Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and more specifically, to a glass anti-fogging device for metal doors and windows. Background Technology
[0002] Metal door frames are frame structures made of metal used to fix and support door and window glass. Metal door frames are characterized by their sturdiness, wear resistance, corrosion resistance, and long service life, and are widely used in various types of doors and windows in the construction industry, such as balcony doors and windows in residential and commercial buildings. Glass is installed on the inner surface of the metal door frame, together forming the door and window structure. However, existing technology has the following shortcomings in its use:
[0003] Most existing doors and windows do not have anti-fogging function. When there is a large temperature difference between indoors and outdoors, the glass will fog up, which will affect the light transmittance of the glass and make it difficult to see outside through the glass.
[0004] Therefore, there is an urgent need for a glass anti-fogging device for metal doors and windows to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an anti-fogging device for metal doors and windows. This device solves the problem that most existing doors and windows do not have anti-fogging capabilities, and fogging occurs when there is a large temperature difference between indoors and outdoors. This not only affects the light transmittance of the glass but also makes it difficult to see outdoors through the glass.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] The application is as follows:
[0008] A glass anti-fogging device for metal doors and windows includes a frame, an installation groove on the inner surface of the frame, a glass body inside the installation groove, a cavity on the inner surface of the frame, a guide rod fixedly installed laterally on the inner surface of the cavity, a first slider slidably connected to the guide rod, a heater fixedly installed on the upper surface of the first slider, an air duct installed at the output end of the heater, a plurality of air outlets arranged longitudinally at equal intervals on the outer surface of the air duct, and a V-shaped air guide plate fixedly installed on the inner surface of the air outlets.
[0009] The V-shaped air guide vane includes a first connecting piece and a second connecting piece, the first connecting piece and the second connecting piece are symmetrically arranged, and the V-shaped air guide vane is arranged laterally.
[0010] A reciprocating motor is fixedly installed on the inner surface of the cavity, and a lead screw is fixedly connected to the output end of the reciprocating motor. A second slider is threaded onto the lead screw.
[0011] As a preferred technical solution of this application, the included angle between the first connecting piece and the second connecting piece is 60°-100°, and the V-shaped air guide plate is integrally formed.
[0012] As a preferred technical solution of this application, the V-shaped air guide is located in the middle of the air outlet, and the length of the V-shaped air guide is the same as the diameter of the air outlet.
[0013] As a preferred technical solution of this application, the end of the air duct away from the heater is fixedly connected to the upper surface of the second slider.
[0014] As a preferred technical solution of this application, the end of the lead screw away from the reciprocating motor is rotatably connected to the inner surface of the cavity through a bearing.
[0015] As a preferred technical solution of this application, a sealing strip is fixedly connected to the inner surface of the mounting groove, and the outer surface of the glass body is in contact with the sealing strip.
[0016] As a preferred technical solution of this application, the guide rod is parallel to the lead screw, and the first slider is located directly above the second slider.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. When the reciprocating motor and the heater are running, the guide rod, the first slider, the air duct, the lead screw and the second slider work together to drive the heater and the air duct to move laterally back and forth. Hot air is discharged through multiple air outlets, which can effectively prevent the glass body from fogging and ensure the light transmittance of the glass body.
[0019] 2. By setting multiple V-shaped air guides, when hot air is discharged from the air outlet, the V-shaped air guides can guide and divert the hot air. When the air guide moves horizontally back and forth, it can ensure the effect of blowing and heating one side of the glass body surface, and avoid the situation of uneven defogging caused by concentrated hot air blowing out.

[0029] Example:
[0030] like Figure 1-5As shown, this embodiment proposes a glass anti-fogging device for metal doors and windows, including a frame 1. An installation groove 2 is formed on the inner surface of the frame 1, and a glass body 3 is disposed inside the installation groove 2. A cavity 4 is formed on the inner surface of the frame 1, and a guide rod 5 is horizontally fixedly installed on the inner surface of the cavity 4. A first slider 6 is slidably connected to the guide rod 5, and a heater 7 is fixedly installed on the upper surface of the first slider 6. When the heater 7 is started, a duct 8 is installed at the output end of the heater 7. When the heater 7 is running, hot air is introduced into the duct 8. Several longitudinally equidistant air outlets 9 are formed on the outer surface of the duct 8, allowing the hot air to be discharged through these outlets. A V-shaped air guide plate 10 is fixedly installed on the inner surface of the outlet 9, which can heat one side of the glass body 3 by blowing air.
[0031] The V-shaped air guide 10 includes a first connecting piece 11 and a second connecting piece 12. The first connecting piece 11 and the second connecting piece 12 are symmetrically arranged, and the V-shaped air guide 10 is arranged laterally. The included angle between the first connecting piece 11 and the second connecting piece 12 is 60°-100°. The V-shaped air guide 10 is integrally formed and is located in the middle of the air outlet 9. The length of the V-shaped air guide 10 is the same as the diameter of the air outlet 9. Through the V-shaped air guide 10, the hot air delivered by the air duct 8 can be guided and diverted, so that the hot air can be more evenly diffused to both sides after being blown out of the air outlet 9, increasing the contact area between the hot air and the surface of the glass body 3, and allowing the fog on the surface of the glass body 3 to be more evenly dispersed by the hot air.
[0032] A reciprocating motor 13 is fixedly installed on the inner surface of the cavity 4. A lead screw 14 is fixedly connected to the output end of the reciprocating motor 13. When the reciprocating motor 13 is started, the lead screw 14 is rotated. A second slider 15 is threaded onto the lead screw 14. The end of the air duct 8 away from the heater 7 is fixedly connected to the upper surface of the second slider 15. The rotating lead screw 14 can drive the second slider 15 to move horizontally. The air duct 8, the first slider 6, and the heater 7 move to the right synchronously with the second slider 15. The first slider 6 is guided by the guide rod 5. When the air duct 8 moves back and forth, the blowing and heating effect on the glass body 3 can be guaranteed.
[0033] like Figure 2 As shown, the end of the lead screw 14 away from the reciprocating motor 13 is rotatably connected to the inner surface of the cavity 4 through a bearing. The bearing ensures the stability of the lead screw 14 during rotation.
[0034] like Figure 1 and Figure 3 As shown, a sealing strip 16 is fixedly connected to the inner surface of the mounting groove 2, and the outer surface of the glass body 3 is in contact with the sealing strip 16. The sealing strip 16 ensures the airtightness between the glass body 3 and the frame 1 and prevents air leakage.
[0035] like Figure 2 As shown, the guide rod 5 is parallel to the lead screw 14, and the first slider 6 is located directly above the second slider 15.
[0036] The working principle of the above embodiment is as follows: Both the heater 7 and the reciprocating motor 13 are electrically connected to an external control power supply. When fogging occurs on the surface of the glass body 3, the heater 7 and the reciprocating motor 13 are started. When the reciprocating motor 13 drives the lead screw 14 to rotate clockwise, it drives the second slider 15 to move to the right. The air duct 8, the first slider 6, and the heater 7 move to the right synchronously with the second slider 15. The guide rod 5 guides the first slider 6. When the reciprocating motor 13 drives the lead screw 14 to rotate counterclockwise, it drives the second slider 15 to move to the left. The air duct 8, the first slider 6, and the heater 7 then move to the left. When the heater 7 is running, hot air is introduced into the air duct 8 and finally discharged through multiple longitudinally equidistant air outlets 9. This heats one side of the glass body 3. At the same time, the V-shaped air guide vanes 10 guide and divert the hot air from the air duct 8, allowing the hot air to diffuse more evenly to both sides after being blown out of the air outlets 9. This increases the contact area between the hot air and the surface of the glass body 3, allowing the fog on the surface of the glass body 3 to be dispersed more evenly by the hot air. This improves the anti-fogging and defogging effect on the glass body 3 and avoids uneven defogging caused by concentrated hot air blowing.
[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
