Abstract

A solar cooker able to cook rice or water indoors features that a tracking mechanism is installed on the focusing point of reflecting condenser, an elbow with plane mirror at its corner and lens at its vertical part is installed above the focal point of said condensing reflector, the horizontal end of said elbow is connected to the light-transmitting guide consisting of glass tube and the elbow of glass tube with plane mirror at its corner, and the bottom of pot or kettle is installed in the room. The sunlight irradiating the reflecting condenser is reflected to the lens and is transmitted to the bottom of the pot through the light guide.

Description

Solar cooker

The utility model relates to a kind of solar cooker, especially the solar cooker that can heat up water in the kitchen and cook as common kitchen range.

At present, the solar cooker that is used by people is to do a support on the focus of mirror condenser, and when solar irradiation was mapped to mirror condenser, sunshine was focused on the focus, and the sunshine of " being concentrated " is passed to energy and is placed on the food of roasting on the support.Such solar cooker, people must roast outdoor, and solar cooker must be placed on eaily local, so existing solar cooker is not suitable for using in populous, built-up city.

The purpose of this utility model provides a kind of solar energy that utilizes at the indoor solar cooker of heating up water and cooking.

The purpose of this utility model is achieved in that the floor stand of the mirror condenser that follower has been installed is fixedly installed to the roof, 90 ° the elbow that the cross section that can rotate with mirror condenser is the glass mirror annulus is installed above the focus of mirror condenser, the two ends of elbow are towards level and vertical direction, have one all to become 135 ° with level and vertical direction in its corner, vertical height, the elliptic plane mirror that horizontal length equates with the elbow caliber, the circle core shaft of the rotation track of the follower of mirror condenser is the central axis of bend horizontal part, be equipped with in the vertical component of elbow one with the confocal convex lens of mirror condenser, the horizontal component of elbow links to each other with an end that passes photoconduction, the other end that passes photoconduction is installed in the bottom of indoor pot kettle, and its termination up.Pass and to be in line after photoconduction installs or to change quarter bend, pass photoconduction two kinds of structures are arranged: first straight line portion is the glass mirror pipe, its turning connects with elbow bend, and elbow bend is that the elbow of reflecting condensation mirror foci top is not adorned lens, and the lens end is become interface; It two is that inner core is cylindrical glass, and skin is the little glass round tube of refractive index ratio inner core refractive index, and the metal impurities purity of the outer field glass of inner core is reduced to several PPb (10 by purification ^-9) level, hydrogeneous compound is reduced to 1-2PPm (10 ^-6), when it changes 90 ° of angles, inboardly being curved the right angle and the outside is deformed into elliptic plane, the level of elliptic plane is wide and vertical high identical with the diameter that passes photoconduction, and it all becomes 135 ° angle with biography photoconduction axis.When vertical solar radiation light shines mirror condenser, light is reflected to the focus of mirror condenser, become the parallel solar radiation light of " being concentrated " behind the scioptics, the sunshine that " is concentrated " is passing photoconduction straight line portion light and is passing the parallel direct projection forward in photoconduction axis, total reflection then takes place by flat mirror reflects or at the interface of layer glass at the turning, light becomes again with pass the parallel light in photoconduction axis, until passing to bottom the indoor pot kettle.The energy of sunshine by cooker such as pot, kettle absorbs and food or water are given in radiation.

Owing to adopted above scheme, the solar radiation light that the condenser that is reflected " has concentrated " can pass to the place that people need solar energy, and people can be as common kitchen range like this, and use solar energy is cooked and cooked in the kitchen.

Figure is further described the utility model below in conjunction with drawings and Examples.

In Fig. 1, solar radiation light (3) condenser (4) that is reflected is reflected into confocal light shafts, light shafts scioptics (2) become the parallel rays of " concentrating ", and parallel rays is reflected by level crossing (1) and level crossing or layer glass interface (13) or is totally reflected to cooker (5) bottom.

In Fig. 2, on roof (14), install bracing frame (35), on bracing frame (35) metope (15) and the kitchen range top (16), install and pass photoconduction fixed support (8), if pass photoconduction, determine straight line portion, its port put in interface (30) or the connector (32), load onto elbow (7) at whole biography photoconduction (12) with the glass mirror pipe, if the inner core glass outer passes photoconduction, determine whole length, the length of straight line portion and elbow part curves elbow (7) to elbow part again under determining on whole length again.The biography photoconduction (12) that installs elbow (7) or curved good elbow (7) is installed on the fixed support (8), install water tank (17), the elbow (7) that is installed on the kitchen range top (16) can turn to its port and relative position, hole (18), have elbow (6) the lens end to put into hole (33), connector (26) links to each other with biography photoconduction (12).The center of circle of track (10) is determined to install bottom bracket (24) after on the intersection point of the horizontal median axis of elbow (6) and vertical centering control axis, regulate the thickness of elbow (6) middle washer (28) and (29), make lens (2) and the confocal point of mirror condenser (4), mirror condenser (4) is installed on the track (10), and the mirror on mirror condenser (4) is along installing support (11) on the limit again.

Among Fig. 6, hole (25) usefulness bolt is (14) solid bottom support (24) on the roof, by add the distance up and down that packing ring is regulated bottom bracket (24) on bolt between roof (14) and bottom bracket (24).

In Fig. 8 Figure 10, the rear portion of elbow (6) or the outer right-angle plane mirror of elbow (7) (1) or (34) fuses with bayonet socket and other parts, and assembling is during elbow, takes off after this part installs level crossing (1) or (34), refills this part.In Fig. 8, the lens end of elbow (6) is put packing ring (28) into and is put lens (2) again into, and then puts screens packing ring (29) into.
