Abstract

PURPOSE:To perform an indoor ventilation and enable a desired indoor temperature to be held by a method wherein a shape memory alloy coil spring is fixed between one end of a sliding plate and a fixing frame. CONSTITUTION:A sliding plate 10 oppositely facing against ventilation holes 4 and 5 formed in a grid-like manner in a fixing frame 1 is reciprocated and closes near the ventilation holes 4 and 5. The sliding plate opens the ventilation holes while the plate being moved away from them. A communication between an indoor area and an outdoor area is closed or a communication between an indoor area and an outdoor area is attained by the ventilation holes 4 and 5 so as to perform indoor air ventilation. That is, an automatic repetition operation is carried out under an action of a biasing spring 31 and a shape memory alloy coil spring 30 fixed between both ends of the sliding plate 10 and the fixing frame 1, respectively. The sliding plate 10 approaches the ventilation holes 4 and 5 of the fixing frame 1 and the sliding plate 10 is controlled by a closing lock mechanism such that it is not automatically operated. The sliding plate is moved away from the ventilation holes 4 and 5 of the fixing frame 1 and the sliding plate 10 is controlled by the opening lock mechanism such that the sliding plate is not automatically operated. A closing lock mechanism and an opening lock mechanism are returned to their original positions, thereby the control over the sliding plate 10 is released. With such an arrangement, an indoor temperature adjustment and the ventilation can be optionally and easily carried out.

Description

[Detailed Description of the Invention] [Industrial Application Field] The invention is used to open or close the ventilation hole by attaching it to the window frame or ventilation hole of a building, or to adjust the indoor temperature by automatically opening and closing the ventilation hole. This invention relates to a device designed to provide ventilation.

[Prior Art] Jitsumato No. 1-88241 discloses that a lever that opens and closes the shutter of a ventilation fan is provided with a bias spring that biases the shutter in the direction of closing, and a coil-shaped bias spring that biases the lever in the opposite direction. The N4 structure is equipped with a shape memory alloy member, which is energized at the same time as the fan motor is energized, and is restored and contracted by resistance heating to operate the lever in the direction of opening the shutter against the elasticity of the bias spring. ing. This shutter opening/closing device 7♂ operates the individual shutter blades in a fan-shape around the center of each hinge, so when 1F of wind is applied to the shutter blades, a difference is caused in the fl load applied to the shape memory alloy member, and a constant voltage is applied to the shape memory alloy spring. Even when current flows, the shape memory alloy spring causes irregular movement and the shutter blade cannot be held in the closed or open state.

[Problems to be Solved by the Invention] The present invention uses a fixed plate provided with ventilation holes and a sliding plate that approaches and separates from the ventilation holes of the identification plate, without using shutter blades that operate irregularly. The purpose is to fix the sliding plate at the location where it is activated, ventilate the room, and maintain the required indoor temperature.

[Means for solving the problem] i1) A fixed frame that is attached to a window frame, ventilation hole, etc. of a building, and a structure that allows it to slide in the longitudinal direction of the fixed frame so as to access the window ventilation hole of the identification frame. a sliding plate guided to close the ventilation hole of the window or open the ventilation hole at a distance from the ventilation hole of the window; The sliding plate is fixed by the action of the guide cam and bias spring provided on the fixed frame, which guides the guide pin of the sliding plate so that the sliding plate approaches or moves away from the ventilation hole of the window of the fixed frame. Close the ventilation hole of the frame window and close the ventilation hole. 1. When the ambient temperature is higher than the martensite reverse transformation temperature of the shape memory alloy coil spring, the shape memory alloy coil spring undergoes reverse transformation and returns to the parent phase. An indoor temperature control ventilator comprising a shape memory alloy coil spring that is restored and contracted to move the sliding plate away from the ventilation hole of the window against the elasticity of the bias spring.

(2) Claim (1) comprising an open lock mechanism that approaches the ventilation hole of the window of the fixed frame and maintains the ventilation hole of the window in a closed state.
Room temperature control ventilation system as described.

(3) The indoor temperature control according to claim (1) or (2), wherein the sliding plate has an opening ivy mechanism that is spaced apart from the ventilation hole of the window of the fixed frame and maintains the ventilation hole of the window in an open state. Ventilation equipment.

(4) When the room temperature rises, the bias coil spring moves the sliding plate away from the ventilation hole of the window in the fixed frame, allowing indoor and outdoor air to communicate with each other.5 When the room temperature becomes lower than the martensitic reverse transformation temperature of the shape memory alloy coil spring, shape memory is achieved. The alloy coil spring undergoes reverse transformation and returns to the parent phase, and the sliding plate approaches the ventilation hole of the window of the identification frame to reduce the flow of indoor and outdoor air. An indoor temperature control ventilator equipped with an opening lock mechanism and a closing vine mechanism that fixes a sliding plate that automatically repeats its operation in the activated position.

[Function] The present invention reciprocates the sliding plate facing the ventilation hole formed in the shape of a screen made in the fixed frame, approaches the ventilation hole and closes it, and opens the ventilation hole away from the ventilation hole. Bias springs and shape memory alloys are installed between both ends of the sliding plate and the fixed frame, respectively, to close the flow between the indoor and outdoor areas or to connect the indoor and outdoor areas through ventilation holes to ventilate the indoor air. The action of the coil spring automatically repeats the rotation, and the sliding plate is brought close to the ventilation hole of the fixed frame, and the opening lock mechanism is controlled so that the sliding plate does not operate automatically. is separated from the ventilation hole of the fixed frame, the opening lock mechanism is used to control the sliding plate so that it does not operate automatically, and the closing locking mechanism and the opening locking mechanism are returned to their original positions to release control of the sliding plate. This is what I did.
