Description

Technical Field

[0001] The present invention is a new technology and a new method for heating food and water in daily life, specifically, converting microwaves into high-power terahertz waves for heating food and water. Background Art

[0002] Almost all commonly used heating methods so far include (gas) combustion heating, induction cooker heating, electric stove heating, oven heating, microwave oven heating, light wave oven heating, infrared heating, etc. The present invention can also be regarded as an innovative upgrade of microwave oven heating, avoiding many disadvantages of microwave oven heating, such as some utensils and food cannot be heated in a microwave oven, but there is no problem in putting them in a terahertz wave oven.

[0003] The principle of converting microwaves into high-power terahertz waves can be found in invention patent ZL201310504041.X. The present invention innovatively transforms this principle and method, solving the problems of electron escape and breakdown on the metal mesh surface of the converter, heating and desoldering of the metal frame, etc. It not only increases the terahertz wave conversion rate to more than 95%, but also makes the converter safer and more reliable, thus meeting the application needs of terahertz wave heating furnaces. Summary of the invention

[0004] The purpose of the present invention is to provide a terahertz wave heating furnace device, which includes three parts (functional areas), a microwave generating studio 17, a terahertz wave conversion box 19, a heating chamber 10, Figure 1 This is a front view of the terahertz wave heating furnace.

[0005] The microwave generating studio 17 has the same microwave generating principle as an ordinary microwave oven. In order to meet the working needs of the terahertz heating furnace, it is considered to add a built-in exhaust fan on the front (or back) thereof, and to open a φ2.5mm hole group 15 at the corresponding front (or back) position, with a small hole spacing of 1mm, so that a group of small hole groups form a circular diameter of about 8 cm, which is used to enhance the heat dissipation of the microwave generating studio and indirectly assist the heat dissipation of the terahertz wave conversion box 19.

[0006] The central structure of the terahertz conversion box 19 is a converter 4, which converts microwaves into terahertz waves. The conversion principle is described in the invention patent: ZL201310504041.X. To adapt to the application of heating furnaces, we transform the two-stage conversion design used in the ZL201310504041.X patent into a one-stage conversion, which can greatly save space. At present, its structure is a rectangular parallelepiped with a length of 20 cm, a width of 16 cm, and a thickness of 12 cm: including 9 layers of 120-160 mesh copper mesh arranged in parallel at equal intervals (each layer of copper mesh is a plane parallel to the microwave emission port), and 2 layers of 120-160 mesh copper mesh are wrapped around it, so that its six faces are all copper mesh. In order to fix, copper brackets are welded on the four sides of each layer of the nine-layer copper mesh, and copper rods are also used to weld the nine layers of copper mesh; there should be enough safety distance between the converter 4 and the microwave emission port 1.

[0007] In addition to transforming the two-stage conversion mode design into a one-stage conversion mode, further technical innovation is required to meet the application needs of the terahertz heating furnace, as follows: the six faces of the converter 4 rectangular parallelepiped are covered with high-temperature resistant insulating cloth 5, which prevents leakage caused by the escape of electrons on the surface of the converter 4 and oxidation of the copper mesh of the converter 4 itself, thereby enhancing the safety of the converter 4, which is an improvement on the original invention patent ZL201310504041.X.

[0008] Then, outside the high-temperature resistant insulating cloth 5, two surfaces parallel to the microwave emission port are respectively attached with 1.5 mm to 2 mm thick mica plates 7, and the other four surfaces perpendicular to the microwave emission port are surrounded and covered with 5 mm thick surrounding glass 6. The joints between the two mica plates 7 and the surrounding glass 6 are sealed with silicone. Such a combination further prevents the leakage and escape of high-energy electrons on the surface of the converter 4, so that more pulsed terahertz waves are generated while generating terahertz continuous waves, thereby improving the conversion efficiency of terahertz waves. This is another innovative improvement to the original invention patent ZL201310504041.X.

[0009] In the area of ​​the terahertz wave conversion box 19, on the inner side of the front panel (the front facing the user), 3 to 4 layers of 100-mesh stainless steel mesh 15 are pasted, whose function is to prevent the terahertz waves from escaping from the wind inlet tunnel 21 and the wind outlet tunnel 18 to the outside space. This is to prevent energy loss and to prevent the escaping terahertz waves from interfering with the normal operation of electrical appliances.

[0010] In the terahertz wave conversion box 19 area, there are many inlet holes 21 (φ0.25cm) in the middle of the front panel; there are many outlet holes 18 (φ0.25cm) above and below the front panel in this area; the hole spacing is 0.1cm. The function of the inlet hole 21 and the outlet hole 18 is to use air to cool the converter 4, the high-voltage and high-temperature resistant insulating cloth 5, the surrounding glass 6, and the positive and negative mica plates 7.

[0011] The inlet fan 8 and the inlet fan cover 14 are fixed to the middle outer side of the front panel of the terahertz wave conversion box 19. The inlet fan transports the outside air to the terahertz wave conversion box 19 through the air inlet tunnel 21, and then discharges the hot air to the outside air from the air outlet tunnel 18 through air pressure after heat exchange. The function of the inlet fan cover 14 is to prevent foreign objects from contacting the inlet fan. (Supplementary explanation: For the sake of aesthetics, the inlet tunnel 21 and the air outlet tunnel 18 of the conversion box 19 are likely to be opened by the manufacturer on the back shell of the terahertz furnace during actual manufacturing. Then 3 to 4 layers of 100 mesh stainless steel wire mesh should also be attached to the inner side of the back shell, and the inlet fan 8 and the inlet fan cover 14 are also installed on the back. It should be pointed out that considering that some users may place electrical appliances against the wall, and heat dissipation is crucial to the terahertz wave converter 4, arranging the above contents on the front will be more conducive to heat dissipation and safety observation. If arranged on the back, necessary safety design should be added and corresponding safety tests should be performed).

[0012] A 5 mm thick glass partition 9 is placed on one side of the terahertz wave conversion box 19 adjacent to the heating chamber. The glass partition 9 separates the heating chamber 10 and the terahertz wave conversion box 19, which is beneficial to the cooling of the converter 4, the high temperature resistant insulating cloth 5, the surrounding glass 6, the positive and negative mica boards 7 and the area near the microwave emission port, and also prevents users from contacting the terahertz wave conversion box 19.

[0013] The movable door 12 of the heating chamber 10 is pasted with 3 to 4 layers 16 of stainless iron mesh with 80 to 100 meshes. The structure of the movable door 12 is the same as that of the movable door of an ordinary microwave oven. Although the door of an ordinary microwave oven is originally pasted with a net to prevent microwave leakage, its aperture is not sufficient to block the leakage of terahertz waves. Therefore, it is advisable to paste 3 to 4 layers 16 of tightly overlapping stainless iron mesh (80-100 meshes) on the inner side of the movable door 12. The specific arrangement should ensure that the heating chamber can still be observed through the door glass during the heating process.

[0014] The heating chamber 10 is built with a square or round high temperature resistant tray 22, which is to prevent the liquid from overflowing into the heating chamber 10 due to high temperature boiling, thereby affecting the safety of the glass partition 9. The side height of the tray is 1.5 cm. The tray can be made of a specific metal material with good terahertz wave reflection performance and high cost performance, or a suitable non-metal material such as glass.

[0015] The present invention will now be further described in conjunction with an application example and accompanying drawings.

[0016] Figure 2 The front view of a terahertz wave heating furnace of the present invention is marked with approximate reference dimensions, and it includes three parts (areas): the first part is a microwave emission studio 17, which includes an oscillating tube, a high-voltage transformer, an oscillating tube cooling fan, a rectifier diode, a fuse, a lighting lamp 24, a timer 2, an emission port 1, etc., and an exhaust fan 3 (installed in the panel) and an air outlet tunnel 20 are additionally added compared to an ordinary microwave oven. The large, medium and small gear switches of the original microwave oven are cancelled as optional items in this example;

[0017] The second part is a terahertz wave conversion box 19, including a converter 4 (for the principle, see invention patent: ZL201310504041.X), high-voltage and high-temperature resistant insulating cloth 5, glass 6 (5 mm thick) wrapping the four sides of the converter 4 perpendicular to the microwave emission port, two sides of the converter 4 parallel to the microwave emission port are each affixed with a mica board 7 (1.5-2 mm thick), an inlet fan 8 is installed on the outside of the front panel, an air inlet hole 21 (φ0.25 cm, hole spacing 1 mm) and an air outlet hole 18 (φ0.25 cm, hole spacing 1 mm) are provided on the front panel, three to four layers of stainless iron mesh 15 (about 80 meshes-100 meshes) are embedded on the inner side of the conversion box 19 panel, and a glass partition 9 (5 mm thick) is provided between the terahertz wave conversion box 19 and the heating chamber 10 to separate the two areas;

[0018] The third part is the heating chamber 10. Since the converter 4 as a terahertz wave emission source has emission uniformity, it is possible to freely choose whether to cancel the turntable rotation function commonly found in microwave oven heating chambers. In order to prevent the terahertz wave from leaking out from the movable door 12, 3 to 4 layers of overlapping stainless steel meshes 16 (about 80-100 meshes) are attached to the inner side of the movable door 12. In order to prevent the heated object from leaking out and affecting the terahertz wave conversion box 19, a metal (or glass) tray 22 is built in, and the tray edge is about 1.5 cm high.

[0019] Figure 3 is a top view of a terahertz wave heating furnace of the present invention, except for the corresponding Figure 1 and Figure 2 In addition to the instructions, it is also indicated that a side stainless iron mesh 23 (100 mesh 3 to 4 layers) is installed on the outside of the microwave emission port 1 of the microwave oven studio 17, and many small holes (φ0.2cm, hole spacing 0.15cm) are opened on the outside of the emission port 1 to allow the lighting lamp 24 to irradiate into the heating chamber. These small holes will leak terahertz waves and affect the normal operation of all electrical appliances in the microwave oven studio. The role of the stainless iron mesh 23 (100 mesh 3 to 4 layers) is to prevent the leakage of terahertz waves. BRIEF DESCRIPTION OF THE DRAWINGS
