Ventilation seat

Abstract

The invention discloses a ventilation seat which comprises a chair seat (1) and a chair-back (2) supported by the chair seat (1), wherein at least one duct (3) is arranged in the chair-back (2), an air inlet (31) of each duct is arranged below the chair-back (2) and is communicated with an air supply outlet of an external air supply device (7), and an air outlet (32) of each duct is arranged behind the chair-back (2). After the external air supply device is started, low temperature air passes through the duct, blows audiences and can efficiently fulfill the functions of ventilation and cooling.

Description

technical field [0001] The invention relates to seats, in particular to a ventilated seat used in large indoor and outdoor public places such as stadiums. Background technique [0002] In the design of large public places such as sports venues, the issue of ventilation and cooling for the audience must be considered. For example, in existing sports venues, cooling equipment (such as air conditioners) is installed on the top, and it is difficult to cool the audience due to the distance from the ground. For example, the outdoor space of an outdoor football field is not airtight. Ordinary cooling equipment will not be able to cool down the audience at that time, making the audience suffer from the hot air outside. In severe cases, it may even cause heat stroke and life-threatening for the audience. For another example, the space in the common gymnasium is relatively large, and to make the gymnasium reach a comfortable temperature, the cooling device must be turned on before op...

AI Technical Summary

Problems solved by technology

For example, in existing stadiums, cooling equipment (such as air conditioners) are installed at the top, and it is difficult to cool the audience due to the distance from the ground.

For example, the outdoor space of an outdoor football field is not airtight. Ordinary cooling equipment will not be able to cool the audience at that time, making the audience suffer from hot air outdoors. In severe cases, it may even cause heatstroke and life-threatening danger to the audience.

Another example is that the space in ordinary gymnasiums is relatively large. To achieve a comfortable temperature in the gymnasium, the cooling device must be turned on before opening, so that the indoor temperature will gradually drop.

In addition, there are no spectators in some areas of the venue, but in order to achieve the cooling effect, the gymnasium is still forced to turn on the cooling device, resulting in a great waste of energy

[0003] In the prior art (such as automobiles), there is a type of ventilated seat with active ventilation and cooling equipment, and the generated wind is directly blown to the inside of the seat, making the human body on the seat feel uncomfortable.

In addition, due to the high cost, it cannot be widely used
