer side of the sandwich layer upper wall 8, the height difference between the top of the sandwich layer upper wall 8 and the tank wall of the ice falling tank 9 further promotes the breaking of the peeled thin ice, and the adjacent air bag branches 11 are in a deflated state due to the low temperature, so that the broken ice is easily discharged through the water tank drainage hole 5, the drainage cavity and the track drainage hole.

[0024] In summer, the volume of the gas material in the interlayer 6 expands due to heat, at this time, due to the fact that the elasticity of the opening adjusting air bag 10 is greater than the elasticity of the interlayer upper wall 8 and the interlayer side wall 7, the expansion of the opening adjusting air bag 10 avoids the bending of the interlayer upper wall 8 upwards to affect the drainage of rainwater in the multifunctional water tank 4. At the same time, the apertures between the adjacent air bag branches 11 of the opening adjusting air bag 10 are reduced due to the expansion of the air bag branches 11, combined with the misalignment design of the water tank drain hole 5 and the track drain hole, thereby avoiding rainwater backflow in summer stormy weather.

[0025] In addition, the ice falling groove 9 plays a role in gathering rainwater, and by increasing the water depth to increase the water pressure, thereby facilitating the improvement of the drainage rate, especially in rainy weather, and the increase of the water depth is also beneficial to prevent backflow.

[0026] It should be noted that although the apertures between the adjacent air bag branches 11 are reduced in summer, compared with the existing way of preventing rainwater backflow by setting foam in the drain hole, the present application adopts the way of reducing the apertures between the adjacent air bag branches 11 combined with the water tank drain hole 5 and the track drain hole to prevent rainwater backflow, and the drainage resistance is obviously smaller.

[0027] In addition, in summer high-temperature weather, the reduction of the apertures between the adjacent air bag branches 11 is beneficial to block mosquitoes from entering the indoor through the water tank drain hole 5. When it rains, at this time, the mosquitoes are reduced, the temperature is reduced, and the multifunctional water tank 4 is cooled by rainwater, so that the apertures of the adjacent air bag branches 11 are increased compared with when it does not rain, thereby facilitating the drainage of rainwater, and compared with winter low-temperature weather, the air bag branches 11 are in a deflated state, at this time, the air bag branches 11 are still in an inflated state, thereby playing a role in preventing rainwater backflow.

[0028] It should be noted that the backflow prevention function of the present application is aimed at rainwater backflow caused by backflow wind, but not backflow caused by balcony waterlogging and ground waterlogging.

[0029] It should be noted that after the opening adjusting air bag 10 and the multifunctional water tank 4 are assembled, the gas material is filled into the interlayer 6 at room temperature such as 25°C, thereby ensuring that the opening adjusting air bag 10 can be inflated and deflated in summer and winter. The communication mode of the opening adjusting air bag 10 and the multifunctional water tank 4 can adopt a detachable pipeline structure connection, or the pipeline structures of the two can be directly bonded, and the specific selection is based on different properties, cost and other factors of the product.

[0030] And the two ends of the interlayer 6 are sealed with plastic film or elastic film to avoid affecting the deformation of the interlayer upper wall 8.

[0031] In summary, the present application has the following beneficial effects: 1、In winter, the gas material in the interlayer 6 can be used to cause the upper wall 8 of the interlayer to have different downward bending amplitudes according to temperature changes, so as to promote the peeling, breaking and sliding of thin ice on the upper wall 8 of the interlayer into the ice falling groove 9; 2、The ice falling groove 9 is designed to be connected to the water tank drain hole 5 and located above the water tank drain hole 5, so that the thin ice peeled off from the upper wall 8 of the interlayer cannot stay on the upper wall 8 of the interlayer, and the difference in height between the bottom groove wall of the ice falling groove 9 and the top of the upper wall 8 of the interlayer promotes the further breaking of the thin ice when it slides into the ice falling groove 9, which is beneficial to the thin ice passing through the water tank drain hole 5; 3、The ice falling groove 9 plays a role in gathering rainwater, and increasing the water pressure by increasing the water depth, thereby improving the drainage rate, especially in rainy weather, and the increase in water depth is also beneficial to preventing backflow; 4、The opening degree adjusting air bag 10 is arranged at the bottom of the multifunctional water tank 4, and the multiple air bag branches 11 below the water tank drain hole 5 are deflated in winter and inflated in summer, thereby reducing the opening degree of the water tank drain hole 5 and preventing backflow; 5、The opening degree adjusting air bag 10 can prevent the upper wall 8 of the interlayer from bending upward in summer, thereby avoiding affecting the drainage.

[0032] The track drainage cavity includes an internal drainage cavity 12 arranged inside the outer track 1, and an external drainage cavity 13 formed between the top of the outer track 1 and the bottom of the multifunctional water tank 4; The track drain hole includes a top drain hole 14 connected to the external drainage cavity 13 and the internal drainage cavity 12, and an outer side drain hole 15 arranged on the outer side of the outer track 1 and connected to the internal drainage cavity 12, the top drain hole 14 is connected to the water tank drain hole 5 through the external drainage cavity 13, and the top drain hole 14 and the outer side drain hole 15 are both arranged in a staggered manner with the water tank drain hole 5.

[0033] Through the design of double drainage cavities and triple staggered drain holes, the backflow prevention performance is further improved. In addition, it should be noted that although the water tank drain hole 5 and the top drain hole 14 are arranged in a staggered manner, they are partially overlapped in the vertical direction, rather than completely non-overlapping, which is beneficial to the drainage of rainwater and broken ice. In addition, the bottom cavity wall of the internal drainage cavity 12 is designed to be inclined downward, and the bottom hole wall of the outer side drain hole 15 is connected to the bottom cavity wall of the internal drainage cavity 12, thereby facilitating the drainage of broken ice and rainwater. At the same time, the design of the inclined bottom cavity wall of the internal drainage cavity 12 is also beneficial to preventing backflow.

[0034] Further optimization of the above embodiment is that a plurality of page plate shafts 16 are arranged in the water tank drain hole 5 and above the plurality of air bag branches 11, the plurality of page plate shafts 16 are arranged along the longitudinal direction of the multifunctional water tank 4, a pair of page plates 17 are arranged on the page plate shaft 16, and the air bag branch 11 is located between the corresponding pair of page plates 17 and close to the page plate shaft 16.

[0035] In winter, on the one hand, the rigid page plate shaft 16 is more likely to break the thin ice falling into the ice falling tank 9 than the elastic air bag branch 11. On the other hand, the two page plates 17 on the page plate shaft 16 respectively located on both sides of the air bag branch 11 can protect the air bag branch 11 from being scratched or even cut by the sharp edge of the broken ice.

[0036] And in summer, the page plates 17 on both sides of the air bag branch 11 are away from each other due to the expansion of the air bag branch 11, so as to improve the sensitivity of the two page plates 17 to the wind force of the backflowing wind. When the two page plates 17 are blown by the backflowing wind, they can further move away from each other, so as to further reduce the opening degree of the drain hole, thereby blocking the external rainwater and the rainwater in the multifunctional water tank 4 from flowing into the room.

[0037] It should be understood that when there is backflowing wind, rainwater cannot be smoothly discharged through the water tank drain hole 5. When the backflowing wind is small or there is no backflowing wind, the two page plates 17 are close to each other or fall on the expanded air bag branch 11, at this time, the water tank drain hole 5 has a large opening degree, which is beneficial to the smooth discharge of rainwater.

[0038] In addition, since the air bag branch 11 is close to the page plate shaft 16, i.e. the air bag branch 11 is close to the root of the page plate 17, the air bag branch 11 can control the page plate 17 to reciprocate with a large amplitude with a small expansion amplitude, i.e. it is beneficial to adjust the opening degree of the water tank drain hole 5 with fewer and narrower air bag branches 11. In the case of reducing the number of air bag branches 11, the number of page plate shafts 16 and page plates 17 is also reduced, and only the width of the page plate 17 in the radial direction of the page plate shaft 16 needs to be increased, which has the advantages of: 1. Reducing the number of air bag branches 11, page plate shafts 16 and page plates 17, thereby reducing the hardware cost; 2. Avoiding the adverse effects of too many air bag branches 11 on ice and water discharge of the water tank drain hole 5.

[0039] It should be noted that, since the air bag branch 11 is a flexible structure, and the air bag branch 11 is located below the leaf plate shaft 16, the air bag branch 11 is difficult to rotate the leaf plate 17 upward to the horizontal even if it is fully inflated, therefore, in order to realize that the adjacent two leaf plates 17 on the adjacent leaf plate shaft 16 can be in contact by the support of the corresponding air bag branch 11, and realize the safe closure of the sink drain hole 5, the width of the leaf plate 17 should be greater than 1 / 2 of the distance between the adjacent leaf plate shaft 16.

[0040] In addition, due to the actual situation due to the existence of various factors, the backflow wind reaching the sink drain hole 5 is usually not uniform and stable, and the leaf plate 17 will swing up and down with the change of wind power, therefore, the way of adjusting the sink drain hole 5 through the self-adaptive up and down swing of the leaf plate 17 not only will not affect the drainage of rainwater, and when the backflow wind is large, uneven and changes, the multiple leaf plates 17 can timely perceive the change of wind power and independently adjust the opening of the sink drain hole 5 in the corresponding area, so that the multiple leaf plates 17 can timely "grasp" the wind power "gap" of the backflow wind for drainage.

[0041] And in the prior art, the backflow is prevented by the porous foam, on the one hand, when the backflow wind is large, its backflow prevention effect is limited, on the other hand, after the backflow wind enters the pore structure inside the foam, it will diffuse under the action of resistance, so that the inside of the pore in the area of the foam which is not directly affected by the backflow wind will also form a positive pressure, which leads to the difficulty of the foam to timely "grasp" the wind power "gap" of the backflow wind for drainage.

[0042] It should be noted that, in order to avoid the leaf plate 17 on both sides of the leaf plate shaft 16 from turning to the same side of the air bag branch 11 when it is blown upward by a large wind force, and to avoid the leaf plate 17 from continuing to turn upward after turning 90° upward, which will weaken the backflow prevention effect, a limiting baffle 20 can be arranged on the inner wall of the accessory frame 19 above the leaf plate shaft 16, when the leaf plate 17 turns 90° upward, it will be in contact with the limiting baffle 20, thereby limiting the rotation amplitude of the leaf plate 17, so as to ensure that the function of the leaf plate 17 can be normally and effectively implemented.

[0043] In addition, the top of the sink drain hole 5 is provided with an embedded groove 18, the embedded groove 18 is embedded with an accessory frame 19, a plurality of leaf plate shafts 16 are rotatably arranged on the accessory frame 19, and a plurality of leaf plates 17 are arranged to form a detachable accessory, so as to facilitate the production, assembly and disassembly of the multifunctional sink 4. For example, when the multifunctional sink 4 or the accessory is damaged, only the multifunctional sink 4 or the accessory needs to be replaced, which is convenient to disassemble and assemble, and is conducive to reducing the maintenance cost in the later period.

[0044] In order to facilitate the bending of the outer side of the upper wall 8 of the interlayer 6 under the action of the negative pressure inside the interlayer 6, the bottom of the upper wall 8 of the interlayer 6 is provided with deformation guide grooves 21 in the longitudinal direction, and a plurality of deformation guide grooves 21 are arranged in the transverse direction of the upper wall 8 of the interlayer 6, and the depths of the plurality of deformation guide grooves 21 gradually increase in the direction towards the ice falling groove 9.

[0045] The upper wall 8 of the interlayer 6 at the position of the deformation guide grooves 21 is more easily bent due to the reduction in thickness, and the depths of the plurality of deformation guide grooves 21 gradually increase in the direction towards the outer side, which can increase the bending amplitude of the upper wall 8 of the interlayer 6 under the action of the negative pressure inside the interlayer 6, facilitate drainage and peeling of thin ice, and guide the outer side of the upper wall 8 of the interlayer 6 to bend downwards by a larger amplitude, avoiding the downward depression of the unsupported part between the outer side and the inner side of the upper wall 8 of the interlayer 6, which affects the drainage of rainwater and thin ice.

[0046] Correspondingly, the thickness of the interlayer side wall 7 is smaller than the thickness of the upper wall 8 of the interlayer 6, so that the interlayer side wall 7 is more easily deformed than the upper wall 8 of the interlayer 6, facilitating the downward bending of the outer side of the upper wall 8 of the interlayer 6.

[0047] The shape of the interlayer side wall 7 can be various, such as triangular, arched, "M" shaped, "Z" shaped, and preferably, the interlayer side wall 7 can deform towards the inside of the interlayer 6 to avoid negative effects on drainage and ice removal.

[0048] Further optimization of the above embodiment is that the top of the upper wall 8 of the interlayer 6 is provided with a fissure protrusion 22 in the width direction, and a plurality of fissure protrusions 22 are arranged at intervals along the length direction of the upper wall 8 of the interlayer 6, the fissure protrusion 22 is provided with a plurality of slits 2201 in the width direction of the upper wall 8 of the interlayer 6, and a ridge-shaped protrusion 2202 is formed between adjacent slits 2201, the adjacent ridge-shaped protrusions 2202 limit the upward bending of the upper wall 8 of the interlayer 6 by mutual interference, avoiding the upward bending of the upper wall 8 of the interlayer 6 for gas supply under the condition of high pressure for a long time, which affects the drainage performance of the multifunctional sink 4.

[0049] The ridge-shaped protrusion 2202 is provided with two metal strips 23 made of different metal materials at intervals, such as copper strips and aluminum strips, copper strips and iron strips, iron strips and aluminum strips, and the like, and the two metal strips 23 are preferably arranged horizontally and close to the upper wall 8 of the interlayer 6, the two metal strips 23 are exposed when the upper wall 8 of the interlayer 6 bends downwards, and the two metal strips 23 generate heat by electrochemical reaction with rainwater as electrolyte.

[0050] It should be noted that since rainwater is a weak electrolyte, the consumption of metal strip 23 is relatively slow, although the heat production is small, but the main purpose of using two metal strips 23 electrochemical reaction heat production is not to melt ice, the main purpose is to make the thin ice formed on the upper wall 8 of the interlayer has different thickness, thereby facilitating the breaking of thin ice, two is the interlayer upper wall 8 has a crack ridge 22 area and no crack ridge 22 area of the ice time is inconsistent, using slightly later crack ridge 22 area of ice as lubrication, thereby facilitating the peeling and sliding of thin ice.
