Referring to Figure 1, a schematic and exemplary solar coffee / tea maker 100 is shown in vertical section.

The solar coffee / tea maker 100 includes a solar coffee / tea pot 160, a solar collector 110, and a connection conduit 171. The solar collector 110 is filled with a heat storage and conductive material 120.

The solar coffee / tea pot (160) is a liquid container containing a lid (162). In this case, the liquid container is a vacuum glass bottle 161. However, stainless steels and synthetic materials are also frequently used. A coffee / tea holder 166 is disposed within the port 160. The coffee / tea holder 166 has a lower portion of the car basket 167 that includes a removable lid 1671. The top of the coffee / tea holder 166 is a perforated coffee holder 168. The stand 169 supports the coffee holder 168 and the car holder 167. Both the coffee holder, the tea holder and the lid can be moved through the shaft 169. Depending on the cooking conditions, the coffee holder, car holder, or both may stay in port 160 or be removed out of the port.

The hot water shower head 164 is arranged at the center of the lid 162. The hot water conduit 163 passes through the lid 164 and the handle 165 of the port 160 and is concealed in the lid and handle. The hot water conduit 163 is connected to the hot water shower head 164 at one end. The other end of the hot water conduit 163 is connected to the component 170 at the bottom of the handle 165. The component 170 receives the hot water conduit 171 from the solar water heater 110.

The solar collector 110 may be any kind of solar collector capable of heating the heat storage and conductive material 120 to a temperature above the boiling point of water. In this case, the solar collector 110 is a vacuum tube solar collector. Or a group of modular vacuum tube solar collectors mounted in parallel rows or full or partial cone-shaped columns as in the example shown in FIG. The solar collector 110 has a removable portion 114 having two apertures 1141 and 1142. The hole 1141 is a path for power cable 151 and air exchange. The hole 1142 is intended to lead to the hole 1311 through which the hot water conduit 171 passes.

The vacuum tube solar collector 110 has a transparent outer layer 111 and an inner layer 112. A vacuum is formed between the two layers. The inner layer 112 has a heat absorbing coating, not shown in FIG. The vacuum tube solar collector 110 has the same materials and manufacturing process as the vacuum tube solar collector used for solar heating. However, the vacuum tube solar collector 110 used in solar cooking has a larger diameter and shorter length than a conventional vacuum tube for heating solar water.

The vacuum tube solar collector 110 is made of glass. In this case, the glass tube is fragile and the glass fragments are dangerous to the user. Accordingly, the solar collector 110 has a transparent plastic cover for safety reasons (not shown in FIG. 1). If the solar collector 110 is a group of vacuum tubes mounted in one row, a transparent plastic cover may cover each tube, or a plastic protective cover may cover the entire heat. However, the plastic protective cover can reduce the efficiency of the solar collector 110. Thus, a vacuum-enhanced glass tube solar collector is a better solution.

The vacuum tube solar collector 110 is filled with a heat storage and conductive material 120. In this case, the heat storage and conductive material 120 is salt or sand for storing the solar heat and delivering it to the water container 130. In fact, many kinds of materials can be used as heat storage and conductive materials. For example, the thermal storage and conductive material is a solid material such as salt, sand, graphite, and peat. The thermal storage and conductive material may be a liquid material such as water, oils including cooking oil, and petroleum products. The storage and conductive material may be a phase change material, such as paraffin. A combination of different materials may be selected, for example a mixture of silica and soybean oil.

The water container 130 is a cylindrical vessel disposed above the heat storage and conductive material 120 and disposed within the solar collector 110. The water container is made of stainless steel. The cooking appliance 130 has a removable portion 131 having a hole 1311 and the removable portion is a plug inserted into the cooking appliance 130. [ The cooking apparatus has a diameter which is close to the inside diameter of the vacuum tube 110 but not larger than that. The corrugated structures 133 are positioned on the walls of the vessel from top to bottom to provide airtight and spacing and pathways for the power cable 151. Further, the corrugated structure provides an adjustable small diameter for the vessel 130. The cooking apparatus 130 further includes a removable and detachable handle 134 on the inner wall for removing the cooking appliance 130 from the solar collector 110.

The removable portion 114 covers the top of the solar collector 110. The removable portion has two holes 1141 and 1142. The first hole 1141 is connected to the gap and path for air exchange and power cable. The second hole 1142 leads to the hole 1311 in the cap 131 of the container 130. [

The electric heating element 150 with the power supply is an electric heating element that consumes very low power. The electrical heating element is located below the water container 130 and within the heat storage and conductive material 120. The power cable 151 is connected to the power supply plug 152 through the path formed by the corrugated structure 133 on the wall of the cooking appliance 130, Strong resistance. The electric heating element 150 may further include a measuring, indicating, and controlling system for operating characteristic parameters such as timing, temperature, pressure, humidity, etc. for the solar cooker. The measurement, instruction and control system is not shown in Fig. An electric heating element with a power supply can be removed from the set of cooking utensils. In this case, the set of solar cookware is still a complete cookware that uses solar heat as the sole source of energy. Figure 3 shows a solar collector without an electric heating element.

The hot water connection conduit 171 extends through the holes 1142 and 1311 to the airtight container heated by solar heat. One end of the hot water connection conduit is submerged below the water level 135 within the heated water container 130. The other end of the hot water connecting conduit 171 is connected to a conduit connected to the part 170 at the handle 165 of the coffee / tea pot 160.

When the sunlight 101 illuminates the solar collector 110, the solar collector absorbs solar heat and stores solar heat in the sand 120. When the water container 130 is located in the solar collector 110 and cold water is poured into the container, the solar heat is transferred to the solar water container 130 through the inner wall 112, the heated sand 120, . The end 1711 of the conduit 171 is submerged below the water level 135 within the water container 130. The water container 130 is constructed in an airtight manner. When the water is heated and boiled, the water vapor gathered in the upper space of the vessel 130 forces the hot water to flow into the conduits 171 and 163. The hot water is then dispersed through the showerhead 164 to evenly fall onto the coffee grounds contained in the coffee holder 168. The hot water extracts the coffee liquid and flows into the coffee bottle 161. The coffee making process is completed. A similar process can be used to make a car. In this case, the tea or tea bag can be contained in the car basket 167.

The user may replace the water container by using the vacuum tube 110 itself. In this case, there is no water container 130, plug 131, and heat storage and conductive material 120 inside the solar collector 110. The removable portion 114 needs to make the collector 110 a gas-tight container. When solar heat boils the water in the vacuum tube 110, the water vapor in the vacuum tube 110 pressurizes the water upwardly through the conduits 171 and 163 to produce coffee. In this case, the rate and amount of coffee production depends on real-time solar power generation. Solar power generation may not be sustainable or stable. When the user uses the water container 130 located in the vacuum tube 160 filled with the heat storage and conductive material 120, the user can use the stored heat to make coffee and tea continuously and stably at any time.

If the solar heat is not enough to cook, the electrical element 150 heats the water container inside the solar collector 110. Since the tube 110 has very good thermal insulation characteristics, the required power is very low. In this case, electricity has a very high cooking efficiency.

Based on the idea of the solar coffee / tea maker shown in FIG. 1 and described above, the solar / electric coffee maker can change the drip coffee maker heated by electricity to a small extent, or refit the existing electric heated drip coffee maker Can be easily manufactured. Referring to FIG. 2, a schematic solar / electric coffee maker 200 is shown in vertical section. In order to simplify the description, the solar collector 110, the solar water heater 130, and the connection conduit 171, which are filled with the regenerative and conductive material 120, are the same as described in FIG.

The electric coffee maker 260 includes a cold water reservoir 261, an electric heating tube 262, a hot water tube 263, a hot water shower head 264, a perforated coffee holder 265, a coffee pot 266, And a valve 267. These components are the same as the general components that an electric drip coffee maker can have. Compared to a typical electric drip coffee maker, the main changes to the solar / electric coffee maker are:

The hot water tube 263 leads to the electric heating tube 262 and directs water from the base of the reservoir 261 to the drip region 265. This hot water tube 263 has a bypass tube 268 located above the first one-way valve 267 and the electric heating tube 262 but below the showerhead 264.

A second one-way valve 270 is added to prevent hot water from flowing back to the solar collector 110. One end of the second one way valve is connected to the end of the bypass tube 268 and the other end is connected to the connecting part 269 of the electric drip coffee maker 260 through the third tube 272.

When the sunlight 101 illuminates the solar collector 110, the solar collector absorbs solar heat and stores solar heat in the heat storage and conductive material 120. When the water container 130 is located in the solar collector 110 and cold water is poured into the container, the solar heat is transferred to the solar water container 130 through the inner wall 112, the heat storage and conductive material 120, do. The end 1711 of the conduit 171 is submerged in the water container 130. The water container 130 is constructed in an airtight manner. When the water is heated and boiled, the water vapor gathered in the upper space of the vessel forces the hot water to flow to the conduits 171 and 263. The hot water is then dispersed through the showerhead 164 so as to evenly fall onto the coffee grounds contained in the coffee holder 165. The hot water extracts the coffee liquid and flows to the coffee pot 266. The coffee making process is completed. When the solar collector 110 is operated, the added one-way valve 273 prevents water from flowing toward the electric heating tube 262. [

If the solar energy is not sufficient, connect the electric heating tube 162. The cold water flows from the first one-way valve 267 through 261 and is heated in the electric heating tube 262 until boiling. The droplets in the boiling water pressurize the hot water to the showerhead 264 through the hot water tube 263 to make the coffee. This process is the same as that of any kind of electric drip coffee maker.

Way valve 273 prevents water from flowing toward the electric heating tube 262 when the solar collector 110 is operating. When the electric drip coffee maker 260 is operated, the added one-way valve 272 prevents water from flowing toward the solar collector 110. If necessary, two heating sources may operate together.

As shown in FIG. 1, the hollow solar collector tube 110 can replace the hot water vessel 130 to heat water and make coffee.

Referring to FIG. 3, a set of exemplary solar collectors is schematically illustrated in vertical section.

When installing a solar cooker, more variety and combinations of these types of solar collectors as well as others can be selected and used.

Referring to Figure 4, an alternative solar cooking apparatus (steamer) is shown schematically in vertical section.

Again, to simplify the description, the solar collector 110, the solar water heater 130, and the connection conduit 171, which are filled with the regenerative and conductive material 120, are the same as shown in FIG.

The cooking appliance 460 is now a food gourmet with an insulated lid 462. The side walls of the cooking appliance 460 are insulated by a heat insulating coating 461. A three-layer steam basket 468 is arranged in the cooking utensil 460 on the floor 464. Food is cooked by steam. The steam tube 463 is arranged inside the cooking apparatus along the inner wall of the steamer 460 from the upper part to almost the bottom. The tube 463 is connected to the connecting part 465 from the insulating coating 461.

The connecting conduit 471 has one end 1711 connected to the connecting part 465. The other end 1712 of the connecting conduit 171 extends above the hot water vessel 130 and the water level 135.

When the sunlight 101 illuminates the solar collector 110, the solar collector absorbs solar heat and stores solar heat in the heat storage and conductive material 120. When the water container 130 is located in the solar collector 110 and cold water is poured into the container, the solar heat is transferred to the solar water container 130 through the inner wall 112, the heat storage and conductive material 120, Heat until done. The water vapor generated in the vessel 130 rises through the tubes 171, 463, and 467 to the cooking appliance 460 and cooks the food in (460).

Figure 5 schematically shows in vertical cross-section a set of solar cooking appliances 500 using a heating tube as a heat transfer medium.

The solar collector 510 is a group of five modular vacuum tube solar collectors mounted in a row. In this case, the number of modular vacuum tubes is five, but the number can be changed according to the cooking condition. The solar collector 510 is filled with the convergent tube 516 and the vacuum tube 511, 512, 513, 514 and 515 both with the peat 520.

The cooking apparatus 561 is disposed in the insulating mantle 562. The cooking utensil has two layers of glass lids 563 with holes 5631. At the bottom wall of the cooking appliance 561, the component 565 is arranged to receive the heating tube 530 from the solar collector 510.

One end of the heating tube 530 is directed to a converging tube 516. The other end of the heating tube is inserted into the component 565 in the cooking apparatus 561. Both ends of the converging tube 561 are adjacent and insulated.

When the solar collector 510 is in operation, the vacuum tube absorbs heat and stores heat in peat in the solar collector 510. The heating tube 530 conveys the solar heat to the cooking device 561 for cooking food. After cooking, the cooking apparatus 561 is taken out of the heat insulating jacket and replaced with a heat insulating mass. This is to keep the solar cooking system at a high operating temperature for the next dish.

6 schematically illustrates in vertical cross-section an alternative solar cooking apparatus 600 that transfers solar heat by a direct connection between the graphite 620 in the solar collector 610 and the graphite under the cooking appliance 661. [

The solar collector 610 is a vacuum tube solar collector. The solar collector 610 is filled with graphite.

The cooker 661 with the lid 663 is located in an insulating mantle 662 with a lid 664. There is a space 665 between the bottom of the cooking apparatus 661 and the coat 662. The space is also filled with graphite. The end of the vacuum tube 610 extends into the space 665. The solar collector 620 and the graphite 620 in the space 665 are closely connected.

When the solar collector is in operation, the collected solar heat is transferred from the graphite in the vacuum tube to the graphite in the space 665. The solar heat cooks the food in the cooking apparatus 661. In some embodiments, a thermal conductor may be added between the solar collector 610 and the space 665 for rapid transfer of solar heat. The thermal conductor may be a heating tube.

Generally, a vacuum tube is mounted in a row to cook multiple foods at the same time.

Referring to Fig. 7, a set of solar cooking utensils 700 is schematically shown in a perspective view and a vertical sectional view, respectively.

The five vacuum tube solar collectors 701, 702, 703, 704 and 705 are mounted in parallel rows as shown in the perspective view. Five cooking utensils 160, 260, 460, 560 and 660, including a coffee / tea maker, are placed on one side of the solar collector 710 and are shown in vertical section. Each solar collector is filled with a different heat storage and conductive material and is connected to the cooking device in a manner different from that shown in FIGS. 1, 2, 4, 5 and 6. The connection between the solar collector and the cooking appliance on the ground is not shown in Fig.

The retention and support platform 706 arranges and supports five solar collectors in the right location and situation. The movable support 707 allows the incidence angle of the solar collector 710 to be adjusted toward the sunlight. Four wheels 741, 742, 743 and 744 are installed at the four lower corners of the support pedestal 706 to regulate the direction of the solar collector 710 (743 and 744 are not shown in Figure 7) . The sundial (not shown in Fig. 7) is a cone-shaped bar. The sundial is attached vertically to the solar collector 710 to indicate the incident angle of sunlight.

A light reflection object (not shown in Fig. 7) is mounted under the vacuum tube to collect the surrounding sunlight to the solar collector.

When the solar light illuminates the solar collector 710, the cooking process in each cooking appliance is the same as that described in Figs. 1 to 6. This process will not be repeated again.

Based on the detailed description of this embodiment, one of ordinary skill in the art will recognize other variations, and thus the invention is defined by the claims.
