Other aspects and features of the present invention will become apparent to those skilled in the art when the following detailed description of specific embodiments of the present invention is referred to in conjunction with the accompanying drawings.

Referring to FIG. 1, a schematic and exemplary solar coffee / tea maker 100 is shown in a vertical sectional view.

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

Solar coffee / tea pot 160 is a liquid container including lid 162. In this case, the liquid container is a vacuum glass bottle 161. However, stainless steel and synthetic materials are also often used. Coffee / tea holder 166 is disposed in pot 160. Coffee / tea holder 166 has a bottom of tea basket 167 that includes removable lid 1701. Top of coffee / tea holder 166 is perforated coffee holder 168. Stand 169 supports coffee holder 168 and tea holder 167. The coffee holder, tea holder and lid can all be moved through the shaft 169. Depending on the cooking conditions, the coffee holder, the tea holder, or both may stay in or be removed from the pot 160.

The hot shower head 164 is arranged at the center of the lid 162. The hot water conduit 163 passes through the handle 165 of the lid 164 and the port 160 and is concealed within the lid and the 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. Component 170 receives hot water conduit 171 from 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. It may be a specific form, such as a group of modular vacuum tube solar collectors mounted in parallel rows or complete or partial cone shaped columns such as the example shown in FIG. 7. The solar collector 110 has a removable portion 114 having two holes 1141 and 1142. Hole 1141 is a path for power cable 151 and air exchange. The hole 1142 is for leading to the hole 1311 so that the hot water conduit 171 passes.

Vacuum tube solar collector 110 has a transparent outer layer 111 and an inner layer 112. A vacuum is formed between the two layers. Inner layer 112 has a heat absorbing coating that is not shown in FIG. 1. Vacuum tube solar collector 110 has the same materials and manufacturing processes as vacuum tube solar collectors used for solar water heating. However, the vacuum tube solar collector 110 used for solar cooking has a larger diameter and shorter length than conventional vacuum tubes for solar water heating.

The vacuum tube solar collector 110 is made of glass. In this case, the glass tube is fragile and the glass pieces are dangerous to the user. Thus, 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 a row, a transparent plastic cover may cover each tube, or a plastic protective cover may cover the entire row. However, the plastic protective cover can reduce the efficiency of the solar collector 110. Thus, a glass tube solar collector powered by vacuum is a better solution.

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

The water container 130 is a cylindrical container disposed over the heat storage and conductive material 120 and disposed inside 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, which is a plug inserted into the cooking appliance 130. The cooking appliance has a diameter that is close to but not larger than the inner diameter of the vacuum tube 110. Corrugated structure 133 is located on the wall of the vessel from top to bottom, providing a gap and path for air exchange and power cable 151. Furthermore, the corrugated structure provides an adjustable small diameter for the vessel 130. The cooking appliance 130 further includes a removable handle 134 that is removable on the inner wall to remove 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. First hole 1141 is connected to the gap and path for air exchange and power cables. The second hole 1142 leads to the hole 1311 in the stopper 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 under the water container 130 and is located in the heat storage and conductive material 120. The power cable 151 is connected to a heating temperature for connecting the electric heating element to the power plug 152 outside the solar collector 110 through a path formed by the corrugated structure 133 on the wall of the cooker 130. Strong resistance The electrical heating element 150 may further include a measurement, indication and control system for manipulating characteristic parameters such as timing, temperature, pressure, humidity, etc. for the solar cooker. The measurement, indication and control system is not shown in FIG. The electrical heating element with the power supply can be removed from the set of cookware. In this case, the set of solar cookers is still a complete cookware that uses solar heat as its only energy source. 3 shows a solar collector without electric heating elements.

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

When sunlight 101 illuminates solar collector 110, the solar collector absorbs solar heat and stores solar heat in 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, and heats the water. . End 1711 of conduit 171 is submerged below water level 135 in water container 130. The water container 130 is configured to be airtight. When the water is heated and boiled, the water vapor collected in the upper space of the vessel 130 exerts a force on the hot water to flow to the conduits (171 and 163). The hot water is then distributed evenly over the coffee powder contained on the coffee holder 168 through the shower head 164. The hot water draws out the coffee liquid and flows to the coffee bottle 161. The coffee making process is complete. Similar processes can be used to make tea. In this case, the tea or tea bag may be contained in the tea 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, a stopper 131, and a heat storage and conductive material 120 inside the solar collector 110. The removable portion 114 needs to make the collector 110 an airtight container. When solar heat heats and boils water in the vacuum tube 110, the water vapor in the vacuum tube 110 pressurizes the water upwards through the conduits 171 and 163 to make coffee. In this case, the speed and amount of coffee production depends on real-time solar power generation. Solar power generation may not be sustainable or stable. When a user uses a water container 130 located within a vacuum tube 160 filled with 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 solar heat is not sufficient to cook, electrical element 150 heats the water container inside solar collector 110. Since the tube 110 has very good thermal insulation characteristics, the power required is very low. In this case, the 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 make minor changes to an electrically heated drip coffee maker, or by refurbishing an existing electrically heated drip coffee maker. It can be easily manufactured. Referring to FIG. 2, a schematic solar / electric coffee maker 200 is shown in a vertical sectional view. To simplify the description, the solar collector 110, solar water heater 130 and 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 shower head 264, a perforated coffee holder 265, a coffee pot 266 and a first one-way direction. A valve 267 is provided. These parts described above are the same general parts that an electric drip coffee maker can have. Compared with conventional electric drip coffee makers, the main changes of solar / electric coffee makers are as follows:

Hot water tube 263 leads to an electric heating tube 262 and directs water to the drip region 265 at the base of the reservoir 261. 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 shower head 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 via a third tube 272.

When sunlight 101 illuminates 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 the conductive material 120, and heats the water. do. End 1711 of conduit 171 is submerged under water in water container 130. The water container 130 is configured to be airtight. When the water is heated and boiled, the steam collected in the upper space of the vessel forces hot water to flow into conduits 171 and 263. The hot water is then dispersed to evenly fall on the coffee powder contained on the coffee holder 165 via the shower head 164. The hot water draws out the coffee liquid and flows to the coffee pot 266. The coffee making process is complete. When the solar collector 110 is in operation, the added one-way valve 273 prevents water from flowing towards the electrical heating tube 262.

If there is not enough solar energy, the electric heating tube 162 is connected. Cold water flows from 261 through first one-way valve 267 and is heated in electric heating tube 262 until it boils. The drops in boiling water pressurize the hot water through the hot water tube 263 to the shower head 264 to make coffee. The process is the same as in any kind of electric drip coffee maker.

When the solar collector 110 is in operation, the one-way valve 273 prevents water from flowing towards the electrical heating tube 262. When the electric drip coffee maker 260 is in operation, an added one-way valve 272 prevents water from flowing towards the solar collector 110. If necessary, two heating sources may work together.

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

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

Referring to FIG. 4, an alternative solar cooker is shown schematically in a vertical sectional view.

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

The steam tube 463 is arranged inside the cooker along the inner wall of the steamer 460 from the top to the bottom. The tube 463 is connected to the connecting component 465 in the thermal insulation coating 461.

The connection conduit 471 has one end 1711 connected to a connection component 465. The other end 1712 of the connection conduit 171 extends above the hot water container 130 and the water level 135.

When sunlight 101 illuminates 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 the conductive material 120, and to boil the water. Heat until The steam generated in the vessel 130 goes up through the tubes 171, 463, and 467 to the cooking appliance 460 to cook the food in 460.

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 may be changed according to cooking conditions. The solar collector 510 is filled with peat 520 inside both the converging tube 516 and the vacuum tubes 511, 512, 513, 514 and 515.

The cooking appliance 561 is disposed in the insulating coat 562. The cooker has two layers of glass lids 563 with holes 5631. At the bottom wall of the cooker 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 the converging tube 516. The other end of the heating tube is inserted into the component 565 in the cooker 561. The two 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 the heat in peat in the solar collector 510. The heating tube 530 transfers solar heat to the cooking appliance 561 for cooking food. After cooking, the cooking appliance 561 is taken out of the heat insulating coat and replaced with the heat insulating mass. This is to maintain the solar cooking system at a high operating temperature for the next dish.

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

In general, vacuum tubes are mounted in a row to cook multiple foods at the same time.
