Abstract

An energy-saving door curtain relates to a door curtain or a curtain, in particular to an energy-saving door curtain made of solar panels. It has a foldable curtain body, which is suspended on the door and window frame through the upper beam plate 1. The curtain body is formed by connecting 2 to 16 solar panels 3 with airtight cavities. A gasket 7 is provided between the curtain body and the door and window frame. There are built-in magnetic sheets 5 at both side edges of the cavity of the solar panel, which interact with corresponding iron sheets 8 on the gasket. The solar panel of the utility model has a closed cavity, and uses magnetic force to closely contact with the frames of doors, windows, and curtain walls to block the flow of indoor and outdoor air, and can effectively control the conduction, convection, and radiation of heat energy. Heat exchange has the positive effect of reducing energy consumption for cooling in summer and heating in winter.

Description

Energy-saving door curtain

technical field

The utility model relates to a door curtain or curtain, in particular to an energy-saving door curtain made of sunlight panels.

Background technique

The glass doors and windows and glass curtain walls commonly used in existing buildings, because of the large gaps in the frame, convection of indoor and outdoor air will occur. In addition, the metal frame has a large thermal conductivity, and the heat radiation caused by transparent glass is also obvious. The above channels all cause indoor air pollution. The occurrence of external heat transfer will affect the effect of heating and air conditioning.

In the prior art, some solar panels are used to replace door and window glass, which can properly reduce the heat radiation of the glass, but it does not solve the problems of heat conduction and air convection of the metal frame. There is also a glass film with reflective function, which can reduce indoor sunlight and reduce air-conditioning cooling energy consumption in summer when pasted on the glass. However, on the contrary, heating energy consumption needs to be increased in winter, and the heat conduction and air convection problems of the metal frame cannot be solved.

Contents of the invention

The purpose of this utility model is to provide a new type of energy-saving door curtain, to properly control the conduction, convection and radiation of heat energy, to reduce indoor heat in summer, reduce energy consumption of air-conditioning refrigeration, reduce indoor heat loss in winter, and reduce heating energy consumption. Purpose.

The energy-saving door curtain disclosed by the utility model has a foldable curtain body, which is suspended on the door and window frame through the upper beam plate, and is characterized in that the curtain body is connected by 2 to 16 sun panels with airtight cavities There is a gasket between the curtain body and the door and window frame; magnetic sheets are built in the edges of the cavity on both sides of the sun panel, which interact with the corresponding iron sheets on the gasket.

In the energy-saving door curtain disclosed by the utility model, the sunlight plate constituting the curtain body has an airtight cavity, which increases the thermal resistance of the curtain body and reduces heat conduction. In addition, the utility model utilizes the magnetic force to closely contact the frames of the doors, windows and curtain walls to block the flow and exchange of indoor and outdoor air, which can reduce the convective exchange of energy. Moreover, the solar panel adopted by the utility model has a certain reflectivity to light. Putting down the curtain body in summer can reduce indoor radiant heat gain and reduce energy consumption of air-conditioning refrigeration, and retracting the curtain body in winter can ensure sufficient indoor light. Since the curtain body of the utility model is foldable, it is easy to put it down and put it away. In a word, the utility model can effectively control the conduction, convection and radiation of heat energy, reasonably control the heat exchange between indoor and outdoor according to different seasons, and has the positive effect of reducing the energy consumption of cooling in summer and heating in winter.

Accompanying drawing part discloses the specific embodiment of the utility model, wherein:

Fig. 1 is the front view of the flip-type energy-saving door curtain;

Fig. 2 is the left side view of the flip-type energy-saving door curtain;

Fig. 3 is the front view of the push-pull energy-saving door curtain;

Fig. 4 is the left side view of the push-pull energy-saving door curtain.

Detailed ways

As shown in Figure 1 and Figure 2, the energy-saving door curtain disclosed by the utility model is a flip type, that is, the curtain body is formed by connecting three solar panels 3 through adhesive tapes 4, and each solar panel can be used for 180° Turn over to realize the folding of the curtain body.

As shown in Figure 3 and Figure 4, the energy-saving door curtain disclosed by the utility model is a push-pull type, and the curtain body is formed by overlapping two sun panels 3, wherein the upper one is fixed, and the lower one can be pushed up and down. Movement, the crossbar 9 at the joint of the two is provided with an interacting magnetic block or iron block 10.

The solar panel 3 used in the utility model is made of polycarbonate and has a two-layer through cavity. When in use, seal the cavity around the cavity to form an airtight cavity to increase its thermal resistance. value. Since the above-mentioned solar panel is a common and commonly used ordinary decorative profile in the market, its structure will not be explained too much.

In the above two embodiments, a gasket 7 is provided between the curtain body and the door and window frame. There are built-in magnetic sheets 5 at both side edges of the cavity of the solar panel, which interact with corresponding iron sheets 8 on the gasket. Apparently, the above-mentioned magnetic sheet 5 and iron sheet 8 can be exchanged, and the effect is the same.

In addition, the upper beam plate 1 of the present utility model is provided with a hook 2, and correspondingly, a hanging ring 6 is provided on the lowermost sun plate.
