Detailed Description
Fig. 1, 2 and 3 depict a first embodiment of the invention.
In the figure, an electric built-in sunshade hollow glass product with thermal protection comprises hollow glass, a scroll curtain and a scroll curtain retraction and release mechanism, wherein the scroll curtain and the scroll curtain retraction and release mechanism are arranged in the hollow glass, and an upper frame 2, a lower frame 3, a left frame 4 and a right frame 5 are arranged in the hollow glass; the winding and unwinding mechanism of the roller shutter comprises a winding drum 6 and a tubular motor 1 positioned in the winding drum, a curtain cloth 7 is wound on the winding drum 6, a bottom rod 8 is arranged at the free end of the curtain cloth 7, a temperature switch 9 is arranged in the upper frame 2, and the temperature switch 9 is connected in series in a control circuit of the tubular motor.
The glass 10 and the glass 11 are two pieces of plate glass constituting hollow glass, and the sealant 13 is a sealant for the hollow glass. The front baffle 12 and the rear baffle 15 are positioned at the position of the roller shutter retracting mechanism and play an aesthetic role.
The 220V commercial power supplies 24V power to the tubular motor 1 through the controller 16 and the electric wire 17, and controls the tubular motor 1 to rotate forward and backward, the temperature switch 9 is connected in series in the circuit, and the on and off of the temperature switch 9 determines the on and off of the circuit from the controller 16 to the tubular motor 1.
The type of the temperature switch 9 is a normally closed type, and in this embodiment, a KSD9700 type temperature switch is used, and the normally closed type, operating temperature is 60 ℃, and contact capacity is 5A, 250V. The temperature switch 9 is bonded with a single-sided foam adhesive tape 14, so that the temperature switch can be tightly attached to the lower end of the upper frame, and the temperature sensed by the temperature switch is consistent with the temperature at the upper end of the inner cavity of the hollow glass.
The utility model discloses a thermal protection theory of operation describes as follows:
in winter, spring and autumn, when the environmental temperature is lower than 26 ℃, the temperature at the upper end of the cavity inside the hollow glass is lower than 60 ℃, the contact of the temperature switch 9 is normally closed, and the electric roller shutter system works normally.
In summer, when the environmental temperature is higher than 26 ℃, when the curtain cloth 7 is put down and sunlight irradiates on the curtain cloth 7, the curtain cloth 7 blocks the sunlight to generate heat, and the temperature of the upper end of the inner cavity of the hollow glass is increased to be more than 60 ℃. According to the test, the temperature of the upper end of the inner cavity of the hollow glass can reach 75 ℃ when the hollow glass is hottest in Nanjing area. At the moment, the contact of the temperature switch 9 is disconnected, and the electric roller shutter system cannot work, so that the tubular motor 1 is prevented from being damaged due to the use in a high-temperature environment. When sunlight turns to and does not shine on cavity glass, cavity glass inside cavity upper end temperature reduces to be less than 60 ℃ after, temperature switch 9 contact will resume closed, and electronic spool curtain system can normally work.
In this embodiment, the sun shade is a roller blind, but a blind, a pleated blind, or a cellular blind may be used, and the use cases are not illustrated.
In the above embodiments, the technical part not described in detail can refer to the technical index requirements specified in the JG/T255-2009 « built-in sunshade hollow glass product mobile standard.
