Inward window

Abstract

The invention relates to an inward opening window. The inward opening window comprises a window frame, a window sash, inflatable sealing strips, an inflating device, an exhausting device, a master control circuit board, wherein the window sash is hinged with the window frame, the inflatable sealing strips are arranged on the window frame and used for enclosing a heat insulation broken bridge of the window frame, the inflating device and the exhausting device are used for inflating and deflating the inflatable sealing strips correspondingly, and the master control circuit board is electrically connected with the inflating device and the exhausting device correspondingly, and the window sash turns outdoors from the indoor space to seal the window frame with the end, hinged with the window frame, of the window sash as the fulcrum. Compared with the prior art, the master control circuit board can start the inflating device to inflate the inflatable sealing strips after receiving an inflating signal, so that a cavity formed between the window sash and the window frame is completely insulated, and sealing between the window sash and the window frame is achieved; while the airtightness is improved, corrosion of profiles caused by rainwater seeping into the profiles can be prevented; and the master control circuit board starts the exhausting device to exhaust air in the inflatable sealing strips after receiving an exhausting signal so as to cut off the sealing between the window sash and the window frame and facilitate opening of the window sash.

Description

technical field [0001] The invention relates to a door and window, in particular to an inward opening window. Background technique [0002] Traditional inward opening windows are generally sealed by installing duckbill strips on the sash and window frame, but because duckbill strips are generally installed on the indoor and outdoor frame profiles of the window sash, or installed on the outdoor and outdoor sides of the window frame. On the interior frame profile, so as to realize the sealing of window frame and sash. Although the rubber strip has a certain coefficient of elasticity to prevent deformation and wear of the rubber strip, after a long period of use, it will still be deformed and worn to a certain extent, thereby affecting the sealing performance between the window frame and the window sash. [0003] In addition, because there is no sealing measure at the thermal insulation bridge between the sash and the window frame, when the sash is in the closed state, a cavit...

Problems solved by technology

Although the rubber strip has a certain elastic coefficient to prevent deformation and wear of the rubber strip, after a long period of use, deformation and wear will still occur to a certain extent, thus affecting the sealing performance between the window frame and the window sash

[0003] In addition, since there is no sealing measure at the thermal insulation bridge between the sash and the window frame, when the sash is in the closed state, a cavity will be formed between the sash and the frame bridge. In rainy and snowy weather, rainwater will seep into the cavity and cause corrosion of the internal profiles. Severe rainwater will also seep into the house and cause damage to the wall
