Description

Technical Field

[0001] The utility model relates to the technical field of door and window insulation structures, in particular to a structure and a door and window system for increasing the temperature of door and window glass in winter. Background Art

[0002] The statements in this section merely provide background technology related to the present invention and do not necessarily constitute prior art.

[0003] The thermal insulation performance of the external envelope structure has a great influence on the indoor temperature of the central heating area. Among the external envelope structures, the thermal insulation performance of doors and windows is particularly important. According to relevant data, in residential buildings, heat loss through doors and windows accounts for about 50%.

[0004] In order to improve the thermal insulation performance of the enclosing structure, the glass structure of doors and windows in most cold areas has been improved from single-layer glass to double-layer glass or hollow glass, and even triple-layer glass door and window structure designs have appeared in some areas. This has a certain effect on reducing the thermal conductivity of doors and windows, improving the thermal insulation performance of the enclosing structure and even preventing noise.

[0005] However, the inventors found that although this type of door and window design has a certain effect on heat conduction, it still has the following problems: (1) It cannot change the heat radiation loss caused by indoor people passing through the lower temperature glass; (2) Since the glass temperature is relatively low, the air near the indoor glass is affected by the low temperature of the glass, causing the air temperature to continue to decrease and sink, thereby forming cold wind. Conventional methods cannot solve the problem of human thermal comfort near doors and windows. Utility Model Content

[0006] In order to address the deficiencies in the prior art, the utility model provides a structure and a door and window system for increasing the temperature of door and window glass in winter. Without adding additional energy, the utility model can utilize the fluid characteristics to effectively increase the temperature of door and window glass, reduce the heat radiation of the human body to the glass, and at the same time reduce the feeling of cold wind caused by the sinking of air near the doors and windows, thereby improving the thermal comfort of indoor personnel and effectively improving the overall quality of the indoor thermal environment.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] In a first aspect, the utility model provides a structure for increasing the temperature of door and window glass in winter.

[0010] A breathing valve is arranged on one side of the second through hole close to the external environment, a wind cap is arranged outside the breathing valve, and both the breathing valve and the wind cap are connected to the second glass layer.

[0011] As a further limitation of the first aspect of the utility model, the breathing valve includes a rotating shaft and a diaphragm, the diaphragm is connected to the rotating shaft, the rotating shaft is connected to the second glass layer, and the diaphragm can rotate along the rotating shaft driven by indoor warm air to open the second through hole.

[0012] As a further limitation of the first aspect of the utility model, the diaphragm is located outside the second through hole, and the area of ​​the diaphragm is larger than the cross-sectional area of ​​the second through hole, so that the second through hole can be sealed to prevent backflow when external air enters.

[0013] As a further limitation of the first aspect of the utility model, the hood includes a hood end cover and a hood enclosure, the hood enclosure is arranged around the second through hole, the hood enclosure is connected to the hood end cover, and a hood air outlet is opened at the connection portion between the hood enclosure and the hood end cover.

[0014] As a further limitation of the first aspect of the present utility model, the hood end cover is conical.

[0015] As a further limitation of the first aspect of the utility model, the hood enclosure is cylindrical and perpendicular to the second glass layer and is arranged around the second through hole.

[0016] As a further limitation of the first aspect of the present utility model, the first through hole and the second through hole are both round holes.

[0017] As a further limitation of the first aspect of the present invention, the first through hole is opened at the top position of the first glass layer.

[0018] As a further limitation of the first aspect of the utility model, the second through hole is opened at the bottom position of the second glass layer.

[0019] In a second aspect, the utility model provides a door and window system.

[0020] A door and window system comprises the structure for increasing the temperature of door and window glass in winter as described in the first aspect of the utility model.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The utility model innovatively develops a structure for increasing the temperature of door and window glass in winter. Without adding extra energy, by increasing the temperature of doors and windows, it effectively reduces the heat radiation loss of the human body, reduces the feeling of cold wind caused by the sinking of air near doors and windows, and improves the thermal comfort of indoor personnel.

[0023] 2. The utility model innovatively develops a structure for increasing the temperature of door and window glass in winter. A breathing valve that can be opened with a micro-pressure to prevent backflow is arranged at the cold air outflow hole (i.e., the second through hole). Under normal circumstances, it can be opened by thermal pressure or wind pressure, and at the same time, backflow caused by the suction effect of the vortex destroying the wind hood is avoided in special circumstances.

[0024] 3. The utility model innovatively develops a structure for increasing the temperature of door and window glass in winter. A miniature hood is arranged outside the cold air outflow hole (i.e., the second through hole). Through the shielding effect of the hood end cover and the hood enclosure, the reflection and vortex formed by the outdoor air flow at the wall are utilized to create a negative pressure area at the hood outlet, thereby increasing the suction force of the cold air outflow and enhancing the ventilation effect. To a certain extent, the greater the wind force, the more obvious the suction effect.

[0033] Embodiment 1:

[0034] like Figure 1 As shown, Embodiment 1 of the utility model provides a structure for increasing the temperature of door and window glass in winter, comprising: a first glass layer 1 and a second glass layer 8, the first glass layer 1 and the second glass layer 8 are positioned opposite to each other to form an air gap 2, the first glass layer 1 is provided with at least one hot pressing hole 3 (i.e., a first through hole), and the second glass layer 8 is provided with at least one outflow hole 4 (i.e., a second through hole);

[0035] A breathing valve 5 is arranged on one side of the hot pressing hole 3 close to the external environment, a wind cap 6 is arranged outside the breathing valve 5 , and both the breathing valve 5 and the wind cap 6 are connected to the second glass layer 8 .

[0036] In this embodiment, the preferred hot pressing hole 3 and the outflow hole 4 are both one. It can be understood that in some other implementations, multiple holes can be set, which is determined according to the specific insulation environment or processing requirements and will not be elaborated here.

[0037] In this embodiment, the heat-pressing hole 3 can ensure that the indoor air only enters the air gap 2, and the outflow hole 4 ensures that the indoor air can be connected to the outdoors through the heat-pressing hole 3 and the air gap 2 in the room.

[0038] In this embodiment, preferably, the breathing valve 5 includes a breathing valve shaft 5-2 and a breathing valve diaphragm 5-1, the breathing valve diaphragm 5-1 is connected to the breathing valve shaft 5-2, the breathing valve shaft 5-2 is connected to the second glass layer 8, and the breathing valve diaphragm 5-1 can rotate along the breathing valve shaft 5-2 driven by indoor warm air to open the outflow hole 4.

[0039] In this embodiment, preferably, the breathing valve diaphragm 5-1 is located on the outside of the outflow hole 4, and the area of ​​the breathing valve diaphragm 5-1 is larger than the cross-sectional area of ​​the outflow hole 4. Under normal circumstances, it can be opened by heat pressure or wind pressure, and avoids backflow caused by the vortex destroying the suction effect of the wind hood under special circumstances.

[0040] In this embodiment, preferably, the hood 6 includes a hood end cover 6-2 and a hood enclosure 6-1, the hood enclosure 6-1 is arranged around the outflow hole 4, the hood enclosure 6-1 is connected to the hood end cover 6-2, and a hood air outlet 6-3 is opened at the connection portion between the hood enclosure 6-1 and the hood end cover 6-2; preferably, the hood end cover 6-2 is conical.

[0041] In this embodiment, preferably, the hood enclosure 6 - 1 is cylindrical and vertically arranged with the second glass layer 8 around the outflow hole 4 .

[0042] In this embodiment, through the shielding effect of the hood end cover 6-2 and the hood enclosure 6-1, the reflection and vortex formed by the outdoor air flow at the wall are utilized to create a negative pressure area at the hood outlet 6-3, thereby increasing the suction force of the cold air outflow and enhancing the ventilation effect.

[0045] The specific working principle of the above structure is:

[0046] During indoor heating in winter, the indoor air has a certain temperature gradient, and a neutral surface will be formed indoors. The upper side of the neutral surface is a positive pressure zone of thermal pressure, and the lower side of the neutral surface is a negative pressure zone of thermal pressure. The air in the lower part of the room is heated by the heat source and rises to form a heat plume 7. Under the action of the upper positive pressure thermal pressure, it flows into the door and window channel through the thermal pressure hole 3 and enters the air gap 2. It is continuously reduced to cold air through heat exchange with the first glass layer 1 and the second glass layer 8. The cold air sinks and flows out of the room through the outflow hole 4 under the action of external suction. Through the long-term effect of this process, the glass temperature can be effectively increased, the heat radiation loss of indoor personnel can be reduced, and the thermal comfort can be improved. In addition, the increase in glass temperature reduces the feeling of cold wind caused by the sinking of air near the glass in the room, further improving the uniformity and comfort of indoor temperature.
