Description

Technical Field

[0001] This utility model relates to the field of vertical elevator technology, and in particular to a ventilation structure for an elevator. Background Technology

[0002] The elevator car of a vertical elevator is a relatively sealed space. To ensure air circulation inside the elevator car, gaps are usually set between the side walls and the bottom of the elevator car, and between the side walls and the top of the elevator car for ventilation. However, during the operation of the elevator car, due to the high speed of the elevator car, the air entering the elevator car through the gaps flows at a relatively fast speed. Air is blown into the elevator car quickly from the top or bottom of the elevator car, causing discomfort to the passengers. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and to provide a ventilation structure for an elevator.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A ventilation structure for an elevator includes an elevator car side panel. N parallel vertical strip-shaped ventilation openings are provided on the elevator car side panel. Four support blocks arranged in a rectangular array are installed around the strip-shaped ventilation openings on the outer side of the elevator car side panel. A semi-threaded bolt arranged vertically is installed on each support block. A wind deflector grille, tightly fitted to the elevator car side panel, is installed between the four semi-threaded bolts. A compression spring is fitted onto each semi-threaded bolt and sandwiched between the support block and the wind deflector grille. The wind deflector grille has N-1 wind deflector strips and two wind deflector plates, symmetrically positioned vertically. The N-1 wind deflector strips are located between the two wind deflector plates.

[0005] Wherein, the distance between two adjacent strip-shaped ventilation openings is greater than the height of the strip-shaped ventilation opening, the distance between the wind deflector strip and an adjacent wind deflector strip or wind deflector plate is equal to the distance between two adjacent strip-shaped ventilation openings, the thickness of the wind deflector strip is equal to the distance between two adjacent strip-shaped ventilation openings, and the thickness of the wind deflector plate is greater than the thickness of the wind deflector strip.

[0006] The width of the wind deflector is twice the width of the wind deflector strip, and the length of the wind deflector and the length of the wind deflector strip are equal to the length of the strip-shaped ventilation opening.

[0007] The wind deflector has a V-shaped groove on the side away from the wind deflector strip.

[0008] The first dust filter screen is installed on the side of the wind deflector grille away from the elevator car side panel.

[0009] The inner side of the elevator car side panel is equipped with a second dust filter screen that covers the strip-shaped ventilation opening.

[0010] The beneficial effects of this utility model are as follows: When the elevator is stationary, the gap between the wind deflector strip and the adjacent wind deflector strip or wind deflector plate is aligned with the strip-shaped ventilation opening, allowing air to circulate freely inside and outside the elevator car, thus achieving the purpose of elevator car ventilation; when the elevator car is running, the wind deflector plate, under the action of air resistance in the elevator shaft, causes the wind deflector grille to move in the opposite direction to the direction of elevator car movement, so that the wind deflector grille blocks the strip-shaped ventilation opening, preventing air from rushing into the elevator car and causing discomfort to the passengers; thus, the elevator car can be ventilated when stationary, and ventilation is suspended when the elevator car is running.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] like Figures 1 to 4 As shown, an elevator ventilation structure includes an elevator car side panel 1, on which four vertically parallel strip-shaped ventilation openings 2 are provided.

[0014] Four support blocks 3 arranged in a rectangular array are installed on the outer side of the elevator car side panel 1 around the strip-shaped ventilation opening 2. Each support block 3 is equipped with a semi-threaded bolt 4 arranged vertically. A wind deflector 5 that fits tightly against the elevator car side panel is installed between the four semi-threaded bolts 4. A compression spring 8 is fitted on the semi-threaded bolt 4 and sandwiched between the support block 3 and the wind deflector 5. The support block 3 is provided with a guide hole 12 arranged vertically. The semi-threaded bolt 4 is fitted into the guide hole 12 and moves axially along the guide hole 12. The tail of the semi-threaded bolt is screwed to the wind deflector 5.

[0015] The wind deflector grille 5 is provided with 3 wind deflector strips 6 and two wind deflector plates 7. The two wind deflector plates 7 are symmetrically arranged vertically, and the 3 wind deflector strips 6 are located between the two wind deflector plates 7.

[0016] The distance between two adjacent strip vents 2 is greater than the height of the strip vent 2. The distance between the wind deflector 6 and the adjacent wind deflector 6 or wind deflector 7 is equal to the distance between two adjacent strip vents 2. The thickness of the wind deflector 6 is equal to the distance between two adjacent strip vents 2. The thickness of the wind deflector 7 is greater than the thickness of the wind deflector 6. The width of the wind deflector 7 is twice the width of the wind deflector 6. The length of the wind deflector 7 and the length of the wind deflector 6 are equal to the length of the strip vent 2.

[0017] The side of the wind deflector 7 away from the wind deflector strip 6 is provided with a groove 9 with a V-shaped cross section to increase the wind resistance of the wind deflector 7.

[0018] A first dust filter 10 is installed on the side of the wind deflector 5 away from the elevator car side panel, and a second dust filter 11 is installed on the inner side of the elevator car side panel 1, covering the strip-shaped ventilation opening. The first dust filter 10 and the second dust filter 11 work together to reduce the amount of dust entering the elevator car.

[0019] When the elevator is stationary, under the action of the spring force of the compression spring 8, the gap between the wind deflector 6 and the adjacent wind deflector 6 or wind deflector 7 is aligned with the strip ventilation opening 2, so that the air inside and outside the elevator car can circulate freely, thereby achieving the purpose of ventilation of the elevator car.

[0020] When the elevator car is moving downwards, the wind deflector 7 located at the bottom of the wind deflector 5 moves upwards due to the air resistance in the elevator shaft, causing the wind deflector 5 to block the strip ventilation opening 2 until the bolt head of the half-threaded bolt 4 located below the wind deflector 5 abuts against the bottom end of the support block 3 located below the wind deflector 5, thus preventing air from rushing into the elevator car and causing discomfort to the passengers.

[0021] When the elevator car moves upward, the wind deflector 7 located at the top of the wind deflector 5 moves downward due to the air resistance in the elevator shaft, causing the wind deflector 5 to block the strip ventilation opening 2 until the bolt head of the half-threaded bolt 4 located above the wind deflector 5 abuts against the bottom end of the support block 3 located above the wind deflector 5, thus preventing air from rushing into the elevator car and causing discomfort to the passengers.
