Abstract

The utility model provides an automatic window closing device for horizontal sliding windows, which can automatically close an open window when it rains. The device with simple structure comprises a motor, a redactor, a gear, a gear rack, a bracket and a humidity sensor, wherein the gear rack is fixed at the upper edge of the inner side of a window frame, the bracket is fixed at the upper edge ofthe inner side of a window door, the motor is mounted on the reducer, an output shaft of the motor is connected with an input shaft of the reducer, the gear is installed on an output shaft of the reducer, the reducer is fixed on the bracket, the gear is meshed with the gear rack, the humidity sensor is mounted on the outer side of the window frame, and the humidity sensor is connected with the motor in series. The humidity sensor is closed when it rains, and a travel switch is also closed when the window door is opened; and under such a condition, the motor rotates to drive the reducer into rotation, which further drives the gear to rotate so as to be meshed with the gear rack. Then under the acting force generated by the meshing between the gear and the gear rack, the window door is movedto be closed.

Description

The window self closing device

Technical field

The utility model relates to a kind of building window opening closure, particularly relates to the window self closing device.

Background technology

When people go out, often the window in the family is opened, so that the fresh cleaning of family air, still, when rainy, the rainwater into unlimited window that tends to waft drenches floor, furniture and other facilities in the room.

The patent No. is that the window device is closed in a kind of blowing and raining of CN02153777.1 automatically, provide a kind of blowing and raining to close the window device automatically, described device is included in the window bottom compartment outside that can open and close wind sensor and rain sensor is housed, also include circuits for triggering and transmission mechanism, described wind sensor and rain sensor are connected with circuits for triggering in the described device, and circuits for triggering are connected with transmission mechanism.This beneficial effect of the invention is to use this device, can accomplish that window is closed automatically when running into wind or rain, has reduced because many troubles of being brought in wind or the rain inlet chamber are avoided the personal injury that might take place.

The patent No. is the window self closing device of CN88216529.1, can be at rain, snow induction automatic close window family.Constitute by electromagnetic controller, manual button, the wind spring that resets etc.When rainwater drenched the open circuit inductor of electromagnetic controller, inductor made electromagnetic coil connect immediately.Produce ferromagnetic upper core and pick up lower core, mention thereby utilize the short horizontal that crosses lower core will open and close piece, this moment, the cross through hole of back shaft opened wide, and the strut that passes across is being with sash to close rapidly under the effect of wind spring.This utility model is simple in structure, and control is reliable, convenient being suitable for.

But the patent No. is that the transmission of window device employing band, complex structure, poor reliability are closed in a kind of blowing and raining of CN02153777.1 automatically; The patent No. is that the window self closing device of CN88216529.1 is not suitable for the flat push type window.

Summary of the invention

The purpose of this utility model provides a kind of window self closing device of horizontal sliding window, and it can close the window of opening automatically when rainy, simple in structure.

In order to achieve the above object, window self closing device of the present utility model comprises motor, reducer, gear, tooth bar, support and humidity sensor;

Tooth bar is fixed on the upper edge of window frame inboard, support is fixed on the upper edge of window inboard, motor mounting is on reducer, the output shaft of motor is connected with input shaft of speed reducer, gear is installed on the output shaft of reducer, and reducer is fixed on the support, the wheel and rack engagement, humidity sensor is installed in the window frame outside, and humidity sensor is connected with motor in series.

Described reducer is a gear reduction unit.

Described gear is an involute spur gear.

The modulus of described tooth bar is identical with the modulus of gear.

Described motor is a supply voltage 220V ac motor.

The window frame left and right sides is equipped with travel switch, and travel switch passes with motor and humidity answers the circuit of device to connect, and the effect of travel switch is after window is closed, and travel switch is disconnected, and motor is just out of service.

Humidity sensor is for what often open, and when not raining, the humidity of air does not reach the humidity of humidity sensor closure, and humidity sensor just is disconnected.

When rainy, humidity sensor is just closed, if window is being opened, then travel switch also is closed, motor will rotate, and motor rotates and drives the reducer rotation, and the reducer rotation driven gear rotates, the wheel and rack engagement, and tooth bar is installed on the window frame, and gear is installed on the window by reducer and support, under the active force of gear and tooth bar engagement generation, window just moves, and window is closed; When window was closed fully, travel switch was just run in the window side, and travel switch will disconnect, and motor is stopped operating.

After rain stopped, the humidity of air did not reach the humidity of humidity sensor closure, and humidity sensor just is disconnected, and at this moment opened the window motor and can not rotate yet, and did not influence the switch of window.

Window self closing device of the present utility model, it can close the window of opening automatically when rainy, simple in structure, and reliable operation is with low cost.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the sectional structure schematic diagram.

Fig. 3 is a partial schematic diagram.

The specific embodiment

Fig. 1 description of symbols: motor 1, reducer 2, tooth bar 3, window frame 4, window 5, travel switch 6.

Fig. 2 description of symbols: humidity sensor 7.

Fig. 3 description of symbols: gear 8, support 9.

Referring to Fig. 2, window self closing device of the present utility model mainly comprises motor 1, reducer 2, gear 8, tooth bar 3, support 9 and humidity sensor 7.

Tooth bar 3 is fixed on the upper edge of window frame 4 inboards, support 9 is fixed on the upper edge of window 5 inboards, motor 1 is installed on the reducer 2, the output shaft of motor 1 is connected with the power shaft of reducer 2, gear 8 is installed on the output shaft of reducer 2, and reducer 2 is fixed on the support 9, gear 8 and tooth bar 3 engagements, humidity sensor 7 is installed in window frame 4 outsides, and humidity sensor 7 is connected in series with motor 1.
