Natural convection type ventilating and insulating door and using method thereof

Abstract

The invention relates to a natural convection type ventilating and insulating door and a using method thereof. The natural convection type ventilating and insulating door comprises an inside door sheet, an outside door sheet, a cavity and an insulating layer, wherein the cavity is formed between the inside door sheet and the outside door sheet and is used for air circulation; the insulating layer is positioned on the inner side of the cavity; four electric louver structures are respectively arranged on the upper side and the lower side of the inside door sheet and the upper side and the lower side of the outside door sheet; structures of the four electric louver structures are staggered from one another; the four electric louver structures respectively communicate with the cavity; each of the four electric louver structure can be in an opening state, a semi-opening state and a closing state; an upper electric movable insulating baffle and a lower electric movable insulating baffle are arranged in the cavity; the upper electric movable insulating baffle is arranged between the electric louver structures on the upper side; the lower electric movable insulating baffle is arranged between the electric louver structures on the lower side; and each of the upper electric movable insulating baffle and the lower electric movable insulating baffle has a horizontal working state and a vertical working state. By an air natural convection principle, ventilation is carried out by an air interlayer in the cavity, the quality of indoor air is improved, an indoor hot environment is also improved, and energy consumption of air conditioners or heating is reduced effectively.

Description

technical field [0001] The invention relates to a door, in particular to a natural convection ventilation heat preservation door and a using method thereof. Background technique [0002] It is one of the most important indoor ventilation methods of buildings to use the outer door of the room for ventilation. However, due to the large amount of ventilation when the door is opened, the heat or cold in the room will be quickly lost, which is not conducive to energy saving in the room; on the other hand, opening the door for ventilation will also have a negative impact on indoor security and privacy. Use ventilation holes, ventilation grilles, ventilation louvers, etc. to ventilate the outer door of the room. The ventilation power can only rely on the pressure difference between the indoor and the outdoor, and the ventilation effect is not necessarily ideal. [0003] At present, there are also some relevant public documents published. For example, the utility model patent with ...

Problems solved by technology

This patent utilizes the principle of natural convection, which can realize ventilation, but it is difficult to play the role of heat preservation

Another example is the invention patent whose authorized notification number is CN 101356338 B, which specifically discloses a ventilation door, including an indoor side panel and an outdoor side panel, a first passage, a second passage, a first connecting pipe part, a first ventilation part, a second ventilation part, Insulation materials, the third channel, the fourth channel, etc., although they can continue to perform the ventilation function of natural convection, but the structure is too complicated, and the working conditions that do not need ventilation are not considered, and energy consumption is sometimes required in terms of heat preservation
