Embodiment 1

[0035] like figure 1 and 2 As shown, the solar cooker with the function of stretching and shrinking made of soft reflective film includes a support frame 1 and a concentrating device 2, and the concentrating device 2 includes an umbrella-shaped frame body 21 with a concave structure, and a solar cooker for reflecting sunlight. Flexible reflective film 22 and the fixing device 23 that is used to fix flexible reflective film 22 on the umbrella-shaped frame body 21, flexible reflective film 22 and umbrella-shaped frame body 21 constitute a solar light reflector that can irradiate on the flexible reflective film 22 And gather at the focal point of the concave mirror. The solar cooker with expansion and contraction functions made of soft reflective film of the present invention has the advantages of light weight, space saving and convenient transportation.

[0036] like image 3 , 4 , 5, 6, 7, and 8, the support frame 1 includes a connector 11, three base support rods 12, an ad...

Abstract

The invention relates to an unfolding and folding type solar cooker made from a flexible reflective film. The solar cooker comprises a support frame and a light condensing device used for reflecting solar light, wherein the light condensing device comprises an umbrella-shaped framework body with a recessed structure, the flexible reflective film used for reflecting the solar light and a fixing device; and the flexible reflective film, the fixing device and the umbrella-shaped framework body form a concave mirror capable of reflecting the solar light irradiated on the flexible reflective film and condensing the solar light at the focus. The unfolding and folding type solar cooker made from the flexible reflective film has the advantages that by using the detachable framework body and the light condensing device with unfolding and folding functions, space occupied by the solar cooker during storing and transporting is greatly reduced; and by using the flexible reflective film as a light condensing plate of the solar cooker, the weight of the solar cooker is greatly reduced. The unfolding and folding type solar cooker made from the flexible reflective film is light in weight, is convenient to disassemble and install, does not affect cleanliness and saves space during storing and transporting.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization devices, in particular to a solar cooker with stretching and shrinking functions made of a soft reflective film. Background technique [0002] A solar cooker is a device that uses solar radiation to obtain heat by concentrating light for heating. It does not burn any fuel and has no pollution. It is currently popularized and used. Although solar cookers have been well promoted and used, most of the concentrating plates used in solar cookers are made of hard materials, such as metal plates, cement plates with lenses, glass plates, etc., which have the disadvantage of taking up a lot of space. It is also relatively heavy and difficult to carry. It is also placed outdoors in windy and rainy days, and it is easy to cause aging and damage to the solar cooker, which also limits the use of the solar cooker to a certain extent. Contents of the invention [0003] The object of the prese...
